Description

High-power phase control rectifier switching on/off circuit
Technical field
The invention relates to high-power phase control rectifier switching on/off circuit, is used for the reliable on off control that carries out to high-power phase control rectifier circuit.
Background technology
According to the characteristics of high-power phase control rectifier circuit, its action meeting that starts and stop of closing a floodgate causes the impact of closing a floodgate to prime switch and rear class electric capacity.For the normal startup of safeguards system, must guarantee: when closing a floodgate startup, start first the voltage stabilizing major loop, rear startup phase-shift control circuit carries out phase shifting control; When stopping, stopping first phase-shift control circuit, after stop the voltage stabilizing major loop.This startup and the mode that stops can be avoided prime switch trip that the false triggering by pulse causes and to the impact of rear class electric capacity.In the prior art, can realize above-mentioned startup and stop the switching on/off circuit complicated structure of mode that cost is higher.
Summary of the invention
The invention realizes high-power phase control rectifier circuit is carried out reliable on off control with simple circuit structure and cheap cost, guarantees that the voltage stabilizing major loop starts prior to phase-shift control circuit, and phase-shift control circuit stops prior to the voltage stabilizing major loop.
Provide high-power phase control rectifier switching on/off circuit for this reason, comprise master control branch road, phased branch road, master control A.C. contactor, phased A.C. contactor, master control starting switch QA1, phased starting switch QA2, master control shutdown switch TA1 and phased shutdown switch TA2,
The coil J1 of master control A.C. contactor is serially connected in the master control branch road, and it gets the electric voltage stabilizing major loop of then connecting, and its dead electricity then disconnects the voltage stabilizing major loop,
The coil J2 of phased A.C. contactor is serially connected in the phased branch road, and it gets the electric phase-shift control circuit of then connecting, and its dead electricity then disconnects phase-shift control circuit,
It is characterized in that,
Master control starting switch QA1 and phased starting switch QA2 are the open type point driving switch, and master control shutdown switch TA1 and phased shutdown switch TA2 are the closed type point driving switch,
Connect with master control starting switch QA1 behind master control branch road and the phased branch circuit parallel connection, the normally opened contact J1-1 of master control A.C. contactor master control starting switch in parallel QA1,
In the master control branch road, master control shutdown switch TA1 connects with the coil J1 of master control A.C. contactor, the normally opened contact J2-1 of phased A.C. contactor master control shutdown switch in parallel TA1,
In phased branch road, phased starting switch QA2, phased shutdown switch TA2 connect with this three of coil J2 of phased A.C. contactor, the normally opened contact J2-2 of phased A.C. contactor phased starting switch QA2 in parallel.
From initial condition as shown in Figure 1, the crawl master control starting switch QA1 of elder generation can make the coil J1 of master control A.C. contactor get electric, connected on the one hand the voltage stabilizing major loop, make on the other hand normally opened contact J1-1 closed, master control starting switch QA1 reverts to and disconnects but normally opened contact J1-1 that its effect under closure state has been in parallel replaces subsequently; Then that the coil J2 of phased A.C. contactor is got is electric for the phased starting switch QA2 of crawl, has connected on the one hand the voltage stabilizing major loop, has both relied on the other hand to make that normally opened contact J2-2 is closed to realize self-locking, makes again normally opened contact J2-1 closed, so far is operating state.Under initial condition, even operate miss, the elder generation crawl phased starting switch QA2, this moment is because master control starting switch QA1 and normally opened contact J1-1 disconnect, so the closure of phased starting switch QA2 can not make the coil J2 of phased A.C. contactor get electric, phase-shift control circuit just can not start prior to the voltage stabilizing major loop, subsequently because phased starting switch QA2 reverts to disconnection, so crawl master control this moment starting switch QA1 can make coil J2 that the coil J1 of master control A.C. contactor gets electric and phased A.C. contactor temporarily not electric, thereby guaranteed that the voltage stabilizing major loop starts prior to phase-shift control circuit.
From above-mentioned operating state, the phased shutdown switch TA2 of elder generation's crawl can make the coil J2 dead electricity of phased A.C. contactor, disconnected on the one hand phase-shift control circuit, normally opened contact J2-2 and normally opened contact J2-1 are disconnected, and phased shutdown switch TA2 reverts to closure but notes that normally opened contact J2-2 disconnects subsequently; Then crawl master control shutdown switch TA1 can make the coil J1 dead electricity of master control A.C. contactor, has disconnected the voltage stabilizing major loop on the one hand, and normally opened contact J1-1 is disconnected, and so far gets back to from initial condition as shown in Figure 1.Lower in working order, even operate miss, the elder generation crawl master control shutdown switch TA1, this moment is because normally opened contact J2-1 disconnects, so the disconnection of master control shutdown switch TA1 can not make the coil J1 dead electricity of master control A.C. contactor, the voltage stabilizing major loop just can not stop prior to phase-shift control circuit, subsequently because master control shutdown switch TA1 reverts to closure, the temporary dead electricity not of the coil J1 of master control A.C. contactor so crawl phased shutdown switch TA2 this moment can make the coil J2 dead electricity of phased A.C. contactor, thus guaranteed that phase-shift control circuit stops prior to the voltage stabilizing major loop.
The invention by the master control A.C. contactor be connected the ingenious connection of contact of A.C. contactor, realize high-power phase control rectifier circuit is carried out reliable on off control with simple circuit structure and cheap cost.
