Embodiment Construction

[0020] A gas insulated switchgear (GIS) device 1 typically includes, for example, a bus bar 2 for each phase; a disconnector switch 3; grounding switches 4, 7; and a circuit breaker 5, as shown in FIG. 1, but it can also Include other, further and / or different devices, as known. Such a switchgear device 1 is known from the prior art and therefore will not be explained further. The casing 11 of the GIS device 1 is filled with gas, such as SF 6 The gas, and also includes the mechanical parts of the switch, such as the contacts of the different switches of the switch device 1, the driving mechanism, etc., and the electrical conductor 10 that passes through the switch device 1. The invented optical sensor arrangement 6 is also integrated in the housing 11 for measuring current and voltage, as will be described below.

[0021] The optical sensor arrangement 6 is best shown in FIGS. 2 and 3 and will be explained below with reference to FIGS. 2 and 3. The optical sensor arrangement 6 is ...

Abstract

For electrical switchgear compact current and voltage sensor means are desired to allow a compact overall design of the switchgear. The invention discloses a very compact optical sensor arrangement for gas insulated switchgear comprising two hollow member which are arranged to form a hollow section containing optical fibres for the optical current and / or voltage sensor and which can easily be integrated into the switchgear.

Description

Technical field [0001] The present invention relates to an optical sensor arrangement, including an optical current sensor and / or an optical voltage sensor, the sensor arrangement comprising first and second hollow members, preferably circular contours, which are arranged to form a hollow part together, the sensor arrangement further comprising being arranged in The optical fiber of the current sensor in the annular groove, the groove being arranged on the boundary surface between the first hollow member and the second hollow member, and / or the optical fiber of the voltage sensor arranged in the recess of the second hollow member; The invention also relates to the use of such sensor arrangements in gas-insulated switchgear and methods of assembling and / or updating electrical switchgear. Background technique [0002] In electrical switching devices, it is necessary to measure the current flowing through the switching device and the two potentials of the switching device, such as t...
