Description
Technical field
The present invention relates to a kind of locker, be specifically related to a kind of locker of electromagnetic switch.
Background technology
Electromagnetic switch is a kind of to power supply unit, supply line's enforcement on-off function device, because of advantages such as it is simple in structure, automatic power transmissions, not only can be used as circuit breaker but also can be used as residual current circuit breaker or automatic phase diverter switch.
In use, during due to its work, coil, all the time in "on" position, if the voltage of electrical network is high, easily burns coil to electromagnetic switch, if voltage is low, adhesive maintenance energy declines and easily burns contact, and causes switch fault.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: provide a kind of and can overcome above-mentioned defect, can auto-breaking, and expert's dynamic circuit breaker electricity again, improves the locker of the electromagnetic switch of service life of equipment and dependability.
The technical solution adopted for the present invention to solve the technical problems is: the locker of described electromagnetic switch, comprise the moving crane span structure and the adhesive electromagnet that are arranged in housing, the setting corresponding to moving crane span structure of adhesive electromagnet, it is characterized in that: on housing, be provided with locker, one end of moving crane span structure bottom armature is bent to form latch hook, and latch hook is corresponding with locker.
Described locker comprises installing rack, release electromagnet, catch, hand lever and inserted link, installing rack is fixed in housing, release electromagnet is arranged on one end of installing rack, the moving iron core of release electromagnet is connected with catch, catch connects inserted link, and inserted link is corresponding with latch hook, and the position corresponding with catch, the top of installing rack is provided with hand lever, the bottom of hand lever contacts with catch, and the first half cover of hand lever has hand lever spring.Hand lever spring conveniently makes hand lever reply.
On the moving iron core of described release electromagnet, cover has pagoda spring.
On described installing rack, be provided with spacing preiection, the position of spacing preiection is corresponding with the position of inserted link.Spacing preiection plays the effect to inserted link limited support, facilitates the location of inserted link, and avoids occurring botching routines, and improves job stability.
Described spacing preiection place is coated with circle wheel or bearing.Circle wheel or bearing directly contact with inserted link, reduce friction and improve comfort and useful life.
During use, starting relay is controlled the energising of adhesive electromagnet, crane span structure is moved down and adhesive electromagnetic actuation, and then make the dynamic and static closing of contact of earth leakage protective device.Moving crane span structure is its bottom armature extruding inserted link in folding process, and first inserted link pushes pagoda spring and retreat, and when latch hook moves down into behind the position of inserted link, pagoda spring is released inserted link makes inserted link insertion latch hook complete the locking to moving crane span structure.Now make the power-off of adhesive electromagnet, under the effect of inserted link and latch hook, moving crane span structure cannot on move, switch is all the time in "on" position.
During disjunction, release electromagnet energising action drives its moving iron core to move backward, and moving iron core drives inserted link to retreat by catch, and inserted link is separated with latch hook, and moving crane span structure moves upward under the effect of housing spring, drives moving contact separated with fixed contact.While needing manual separation, move hand lever, hand lever compressing catch moves backward, and it is separated with latch hook that catch drives inserted link to retreat, and moving crane span structure moves upward under the effect of housing spring, realizes disjunction.In the situation that realizing separation automatically, can realize manual separation again.
The beneficial effect that the present invention has is: after moving crane span structure and electromagnetic switch locking, can realize coil no power and just can guarantee steady closure, the energy that avoids waste, the useful life of improving product.By the setting of hand lever, automatic disjunction can not only be completed and manual disjunction can also be completed, more meet safety standard, improve safety in utilization.
