摘要： An easily removable high voltage ground stud insulating system allows ready access to the ground stud bolt having one end directly attached to a switchgear terminal bus, with the other end adapted to receive a temporary ground connector. A two-part insulative enclosure consisting of a first thermoplastic insulative cylinder is arranged over that part of the ground stud that is adapted for connection with the ground connector while a second insulative cylinder is arranged over the other end. The insulating properties of the thermoplastic material virtually eliminate arcing between the ground stud and the surrounding atmosphere when the switchgear is energized with high voltage. The insulating system is adapted for connection with the ground stud by means of a pair of threaded washers that serve to attach the insulative cylinders on both sides of the ground connector.

摘要： Power receiving/distributing equipment is composed of a switchgear incorporated for each major electric path section, wherein, when arc fault occurs on an electric path to which a circuit breaker is connected, a high-speed closing device closes to detour arc current so as to flow to a ground conductor, thereby eliminating arc at a fault electric path portion. The high-speed closing device is connected to one pole or both poles of a breaking portion of the circuit breaker, and is incorporated into an insulating support member on a corresponding pole electric path so as to be able to be drawn as a whole.
