Abstract
The utility model discloses a breaker tripping signal lamp circuit which comprises a TXIJ coil, a 1TBIJ coil, a 2 TBIJ coil and an operation mechanism, wherein the TXIJ coil, the 1TBIJ coil, the 2 TBIJ coil and the operation mechanism are serially connected in sequence. By improvement, namely, as two ends of the 1TBIJ coil are connected with a shunt resistor R in parallel, the breaker tripping signal lamp circuit can solve the problem of false tripping due to low actuation power of a relay conveniently in the premise of not changing the functions of an operation box, thus being simpler and more practical compared with relay replacement.
Description
Technical field
The utility model relates to a kind of circuit breaker trip tally circuit.
Background technology
In common breaker operator loop, general design is to start trip signal lamp (red light) when jumping circuit breaker by the protection action, and circuit breaker is to start combined floodgate indicator light (green light) in "on" position, distinguishes the emergency stop valve trip and the normal running of circuit breaker with this.But can run into breaker operator loop as shown in Figure 1 in actual debug process, the 1TBIJ relay string that startup breaker protection tripping operation indicator light is used is in the combined floodgate monitoring circuit.Normal condition is that breaker closing HD (green) lamp is bright, but because the 1TBIJ starting power is too small, 1TBIJ starts under this state, started TD (red) lamp simultaneously, caused the entanglement of circuit breaker running status indication, this causes misunderstanding just may for the operation maintenance personnel, and influence is to the judgement of circuit breaker running status.
The utility model content
The technical problems to be solved in the utility model is, a kind of circuit breaker trip tally circuit is provided, to overcome improper startup that prior art exists, to cause the deficiencies such as entanglement of circuit breaker running status indication easily.
The technical solution of the utility model is: it comprises TXIJ coil, 1TBIJ coil, 2TBIJ coil and operating mechanism before improving, TXIJ coil, 1TBIJ coil, 2TBIJ coil and operating mechanism are connected in series successively, after the improvement, be at 1TBIJ coil two ends parallel resistance R.
By improving, under the prerequisite that does not influence the every function in whole operation loop, adopt a shunt resistance in parallel at 1TBIJ coil two ends, solve its error starting problem well.This parallel connection shunt resistance is required: the first, at the breaker closing state, under the situation of combined floodgate monitoring circuit conducting, assurance 1TBIJ relay reliably is failure to actuate; The second, start under the situation of jumping circuit breaker in protection, guarantee that the 1TBIJ action message goes to light trip signal lamp TD by TXJ.
The beneficial effects of the utility model: the utility model can be under the prerequisite that does not change each function of control box, solves the little and malfunction problem that causes of actuating of relay power easily, and relay is simple and practical compared with changing, and has passed through the test of actual motion.
Description of drawings
Fig. 1 is the schematic diagram before improving;
Fig. 2 is a schematic diagram of the present utility model.
Embodiment
Embodiment of the present utility model: it comprises the TXIJ coil before improving; the 1TBIJ coil; 2TBIJ coil and operating mechanism; the TXIJ coil; the 1TBIJ coil; 2TBIJ coil and operating mechanism are connected in series successively; before improvement; as shown in Figure 1; starting breaker protection tripping operation indicator light (TD) starts by trip signal relay (TXJ); and trip signal relay (TXJ) is by the contact startup of anti-trip relay (1TBIJ) relay; normal condition is that breaker closing HD (green) lamp is bright; but because the 1TBIJ starting power is too small; 1TBIJ starts under this state; start TD (red) lamp simultaneously, caused the entanglement of circuit breaker running status indication.Circuit after the improvement under the prerequisite that does not influence the every function in whole operation loop, adopts the shunt resistance R in parallel at 1TBIJ coil two ends as shown in Figure 2, solving anti-trip relay (1TBIJ) error starting, and causes the overdue bright phenomenon of signal lamp.
In Fa Er power plant booster stations breaker operator loop, ran into same problem, resistance R by one 5 ohm in parallel at 1TBIJ coil two ends, with regard to having solved trip signal lamp overdue bright problem under the breaker closing state, working properly in actual motion like this.
