中温盐炉采用可控硅调压快速启动后,一台45kW的盐炉每年可节电4万kWh左右,确是一种典型的快速启动方法。但是,由于启动电压、电流均较大,一般在3～8min就可击穿炉底固体盐,电阻降低,电流迅速增大。因而在高压击穿进行完毕后,改用侧埋电极继续低压启动时,盐炉底部电流较大,而且变化过猛,极易使控制柜里与闸刀相连的管式保险丝熔断,更换 Thermostat in the temperature furnace with SCR quick start, a 45kW salt furnace can save about 40,000 kWh per year, is indeed a typical quick start method. However, due to the start-up voltage and current are large, usually 3 ~ 8min can penetrate the solid bottom salt, resistance decreases, the current rapidly increases. Therefore, after the high-voltage breakdown is completed, the switch to use low-voltage side burned electrode start, the bottom of the salt furnace current is large, and the change is too fast, easy to make the control cabinet with the blade connected to the fuse fuse fuse, replace
