Problems solved by technology

This method is only suitable for voltage levels below 35kV. When the voltage level increases, the number of thyristors required increases, and the signal of breakdown return will also increase. The number of receiving optical heads on the bus board is limited, which cannot meet the dynamic reactive power requirements of high voltage levels. The need for compensating devices

Abstract

The invention relates to a breakdown detection device for a power unit of a photo-thyristor. The breakdown detection device comprises a power panel, a breakdown detection subordinate expansion board, a breakdown detection plate AB1, a breakdown detection plate AB2, a breakdown detection plate BC1, a breakdown detection plate BC2, a breakdown detection plate CA1, a breakdown detection plate CA2 and a breakdown detection bus plate. The power panel, the breakdown detection subordinate expansion board and the six breakdown detection plates are all inserted in the breakdown detection bus plate. Multi-film single-core optical fibers are adopted between the breakdown detection device and the power unit, so the breakdown detection device is higher in work stability, reliability and anti-interference performance; through the additional arrangement of the breakdown detection subordinate expansion board, an expansion function is achieved; the breakdown detection device can be used for monitoring the working state of the photo-thyristor in real time, and when a certain photo-thyristor is damaged, the breakdown positions and breakdown numbers can be displayed timely and accurately on a control cabinet; the breakdown detection device ensures that a whole system will not be damaged when part of the SVC back-out system is damaged, and enables each part of the system to operate reliably.

Description

technical field [0001] The invention relates to a breakdown detection device for a direct light-triggered thyristor power unit, which is applied to electric power, metallurgy and all other fields using light-controlled thyristors as core devices. Background technique [0002] Direct light-triggered thyristors, namely light-controlled thyristors, are the most widely used valve components at present. The power units of dynamic reactive power compensation devices are composed of light-controlled thyristors. The control system can continuously adjust the impedance by controlling the trigger angle of light-controlled thyristors, which can enhance It can improve the power transmission capacity of the system, improve the stability of the power system, and has the functions of damping power oscillation, suppressing subsynchronous oscillation, and compensating power factor. The triggering of the direct photothyristor power unit is an important part of the dynamic reactive power compe...
