Description

This invention relates to a switch cabinet for receiving the components of a serial lighting device for acrodromes, wherein the serial lighting device includes at least one system for switching on lamps and monitoring.

Known switchgear cabinets of this type are designed so that they can accept components assigned to one series circuit of a series lighting device for one airport.

It is known that in the serial circuits of a serial lighting device of this type, an individual system for switching on lamps and monitoring is foreseen, so that each individual lamp can be switched on and controlled. The system for switching on and controlling lamps of this type consists of one central (master) unit, one personal computer (PC) and external (separate) connecting units. These components are required in addition to the existing components of the serial lighting device.

In known serial lighting devices, the central unit of the individual system for turning on lamps and monitoring is placed in a special tin case. The central unit of such an individual BRITE II lamp and performance monitoring system is housed in a special sheet metal housing 508 mm wide, 673 mm high and 237 mm deep. This separate sheet metal housing is placed on the free wall of the space where the switch cabinets equipped with components for the serial circuit are located. Since a unit of this type is required for each serial circuit, a large space or a large surface area of the walls is required for the accommodation of such pentral units.

The task of this invention is to make available to airports a switching cabinet for receiving the components of a serial device, by means of which, related to the technical side of the housing, the cost could be significantly reduced while at the same time improving functionality.

According to this invention, this task will be solved by selecting the dimensions of the switch cabinet in such a way that the switch cabinet can accommodate more, preferably at least three serially connected transformers, a carrier of measuring components and a constant current regulator, and that each carrier of measuring components is constructed in such a way that a central unit can be placed on it, which has at least one individual system for attaching lamps and controls and one interface, and one communication connecting element between the serial circuit and the constant current regulator assigned to it. In this way, compared to the previous performance, space is significantly saved. At least three central units can be placed in each switch cabinet, as well as series-connected transformers assigned to the corresponding series circuits, a carrier for measuring components and a constant current regulator. The overall functional units, which are provided in the switch cabinet, can be placed clearly. In this way, it is possible to achieve optimal performance of the modules in terms of economic and technical-constructive costs.

Each carrier of measuring components that is provided in the switch cabinet is designed in such a way that it can accept functional components, without the previously described individual system of switching on lamps and monitoring, it is also possible to place individual components of the central unit of the individual system of switching on lamps on the carrier of measuring components and supervision. In this way, the separate tin casing of the central unit is removed. In this way, a great saving of space is achieved, because a wall is no longer needed to place the central units. The lamp transformer is removed from the measuring component carrier when applying the individual lamp switching and monitoring system, so that there is plenty of space available on the corresponding measuring component carrier to house the components of the central unit of the individual lamp switching and monitoring system.

According to the state of the art, the existing overvoltage protection components on the necessary separate tin case of the central unit on the consumer side can be removed, since the components of this type are located on the existing support of the measuring components in the switch cabinet.

An expedient division of the internal space of the switch cabinet is achieved if the series-connected transformers are placed in the lower part, the measuring component carriers in the middle, and the constant current regulator in the upper part of the switch cabinet.

If possible, in the vertical direction of the switch cabinet, safety disconnect switches for the serial circuits of the serial device for signal illumination are placed between the carriers of the measuring components and the series-connected transformers.

Due to the connection to the primary supply voltage source, it is expedient for the switch cabinet to have a collection device for the primary supply voltage, which can preferably be connected to the collection devices of neighboring switch cabinets.

The control module of the central unit can be placed horizontally next to the isolation monitoring module on the last of the measuring component supports.

It is recommended that the filter chokes of the central unit are placed in the vertical direction below their control module and isolation control module on the last of the measuring component supports.

The high-frequency module of the central unit is provided in the horizontal direction next to the filter chokes of the central units on the support of the measuring components.

The filter capacitors of the central unit are placed in the vertical direction below the filter chokes of the central unit and above the overvoltage discharge conductors and connection feet as well as the voltage transformer on the last of the measuring component supports.

Through the previously described arrangement of the components of the central unit as well as the building elements provided on each support of the measuring components, their function can be ensured, which cannot be influenced by each other.

For expediency, each carrier of the measuring components has a modular sheet.

The switch cabinet according to this invention is composed, if possible, of modules that can vary and be assembled, so that due to its dimensions it can be adapted to different situations without large technical-constructive costs.

