Description
Technical field
The present invention relates to station field operation, be specifically related to anti-misoperation locking ground stud.
Background technology
The safe and reliable every aspect concerning national economy of Operation of Electric Systems, wherein the safe and reliable operation of transformer station is again the most important thing.Power system, the safe operation of transformer station are that requirement is in operation the safety of guarantee equipment and the person.When substation equipment maintenance and repair, in order to protect operator safety, it is required to use the technology of temporary ground wire, temporary ground wire is articulated on the buried ground stud in one end, for inducing current into underground during when electric leakage, it is ensured that safety of workers.This temporary ground wire is that substation equipment maintenance and repair and Operation and Maintenance department are for protecting the person and the important tool of equipment safety.Earth lead omits on-the-spot or improper use, is likely to result in switching on earth wire or personal injury accident serious accident.
The bad unprotect accident caused of the prevention pernicious misoperation fault of switching on earth wire, prevention ground contact is the main anti-error content that earth lead uses.Such as on-the-spot when operating temporary ground wire, after anti-error monitoring terminal simulation subpoena dispatched by existing microcomputer, operator take the earth lead of license away, after the step shown according to computer key opens ground stud lockset, if earth lead is retained in scene and does not install by operator, because earth lead is taken away, the step opening ground stud lockset is passed through the most, after computer key back delivery operations task, system will be mistakenly considered earth lead, and oneself installs.Need to indicate the numbering of earth lead at installing earth lead on substation switching operation ticket and the first work ticket of power transformation, if certain operation need to install 2 groups and above earth lead, during practical operation, the earth lead of other groups is attached to the operation of this step by operator mistakenly need to install system None-identified on the ground stud of earth lead, gives tacit consent to the operation of this step and the most indeed completes.
In power system five are anti-to be referred to: 1. prevent from dividing by mistake, closing chopper；2. prevent on-load from dividing, closing disconnecting switch；3. band cable address (conjunction) earth lead (earthed switch) is prevented；4. prevent line with ground (earthed switch) from closing chopper (disconnecting switch)；5. mistakenly entering charged chamber is prevented.One of important measures being implemented as electric power safety production of electric "five-proof" function.Along with the development of electrical network, the continuous renewal of technology, error-proof device is updated and perfect.The design principle of error-proof device is: all high voltage electric equipments likely causing maloperation, all should install error-proof device and corresponding anti-error electric blocking loop.
Conventional anti-misoperation locking mode mainly has: mechanical latching, procedure lock, electric interlock and electromagnetic lock.These closedown modes have played positive role in anti-delaying work, and through use for many years and Operation trial, the pluses and minuses of various tradition closedown modes the most fully show.
1, mechanical latching is the locking requirement reaching successively action between switch cubicle or the operating position of outdoor switch blade with the mechanical mechanism conditioning each other and linking.Mechanical latching is in operation without using the auxiliary operations such as key, it is possible to achieve correctly carrying out with operation order, unlocks the most step by step.When maloperation occurs, it is possible to achieve automatic blocking, stop the carrying out of maloperation.Mechanical latching can realize forward and reverse locking requirement, has locking directly perceived, is hardly damaged, the advantages such as maintenance workload is little, easy to operate.
But mechanical latching can only be applied between the mechanical action region of interest of inside switch cabinet and outdoor switch blade etc., and contacting between electric elements action cannot realize with mechanical latching.Locking between two cabinets or between switch cubicle and the outer controller switching equipment of cabinet and between outdoor switch blade and switch (other plug-in strips) is required beyond one's ability to help.So on switch cubicle and outdoor switch blade, also can only need to be aided with other blocking methods based on mechanical latching, whole five anti-requirements can be reached.
