Description

Medium-voltage cable clamping block assembly for wind power

Technical Field

The utility model relates to a medium voltage cable clamp block subassembly for wind-powered electricity generation for the medium voltage cable is fixed in the vertical section tower section of thick bamboo of wind generating set.

Background

At present, in the competitive price and flat price era of the fan market, fan cost reduction becomes the primary target of a whole plant, and the key of fan cost reduction is to reduce the cross section and the number of power cables. In order to reduce the construction cost of a wind power project and improve the power generation performance of a fan, a medium-voltage system can be adopted by a wind generating set. The medium-voltage system can reduce the cable consumption, save the construction cost and improve the voltage grade.

At present, the application of medium-voltage systems is less, the fixing method of the medium-voltage cable is immature, and particularly, the existing method for binding the power cable by the binding belt is not suitable for the medium-voltage cable. Therefore, a fixing assembly for the medium-voltage cable in the tower of the vertical section of the wind generating set is urgently needed to be applied to a medium-voltage system.

Disclosure of Invention

In order to overcome the not enough of prior art, the utility model provides a medium voltage cable clamp block group spare for wind-powered electricity generation has solved the too thick problem that is difficult to fix of medium voltage cable.

The utility model provides a technical scheme that its technical problem adopted is:

the utility model provides a wind-powered electricity generation is with middling pressure cable clamp block subassembly, includes clamp splice, lower clamp splice, clamp splice mount and cable clamp splice crossbeam fixation clamp, last clamp splice with form the cavity that is used for pressing from both sides tight middling pressure cable down after the clamp splice docks, the clamp splice is installed down on the clamp splice mount, set up cable clamp splice crossbeam fixation clamp on the clamp splice mount.

Furthermore, bolt holes are formed in the upper clamping block and the lower clamping block, and bolts penetrate through the bolt holes in the upper clamping block and the bolt holes in the lower clamping block to be fixed on the clamping block fixing frame. This is the preferred solution, but can also be fixed by other means.

Preferably, the upper end and the lower end of the cable clamping block beam fixing clamp are fixedly connected with the clamping block fixing frame through bolts, and a middle clamping station of the cable clamping block beam fixing clamp is used for being sleeved with a cable bridge. This is preferred and the clamp block holder may be fixed to the cable tray by other means.

The beneficial effects of the utility model are that: the medium-voltage cable clamping block assembly can fix a medium-voltage cable in a vertical section of tower barrel, so that the problem that the medium-voltage cable is too thick and difficult to fix is solved; the medium-voltage cable clamping block assembly can ensure the reliability of the wind generating set field medium-voltage cable fixing process, can reduce the medium-voltage cable damage risk, is simple and convenient to operate, and saves manpower.
