High-voltage switchgear is used in power system power generation, transmission, distribution, power conversion and consumption for on-off, control or protection.

The switchgear has the functions of overhead incoming and outgoing wires, cable incoming and outgoing wires, and bus connection. Mainly applicable to various places such as power plants, substations, petrochemicals, metallurgical steel rolling, light industry and textiles, factories and mining enterprises, residential quarters, and high-rise buildings.

my country began to introduce low-voltage power distribution cabinets in the 1980s, and gradually formed a complete set of facilities in the 1990s. By introducing advanced foreign equipment into China, great technological breakthroughs have been achieved. Judging from the imported foreign equipment, these equipment have advanced levels in equipment failure protection level, cabinet design, processing technology and intelligent switchgear. At the same time, it has also promoted major domestic enterprises to devote themselves to centralized monitoring, and more actively implement intelligent low-voltage complete sets of facilities and intelligent switches.

In terms of design, many manufacturers use CAD software for three-dimensional design. While calculating analysis, processing, database and design are effectively combined, the labor intensity of technicians is further reduced, and product reliability and design speed are improved. In terms of resistance to equipment failures, it is still technology research and development that restricts the failure of complete sets of equipment. In equipment development, limiting the duration of failures can effectively reduce arc damage. Once the arc fault occurs in the matching arc, the current can be cut off in a short time without affecting the drawer unit. This standard drawer unit has strong interchangeability, as long as the failed drawer is replaced, the normal operation of the entire system can be guaranteed

In addition, in the processing technology, the assembly technology of my country's low-voltage power distribution cabinet has also made great breakthroughs. At the same time, great achievements have been made in the cabinets without nut connections and the special-shaped busbars. In the cabinet connection, self-tapping screws are used to realize the non-nut connection of the cabinet assembly. The connection strength is high and the installation is convenient and reliable. The busbar system directly determines the electrical parameters of the low-voltage power distribution cabinet, such as temperature rise, short-circuit breaking capacity, and the way of incoming and outgoing wires, as well as the connection form of the bus.

In the 21st century, the rapid development of network technology has promoted the innovation and diversification of marketing methods. Among them, network marketing is the most valuable and popular form of consumption. This also promotes the accelerated development of all walks of life. This marketing model can help consumers save more energy, thereby reducing the possible waste of resources in the shopping process and avoiding merchants' manipulation of prices. Then the high and low voltage power distribution cabinets will also benefit, and the future development will be bright. With the continuous expansion of market demand, the industry of complete sets of high and low voltage power distribution cabinets, which are closely related to people's lives, has also developed rapidly.
