Abstract

The invention relates to a field and especially relates to a maloperation prevention switch mechanism. The maloperation prevention switch mechanism comprises an on-column switch, an isolation switch, a conductor circuit connecting piece and a linkage interlock assembly. The linkage interlock assembly comprises a linage rod, a limiting pawl, an elastic member and a supporting frame. The supporting frame is fixed on the inner wall of a casing of the on-column switch and is opposite to the limiting pawl, the elastic member is arranged on the supporting frame, one end of the elastic member is connected with the supporting frame, and the other end of the elastic member is connected with the limiting pawl; through connecting the linkage rod between an on-column switch main shaft and an isolation switch main shaft, a linkage relation is formed between the on-column switch and the isolation switch, when the on-column switch acts, the isolation switch also acts, and the on-column switch and the isolation switch maintain consistent in terms of travel; and through arranging the limiting pawl, the elastic member and the supporting frame, a linkage interlock relation is formed between the on-column switch and the isolation switch, such that maloperation of the on-column switch and the isolation switch is prevented.

Description

technical field [0001] The invention relates to the field, in particular to an anti-misoperation switch mechanism. Background technique [0002] At present, the overhead line distribution network automation equipment mainly involves pole-mounted switches, such as pole-mounted isolating switches, pole-mounted load switches, and pole-mounted circuit breakers. These devices are air-insulated and SF6 gas-insulated. [0003] Usually, an isolating switch is arranged above the switch on the pole, and the switch on the pole and the isolating switch are connected through the conductor circuit connecting piece 14 . Specifically, such as figure 1 As shown, the switch on the column includes a box body, a vacuum bubble 4, an incoming terminal 5, an outgoing terminal 6, a first transmission mechanism 3, a main shaft of the switch on the column and a first operating handle 1; the vacuum bubble 4, The first transmission mechanism 3 and the main shaft of the on-column switch are arranged i...
