What is the reason for the high frequency after the intermediate frequency is started
Fault phenomenon: It can be started. After successful start, the frequency is much higher than the original, and sometimes it is not easy to start.
Fault analysis and treatment: This is mostly a load problem.
A. There is a short circuit between turns of the load coil, which may overlap between wires or have conductive iron filings, copper wires, etc.
B the load capacitor has an open column, or the capacitor connection line has a serious ignition, resulting in changes in internal capacity.
