Magnetic field to counteract permanent magnet generation magnetic field strength, be now in compressive state thrust spring release and pop up,
Push rod is shifted onto, push rod release power triggering shunt release and line disconnection, protect line security.The buckle releaser course of work
In be using electromagnet principle realize short circuit or earth leakage protective.Electromagnetic leakage protective device is because stable and reliable in work, tripping is special
Property many advantages, such as not influenced by network voltage and be widely used, the core devices of electromagnetic leakage protective device are that electromagnetism is de-
Device is detained, the magnetic parameter of magnetictrip directly decides the power of earth leakage protective characteristic, therefore magnetictrip tripping is special
Property stabilization shape for breaker quality it is most important.
But in the magnetic structure of current magnetictrip, need that manually the permanent magnet in magnetic circuit is repeated mostly
Fill demagnetization operation.And fill demagnetization and cannot keep its consistency and taken a long time in technique, permanent magnet performance also cannot keep surely
It is fixed, so that buckle releaser is had the risk of loss of excitation.Once and buckle releaser loss of excitation, earth leakage circuit-breaker just can not to its relevant device etc. into
Row safeguard protection seriously jeopardizes the safety of surrounding devices, personnel, easy to cause fire.
