1. The function is different: switchgear is a complete set of electrical switchgear and control equipment, it is used as a power center and the main distribution device, mainly to play the role of a switch on and off. And distribution cabinet is to plays the function of distribution of electrical energy, line overload, short circuit, leakage protection role.
What is the internal structure of the power distribution box and distribution cabinet? The most detailed explanation, learning collection essential!
“Distribution box”, also called distribution cabinet, is the collective name of the motor control center. A distribution box is according to the electrical wiring requirements of the switchgear, measuring instruments, protection appliances, and auxiliary equipment assembled in the enclosed or semi-enclosed metal cabinet or screen width, constituting a low-voltage power distribution device.
What is high-voltage switchgear equipment? High-voltage switchgear refers to the role of on-off, control or protection in the power generation, transmission, distribution, power conversion and consumption of the power system. Electrical products with voltage levels ranging from 3.6 kV to 550 kV, mainly including high-voltage circuit breakers, high-voltage isolation switches and grounding switches, high-voltage load switches, high-voltage automatic reclosers and sectioners, high-voltage operating mechanisms, high-voltage explosion-proof power distribution devices, and high-voltage Switch cabinets, etc.
Common Faults And Treatment Of High-Voltage Electrical Equipment
The focus is on the failures and solutions of 10kV circuit breakers (vacuum, sulfur hexafluoride), disconnectors, busbars, transformers, transformers, cables and arresters. Engineering and technical personnel can refer to this article to analyze and process the accidents of high-voltage electrical equipment to ensure the safe operation of electrical equipment, reduce the impact of accidents, prevent problems as much as possible, and eliminate accidents in the bud.
According to the regulations, the voltage above 250 volts is called high voltage. Here we are mainly talking about 10 kV complete sets of equipment: that is electrical switchgear, metering cabinets, capacitor cabinets, etc. It also includes incoming and outgoing wires and transformers.
