Encapsulation module for gas-insulated HV switchgear

摘要

The encapsulation module has a three-phase combined breaker and earthing switch supported by two insulator discs (27), with a switch element cooperating with an earthing contact secured to the encapsulation housing. The breaker separation point (15) is provided by one arm of a T-shaped phase conductor section. The opposite side of the insulator discs are provided with a field control terminal (25) and enclosed by an encapsulation cover (26). Preferably, each switch consists of a cylindrical contact which is moveable in the longitudinal direction.
