AI Technical Summary

Technical Problem

Outdoor high-voltage AC vacuum circuit breakers need to be installed at high locations. When manually operating them, workers need to climb to high places to work, which is cumbersome and dangerous.

Method used

A circuit breaker system comprising a hook assembly, a pull rope assembly, and a drive structure was designed. The operating handle is lowered to an accessible height by a motor-driven pull rope, allowing operators to operate from a low position. The system is also designed to accommodate circuit breakers of different specifications by incorporating a limit structure.

Benefits of technology

It enables safe and convenient opening and closing operations without climbing, reducing operational risks and adapting to the installation requirements of different types of circuit breakers.

Abstract

The utility model discloses an outdoor column high -voltage ac vacuum circuit breaker belongs to circuit breaker technical field, including vacuum circuit breaker and the operation handle for controlling vacuum circuit breaker closing or opening of arrangement on vacuum circuit breaker, the pull -out opening structure of arrangement on vacuum circuit breaker for pulling operation handle and make it active. The utility model, when vacuum circuit breaker is installed to the use of outdoor column, if needing to carry out opening and closing operation, can through the opening corresponding motor to the winding pull cord, make the one end of pull cord to drop to the height of staff accessible, at this time, staff only needs to pull down pull cord, can through the hook to drive one end of operation handle to overturn to corresponding direction to the operation of opening and closing without climbing to high place can be carried out, and after the operation is completed, can control motor output end reverse rotation to re -winding pull cord to high place, avoid the pull cord of the mis -touch of the pull of the lower pedestrian.
