Abstract
The utility model discloses a sliding ring brush yoke system, including sliding ring, carbon brush and brush yoke, the carbon brush sets up in the brush box to can be in the brush box longitudinal movement, the upper end of carbon brush is equipped with alarm contact, be equipped with alarm device on the brush box, alarm device includes main tributary strut, micro -gap switch, switch shaft and is used for touching single limb support of micro -gap switch, the switch shaft passes the main tributary strut, be equipped with the switch case who holds micro -gap switch on the main tributary strut, single limb support is fixed on the switch shaft and can be wound the axle center rotation of switch shaft, be equipped with the torsional spring that enables single limb support and reset on the switch shaft, main tributary strut and switch case are made by insulating material. The problem and service environment's insulating problem of the sliding ring brush yoke system fundamentally switch shaft of having solved traditional alarm device and the easy jamming of main tributary strut wearing and tearing, simple structure is convenient for produce, low cost is applicable to the wind power generation field and extensively promotes.
Description
Technical field
The utility model is related to a kind of sliding ring brush frame system.
Background technology
With continually developing for wind power plant, the high speed development of wind-powered electricity generation industry, collector ring product be widely used in plateau,
The various harsh and unforgiving environments such as Gobi desert, ocean, damp and hot, as ambient humidity is big, rarefaction of air is exhausted for the sealing of sliding ring brush frame system
Edge requires to be also raised to new height.Traditional alarm unit be iron supporting construction, be susceptible to strike sparks flashover, without
Method meets the requirement of operation environment, therefore a kind of new sliding ring brush carrier of wind-driven generator is badly in need of being developed.
Utility model content
Proposition of the utility model for problem above, and a kind of sliding ring brush frame system of research and design.The utility model is adopted
Technological means is as follows：
A kind of sliding ring brush frame system, including slip ring, carbon brush and brush holder, the carbon brush is arranged in brush box, and can be in brush box
Inside vertically move, the upper end of the carbon brush is provided with Alarm contactor, and the brush box is provided with warning device, and the warning device includes
Main backstop, microswitch, switch shaft and the single bow arm support for touching microswitch, the switch shaft pass through main support
Frame, the main backstop are provided with the switch housing for accommodating microswitch, and single bow arm support is fixed on switch shaft and energy
Rotate around the axle center of switch shaft, the switch shaft is provided with the torsion spring that single bow arm support can be made to reset, the main backstop and open
Shell is made up of insulating materials outside the Pass.
Further, the switch shaft is fixed in main backstop by sealed bearings, and the sealed bearings include rolling
Bearing and the bearing seal cover for being arranged on rolling bearing lateral surface.
Further, the main backstop and switch housing are made up of material more than H levels of the class of insulation.
Further, the material of the main backstop and switch housing is polyphenylene sulfide.
Compared with the prior art, sliding ring brush frame system described in the utility model fundamentally solves traditional alert device
Switch shaft and main backstop wear and tear easy clamping stagnation problem and use environment Insulation Problems, prevent sparking flashover existing
As.In addition, the utility model simple structure, is easy to production, and cost is very cheap, it is adaptable to which wind power generation field is extensively pushed away
Extensively.

Specific embodiment
As shown in Figures 1 to 7, a kind of sliding ring brush frame system, including slip ring 1, carbon brush 2 and brush holder 3, the carbon brush 2 is arranged
In brush box 4, and can vertically move in brush box 4, the upper end of the carbon brush 2 is provided with Alarm contactor 5, and the brush box 4 is provided with
Warning device 6, the warning device 6 include main backstop 7, microswitch 8, switch shaft 9, and for touching microswitch 8
Single bow arm support 10, the switch shaft 9 pass through main backstop 7, the main backstop 7 to be provided with the switch for accommodating microswitch 8
Shell 11, single bow arm support 10 are fixed on switch shaft 9 and can rotate around the axle center of switch shaft 9, set on the switch shaft 9
There are the torsion 15 that single bow arm support 10 can be made to reset, the main backstop 7 and switch housing 11 to be made up of insulating materials.The present embodiment
In, the main backstop 7 and switch housing 11 are made up of material more than H levels of the class of insulation, can be at 200 DEG C to 240 DEG C
Long-Time Service, with outstanding wearability, good stability of the dimension, high mechanical strength, stiff super, it is hot and humid under remain to keep
Good insulating properties, itself have anti-flammability, therefore preferably polyphenylene sulfide (PPS) material.Using insulating supporting structure, will be dynamic
Power electricity is isolated entirely from control signal, meets the requirement of particular surroundings application.
The switch shaft 9 is fixed in main backstop 7 by sealed bearings 12, and the sealed bearings 12 include rolling bearing
13 and be arranged on the bearing seal cover 14 of 13 lateral surface of rolling bearing, solve tradition exploitation rotating shaft and it is main support abrasion, easily
The problem of clamping stagnation.
Embodiment described above is only that the preferred embodiment of the present invention is described, not the model to the present invention
Enclose and be defined, on the premise of without departing from design spirit of the present invention, technical side of the those of ordinary skill in the art to the present invention
Various modifications and improvement that case is made, all should fall in the protection domain of claims of the present invention determination.
