Volvo diesel generator set safe operation rules and matters needing attention during drying

I. Safe process operation rules for generators

1, the fixed generator should be installed in the room, the bottom must be firm, the mobile generator should put the foot pad solid stable, and set up an awning.

2. Fireproof equipment such as sand box or dry fire extinguisher is set near the body.

3. The conductor from the generator to the distribution board or to all electrical equipment must be well insulated and the joint should be firm.

4. All parts should be checked before starting. During operation, it is forbidden to work on the line and touch the high-voltage line or clean it by hand.

5, after the maintenance of the generator, before the start of operation, must check whether there are tools or other objects left between the rotor and the stator.

Ii. Precautions when drying

Heating and drying should be carried out in clean air, and the generator should be blown clean with compressed air before drying. If the winding is seriously damp, it needs to be dried by hot air first. After a certain period of drying, it should be dried with load to avoid the breakdown of insulation.

When drying, should put more thermometers, distributed in each part of the generator, in order to master the temperature of each part, to prevent local overheating. If the drying temperature does not reach the required temperature, it can be dried at a slightly lower temperature, but the time should be appropriately extended.

Temperature and insulation resistance should be measured every 30 minutes after drying begins. When the temperature is stable, the temperature should be measured every 1-2h and recorded. At the early drying stage of Marine diesel generator set, due to heating of windings, water evaporates out, making insulation resistance decrease, and then gradually rise, the rising speed becomes slower and slower, and finally stable at a certain value.
