HRGW1-35KV new fuse HRGW1 wind type drop-out fuse fuse type isolating switch for AC 50Hz, 380V, rated current up to 1000A of the distribution system as a short-circuit protection and cable, wire overload protection available. Under normal circumstances, do not frequent manual for making and breaking of normal load current and overload current, short-circuit conditions, the fuse breaking current. This product complies with IEC60947-3 GB14048.3 standards. Second, the series fuse type isolating switch 1 normal operating conditions the ambient air temperature is not higher than + 40 ℃, not lower than -5 ℃. 2 installation site altitude does not exceed 2000m. 3 Humidity: maximum temperature is + 40 ℃, the relative humidity of air no more than 50% at a lower temperature allows a higher relative humidity, for example, up to 90% at 20 ℃. Right as the condensing temperature to produce the occasional special measures should be taken. Pollution degree Ambience is 3. 5 switch should be installed in the absence of a significant shake, shock and vibration, and there is no rain and snow, while the installation site should be non-explosive medium, the medium does not enough to corrode metal and damage the insulation of gas and dust. Third, the structural characteristics of fuse switch disconnectors fuse switch disconnectors (hereinafter referred to as switch) is a combination of electrical fuses and knife switches, fuses and basic properties knife switch, in case of normal power supply circuit, the turn-on and switch off the power to serve as the knife. When the line or electrical equipment overload or short circuit, the fuse melt blown, time to cut off the fault current. Front maintenance switch operation, the central fuse for maintenance and replacement of doors, installation of the main distribution panel for the BDL. Before operating installation maintenance switch main distribution panel for the BSL. Overhaul of the front side of the operation switch can be made closed power distribution box. Rated current 1000A and below the knife switch with a safety shield and with interrupter. Interrupter phenolic cloth panels and steel parts riveting punch made.
