Environmentally-friendly coil iron traction transformer passed certification
Economic Daily News Recently, the 110 kV energy-saving and environmentally-friendly coil core traction transformer independently developed by China Railway Corporation Limited and independently developed by China Railway Electrification Bureau Industry Co., Ltd. passed the inspection and certification of the national electrical laboratory. Compared with similar products, the biggest feature of this product is low energy consumption, no-load loss is more than 40% lower than national standards, and load loss is more than 10% lower than national standards.
Analysis of six development trends of high-voltage electrical industry
With the advancement of science and technology, high-voltage electrical appliances have adopted high technology, new principles, new processes and new media, and a new generation of high-voltage electrical appliances is being brewed. The development trends are as follows:
Why should the neutral of the transformer be grounded
The transformer needs to be grounded during operation so that the transformer will not be unnecessarily damaged. Because the transformer is a high-voltage device, if you pay little attention to it in rainy days, it will affect the voltage transmission of the transformer. However, if the transformer is grounded, the voltage will be transmitted to the ground with the ground wire, which will not cause harm to the human body. So why should the neutral line of the transformer be grounded?
Detailed application range of ultrasonic partial discharge detector
Ultrasonic partial discharge detector, also known as ultrasonic inspection instrument, is a power-specific instrument that uses sound wave patterns issued by electrical equipment when abnormal discharge occurs to determine the location of a fault. It is an electric power company's power inspection and mining railway enterprise power fault troubleshooting. One of the necessary equipment for prevention has the characteristics of high sensitivity, strong anti-interference ability, accurate position for detecting abnormal discharge, convenient operation, etc. Today, the manufacturer of ultrasonic partial discharge inspection equipment will introduce in detail for everyone, its application in electric power What are the scopes.
