Abstract

The invention discloses an insulating material electrical aging test system, which comprises a control device, a temperature acquisition device and a plurality of aging sample measurement devices. Theaging sample measurement devices are used for connecting a high-voltage power supply to test the temperature of a resistor corresponding to an insulating material sample in real time and sending thetemperature to the temperature acquisition device; the temperature acquisition device is used for acquiring the temperature fed back by each aging sample measurement device in real time; the control device is used for controlling the aging test sample measuring device to disconnect from a high-voltage power supply when the temperature change value between the temperature of any aging test sample measuring device at the current moment and the temperature of the aging test sample measuring device at the previous moment is greater than or equal to a preset temperature change threshold value. Thus, an electrical aging test loop for a plurality of insulating material samples is formed. According to the electrical aging test system for the insulating material, provided by the invention, the electrical aging field intensity can be prevented from being frequently cut off, so that the electrical aging performance test result of each insulating material sample is more accurate.

Description

technical field [0001] The invention relates to the technical field of high voltage, in particular to an electrical aging testing system for insulating materials. Background technique [0002] Power cables can provide stable and reliable power transmission, and are the key channels for power supply. Power cables most widely use polymer materials as the insulating layer. Under the long-term electric field, the polymer insulating material is prone to electrical aging, which leads to the gradual degradation of the polymer material and eventually causes the breakdown of the insulating layer. Therefore, the polymer electrical aging The behavior has an important impact on the long-term working stability of power cables, and the research and development of polymer insulating materials should also pay full attention to their electrical aging performance. However, the evaluation of the electrical aging performance of polymer insulating materials and the prediction of the electrical ...
