Method for judging aging degree of insulation of XLPE cable connector based on dynamic heat source

A method for judging aging degree of insulation of a cable T-connector based on a dynamic heat source, comprising the following steps:

• S1, constructing a temperature rise verification test platform of the cable T-connector, and simulating heating of a cable core by using a controllable heat source;
• and
• S2, using the constructed temperature rise verification test platform to study influence of different thermal conductivity of an insulation layer on internal and external temperature responses of the cable T-connector, comparing temperature responses of inner and outer skins of the cable T-connector in different states by experiments under a same internal heat source temperature change, and fitting temperature response curves of the inner and outer skins to obtain a phase angle difference, so as to judge a corresponding relationship between aging degree and heat transfer capacity according to the phase angle difference of the cable T-connector with different aging degrees;
• and
• wherein the method further comprises:
• based on the judged aging degree of the insulation of the cable T-connector, generating an alert signal indicative of the aging degree and outputting the alert signal indicative of the aging degree;
• and
• based on the alert signal indicative, automatically adjusting an operating parameter of a power system associated with the cable T-connector to prevent cable failure.
