• Product Overview
HD knife switch and knife-shaped transfer switch(hereinafter referred to as the switch) is applicablefor the complete set of distribution unit with the AC frequency of 50Hz, rated current up to 380V andthe rated current up to 3000A, to turn on and off the AC and DC circuit in an infrequent manner orserve as isolation switch Central handle switch is mainly used in the power station to serve as anisolation switch. lt will not cut off the live circuit.
Side front lever operating mechanism switches forfront operation,front switchgear maintenance.operating mechanism cabinet mounted on both sidesCentralfrontlever operating mechanism switch is mainly used for switchgear cabinet offrontamaintenance from behind, and the operating mechanism is installed dead aheadSwitch with a side handle is mainly used in power box.Switch with an interrupter switch can cut off proper current load, while other seriesof knife switches can only serve as isolation switch.This product conforms to GB14048.3 IEC6047-3 standard.
• Modeland Significance
• NormalWorking Conditions
□The ambient airtemperature is not higher than +40 Cand notlower than-5C □The altitude of the installation siteshall not exceed 2000m
□Humidity:when the maximum temperature is+40 C,the relative humidity of the air does not exceed50%.At a lower temperature,a higher relative humidity can be allowed,such as 90%at 20 C.Corresponding measures should betaken for the occasional condensation due to temperature changes
□The pollution level ofthe surrounding environment is level
□The switch shall be insta.lled in a place without significant shaking,shock vibration and rain and snow invasion.At the same time,the installation siteshall be free of explosive dangerous media, and the media shall be free of gas and dust that are sufficient to corrode metal
