Today, we will briefly introduce the problem of fault inspection of blown fuse or disconnected thermal relay when the generator set is started. Troubleshooting steps. Check whether the fuse capacity of the generator set is appropriate, if it is too small, you can change it and try again. If the fuse continues to blow, check whether the drive belt is too tight or the load is too large, whether there is a short circuit in the circuit, and whether the motor itself is short circuited or grounded. Ground fault checking method. Use a megohmmeter to measure the insulation resistance of the motor winding to ground. When the insulation resistance is lower than 0.2MΩ, it means that the winding is seriously damp and should be dried. If the resistance is zero or the calibration lamp is close to normal brightness, the phase is grounded. Winding grounding generally occurs at the outlet of the motor, the inlet hole of the power line or the winding extension slot. For the latter ca...
