    摘要: A switchgear device may include a frame defining an interior compartment, an electrical breaker component carried within the interior compartment, and a first optical sensor carried within the interior compartment. The switchgear device may include a grounding device coupled to the electrical breaker component and being within the interior compartment. The grounding device may include an axle extending between the interior compartment and an exterior of the frame, a linkage coupled to the axle, and a grounding switch coupled to the linkage and switching between a first open state and a second closed state. The switchgear device may include a controller coupled to the electrical breaker component, the first optical sensor, and the grounding device and configured to cause the grounding switch to switch to the second closed state based upon the first optical sensor.

    摘要: A switchgear includes a circuit breaker housing defining a circuit breaker compartment. A bushing has first and second portions and extends through an opening in a rear wall of the housing so that the first portion is disposed in the circuit breaker compartment and the second portion is disposed beyond the exterior of the rear wall and external of the circuit breaker compartment. The bushing has a hollow primary contact. A current transformer is mounted on the second portion of the bushing. A fastener structure has a portion that extends through the hollow primary contact. The fastener structure couples the primary contact to a busbar in a removable manner. When the fastener structure is decoupled from the primary contact, the bushing and the at least one current transform can be accessed from the front of the housing and moved through the opening in the rear wall, for maintenance.

    摘要: A current transformer support device includes three plate-like conductors, each of which has a first connection portion at one end and a second connection portion at the other end, and which are aligned linearly side by side while being spaced apart from one another, and a current transformer case which integrally insulates and supports the three conductors between the one end and the other end. The current transformer support device is characterized in that the current transformer case has current transformer attachment portions provided at positions corresponding to at least two of the three conductors, to which ring-like current transformer coils formed so as to insert the conductors are attached, and that the current transformer case and the current transformer coils attached to the current transformer attachment portions are formed into one unit with a hardening insulating material.

    摘要: A compact electrical bushing has a separate insulating end cap removably attached to the shaft of the bushing at an end used for mounting a current transformer. The removably attached insulating end cap has a large outer diameter that increases the linear surface distance of the bushing. The outer diameter may be determined in a predefined manner based on the desired length of the shaft, and vice versa, with a larger outer diameter corresponding to a shorter shaft. The increased linear surface distance allows the bushing to meet minimum tracking distance with a shorter shaft relative to existing bushings. The shorter shaft reduces the footprint of switchgear and other electrical isolation equipment to which the bushing may be connected. The insulating end cap may be removed from the bushing as needed to allow the current transformer to be slid onto the bushing without having to pass over the end cap.

    摘要: A polyphase, compressed-gas-insulated cable entry module includes an encapsulation. A plurality of phase conductors, which are electrically insulated from one another by compressed-gas insulation, are disposed in the interior of the encapsulation. The phase conductors are each electrically conductively contacted by cable connection bushes. The cable connection bushes are inserted into separate tubular connection pieces of the encapsulation. The tubular connection pieces lead into a common feeder housing of the encapsulation.
