Abstract
The invention discloses a switch-on contactor. The switch-on contactor comprises a static iron core, a coil surrounding the static iron core, a moving iron core, a linkage rod, a normally opened contact, a first fixing plate, a second fixing plate, a pinch-off plate, a base, a first spring and a second spring, wherein the base is fixed on the first fixing plate, and the moving iron core is hinged with the base; a first end of the moving iron core is positioned below the static iron core; the linkage rod is connected with the normally opened contact and a second end of the moving iron core; meanwhile, the linkage rod is connected with the second spring; one end of the second spring pushes the second fixing plate, and the other end of the second spring pushes the pinch-off plate; one end of the first spring pushes the first fixing plate, and the other end of the first spring is fixed on the bottom of a first end of the moving iron core. The switch-on contactor provided by the invention solves the defect that a clamping spring of a traditional contactor is invalid, and the moving iron core cannot return, and forces the moving iron core to return so as to cut off high-voltage power supply.
Description
Technical field
The present invention relates to a kind of closing contactor.
Background technology
Along with the continuous enhancing of electric power enterprise service awareness, also more and more higher to the requirement of self power supply reliability.What 35kV line switching adopted is electromagnetic operating mechanism, in switch transmission in recent years and deciliter test, repeatedly occur that switch closes a floodgate, the unsuccessful situation of reclosing with burning the anomalies such as closing coil, combined floodgate fuse, this has brought hidden danger to reliability and equipment safety operation of power supply.Wherein: when separating brake iron core returns, bite, the spacing jump ring tension of contact post etc. are that switch transmission divides, closes the abnormal main cause of closing a floodgate in test.
Summary of the invention
The object of the present invention is to provide a kind of closing contactor, solve traditional contactor and lost efficacy and moved the defect that iron core can not return at jump ring, thereby force moving iron core to return to cutoff high power supply.
The technical scheme that realizes above-mentioned purpose is:
A closing contactor, comprises static iron core, the coil around static iron core, moving iron core, gangbar, normally opened contact, the first fixed head, the second fixed head, pinching plate, pedestal, the first spring and the second spring, wherein:
Described pedestal is fixed on described the first fixed head;
Described moving iron core is hinged on described pedestal, and the first end of this moving iron core is positioned at described static iron core below;
Described gangbar connects the second end of described normally opened contact and described moving iron core, and this gangbar and described the second spring join simultaneously; Described second spring one end pushes against described the second fixed head, and the other end pushes against described pinching plate;
Described first spring one end pushes against described the first fixed head, and the other end is fixed on the bottom of described moving iron core first end.
Above-mentioned closing contactor, wherein, described normally opened contact external high voltage power supply.
The invention has the beneficial effects as follows: the present invention arranges by simple spring, when the spring failure originally resetting for normally opened contact, force moving iron core to return, normally opened contact is resetted, thus cutoff high power supply.
Accompanying drawing explanation
Fig. 1 is the structure chart of closing contactor of the present invention.
Embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
Refer to Fig. 1, closing contactor of the present invention, comprise static iron core 2, the coil 1 around static iron core, moving iron core 3, gangbar 10, normally opened contact K, the first fixed head 4, the second fixed head 7, pinching plate 9, pedestal 6, the first spring 5 and the second spring 8, wherein:
Pedestal 6 is fixed on the first fixed head 4; Moving iron core 3 is hinged on pedestal 6, thereby take pedestal as the swing of fulcrum two ends, and the first end of this moving iron core 3 is positioned at the below of static iron core 2; First spring 5 one end push against the first fixed head 4, and the other end is fixed on the bottom of moving iron core 3 first ends; Coil 1 electric after, hold moving iron core 3, moving iron core 3 first ends upwards swing, and pull the first spring 5 to stretch;
Gangbar 10 connects the second end of normally opened contact K and moving iron core 3, and this gangbar 10 and the second spring 8 join simultaneously; Second spring 8 one end push against the second fixed head 7, other end pushing and pressing pinching plate 9; Moving iron core 3 second ends are to lower swing, and gangbar 10 pulls normally opened contact K closure to compress the second spring 8 simultaneously, normally opened contact K external high voltage power supply, power supply.After coil 1 dead electricity, if the second spring 8 lost efficacy, if do not had in the situation of the first spring 5, probably moving iron core 3 can return, and normally opened contact K is always closed, can bring great potential safety hazard.Therefore, the first spring 5 worked when the second spring 8 loses efficacy, and pulled moving iron core 3 returns, thereby drove normally opened contact K to open.
Above embodiment is used for illustrative purposes only, but not limitation of the present invention, person skilled in the relevant technique, without departing from the spirit and scope of the present invention, can also make various conversion or modification, therefore all technical schemes that are equal to also should belong to category of the present invention, should be limited by each claim.
Claims (2)
