In the second
A solenoid valve for a power circuit breaker, characterized in that a spring seat fixed to a yoke plate is provided with a gap adjustment means that can continuously change the gap length between the magnetic pole and the plunger. (2) In the solenoid valve described in claim 1 of the utility model registration claim, the gap adjustment means that can continuously change the gap length between the magnetic pole and the plunger is a screw provided in the spring seat in the axial direction of the plunger. A solenoid valve for a power circuit breaker, comprising a hole and a screw that is screwed into the screw hole and whose tip abuts the end surface of the plunger on the opposite side of the push pin.
