Terminate；
(3) judge failure cause, and dealt with measure according to the reason.
It is described to judge whether cooler water inlet motor-driven valve failure problems occur, it specifically includes:
Detection Eventlog whether simultaneously occur cooler motor-driven valve fault alarm and water leakage of cooler fault alarm or
The alarm of cooler water flow failure if it is determines cooler water inlet motor-driven valve failure problems occur.
The step (3) specifically comprises the following steps:
A. the output voltage for detecting motor-driven valve power supply, if the output voltage switches standby less than the first predeterminated voltage
With power supply UPS, return step (2) is no to then follow the steps b；
B. detect whether it is continual receive the instruction from motor-driven valve control loop, if it is execute step c, such as
Fruit is no to restart and the loop-coupled power supply of motor-driven valve control, return step (2)；
C. electronic valve coil insulating resistance value is measured, if the resistance value is replaced spare less than the first preset resistance
Motor, return step (2), thens follow the steps d if not；
D. the motor-driven valve is opened and closed, and detects the motor-driven valve described in the moving process and whether there is bite situation, such as
Fruit, which exists, thens follow the steps e, if there is no return step (2)；
E. if the bite is present in the entire moving process, determine spool failure, replace spare spool, return
It returns step (2), it is no to then follow the steps f；
F. if the bite there are the times to be less than the predetermined time, and exist simultaneously if motor-driven valve crosses torque fault alarm and hold
Row step g, it is no to then follow the steps h；
G. determine the drift of stroke auxiliary contact, adjust the position of center-pole in motor-driven valve, return step (2)；
H. voltage on contact is measured during rotary electric valve, until the voltage is less than predetermined voltage, terminates rotation
Turn, return step (2).
Transformer cooler water inlet motor-driven valve fault recognition method of the invention can determine in time transformer cooler into
Water failure, and then implement troubleshooting, to ensure that the temperature of transformer is constantly in suitable range.
