Description
Technical field
The invention belongs to breaker technical fields, are specifically exactly to be related to a kind of electromagnetic release.
Background technique
Breaker is divided into high-voltage circuitbreaker and low-voltage circuit breaker by its use scope.Low-voltage circuit breaker is also known as automatically switched,
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 protection, 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 does not need generally to become after disjunction fault current
More components have had been widely used.
Breaker realizes the protection feature needed for it by installation buckle releaser, its working principle is that: if working as control line
When short circuit current or electric shock leakage current over the ground having occurred in road, and reaching breaker protection class, the electronics of buckle releaser swashs
Magnetic coil produces contrary with permanent magnet after obtaining enough voltage in the original closed suction of buckle releaser and magnetic circuit
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 there is several defects once for existing electromagnetic release: (1) electromagnetic release overall volume is larger,
Keep electromagnetism leakage switch volume insufficient, winding displacement difficulty increases in leakage switch assembling process；(2) electromagnetic release assembles
In the process, it needs to fix permanent magnet by riveting process, working hour is caused to extend, while can also generate small bits in riveting process,
Influence electromagnetic performance: (3) electromagnetic tripping apparatus is when divide-shut brake, without buffering course, increases in the course of work to pole
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, leads to trip gear loss of excitation, directly affects the movement of earth leakage circuit-breaker, seriously
The safety of neighbouring equipment is injured, it is easy to cause fire；(5) magnetic system of existing electromagnetic release is held in the housing without positioning
Easy double swerve keeps acting characteristic inconsistent, and there are delivery strokes and the unstable risk of force value: (6) magnetic yoke and armature pole-face
Secondary reset is easy to happen relative displacement, and therefore air gap generates variation on joint surface, and electric leakage trip action value is caused to have biggish wave
It is dynamic.
