Description
Technical field
The present invention relates to power technology field, relate in particular to one and utilize ABB disconnecting link switching key to realize generatorThe method of anti-misoperation locking is a kind of power plant mechanical type anti-misoperation locking device.
Background technology
Generator is in the time of operation, and in PT at the exits of generators cabinet, electric braking switch cubicle, electric pressure is generally13.8kV, 15.75kV, 18kV. Some power generator outlet PT cabinet, electric braking cabinet door lock keyFor common key, can open easily cabinet door, personnel's casualty accident of very easily getting an electric shock. Anti-according to power systemArrange requirement, need to install mechanical type anti-misoperation locking device additional at PT at the exits of generators cabinet, electric braking switch cubicle.
Prior art is, on generator outlet disconnecting link, power lock is installed. When generator outlet disconnecting linkAt open position, ensure that PT at the exits of generators cabinet, electric braking switch cubicle have a power failure, and use power lock by disconnecting linkBe locked in open position, then displace the anti-misoperation locking of opening PT at the exits of generators cabinet, electric braking cabinet doorKey, opens cabinet door.
Summary of the invention
For above-mentioned problems of the prior art, the invention provides one and utilize ABB disconnecting link to switch key in factThe method of existing generator anti-misoperation locking, object is to solve the difficult problem that ABB disconnecting link is difficult for installing power lock, due toABB switch operation mechanism has key to switch blocking function, utilizes this function can on disconnecting link, not install power additionalLock, conveniently realizes PT at the exits of generators cabinet, electric braking switch cubicle installs mechanical type anti-misoperation locking device additional.
The present invention is achieved through the following technical solutions:
Utilize ABB disconnecting link switching key to realize the method for generator anti-misoperation locking, be:
Install anti-misoperation locking device additional at PT at the exits of generators cabinet, electric braking switch cubicle;
Anti-misoperation locking key and the ABB disconnecting link of opening PT at the exits of generators cabinet, electric braking cabinet door are dividedGate position locking key links together with key ring, and key ring is welded; Make anti-misoperation locking key withABB disconnecting link open position locking key can not be separated;
The method concrete operation step of generator anti-misoperation locking is as follows:
1. insert electric operating key in generator outlet switch operation mechanism;
2. pull open generator outlet disconnecting link, PT at the exits of generators cabinet, electric braking switch cubicle are had a power failure;
3. take out open position locking key in generator outlet switch operation mechanism, take out anti-misoperation locking key simultaneouslySpoon, is latched in open position by generator outlet disconnecting link;
4. use the key operated PT at the exits of generators cabinet of anti-misoperation locking, electric braking cabinet door.
Advantage and beneficial effect are as follows:
The present invention guaranteeing under safe prerequisite, and the creationary ABB disconnecting link that solved is difficult for installing power lockA difficult problem, has simple, safe and reliable, the great reduction of erection time of method, the advantage such as reduce expenses. EspeciallyBe applicable to having ABB disconnecting link to carry out the power plant of mechanical anti-misoperation locking device installation. The method has been passed through the practice inspection in power stationTest, confirm that the method is safe and reliable, reference is large, has very strong promotional value.
Below in conjunction with specific embodiment, the present invention will be further described in detail.
Detailed description of the invention
The present invention is a kind of method that the ABB of utilization disconnecting link switching key is realized generator anti-misoperation locking.
One, to switch locking principle as follows for ABB switch operation of the present invention mechanism key:
There are three locking keys in ABB switch operation mechanism, is respectively electric operating key, open position locking keySpoon and closing position locking key. Due to three mutual lockings of key, can only take out a wherein key at every turn,To realize different blocking functions. Refer to table 1.
Two, implementation method.
1. install anti-misoperation locking device additional at PT at the exits of generators cabinet, electric braking switch cubicle;
2. anti-misoperation locking key and the ABB disconnecting link of PT at the exits of generators cabinet, electric braking cabinet door will be openedOpen position locking key links together with key ring, and key ring is welded. Make anti-misoperation locking key withABB disconnecting link open position locking key can not be separated.
Three, use step
1. insert electric operating key in generator outlet switch operation mechanism;
2. pull open generator outlet disconnecting link, PT at the exits of generators cabinet, electric braking switch cubicle are had a power failure;
3. take out open position locking key in generator outlet switch operation mechanism and (take out anti-misoperation locking key simultaneouslySpoon), generator outlet disconnecting link is latched in to open position;
4. use the key operated PT at the exits of generators cabinet of anti-misoperation locking, electric braking cabinet door.
The blocking function table that table 1, ABB switch operation mechanism three realize locking key.
Claims (1)
1. utilize ABB disconnecting link switching key to realize the method for generator anti-misoperation locking, it is characterized in that:
Install anti-misoperation locking device additional at PT at the exits of generators cabinet, electric braking switch cubicle;
Anti-misoperation locking key and the generator outlet ABB disconnecting link open position locking key of opening PT at the exits of generators cabinet, electric braking cabinet door are linked together with key ring, and key ring is welded; Anti-misoperation locking key and generator outlet ABB disconnecting link open position locking key can not be separated;
The method concrete operation step of generator anti-misoperation locking is as follows:
