Summary:The invention discloses a sealing method for preventing impregnating varnish from passing through a joint of a refrigeration motor outgoing line and a motor winding. The method comprises the following steps of: 1) coating a sealgum layer on the refrigeration motor outgoing line to be sealed; 2) sleeving a heat shrinkable tube on the refrigeration motor outgoing line which is to be sealed and is coated with the sealgum layer; and 3) heating the heat shrinkable tube to make the heat shrinkable tube radially shrink until the inner wall of the heat shrinkable tube is closely pressed on the sealgum layer coated on the refrigeration motor outgoing line to be sealed. The invention solves the problems in the prior art and provides the sealing method for preventing the motor outgoing line from hardening with varnish and influencing or breaking the motor.
