Description
Technical field
The utility model belongs to electrical equipment technical field; The control protective relaying device is thrown a kind of the having of moving back and is thrown the electric power pressing plate that moves back condition checkout gear in the secondary device; State is moved back in the throwing of pressing plate; Except passing through the position judgment of front handle, can also pass through the intelligence judgement automatically of electric component on the pressing plate.
Background technology
Transformer station's grid switching operation is divided into primary equipment and secondary device, and the throwing, retreating of protection pressing plate are main projects of secondary device operation.The protection pressing plate is also named protection in flakes; In traditional various protections, pressing plate is used for being switched on or switched off certain loop, is the bridge and the tie of protective device contact external wiring; Can the function that be related to protection normally play a role with the action outlet, therefore extremely important.
Protective relaying device in the secondary equipment in power system is the basic facilities that guarantee the safe operation of electric power primary equipment, through the operation relay-protection pressing plate, can control the throwing, retreating of protective device or the operational mode of change protective device.And the misoperation of pressing plate then possibly make the electric power primary equipment lose protection, jeopardizes the safe operation of electrical network.Along with the expansion of scale of power and the development of resist technology, the quantity of relay-protection pressing plate is multiplied, thereby its management work is had higher requirement.
The anti-misoperation of secondary device does not still have ACU in the electric power system, though in management, all formulated a series of control measures, can not really fundamentally solve the anti-error problem of secondary device.Secondary device moves back, leaks throwings, leakage and the power system accident that reason causes such as move back and happen occasionally owing to the miscarrying of pressing plate, mistake.At present; Manual type is still adopted in inspection to the pressing plate position; Operations staff or maintainer throw when moving back the contrast pressure board and adhere to and record carrying out pressing plate; Rule is moved back in the throwing of pressing plate can only be with operations staff's experience, this way to manage consumption consuming time worker, and keep away unavoidable artificial miscarrying, mistake and move back, leak throwings, leakage and phenomenon such as move back.Existing all kinds of presser device all can not be realized combining of pressing plate state-detection and anti-error system, because there are not anti-error means, the misoperation of pressing plate very easily occurs, and the safe operation of crisis electrical network brings tremendous loss to electric power system.
Simultaneously, in existing microcomputer anti-error device, only the electric power primary equipment is carried out anti-error control, not to the anti-misoperation step of secondary device pressing plate.So very easily under the situation of secondary device pressing plate misoperation, carry out the operation of primary equipment, make the anti-misoperation process start a leak, cause misoperation pressing plate and primary equipment simultaneously, bring great hidden to electric power netting safe running.
Secondary pressing plate in the electric power system at present, common pressing plate has only which kind of state it is in through outward appearance handle position judgment, and its inside does not have condition checkout gear.Like this, time etc. is moved back in the state of pressing plate, its throwing just needs artificial record, and the one, accuracy is low, and the 2nd, workload is big, and efficient is low.
Summary of the invention
The purpose of the utility model is to provide throw the electric power pressing plate that moves back condition checkout gear a kind of having; Can be real-time offer controller to the pressing plate state: comprise that pressing plate is in the throwing state and still moves back state, when operates, manages information such as whether throwing into the position; Reduced artificial operate miss and judged hidden danger such as bad, its information accuracy improves greatly; Improved operating efficiency on the other hand.
The utility model is realized through following technical scheme:
Throw the electric power pressing plate that moves back condition checkout gear a kind of having, and includes the pressing plate main body, wherein, also includes position detection component; Said position detection component is provided with pressing plate throwing, retreating state detection unit, and said pressing plate throwing, retreating state detection unit includes the tongue tube detection components; Said pressing plate main body includes: pressing plate handle piece, pressing plate pedestal and be fixed on two groups of conductive components on the pressing plate pedestal, and the pressing plate handle piece is fixed on the pressing plate pedestal; Position detection component is near the inner end setting of pressing plate handle piece; Said pressing plate handle piece has two service positions: when the pressing plate handle piece is in throwing state service position, and the conducting element conducting in two groups of conductive components and the pressing plate handle piece, pressing plate throwing, retreating state detection unit obtains also output and throws status signal; When the pressing plate handle piece is in when moving back the state service position, the conducting element in two groups of conductive components and the pressing plate handle piece breaks off, and pressing plate throwing, retreating state detection unit obtains also output and moves back status signal.
The beneficial effect of the utility model is following:
Throw the electric power pressing plate that moves back condition checkout gear a kind of the having of the utility model, owing to include position detection component; Said position detection component is provided with pressing plate throwing, retreating state detection unit, and said pressing plate throwing, retreating state detection unit includes the tongue tube detection components; Said pressing plate main body includes: pressing plate handle piece, pressing plate pedestal and be fixed on two groups of conductive components on the pressing plate pedestal, and the pressing plate handle piece is fixed on the pressing plate pedestal; Position detection component is near the inner end setting of pressing plate handle piece; Said pressing plate handle piece has two service positions: when the pressing plate handle piece is in throwing state service position, and the conducting element conducting in two groups of conductive components and the pressing plate handle piece, pressing plate throwing, retreating state detection unit obtains also output and throws status signal; When the pressing plate handle piece is in when moving back the state service position, the conducting element in two groups of conductive components and the pressing plate handle piece breaks off, and pressing plate throwing, retreating state detection unit obtains also output and moves back status signal.Miscarrying, the mistake that can prevent relaying protection secondary pressing plate move back, leak throwings, leak and misoperation such as to move back, provide operation primary equipment and secondary pressing plate anti-error one overlap solution.The present invention is applicable to transformer station, collection control center.Realization is from the primary equipment to the secondary device, from manual station, nobody stand framework of comprehensive anti-error system solution of digital transformer substation.Utilize pressing plate to throw and move back detection, collection, the communication technology, operation of secondary pressure plate is dissolved in the primary equipment anti-misoperation.Use computer key operation order indication operation secondary pressing plate.Secondary pressing plate miscarrying, mistake move back, leak throwings, throwing can not the operating operation ticket when moving back in below the operation of step, play indicative indirect locking secondary pressing plate.Thereby avoid human negligence to cause miscarrying, the mistake of secondary pressing plate to move back, leak the generation that throwings, leakage such as move back at misoperation; Guarantee relay protection of power system secondary pressing plate throw move back correct; And can effectively alleviate operating personnel's workload and operating pressure, increase work efficiency.
