Description
Technical field
The present invention relates to electric power system substation equipment maintenance and repair and maintenance technology field, particularly relate to a kind of transformer station patch anti-error locking system and detection method, computer key.
Background technology
Transformer station's electric misoperation may cause large-area power-cuts, device damage, loss of life or personal injury, even cause electrical network to shake or the serious consequence such as to disintegrate, therefore in order to effectively prevent the person and the substantial equipment accident of running misoperation of electrical equipment initiation, in conjunction with China and foreign countries' electrical operation practice, the key technical problem preventing electric fault-operation accident to be classified as the solution of electrical production urgent need was issued in 1980 by former Ministry of Water Resources and Electric Power, and the requirement of electric equipment " five prevent " is proposed in nineteen ninety, and define electrically anti-error management with regulation form (energy security [1990] No. 1110 literary compositions), run, design and use principle.Wherein, " five prevent " is specially: 1. prevent on-load from drawing by mistake or closing isolating switch by mistake; 2. prevent from drawing or falsely close circuit breaker by mistake; 3. prevent band ground wire or earthing switch blade from closing a floodgate; 4. prevent live connection of ground wire or close earthing switch blade; 5. mistakenly entering charged chamber is prevented.
Earth connection is the lifeline ensureing work of transformer substation personnel personal safety, the operation of mounting or dismounting earth connection is dangerous larger operation in electric operation, once have an accident, impact is large, consequence is serious, also be the main contributor causing artificial equipment breakdown and human casualty accident, the correctness therefore guaranteeing to install and remove earth connection is an important process of electric substation's safe and reliable operation simultaneously.
The measure that the current whole nation generally adopts is: arrange ground connection stiff end near transforming plant primary equipment or on equipment, and micro_computer five_proof padlock is installed on ground connection stiff end or electric coding lock tool is set on primary equipment, simultaneously in microcomputer transformer station's integrated operating system five anti-device main wiring diagrams (as shown in Figure 1) on set up ground stud mark, by to ground stud and relevant switch, disconnecting link, ground cutter position message composition latching logic, thus realize preventing switching on earth wire power transmission or preventing live connection of ground wire, but earth connection can not comprehensively be brought in transformer station's integrated operating system by the method for above-mentioned employing ground stud, its reason is as follows:
1, earth terminal is the ground stud using band micro_computer five_proof device, when transforming plant primary equipment overhauls, adopt the method for ground stud that installing earth connection point is restricted, but because earth connection has two kinds of characteristics that are provisional and fixing installing as required, the installing place of earth connection cannot be determined, thus cause the mode occurring two kinds of management earth connections in transformer station.Wherein, the first way to manage is for can include transformer station's integrated operating system in, and it must install ground wire at ground stud; The second way to manage is for can not include transformer station's integrated operating system in, and it need not install ground wire at ground stud, and the shortcoming of which is: buried the hidden danger of misoperation, and lacked monitoring means, easily causes the phenomenon occurring neglected loading dismounting ground wire.
2, work of transformer substation personnel can install ground stud according to working experience usually; even if identify with reference to the ground stud of main wiring diagram; also the phenomenon of neglected loading or mistake attaching pile may be there is; and there is measure error due to the distance between ground stud and repair apparatus; and the length of earth connection is fixed; therefore make staff when installing earth connection often in order to yield to ground stud, and ignore the mounting distance adopting correct mounting position and keep safe enough.
3, because earth connection, earth brace and electroscope are not all included in transformer station's integrated operating system, just the ground stud limiting installing place is included in transformer station's integrated operating system, therefore really do not play locking restriction live ground wiring phenomenon and occur.When earth connection mounts and is not connected with ground stud temporarily, transformer station's integrated operating system cannot manage it, the microcomputer controlling transformer station's integrated operating system when earth connection is removed may simulate combined floodgate power transmission, thus causes the accident such as switching on earth wire or personal injury to occur.
