Abstract
The utility model relates to a universal breaker power-on automatic switching on device which can recover power in time after an unattended power distribution room is power off. A middle relay ZJ and a time relay SJ are arranged in the control loop of a universal breaker and, the two ends of the middle relay ZJ and the time relay SJ are connected with a bridge rectifying filter circuit in parallel for supplying power for the time relay. The improvement is carried out on the original electric loop of the breaker. When the power is off, after an under-voltage coil trips and the power is on again, the power can be recovered automatically in time, which brings great convenience for a user. The utility model can recover the power automatically after under-voltage tripping, a switching on loop is not started in overcurrent protection operation and the power can be recovered after the unattended power distribution room is power off.
Description
Technical field:
The utility model relates to a kind of omnipotent breaker incoming call automatic closing device that can in time restore electricity after unattended power distribution room has a power failure can realized.
Background technology:
At present, DW15 series omnipotent breaker commonly used in the power distribution room power supply unit, during power failure, after the tripping operation of decompression coil motion, timely automatic recovery of power supply again behind the incoming call brings very big inconvenience to the user again.Need on the former electric loop of circuit breaker, improve for this reason, can automatic recovery of power supply to reach after decompression tripping operation, and do not start closing circuit during the overcurrent protection action, realize in time restoring electricity after unattended power distribution room has a power failure.
Summary of the invention:
The purpose of this utility model be to overcome the deficiencies in the prior art and provide a kind of can automatic recovery of power supply after decompression tripping operation; and the overcurrent protection action time does not start closing circuit, realizes the omnipotent breaker incoming call automatic closing device that can in time restore electricity after unattended power distribution room has a power failure.
The purpose of this utility model is achieved in that and is provided with intermediate relay ZJ and time relay sj in the control loop of omnipotent breaker, and is parallel with the bridge shape current rectifying and wave filtering circuit of powering to the time relay in this intermediate relay ZJ and time relay sj two ends.
The normal opened contact of a pair of intermediate relay ZJ in the parallel connection on the circuit breaker energy storage button in the control loop of omnipotent breaker, this intermediate relay ZJ is by a moving disconnecting point control that time-delay disconnects of time relay sj, delay time is adjusted and is 2s, low pressure occurring when preventing short circuit returns the time relay, the power supply of time relay sj is taken from switch upside source end, and the coil by bridge shape current rectifying and wave filtering circuit service time relay SJ, the normal opened contact of a pair of auxiliary relay K2 by the control of energy storage terminal point in parallel connection on the switch knob.
The utility model is the improvement of carrying out on the former electric loop of circuit breaker, and after the tripping operation of decompression coil motion, the timely automatic recovery of power supply of energy behind the incoming call brings great convenience to the user again when having a power failure.Therefore can automatic recovery of power supply after the decompression tripping operation, and do not start closing circuit during the overcurrent protection action, realize the advantage that can in time restore electricity after unattended power distribution room has a power failure.
Description of drawings:
Fig. 1 is electric control theory figure of the present utility model.
Embodiment:
Shown in 1, a kind of omnipotent breaker incoming call automatic closing device is to be provided with intermediate relay ZJ and time relay sj in the control loop of omnipotent breaker, and is parallel with the bridge shape current rectifying and wave filtering circuit of powering to the time relay in this intermediate relay ZJ and time relay sj two ends.
The normal opened contact of a pair of intermediate relay ZJ in the parallel connection on the circuit breaker energy storage button in the control loop of omnipotent breaker, this intermediate relay ZJ is by a moving disconnecting point control that time-delay disconnects of time relay sj, delay time is adjusted and is 2s, low pressure occurring when preventing short circuit returns the time relay, the power supply of time relay sj is taken from switch upside source end, and the coil by bridge shape current rectifying and wave filtering circuit service time relay SJ, the normal opened contact of a pair of auxiliary relay K2 by the control of energy storage terminal point in parallel connection on the switch knob.
K1, K2 are auxiliary relay, and DT is a closing coil, and ZJ is an auxiliary relay, and SJ is the time relay, and XK is a motor energy storage sensitive switch contact, and DF is the circuit breaker auxiliary contact, and M is an energy storage motor.
When switch was the normal condition power supply, supply voltage was a normal value, and power supply one is in the face of the M charging behind bridge shape rectifying and wave-filtering, and one side makes SJ be in operate condition, and time-delay break SJ disconnects.When switch during because of the overcurrent protection would trip, low pressure appears in the moment in short circuit, at this moment M discharges to time relay coil in the bridge shape current rectifying and wave filtering circuit, and time relay time-delay is returned, and we make delay time greater than switch trip time (DW15 Series Circuit Breakers break-time is 0.04s) by the size of selecting electric capacity, like this behind switch trip, the upper end power supply still keeps, and the time relay still is in the operate condition, and the SJ contact disconnects, ZJ is failure to actuate, also just can not automatic recovery of power supply; When tripping because of the power failure decompression, M discharges to the time relay, because of discharge time shorter, the time relay returns, behind the incoming call, the moving disconnecting point that the SJ time-delay disconnects still is in on-state, just disconnects later up to setting time, before SJ disconnects, the ZJ action, start tank circuit, connect closing circuit by the K2 normal opened contact again, realize automatic recovery of power supply.
In order to distinguish because of the protection tripping operation or because of the tripping operation of power failure decompression.Can judge that if switch trips because of overcurrent protection, then the power end of tripping operation back switch is still charged by circuit breaker power supply end is whether charged.
