Summary: | Provided is a temperature rise online monitoring device of a high-voltage device cable connector. The temperature rise online monitoring device comprises an A-phase temperature acquiring circuit, a B-phase temperature acquiring circuit, a C-phase temperature acquiring circuit, a environment temperature acquiring circuit, a microprocessor, a display circuit, and a power supplying circuit. The three phases of temperature acquiring circuits and the environment temperature acquiring circuit are successively and correspondingly connected with four A/D interfaces of the microprocessor. The I/O port of the microprocessor is connected with the input port of the display circuit. The output port of the power supplying circuit is connected with the power end of the microprocessor. The power supplying circuit comprises a rectifying circuit, a filtering circuit, a voltage stabilizing circuit, and an energy storing circuit. The device is capable of correctly determining the temperature rise change case of the copper conduc |
