Waterproof outdoor power distribution cabinet with ventilation and heat dissipation functions

Abstract

The invention provides a waterproof outdoor power distribution cabinet with ventilation and heat dissipation functions, which comprises a machine body, the right end surface of the machine body is provided with a power distribution cavity with a rightward opening, the upper and lower wall surfaces of the right end of the power distribution cavity are hinged to an opening and closing door capable of being turned over, the opening and closing door can close the right end opening of the power distribution cavity, and the lower side of the machine body is provided with a ground. Lifting columns which are symmetrical left and right and extend upwards are fixedly arranged in ground corresponding to lower end face of machine body. According to the invention, the internal temperature of the powerdistribution cavity is sensed by utilizing the thermal expansion of gas, so that the on-off control of the driving motor is realized, and meanwhile, the shutter is opened to promote air circulation and accelerate the internal heat dissipation of the power distribution cavity, so that the heat dissipation efficiency of the power distribution cavity is improved, and the service life of the motor isprolonged. And meanwhile, the power distribution cabinet also has a function of detecting the water level, so that the power distribution cabinet can be lifted to a certain height in time, the electric leakage of the power distribution box caused by over-high water level is prevented, and the probability of accidents is effectively reduced.

Description

technical field [0001] The invention relates to the field of power distribution cabinets, in particular to an outdoor water-ingress-proof power distribution cabinet with ventilation and heat dissipation functions. Background technique [0002] In our daily life, power distribution cabinets are placed on both sides of the road. The power distribution cabinets can assemble various electrical equipment and electrical components such as switchgear, measuring instruments, protective appliances and auxiliary equipment in closed or semi-closed metal cabinets. Various electrical equipment may be installed in the electric cabinet, so when it is working, it will continue to generate heat. In addition, in relatively high-temperature outdoor areas or environments, direct sunlight is also the main factor that easily leads to internal overheating, which is likely to cause damage to electrical equipment. Most of the current power distribution cabinets are directly fixed on the ground, and ...

[0002] In our daily life, power distribution cabinets are placed on both sides of the road. The power distribution cabinets can assemble various electrical equipment and electrical components such as switchgear, measuring instruments, protective appliances and auxiliary equipment in closed or semi-closed metal cabinets. Various electrical equipment may be installed in the electric cabinet, so when it is working, it will continue to generate heat. In addition, in relatively high-temperature outdoor areas or environments, direct sunlight is also the main factor that easily leads to internal overheating, which is likely to cause damage to electrical equipment. Most of the current power distribution cabinets are directly fixed on the ground, and it is easy to form water accumulation in low-lying places, resulting in leakage of power distribution cabinets. There are still some defects in the existing power distribution cabinets. A ventilation and heat dissipation function described in the present invention The anti-water ingress outdoor power distribution cabinet can solve the above problems
