Abstract
This invention relates to one slant opening electrical release device against impact and vibration, which comprises iron core, reset spring, fix point, half axis, pull bar, top bar, spring, static iron core and coil, wherein, when the invention breaks the release device, it should give the machine one voltage signal that is coil 12 to get electricity to overcome the reset spring rotation and to drive half axis rotation to release pull bar.
Description
Technical field
The present invention relates to a kind of shock-resistant, vibration shunt release, belong to the low voltage electrical apparatus technology field.
Background technology
Shunt release is the release by voltage source excitation, and it is a kind of annex of circuit breaker, is used for the disjunction of far distance controlled circuit breaker.
But common shunt release does not possess under thump, vibration situation, and shunt release produces misoperation, the cisco unity malfunction of circuit breaker.
Summary of the invention
The object of the present invention is to provide a kind of shock-resistant, vibration shunt release, this shunt release can not produce misoperation under thump, vibration situation, and circuit breaker can operate as normal.
For achieving the above object, technical scheme of the present invention is: this shunt release comprises moving iron core, back-moving spring, fulcrum, semiaxis, pull bar, push rod, spring, static iron core, coil.
In the time will carrying out disjunction to the circuit breaker of equipped this patent shunt release, must give voltage signal of shunt release, be that coil 12 gets, moving iron core 1 around the 3 rotation adhesives of first fulcrum, and drives semiaxis 4 rotations under the effect that overcomes first back-moving spring 2, thereby pull bar 7 is threaded off, push rod 8 around 9 rotations of the 3rd fulcrum, reaches the purpose of shunt opening under the driving of spring 10, circuit breaker is disconnected.After coil 12 dead electricity, moving iron core I resets under 2 effects of first back-moving spring, and shunt release is in the shunt opening state.
By moving iron core 1, push rod 8 are carried out balanced design, mechanism is carried out the dynamic balancing design, make mechanism be in dynamic equilibrium state, under thump, vibration situation, mechanism does not produce misoperation.
Beneficial effect of the present invention: carry out balanced design by moving iron core, push rod to shunt release, make mechanism be in dynamic equilibrium state, under thump, vibration situation, mechanism does not produce misoperation, guaranteed that the circuit breaker in the electric power system normally moves, satisfied the naval vessel requirements of one's work.
Below in conjunction with drawings and Examples to the present invention's detailed explanation of making comparisons.
Description of drawings
Fig. 1 is a shunt release structural principle closure state schematic diagram of the present invention;
Fig. 2 is a shunt release structural principle shunt opening view of the present invention.
Embodiment
See figures.1.and.2, this is shunt release structure closure state of the present invention and shunt opening view.
As shown in the figure, the shunt release structure comprises moving iron core 1, first, second back-moving spring 2,6, first, second, third fulcrums 3,5,9, semiaxis 4, pull bar 7, push rod 8, spring I0, static iron core 11, coil 12.
When this shunt release structure disjunction state, in the time will carrying out disjunction, must give voltage signal of shunt release to the circuit breaker of equipped this patent shunt release, promptly coil 1; Electric, moving iron core I around the 3 rotation adhesives of first fulcrum, and drives semiaxis 4 rotations under the effect that overcomes first back-moving spring 2, thereby pull bar 7 is threaded off, push rod 8 around 9 rotations of the 3rd fulcrum, reaches the purpose of shunt opening under the driving of spring 10, circuit breaker is disconnected.Behind the coil losing electricity, moving I unshakable in one's determination resets under 2 effects of first back-moving spring, and shunt release is in the shunt opening state.
By moving iron core 1, push rod 8 are carried out balanced design, make mechanism be in dynamic equilibrium state, under thump, vibration situation, mechanism does not produce misoperation.
Though the present invention describes with reference to the above embodiments; but those of ordinary skill in the art; will be appreciated that above embodiment is used for illustrating the present invention; should understand and wherein can make variations and modifications and do not break away from the present invention in a broad sense; so be not as limitation of the invention; as long as in connotation scope of the present invention, to the variation of above-described embodiment, the protection range that distortion all will fall into claim of the present invention.
