Description

Technical Field

[0001] The invention belongs to the technical field of power equipment maintenance, and in particular relates to a current transformer insulation discharge pulse detection device. Background Art

[0002] With the rapid development of the national economy, the national power industry has also made great progress. The stability of the power system is of great significance to the stable development of the economy. Current transformers are indispensable and important equipment in the power system, realizing the protection, measurement, and metering of the power grid. Most current transformers have the advantages of fast heat dissipation, uniform conduction, and good insulation. The quality of the insulation of the current transformer will directly affect the safe use of power equipment. Oil-paper insulation is the main form of current transformer insulation. Since the current transformer is in a high voltage and high current operating environment for a long time, it is easily affected by adverse effects such as impact loads, which causes the oil-paper insulation to gradually age and its insulation performance to decline. When most electrical equipment fails or has hidden dangers, its characteristic parameters such as color spectrum, temperature rise, and partial discharge will change accordingly. The most sensitive indicator is partial discharge. Detecting the partial discharge pulse of insulating oil paper has become an effective means to judge and evaluate its status. The existing pulse detection equipment requires the staff to clamp it directly on the outside of the cable with their hands, which has a large safety hazard, and the unstable clamping force can easily damage the cable.