Furthermore, the invention will be described in more detail using the embodiment and drawings. The drawings show:

Sl. 1 perspective view of one embodiment of the switch cabinet according to the present invention,

Sl. 2 schematic representation of the individual lamp and control system, i

Sl. 3 one version of the carrier of the measuring components in the switching cabinet according to Fig. l,

The switch cabinet according to this invention shown in FIG. 1 in a perspective view and in a partially disassembled state is composed of modularly connectable wall parts and extension parts as well as doors. It serves to accept various components of the serial device for signaling lighting for airports.

In the shown embodiment, the wardrobe is divided into upper, middle and lower parts.

The upper part can be used as an extension part 2, which is not closed on the front side, while on the contrary, the lower and middle part can be closed using two doors 3, 4.

In the upper part or the extension part 2 of the switchgear cabinet 1, more than three constant current regulators 5, 6, 7 are received next to each other in the shown embodiment, of which the constant current regulator 5 is placed in Fig. 1 left, in exploded view.

The constant current regulator 5, 6, 7 is a thyristor constant current regulator, where the construction type MCR 5000 or 6SF51 is optionally used. The constant current regulators 5, 6, 7 are arranged next to each other in a modular manner inside the extension part 2 of the switch cabinet.

In the middle part of the switching cabinet 1, in the shown embodiment, three supports for measuring components 8, 9, 10 are received, of which in Fig. 1 shows the carrier of measuring components 8 in an exploded view. Also three supports of measuring components 8, 9, 10 are placed next to each other in one row.

Under the three supports of the measuring components 8, 9, 10 is placed a series of safety disconnect switches 11, which can be partially seen in the exploded view, are made with two poles and are used to individually disconnect the serial circuits of the serial device for signal lighting.

A collection device 12 is provided under the safety disconnect switches 11, which can be equipped so that it can be connected to the correspondingly designed collection devices of adjacent switch cabinets. The collection device is designed to receive the supply voltage.

Series-connected transformers are placed under the collection device, of which Fig. 1 shows only one serially connected transformer 13 and can only be seen in its disassembled state.

The previously described arrangement of the components of the serial device for signal lighting provided in the switch cabinet 1 allows safe and smooth operation of the device, while the need for space is minimal. Furthermore, a universal cabinet can be used as a switch cabinet 1 in a wide range of applications.

An integral part of the serial device for signal lighting, which can take over the components in the switching cabinet 1, is an individual system for turning on lamps and controls, preferably of the BRITE II type. In this way, each signal light of the series circuit 14 shown in principle in Fig. 2, individually switch on and control. This individual system for turning on lamps and monitoring has as a component the central unit 15, a personal computer 16 and external (separated) units for turning on or remote controls 17 to 26.

The central unit 15 forms an interface and communication connecting element between the serial circuit 14 and the constant current regulator 5. It is connected to the personal computer 16, which represents a unit for management, data storage and as a connecting element for the central unit 15 and from its side is connected to the central control point.

External (separated) units for switching on or remote units 17 to 26 are placed, for example, between the transformer of the lamps 27 and the signal lamps 28.

The specified components are additionally required in addition to the existing components of the serial device for signal lighting.

In the case of switch cabinet 1 made according to this invention, its measuring component supports 8, 9, 10, as can be seen from Fig. 3 designed in such a way that individual building elements of the central unit 15 can be placed on them. In this way, the central unit 15 of the system for switching on lamps and control 15 to 26 can be accommodated inside the switching cabinet 1.

When using the above-mentioned lamp switching and monitoring system 15 to 26, the otherwise necessary lamp transformer on the measuring component support 8, 9, 10 is removed, so that then there is plenty of space available for receiving the central unit 15 on the measuring component support 8, 9, 10.

The control module 30 of the central unit 15 is placed next to the insulation control module 29 of the support of the measuring components 8, 9 and 10 respectively.

Below the isolation control module 29, the support of the measuring components 8, 9 and 10 and the control module 30 of the central unit 15 are located in the embodiment shown in Fig. 3 two filter chokes 31, 32 as well as the high-frequency connection module 33, which are integral parts of the central unit 15.

Below the filter chokes of the central unit, on the support of the measuring components 8, 9 and 10, respectively, in the illustrated embodiment, there are three filter capacitors 34, 35, 36, which are also integral parts of the central unit 15.

Under the filter capacitors 34, 35, 36, on the support of the measuring components 8, 9, and 10, respectively, in the illustrated embodiment, two surge arresters 37, 38 are provided, as well as two connection feet 39, 40 equipped with two clamps, between which there is a voltage transformer 41 Both surge arresters 37, 38, both connection feet 39, 40 as well as the voltage transformer 41 are not integral parts of the central unit 15.

For the reception of individual components, which should be placed on the carrier of the measuring components, the carrier of the measuring components can be made as a modular sheet 42.
