The movement of row divide-shut brake, since kinematic link is when being swung, can cause certain collision impact to the strut porcelain bushing of breaker,
It in the presence of the security risk of damage insulator, and swings for a long time, will lead to the indoor contact of arc extinguishing and contraposition deviation occur, influence
Power supply effect;
2, the sulfur hexafluoride in existing outdoor high-voltage sulfur hexafluoride circuit breaker can liquefy when encountering low temperature, cause
Sulfur hexafluoride gas-insulating ability and arc extinguishing ability decline to a great extent, when sulfur hexafluoride air pressure drop is down to the locking pressure of breaker
When, breaker can not work normally, and will lead to large-area power-cuts when serious, although existing outdoor high-voltage sulfur hexafluoride circuit breaker
Minority is mounted with heating device, but heating effect is undesirable, not can guarantee the normal work of sulfur hexafluoride, to the reality of breaker
