Abstract

An insulating fluid monitoring block includes an insulating fluid channel. The insulating fluid channel is connected through a branch channel to a cutout. A sensor element is at least partly disposed in the cutout. The sensor element serves for monitoring an insulating fluid. A mounting method for an insulating fluid monitoring block is also provided.

First claim

The invention claimed is:

1 . An insulating fluid monitoring block, comprising:
a supporting body, said supporting body having an insulating fluid channel with an inlet opening and an outlet opening, and said supporting body having a cutout formed therein; a branch channel connecting said cutout to said insulating fluid channel; and a sensor element at least partially projecting into said cutout formed in said supporting body, said sensor element at least partly creating a fluid-tight closure of said cutout.

2 . The insulating fluid monitoring block according to claim 1 , which further comprises a cover spanning and closing said cutout.

3 . The insulating fluid monitoring block according to claim 2 , wherein said cover includes a data interface.

4 . The insulating fluid monitoring block according to claim 1 , wherein said sensor element includes an active part and a passive part, said active part is exposed to said insulating fluid channel and said passive part is configured to process information from said active part.

5 . The insulating fluid monitoring block according to claim 1 , which further comprises an inlet fitting having a valve body controlling said inlet opening.

6 . The insulating fluid monitoring block according to claim 1 , wherein said supporting body has mutually opposite ends, said insulating fluid channel has a linear course and an outlet opening, and said inlet opening and said outlet opening are each disposed at a respective one of said mutually opposite ends.

7 . The insulating fluid monitoring block according to claim 6 , which further comprises:
an inlet fitting closing said inlet opening and an outlet fitting closing said outlet opening; said inlet fitting and said outlet fitting each having fastening points distributed around said respective inlet opening and outlet opening; and said fastening points being disposed offset relative to one another in an alignment direction.

8 . The insulating fluid monitoring block according to claim 1 , wherein said supporting body has a substantially cuboid shape or cubic shape.

9 . The insulating fluid monitoring block according to claim 1 , wherein said inlet opening includes an actuating element for a valve body for controlling access to said insulating fluid channel.

10 . The insulating fluid monitoring block according to claim 1 , wherein said insulating fluid channel is configured to be coupled to a gas space of an encapsulation housing of an electrical energy transmission device.

11 . A method for mounting an insulating fluid monitoring block, the method comprising:
providing a supporting body having an insulating fluid channel with an inlet opening and an outlet opening; connecting an inlet fitting to a fluid container wall; using the inlet fitting to close the inlet opening of the insulating fluid channel; and using an outlet fitting to close the outlet opening of the insulating fluid channel prior to closing the inlet opening with the inlet fitting.

12 . The method for mounting an insulating fluid monitoring block according to claim 11 , which further comprises using an outlet fitting to close an outlet opening of the insulating fluid channel, using the inlet fitting to close the inlet opening, and carrying out the closing of the inlet opening and the outlet opening in a common working step.

13 . The method for mounting an insulating fluid monitoring block according to claim 12 , which further comprises using an actuating element to actuate a valve body along with closing the inlet opening with the inlet fitting.
