Description
Technical field
This utility model belongs to technical field of wind power generator, is specifically related to a kind of sliding ring brush carrier of wind-driven generator.
Background technology
The sliding ring brush frame being currently used for wind-driven generator has the disadvantages that the existing insulator for 1.5MW slip ring
Material is BMC, and its glass fibre is shorter, and mechanical performance is poor, and intensity can not meet greater power slip ring and use；Carbon brush pressure
The pressure change instability of spring, during work or rapid drawdown or rising, the non-linear ratio with the active length of stage clip, so,
Carbon brush can not stably conduct electricity, and loose contact is the most easily burnt slip ring surface；Single earth protective device is the most firm, once loses efficacy,
Insulation bearing is caused damage；Three copper posts are inadequate for the safety of high-power slip ring, and conductive capability is weak.
Utility model content
For solving the problems referred to above, the purpose of this utility model is to provide a kind of sliding ring brush carrier of wind-driven generator, and insulator is adopted
With SMC material, excellent insulating property, good mechanical property, constant force spring is increased to limit φ 24.3mm by original φ 23.5mm,
Pressure is more stable；Double ground connection slip ring protected mode is used to replace original single earth protective device, the more reliable big electricity of protection wind-force
The insulation bearing that machine is expensive；Nine copper post connecting modes of the uniqueness of this utility model slip ring, considerably increase copper post and slip ring
Contact area.
For realizing above-mentioned technical purpose, reaching above-mentioned technique effect, this utility model is achieved through the following technical solutions:
A kind of sliding ring brush carrier of wind-driven generator, including slip ring, main brush carrier, brush bracket device and the copper being arranged on described slip ring
Binding post, described slip ring is staggered installation of by insulator and main slip ring and constitutes on slip ring beam barrel, and described main brush carrier passes through support bar
It is arranged on described brush bracket device and contacts with described main slip ring, described main brush carrier is provided with constant force spring, also include installing
At the insulated end cover of described slip ring upper end, described insulator is SMC material compression molding.
Further, described constant force spring is a diameter of more than 23.5mm, less than or equal to 24.3mm, heat treatment employing vacuum
Quenching, pressure constant voltage performance inconsistency is 16N ± 5%.
Further, described copper binding post is nine, every described copper binding post is provided with wiring and joins pad.
Further, described sliding ring brush frame is provided with double earth protective device.
Further, the encoder seat being arranged on described slip ring lower end is also included.
The beneficial effects of the utility model are:
1, insulator of the present utility model uses SMC material, excellent insulating property, good mechanical property, and hardness is high, in reality
In utilization, its mechanical performance and insulating properties exceed BMC；
2, this utility model constant force spring is increased to limit φ 24.3mm by original φ 23.5mm, and heat treatment uses vacuum
Quenching, and special test platform screening qualified products, come into operation, and its pressure constant voltage performance is carried by original fluctuation 16N ± 10
Raising 16N ± 5%, pressure is more stable；
3, this utility model uses double ground connection slip ring protected mode to replace original single earth protective device, more reliable protection
The insulation bearing that the big motor of wind-force is expensive；
4, nine copper post connecting modes of the uniqueness of this utility model slip ring, considerably increase the contact surface of copper post and slip ring
Long-pending, promote 2.27 times than old product.
