Abstract

The invention discloses a sealing ring aging test device, and relates to the technical field of sealing ring tests, aiming at solving the problem that the service life of a sealing ring can not be accurately measured under gas pressure in the prior art. The sealing ring aging test device comprises at least one flange plate; the upper surface and/or lower surface of the flange plate are/is respectively provided with a mounting groove used for installing a sealing ring along the circumferential direction; flange covers are respectively connected with the upper part and the lower part of each flange plate, so that a closed cavity is formed in the flange plate; inflatable holes communicated with cavities are formed in the flange covers; the inflatable holes are connected with an air charging device.

Description

technical field [0001] The invention relates to the technical field of sealing ring testing, in particular to a sealing ring aging test device. Background technique [0002] In high-voltage power transmission technology, sulfur hexafluoride (ie SF 6 ) as an insulation and arc extinguishing medium to isolate high-voltage electrical appliances from the outside world. Sulfur hexafluoride under a certain pressure is filled in the gas-insulated closed combination appliance, which is clamped by flanges, and a sealing ring structure is set between the flanges to seal it. Due to the long-term use of the sealing ring, the seal will fail due to aging, resulting in the leakage of sulfur hexafluoride. [0003] The test device for measuring the aging of sealing rings in the prior art includes two flanges, an installation groove is opened on one of the flanges, the sealing ring is installed in the installation groove, and then the two flanges are clamped, and finally the Put it into th...
