Abstract
The utility model relates to a solid seal-type indoor high-voltage vacuum circuit breaker, comprising a cam and a buckle plate, wherein the cam is sleeved on a camshaft. The cam is passed by a connection plate, a main shaft, a main-shaft transmission crank arm, a transmission connection plate and a transmission crank arm and transmits energy to an insulation pull rod. The insulation pull rod is fixedly connected with a lower end of a conductive rod. One corner of the buckle plate is sleeved on a buckle plate shaft, another corner of the buckle plate is connected with a semi-shaft in a buckling manner and a third corner of the buckle plate is provided with a closing protection detent. An outer end of the closing protection detent can lean with a rotation end of the crank arm. The crank arm can rotate with rotation of the main shaft. The camshaft is driven to rotate the cam and enable the cam to push or leave the transmission arm by an energy storage mechanism, thereby driving the insulation pull rod connected with the transmission arm in a transmission manner to move upward and downward. Hand-operated brake-separating ejector rod and a brake-separating electromagnet are added to match with the semi-shaft and the buckle plate respectively, so that the closing protection detent and the semi-shaft are rapidly tripped and brake-separating operation is realized. The indoor high-voltage vacuum circuit breaker provided by the utility model has compact structure and high transmission energy efficiency ratio. An operation state of the breaker can be visually read.
