Description
Technical field
The utility model belongs to power switch cabinet apparatus field, refers more particularly to the earth connection of 10 kilovolts of enclosed switchgear bus bar side.
Background technology
All transformer station's 10 kilovolts of outlet switchs are closed vacuum switch at present, Bei Tan change, Linze change, the change of respectful south is only had to provide grounding trolley, and other transformer station does not all have supporting corresponding grounding trolley, also because the grounding trolley model of each switch cubicle manufacturer production, size are not quite similar, also just can not be general mutually.If when not having the transformer station of grounding trolley to carry out bus interruption maintenance, must break rules and regulations first to open above certain switch cubicle, the shut of side, also to remove busbar joint box and could install ground connection, so not only violating the regulations, but also unsafe troublesome operation method and existing security concepts run counter to.
Utility model content
The utility model is intended to the defect overcoming prior art, provides the earth connection of 10 kilovolts of enclosed switchgear bus bar side, and before 10 kilovolts of bus interruption maintenances, can carry out installing earth connection security measure work safely, quickly and easily.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme:
A kind of earth connection of 10 kilovolts of enclosed switchgear bus bar side, comprise movable contact conducting bar, connector, movable contact conducting bar is provided with line nose plane vertically, wiring nose plane opens wired nose bolt hole M8mm along axis centre place, the movable contact conducting bar end opens being provided with line nose plane has interior screw thread, the movable contact conducting bar other end is connected with the telescopic moving contact of closed vacuum switch cart, connector large-diameter end is provided with the male thread matched with interior screw thread, connector small-diameter end portions is provided with smooth department, movable contact conducting bar is threaded with connector male thread, connect into as a whole in the metallic sheath that connector smooth department is closely inserted in 10kV earth wire insulating rod upper end, use powerful self-plugging rivet to rivet tightly fixing.
Further, interior screw thread width is less than male thread width.
Further, connector is that brass is made.
Compared with prior art, the utility model has following beneficial effect:
The utility model provides a kind of reliable, convenient and practical security tool, and structure is simple, and fail safe is high; Use the present invention to carry out installing earth connection, not only solve and originally oneself must not open unsafe factor of switch cubicle side, closed guard below, and the technology and safety requirements that meet 10 kilovolts of common three-phase shortcircuit earth connections can be reached.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the earth connection of the utility model 10 kilovolts of enclosed switchgear bus bar side;
Fig. 2 is the structural representation of movable contact conducting bar described in the utility model;
Fig. 3 is the partial enlarged drawing of movable contact conducting bar described in the utility model;
Fig. 4 is the structural representation of connector described in the utility model.
Embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the utility model, and be not used in restriction the utility model.
As Figure 1-4, the earth connection of 10 kilovolts of enclosed switchgear bus bar side, comprises movable contact conducting bar 1, connector 2, movable contact conducting bar 1 is provided with line nose plane 11 vertically, line nose plane length 40 ± 1mm, width 20 ± 1mm; After movable contact conducting bar 1 excises redundance, length is 900mm; Wiring nose plane opens wired nose bolt hole M8mm along axis centre place, the movable contact conducting bar end opens being provided with line nose plane has interior screw thread 13, interior screw thread width 14mm; The movable contact conducting bar other end is connected with the telescopic moving contact of closed vacuum switch cart.Connector 2 large-diameter end is provided with the male thread 21 matched with interior screw thread, and length is 15mm, male thread diameter 30mm, and interior screw thread width is less than male thread width.Connector 2 small-diameter end portions is provided with smooth department 22, and length is 30mm.Connector length is 45mm, and connector is that brass is made.Movable contact conducting bar 1 is threaded with connector 2 male thread; Connect into as a whole in the metallic sheath that connector smooth department is closely inserted in 10kV earth wire insulating rod upper end, use powerful self-plugging rivet to rivet tightly fixing.The common earth wire insulating rod length 1000mm of 10kV.
Note: till the earth wire insulating rod connected as one and brass connector precession movable contact conducting bar are screwed.
During use, before 10 kilovolts of enclosed switchgear bus section interruption maintenances, according to the traditional thread binding order of establishing of " safety " associated ground, first install earth terminal, then our operations staff one people has been with insulating gloves, opens switch cubicle closed guard, then Special grounding wire three-phase is inserted in fixed contact one by one under another person's monitoring, and check moving contact whether to insert on fixed contact the degree of depth and fastening reliable till, the effect of tape insulation gloves prevents charging equipment electrostatic from hurting sb.'s feelings.So far, Special grounding wire installing security measure work task completes.
The utility model provides a kind of reliable, convenient and practical security tool, and structure is simple, and fail safe is high; Use the present invention to carry out installing earth connection, not only solve and originally oneself must not open unsafe factor of switch cubicle side, closed guard below, and the technology and safety requirements that meet 10 kilovolts of common three-phase shortcircuit earth connections can be reached.
The foregoing is only and execution mode of the present utility model is described; be not limited to the utility model; for a person skilled in the art; all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
