Bus coupler device and solid-sealed polar pole, and bus coupler device-solid-sealed polar pole system

Abstract

The invention relates to a bus coupler device and a solid-sealed polar pole, and a bus coupler device-solid-sealed polar pole system. The bus coupler device comprises a bus coupler device plug terminal. The solid-sealed polar pole comprises a solid-sealed polar pole plug terminal. The bus coupler device plug terminal is a plug column and the solid-sealed polar pole plug terminal is a plug hole which is cooperated with the plug column in a plug mode, or the bus coupler device plug terminal is a plug hole and the solid-sealed polar pole plug terminal is a plug column which is cooperated with the plug hole of the bus coupler device in the plug mode. The bus coupler device-solid-sealed polar pole system comprises a contact finger used for making the bus coupler device plug terminal and the solid-sealed polar pole plug terminal be conductively connected. When a traditional bus coupler device and the solid-sealed polar pole are connected in a bolt connection mode, disadvantages that an overlapping area is insufficient; materials are wasted; installation efficiency is low; pull crack is easy to achieve; there is no displacement compensation and so on are possessed. In the invention, the above disadvantages are effectively overcome. Installation is convenient, safe and reliable. An installation precision requirement is low and miniaturization is achieved.

Description

technical field [0001] The invention relates to a bus coupler, a solid-sealed pole and a bus coupler-solid-sealed pole system. Background technique [0002] The bus coupler is a device used for short-circuit control in the power system and is the link between the two busbars. The embedded pole is to embed the conductive parts related to the vacuum interrupter and the circuit breaker into the easily curable solid insulating material such as epoxy resin or thermoplastic material to form a pole, so that the entire circuit breaker pole becomes an integral part . [0003] At present, the connection between the bus coupler and the solid-sealed pole used in the power system is usually bolted, mainly including metal sheet lapping and two outlets butt joints. The bolted connection is a fixed connection, and the bus coupler is connected by bolts. The terminal of the device and the terminal of the solid-sealed pole are fixed on the two surfaces that are attached to each other. This c...
