Transmission and distribution projects. Petroleum. chemical, metallurgy and mining. And exported to Europe. Africa, Vietnam, Iran, Mongolia and other countries and regions. Willing to work with customers at home and abroad to work together to create brilliant. Briefly zinc oxide arrester arrester with good protection performance. Use of zinc oxide non-linear volt-ampere characteristics, so that when the normal working voltage of the current flowing through the arrester is very small (microamps or milliamps); resistance sharply decreased when the over-voltage effects, vent let the voltage of the energy , to achieve the protective effect. This arrester and the arrester difference is that it does not discharge gap, the use of the nonlinear characteristics of the zinc oxide to play the role of the bleeder and breaking. National standards, the system power supply terminal voltage should be slightly higher than the nominal voltage of the system (or the rated voltage) Un K times, that K = Um / Un (Um is the highest system voltage). The insulation of electrical equipment should be in the long-term operation under Un. 220kV and below the system's K 1.15,330 kV and above system K = 1.1. Early arrester designed to comply with the above principles. The zinc oxide arrester before SiC arrester. Extinction voltage of 10kV and below SiC arrester is set at the maximum operating voltage of 1.1 times; 35kVSiC arrester extinction voltage is equal to the maximum system voltage; 80% of the maximum system voltage interrupter voltage of 110kV and above SiC arrester. Multiples, respectively, over the corresponding 110% arrester 100% surge arresters and 80% of the arrester.
