Oil conservator for sleeve and processing technology of oil conservator

Abstract

The invention discloses an oil conservator for a sleeve and a processing technology of the oil conservator. The oil conservator comprises an oil conservator main body, wherein an oil conservator coverplate is mounted at one end of the oil conservator main body, a rear end sealing plate is mounted at the other end of the oil conservator main body, mounting holes are respectively formed in the middle of the rear end sealing plate and the middle of the oil conservator cover plate, a copper pipe for electric conduction is mounted in the mounting hole, the front end part of the copper pipe extendsout of the end of the oil conservator cover plate, a conductive head matched with the copper pipe is mounted on the oil conservator cover plate, the rear end of the copper pipe and the oil conservator main body are pressed and sealed through a rear end sealing plate, a spring pressing mechanism assisting in pressing and sealing is mounted on the copper pipe located in the oil conservator main body, an oil meter is mounted at the upper end of the oil conservator main body, and a connecting rod floating ball extending into the oil conservator main body is mounted at the lower end of the oil meter. According to the invention, a cylindrical transverse and straight placement mode is adopted, detection, oiling and scale discharging can be better facilitated, the rear end sealing plate is pressed and sealed through the counter-acting force of the spring, the sealing performance of the rear end sealing plate is guaranteed, the stability is good, and damage is not likely to happen.

Description

Technical field: [0001] The invention relates to the field of transformers in the electrical industry, and mainly relates to an oil conservator for bushings and a processing technology thereof. Background technique: [0002] The oil conservator is one of the important parts on the bushing. It mainly plays the role of oil storage and can ensure that the oil conservator is full of oil. At the same time, because the contact surface between the oil conservator and the air is reduced, the water and dust absorbed in the air will Oil and grease are deposited on the bottom and can be drained off periodically. There is an oil gauge on the side of the oil conservator, which can detect the change of oil level. Due to the current development of transformer technology, the update of this type of bushing technology forces all components including quality and service life to be enhanced, especially for such a large oil conservator. Before installation, first check whether the bushing is d...

Problems solved by technology

Due to the current development of transformer technology, the update of this type of bushing technology forces all components including quality and service life to be enhanced, especially for such a large oil conservator. Before installation, first check whether the bushing is damaged and whether the fasteners are Clean the dust and dirt on the surface of the casing. The inner cavity of the conductive pipe of the cable structure must be clean. However, the existing oil conservator has a simple structure. When the oil level is too high, it is easy to cause excessive pressure inside the casing and damage Poor stability can easily lead to oil leakage from the casing, the sealing performance cannot meet the requirements, and the oil level is too low, it is impossible to observe the change of the oil level, so the structure of the oil conservator needs to be improved
