Earthed switch is mainly used in switchgear and line maintenance, for preventing in maintenance process incoming call suddenly, during interruption maintenance by equipment ground, protection equipment, system and personal safety.Conventionally outlet is passed through to earthed switch shorted to earth, discharge completely, can not cause like this electric shock accidents being caused by misdelivery electricity or the anti-power transmission of circuit; Therefore must be by all ground connection of the two ends of checkout equipment.The earthed switch of high voltage power distributing cabinet, be generally output load side joint ground, in the time of our examination and repair for high-pressure power distribution cabinet load side, (as: fastening bolt, dismounting cable etc.) will disjunction cut off switch, the earthed switch of power distribution cabinet closes simultaneously, can prevent that like this incoming call causes electric shock accidents suddenly, can drain in addition residual charge, be conducive to maintenance safety.But the structure of existing earthed switch is larger, can not meet at present the economy of electric power system switching devices, the requirement that reliability is more and more higher.
Utility model content
For the above-mentioned problems in the prior art, the purpose of this utility model is to provide the earthed switch for switchgear, in the situation that guaranteeing equipment, system and personal safety, reduce the volume that earthed switch takies in switchgear, to meet the economy of electric power system switching devices, the requirement that reliability is more and more higher.For realizing above-mentioned utility model object, the utility model is provided for the earthed switch of switchgear, described earthed switch comprises disconnecting link and the insulator of connection, and what also independently connect respectively isolating switch, switchgear in described switchgear by a L-type metal connecting piece goes out device line and ground path.
Preferably, described L-type metal connecting piece is connected with the insulator of earthed switch.
More preferably, described L-type metal connecting piece with the connected mode of the insulator of earthed switch for being fixedly connected with.
Preferably, described L-type metal connecting piece comprises vertical component effect and horizontal part, and described horizontal part is connected with isolating switch, described vertical component effect respectively independently selectivity connecting valve equipment go out device line and ground path.
Preferably, described horizontal part is connected with the contact of isolating switch.
Preferably, respectively connecting insulator and disconnecting link successively of a side of described vertical component effect, and the opposite side of vertical component effect with go out device line and be connected.
Preferably, described vertical component effect is by being connected described ground path with disconnecting link.
Preferably, described disconnecting link comprises fixed part and movable part.
More preferably, the variation of the position relationship between described fixed part and movable part realizes the combined floodgate of described disconnecting link or opens a sluice gate.
Preferably, when described fixed part is vertical with movable part, disconnecting link closes a floodgate.
Preferably, when described fixed part is parallel with movable part, disconnecting link is opened a sluice gate.
Preferably, concrete distribution the on-fixed of the contact in described switchgear, can select according to the actual requirements.
In sum, compared with prior art, the earthed switch that the utility model provides, especially as the earthed switch for switchgear, in the situation that guaranteeing equipment, system and personal safety, decapacitation meets outside the requirement that economy, the reliability of electric power system switching devices is more and more higher, described earthed switch also and in switchgear, reduced one group of post insulator and wire and other connector being connected between isolating switch, reduce the volume that earthed switch takies in switchgear, thereby reduced switchgear material requested and taken up room.
Accompanying drawing explanation
The structural representation of the earthed switch that Fig. 1 provides for the utility model.
Embodiment
Below in conjunction with embodiment and accompanying drawing to the utility model do further in detail, intactly explanation.
Fig. 1 is the structural representation of earthed switch 2, as shown in Figure 1, earthed switch 2 can retain under the prerequisite of original function, by a L-type metal connecting piece 201 respectively independently in connecting valve equipment isolating switch, switchgear go out device line and ground path 4; Wherein, the horizontal part 2012 of L-type metal connecting piece 201 is connected with isolating switch, vertical component effect 2011 respectively independently selectivity connecting valve equipment go out device line and ground path 4.Be specially, horizontal part 2012 is connected with the contact 1 of isolating switch, a side of vertical component effect 2011 with go out device line and be connected, and the opposite side of vertical component effect 2011 connecting insulator 3 and disconnecting link 202 respectively from top to bottom; Described vertical component effect 2011 is by being communicated with and being connected described ground path 4 with disconnecting link 202.Described disconnecting link 202 comprises fixed part 2022 and movable part 2021, change in location between described fixed part 2022 and described movable part 2021 realizes the combined floodgate of described disconnecting link 202 or opens a sluice gate, in the time that described fixed part 2022 is parallel with described movable part 2021, described disconnecting link closes a floodgate; In the time that described fixed part 2022 is vertical with described movable part 2021, described disconnecting link is opened a sluice gate.
In the time that workman needs repair apparatus or system, the moving contact at the isolating switch pole two ends of switchgear is separated with corresponding fixed contact respectively, and isolating switch is opened a sluice gate, and switchgear is out of service, now fixed part 2022 is vertical with movable part 2021, and described disconnecting link 202 closes a floodgate; Be that contact 1 is connected with disconnecting link 202 by L-type metal connecting piece 201, and further by 4 one-tenth paths of movable part 2021 and ground path, can make like this electric current pass through ground path 4 flows out, drain the residual charge in circuit, can preventing in addition that suddenly incoming call causes carries out safety inspection by electric shock accidents.
After maintenance completes, by the moving contact at the isolating switch pole two ends of switchgear respectively with corresponding fixed contact closure, isolating switch closes a floodgate, be that isolating switch is channel status (in the time of breaker closing in switchgear in switchgear, further make equipment inner looping be channel status), now fixed part 2022 is parallel with movable part 2021, and described disconnecting link 202 is opened a sluice gate; Be that contact 1 opens circuit with disconnecting link 202, contact 1 is connected with insulator 3 by L-type metal connecting piece 201, simultaneously with go out device line and be connected, earthed switch 2 and switchgear open circuit, and switchgear inner looping becomes path, switchgear normally moves.
For the space clear distance between bus in assurance equipment conforms with the regulations (being not less than 125mm in air dielectric), when in prior art, conventional earthed switch does not have L-type metal connecting piece, need to be between earthed switch and contact multi-link one group of post insulator and wire, take volume larger, be unfavorable for economy; And the earthed switch that the utility model provides is by L-type metal connecting piece spatial design cleverly, both met the space clear distance requirement between bus in switchgear, reduce again the quantity of post insulator and wire and other connector, size and volume that earthed switch takies in switchgear are reduced, thereby reduce the required production material of switchgear and space, reduced the production cost of switchgear.
Finally be necessary described herein: above embodiment is only for being described in more detail the technical solution of the utility model; can not be interpreted as the restriction to the utility model protection range, some nonessential improvement that those skilled in the art makes according to foregoing of the present utility model and adjustment all belong to protection range of the present utility model.
