Description
Technical field
Use the technical field of high voltage power distributing cabinet when the utility model relates to tie feeder distribution between transformer station, be specifically related to a kind of locking device of combined floodgate grounding switch when preventing high voltage power distributing cabinet with voltage.
Background technology
Model is KYN61 series 35kV, model is the distribution complete set of equipments that KYN28 series 10kV high voltage power distributing cabinet has perfect " five prevent " function.As long as but it is charged to there is circuit when using as tie feeder power distribution cabinet between transformer station, the hidden danger that grounding switch just can close a floodgate.Conventional power transmission operating sequence is: 1) disconnect our station high voltage power distributing cabinet (load side) grounding switch; 2) upper level (mains side) high voltage power distributing cabinet grounding switch is disconnected; 3) after telemetry link insulation, upper level (mains side) high voltage power distributing cabinet breaker closing; 4) our station high voltage power distributing cabinet breaker closing, complete operation.But when complete power transmission operation front 3 step time, as our station high voltage power distributing cabinet occur as circuit breaker trolley can not push in cabinet, locking device exception etc. situation need overhaul time, now operating personnel as neglect, the consequence of charged co-grounding switch can be caused.Otherwise power failure operation consequence duplicates.
Utility model content
Technical problem to be solved in the utility model to have for the high voltage power distributing cabinet between transformer station, tie feeder arranged in prior art that tie feeder is charged by mistake to be closed grounding switch Problems existing and provide a kind of and operate reliable, effective, that small investment, maintenance cost the are low locking device preventing high voltage power distributing cabinet combined floodgate grounding switch with voltage in operation.
Following technical scheme is adopted for solving technical problem of the present utility model:
A kind of locking device preventing high voltage power distributing cabinet combined floodgate grounding switch with voltage, comprise electromagnetic lock, described electromagnetic lock is located on the grounding switch of high voltage power distributing cabinet, described electromagnetic lock comprises electromagnetic lock core and electromagnetic lock coil, described electromagnetic lock core is located at the grounding switch operating handle jack position of high voltage power distributing cabinet, described electromagnetic lock coil is connected with electrification in high voltage transducer, and described electrification in high voltage transducer is connected with the grounding switch inlet wire of high voltage power distributing cabinet.
Described electrification in high voltage transducer is CG9-35Q electrification in high voltage transducer.
Described high voltage power distributing cabinet is KYN61 series 35kV or KYN28 series 10kV.
The utility model provides and a kind ofly operates reliable, effective, that small investment, maintenance cost the are low locking device preventing high voltage power distributing cabinet combined floodgate grounding switch with voltage.The high voltage power distributing cabinet between transformer station, tie feeder arranged in operation, the grounding switch of high voltage power distributing cabinet installs electromagnetic lock, the lock core of electromagnetic lock is arranged on high voltage power distributing cabinet grounding switch operating handle jack position, the inlet wire of the high voltage power distributing cabinet that higher level transformer station and transformer station of subordinate tie feeder are arranged arranges electrification in high voltage transducer, when electrification in high voltage transducer detects charged on inlet wire, weak electric signal after electrification in high voltage transducer is charged disconnects electromagnetic lock wire loop through transforming, electromagnetic lock core ejects, stop that high voltage power distributing cabinet grounding switch operating handle inserts in jack, realize the charged function cannot closing high voltage power distributing cabinet grounding switch.The utility model has that design operation is simple, reliable, maintenance load is little, the advantage of small investment, for electrical operation personnel operation provides reliable and secure guarantee, have anti-error reliable for effect, use and maintenance is convenient, invest little feature.
Accompanying drawing explanation

Fig. 2 is that the utility model transformer station interconnection uses connection layout;
Fig. 3 is the utility model electromagnetic lock schematic diagram of movements.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail:
As shown in Figure 1 and Figure 2, a kind of locking device preventing high voltage power distributing cabinet combined floodgate grounding switch with voltage, comprise electromagnetic lock, electromagnetic lock is arranged on the grounding switch that high voltage power distributing cabinet is KYN61 series 35kV or KYN28 series 10kV, electromagnetic lock comprises electromagnetic lock core 2 and electromagnetic lock coil 1, electromagnetic lock core 2 is arranged on the grounding switch operating handle jack position 3 of high voltage power distributing cabinet, electromagnetic lock coil 1 is connected with CG9-35Q electrification in high voltage transducer, and electrification in high voltage transducer is connected with the grounding switch inlet wire of high voltage power distributing cabinet.
The high voltage power distributing cabinet of KYN61 series 35kV or KYN28 series 10kV to be arranged between transformer station on interconnection, interconnection high voltage power distributing cabinet grounding switch operating handle jack position installs electromagnetic lock core 2, when after high pressure dead electricity, when transducer can not detect line voltage distribution, electromagnetic lock converts through internal circuit, and loop is connected, electromagnetic lock action message, regained by lock core, operating handle can enter by grounding switch smoothly, does not affect normal ground switch operation; When electrification in high voltage transducer detects that circuit is charged, electromagnetic lock dead electricity, lock core ejects, and stops that high voltage power distributing cabinet grounding switch operating handle inserts in jack, realizes the charged function cannot closing high voltage power distributing cabinet grounding switch.
Electromagnetic lock operating principle is: high-voltage switch cabinet wire inlet cable end place is charged, because high-voltage switch cabinet wire inlet cable is connected with electrification in high voltage transducer, as shown in Figure 3, A, B, C are charged, after loop judges, K1, K2 contact disconnects, and 220V electric power loop cannot be connected, electromagnetic lock dead electricity, electromagnetic lock core 2 ejects, block the grounding switch operating handle jack position 3 of high voltage power distributing cabinet, ground cutter operating handle cannot operate, and realizes the charged function cannot closing high voltage power distributing cabinet grounding switch.
