Features of China slack adjuster
China slack adjuster consists of three relays. One is responsible for regulating the output voltage of the generator. It connects and separates the excitation field of the generator into different circuits through the relay contacts to control the excitation current of the generator and realize the control of the generator. The purpose of output voltage stabilization.
The first is to prevent excessive charging current. When the charging current is too large, the circuit will cause the voltage stabilizing relay and the current limiting relay to act at the same time, disconnect the generator excitation circuit, and stop the generator; the other is responsible for cutting off the charging circuit when there is a reverse current, and when there is a reverse current When the relay is activated, the charging circuit is cut off.
The adjustment method of China slack adjuster is to connect the dry battery in series with the battery and the ammeter, and connect it to the battery terminal of the adjuster. Start the engine and gradually increase the speed. When the circuit breaker contacts are closed, observe the ammeter pointer on the delayed engine.
If the ammeter pointer swings in the "+" direction, it means the closing voltage is too high and the spring tension should be weakened; if the ammeter pointer swings in the "-" direction, it means the closing voltage is low, and the spring tension should be increased. Just repeat the adjustment in this way until the pointer of the ammeter does not oscillate when the cut-off contact is closed, indicating that the closing voltage is appropriate.
