How to better check the diesel generator set automatic start power supply and automatic shutdown is reliable? Whether the insulation resistance and insulation strength of diesel generator set meet the requirements. Phase sequence requires that the phase sequence of terminal block of unit control panel should be arranged from left to right or from top to bottom when viewed from the front of control panel. The diesel generator set shall be equipped with heating device to ensure that the oil temperature and refrigeration medium temperature during emergency operation and rapid loading are not less than 15 ℃.
How to check whether the automatic start power supply and automatic shutdown of diesel generator set are reliable?
(1) Whether the unit can start automatically after receiving the operation command of automatic control or remote control.
(2) When the unit fails for the third time after automatic start, relevant signals shall be sent out;
(3) The time period from automatic start command to power supply to load shall not exceed 3 minutes
(4) After the automatic start of the unit is successful, the first load shall not be less than 50% of the rated load.
(5) After receiving the automatic control or remote control stop command, the unit shall be able to stop automatically; For the reserved units used together with the municipal power grid, when the power grid is restored, the units shall be able to switch over and stop automatically.
(6) The quality of equipment plays a key role in the market of generator sets. The quality of diesel generator sets is closely related to the conventional power consumption. High quality automatic start power supply and automatic stop function of diesel generator set is an important choice. The success rate of automatic start is not less than 99%.
(7) The no-load voltage setting value of the unit shall not be less than 95% and shall not exceed 105% of the rated voltage.
(8) The automatic supply function requires that the unit should be able to charge the running battery automatically.
(9) The unit shall have full-automatic maintenance functions such as phase loss, short circuit fault, over current flow, over speed and water temperature.
