Arm axle coordinates.
The driving connecting lever that the high-voltage board includes connecting lever axis is driven to rotate with formula breaker drive mechanism drives connecting lever
It is arranged on the connecting lever axis of monopole pole in an intermediate position along in monopole column orientation.
The cabinet of the utility model matches somebody with somebody formula breaker：Cabinet matches somebody with somebody formula breaker monopole pole
Column, monopole pole are equipped with Crankarm box, are equipped with connecting lever axis in Crankarm box, the both ends of connecting lever axis are stretched out Crankarm box and are respectively equipped with
With the connection structure for being sequentially connected with the connecting lever axis of adjacent monopoles pole.
The connection structure is to be arranged on the internal spline or external splines of connecting lever shaft end.
The beneficial effects of the utility model are：Each connecting lever axis is connected with the connection structure on connecting lever axis；It is driven during use
Dynamic any connecting lever axis is rotated, it can be achieved that the synchronization action of each connecting lever axis.Compared with the prior art, when a certain phase on breaker or
When two-phase breaks down, it need to will only be removed with the driving member in the corresponding Crankarm box of failure, maintenance workload is smaller, and
And the gas chamber of each monopole pole is spaced from each other, when maintenance, only needs to discharge gas indoor with the corresponding gas of failure, reduces
Maintenance cost.
