Installation device and method for oil level gauge of transformer capsule oil conservator

Abstract

The invention discloses an installation device and method for a transformer capsule type oil conservator. The installation device for the transformer capsule type oil conservator comprises a transformer capsule type oil conservator body, a side sealing cover, a blowing device and a vacuumizing device, wherein the transformer capsule type oil conservator body comprises an oil conservator capsule, a first oil discharge port and a second oil discharge port; the distance between the first oil discharge port and the side sealing cover is smaller than that between the second oil discharge port and the side sealing cover; a breathing port is formed in the oil conservator capsule; the blowing device is connected with the first oil discharge port; the vacuumizing device is connected with the breathing port of the oil conservator capsule. With the adoption of the technical scheme, the phenomenon that the real oil level of a transformer oil conservator cannot be displayed by an oil level gauge due to the fact that an oil level gauge connection rod is easy to break in an oil level gauge installation process in the prior art can be avoided.

Description

technical field [0001] The invention relates to the field of electrical technology, in particular to an installation device and method for an oil level gauge of a capsule type oil conservator for a transformer. Background technique [0002] The oil level gauge needs to be replaced when the transformer air-cooling system is transformed, the transformer oil conservator is overhauled, or the oil level gauge of the transformer oil conservator fails. For the currently widely used capsule oil conservator, in the current technology, when the oil level gauge is installed, the capsule of the oil conservator is naturally inflated and its shape is very irregular. When the side plate of the oil conservator is sealed, the When the connecting rod of the oil level gauge extends into the oil conservator, the inside of the oil conservator cannot be observed by the human eye, and the installation oil level can only be determined by the resistance of the connecting rod of the oil level gauge f...

Problems solved by technology

For the currently widely used capsule oil conservator, in the current technology, when the oil level gauge is installed, the capsule of the oil conservator is naturally inflated and its shape is very irregular. When the side plate of the oil conservator is sealed, the When the connecting rod of the oil level gauge extends into the oil conservator, the inside of the oil conservator cannot be observed by the human eye, and the installation oil level can only be determined by the resistance of the connecting rod of the oil level gauge felt by the installer. At the same time, in order to smoothly insert the oil level gauge connecting rod into the transformer oil conservator, it is often necessary to rotate the oil level gauge connecting rod up and down, left and right several times to find a suitable cutting angle

[0003] However, in the prior art, during the process of installing the oil level gauge, the connecting rod of the oil level gauge can easily touch the capsule of the oil conservator, thus being subjected to axial pressure and shear force in the tangential direction, causing the connecting rod of the oil level gauge to bend. As a result, the oil level gauge cannot display the real oil level of the transformer oil conservator, which leads to the occurrence of false oil level
