Description
Technical field
The present invention relates to high-voltage commutation field, especially current conversion station valve tower thyristor alignment system.
Background technology
Thyristor is a kind of switch element, he typically is provided with following characteristic：
1st, when thyristor bears reversed anode voltage, no matter which kind of voltage gate pole bears, thyristor is all in reverse blocking state；
2nd, when thyristor bears positive anode voltage, only in the case where gate pole bears forward voltage, thyristor just turns on.At this moment
Thyristor is in forward conduction state, and here it is the lock properties of flow of thyristor, you can control characteristic；
3rd, thyristor is in conducting, as long as there is certain positive anode voltage, no matter gate voltage, thyristor is kept
Conducting, i.e., after turn on thyristors, gate pole is ineffective.Gate pole only plays trigger action；
4th, thyristor works as main circuit voltage in conducting（Or electric current）When being reduced to close to zero, thyristor shut-off.
Based on above-mentioned four kinds of characteristics, thyristor is widely used in whole in super-pressure or extra-high voltage direct-current transmission engineering
Stream station（Alternating current is changed into direct current）Or Inverter Station（Direct current is changed into alternating current）, to complete alterating and direct current it
Between mutual conversion.
