Abstract
The invention discloses a high-voltage output terminal elbow-shaped structure of a doubly-fed wind generator. The high-voltage output terminal elbow-shaped structure comprises a terminal and a terminal accessory. The terminal is installed on a support frame, the terminal accessory is installed on the terminal, and a motor output cable is of the elbow-shaped structure through the terminal and the terminal accessory. The high-voltage output terminal elbow-shaped structure has the advantages that stress at the joint of a motor output terminal and a cable terminal is reduced, the service life of the cable at the joint of the terminal is greatly prolonged, vibration resistance of the cable is greatly improved, the joint of the motor output terminal and the cable terminal is packaged through the terminal accessory, insulating reliability of the joint is improved, and the space is greatly saved on the basis of meeting the creepage distance between wiring terminals.
Description
Technical field
The present invention relates to technical field of generators, be specifically related to a kind of double-fed wind power generator High voltage output terminal elbow type structure.
Background technology
The conventional electric generators output end wiring adopts conductive plate directly to be connected with cable connector more, the cable connection mostly is vertical hanging formula structure, raising along with the wind-driven generator single-machine capacity, in order to reduce current of electric, electric moter voltage has to promote thereupon, simultaneously also electrical machine insulation there has been higher requirement, under traditional cable connection structure, motor cable self gravitation can produce larger stress in the butted line junction, inevitably vibrate when adding the motor operation, cause wiring junction reliability to reduce, owing to be subject to the cabin space limitation, motor wiring creepage distance changes not quite than the traditional wired mode, so traditional wiring construction can not satisfy the requirement of high-voltage motor reliability service.
Summary of the invention
The object of the invention is to overcome above-mentioned not enough problem, a kind of double-fed wind power generator High voltage output terminal elbow type structure is provided.
The technical scheme that the present invention adopts for achieving the above object is: double-fed wind power generator High voltage output terminal elbow type structure, comprise terminal, terminal annex, described terminal is installed on the bracing frame, the terminal annex is installed on the described terminal, and motor output cable is elbow type structure through terminal, terminal annex.
Characteristics of the present invention are: reduced the stress of motor output end with the cable terminal junction, make terminal junction cable life-span and vibration resistance obtain great lifting, motor output end uses the encapsulation of terminal annex with the cable terminal junction, improve the junction insulating reliability, on the basis of satisfying creepage distance between binding post, saved greatly the space.
Description of drawings
Fig. 1 is front view of the present invention;
Fig. 2 is end view of the present invention;
Fig. 3 is vertical view of the present invention.
Wherein: 1, terminal 2, terminal annex 3, bracing frame.
Embodiment
As Figure 1-3, the present invention includes terminal 1, terminal annex 2, described terminal 1 is installed on the bracing frame 3, by bracing frame 3 supportings, terminal annex 2 is installed in order to encapsulation on the described terminal 1, thereby improve the junction insulating reliability, motor output cable is elbow type structure through terminal 1, terminal annex 2, saves greatly the space on the basis of satisfying creepage distance between binding post.
The above; only be the better embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or change according to technical scheme of the present invention and inventive concept thereof, all should be encompassed within protection scope of the present invention.
