Technical field:
The utility model belongs to distribution operation and the equipment of overhaul management safety prevention and control with the change equipment state, especially a kind of two station isolating switches that have ground connection.
Background technology:
At present, the 10KV isolating switch that uses in the power distribution network is GW9-10 or GW10-10 type, this class isolating switch does not have earthing device, a kind of equipment that uses as obvious breaking point only, when the 10KV of transformer station, switching station cable outlet, and distribution transformer high-side lead, 10KV circuit T contact be when using isolating switch to draw down cable, and all directly the pile crown of the isolating switch on the via line, on-load switch, fuse is received on the circuit.When repair apparatus, earth connection can't hang, and the staff does not have the earth connection protection, and personal safety is difficult to guarantee.
Summary of the invention:
For overcoming the unsafe factor that existing 10KV isolating switch exists, the utility model provides a kind of two station isolating switches of 10KV band ground connection.For achieving the above object, the technical scheme taked of the utility model is:
A kind of two station isolating switches of 10KV band ground connection, by the main electrical scheme fixed contact, active wiring moving contact, ground connection moving contact, ground connection fixed contact, insulation column, base constitutes, and it is characterized in that insulation column is fixed on the base, and the ground connection fixed contact is fixed on one side of base, the ground connection moving contact is fixed on the unidirectional main electrical scheme moving contact with the ground connection fixed contact, and the main electrical scheme fixed contact is fixed on the insulation column.
Described ground connection moving contact is to make with cross section such as oval-shaped sheffield plate.
Described ground connection fixed contact and main electrical scheme road fixed contact are to adopt sheffield plate to curve the right angle, can contact with circuit effectively under the situation that lead and lead-in wire do not stress.
Described main electrical scheme road moving contact is to make with two blocks of arc silver-plated coppers.
Described insulation column adopts silicon rubber to make, and base and locking device adopt stainless steel material to make.
On isolating switch, install earthing device additional, after disconnecting the circuit breaker electrical verification that cooperates with it, can directly isolating switch be drawn back, make ground connection moving contact rotation incision ground connection fixed contact simultaneously, thereby with the circuit or the equipment ground of maintenance, to prevent staff's Danger Electric shock risk effectively.It is characterized in that: with cross section such as disciform sheffield plate as the ground connection moving contact, with two arc sheffield plates as the circuit moving contact, the isolating switch force part of avoiding causing because of operation is out of shape; Ground connection fixed contact and circuit fixed contact adopt sheffield plate to curve the right angle, can contact with circuit effectively under the situation that lead and lead-in wire do not stress; Insulation column adopts silicon rubber, has increased creepage distance, can prevent the line fault that pollution flashover brings effectively; Base and locking device adopt stainless steel material, avoid the corrosion that is in operation.Earth terminal can separate with the isolating switch body, can freely assemble during use.
Useful technique effect of the present utility model is: adopt quality material, with simple, practical, be convenient to install, be convenient to be operating as principle, locking device is arranged, can not cause the isolating switch edge of a knife to come off naturally and the charged misoperation phenomenon on splice grafting ground by mistake.Not only solve the problem that how to prevent that staff's person from getting an electric shock, also simplified operating personnel's operation sequence, reduced the operating time, improved power supply reliability indirectly.
