Yuchai Diesel Generator Set Voltage is Lower Than Rated Voltage

Yuchai diesel generator set protection function test Overspeed protection function test, over-current protection test, test, etc. Overvoltage protection test When a certain over-voltage occurs on Yuchai diesel generator set, the voltage protection device will alarm when it exceeds 10% of the rated value and 15% of the rated value. When it is close, the test of Yuchai diesel generator set is simulated or adjusted.

When the voltage of Yuchai diesel generator set is less than 0.85 times of the rated voltage, the voltage protection device shall be able to alarm. When the voltage of Yuchai diesel generator set is lower than 0.7 times of the rated voltage, the voltage protection device shall be able to alarm and stop the protection, and test with simulation method or voltage regulator.

Overheating protection function: the short-circuit protection test of Yuchai diesel generator set can be completed through the short-circuit protective relay or circuit breaker. When a three-phase, two-phase or single-phase short circuit suddenly occurs outside the power station, the short circuit point shall be removed from the Yuchai diesel generator set to protect the Yuchai diesel generator set. The test can be carried out on a circuit breaker whose capacity is two or more stages larger than the unit circuit breaker.

When Yuchai diesel generator operates continuously under rated conditions, it shall continuously monitor and check whether the lubricating oil pressure/oil temperature/cooling water temperature of Yuchai diesel generator are at normal values.

Yuchai diesel generator is allowed to operate continuously under rated conditions. It shall be monitored continuously and checked every 30 minutes. The lubricating oil pressure of Yuchai diesel generator is generally 350-600 kPa, which should not be lower than 300 kPa.

The lubricating oil temperature of Yuchai diesel generator is generally between 60 ℃ and 150 ℃. The temperature should be stable after 1 hour of full load stable operation. The cooling water temperature of Yuchai diesel generator is generally between 70 ℃ and 95 ℃. Check the noise and leakage of Yuchai diesel generator body and accessories. If there is any abnormal noise, stop the inspection immediately and eliminate it.
