High-voltage distribution box switch opening knife
The HR3 Series Fuse Knife Switch (hereinafter referred to as "switch") is suitable for industrial and commercial power distribution systems with AC 50 Hz, rated voltage of 380 V and conventional thermal current up to 1,000 A, and is used for the overload and short-circuit. Primary Plus is a pre-engineered solution set that provides utilities with a means to reduce the time and labor associated with substation construction and expansion, while at the same time utilizing technologies and methodologies familiar to existing resources. A higher relative humidity is allowed at low temperatures, such as up to 90% at 20°C. For example: HS1Knife switch used for high voltage circuits earthing, downstream of the traction converters. The blades are operated directly by the maintenance operator using an insulation stick in this configuration.
