Abstract
The utility model discloses an insulation structure of a generator stator winding, which comprises a lead-part insulation structure, an end-part insulation structure and a linear-part insulation structure. The lead-part insulation structure comprises a polyimide film adhesive tape wrapped on the outside of the naked wire of a lead, a Tung-Ma glass-mica tape wrapped on the outside of the polyimide film adhesive tape, and a polyester tape wrapped on the outside of the Tung-Ma glass-mica tape. The end-part insulation structure comprises a Tung-Ma glass-mica tape wrapped on the outside of the naked wire of an insulation part, a high-resistance anti-corona tape wrapped on the outside of the Tung-Ma glass-mica tape, and a polyester tape wrapped on the outside of the high-resistance anti-corona tape. The linear-part insulation structure comprises a Tung-Ma glass-mica tape wrapped on the outside of the naked wire of a linear part, and a low-resistance anti-corona tape wrapped on the outside of the Tung-Ma glass-mica tape. Due to the adoption of the insulation structure, each part of the stator winding is insulated targetedly. Meanwhile, the insulation structure is low in cost and good in insulation effect, and can effectively reduce the failure probability of the generator.
Description
Technical field
The utility model relates to generator, especially the insulation system of aerogenerator stator coiling.
Background technology
Wind-driven generator is installed in hundreds of rice high-altitude, can be subject to the effect of lightning overvoltage, so when design wind driven generator insulating structure, consider that coil should have the ability of anti-corona.In addition, when wind-driven generator moves, also to be subject to the effect of mechanical force, electromagnetic force and vibrations, make generator insulating be in the effect of alternate stress, accelerate the aging of electrical machine insulation.So when design wind driven generator insulating structure, take into full account the comprehensive function impact that coil insulation is subject to these factors.The heart that all motor coil is become motor in the field of business, the coil insulation insulation then is the heart of motor heart, through statistics for many years, the fault that motor occurs is because motor stator insulated damage is caused, so the design of motor stator insulated structure is very important more than 50%.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of insulation system of generator unit stator coiling, and good insulation preformance can effectively reduce the fault that generator causes because of the stator winding insulation.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of insulation system of generator unit stator coiling, described generator unit stator coiling is comprised of lead portion, end sections and straight line portion, and described insulation system comprises the structure of becoming attached to of lead portion, the insulation system of end sections and the insulation system of straight line portion; The insulation system of described lead portion comprises and is wrapped in the outer polyimide film adhesive tape of lead portion bare wire, is wrapped in the outer paulownia horse glass dust mica tape of polyimide film adhesive tape and is wrapped in the outer polyester belt of paulownia horse glass dust mica tape; The insulation system of described end sections comprises and is wrapped in the outer paulownia horse glass dust mica tape of insulated part bare wire, is wrapped in the outer high resistance corona-prevention belt of paulownia horse glass dust mica tape and is wrapped in the outer polyester belt of high resistance corona-prevention belt; The insulation system of described straight line portion comprises the paulownia horse glass dust mica tape low resistance corona-prevention belt outer with being wrapped in paulownia horse glass dust mica tape that is wrapped in outside the straight line portion bare wire.
The beneficial effect that the utility model compared with prior art brings is:
Every part of stator winding is carried out the specific aim insulation, and cost is low, and insulation effect is good, can effectively reduce the probability that generator breaks down.
