Description
Technical field
The invention belongs to breaker technical fields, are exactly specifically to be related to a kind of electromagnetic type trip gear.
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 are protected, when serious overload or short circuit and the failures such as under-voltage occurs in they 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 that the protection feature needed for it, operation principle be by installing buckle releaser：If working as control line
When short circuit current over the ground or electric shock leakage current having occurred in road, and reaching breaker protection class, the electronics of buckle releaser swashs
Magnetic coil produces opposite with permanent magnet direction after obtaining enough voltage in the original closed suction of buckle releaser and magnetic circuit
Magnetic field 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 stable and reliable in work, thread off spy
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 dropout is special
Property stabilization shape for breaker quality it is most important.
But there is several defects once for existing electromagnetic type trip gear：(1) electromagnetic type trip gear overall volume

It sets in assembling process, needs to make permanent magnet fix by riveting process, working hour is caused to extend, while also will produce in riveting process
Small bits, influence electromagnetic performance：(3) electromagnetic tripping apparatus, without buffering course, increases in the course of work when divide-shut brake
Impact to pole-face reduces the service life and reliability of product：(4) existing electromagnetic tripping apparatus takes buckle up and down
Formula is sealed, and gap is larger, is easily accessible dust, leads to 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 type trip gear is in the housing without fixed
Position is easy double swerve, keeps acting characteristic inconsistent, there are delivery strokes and the unstable risk of force value：(6) yoke and armature
The secondary reset of pole-face is easy to happen relative displacement, and therefore air gap generates variation on joint surface, causes electric leakage trip action value to have larger
Fluctuation.
