Abstract

The invention relates to a heat-resisting shield test electrode and an experiment facility with the test electrodes. The test electrode comprises a thermal conductor used for lining in at least a partof the structure of heat-resisting shield clothing to support the clothing; and the thermal conductor is provided with multiple temperature sensors. The thermal conductor comprises a first conductorused for lining in the gloves of the heat-resisting shield clothing to be formed into a hand shape structure. When in experiment, the gloves of the heat-resisting shield clothing are arranged on the test electrodes of the hand shape structures in a sleeving manner, then palm surfaces are tightly attached on heating electrodes, the changing situation of the temperature along with time is recorded according to readings fed back to a temperature measurer by the temperature sensors, and experimental results are detected and recorded; and then the backs of hands are tightly attached to the heatingelectrodes, the changing situation of the temperature along with the time is recorded according to readings fed back to the temperature measurer by the temperature sensors, and the experimental results are detected and recorded.

Description

Technical field [0001] The invention relates to a heat-resistant shielding clothing test electrode and an experimental device with the test electrode, which can be used to detect the thermal insulation performance of the heat-resistant shielding clothing for live working of ground electrode lines. Background technique [0002] The grounding electrode overhead line needs to pass the rated load current of the entire UHV DC transmission system under the single-maximum operation mode. Therefore, the general grounding electrode line uses heat-resistant wires to improve the current capacity of the grounding electrode line. The heat-resistant wire improves the operating temperature level of the wire. With the same conductor cross-sectional area, it can transmit more electricity than the traditional steel core aluminum stranded wire. The rated current of DC transmission lines generally reaches thousands of amperes. When the system is in single-maximum operation, the current flowing throu...

Problems solved by technology

[0005] This method has the following disadvantages: When live workers perform maintenance work near heat-resistant wires, it is mainly the hands, elbows, arms and other parts that are most likely to touch high-temperature wires, so the test and detection should be aimed at these parts during actual work. Under the circumstances that may touch the wire to be heated, the layout test should be carried out, that is, the glove and sleeve should be heated outside, and the temperature rise should be measured inside, etc.

However, the area of ​​the heating plate is large, and the test is mainly for the overall part of the shielding suit. At the same time, the shielding suit is laid flat on the heating plate. The measured temperature rise is the situation after the heat insulation effect of the double-layer shielding suit, which is not realistic.
