(1) Leakage of compressor: mainly because of serious vibration,
the motor coil of compressor contacts with the shell, the coat of
enameled wire will come off some where and connect with shell.
Other reasons may be over voltage, insufficient of voltage,
adverse circumstances (temperature too high, ventilation and
heat radiation to bad) for freezer, thermal protection unit out of
order, etc. They will make the motor coil over temperature,
insulation material loose, insulation is damaged then electricity
will occur.
(2) Leakage of motor connection terminals: the connection
terminals of fully enclosed compressor are made from high
temperature soda glass sintered ceramics, around the terminals
are filled with a high polymer. The terminals and insulation
material must have the same linear expansion coefficient, the for
requirement between terminals and the shell is more than 0.5
million ohm. The reason of terminal leakage is that soda glass is
broken or there are conductive materials such as water, dirt, etc.,
adhered to terminals.
