High-voltage circuit breakers play a controlling role in high-voltage circuits and are one of the important electrical components in high-voltage circuits. Circuit breakers are used to switch the circuit on and off during normal operation. The fault condition switches off the circuit quickly under the protection of the relay and the short-circuit current can be reliably connected under special conditions, such as when automatically reclosing to a faulty line. High-voltage circuit breakers in the normal or fault conditions connected to the high-voltage circuit or disconnect the special appliances. The working state of the circuit breaker (open or closed) is controlled by his actuator. High pressure switch, high voltage isolation switch and high voltage circuit breaker difference: 1, high-pressure load switch can be with load breaking, self-arc function, but its small breaking capacity is very small. 2, high-voltage isolation switch is generally not with the load off, there is no structure of the arc hood, but also to break off the load of high-voltage isolation switch, but the structure and load switch is different, relatively simple. 3, high-pressure load switch and high-voltage isolation switch, can form a significant disconnect, most high-voltage circuit breakers do not have isolation, there are a few high-voltage circuit breakers isolation. 4, high-voltage isolation switch does not have protection, high-voltage load switch protection is generally added fuse protection, only the fast off and over-current. 5, high-voltage circuit breaker breaking capacity can be done in the manufacturing process is high. Mainly rely on plus current transformer with secondary equipment to protect. Can have short circuit protection, overload protection, leakage protection and other functions. Extruded Graphite is a type of isostatic pressure graphite, which is currently produced by the extrusion molding method commonly used in most carbon and graphite products.
