China Southwest Net/News Zhong Jiabin and reporter Shen Guannan report: On April 18, the first UHV transmission line passing through Jiangxi-Sichuan Yibin to Zhejiang Jinhua ±800 kV UHV transmission line began an annual power outage maintenance , Before the summer electricity peak, a comprehensive "physical examination" is carried out in advance, and 10 sets of lightning arresters are installed for the first time to improve the lightning protection ability of the line and ensure the safe operation of the line. It is reported that the ±800 kV Binjin Line UHV transmission line starts from Yibin in Sichuan in the west to Jinhua in Zhejiang in the east, with a total length of 1670.8 rated value, rated voltage level of ±800 kV, and transmission power
Recently, according to customer reports, the products sold on a website are the same as Shuguang fuses, but the price difference is large. ? So we plan to learn CCTV and get a XRNP1-10KV 0.5A fuse from a friend for disassembly. Next, we will do a product anatomy for you, and show you the mystery.
In the past ten years, in the planning of low-voltage power distribution systems for industrial buildings, civil buildings and outdoor equipment, the use of low-voltage fuses has become less and less, but thousands of people have used low-voltage circuit breakers. Correspondingly, low-voltage The number of fuses installed in the distribution box is also greatly reduced.
According to the requirements of safety production standardization standards for small and micro enterprises in relevant industries, 13 enterprises including Wenzhou Shuguang Fuse Co., Ltd. have passed the comprehensive assessment of the safety production standardization of small and micro enterprises, and meet the requirements of the safety production standardization of small and micro enterprises. It is hereby announced.
The jet fuse is to install the melt in an insulating tube made of solid gas-producing materials. The solid gas-generating materials can be electrical reverse white cardboard or plexiglass materials. When the short-circuit current passes through the melt, the melt immediately melts and generates an arc. The high-temperature arc quickly decomposes the solid gas-generating material to produce a large amount of high-pressure gas, thereby fully insulating the ionized jet fuse, improving the insulation of the distribution network and reducing accidents. rate. Especially the urban distribution network completely solves the traditional guarantee of the effectiveness of the electrical performance of the equipment, and avoids the problem of the insulation resistance drop caused by the fuse due to fouling.
