Description
Technical field
The invention belongs to breaker technical fields, are exactly specifically to be related to a kind of electromagnetic release.
Background technology
Breaker is divided into high-voltage circuitbreaker and low-voltage circuit breaker by its use scope.Low-voltage circuit breaker is also known as automatic switch,
It is commonly called as " air switch " and also refers to low-voltage circuit breaker, it is a kind of existing manual switch effect, and can carry out decompression automatically, owe
The electric appliance of pressure, overload and short-circuit protection.It can be used to distribute electric energy, infrequently start asynchronous motor, to power circuit and
The implementations such as motor protect, when they occur it is serious overload or short circuit and it is under-voltage when failures when can automatic shutdown circuit,
Function is equivalent to Fuse switch and crosses the combination of underheat relay etc., and need not generally become after disjunction fault current
More parts have had been widely used.
Breaker realizes the protection feature needed for it by installing buckle releaser, and operation principle is：If work as control line
When short circuit current flow over the ground or electric shock leakage current having occurred in road, and reaching breaker protection class, the electronics of buckle releaser swashs
It suction that magnetic coil was originally closed after enough voltage is obtained in buckle releaser and is generated in magnetic circuit opposite with permanent magnet direction
Magnetic field so as to counteract permanent magnet generation magnetic field intensity, 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 of stable and reliable in work, dropout spy
Many advantages, such as property influences from network voltage and be widely used, the core devices of electromagnetic leakage protective device are that electromagnetism takes off
Device is detained, the magnetic parameter of magnetictrip directly decides the power of earth leakage protective characteristic, therefore magnetictrip dropout is special
Property stabilization shape for breaker quality it is most important.
But there is several defects once for existing electromagnetic release：(1) electromagnetic release overall volume is larger,
Make electromagnetism leakage switch volume insufficient, winding displacement difficulty increases in leakage switch assembling process；(2) electromagnetic release assembles
In the process, it is necessary to fix permanent magnet by riveting process, man-hour is caused to extend, while small bits can be also generated in riveting process,
Influence electromagnetic performance：(3) electromagnetic tripping apparatus, without buffering course, is increased in the course of work to pole when divide-shut brake
The impact in face reduces the service life and reliability of product：(4) existing electromagnetic tripping apparatus take up and down buckle-type into
Row sealing, gap is larger, is easily accessible dust, causes trip gear loss of excitation, directly affects the action of earth leakage circuit-breaker, seriously
Injure the safety of neighbouring equipment, fire hazardous；(5) magnetic system of existing electromagnetic release is held in the housing without positioning
Easy double swerve makes acting characteristic inconsistent, and there are delivery strokes and the unstable risk of force value：(6) yoke and armature pole-face
Secondary reset is easy to occur relative displacement, and therefore air gap generates variation on composition surface, and electric leakage trip action value is caused to have larger ripple
It is dynamic.
