Abstract
The utility model provides an anti-misoperation lock-out system, which achieves the function that a plurality of ground switch operation sites are locked out by force by utilizing a conventional high-voltage live display device in a distribution network ring main unit and additionally arranging an electroscope, a lock-out lock, an intelligent hand-held terminal, a communication base and a PC (Personal Computer) management system. Before an operating staff closes a grounding switch or hanging a grounding wire, electricity detection has to be conducted on the electroscope through the intelligent hand-held terminal, so that misoperation accidents caused by closing the grounding switch during electrification are completely prevented. The anti-misoperation lock-out system consists of the PC management system, the communication base, the intelligent hand-held terminal, the high-voltage live-wire display device, the electroscope and the lock-out lock, wherein the electroscope is connected with the high-voltage live display device and used for detecting the electrified state of an incoming cable of the ring main unit; the lock-out lock is mounted at an operating mechanism of either the grounding switch or a grounding wire and used or locking out the grounding switch or the grounding wire; and two unique identity recognition codes are built in both the electroscope and the lock-out lock, and the coding information can be distinguished by the intelligent hand-held terminal.
Description
Technical field
The utility model relates to a kind of anti-error locking system, relates in particular to the implementation method of the anti-error locking system of the switching station ring main unit in a kind of brand-new power industry distribution network systems.By when operating the ring main unit earthed switch, introduce and force the electrical verification operation, thereby prevent the charged splice grafting of operating personnel ground switch or hanging earthing conductor.
Background technology
High speed development along with urban construction, the distribution Rapid Expansion, transform and constantly carry out, new special line specially becomes the user and does not stop to insert, the variation renewal speed of network is very fast, the range of application of ring main unit is more and more wider, the importance of ring main unit in urban distribution network becomes increasingly conspicuous, the safe operation that how to ensure ring main unit seems extremely important, but the distribution operating personnel are when operating ring main unit at present, basically rely on ring main unit self with " five anti-device ", and fact proved ring main unit self with " five anti-device " can not prevent the generation of misoperation fully, particularly prevent the generation of " charged splice grafting ground switch ", thereby cause serious consequence, undermine equipment or injure the person.
Ring main unit " five is anti-" means and prevents to divide by mistake, run jointly the pass, prevent the on-load branch, close isolating switch or stab contact, (or band earth connection) send electricity when preventing that earthed switch from closing, and prevents charged splice grafting ground switch (or hanging earthing conductor), prevents five-term measures such as mistakenly entering into charged isolation ward." 3～35kV ac metal closing switch gear " (GB3906-91) stipulate, except prevent mistake divide, run jointly the pass can adopt indicative, all the other " four is anti-" all must adopt the locking of anti-error property.Existing ring main unit as according to the normal enterprising mode of connection that goes out down, can satisfy " five is anti-" requirement.To preventing charged splice grafting ground switch (or hanging earthing conductor), interlock by on-load switch and earthed switch and realize, have only when the on-load switch disconnection, when the outlet side does not have electricity, but ability operational grounding switch.But present switching station generally all adopts cable turnover line, and for incoming line cabinet (at interval), wiring goes out on advancing under being, therefore after on-load switch disconnects, ring main unit (at interval) downside is still charged, and this moment, the pernicious misoperation fault of charged splice grafting ground switch will take place for the operational grounding switch.In order to ensure the power distribution network safe and stable operation, prevent the pernicious misoperation fault of charged mistake splice grafting ground switch, traditional mode is to adopt the standard machinery padlock to live operating equipment, release is preceding carries out artificial judgment to potential indicator.The mode that the method for standard machinery padlock locking can only be managed artificially goes to control the misoperation of charged splice grafting ground switch, can't realize forced blocking, also just can't stop misoperation fully.
Summary of the invention
Can not prevent the deficiency of the misoperation of charged splice grafting ground switch fully at existing ring main unit, the purpose of this utility model is to provide a kind of anti-error locking system, utilize existing high voltage display device in the distribution ring main unit, by increasing the mode of electroscope, locking lockset, intelligent handheld terminal, communication seat and PC management system, realize forced blocking function to a plurality of earthed switch operating points.Operating personnel must carry out electrical verification by intelligent handheld terminal on electroscope before splice grafting ground switch or hanging earthing conductor, have only identify true no-voltage after, can next step unlocking operation, stopped the misoperation fault of charged splice grafting ground switch fully.
The utility model is achieved through the following technical solutions:
A kind of anti-error locking system, this system is made up of PC management system, communication seat, intelligent handheld terminal, high voltage display device, electroscope and locking lockset; Described electroscope is connected with high voltage display device, is used to detect the electriferous state of looped network cabinet wire cable; Described locking lockset is installed on the operating mechanism place of earthed switch or earth connection, is used for locking earthed switch or earth connection; The all built-in unique identification coding of described electroscope and locking lockset, this coded message can be discerned by intelligent handheld terminal.
