Application of medium voltage isolation technology in steelmaking crane
When the slide block of the current collector of the steelmaking crane passes through the insulation isolation device of the medium-voltage sliding contact line,there is an insulating block that contacts the arc and burns out.Nowadays,a new material isolation technology is used to solve the insulation,temperature and other defects caused by the traditional 3240 epoxy board as an isolation material.This article discusses ceramics based on aluminum oxide(Al2O3)as medium-voltage isolation materials.Taking advantage of the excellent insulation,wear resistance,heat resistance,small thermal expansion coefficient,and high mechanical strength of aluminum oxide ceramics,the design Processed into medium voltage isolation blocks,Meet steelmaking crane of the medium-voltage sliding contact line the five major requirements of insulation,ultra-high temperature,wear resistance,vibration resistance and sturdiness during.
