[Maintenance of voltage stabilizer]How to maintain the voltage stabilizer daily maintenance method of the voltage stabilizer
The voltage stabilizer is a device that stabilizes the output voltage. The voltage stabilizer is composed of voltage stabilizer and constant voltage, control circuit, and servo motor. With the rapid advancement of society, the number of electrical equipment and daily increases. The phenomenon of voltage instability occurs frequently, and voltage stabilizers are increasingly being demanded by enterprises, factories, homes, engineering construction and other places. Therefore, how to maintain and maintain the voltage stabilizer in daily use is extremely important.
How to maintain the voltage stabilizer
(1) Always observe whether the cooling fan and transmission mechanism of the voltage stabilizer are operating normally, and check whether the input voltage and load are not If it exceeds the rated range, if any abnormality is found, deal with it in time
(2) Carefully clean all parts, especially the carbon brushes, contact the exposed parts of the regulator, and remove dirt
(3) Check the interior Check whether the parts and wire ends are loose. For those with weak connection or poor contact
(4) Replace worn or damaged carbon brushes in time, and repair or replace any faulty or damaged components in time
Maintenance and repair method of voltage stabilizer
Phenomenon: main switch trips
Reason: excessive load Phase loss protection; Neutral disconnection; Overvoltage protection
Treatment method: Check whether the load is too large; Check whether the input terminal is missing phase; Check whether the neutral line is open; The rated voltage is 10%, if it exceeds it is normal.
Symptom: output voltage is too low
Reason: input voltage is too low; transmission mechanism is stuck; control Failure
Treatment method: check whether the input voltage is lower than the rated input voltage; notify the agent or manufacturer; notify the agent or manufacturer
phenomenon: the output voltage is too high
strong>
Cause: input voltage is too high; transmission mechanism is stuck; control failure
Treatment method: check whether the input voltage exceeds the rated input voltage; notify the agent or manufacturer; notify the agent Manufacturer or manufacturer
Phenomena: the ammeter does not display
Reason: the load is too small
Solution: the voltage stabilizer is normal
p>
Phenomena: The voltmeter does not display
Cause: No output voltage
Solution: Check whether the voltmeter is burnt
Phenomena: The voltage regulator has sparks
Treatment method: re-polish the surface of the voltage regulator with O-size sandpaper; check whether the components of the carbon brush move freely and the spring pressure Is it enough?
Reason: Poor contact of the regulator carbon brush
Symptom: The regulator emits smoke
Reason: Internal components Serious damage
Solution: stop running immediately and notify the agent or manufacturer
