Abstract
Abstract Enclosed switching apparatus has a tank, a circuit breaker, a pair of contact pedestals provided on both sides of the circuit breaker, and a disconnecting switch. The tank is provided with a lead-out portion extending in a direction perpendicular to the axis of the breaker and disposed adjacent to one of the contact pedestal. The disconnecting switch is at least partially disposed in the lead-out portion, with the axis of the disconnecting switch being coincident with the axis of the lead-out portion. An operating device is provided for operation of the movable contact of the disconnecting switch. A drive bar member couples the movable contact to the operating device, extends through the tank along a line of extension of the axis of the disconnecting switch and includes a conductor portion electrically connected to the movable contact. A slide contact is mounted on the above-mentioned one of the contact pedestals to slidably receive the conductor portion of the drive bar member.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
354 words
An enclosed switching apparatus of the type having: a tank including a main cylindrical portion filled with an insulating gas and provided, at a first end thereof, with a removable cover, a circuit breaker provided in and concentrically with said main cylindrical portion of said tank and including a housing, a stationary contact provided at a first end of said circuit breaker adjacent to said first end of said tank, and a movable contact provided at a second end of said circuit breaker, first and second contact pedestals respectively provided at said first and second ends of said circuit breaker, and a disconnecting switch including a stationary contact and a movable contact engageable with said stationary contact, said tank being provided with a lead-out portion extending perpendicularly to the axis of said main cylindrical portion, with the axis of said lead-out portion intersecting the axis of said main cylindrical portion, and disposed adjacent to one of said contact pedestals, and said disconnecting switch being at least partially disposed in said lead-out portion, with the axis of said disconnecting switch being substantially coincident with the axis of said lead-out portion, said enclosed switching apparatus further comprising: a disconnecting switch operating device mounted to said main cylindrical portion for operating said movable contact of said disconnecting switch, a drive bar member mechanically coupling said movable contact to said operating device, said drive bar member extending through said one of said contact pedestals and crossing the axis of said main cylindrical portion of said tank, substantially along a line of extension of the axis of said disconnecting switch, and including a conductor portion electrically connected to said movable contact of said disconnecting switch, a slide contact mounted on said one of said contact pedestals to slidably receive said conductor portion of said drive bar member, a circuit breaker operating device provided at a second end of said tank opposite to said first end, and including an insulating member movable for operating said movable contact of said circuit breaker, said movable contact of said circuit breaker being detachable from said insulating member of said circuit breaker operating device.
