Description
Technical field
The utility model relates to a kind of 750kV highly reliable grounding line apparatus.
Background technology
During the maintenance of power department 750kV line outage at present; If dead line is one of common-tower double-return road; Then the ultra category-B earthed switch in line side place needs reliable ground in the transformer station; Ultra category-B earthed switch be behind the arc extinguishing circuit interrupter grounding again through the ground connection disconnecting link that possesses certain connecting-disconnecting function of ground connection disconnecting link reliable ground, its reliability is extremely important, ultra category-B earthed switch is again required equipment during line outage.Through test, when the 750kV common-tower double-return construction of line had a power failure for one time, the dead line induced electricity was up to 35000 volts; When the line side earthed switch overhauls in standing; Need the artificial installing earth connection in the line side, this just has higher requirement to the line side reliable ground, in case imperfect earth or earth point wiring come off; Gently then cause the heavy maintainer's injures and deaths that then cause of discharge arcing, there is very big danger in personal safety.
Summary of the invention
The purpose of the utility model is to propose a kind of on 750kV common-tower double-return road or parallel laying circuit wherein during a loop interruption maintenance; Or at general interruption maintenance during, can not produce the arcing of discharging, safe and reliable 750kV highly reliable grounding line apparatus with the line outage maintenance.
The purpose of the utility model is achieved in that 750kV highly reliable grounding line apparatus is made up of former earthing device, circular baffle plate, pole and insulating bar.The connecting rod of former earthing device spins with the insulation fixed block.Be inserted with pole in the insulating bar, insulating bar is stretched out at the pole two ends, the fixing circular baffle plate in pole upper end, and the lower end is fixed with draw ring or turning handle.
Owing to implement technique scheme, just make that the 750kV highly reliable grounding line of the utility model is safe and reliable, can not produce the discharge arcing.In mounting or dismounting handling safety, simple and easy during earth connection, it can guarantee when 750kV line outage is overhauled, and the reliable ground of equipment has increased guarantee to the safety of the person.
