State Grid Yulin Power Supply Company puts the pulse diagnosis grid equipment to build a firm grid security barrier

"468 Sour Erhai Sea Switch Cabinet Cabinet In the middle of the cabinet, the local discharge detection data is 26DB, the equipment is normal, please record it." On September 25, the charging testing class of the State Grid Yulin Power Supply Company was in 110 kV The Xiyongdun Transformation Power Station conducts a charging detection of the entire station equipment. This is the 18th substation of the company's charging detection since the company's autumn examination.

In order to ensure the safe and reliable operation of the power grid equipment during the peak winter, the State Grid Yulin power supply company made full use of the autumn inspection timing, solidly carried out system equipment charging detection and safety inspections, and was a "doctor" for the safe and stable operation of the power grid equipment. In order to ensure the effectiveness of this work, deploy in advance, strengthen the professional skills training of staff, and master the use methods and precautions of detection instruments. During the local discharge and charging detection of the switch cabinet, the staff strictly implemented the on -site work requirements, close the test instrument on the wall of the cabinet, and use the detection methods such as ultrasonic, high -frequency, and temporary ground voltage. Accurate judgment. In infrared precise temperature measurement work, the staff strictly abide by the accurate temperature measurement conditions in response to the distribution of load distribution in the jurisdiction, focusing on the temperature and registration of equipment such as voltage transformers, lightning arrangers, and supportable insulators, and accurately grasp the "health" operation of the equipment situation.

"During the operation, the device can sign the characteristics of" sound, light, heat, electromagnetic ". We can monitor through these characteristics. High -frequency local discharge detector, multi -functional local discharge detector and other portable instruments are particularly possible Aiming at the characteristics of GIS device's local discharge defects with strong hiddenness and long gaps in discharge, it can accurately judge and discover equipment defects. "Zhang Yuanyuan, a charging test class, said.

As of now, the State Grid Yulin Power Supply Company has completed the equipment band -testing of 23 110 kV transformation stations and 3 35 kV power stations within the scope of operation and maintenance. In the next stage, the remaining substation will be carried out on the remaining substation, and the test data will be compared with the test data of the test data graphs, other phase or intervals of the test data, and other types of similar devices of the test data map, other phase or interval. The type and severity make precise judgments, and effectively discover and deal with the hidden dangers of equipment in time. During the peak winter, the grid in the area is escorted stably.
