Description

Technical Field

[0001] The utility model relates to the technical field of isolation knife seats, in particular to an isolation knife seat for an outdoor high-voltage vacuum circuit breaker. Background Art

[0002] Vacuum circuit breaker is a kind of power equipment, mainly used for circuit protection and control, especially in industrial and mining enterprises, power stations and substations. The internal structure of vacuum circuit breaker contains a vacuum chamber, which is used for arc extinguishing, that is, quickly extinguishing the arc when the circuit is disconnected. Its working principle is that when the moving and static contacts are opened under the action of the operating mechanism, an arc is generated between the contacts, and the contact surface evaporates steam at high temperature. The isolation knife holder is one of the accessories of outdoor vacuum circuit breakers. At present, there are many kinds of isolation knife holders suitable for outdoor high-voltage vacuum circuit breakers on the market, but there are still some disadvantages;

[0003] For example, in actual use, the isolation knife holder of a general outdoor high-voltage vacuum circuit breaker is connected through a flat wiring part, and the copper terminal is often blocked. At the same time, because the isolation knife holder is usually installed outdoors, it is easy to encounter strong winds outdoors, which can easily cause the connected wires to fall off. In addition, the isolation knife holder is prone to some birds flying on it outdoors, which will cause serious hidden dangers. Secondly, the isolation knife holder generally has a wiring part and the left side of the wiring part fixed together and cannot be disassembled. Once a problem occurs with the isolation knife holder, it needs to be disassembled and replaced as a whole, which will be time-consuming. Therefore, we propose an outdoor high-voltage vacuum circuit breaker isolation knife holder to solve the above problems. Utility Model Content

[0004] The utility model aims to provide an outdoor high-voltage vacuum circuit breaker isolation knife seat to solve the problem that the current outdoor high-voltage vacuum circuit breaker isolation knife seat proposed in the above background technology is that the wiring is carried out flatly through the wiring part, and the copper terminal is often blocked.
