Abstract
Abstract Fast-acting disconnect switches are arranged in the branches of a completely insulated high-voltage switching system. The bus bar of the system is fed by a power circuit breaker. The switches disconnect the branch circuits during the currentless interval caused by the operation of the power circuit breaker. The disconnect switches each have first and second connecting conductors at right angles to each other and are arranged in a configuration wherein the first connecting conductors face the power circuit breaker and together form the straight-line bus bar and the other connecting conductors for the branch lines facing away from the power circuit breaker are arranged in a single plane.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
152 words
In a completely insulated high-voltage switching system having a bus-bar fed through a power circuit breaker, a plurality of disconnect switches for connecting a corresponding plurality of branch lines to the bus-bar and for disconnecting the same during a currentless interval caused by a short opening of the power circuit breaker, each of the disconnect switches having first and second connecting conductors, the second connecting conductor being connected to a corresponding one of the branch lines; the improvement comprising the arrangement wherein the first connecting conductor of each of the disconnect switches is directed toward the breaker and is disposed to define a right angle with respect to the second conductor thereof, the first connecting conductors of the disconnect switches being arranged in a straight line to conjointly define the bus-bar, said second connecting conductors being in one plane and the power circuit breaker forming a common plane with the disconnect switches.
Claim 2
Dependent Claim
152 words
In a completely insulated high-voltage switching system having a bus-bar fed through a power circuit breaker, a plurality of disconnect switches for connecting a corresponding plurality of branch lines to the bus-bar and for disconnecting the same during a currentless interval caused by a short opening of the power circuit breaker, each of the disconnect switches having first and second connecting conductors, the second connecting conductor being connected to a corresponding one of the branch lines; the improvement comprising the arrangement wherein the first connecting conductor of each of the disconnect switches is directed toward the breaker and is disposed to define a right angle with respect to the second conductor thereof, the first connecting conductors of the disconnect switches being arranged in a straight line to conjointly define the bus-bar, said second connecting conductors being in one plane and the power circuit breaker forming a common plane with the disconnect switches.
Claim 3
Dependent Claim
15 words
The completely insulated high-voltage switching system of claim 1, said disconnect switches having gas-filled housings.
Claim 4
Dependent Claim
30 words
The completely insulated high-voltage switching system as claimed in claim 1, in which a voltage transformer connected with the bus bar lies in the same plane as the disconect switches.
Claim 5
Dependent Claim
32 words
