Abstract
The utility model relates to a permanent magnet driving low pressure air switch, which comprises a casing (10), an incoming line terminal (1), and an outgoing line terminal (13). The incoming line terminal is connected with a static contact (3), the static contact (3), a movable contact (4), and an iron grill sheet (2) are in an arc extinguish chamber (16), the primary line (12) of a main circuit connects the movable contact (4) with the outgoing line terminal (13), a movable contact supporting frame (6) is connected with the protruding end of a movable iron core (8) of a permanent magnet mechanism (9) through a connecting rod (7), the permanent magnet mechanism (9) and the movable contact supporting frame (6) are fixed on a locating frame (11), and the connector lug (14) of the permanent magnet mechanism is connected with a controlling line. The permanent magnet driving low pressure air switch can be widely applied to locations of online protection control, automatic detection electric failure disconnection, long-distance remote control closing and automatic reclosing in a power distributing system, and has the advantages that the quantity of the components is small, the processing, the installation and the overhaul are convenient, the disconnection ability of the switch is strong, and the air switch can be used in situations with frequent movements.
Description
Technical field
The utility model relates to a kind of low-voltage air switch that carries out divide-shut brake that driven by permanent magnetism.
Background technology
Existing low-voltage air switch carries out breaking-closing operating with spring operating mechanism, and spring operating mechanism exists that part is many, machining accuracy is high, complex manufacturing, product reliability be cannot say for sure card to use in the occasion of frequent movement.Though another kind of simple in structure but heavy as the low-voltage alternating-current contactor of electromagnetic operating mechanism, the closing coil consumed power is very big, the contact easy burn-out of dynamic/static contact, breaking capacity is low, can not detect the disconnection of electric fault automatically, and the scope of application has limitation.
Summary of the invention
The purpose of this utility model is at the above-mentioned deficiency of existing operating mechanism, a kind of high breaking capacity of existing air switch is provided, but the permanent-magnetic driven low-voltage air switch of the characteristic of A.C. contactor frequent movement is arranged again.
The purpose of this utility model can realize by following measure: a kind of permanent-magnetic driven low-voltage air switch, including shell, input terminal, outlet terminal, input terminal links to each other with fixed contact, fixed contact, moving contact, iron railings sheet are arranged in the arc control device, the primary line of main circuit connects moving contact and outlet terminal, moving contact rack links to each other with the moving iron core external part of permanent magnet mechanism by connecting rod, permanent magnet mechanism and moving contact rack are fixed on the locating rack, and the wiring chieftain of permanent magnet mechanism connects control circuit.
The purpose of this utility model can also be come perfect by following measure: be connected with the tension force connecting rod between the moving iron core external part of permanent magnet mechanism and the locating rack; Between dynamic contact mechanism and the locating rack extension spring is arranged.
The beneficial effects of the utility model are that parts are few, and processing, installation and maintenance are convenient, and the breaking capacity of switch is strong, can use in the occasion of frequent movement.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the permanent magnet mechanism structural representation.
Embodiment
The utility model is described in further detail below in conjunction with embodiment and with reference to accompanying drawing: with reference to Fig. 1, to be improved to permanent magnet mechanism 9 drivings with hand or electric control air switch in the prior art, during combined floodgate, operating current arrives primary line 12 through input terminal 1, fixed contact 3, iron railings sheet 2, moving contact 4, arrive outlet terminal 13 again, at this moment the closing coil 17 in the permanent magnet mechanism 9 passes through switching current, produce induced field, strength to moving iron core 8 oriented extrapolations, make the external part of iron core 8 extend the longest, the closing coil current vanishes, closing a floodgate is in the permanent magnetism hold mode.When switching winding 18 passes through to divide brake current, contract (as shown in Figure 1, 2) in the moving iron core 8, just, moving contact 4 is pulled away from fixed contact 3 by connecting rod 7, moving contact rack 6, realized separating brake.In the process of divide-shut brake, permanent magnet 19 provides magnetic energy, makes the usefulness of combined floodgate, has reduced the energy requirement to closing coil relatively, thereby can reduce the dimensions and the operating current of closing coil.Tension force connecting rod 15 has the effect that disperses and relax actuating force, thereby extension spring 5 is pulled away from the effect that reduces generation electric arc in the arc chamber 16 fast when helping separating brake.Locating rack 11 is with stationary positioned such as permanent magnet mechanism 9, moving contact rack 6, connecting rod 15, extension springs 5, and the wiring chieftain 14 of permanent magnet mechanism 9 connects control circuit, and control circuit carries out the specific aim design according to the difference of this air switch application places.Air switch and permanent magnet mechanism are different according to use occasion, set relevant parameter and are made.
This permanent-magnetic driven low-voltage air switch can be widely applied to the online protection control in the distribution system, the place of detecting electric fault disconnection and long-distance remote control closure and automatic reclosing and acting frequently automatically.
