Three column type high voltage alternating current isolating switch electric conduction structure

The utility model discloses a three column type high voltage alternating current isolating switch electric conduction structure comprising static contact heads and electric conduction switch knife, wherein the electric conduction switch knife is rotatably arranged in such a way that the middle point of the electric conduction switch knife is used as a circle center; the electric conduction switch knife comprises moving contact heads that are respectively arranged on two ends; each static contact head comprises an insulating plate, a wire connecting terminal, a support rack and contact sheets matched with one moving contact head; the wire connecting terminal which is fixedly connected with a shaft sleeve is fixedly arranged on the insulating plate, the shaft sleeve is connected with the support rack in a rotating manner in the radial direction, one end of the support rack is provided with the contact sheets while the other end is electrically connected with the wire connecting terminal through flexible connection, and the static contact heads that are respectively matched with the moving contact heads are symmetrically arranged on the rotation path of the moving contact heads. The electric conduction switch knife is arranged rotatably, through-flow is realized through contact between the moving contact heads arranged on the two ends of the electric conduction switch knife and the contact sheets arranged in the static contact heads, through-flow capability is effectively improved, simple assembly is realized, product cost is lowered, contact flexibility and contact sensitivity are ensured, structure simplicity and structure reliability are realized, and required through-flow capability can be achieved.
