Although the generator AVR is a non-wearing part, it is abnormally damaged due to various reasons. Under the condition that all parts from the engine to the generator are in good condition, we can adopt temporary emergency measures to solve the problem of urgently needing electricity when the power cannot be generated due to AVR damage.
(1) Cancel AVR plate and only use F1 and F2 as temporary excitation input terminal; As shown in figure
(2) With the help of the battery of the generator, add an excitation switch and 5W and 5K ovariostat. When it is not in operation state, let the switch be in the closed state. Turn on the switch after the engine reaches the rated speed to establish the voltage and adjust the rheostat to set the voltage at about 420V; If there is a voltage regulator on the control panel of the generator, it is temporarily used to stabilize the voltage by modifying the wiring.
(3) Not all states can use the above method of power supply, objective existence must meet the following conditions to meet the use requirements: A, load ≤70%; B. Load ≤20%;
(4) This method should pay attention to whether the charging performance of the charger is good. If the charger can not be charged, add another 24V transformer of more than 20A, and use the battery in parallel after the whole, otherwise the battery will soon run out of electricity.
