Insulated large-capacity power transmission device

Abstract

The invention discloses an insulated large-capacity electric energy transmission device applied to a wind power generating set. The insulated large-capacity power transmission device includes several tubular busbars and support frames. The tubular busbar has a tubular conductor, an insulator arranged on the tubular conductor, and a sealing sleeve assembly arranged at both ends of the tubular conductor. The support frame has a fixed seat and a side support support seat, the fixed seat has a bearing plate and a shock absorber arranged on the bearing plate, and the bearing plate is fixedly connected with one end of the tubular busbar. The side support support seat has a movable frame and a fixed frame, the movable frame can be arranged on the corresponding tubular busbar along with the movement of the tubular busbar, and the movable frame is fixed on the fixed frame in a slidable manner. The invention achieves insulation and waterproof sealing through the sealing sleeve assembly and the insulator, and uses the moving frame and the fixed frame to support the corresponding tubular busbar. Therefore, the present invention has clear wiring, simple installation, high reliability, uniform current distribution, and shock resistance. Good, not easy to short circuit between phases, low cost.

Description

technical field [0001] The invention relates to the technical field of electric energy transmission, in particular to an insulated large-capacity electric energy transmission device applied to a wind power generating set. Background technique [0002] Wind power generators usually transmit electric energy through wind power transmission devices such as wind power cables or wind power guide rails. However, as the power of wind turbines continues to increase, the capacity of wind power transmission devices continues to increase. In some high-humidity environments, such as offshore wind power generation environments, there are strict requirements for waterproof and sealing. The existing methods of transmitting electric energy through wind energy cables or wind power guide rails can no longer meet the needs of large-capacity power transmission of wind turbines. [0003] When multiple wind energy cables are installed in parallel to realize large-capacity power transmission, it w...

The existing methods of transmitting electrical energy through wind energy cables or wind energy rails can no longer meet the needs of large-capacity energy transmission for wind turbines

[0003] When multiple wind energy cables are installed in parallel to realize large-capacity power transmission, it will cause difficulties in laying, significant increase in cost, and uneven current distribution; and when large-capacity power transmission is realized through wind power guide rails, it will cause mechanical connections. Many points, poor shock resistance, prone to short circuit between phases, unable to achieve reliable waterproof seal
