High-pressure standing submersible motor winding wire assembly

Abstract

The invention relates to a high-pressure standing submersible motor winding wire assembly, comprising a winding group. The winding group comprises a sealed heat-standing soft tube sleeve pre-fabricated and wound in the motor and a soft metal conductor packaged in the sealed heat-standing soft tube sleeve. As a further improvement in the above technical scheme, an insulation layer is sleeved on the sealed heat-standing soft tube sleeve, and a protection sleeve layer is sleeved on the insulation layer. The two ends of the sealed heat-standing soft tube sleeve are provided with conductive joints in connection with the soft metal conductor. According to the invention, the assembly is reasonably designed with a compact structure and can be used conveniently.

Description

technical field [0001] The invention relates to a high-voltage resistant submersible motor winding wire assembly. Background technique [0002] At present, the winding wires of submersible motors mostly adopt the structure of polyethylene insulated nylon sheath. In order to ensure the insulation performance under high voltage, the insulation thickness is 0.5 mm when applied to 500 volts, and the insulation thickness is 1 mm when applied to 1000 volts. , as the voltage increases, the thickness of the insulating layer must increase, which greatly occupies the precious space of the stator slot of the motor, makes the volume of the high-voltage submersible motor larger, and reduces the efficiency of the submersible motor. [0003] The current winding is made of copper wire, which is solid and heavy, and is not suitable for high-end industries. The resistivity at the corner is high, resulting in power loss, poor heat dissipation, high heat generation, and difficult to observe tem...
