Abstract
The invention relates to the field of electrical switches, in particular to a three-station disconnecting switch with a grounding indication switch and a grounding contact of the three-station disconnecting switch. The three-station disconnecting switch with the grounding indication switch comprises a moving contact and the grounding contact corresponding to the moving contact, wherein the grounding indication switch which is used for being triggered by the moving contact and indicating the grounding state of the disconnecting switch when the moving contact and the grounding contact are switched on in place is arranged on the grounding contact. In the using process, unless the moving contact and the grounding contact have already been switched on in place, the grounding indication switch does not give out signals, conversely, once the grounding indication switch gives out signals, the moving contact and the grounding contact must have already been switched on in place. Therefore, the three-station disconnecting switch with the grounding indication switch solves the problem that an existing three-station disconnecting switch can not accurately indicate the grounding state.
Description
Technical field
The present invention relates to electric switch field, particularly relate to a kind of tri-station isolating switch and grounding contact thereof with ground connection indication.
Background technology
Tri-station isolating switch is a kind of electric equipment very common in electric power system.In use, once staff has carried out improper operation because judging the ground state of tri-station isolating switch by accident, can directly cause accident, cause great loss.Therefore the ground state of accurately grasping tri-station isolating switch is most important.
At present, the ground state of tri-station isolating switch is normally indicated by the operating mechanism of tri-station isolating switch, yet, existence due to factors such as the screw rod transmission gap of operating mechanism, the fractures of nylon screw mandrel, operating mechanism often can not reflect the ground state of tri-station isolating switch really, when tri-station isolating switch is when separating brake is not in place, what operating mechanism externally may show is switch sub-gate signal, when tri-station isolating switch is when combined floodgate is not in place, what operating mechanism externally may show is switch switching signal.Especially when operating mechanism breaks down while not working, according to signal, carry out breaker operator and will bring unforeseen consequence.
Known by above analysis, there is the problem of ground state misregister in current tri-station isolating switch.
Summary of the invention
The object of the present invention is to provide a kind of tri-station isolating switch with ground connection indication, to solve existing tri-station isolating switch, can not accurately indicate the problem of ground state.
Meanwhile, the present invention also aims to provide the grounding contact of above-mentioned tri-station isolating switch.
In order to address the above problem, tri-station isolating switch with ground connection indication of the present invention is by the following technical solutions: with the tri-station isolating switch of ground connection indication, comprise moving contact and the grounding contact corresponding with moving contact, described grounding contact is provided with the ground connection indicator cock that passive contact while putting in place for closing a floodgate at moving contact and grounding contact triggered and indicated the ground state of described isolating switch.
Described ground connection indicator cock has shift bar, and moving contact triggers ground connection indicator cock by described shift bar when putting in place with grounding contact combined floodgate.
Described ground connection indicator cock is sensitive switch.
The grounding contact of tri-station isolating switch is by the following technical solutions: the grounding contact of tri-station isolating switch, this grounding contact is provided with the ground connection indicator cock that triggers and indicate the ground state of isolating switch for passive contact when it puts in place with corresponding switch on of moving contact.
Described ground connection indicator cock has shift bar, and moving contact triggers ground connection indicator cock by described shift bar when putting in place with grounding contact combined floodgate.
Described ground connection indicator cock is sensitive switch.
Because this grounding contact with the tri-station isolating switch of ground connection indication is provided with the ground connection indicator cock that triggers and indicate the ground state of described isolating switch for passive contact when moving contact puts in place with grounding contact combined floodgate, therefore, when in use, unless moving contact and grounding contact close a floodgate and put in place, otherwise ground connection indicator cock is can not send signal, on the contrary, as long as ground connection indicator cock sends signal, moving contact and grounding contact are inevitable closes a floodgate and puts in place, as can be seen here, should solve the problem that existing tri-station isolating switch can not accurately be indicated ground state with the tri-station isolating switch of ground connection indication.
Further, shift bar has facilitated the setting to the installation site of ground connection indicator cock, can make the setting position of ground connection indicator cock become more flexible; After adopting sensitive switch as ground connection indicator cock, because it is enough sensitive, therefore can reduce to greatest extent the impact on the moving contact of tri-station isolating switch and grounding contact.
Accompanying drawing explanation
Fig. 1 is the structural representation with the embodiment of the tri-station isolating switch of ground connection indication;
Fig. 2 is the structural representation of embodiment of the grounding contact of tri-station isolating switch.
Embodiment
The embodiment of the tri-station isolating switch of indicating with ground connection, as shown in Figure 1, this tri-station isolating switch comprises moving contact 11 and the grounding contact 12 corresponding with moving contact 11, and when moving contact 11 puts in place with grounding contact 12 combined floodgates, tri-station isolating switch is in ground state.
In other embodiment of the tri-station isolating switch with ground connection indication, ground connection indicator cock can also be for optoelectronic switch etc., and shift bar can also consist of the button of being located on ground connection indicator cock.
The embodiment of the grounding contact of tri-station isolating switch, as shown in Figure 2, the structure of the grounding contact in the embodiment of the structure of this grounding contact and the above-mentioned tri-station isolating switch with ground connection indication is identical, and it will not go into details herein.
