Abstract
The utility model discloses an interlock is operated with ground connection to looped netowrk cabinet, be in including mounting panel, ground connection axle, ground connection handle hole, lower door plant and setting electromagnetic lock assembly on the mounting panel, it adsorbs iron plate to be equipped with on the door plant down, it opens / closes down the door plant with the electromagnetic lock assembly cooperation to adsorb iron plate, the electromagnetic lock assembly internalization is provided with a round pin post, outer and the fixed connection separation blade of electromagnetic lock assembly is stretched out to round pin post one end, the one end setting of separation blade is between ground connection axle and ground connection handle hole, the ground connection axle is adjusted well with the ground connection handle hole. This interlock simple structure, when the earthing switch that if and only if was in the operating position, electromagnetic lock assembly was electrified to unclamp door plant down, lower door plant just can be opened, and maintainer can safeguard, keep in repair, satisfies safe and reliable's standard.
Description
Technical field
The utility model relates to ring main unit technical field, particularly relates to a kind of ring main unit ground connection operation interlocking device.
Background technology
High-voltage ring main unit is that electric power is joined, indispensable electrical equipment of powering, in high-voltage ring main unit, attendant is maintenance, repair conveniently, the lower door-plate of ring main unit need be opened, and must guarantee that before lower door-plate is opened earthed switch is in "on" position, ring main unit can not be charged, otherwise easily cause the accident.
The ground connection operation interlocking device of existing high-voltage ring main unit is in Long-Time Service process, because mechanical linkage which controls easily blocks inefficacy because part is many, the complicated easy displacement of lock core program is inaccurate, and before cannot ensureing that lower door-plate is opened all the time completely, earthed switch is in "on" position.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the utility model provides a kind of structure simple, safe and reliable ring main unit ground connection operation interlocking device.
The utility model solves the technical scheme that its technical problem adopts:
A kind of ring main unit ground connection operation interlocking device, the electromagnetic lock component comprising mounting panel, grounding shaft, ground connection handle hole, lower door-plate and be arranged on described mounting panel, described lower door-plate is provided with absorption iron plate, described absorption iron plate coordinates door-plate under opening/closing with electromagnetic lock component, a pin is movably set with in described electromagnetic lock component, it is outer and be fixedly connected with catch that electromagnetic lock component is stretched out in described pin one end, one end of described catch is arranged between grounding shaft and ground connection handle hole, and described grounding shaft and ground connection handle hole align.
As the improvement of technique scheme, described electromagnetic lock component also comprises push button, described push button is connected with pin, described push button is unblanking to switch between shelves and locking shelves, when push button is pushed into locking shelves, described pin drives catch holding between grounding shaft and ground connection handle hole and earthed switch is in gate-dividing state, when push button be pushed into unblank grade time, described pin drives catch to connect the installation site off-centring certain distance of the earth's axis and ground connection handle hole, grounding shaft and ground connection handle hole coordinates and earthed switch is in "on" position.
As the improvement of technique scheme, when earthed switch is in gate-dividing state, electromagnetic lock component is charged holds absorption iron plate, described lower door-plate is in tight lock status, when earthed switch is in "on" position, electromagnetic lock component power-off loses suction and unclamps absorption iron plate, and described lower door-plate is in can opening.
The beneficial effects of the utility model have:
This interlock structure is simple, by the cooperation between mobile pin grounding shaft capable of blocking and ground connection handle hole, earthed switch is made to be in gate-dividing state, electromagnetic lock component is charged simultaneously, electromagnetic lock component tightly holds lower door-plate, the unearthed door-plate at present of ring main unit is effectively prevented to be opened, on the contrary, if and only if when earthed switch is in "on" position, electromagnetic lock component is not charged, thus unclamps lower door-plate, and lower door-plate just can be unlocked, attendant can carry out maintenance, repair, meets safe and reliable standard.
Accompanying drawing explanation
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail, wherein:
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
See Fig. 1, a kind of ring main unit of the present utility model ground connection operation interlocking device, the electromagnetic lock component 3 comprising mounting panel 1, grounding shaft 2, ground connection handle hole, lower door-plate and be arranged on mounting panel 1, a pin 4 is movably set with in electromagnetic lock component 3, it is outer and be fixedly connected with catch 5 that electromagnetic lock component 3 is stretched out in pin 4 one end, one end of catch 5 is arranged between grounding shaft 2 and ground connection handle hole, and grounding shaft 2 and ground connection handle hole align.
In addition, lower door-plate is provided with absorption iron plate, absorption iron plate coordinates door-plate under opening/closing with electromagnetic lock component 3, electromagnetic lock component 3 holds absorption iron plate time charged, absorption iron plate is unclamped during ground connection, electromagnetic lock component 3 also comprises push button 6, and push button 6 is connected 4 with pin, and push button 6 is unblanking to switch between shelves and locking shelves.
When push button 6 is pushed into locking shelves, pin 4 drives catch 5 holding between grounding shaft 2 and ground connection handle hole, grounding shaft 2 and ground connection handle hole disconnect, earthed switch is in gate-dividing state, electromagnetic lock component 3 is charged holds absorption iron plate, thus holding lower door-plate tightly, lower door-plate is in tight lock status, cannot open.
When push button 6 be pushed into unblank grade time, pin 4 drives catch 5 to connect the installation site off-centring certain distance of the earth's axis 2 and ground connection handle hole, grounding shaft 2 and ground connection handle hole coordinate, earthed switch is in "on" position, electromagnetic lock component 3 power-off loses suction, unclamp absorption iron plate, lower door-plate is in can opening.
This interlock structure is simple, and and if only if when earthed switch is in "on" position, and lower door-plate just can be unlocked, and attendant can carry out maintenance, repair, meets safe and reliable standard.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should belong to protection range of the present utility model.
