Abstract
The utility model discloses a take high -voltage direct -current relay of auxiliary switch device, include and continue electric outer casing and locate this interior moving contact, static contact of electric outer casing then to and the drive this moving contact up -and -down motion with the transfer line of static contact intercommunication and disconnection, then the electric outer casing bottom is located the transfer line below is equipped with a button switch, can press this button switch during the transfer line up -and -down motion simultaneously makes this button switch be in disconnection or closed. This take high -voltage direct -current relay of auxiliary switch device simple structure is through the break -make state of button switch feedback relay, button switch is very little to relay influence itself, does not occupy unnecessary space again, guarantees the relay simultaneously and normally works, button switch is not influenced by relay heavy current arc extinguishing can, and mechanical durability is long.
Description
Technical field
This utility model relates to a kind of HVDC relay, particularly relates to the HVDC relay of a kind of band auxiliary switchgear.
Background technology
Conventional HVDC relay typically without auxiliary switch, thus cannot the duty of verification relay in real time, if it occur that fault then cannot be fed back in time.In order to overcome this defect, people start to expect that arrange auxiliary switch on relay is tracked feedback to the opening and closing of relay.But existing auxiliary switchgear structure is the most relative complex, not only increases manufacturing cost, and takies larger space, is unfavorable for the miniaturization of relay, and additionally reliability is the highest.
Summary of the invention
In order to overcome drawbacks described above, this utility model provides the HVDC relay of a kind of band auxiliary switchgear, simple in construction, the on off operating mode of energy feddback relay device in time.
This utility model be the technical scheme is that the HVDC relay of a kind of band auxiliary switchgear to solve its technical problem, including relay1 case and the moving contact being located in this relay1 case, static contact, and drive this moving contact to move up and down with the drive link connected with described static contact and disconnect, being positioned at bottom described relay1 case below described drive link and be provided with a press button, described drive link can press this press button when moving up and down simultaneously and make this press button be in be opened or closed.
As further improvement of the utility model, it is fixed with plastic frame in described relay housing, the middle part of described drive link is set in the base plate of this plastic frame, the upper periphery of this drive link is arranged with touch spring, the lower, outer perimeter of this drive link is arranged with back-moving spring and dynamic iron core, and this dynamic iron core is externally provided with coil.
As further improvement of the utility model, the two ends of the described back-moving spring elastic base plate of described plastic frame and the dynamic iron core of pushing against respectively, and have described dynamic iron core can be made to have towards the restoring force bottom described relay1 case.
As further improvement of the utility model, stating relay1 case is that vacuum ceramic material is made.
The beneficial effects of the utility model are: the HVDC relay construction of this band auxiliary switchgear is simple, by the on off operating mode of press button feddback relay device；Press button is the least on relay impact itself, is not take up again unnecessary space, ensureing relay work simultaneously；Press button will not be affected by the big current arc extinguishing of relay, and mechanical life is long.

Detailed description of the invention
Below in conjunction with accompanying drawing, a preferred embodiment of the present utility model is elaborated.But protection domain of the present utility model is not limited to following embodiment, the simple equivalence i.e. in every case made with this utility model claim and description changes and modifies, within the most still belonging to this utility model patent covering scope.
Refering to Fig. 1-2, a kind of HVDC relay of band auxiliary switchgear, including relay1 case 1 and the moving contact 2 being located in this relay1 case, static contact 3, and drive this moving contact to move up and down with the drive link 4 connected with described static contact and disconnect, being positioned at bottom described relay1 case below described drive link and be provided with a press button 5, described drive link can press this press button when moving up and down simultaneously and make this press button be in be opened or closed.
It is fixed with plastic frame 6 in described relay housing, the middle part of described drive link is set in the base plate of this plastic frame, the upper periphery of this drive link is arranged with touch spring 7, and the lower, outer perimeter of this drive link is arranged with back-moving spring 8 and dynamic iron core 9, and this dynamic iron core is externally provided with coil 10.
The two ends of the described back-moving spring elastic base plate of described plastic frame and the dynamic iron core of pushing against respectively, and have described dynamic iron core can be made to have towards the restoring force bottom described relay1 case.
Described relay1 case is that vacuum ceramic material is made.
The HVDC relay of this band auxiliary switchgear is by bottom relay1 case, settings button switch below drive link, during coil electricity, dynamic iron core drives drive link to move upward, dynamic, stationary contact turns on, drive link departs from press button simultaneously, switches closes, during coil blackout, dynamic iron core moves downward under the effect of back-moving spring and presses the button switch, press button disconnects, now the sound contact of relay also disconnects, thus, by the setting of this press button, drive link drives sound contact to make press button synchronize to be turned on or off while being turned on or off, press button is opened or closed signal by what holding wire output can know relay immediately.
Thus, the HVDC relay construction of this band auxiliary switchgear is simple, can be by the on off operating mode of press button feddback relay device；Press button is the least on relay impact itself, is not take up again unnecessary space, ensureing relay work simultaneously；Press button will not be affected by the big current arc extinguishing of relay, and mechanical life is long.
