The filter compensation device comprehensive protection and reactance operation control circuit is a first group of operation control circuit and a second group of operation control circuit, a plurality of groups of operation control circuits can operate simultaneously in the actual operation process, the connection method of other groups is the same as that of the first group of operation control circuit and the second group of operation control circuit, the operation control circuits of all groups are respectively connected in parallel with a power grid, the protection principle is the same, the protection principle is explained by the automatic operation of the first group, and the protection principle is the same in the manual operation:

the overcurrent protection principle is as follows, when a main breaker QF0 is switched on, a main power supply QF1 small-sized breaker is switched on, then QF6, QF7, QF8, QF9, QF10 and QF11 small-sized breakers are switched on in sequence, when three-phase display of a voltmeter is normal, a change-over switch QB1 is switched to an automatic switching gear, and when a controller KZQ1 detects a reactive demand signal. The junction point 105 is automatically connected, the intermediate relay KA1 is controlled to be electrified, normally open nodes 101 and 121 of KA1 are closed, a switching contactor coil KM1 is electrified, normally open nodes 101 and 137 of KM1 are closed, and the contactor is normally put into operation. At the moment, an ammeter PA1 collects the three-phase current value of the operating branch through a mutual inductor TA 1-3. When the current value of any phase exceeds the limit value of the designed rated current value of the branch, instantaneous or reverse delay action can be set through an ammeter PA1, PA1 meter is closed at a normally open node (C) to control an intermediate relay (KA 5) to be electrified, a first group of over-current indicator lamps (HL 6) are lighted, meanwhile, KA5 normally closed nodes (121 and 123) are disconnected, a switching contactor coil (KM 1) is de-electrified, KM1 is disconnected in a closed state, a contactor is cut off, and over-current protection action is completed. After the fault is eliminated, the device can be reset manually or set to be automatically reset to wait for next protection.

The principle of open-phase and three-phase imbalance protection is as follows, after the controller KZQ1 detects the reactive demand signal. The junction point 105 is automatically connected, the intermediate relay KA1 is controlled to be electrified, normally open nodes 101 and 121 of KA1 are closed, a switching contactor coil KM1 is electrified, normally open nodes 101 and 137 of KM1 are closed, and the contactor is normally put into operation. At the moment, an ammeter PA1 collects the three-phase current value of the operating branch through a mutual inductor TA 1-3. When the current value of any phase fluctuates and changes, if the three-phase unbalance limit value (the three-phase unbalance limit value is 100% × (maximum value-minimum value)/maximum value) is larger than a certain set range, the three-phase unbalance limit value range is 0-100%, if the three-phase unbalance limit value is usually set in the range of 0% -10%, similarly, when the phase loss occurs, the phase current is 0, and according to the three-phase unbalance limit value algorithm, the unbalance value is 100% (the three-phase unbalance limit value is 100% × (maximum value-0)/maximum value is 100%). Considering that the unbalance or open-phase protection can be completed by one pair of normally open points of the ammeter PA1, when any one of the conditions occurs, the normally open point of the ammeter PA1

And when the contactor is closed, transient or reverse delay action can be set, the intermediate relay KA6 is controlled to be electrified, the first group of unbalanced/open-phase indicator lights HL7 are lightened, meanwhile, KA6 normally-closed nodes 123 and 125 are disconnected, the switching contactor coil KM1 is powered off, the KM1 is disconnected in a closed state, the contactor cuts off equipment, and unbalanced or open-phase protection action is finished. After the fault is eliminated, the device can be reset manually or set to be automatically reset to wait for next protection.

Meanwhile, in order to improve the utilization efficiency of the reactor, a pair of normally closed nodes 125 and 127 of the temperature control switch ST1 and a pair of normally open nodes 1011 and 171 of the temperature control switch ST3 are arranged at the gap of the reactance intermediate phase iron core. When the equipment normally operates, the control switch QF11 miniature circuit breaker is turned on, when ST1 reaches a set temperature limit value, according to actual setting, for example, 105 ℃, ST1 normally-closed nodes 125 and 127 are disconnected, a switching contactor coil KM1 loses power, KM1 is disconnected in a closed state, a contactor cuts off the equipment, and over-temperature protection of a reactor is completed. When the temperature drops below 105 ℃, the temperature control nodes 125 and 127 of ST1 are switched from off to on, and the normal operation state is recovered.

In order to avoid the reduction of the utilization rate of equipment caused by frequent over-temperature protection actions of the reactor and the influence of frequent start-stop on the equipment, a pair of normally- open nodes 1011 and 171 of a temperature control switch ST3 is added, and the temperature limit value is set according to the real setting, for example, the temperature is set at 60 ℃. Before the over-temperature protection of the reactor, when the temperature of the temperature control switch ST3 reaches 60 ℃, normally open nodes 1011 and 171 are closed, an intermediate relay KA9 is electrified, normally open nodes 1011 and 173 of KA9 are closed, fans MF3 and MF4 run to forcibly radiate the reactor, and the phenomenon that the reactor is continuously heated to the over-temperature protection limit value, such as 105 ℃ is slowed down or prevented. When the temperature of the temperature-controlled switch ST3 falls to below 60 ℃, the nodes 1011 and 171 are switched from closed to open, the intermediate relay KA9 loses power, the nodes 1011 and 173 of the KA9 are switched from closed to open, and the fans MF3 and MF4 stop running. Therefore, the frequency of the over-temperature protection action of the reactance is effectively delayed or reduced, the utilization efficiency of the reactance is improved, and the waste of the operation of the fan is reduced.
