Embodiment 1

[0027] This embodiment is basically as figure 1Shown: a low-voltage switchgear cabinet body, including a cabinet body 10 and a drawer 50 that can be drawn relative to the cabinet body 10. The cabinet body 10 is obtained by processing aluminum-zinc coated plates, which have high hardness and are not easily deformed. , has the characteristics of corrosion resistance and oxidation resistance, and it is more suitable to process the cabinet body 10 with an aluminum-zinc coated plate. The side wall of the cabinet body 10 is provided with a heat dissipation port 11, the outer wall of the cabinet body 10 is welded with a buffer chamber 20 opposite to the heat dissipation port 11, and the side wall of the buffer chamber 20 opposite to the heat dissipation port 11 is provided with a heat dissipation hole 21 . The bottom of the buffer chamber 20 is inclined downward to the side away from the cabinet body 10. After external dust and rainwater enter the buffer chamber 20, it will move awa...

Embodiment 2

[0031] The difference between this embodiment and Embodiment 1 is that: figure 2 , 3 As shown, a piston cylinder 60 is fixedly installed on both sides of the rear side wall of the drawer 50 , and one end of the piston cylinder 60 close to the drawer 50 is opened. A piston 61 is slidably and sealedly connected to the piston cylinder 60, and a support rod 62 passing through the piston cylinder 60 and capable of sealing connection with the piston cylinder 60 is fixed on the piston 61, and a mounting seat 63 located outside the piston cylinder 60 is welded on the support rod 62 , one of the mounting bases 63 is fixedly installed with an incoming moving contact 64, and the other mounting base 63 is fixedly installing an outgoing moving contact 65. A sleeve 70 is also fixed on the rear side wall of the drawer 50. The sleeve 70 is fixed between the two piston cylinders 60. The end of the sleeve 70 is open away from the drawer 50. The sleeve 70 is filled with hydraulic oil. A seali...

Abstract

The invention belongs to the technical field of electrical equipment, and particularly relates to a low-voltage switch cabinet, which comprises a cabinet body and a drawer capable of being drawn relative to the cabinet body, wherein a temperature tester and an alarm unit are arranged in the cabinet body, an air bag layer is arranged in the cabinet body, a first electromagnetic valve is arranged onthe air bag layer, the exterior of the cabinet body is provided with a heat dissipation chamber which can be communicated with the interior of the cabinet body, the interior of the heat dissipation chamber is provided with a heat dissipation fan, a liquid nitrogen bottle and a controller, the liquid nitrogen bottle is connected with an exhaust pipe capable of being communicated with the air bag layer, the exhaust pipe is provided with a second electromagnetic valve, and the controller is in communication connection with the temperature tester, the first electromagnetic valve and the second electromagnetic valve. By using the technical scheme, the problem that the internal structure of the switch cabinet cannot effectively deal with the abnormal heating of the switch cabinet can be effectively solved.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and in particular relates to a low-voltage switch cabinet body. Background technique [0002] Low-voltage switchgear is suitable for power plants, petroleum, chemical industry, metallurgy, textiles, high-rise buildings and other industries, as power transmission, power distribution and power conversion. As an important equipment for power distribution, low-voltage switchgear plays an important role in modern distribution network and engineering construction. [0003] There are a variety of electrical components inside the low-voltage switchgear that will generate a lot of heat when they work, causing the temperature inside the low-voltage switchgear to rise. When the ambient temperature is high, it is not conducive to the work of the internal electrical components, and sometimes even burns out the electrical components. In view of the above problems, in the prior art, a cooling devi...
