Embodiment Construction

[0017] The specific implementation manner of the present invention will be further described in conjunction with the technical scheme and accompanying drawings.

[0018] Such as figure 1 As shown, a wind power conductive slip ring electrical contact wear tester has a cuboid sheet metal structure in appearance, and is mainly surrounded by a case cover 7, a front panel 16, a hatch 10 and a bottom plate 19 with four legs 14. The wear test chamber 22, spindle drive control, loading contact force and friction force measurement, wear test chamber temperature control and other functional units are set inside, and the contact pressure, wear speed and number of turns of the friction pair can be set, and the charged accelerated friction and wear test can be carried out. It has the functions of data collection, display and transmission.

[0019] Among them, the start switch 2, the speed control knob 1, the indicator light 3, the counter meter 4, the temperature control meter 5 and the f...

Abstract

The invention provides a wind power conductive slip ring electric contact abrasion tester structure. The tester structure can be used for conducting a ring and brush wire accelerated charged abrasion test and conducting sliding friction abrasion and dynamic contact resistance state detection. The tester structure has a cuboid sheet metal structure, and is mainly formed by a case cover, a front panel, a cabin door and a baseplate; an abrasion test cabin, a main shaft driving control unit, a loaded contact force and friction force measuring unit and an abrasion test cabin temperature control unit are arranged in the tester structure; the friction pair contact pressure, the abrasion rotating speed and the number of turns can be set, the data acquisition display and transmission functions are achieved, the use is convenient, the operation is simple, and the tester structure can be applied to abrasion test occasions of various conductive slip rings.

Description

technical field [0001] The invention relates to a wear test platform, in particular to a structure of a wind power conductive slip ring electric contact wear test machine. Background technique [0002] The wind power pitch slip ring is mainly composed of a stator and a rotor. There can be multiple conductive rings and insulators on the rotor that are responsible for power and signal transmission. The outer cylindrical surface of each conductive ring is processed with ring grooves, and the surface is treated with multi-layer precious metal plating. The brushes installed on the stator are made of gold alloy wire, and the elastic pressure of the brushes is in sliding contact with the ring grooves of each conductive ring. Transmission of power and control signals, as a key device, requires safety, reliability, stability, maintenance-free and long life. However, problems such as friction and wear in the electrical contact state between the conductive ring and the brush wire and ...
