Description
Technical field
The present invention relates to station field operations, and in particular to anti-misoperation locking ground stud.
Background technique
The safe and reliable every aspect concerning national economy of Operation of Electric Systems, the wherein safe and reliable operation of substation
It is the most important thing again.Electric system, the safe operation of substation are the safety for requiring to ensure equipment and the person in operation.When
When substation equipment maintenance and repair, in order to protect operator safe, it is required to the technology using temporary ground wire, temporary ground wire is articulated to
On the buried ground stud in one end, for inducing current into underground when leaking electricity, guarantee safety of workers.This temporary ground wire
It is the important tool that substation equipment maintenance and repair and Operation and Maintenance department are used to protect the person and equipment safety.Ground line is omitted scene or is used
It is improper, it may cause switching on earth wire or personal injury accident serious accident.
Unprotect accident caused by the pernicious misoperation fault of prevention switching on earth wire, prevention ground contact are bad is ground line
The main anti-error content used.For example scene, when operating temporary ground wire, existing microcomputer dispatches anti-error monitoring terminal simulation
After the step of after subpoena, operator takes the ground line of license away, shows according to computer key opens ground stud lockset, if operation
Ground line is left and is not installed at the scene by personnel, because the step of ground line has taken away, opened ground stud lockset, has also passed through, electricity
After brain key back delivery operations task, system will be mistakenly considered to be grounded own installing.The first work of substation switching operation ticket and power transformation
It needs to indicate the number being grounded at installing ground line on ticket, it is practical to grasp if certain operation need to install 2 groups or more of ground line
When making, operator by other organize it is other ground line be mistakenly attached to this step operate need to install system on the ground stud of ground line
It can not identify, default the operation of this step and be correctly completed.
Five in electric system prevent referring to: 1. preventing from accidentally dividing, close breaker；2. preventing on-load point, closing disconnecting switch；③
Prevent band cable address (conjunction) ground line (earthing switch)；4. preventing line with ground (earthing switch) from closing breaker (disconnecting switch)；⑤
Prevent mistakenly entering charged chamber.One of the important measures for being implemented as electricity safety production of electric "five-proof" function.With power grid
Continuous development, the continuous renewal of technology, error-proof device continuously improved and perfect.The design principle of error-proof device is: all
It is possible that causing the high voltage electric equipment of maloperation, error-proof device and corresponding anti-error electric blocking circuit should all be installed.
Conventional anti-misoperation locking mode mainly has: mechanical latching, procedure lock, electric interlock and electromagnetic lock.These closedown modes
Positive effect has been played in anti-delay work, the use and Operation trial by many years, the advantage and disadvantage of various tradition closedown modes
Sufficiently show.
1, mechanical latching is between switchgear or the operating position of outdoor switch blade with the mechanical machine for conditioning each other and linking
Structure reaches the locking requirement successively acted.Mechanical latching is in operation without using the auxiliary operations such as key, Ke Yishi
Now with the correct progress of operation order, automatically unlock step by step.When maloperation occurs, automatic blocking may be implemented, prevent to miss
The progress of operation.The locking requirement of forward and reverse may be implemented in mechanical latching, has locking intuitive, is hardly damaged, check man
The advantages that work amount is small, easy to operate.
However mechanical latching can only be applied between the mechanical action region of interest of inside switch cabinet and outdoor switch blade etc., with
Connection between electric elements movement cannot achieve with mechanical latching.To between two cabinets or outside switchgear and cabinet between controller switching equipment and
Locking between outdoor switch blade and switch (other plug-in strips) requires also beyond one's ability to help.So on switchgear and outdoor switch blade, only
It can also need to be aided with other blocking methods based on mechanical latching, all five anti-requirements can be reached.
2, procedure lock (or Mechanically programm's lock) is to be transmitted or replaced with operation sequence with key and reach the behaviour that successively unlocks
The requirement of work.Its great advantage is that key transmitting is not limited by distance, so application range is wider.Procedure lock is in operating process
In have key transmitting and the variation of key quantity auxiliary movement, meet and limit the operation order of unlocking condition in operation order and want
It asks, it is completely the same with track route specified in operation order, so being also easy to be received by operator.Procedure lock is in use

To blocking function, cannot be used at all under the complicated mode of connection；Although 2. the procedure lock energy with more flexible closedown mode
Meet complicated wiring, but must be provided with bus in lock-out scheme and fall to arrange lock, so that operating process is sufficiently complex；3. in great Rong
In the substation of amount, disconnecting switch divide-shut brake controls motor forward/backward rotation using button, and procedure lock can not carry out journey to button
Sequence control；4. procedure lock is also required to numerous program keys, due to installing the problems such as lack of standardization, production technology and material are poor, make
Procedure lock is easily oxidized corrosion, bite occurs, and causes to lose blocking function in certain time；5. in grid switching operation, being divided to, closing two
The precision of position not can guarantee；6. procedure lock, in use, must from the beginning, centre cannot be interrupted.So procedure lock is now
It does not use.
3, electric blocking is acted by the electromagnetic mechanism of electromagnetic coil, to realize unlock operation, is preventing mistakenly entering into charged
It is indispensable blocking element in the locking link at interval.The advantages of electric blocking be it is easy to operate, without auxiliary movement, but
It is that there is also following outstanding problems in installing and using: when 1. in general electromagnetic lock is used alone, only unlocking function
There is no reversed blocking function.It needs to be used cooperatively with electric interlocking circuit and could have forward and reverse blocking function；2. as locking
The electromagnetic lock structure of element is complicated, and moisture-sensitive is mould bad outdoors for electromagnetic coil, and insulation performance reduces, and increases the event of direct current system
Barrier rate；3. needing cabling, increase additional construction volume；4. needing to seal in the auxiliary contact of operating mechanism.According to operating experience,
Auxiliary contact are easy to produce the reliability of poor contact and influence movement；5. generally all lacking in the control switch of breaker
