GGD alternating current low-voltage distribution cabinet

Abstract

The invention discloses a GGD alternating current low-voltage power distribution cabinet, comprising a cabinet body, wherein a cabinet door is arranged on the front end face of the cabinet body, a display screen and an observation window are arranged in the middle of the upper part of the cabinet door, side cabinet doors are arranged on the left and right sides of the cabinet body, vent holes areformed in the upper parts of the two side cabinet doors, the two side cabinet doors are connected with the rear end face of the cabinet body through hinges, a power device is installed at the rear lower part of the cabinet body, a base is arranged at the bottom of the cabinet body, the base is fixedly connected with the cabinet body via bolts, and a cooling fan and ventilation holes are arranged on a bottom plate of the cabinet body; the power device is installed on the right of the base, a temperature sensor is arranged in front of the base, a temperature sensing box is arranged on the rightof the temperature sensor, a singlechip and an information transmission unit are installed in the temperature sensing box, magnets are embedded into the inner surfaces of the two side cabinet doors, metal bars are arranged at the positions, corresponding to the magnets, of the cabinet body, and the temperature sensor can detect the temperature inside the cabinet body in real time. The setting of the cooling fan can accelerate the dissipation of heat inside the cabinet body; a filter screen is arranged at the air inlet of the fan to prevent sundries from entering the cabinet body; and the setting of the side cabinet doors enlarges the working space, so that not only is the working efficiency improved, but also the working comfort of staffs is increased.

Description

technical field [0001] The invention is a GGD type low-voltage AC power distribution cabinet, which belongs to the field of electrical equipment. Background technique [0002] GGD type AC low-voltage power distribution cabinet is suitable for power distribution systems of power users such as power plants, substations, factories and mines, etc., with AC 50Hz, rated working voltage 380V, and rated working current up to 3150A. It is used as power conversion for power, lighting and power distribution equipment. distribution and control purposes. GGD type AC low-voltage power distribution cabinet is based on the requirements of the Ministry of Energy's superiors and the majority of power users and design departments. It is safe, economical, reasonable and reliable. A new type of low-voltage power distribution cabinet designed in principle, the product has high breaking capacity and good dynamic and thermal stability. The electrical scheme is flexible, the combination is conveni...

AI Technical Summary

Problems solved by technology

As a replacement product of low-voltage switchgear, it is installed indoors and the altitude of the place of use can reach 2000m. However, in the existing technology, when using the power distribution cabinet to install electrical lines and equipment, because the internal space is small , It is very difficult to operate, which seriously affects the work efficiency. The current GGD type AC low-voltage power distribution cabinet cannot observe the temperature, and the heat dissipation performance is also very poor, so a GGD type low-voltage AC power distribution cabinet is needed to solve the above problems
