Invention patent certificate number | ZL201110195740.1 |
The first domestic on-board integrated 500kV transformer field calibration system
Through long-term research and accumulation, Suzhou Huadian has formed four types of products in the field of high-voltage measurement equipment: 1. High-stability AC and DC high-voltage power supplies; 2. High-precision digital kilovolt meters; 3. Standard transformers and transformer calibration Inspection of complete sets of equipment; 4. On-site inspection of transformers. It has been widely used in the national electric power research institutes and the measurement centers of the provincial technical supervision bureaus. In accordance with the requirements and specifications of the State Grid Corporation's Electric Energy Metering Center, Suzhou Huadian will provide complete supporting equipment and intelligent package solutions for the comprehensive development of high-voltage metering work in the power system.
The power transformer field verification vehicle combines the power transformer field verification device with a special vehicle specially designed and equipped with mechanized equipment and auxiliary functions to realize the motorization, intensive and intelligentization of the power transformer field verification. All instruments and equipment for transformer calibration are centrally installed inside the vehicle, with mechanical equipment such as hydraulic lifting platform, roof electric windows, hydraulic loading and unloading machines, and hydraulic support legs to facilitate and flexibly complete the on-site operation of electric transformers. Computers and centralized control software are used to centrally control the calibration equipment to realize automatic operation of transformer calibration. According to the voltage level, it can be divided into three types: 500kV, 220kV and 110kV, 110kV and below. Can meet the corresponding voltage level CT, CVT, PT and GIS built-in transformer error detection and calibration.
