Description
- The invention relates to a high-voltage switch having a switching assembly in a metal enclosure. The invention also relates to a method for operating such a switch.
- Circuit breakers for high-voltage applications typically may comprise a switching assembly having one or more electrical switches arranged in a metal enclosure. The metal enclosure is grounded, while the switching assembly is at high-voltage potential.
- To provide a circuit breaker for even higher voltages, the size of the metal enclosure must be increased in order to keep the field strengths within acceptable limits. This is expensive and requires different circuit breaker components for different voltage ratings.
-
DE 10 2006 050 732 describes a circuit breaker using electrical switches arranged in series, with each switch located in an insulating enclosure. Impedance devices comprising grading capacitors are provided for distributing the voltage over the switches. -
EP-A-0858140 discloses a high-voltage switch according to the preamble of claim 1. - Hence, it is a general object of the invention to provide a switch design that allows to switch even very high voltages while keeping cost low.
- This object is achieved by the switch and the method of the independent claims. Various embodiments are given in the dependent claims or claim combinations.
- Accordingly, the switch comprises at least two metal enclosures, with a switching assembly arranged in each metal enclosure, wherein said switching assemblies are arranged in series and wherein said at least two metal enclosures are electrically insulated from each other. The two metal enclosures being electrically insulated from each other, and in particular being insulated from ground, allows arranging a plurality of metal-enclosed switching assemblies in series wile avoiding excessive electrical fields in any of them.
- The high-voltage switch can comprise, for example, switching assemblies with high-voltage circuit breaking and/or high-voltage disconnecting function and/or high-voltage current commutating function. In particular, the high-voltage switch can be a high-voltage disconnector, a high-voltage circuit breaker, a high-voltage current commutating device, or similar devices.
- In this design, the switching assemblies are arranged in series such that a high voltage can be switched. Each switching assembly is arranged in a metal enclosure, with the metal enclosures being electrically insulated from each other. This allows to keep the metal enclosures at different electrical potentials and therefore to reduce the electrical fields within them. Hence, smaller metal enclosures can be used.
- The design is scalable in the sense that the same metal enclosure and switching assembly can be reused for different voltage ratings. For comparatively small voltage ratings, a single enclosure and switching assembly can be used. For larger voltage ratings, two, three or even more switching assemblies can be arranged in series, with each being mounted in its metal enclosures and the metal enclosures being mutually insulated.
- In one embodiment, the switch comprises a first metal enclosure enclosing a first switching assembly as well as a second metal enclosure enclosing a second switching assembly. Further, the switch comprises a first and a second terminal. The switching assemblies are arranged in series between the terminals, such that they can interrupt a current flow between the terminals. Advantageously, the first terminal is electrically connected to the first metal enclosure and a second terminal is electrically connected to the second enclosure. Thus, the voltages between the enclosures and their switching assemblies remain comparatively small, even if the switch is switched off.
- In yet other embodiments, the switch comprises, for each switching assembly, at least one impedance device arranged in parallel to the switching assembly or are arranged between the metal enclosure and a node between the switching assemblies. The impedance devices can have matching impedances in order to evenly distribute the applied voltage over the switching assemblies and/or to compensate for a stray capacitance from the conductor to ground.
- The invention also relates to a method for operating the above switch. This method comprises the step of connecting a first one of the switching assemblies to a first high-voltage potential and a second one of the switching assemblies to a second high voltage potential in such a manner, that the switching assemblies are arranged in series between said first and said second potentials in order to interrupt the current flow between them.
