Abstract
The utility model discloses a direct drive type wind electric power generation unloading resistance, which comprises a frame body formed by a face plate, side plates and a bottom plate. The two ends of a resistance tube are connected with the side plates at two sides. The direct drive type wind electric power generation unloading resistance is characterized in that a silicone rubber gasket is arranged between the resistance tube and the side plates, a screw rod penetrates through the resistance tube, an insulating porcelain ring is arranged between the screw rod and the internal wall of the resistance tube, the screw rod is connected with a screw cap after penetrating through the side plate, an insulator is also arranged between the screw cap and the side plate. The face plate is provided with heat dissipation meshes. The utility model has the advantages of simple structure, improvement of safety performance due to three times of insulation, and better heat dissipation effect due to the meshes arranged on the face plate.
Description
Technical field
This practical device relates to a kind of direct-driving type wind power generation off-load resistance.
Background technology
When breaking down, electrical network consumes the unnecessary energy of DC side by discharging circuit, effectively reduce the dc voltage fluctuation, improve the useful life of dc bus capacitor, fault does not exert an influence substantially to the operation of wind energy conversion system and generator when making short circuit such as electric network electric voltage drop, thereby improves the subnormal voltage operation ability of direct-driving type wind power generation system.The off-load resistance of prior art.Original off-load resistance adopts primary insulation, if insulation processing is bad, has very big potential safety hazard.
The utility model content
The purpose of this utility model provides a kind of more reliable, the direct-driving type wind power generation off-load resistance of safety.
To achieve these goals, technology division of the present utility model is: a kind of direct-driving type wind power generation off-load resistance, comprise the framework that panel, side plate and base plate constitute, the two ends of resistance tube are connected with the both sides side plate, it is characterized in that being provided with silicone rubber gasket between resistance tube and the side plate, be installed with screw rod in the resistance tube, be provided with the insulation porcelain ring between screw rod and the resistance tube inwall, screw rod is connected with nut after passing side plate, also is provided with insulator between nut and the side plate.Have the heat radiation mesh on the panel.
Advantage of the present utility model is simple in structure, adopts three minor insulation, makes security performance improve, and panel is offered mesh, and radiating effect is better.Therefore when breaking down, electrical network can reliably effectively finish off-load, thereby effectively reduce the dc voltage fluctuation, improve the useful life of dc bus capacitor, fault does not exert an influence substantially to the operation of wind energy conversion system and generator when making short circuit such as electric network electric voltage drop, thereby improves the subnormal voltage operation ability of direct-driving type wind power generation system.
