An electrical lead through connector

摘要

The subject of the invention is an electrical lead through connector (1) for connecting MV or HV conductor (7) with a load (4) placed in a tank containing a dielectric liquid or dielectric gas. An electrical lead through connector (1) comprises a plug-in bushing member (5) made of insulation material, where a series filtering choke (6) is embedded. The filtering choke (6) has a first terminal (6a) which is electrically connected with an external HV or MV line (7) and has a second terminal (6b) which is connected to a load (4) placed inside the tank (3). The lead through connector (1) is further provided with an additional bushing member (9) which is mechanically connected with the plug-in bushing member (5) through a common insulating base (8). The additional bushing member (9) is equipped with a conductor (10) located inside the bushing member (9), where the conductor (10) is connected with the second terminal (6b) of the filtering choke (6) and with an additional protective component (11) against electrical surges. The additional bushing member (9) and the plug-in bushing member (5) together with the base (8) constituting a one single element.
