Description

A temperature and humidity detection device inside a switch cabinet

technical field

The invention relates to the technical field of power equipment, in particular to a temperature and humidity detection device inside a switch cabinet.

Background technique

The southern part of my country is rich in water resources, so condensation is prone to occur in rainy weather in autumn and winter. The hazards of condensation in switchgear are extensive. First of all, the dew formed on the secondary terminal block in the terminal box mechanism box will cause corrosion to the metal conductive parts on the terminal block. If the corrosion is heavy or mixed with other impurities such as dust, it will easily cause AC and DC short circuit grounding. The stable operation of the subsystem has caused great harm. Secondly, the dew formed on the switch or knife switch operating mechanism will corrode the metal parts in the mechanism, affect the service life of the mechanism, and even cause the mechanism to jam due to corrosion, resulting in the mechanism not operating in place when the switch or knife switch is opened and closed. If the moving and static contacts of the switch are opened and closed slowly, it will cause a huge electric accident, especially when the switch has not been operated for a long time, the corrosion phenomenon will be more serious. Finally, the high-voltage room generally pays more attention to ventilation, so the indoor temperature and humidity are greatly affected by the outdoor environment. Condensation is also prone to occur in the indoor high-voltage switchgear. If there is dew on it, its insulation will be reduced, and it may even cause creepage or flashover This phenomenon seriously affects the normal operation of equipment, especially when some equipment is out of service, its internal temperature is lower, and it is easier to form condensation on its surface. At this time, accidents are extremely likely to occur once power is supplied.

Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

As shown in FIGS. 1 to 4 , a device for detecting temperature and humidity inside a switch cabinet 1 according to an embodiment of the present invention includes a switch cabinet 1 and a sensor 2 located in the switch cabinet 1 . The sensor 2 includes a temperature sensor and a humidity sensor. The temperature inside the switch cabinet 1 is detected by the temperature sensor, and the temperature value is transmitted to the display screen 5, and the humidity inside the switch cabinet 1 is detected by the humidity sensor, and the temperature value is transmitted to the display screen 5, and the display screen 5 is displayed in the form of The form displays the real-time temperature and humidity inside the switchgear 1. Relevant staff read the value from the display 5 at regular intervals and compare it with the critical value. When the vertical value is close to the critical value, the switchgear 1 is maintained to avoid condensation Phenomenon. The display screen 5 can also be connected to the Internet, and correspondingly, relevant staff can monitor online in real time.

A bracket 3 sliding in the switch cabinet 1 is installed in the switch cabinet 1. The bracket 3 is slidably connected with the switch cabinet 1. The inner wall of the switch cabinet 1 is cut to form a slideway 4. The end of the bracket 3 is located in the slideway 4. The bracket 3 slide along the slideway 4 in the switch cabinet 1. There are two slideways 4, and the slideways 4 are located at both ends of the bracket 3 respectively. The bracket 3 is provided with a seat body 6 sliding along the length direction of the bracket 3, the seat body 6 is slidingly connected with the bracket 3, the bracket 3 forms a protrusion 9 extending along the length direction of the bracket 3 by cutting, and the seat body 6 is processed by cutting A sliding groove 8 is formed to cooperate with the protrusion 9, and the protrusion 9 is located in the sliding groove 8 and guides the seat body 6 to slide. The width of the upper top surface of the chute 8 is greater than the width of the lower top surface, which is convenient for the seat body 6 to be installed on the support 3 and keep in contact with the support 3 under the action of gravity. The sensor 2 can not only slide on the bracket 3 along the bracket 3, but also slide along the slideway 4 following the bracket 3, so that the sensor 2 can adjust its position and can detect any position in the inner plane of the switch cabinet 1.
