Abstract

The invention relates to a density relay protection cover, and the protection cover comprises a cover body, a fixing sealing device and an observation device. The size of the cover body is matched with the size of a density relay installed inside, and the cover body can be closely attached to the density relay, and also can save the installation space of the density relay protection cover. The fixing sealing device is connected with the cover body, and is used for fixing the cover body and the density relay, and sealing the cover body. The observation device is disposed at a side part of the cover body, and is used for observing the operation conditions of the density relay. The device provided by the invention can solve a problem that a protection cover of a sulfur hexafluoride density relay in the conventional scheme is not reliable in packaging.

Description

technical field [0001] The present application relates to the technical field of substation maintenance, in particular to a protective cover for a density relay. Background technique [0002] At present, sulfur hexafluoride gas is usually used instead of insulating oil in various high-voltage electrical equipment as an arc extinguishing and insulating medium in high-voltage electrical equipment. Sulfur hexafluoride gas density density relay is a measuring instrument used to monitor the density of sulfur hexafluoride gas in high-voltage electrical equipment. Its accuracy plays an extremely important role in the safe operation of high-voltage electrical equipment. However, during the outdoor operation of the sulfur hexafluoride density relay, due to wind, sun, and rain, the dial and aviation plug are prone to water ingress and moisture, electrical contact insulation reduction, and even misoperation. [0003] For the protection of the sulfur hexafluoride density relay, the res...
