The high-voltage vacuum circuit breaker is named after its arc extinguishing medium and the insulating medium in the contact gap after the arc extinguishing are high vacuum; it has the advantages of small size, light weight, suitable for frequent operation, and no need for maintenance of arc extinguishing. Internet applications are more popular.
1. Wiring in front of the board
The front-board wiring method is the default wiring method of the circuit breaker. If the front-board wiring method is adopted, no special instructions are required. Before the circuit breaker is installed in the complete set of equipment, the user can directly connect the power line and load line on the connection board of the circuit breaker base, and fasten the wiring with screws.
Second, the wiring behind the board
The wiring behind the board means that when the circuit breaker is installed in the complete set of equipment, the connection plate on the base of the circuit breaker is connected to the power line and load line through the bolts of the mounting plate. Its biggest feature is that when the circuit breaker is replaced or repaired, there is no need to re-wire, only the front-stage power supply must be disconnected. Due to the special structure, the product has been equipped with special mounting plates and mounting screws and wiring screws according to the design requirements when leaving the factory. Special attention should be paid to the fact that the contact reliability of the large-capacity circuit breaker will directly affect the normal use of the circuit breaker. Therefore, attention must be paid to the installation and the installation must be carried out in strict accordance with the requirements of the manufacturer.
Three, plug-in wiring
Plug-in wiring refers to the installation of a mounting seat with six sockets on the installation board of the complete set of equipment, which is used in conjunction with the 6 sockets on the connection board of the circuit breaker. There are connecting plates on the surface of the mounting base or bolts behind the mounting base, and the mounting base is pre-connected with power and load lines. When in use, the user can directly insert the circuit breaker into the mounting base for use. If the circuit breaker is damaged, just pull it out and replace it. The replacement time is shorter than the wiring before and after the board, and it is convenient. However, the plug-in wiring circuit breaker requires a certain amount of manpower to plug and unplug, so the current plug-in products of various countries in the world have a maximum shell current of 400A.
Four, drawer type wiring
Drawer type wiring is generally used for the installation of universal circuit breakers. The in and out drawer of the circuit breaker is completed by the rocker rotating clockwise or counterclockwise. The plug-in structure is adopted in the main circuit and the secondary circuit, eliminating the need for fixed installation. The isolators can be used as one machine for two purposes, which improves the economy of use, increases safety and reliability, and also brings great convenience to operation and maintenance. The universal circuit breaker can adopt two fixed wiring methods of front (vertical) and rear (horizontal) wiring, and it can also use drawer wiring.
