Abstract
The utility model discloses an indoor high-voltage AC vacuum circuit breaker. The breaker comprises a vacuum post, a breaker frame, an operation mechanism, an operation panel, a main shaft, a transmission system and a chassis vehicle. The breaker frame is arranged on the chassis vehicle. The vacuum post, the operation mechanism, the main shaft and the transmission system are respectively disposed on the breaker frame. The operation mechanism is connected with the main shaft via the transmission system. The operation panel is connected with the operation mechanism. An inclusive open composite insulating structure is adopted for insulation of the breaker so as to be more beneficial to the high-rated current scheme. Air insulation is employed to be main insulation, thereby saving materials and reducing costs. The breaker is suitable for frequent operation requiring rated operational currents or suitable for places where short circuit currents are on and off many times, and can meet demands of users. The mechanism has an open output structure and can easily match the breaker, thereby improving the production efficiency. During energy storage, the breaker can be operated electrically or manually and is equipped with an anti-reversal and mechanical clutch device. Moreover, the breaker is stable in running, low in noise and high in efficiency.
