Safe and reliable low-voltage power distribution device for electrical network

Abstract

The invention relates to a safe and reliable low-voltage power distribution device for an electrical network. The low-voltage power distribution device comprises a base, a mounting block, a cabinet body, a cabinet door, two supporting mechanisms and two ventilation mechanisms, each supporting mechanism comprises a supporting box, a supporting frame, a lifting component and a supporting plate; eachlifting component comprises a driving unit, a fixed block, a translation block, a telescopic frame, a sliding block and a sliding frame; each ventilation mechanism comprises a ventilation pipe, a transverse pipe and two ventilation components; and air valves are arranged in ventilation pipes, and each ventilation component comprises a vertical pipe, a sealing unit and a ventilation unit. According to the safe and reliable low-voltage power distribution device, air inside and outside the cabinet body can be exchanged conveniently through the ventilation mechanisms for cooling and heat dissipation, the air entering the cabinet body can be dust prevention and drying to avoid that the humidity in the cabinet body is too large, the supporting mechanisms can support the cabinet body to move upwards, the cabinet body is driven to be away from accumulated water when waterlogging occurs, damage caused by water immersion in the cabinet body is avoided, and therefore, the safety coefficient andthe practicability of the low-voltage power distribution cabinet are improved.

Description

technical field [0001] The invention relates to the field of electrical equipment, in particular to a safe and reliable low-voltage distribution device for electrical networks. Background technique [0002] The low-voltage power distribution cabinet is the final equipment in the low-voltage power distribution system. The power distribution cabinet is used in the places where the load is relatively dispersed and there are many circuits; the motor control center is used in the occasions where the load is concentrated and there are many circuits. They distribute the electric energy of a certain circuit of the upper-level power distribution equipment to the nearby load. Protection, Control and Surveillance.

AI Technical Summary

Problems solved by technology

[0003] When some existing low-voltage power distribution cabinets are installed outdoors, most of them have a low safety factor, especially in some rainy and humid weather. Due to the high air humidity in rainy weather, the power distribution cabinets perform ventilation and heat dissipation at the same time. It is easy to introduce moisture in the air into the cabinet. When the humidity in the cabinet is high, it is easy to cause short-circuit device failure and damage. Not only that, the existing low-voltage power distribution cabinets are installed with fixed generators. In the case of waterlogging, the rainwater cannot be discharged in time. If the water level is too high, it may cause accumulated water to soak into the power distribution cabinet, which will affect the use of equipment and lead to failure and damage of the power distribution cabinet, thereby reducing the practicability of the existing low-voltage power distribution cabinet.