2, procedure lock (or claiming Mechanically programm's lock) is to reach the requirement of successively unlocking operation with key with operation sequence transmission or displacement.Its great advantage is that key transmission is not limited by distance, so range of application is wider.Procedure lock has transmission and the auxiliary movement of key number change of key in operation, meets the requirement of the operation order limiting condition of unblanking in operation order, completely the same, so the most easily being accepted by operator with the track route of regulation in operation order.The problem that procedure lock is in use exposed is: 1. some procedure lock function is simple, can only use under the better simply mode of connection, owing to not possessing horizontal blocking function, can not use under the complicated mode of connection at all；Although the procedure lock 2. with more flexible closedown mode can meet the wiring of complexity, but must be provided with bus in lock-out scheme and arrange lock so that operating process is sufficiently complex；3., in jumbo transformer station, disconnecting switch divide-shut brake uses button control motor forward/backward rotation, and procedure lock cannot be carried out programme-control to button；4. procedure lock is also required to numerous program keys, owing to installing the problem such as lack of standardization, production technology and material difference, makes the easy oxidized corrosion of procedure lock, bite occurs, lose blocking function in causing certain time；5. the precision in grid switching operation, dividing, closing two positions cannot ensure；6. when procedure lock uses, it is necessary to starting anew, centre can not be interrupted.So procedure lock does not uses now.
3, electric blocking is the electromagnetic mechanism action by solenoid, realizes solving latching operation, is indispensable blocking element in the locking link prevent mistakenly entering charged chamber.The advantage of electric blocking is easy to operate, does not has auxiliary movement, but there is also following outstanding problem in installing and using: when the most in general electromagnetic lock is used alone, and only unlocking function does not has reverse blocking function.Need and electric interlocking circuit is with the use of just having forward and reverse blocking function；2. the electromagnetic lock structure as blocking element is complicated, and solenoid moisture-sensitive out of doors is mould bad, and insulating properties reduce, and add the fault rate of straight-flow system；3. need cabling, increase extra construction volume；4. need to seal in the auxiliary contact of operating mechanism.According to operating experience, auxiliary contact easily produce loose contact and affect the reliability of action；5. the control at chopper switchs, and the most all lacks locking measure.
Computer anti-misoperation and lockout device, from the beginning of the nineties in last century, microcomputer technology has been put into anti-misoperation locking field.Computer anti-misoperation and lockout device is a kind of employing computer technology, prevents the device of electric misoperation for high-tension switch gear.Through the development over more than 10 years, computer anti-misoperation and lockout device is the most ripe, and is widely popularized in power system.On-the-spot substantial amounts of secondary locked loop is become the five-defence block rule base in computer by software by microcomputer anti-misoperation system, achieve the digitized of anti-misoperation locking, and the anti-error function that can not realize or be difficulty with in the past can be realized, it should say it is state-of-the-art technology and the leap of electrical equipment anti-misoperation locking technology.
Error proof locking system of microcomputer is typically made up of function element such as anti-error main frame, computer key, romote controlled locking control unit, mechanical coding lock, electric coding lock and intelligent locks, fully meets the requirement of electrical equipment " five prevent " function.System sets up latching logic data base, on-the-spot substantial amounts of secondary electric blocking loop is become the anti-misoperation locking rule base in computer, anti-error main frame uses rule base that simulation preview operation is carried out latching logic judgement, record meets the simulation preview operating procedure of anti-misoperation locking rule, generates practical operation program.Anti-error main frame uses following three kinds of modes to be unlocked operation according to practical operation program, different according to device latchup mode: 1) computer key unlocks；2) directly control intelligent lock by romote controlled locking control unit etc. to unlock；3) by communication interface, monitoring system is performed unblock.
Equipment, according to anti-error main frame and the prompting of computer key, is operated by operations staff successively.To not meeting the operation of program, equipment refusal unlocks, and operation cannot be carried out, thus prevents the generation of maloperation.By following the tracks of the virtual condition of field apparatus, receiving the back information of computer key, after current operation is confirmed by anti-error main frame, carry out next step operation, until operation task terminates.
