Description
Technical field
The present invention relates to a kind of GIS isolating switch mechanisms miss anti-device.
Background technology
GIS full name gas insulated combined electric appliance equipments (Gas Insulated Switchgear), by chopper, keep apart
Pass, earthed switch, transformer, spark gap, bus, connector and outlet terminal etc. are constituted, and these equipment or part are all closed
In the shell of metallic ground, SF6 insulating gas filled with certain pressure inside which, therefore also referred to as SF6 fully closed combined electric units.
The driving gear of isolating switch of GIS includes：On the body housing of GIS, the axle of disconnecting switch rotary shaft is extended with
Head, is fixed with one end of driven connecting lever on spindle nose；On the six square shaft shaft end of output of isolating switch mechanism case, it is fixed with and actively turns
One end of arm；The other end Jing kinematic links connection of driving and driven connecting lever.
The increasingly raising required with the development of global power system itself and to system operation reliability, SF6Combination
Electric equipment (GIS) is gradually popularized in current power system, and it has, and small volume, floor space are few, dielectric strength is high, dimension
The advantages of protecting simple.During to GIS device interruption maintenance, substation equipment maintenance and repair personnel need to carry out machinery to GIS disconnecting switch
Characteristic test, loop resistance test etc., need to carry out multiple breaking-closing operating to GIS disconnecting switch.Due to power system meeting
There are many GIS arranged together simultaneously, so, once not noting, tend to cause maloperation, operate side and do not have a power failure
The GIS disconnecting switch at interval.
In addition, in GIS device turnover job, need the overhaul of isolating switch mechanism Xiang Fan factories, then its kinematic link with
Disconnecting switch connecting lever loses connection, and no fixation, round frequently extremely the easily causing of Field Force are touched by mistake；
Further, the vibration in work, the touching in checking process, may all cause disconnecting switch connecting lever misoperation, cause
GIS disconnecting switch is closed by mistake and is divided by mistake, has buried potential safety hazard to service work.
Prior art avoids disconnecting link from touching the risk of action by mistake using solution operation power secondary line, but this method need compared with
Many work, and the cooperation of relay protection automation personnel is needed, it is unfavorable for the development of service work, for mechanism case and connecting rod disengaging
Situation is not simultaneously applied to.
The content of the invention
The technical problem to be solved, is just to provide a kind of GIS isolating switch mechanisms and misses anti-device, the anti-dress of the mistake
Put and can realize preventing electric misoperation and prevent from overhauling the powered disconnecting link function in malfunction side in debugging process；For maintenance
The disconnecting link at interval, prevents maintenance process from closing other disconnecting links by mistake, can increase the dynamic measure of mechanical anti-misoperation outside electric faulty action preventing measure,
Make the faulty action preventing of equipment more reliable and improve the reliability of operation of power networks.
Above-mentioned technical problem is solved, the technical scheme that the present invention takes is as follows：
A kind of GIS isolating switch mechanisms miss anti-device, and described GIS isolating switch mechanisms include：In the body housing of GIS
On 1, the spindle nose of disconnecting switch rotary shaft is extended with, on spindle nose, is fixed with one end of driven connecting lever 2；It is additionally provided with body housing 1
The position-limit mechanism of the driven connecting lever 2；On the six square shaft shaft end of output of isolating switch mechanism case 3, active connecting lever 4 is fixed with
One end；The other end Jing kinematic links 5 of driving and driven connecting lever connect；It is characterized in that：In the output six of the isolating switch mechanism case
On the spindle nose end of square shaft end and the disconnecting switch rotary shaft, first, second mechanism lock is respectively equipped with；
Described the first mechanism lock constitutes structure and is：One fix bar, it is external that its fixing end is clamped or fixed in the GIS sheets
On shell 1, the other end be connected with connector with a swingable bar one end, be provided with screwed hole on the side of the other end of swingable bar,
The other end of swingable bar is connected with connector with a clamping plate for being provided with through hole；
Described the second mechanism lock constitutes structure and is：One rectangle anchor ear, internal via shape be a unfilled corner square hole, the unfilled corner side
Hole can correspond to clips residence and state disconnecting switch rotary shaft spindle nose with 2 position-limit mechanism of driven connecting lever.
Described 2 position-limit mechanism of driven connecting lever is fixed on the plate on body for one end, and the other end of plate is provided with non-magnetic shim bolt
Point at 2 swinging track of driven connecting lever, it is that the driven connecting lever 2 of scalable swings the limit so to adjust non-magnetic shim bolt spinning in and out length
Position.
So, undoubtedly " dual fail-safe " is added to disconnecting link, after maloperation sends action signal, be short of power to drive knife
Lock is operated, and motor power will tripping automatically, it is ensured that the uniqueness of disconnecting link state, greatly reduces the wind of maloperation misoperation
Danger.
Compared with prior art, the present invention has advantages below：
1st, after maloperation sends action signal, due to mechanical interlocking, which is short of power to drive switch operation, motor electricity
Source will tripping automatically, it is ensured that the uniqueness of disconnecting link state；
2nd, in GIS device turnover job, need the overhaul of isolating switch mechanism Xiang Fan factories, then its kinematic link with keep apart
When pass connecting lever loses connection, disconnecting switch misoperation can be also prevented.
