Description
Technical field
The utility model relates to high-voltage motor technical field, specifically a kind of H level 6.6kV level high-voltage motor stator coil insulation system.
Background technology
The insulating material major part that motor uses is organic material, the thermal endurance of the insulation system that it forms and useful life are far below wire and iron core, it is the weak link of motor, motor insulation structure directly affects and determines permission temperature rise and the useful life of motor, affect the quality and cost of motor, at some special occasions, require very high to motor useful life, ambient temperature, common F level high voltage insulation structure can not meet requirement, domestic H class F insulation structure is mold pressing or middle glue insulation system mostly, there is the defect that insulation thickness is thicker; The reliability and the life-span that are adopting the thermal endurance few glue insulating base improving insulation system to can further improve motor.The trend of modern electrical machine insulating Design selects grade higher than the insulation system of electrical machine insulation grade, and focus is born by insulation margin, uses sufficient temperature limit during design of electrical motor.Such as B level motor adopts F class F insulation system, and the copper loss of B level motor is by 95 DEG C of calculating (copper loss of F level motor is by 115 DEG C of calculating), and electric efficiency also can be higher.Therefore the overall economics index of motor can be improved.The key improving the thermal endurance of insulation system is performance after insulating resin, mica tape and combination thereof.
Utility model content
The purpose of this utility model is the deficiency existed to solve prior art, provides a kind of high-voltage motor stator coil insulation system.
The technical solution of the utility model is as follows:
A kind of high-voltage motor stator coil insulation system, include straightway insulated part and bending section insulated part, it is characterized in that: described straightway insulated part includes employing two mica tapes and wraps up six layers of first insulating barrier formed by mixing half lap outward at coil body straightway, the first described insulating barrier is outer is wrapped with the first low-resistance belt by half-stack package; Described bending section insulated part includes employing two mica tapes and wraps up five layers of second insulating barrier formed by mixing half lap outward at coil body bending section, and the second described insulating barrier is outer is wrapped with the second low-resistance belt by half-stack package; First and second described low-resistance belt is outer is wrapped with high stop band by half-stack package, and described high stop band is outer is wrapped with alkali-free glass silk ribbon by half-stack package.
Described high-voltage motor stator coil insulation system, is characterized in that: two described mica tapes adopt 5452-1,5452-1D vacuum pressure mica paper tape respectively.
The beneficial effects of the utility model:
The utility model excellent electrical property, minimum disruptive voltage 92.00kV, breakdown minimum field intensity 61.33MV/m, normality dielectric loss (0.875%), hot dielectric loss (13.235%, 180 DEG C) low, normal ageing temperature index reaches 181, can ensure the operational reliability of high-voltage asynchronous motor preferably.
Accompanying drawing explanation
