Common fault table of rectifier circuit of ukuchithwa kwesithando somlilo
No DC voltage | Rectified trigger without pulse output | Rectifier trigger regulated power supply without voltage output |
Poor contact of rectifier trigger board | ||
Whether the synchronous transformer is damaged or welded | ||
Turn off the power potentiometer | ||
The blocking protection in the regulation system is damaged | ||
DC voltage is low | Individual rectifier bridge arm KP tube has no trigger pulse | Poor contact of the connector or cause desoldering |
Partial rectifier trigger without pulse output | ||
The rectifier pulse transformer is damaged:
Pulse transformer wire disconnected Short circuit of pulse transformer secondary diode |
||
Some KP tubes have high trigger power | ||
Some KP tubes or couplers are damaged | ||
Poor contact of main circuit contactor or air switch (knife switch) |
