Xi'an Power Capacitor Co., Ltd. breaks through UHV technical problems

Not long ago, Xi'an Power Capacitor Co., Ltd. and State Grid Corporation signed a supply contract for a million-volt capacitor-type voltage transformer (CVT), which will provide six hundred for China's first UHV AC pilot demonstration project in Henan Nanyang Station. Ten thousand volts CVT. The current development work has made gratifying progress.
The company has made several technological breakthroughs in the development of a million-volt CVT.
The first is mechanical strength and seismic capacity. They have taken a number of measures in structural design and cooperated with Xi'an Jiaotong University to calculate the mechanical strength and seismic capacity. The prototype developed passed the earthquake resistance of 0.25g horizontal acceleration at Tongji University. test.
Secondly, the pressure equalization technology reduces the distribution of electric field distribution inside and outside the product and improves the uniformity of the external electric field distribution through reasonable structural design inside and outside the product. In the design and development process, the advanced mature technology of parallel capacitors was successfully applied to the capacitive voltage transformer, which significantly reduced the partial discharge of the product.
Through careful design, it has broken through a number of key technologies and achieved technical requirements such as high precision, large output capacity, high mechanical strength, low dielectric loss, low temperature rise, long life, good sealing performance and large creepage distance.
