Summary:The invention discloses a method for detecting temperature characteristics of a thermoswitch. The method comprises the steps of: arranging five oil grooves, namely an action upper limit oil groove, anaction lower limit oil groove, a reset upper limit oil groove, a reset lower limit oil groove and a detection oil groove, and ensuring that an oil temperature in the detection oil groove is 15-25 DEGC lower than an action lower limit temperature; putting the thermoswitch into the action lower limit oil groove, and keeping the temperature constant for 5-8 minutes; putting the thermoswitch into the detection oil groove, disconnecting a test contact to obtain a first batch of qualified thermoswitches, putting the qualified thermoswitches into the action upper limit oil groove, and keeping the temperature constant for 5-8 minutes; taking out and putting the qualified thermoswitches into the reset upper limit oil groove, and keeping the constant temperature for 5-8 minutes; taking out the thermoswitches, putting the t
