Description
Technical field
Utility model relates to a kind of GIS isolating switch mechanism anti-device by mistake.
Background technology
GIS full name gas insulated combined electric appliance equipment (GasInsulatedSwitchgear), be made up of circuit breaker, isolating switch, earthed switch, instrument transformer, lightning arrester, bus, connector and outlet terminal etc., these equipment or parts are all enclosed in the shell of metallic ground, be filled with the SF6 insulating gas of certain pressure therein, therefore also claim SF6 fully closed combined electric unit.
The driving gear of isolating switch of GIS comprises: on the body housing of GIS, is extended with the spindle nose of isolating switch rotation axis, spindle nose is fixed with one end of driven connecting lever; On the output six square shaft axle head of isolating switch mechanism case, be fixed with one end of initiatively connecting lever; The other end of driving and driven connecting lever connects through kinematic link.
Along with the development of global power system self and the raising day by day to system operation reliability requirement, SF
6combined electric appliance equipment (GIS) is popularized gradually in current electric power system, and it has, and volume is little, floor space is few, dielectric strength is high, safeguard the advantages such as simple.To in GIS device interruption maintenance process, substation equipment maintenance and repair personnel need to carry out testing mechanical characteristic, loop resistance test etc. to GIS isolating switch, need the breaking-closing operating carrying out repeatedly to GIS isolating switch.Because electric power system can have a lot of GIS arranged together simultaneously, like this, once not note, often easily cause misoperation, operate the GIS isolating switch of the non-off interval in side.
In addition, in GIS device turnover job, need the overhaul of isolating switch mechanism Xiang Fan factory, then its kinematic link loses with isolating switch connecting lever and is connected, and does not have fixation, and frequent extremely easily the causing that come and go of Field Force is touched by mistake;
Further, the vibration in work, the touching in checking process, all may cause the misoperation of isolating switch connecting lever, causes GIS isolating switch to close by mistake and divide by mistake, buried potential safety hazard to service work.
Prior art adopts solution operating power secondary line to avoid disconnecting link to touch the risk of action by mistake, but this method needs more work, and need the cooperation of relay protection automation personnel, be unfavorable for carrying out of service work, situation about departing from for mechanism case and connecting rod is also inapplicable.
Utility model content
Utility model technical problem to be solved, is just to provide a kind of GIS isolating switch mechanism anti-device by mistake, and the anti-device of this mistake can realize preventing electric misoperation and preventing the charged disconnecting link function in malfunction side in maintenance debug process; For the disconnecting link of maintenance interval, prevent maintenance process from closing other disconnecting links by mistake, mechanical anti-misoperation can be increased outside electric faulty action preventing measure and move measure, make the faulty action preventing of equipment more reliable and improve the reliability of operation of power networks.
Solve the problems of the technologies described above, the technical scheme that utility model is taked is as follows:
A kind of GIS isolating switch mechanism anti-device by mistake, described GIS isolating switch mechanism comprises: on the body housing 1 of GIS, be extended with the spindle nose of isolating switch rotation axis, spindle nose is fixed with one end of driven connecting lever 2; Body housing 1 is also provided with the position-limit mechanism of described driven connecting lever 2; On the output six square shaft axle head of isolating switch mechanism case 3, be fixed with one end of initiatively connecting lever 4; The other end of driving and driven connecting lever connects through kinematic link 5; It is characterized in that: on the output six square shaft end of described isolating switch mechanism case and the spindle nose end of described isolating switch rotation axis, be respectively equipped with first, second mechanism lock;
The first described mechanism lock composition structure is: a fixed lever, its stiff end is clamped or fixed on described GIS body housing 1, the other end is connected with swingable bar one end connector, the side of the other end of swingable bar has screwed hole, and the clamping plate that the other end and of swingable bar has through hole is connected with connector;
The second described mechanism lock composition structure is: a rectangle anchor ear, internal via shape is a unfilled corner square hole, and described unfilled corner square hole may correspond to clips residence and states isolating switch rotation axis spindle nose and driven connecting lever 2 position-limit mechanism.
Described driven connecting lever 2 position-limit mechanism is the plate that one end is fixed on body, and the other end of plate is provided with non-magnetic shim bolt and points to driven connecting lever 2 swinging track place, so regulates non-magnetic shim bolt spinning in and out length and adjustable driven connecting lever 2 to swing extreme position.
Like this, add " dual fail-safe " undoubtedly to disconnecting link, after misoperation sends actuating signal, be short of power to drive switch operation, motor power will tripping automatically, ensure that the uniqueness of disconnecting link state, greatly reduces the risk of misoperation misoperation.
Compared with prior art, utility model has the following advantages:
1, after misoperation sends actuating signal, due to mechanical interlocking, it is short of power to drive switch operation, and motor power will tripping automatically, ensure that the uniqueness of disconnecting link state;
2, in GIS device turnover job, need by the overhaul of isolating switch mechanism Xiang Fan factory, then, when its kinematic link and isolating switch connecting lever lose and be connected, also can prevent isolating switch misoperation.
