Description
Technical field
The present invention relates to field of circuit breakers, specifically a kind of circuit breaker tripping device.
Background technology
In order to make circuit-line safety, effectively prevent the generation of electricity consumption fire and the protection person and animal safety to electricity.The circuit breaker of control circuit circuit can be when circuit has very little electric leakage or shock current to take place, and cut-out control circuit fast and safely plays protection circuit safety and person poultry safety's effect.Its operation principle is; if in control circuit short circuit current or electric shock leakage current over the ground taken place; and when reaching the breaker protection grade; the electronics magnetizing coil of release is after obtaining enough voltage; in the adhesive magnetic circuit of the original sealing of release, produced the magnetic field opposite with the permanent magnet direction; thereby offset the magnetic field intensity that permanent magnet produces; the thrust spring that is in compressive state this moment discharges and ejects; push rod is released; the power that push rod is released triggers circuit breaker tripping and line disconnection, has protected the safety of circuit.When the arbitrary power line of circuit breaker disappearance appears or situation about disconnecting under; circuit just can not provide back work voltage to the control circuit board of circuit breaker; just because there be boost voltage can not work only according to the circuit breaker that the electronics magnetizing coil carries out circuit and occurrences in human life protection this moment, and lose defencive function.The existing circuit breaker release comprises function singleness in other words, and reliability and stability are poor.
Summary of the invention
Purpose of the present invention is for providing reliability and stability good circuit breaker tripping device.
The technical scheme that realizes the foregoing invention purpose is as follows:
The circuit breaker tripping device, comprise the tripping mechanism of magnetic force adhesive mechanism, thrust spring and push rod composition that permanent magnet and magnetic conduction part are formed, the action triggers mechanism that coil constitutes, wherein said magnetic conduction part comprises a yoke that takes the shape of the letter U substantially, the both sides of described U-shaped yoke are with a bobbin respectively, be tied with coil on each bobbin, two coils constitute electromagnetism magnetizing coil and the electronics magnetizing coil that works alone respectively.
The bottom of described U-shaped yoke is provided with a permanent magnet, upper end horizontally set one armature of described U-shaped yoke, the lower end of a push rod pass the hole at armature middle part, and the block at push rod middle part is stuck in the upper end of armature, the lower end of push rod is with a thrust spring, and the lower end of thrust spring connects a spring base.
Described spring base upper end has a projection, and this projection is plugged in the thrust spring.
Described circuit breaker tripping device also comprises a pedestal, and described magnetic force adhesive mechanism, tripping mechanism and action triggers mechanism all are arranged in the pedestal, have the spacing or positioner of part in the described pedestal.
Spacing or the positioner of described part comprises a limit sliding chutes along the pushrod movement direction.The effect of limit sliding chutes is that push rod is only moved along releasing the direction of regaining, and avoids being displaced sideways as far as possible.
Spacing or the positioner of described part comprises the bobbin positioning table.
The present invention adopts two electronics magnetizing coils that work alone respectively and electromagnetism magnetizing coil; the earth leakage circuit breaker that works independently with single magnetizing coil in the past relatively; aspect protective value, possessed dual protection, promoted the protection reliability and stability of circuit breaker.But also possess control circuit board by circuit breaker realize will be small the amplification of electric leakage shock current realize reliably protecting the time; also carry out reliably protecting simultaneously even the electric leakage electric shock accidents occurs taking place under the situation of phase shortage at circuit, effectively overcome the problem of existing breaker protection deficiency.Even this is because circuit breaker can not start the Electronic Protection function because there being boost voltage; circuit breaker can also realize not having the boost voltage defencive function by the electromagnetism magnetizing coil; principle is that short circuit current or electric shock leakage current over the ground taken place in the control circuit; and when reaching the breaker protection grade; electric leakage signal also can directly be transported to the electromagnetism magnetizing coil of release at once simultaneously; the electric leakage signal in this loop does not pass through the control circuit board of circuit breaker; start protection and need not any external boost voltage; the electromagnetism magnetizing coil is after obtaining enough transformer induced voltage; in the adhesive magnetic circuit of the original sealing of release, produced the magnetic field opposite with the permanent magnet direction; thereby offset the magnetic field intensity that permanent magnet produces; the thrust spring that is in compressive state this moment discharges and ejects; push rod is released; the power that push rod is released triggers circuit breaker tripping and line disconnection, has protected the safety of circuit.
