Abstract
The utility model relates to an opening/closing control loop of a VS1 circuit breaker, in particular to a structure for monitoring the opening/closing control loop of the VS1 circuit breaker. The structure is that a resistor Rf is connected in parallel with two ends of a relay KO and a resistor RO in the opening/closing control loop of the VS1 circuit breaker, and a trip indicator light LD is connected to a closing pulse input point Z4. The structure mainly aims to solve the problem in a conventional structure that when switched on in a faulty circuit, the circuit breaker can not be switched on next time, and can effectively monitor the opening/closing control loop of the VS1 circuit breaker.
Description
Technical field
The utility model relates to VS1 circuit breaker on/off switch control loop, particularly a kind of structure that VS1 circuit breaker on/off switch control loop is monitored.
Background technology
Circuit breaker is when running status; whether its on/off switch loop is intact; it is the necessary condition of the normal operation of assurance equipment; usually adopt to be serially connected in the indicator light in the on/off switch loop or to close branch position supervisory relay and monitor; for sub-gate circuit, it is the last execution link of relaying protection, if at operation time-division closing circuit fault is arranged; when the relaying protection would trip; the branch fault is refused in generation, the expansion that causes the accident, and its consequence is hardly imaginable; for closing circuit; though problem character is not serious as the divide-shut brake loop, if the circuit breaker of gate-dividing state in service, especially stand-by power supply automatic closing loop; if its closing circuit has fault; in case in the time of need carrying out closing operation, just produce and refuse to close fault, have influence on the reliability of powered operation; therefore the supervision of closing circuit also has its necessity in certain occasion.The VS1 circuit breaker is after drawing the advanced technology of the foreign VD4 of ABB AB vacuum circuit-breaker, the high-pressure vacuum breaker of Development and Production at home, this product design is rationally reliable, in power supply-distribution system, extensively be employed at present, and producing by how tame production unit, its secondary control loop is also similar with VD4, in its closing circuit, the 4 pairs of functions of connecting equally are identical borrows point, the only different (see figure 1) of arrangement position, in Fig. 1, closing circuit monitors it is to utilize the separating brake indicator light to be connected in series normally closed contact QF, inserts its closing circuit again, under normal circumstances, operation can be satisfied the normal running requirement fully, but when following situation takes place, will have influence on normal running, we find when debugging now, if during operation, breaker closing is on out of order circuit, then just tripping operation immediately of circuit breaker, because anti-trip relay KO moved at that time, after the closing pulse signal disconnected, relay K O just drew into the loop by RO → KO/QF → QF → LD to positive supply.At relay K O two ends voltage drop about 90V is arranged approximately,, be enough to make KO to remain on attracting state greater than its return voltage, therefore will cause close a floodgate next time to produce and refusing to close phenomenon, must the control dump, allow KO return after, serve the control power supply, just can carry out normal running.
Summary of the invention
The purpose of this utility model is to provide a kind of structure that VS1 circuit breaker on/off switch control loop is monitored, it mainly solves in the existing structure, when breaker closing is on out of order circuit, can cause close a floodgate next time and produce the problem of refusing to close phenomenon, it can effectively monitor VS1 circuit breaker on/off switch control loop.
The utility model solves the problems of the technologies described above the technical scheme that is adopted.
A kind of structure that VS1 circuit breaker on/off switch control loop is monitored, it is characterized in that: it is relay K O, resistance R O two ends 1 resistance R _ f in parallel on VS1 circuit breaker on/off switch control loop, and the indicator light LD that will trip is connected to closing pulse input point Z4.
The beneficial effects of the utility model are: the utility model can be avoided when breaker closing is on out of order circuit, can cause close a floodgate next time and produce the problem of refusing to close phenomenon, and it can effectively monitor VS1 circuit breaker on/off switch control loop.
Description of drawings
Fig. 1 is the structural representation that existing VS1 circuit breaker on/off switch control loop monitors.
Fig. 2 is a structural representation of the present utility model.
Embodiment
See also Fig. 2, it is a kind of structure that VS1 circuit breaker on/off switch control loop is monitored of the utility model.As shown in the figure: it is relay K O, resistance R O two ends 1 resistance R _ f in parallel on VS1 circuit breaker on/off switch control loop, and the indicator light LD that will trip is connected to closing pulse input point Z4.
By said structure, the utility model just can carry out normal monitoring to closing circuit, can't produce any anomaly.The selection of R5 parameter and check as follows.
Certain VS1 of manufactory circuit breaker element test is learnt: RO=18K, KO=28K, the about 22K of LD substitutional resistance, selecting R5 is 1K Ω/25W, after closing pulse is removed.Loop all-in resistance R5=(RLD+ (RO+RKO) XR5)/(RO+RKO+R5)=(22K+ (18K+28K) X1K)/18K+28K+1K=22.98K.I=220/22.98K=9.6Ma，U2=9.6X0.98=9.38V，UKO={9.38V/(18+28)K}28K=5.7r。The return voltage of common type direct current relay〉the specified 10%=11r of U, now checking UKO two terminal voltages is 5.7V, so can reliably return, LD can reliably monitor combined floodgate.
In sum, be preferred embodiment of the present utility model only, be not to be used for limiting practical range of the present utility model, promptly all equivalences of doing according to the content of the utility model claim change and modify, and all should be technology category of the present utility model.
