Current conversion station valve tower thyristor alignment system and its method of work
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.
Such as Fig. 1(a)It is single thyristor shown in red frame, the voltage that can bear is limited, in order to meet engineering demand,
Generally multiple thyristors are combined to form valve section with certain specific arrangement mode, if then dryvalve section is combined to form valve tower, such as
Fig. 1 (b).The main device component of valve tower is formed as thyristor, but also comprising other is simultaneously the necessary parts met needed for operating mode.
In one ultra-high voltage converter station, thyristor total amount is at 2900 or so, and branch is in 4 24, valve Room valve towers.The valve Room such as Fig. 1
(c)It is shown.
In normal operation, the thyristor that each valve tower is installed contains redundancy, i.e., when event occurs in the thyristor of 3 or so
During barrier, valve tower remains to normal operation.More than this redundancy, it is necessary to direct current transportation of stopping transport immediately.Therefore thyristor is as the change of current
Stand core component, can normal operation be directly related to the stability of extra-high voltage direct-current transmission.When abnormal accuse occurs in thyristor
, it is necessary to determine the position of thyristor with the most fast time when alert, by infrared measurement of temperature etc. detection means to be aided in determine it
Whether it is abnormal.
Since thyristor is large number of, and the thyristor scene arrangement mode produced between different manufacturers is without pervasive
Property.Therefore, there are the following problems for thyristor positioning at present:
1st, thyristor warning message in backstage is ciphertext, and operation maintenance personnel needs warning information passing through complicated method migration Cheng Ming
Literary information could obtain the location information of thyristor, and conversion method is complicated, it is necessary to which the time learns, and easily forgets, transfer process
It loses time easily to malfunction.
