Internal oil circuit of a large oil-filled slip ring for power transmission

Abstract

The invention discloses an internal oil circuit of a large-scale oil-filled type power transmission slip ring. An oil pipe flange and an exhaust flange are arranged on the rotating cover of the slip ring. The oil pipe is installed on the oil pipe flange and extends through the support seat to the The bottom of the ring; a circle of windows is set on the top seat of the outer ring, and the base of the outer ring is closed. When the slip ring is in use, the oil is circulated, and the external oil pump sends the oil from the exhaust flange to the inner cavity of the slip ring, and the oil passes through the outer ring. The window on the top seat enters the position of the ring between the stator and the rotor of the slip ring to take away the wear debris, and finally the oil carries the wear debris and flows out of the slip ring from the oil pipe at the bottom of the slip ring. Through the design of the internal structure, the present invention can ensure that the wear debris between the inner and outer outlet rings is taken away during the oil circulation.

Description

technical field [0001] The invention relates to a power slip ring technology, in particular to an internal oil circuit of a large oil-filled power transmission slip ring. Background technique [0002] The existing electric slip rings generally have low voltage power for passing current, small size, and low service life requirements, so the internal structure is relatively simple, and air insulation is mostly used. During the operation of this kind of slip ring, the wear debris generated by the contact and the position of the ring road will fall on the bottom of the slip ring under the action of gravity, which generally does not affect the use of the slip ring. [0003] Chinese patent CN 206322976 U (authorization announcement date 2017.7.11) discloses a power slip ring device for a single point mooring system, the slip ring is applied to an offshore single point mooring platform, the transmission voltage and power are large, and the service life is required. The traditional...

[0003] Chinese patent CN 206322976 U (authorized announcement date 2017.7.11) discloses an electric slip ring device for a single point mooring system. The slip ring is applied to an offshore single point mooring platform. High, the traditional electric slip ring cannot meet the requirements, so the slip ring adopts an internal oil-filled design

The content of this patent is of creative significance, but it does not specifically design the oil circuit circulation inside the slip ring. It only proposes the idea of ​​using internal oil storage and oil pumping for large-scale power transmission slip rings. Therefore, this patent supplements CN 206322976 U , the oil passage inside the slip ring is specially designed to realize the rationality of the oil circulation of the slip ring during the first oil filling, maintenance and oil discharge and use
