Description

Technical Field

[0001] The utility model relates to the technical field of electric power engineering, and more specifically to a lead frame used for a collector circuit of a wind power plant. Background Art

[0002] The wind farm collection circuit is a system that collects the output power of multiple wind turbines into a collection system through cables, and then transmits the power to the substation or power grid. The collection circuit includes all cables, connectors, lead frames and other equipment between the wind turbines and the substation.

[0003] The lead frame of the wind farm collector circuit is a structure used to support and fix the collector cable. It is usually a frame made of metal material.

[0004] The existing lead frame still has the following problems: the lead frame of the existing wind farm collector circuit is mostly fixed with a metal tie or screw in combination with a fixing sleeve when fixing the collector cable. This method is cumbersome when fixing or removing the cable, and requires professional tools for removal, which undoubtedly reduces the installation efficiency of the staff. In addition, after the cable is fixed, the wire body of the existing lead frame is relatively messy, and it is difficult for personnel to find the designated cable during maintenance, which undoubtedly brings great trouble to the use;

[0005] In addition, existing lead frames are often installed on the power collection system to facilitate the connection of power generation cables of multiple wind turbines. However, when a fire or failure occurs at the cable connection end or the cable, the warning is poor and it is difficult for personnel to discover and extinguish the fire in time, which leads to the further spread of the fire, which undoubtedly poses a great hidden danger to the safety of use.

[0006] In view of this, we propose a lead frame for a collector circuit of a wind farm. Utility Model Content
