Description

Technical Field

[0001] The utility model relates to the technical field of power equipment, in particular to an outdoor AC high-voltage vacuum circuit breaker. Background Art

[0002] Vacuum circuit breakers, named for their arc-extinguishing medium and the insulating medium in the contact gap after arc extinguishing, are both high vacuum. They are small, lightweight, suitable for frequent operation, and require no maintenance during arc extinguishing. They are widely used in distribution networks and can be used to protect and control electrical equipment in industrial and mining enterprises, power plants, and substations. They are particularly suitable for use in locations that require oil-free operation, low maintenance, and frequent operation. While existing outdoor high-voltage vacuum circuit breakers have to some extent addressed operational failures in harsh environmental conditions, they lack an effective solution for the impact of bird activity. Birds often rest on circuit breakers and even build nests, which can easily cause electric shocks to birds and affect their normal operation. Utility Model Content

The internal structures of the two installation boxes 501 are identically arranged.

[0028] like Figure 1 、 Figure 3 As shown, the sealed pole 4 includes an upper porcelain bottle 401 and a lower porcelain bottle 402. The bottom of the upper porcelain bottle 401 is connected to the top of the lower porcelain bottle 402 by fastening bolts, and the bottom end of the lower porcelain bottle 402 is connected to the top of the pole box 1 by fastening bolts. A vacuum arc chamber 403 is opened inside the upper porcelain bottle 401, and the inner cavity of the lower porcelain bottle 402 is provided with an insulating pull rod 405.
