Abstract

A high-voltage power switch, preferably with a dead tank design, contains: a switching unit that has a switching device and an actuation element that is axially movable in relation to a longitudinal axis of the switching device to actuate the switching device and a closing resistor unit that has a closing resistor arrangement and an adjusting element that is axially movable in relation to a longitudinal axis of this closing resistor arrangement to actuate the closing resistor arrangement. The actuation element is coupled to the adjusting element in order to move the latter. Accordingly, the longitudinal axis of the switching unit and the longitudinal axis of the closing resistor unit are spaced apart, and the actuation and adjusting elements are coupled by a coupling device of the high-voltage power switch.

First claim

The invention claimed is:

1. A high-voltage circuit breaker, comprising:
a switching unit having a switching device and an operating element being axially movable in relation to a longitudinal axis of said switching device, for operating said switching device, said switching unit having a housing with an interior;
a coupling device having a coupling mechanism with at least one linkage;
a closing resistor unit having a closing resistor configuration and an actuating element, being axially movable in relation to a longitudinal axis of said closing resistor configuration, for operating said closing resistor configuration, wherein said operating element is coupled to said actuating element by said at least one linkage to move said actuating element, wherein the longitudinal axis of said switching unit and the longitudinal axis of said closing resistor unit are spaced apart from one another, wherein said closing resistor unit further having a housing with an interior, said at least one linkage of said coupling device being disposed outside of all housings including outside said housing of said switching unit and outside said housing of said closing resistor unit and therefore being exposed to a surrounding environment;
at least one cross connection, said interior of said housing of said switching unit connected to said interior of said housing of said closing resistor unit by means of said at least one cross connection; and
the high-voltage circuit breaker having a dead tank design.

2. The high-voltage circuit breaker according to claim 1 , wherein the longitudinal axes of said switching device and of said closing resistor configuration have an axis offset.

3. The high-voltage circuit breaker according to claim 2 , wherein the longitudinal axes of said switching device and of said closing resistor configuration are disposed in parallel.

4. The high-voltage circuit breaker according to claim 1 , further comprising a frame or some other base which carries said switching unit and said closing resistor unit.

5. The high-voltage circuit breaker according to claim 1 , wherein said switching unit and said closing resistor unit are disposed next to one another.

6. The high-voltage circuit breaker according to claim 1 , wherein said switching unit is disposed above said closing resistor unit.

7. The high-voltage circuit breaker according to claim 1 , wherein said closing resistor unit is disposed above said switching unit.

8. The high-voltage circuit breaker according to claim 1 , wherein said coupling mechanism further has at least one lever and/or at least one shaft.
