The inner SF of described gas tank
6Insulating gas air pressure is to wait atmospheric pressure.
The beneficial effects of the utility model are: because the utility model is provided with the described isolation knife assembly of described arc control device assembly and the asynchronous interlock of series connection with it, the isolation switch of being controlled on the described isolation knife assembly by described single spring electromagnetic operating mechanism closes a floodgate prior to arc control device, the back is in the arc control device separating brake, and all live parts are enclosed in and atmospheric SF such as are full of
6In the stainless air chamber of gas, adopt vacuum extinction, SF
6Gas-insulated, so break performance is good, reliability is high, electric arc does not expose in cut-offfing, and can not pollute and damage the electric elements in the cabinet.Because the electric elements in the switch cubicle open apart from little, arc voltage is low, arc energy is little, contact burning is few, so the number of times that it can cut-off rated current is higher than the switch of other type far away, the life-span is long, need not overhaul.Gas tank and underframe assembling are that independent module can combination in any be expanded, and have unified assembling interface, make things convenient for the upgrading expansion between composite module, just produce the deadline of having improved contract option with tissue.Therefore the utility model is rational in infrastructure, is that a kind of volume is little, simple in structure, stable performance, the switch cubicle that the life-span is long.
