Abstract
An enhanced phase-to-phase insulation structure of an increased safety motor comprises a stator iron core, stator coils and coil lead wires. Single-sided imine film reinforced less rubber powder mica tapes are arranged between the adjacent coil lead wires. According to the enhanced phase-to-phase insulation structure of the increased safety motor, the phase-to-phase corona resistance of stator windings is enhanced, corona onset voltages are increased, and the enhanced phase-to-phase insulation structure of the increased safety motor is suitable for the fields of motors.
Description
Technical field
The present invention relates to technical field of motors, relate in particular to a kind of INCREASEDSAFETY motor and strengthen phase insulation structure.
Background technology
After GB 3836-2010 promulgates, the insulation system of INCREASEDSAFETY motor need to be tested in the mixture shown in table one, applies the sine wave of 1.5 times of rated line voltages (effective value), lasts 3min.The voltage maximum climbing should be 0.5kV/s.Voltage should be applied between a phase and ground, other phase ground connection.The duration of test generation of should not exploding.
Insulation system should be able to bear 3 times to 10 potential pulses of peak value phase-to-ground voltage, and voltage rising time is at 0.2us-0.5us, and the amplitude time over half at peak value is at least 20us.Pulse should put on relative phase and relatively between.The duration of test generation of not exploding.
Summary of the invention
The purpose of this invention is to provide and a kind ofly can strengthen the anti-corona ability that stator winding is alternate, improve a kind of INCREASEDSAFETY motor of discharge inception voltage and strengthen phase insulation structure.
The present invention is achieved in that a kind of INCREASEDSAFETY motor reinforcement phase insulation structure, comprises stator core, stator coil, coil lead wire, it is characterized in that: be provided with single face imines film reinforcement dry mica paper tape between adjacent coil lead wire.
The present invention has strengthened the alternate anti-corona ability of stator winding, has improved discharge inception voltage.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
In figure 1, stator core, 2, stator coil, 3, single face imines film reinforcement dry mica paper tape, 4, the coil lead wire.
Embodiment
Below in conjunction with accompanying drawing, the present invention is further illustrated:
With reference to accompanying drawing, a kind of INCREASEDSAFETY motor is strengthened phase insulation structure, comprises stator core 1, stator coil 2, coil lead wire 4, it is characterized in that: be provided with single face imines film reinforcement dry mica paper tape 3 between adjacent coil lead wire 4.During concrete enforcement, stator core, after carefully connecting the wire, embeds 0.14mm * 25mm single face imines film reinforcement dry mica paper tape between adjacent two-phase, then uses 0.1mm * 25mm glass fiber to interweave the band colligation on coil, whole dipping lacquer.The present invention is tested in the mixture shown in table one, applies the sine wave of 1.5 times of rated line voltages (effective value), lasts 3min.The voltage maximum climbing should be 0.5kV/s.Voltage is applied between a phase and ground, other phase ground connection.The duration of test generation of should not exploding.
