An on-line temperature monitoring method for T type cable joint of ring network cabinet based on improved thermal circuit model is proposed. The method can calculate the temperature of internal conductor by measuring the T type insulation sheath and the ambient temperature. A test platform is built for simulating the real running condition of T type connector in the ring network cabinet. The correctness of the thermal circuit model is verified by comparing the measured values with the calculated values. The results show that when the temperature field is in the steady state
the temperature relative error stays within 5. 4 %. When the temperature field is in the transient state
the temperature relative error stays within 9. 0 %. The thermal circuit model can monitor the temperature of cable joints in real-time
the safe operation of the ring network cabinet and cable line can be ensured.
