GW1-35 Outdoor high voltage separation relationship outdoor installation general purpose isolating switch
1 General
GW1-35 Outdoor high voltage separation relationship outdoor
installation general purpose isolating switch. Forthree-phase
alternating current 50Hz. Rated voltage 12KV and below the power
system. The circuit is switched on when there is a voltage without
a negative voltage.. The product is in line with the GB1985 "AC
high voltage isolation switch and grounding switch". DL486 order
"technical conditions for AC high voltage isolating switch,The
national standard DL/T593 "high voltage isolation switch equipment
common order technical conditions" and the power industry standard.
2 Using environmental conditions.
2.1 altitude 3000M.
2.2 ambient temperature is -25 degrees C to +40.
2.3 wind pressure is not more than 700Pa.
2.4 ice thickness is not more than 1mm.
2.5 earthquake intensity is not more than 8 degrees.
2.6 the installation site should have no regular violent vibration
and flammable. Effect of explosive material and chemical corrosion.

4 Structure principle
4.1GW1 - 35 switch outline and installation dimensions are shown in
Figure 2.
GW1 - 35 for single phase structure. Each phase consists of a
chassis, the main knife (ground knife), movable contact head,
static contact head, shaft, rod insulators. Three-phase through a
connecting pipe is connected, the operation shaft with rod
insulators to drive the main knife switch, touch knife with trough
outline form, increased mechanical strength and heat dissipation
area.
4.2 GW1-35D -switch is a kind of switch on the GW1 - 35 to add a
ground knife.
Equipped with CS6-2 operating mechanism after the, can achieve the
main knife switch, knife cannot contract; knife switch, the surgeon
can not closing the anti error interlocking requirements.
4.3 GW1 - 35 switch with CS6-2 mechanism (see Figure 1).
