Specific embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent Select embodiment to be merely to illustrate and explain this utility model, be not used to limit this utility model.
As shown in figure 1, a kind of high-pressure thyristor monitors circuit, including detection circuit 1 on-line, wrap in the detection circuit 1 Include the IGCT 2 being connected in antiparallel, 2 two ends of the IGCT be connected in parallel respectively capacitive branch 3, the first measure loop 4 with Second measure loop 5, the capacitive branch 3 include the capacitor 6 being connected in series and operating resistance 7, first measure loop 4 Including the first detection resistance 8 and the first detection plate 9 that are connected in series, second measure loop 5 includes second for being connected in series Detection resistance 10 and the second detection plate 11,1 one end of the detection circuit are electrically connected with operating circuit 12, in the operating circuit 12 Including the IGCT 2 being connected in antiparallel, 2 two ends of the IGCT are connected in parallel capacitor 6 and operating resistance 7.
More specifically, 12 quantity of the operating circuit is multiple, as the problem of 2 dielectric level of IGCT can not meet High-pressure system, so current is that IGCT 2 is connected to increase dielectric level in high-pressure system, meets system requirements.
More specifically, first detection plate 9 and the second detection plate 11 are model of the same race, the electricity of the first detection resistance 8 Resistance value of the resistance more than the second detection resistance 10, different voltages occur in 2 two ends of IGCT sends can different detection plates Signal.
More specifically, the capacitor 6 is detected with operating resistance 7, the first detection resistance 8 and the first detection plate 9, second Annexation between resistance 10 and the second detection plate 11 is electric connection, simplifies the equipment of detection, reduces cost, subtracts Space is used less.
Utility model works principle:When 2 two ends of IGCT do not have voltage, the first detection plate 9 and the second detection plate 11 Signal do not send all without being lit, judges to be gone wrong by IGCT 2 simultaneously, IGCT 2 is shorted without voltage difference;When There is voltage at 2 two ends of IGCT, but can only light the second detection plate 11, as the resistance value of the first detection resistance 8 is more than second The resistance value of detection resistance 10, by the electric current of the first detection plate 9 it is little be lit can not which, at this moment judge IGCT 2 all It is good;When there is voltage at 2 two ends of IGCT, and the first detection plate 9 can be made to be lit with the second detection plate 11, judge other certain Only or some IGCTs 2 there is a problem, system partial pressure IGCT 2 is reduced and makes other 2 both end voltages of IGCT become many, including 2 partial pressure of IGCT of measure loop becomes many, and it is which IGCT 2 goes wrong that at this moment can detect bottom one by one with circuit tester.
It is this utility model preferably embodiment above, this utility model those skilled in the art can also be to upper State embodiment to be changed and changed, therefore, this utility model is not limited to above-mentioned specific embodiment, every ability Field technique personnel made on the basis of this utility model it is any conspicuously improved, replace or modification belong to it is practical New protection domain.
