2.Model Specification
Independent Innovation Indoor Hv Disconnector-Yfgn35-40.5/T630

3.Applicable environment
1. Altitude is not more than 1000m 
2. Ambient air temperature comes to -25ºC~+40ºC
3. Relative humidity: daily average value is not more than 95%;
4. Ambient air shall not clearly polluted by air dust, corrosive or flammable gas, vapor, or salt spray, etc
5. In the secondary system, inductive electromagnetic amplitude value shall not be more than 1.6kv


4. Structure and Principle
1. Basic structure mainly composed of frame, Isolation Switch. Isolation knife, vacuum arc extinguishing chamber are fixed on frame with isolator. Operation mode is side operation. Operation mechanism drives main shaft of switch, main shaft rotates and drives vacuum arc extinguishing chamber or isolation knife to act with crutch through Insulation operation bar, realizing the switch knife opening and closing operation.
See Fig.1 and Fig.2 for outline and installation dimension of combined electric appliance 
2. Work principle
Switching on and off operation for isolation knife .
