Currently, in the power system, with the extensive application of ring main unit, to expose this safe problem of ring main unit,
Due to ring main unit this body structure construction, the accident that earthing switch is closed in electrification happens occasionally.When ring main unit as power supply into
Line is controlled, this there is mistake by electricity operator in use, earthing switch does not have reliable, perfect error-proof device
The hidden danger of operation and danger.In order to improve the safety of ring main unit operation, prevents ring main unit and maloperation occurs, ensure power distribution network
Operational safety, be badly in need of one kind can reliable, effective grounding switch locking device, become current industry and be badly in need of the target solved.
It is interlocked according to the electrification situation of high pressure using operating mechanism, when height is pressed with electricity, operating mechanism is latched, and works as height
When pressure is without electricity, operating mechanism unlock.Currently, such blocking device is generally powered and could be worked normally using accessory power supply mode,
Also there is the scheme that electricity is taken using voltage transformer.
Due to ring main unit this body structure construction, when as electric power incoming line, when main switch does not close a floodgate, earthing switch
Also can free switching on and off, this just brings security risk.If enter line side has been charged, grounding misoperation switch closes at this time
Lock can then cause major accident.Fig. 1 is ring main unit typical wiring figure, and 1110,1120 be on-load switch, and 1114,1124 be ground connection
Switch.All it is the electric power incoming line interval of ring network power supply between inlet wire 1110,1120 switch gap of loop wire, it is possible to 1110,
End charges when 1120 switch gate-dividing state.The existing mechanical anti-misoperation operation of ring main unit at present is as follows：1110 on-load switches close
When lock state, 1114 earthing switches cannot close a floodgate, and guarantee will not charge conjunction earthing switch.When 1114 on-load switch "on" position,
1110 earthing switches cannot close a floodgate, and guarantee will not combination switch with ground.Both the above state all meets " high pressure five-prevention operation rule
Journey ".But if when 1110 grounding switch tripping, 1114 on-load switches can close a floodgate, when this is for inlet wire interval, if enter line side
End charges and 1114 earthing switches are just there is a situation where electrification conjunction earthing switch, this is serious misoperation fault, is exhausted
To not allowing generation.
