Bus-bar unit connecting device

Abstract

The invention relates to a busway unit connecting device which is used for connecting the compact busway trough units. The device is structured into a connector assembly by two insulated clapboards 1, eight conductive connecting plates, six insulated clapboards 2, three connector heat dissipation slices, a connector press plate, a connector sleeve pipe, a disk spring, a insulated sleeve pipe and a four-phase busway trough bar. As showed in the figure, the two insulated clapboards 1, the six insulated clapboards 2 and the eight conductive connecting plates clamp the four-phase busway trough bar by groups; the two insulated clapboards 1 are arranged at the furthest outside of the connector assembly. The middle parts of the insulated clapboards 1, the conductive connecting plates, the insulated clapboards 2, the connector heat dissipation slices and the connector press plate are all provided with connecting holes; a bolt connection pair with external hexagonal angles is invaginated into the insulated sleeve and then perforates the connecting holes and is nested by the connector press plate and the connector sleeve pipe; the connector press plate is tightly pressed after the nut is fastened. A protection cover is formed by two up and bottom connector cover plates and two left and right connector side plates at the periphery of the connector assembly.

Description

Bus unit connection device technical field The invention relates to a connection device for busbar units. Background technique In the prior art, the insulation partition is made of BMC material. Due to the limitation of the material performance (with strong water absorption): after the installation of the entire busbar system in the field, it is inevitable that the insulation resistance of the entire system will decrease, which will affect the system. Safe operation brings hidden dangers. The partition between the bus phase line and the phase line adopts a single insulating partition. The insulating partition is a poor conductor of heat, which will cause heat accumulation in the bus joint, high temperature rise, and reduce the overload capacity of the bus conductor. The whole set of connection device has no limit device when connecting the busbar, the docking error between units cannot be grasped, and the bolt pre-tightening force cannot be controlled at the same time, re...

In the prior art, the insulation partition is made of BMC material. Due to the limitation of the material performance (with strong water absorption): after the installation of the entire busbar system in the field, it is inevitable that the insulation resistance of the entire system will decrease, which will affect the system. Hidden dangers in safe operation

The partition between the bus phase line and the phase line adopts a single insulating partition. The insulating partition is a poor conductor of heat, which causes heat accumulation in the bus joints, high temperature rise, and reduces the overload capacity of the bus conductors.

The whole set of connection device has no limit device when the busbar is connected, the docking error between units cannot be grasped, and the bolt pre-tightening force cannot be controlled at the same time, resulting in arbitrarily large fastening state of the connection device, which is not conducive to long-term load operation of the system
