Integrated vacuum circuit breaker

Abstract

The utility model relates to the field of vacuum circuit breakers, and discloses an integrated vacuum circuit breaker, which comprises a vacuum arc-extinguishing chamber, the vacuum arc-extinguishing chamber is in bolted connection with a base, the vacuum arc-extinguishing chamber is fixedly connected with a combined mutual inductor, the combined mutual inductor is connected with the base through a line, the vacuum arc-extinguishing chamber is provided with a snap ring I, and the snap ring I is provided with a snap ring II. The first clamping ring is hinged to a second clamping ring, and a bolt is arranged between the first clamping ring and the second clamping ring. According to the utility model, through the cooperation of the fastener, the push rod, the first connecting rod, the baffle plate, the first spring and the arc-shaped reinforcing member, the vacuum arc-extinguishing chamber and the combined type mutual inductor are fixed tightly and are more convenient to mount and dismount, and through the slide block, the vertical column, the upper stop block, the third spring, the lower stop block and the fourth spring, the vacuum arc-extinguishing chamber and the combined type mutual inductor are fixed tightly; according to the utility model, the vibration of the installation position and the outside can be offset, and the problems that the circuit breaker is not stable enough and the working stability is poor can be prevented.
