specific Embodiment 1

[0022] Specific embodiment 1, with reference to figure 1 , figure 2 , image 3

[0023] The electrical cabinet with a monitoring system includes a telescopic box 1 and an electrical cabinet body 16, the telescopic box 1 is fixedly installed on the left side of the electrical cabinet body 16, the left side of the inner wall of the telescopic box 1 is fixedly connected with a rotating motor 2, and the rotating motor 2 The output end is rotatably connected with a rotating rod 3, the top of the rotating rod 3 is rotatably connected with a rotating connecting rod 4, and the right end of the rotating connecting rod 4 is rotatably connected with a horizontal plate 5, and the front side of the horizontal plate 5 is provided with a transverse groove 6, and the horizontal plate The right side of 5 is fixedly connected with connection block 7, and the right side of connection block 7 is provided with ball groove 8, and the inside of ball groove 8 is connected with the ball 9 that is c...

specific Embodiment 2

[0024] Specific embodiment 2, with reference to Figure 4

[0025] The difference between specific embodiment 2 and specific embodiment 1 is that the inner wall of the electrical cabinet body 16 is also provided with ventilation pipes 21 extending up and down. Shape, each ventilation pipe 21 is positioned at the mouth of the nozzle below the different heights but all towards the inner side of the electrical cabinet body 16. Preferably, the inner diameter of the ventilation pipe decreases gradually from top to bottom.

specific Embodiment 3

[0026] Specific embodiment 3, with reference to Figure 5

[0027] The difference between embodiment 2 and embodiment 1 is that at least three support plates 22 for fixing circuit boards are arranged in the electrical cabinet body (16), and each support plate 22 is located in the vertical direction and parallel to each other. The support plate is preferably arranged in the left-right direction. At this time, it is not necessary to set up a ventilation pipe separately.

Abstract

The invention relates to an electrical cabinet with a monitoring system. The electrical cabinet comprises an electrical cabinet body, a temperature detection system and a cooling system, and is characterized in that the cooling system comprises a telescopic box, the telescopic box is fixedly mounted on the left side of the electrical cabinet body, and a rotating motor is fixedly connected to the left side of the inner wall of the telescopic box; the control signal input end of the rotating motor is connected with the signal output end of the temperature detection system; the cooling system further comprises a fan installed at the top of the electrical cabinet body and an air bellow located in the electrical cabinet; the air outlet of the fan communicates with an air inlet of the air box; and a rotating shaft of the rotating motor is connected with the bellows through a transmission system and can drive the bellows to rotate. When the temperature detection system detects that the temperature of a component in the electrical cabinet body is higher than a preset value, a rotating fan is controlled to be started, the fan blows air into the electrical cabinet body through the hose and the air bellow, and the air flowing degree in the electrical cabinet body is increased, so the temperature of the component is taken away, and the component is restored to a proper temperature range as soon as possible.

Description

technical field [0001] The invention relates to the field of power systems, in particular to electrical cabinets. Background technique [0002] The electrical cabinet is a cabinet made of steel to protect the normal operation of components. The materials for making electrical cabinets are generally divided into two types: hot-rolled steel plates and cold-rolled steel plates. Compared with hot-rolled steel sheets, cold-rolled steel sheets are softer and more suitable for the production of electrical cabinets. Electrical cabinets are widely used in chemical industry, environmental protection industry, power system, metallurgical system, industry, nuclear power industry, fire safety monitoring, transportation industry, etc. The electronic components in the electrical cabinet need to be cooled, and the existing workflow is large and The desired effect cannot be achieved, and the uneven cooling and excessive cooling speed in the cooling process will cause local overheating and ...
