Problems solved by technology

[0013] Furthermore, the fixing system disclosed in document EP 2 685 268 A1 cannot be mounted on downwards pointing windows due to the stud system (B) which is hardly compatible with such an orientation
[0014] It should be noted that the second disadvantage of such a fixing system is that it is not suitable for outdoor installation
In fact, a sensor held in place by such a fixing system does not have any protection against inclement weather, and a UHF sensor held by such a system may be damaged in the event of rain or high humidity

Embodiment Construction

[0084] figure 1 The fixing system 10 of the invention is shown mounted on a window 6 and its support 5 of a high voltage substation 1 , said fixing system 10 enabling the fixing of a UHF sensor 140 on said window 6 .

[0085] Such a fixing system 10 is especially designed to be fitted on a gas-insulated high-voltage substation, for example a substation using insulating gas insulation, better known as a gas-insulated substation (GIS).

[0086] as above and figure 2 As shown, such a substation 1 comprises at least one rectangular window 6 fastened to the rest of the substation 1 by means of supports 5 . exist figure 1 and figure 2 In , the support is a circular flange screwed on the opening of the substation 1 . The window 6 is mounted on the support 6 while protruding therefrom.

[0087] Naturally, although the window 6 and the support 5 or flange securing the window to the rest of the substation are respectively rectangular and circular, the invention is fully compatibl...

Abstract

The invention relates to a system (10) for holding an ultra-high-frequency (UHF) sensor (140) on a view port (6) of a high-voltage electrical station (1). The holding system (10) comprises at least one attachment element to be attached to the electrical station (1), facing the support (5); a part for holding the UHF sensor (140) designed to at least partially house the UHF sensor (140), the holding part also being designed to be placed in an opening (119) of the attaching element; and at least one first locking body (130) designed to allow the manual locking of the holding part (120) in position in the opening (119) of the attachment element (110). The invention also relates to an assembly of UHF sensors, an electrical station (1), and a method for attaching a UHF sensor (140) to a view port (6) of an electrical station (1).

Description

technical field [0001] The present invention relates to the field of installation of ultra high frequency (UHF) sensors on high voltage substations, and more particularly to the fastening of such UHF sensors to said high voltage substations. Background technique [0002] Monitoring and maintenance of high-voltage substations, especially gas-insulated substations, requires the use of UHF sensors, also known as UHF antennas. In particular, such a UHF sensor can detect, inter alia, the presence, if any, of partial discharges which are characteristic of insulation defects in substation housings. [0003] Although such UHF sensors may be permanently installed in substation housings, it is often more economical to install them on windows of such substations during maintenance operations. This is especially true for older substations that have no equipment other than windows for mounting such UHF sensors. Mounting such a sensor on a window thus makes it possible to inspect and / or...
