Description
Technical field
The utility model relates to a kind of secondary circuit state monitoring apparatus, and specifically a kind of ring main unit secondary circuit positioning indicator, belongs to Relay Protection Technology in Power System field.
Background technology
Along with the development of electronic technology and the communication technology, power distribution network has progressed into the intelligent epoch turning to feature with informationization, automation, interaction, and traditional 10kV ring main unit is also replaced by intelligent ring main unit just gradually.The most significant feature is, intelligent ring main unit possesses remote control or electrically operated ability.Intelligent ring main unit is made up of first and second equipment; its primary equipment refers to circuit breaker, isolating switch and the operating mechanism thereof etc. that are directly used in delivery of electrical energy; secondary device refers to the low voltage electrical equipment of monitoring primary equipment, controlling, regulating, protect, as button, indicator light, control switch, relay, control cables, instrument, signalling arrangement etc.Remote control (electronic) operation is exactly utilize secondary device to drive primary equipment to realize ring main unit divide-shut brake.Remote control and electric operating be two kinds of convenience again safety mode of operation.
The reason of remote control (electronic) operation failure can be divided into primary equipment fault and secondary device fault two kinds.The main cause of primary equipment fault has: operating mechanism fault, drive failure, dynamic/static contact fault etc.The main cause of secondary device fault has: relay fault, control switch fault, secondary wiring broken string, divide-shut brake coil fault etc.Identify primary equipment fault or secondary device fault is very necessary, malfunction elimination scope can not only be reduced, find fault point as early as possible, and due to the difference of job function, primary equipment and secondary device often adhere to two division managements separately, differentiation primary equipment fault and secondary device fault are conducive to distinguishing responsibility, repair fault as early as possible.
At present, the only resource of differentiation ring main unit primary equipment fault, secondary device fault adopts manual operation to judge exactly.Because manual operation directly acts on primary equipment, secondary device is not needed to participate in, therefore think if remote control (electronic) operation failure manual operation success, secondary device fault can be judged as, if remote control (electronic) operation and manual operation all failures, be judged as primary equipment fault.
Such determination methods is obviously not exclusively accurately.The separation of primary equipment and secondary device is divide-shut brake coil, secondary device under normal circumstances, remote control (electronic) operation will make divide-shut brake coil charges, under the effect of electromagnetic force, the striker of divide-shut brake coil is by ejection and collide mechanism action contact, then, operating mechanism action makes ring main unit circuit breaker disconnect (closing).Suppose because the reason such as condensation, rainwater causes operating mechanism corrosion, even if when secondary device is working properly, divide-shut brake coil striker correctly ejects, operating mechanism akinesia is made because striker moment is not enough, but because artificially firmly make operating mechanism success action, so just secondary device fault may be mistaken for after changing manual operation.Under open-air conditions, the phenomenon of ring main unit operating mechanism generation corrosion is very general, and therefore distinguish primary equipment fault and secondary device fault by manually operated method, the possibility of erroneous judgement is higher.
