Description

Technical Field

[0001] This utility model relates to the field of high-voltage motor technology, and in particular to a star-connected wiring device for a high-voltage motor slip ring. Background Technology

[0002] In industrial production, high-voltage motors need to carry high voltage and large current. As the core component for current transmission, the slip ring has extremely high requirements for the safety, stability and efficiency of the wiring structure. Traditional slip ring wiring often faces problems such as insufficient insulation performance, poor structural stability and large energy loss. Moreover, it is difficult to achieve accurate and balanced transmission in three-phase current distribution, which not only affects the operating efficiency and service life of the motor, but may also cause production losses due to failure shutdown.

[0003] The wiring technology of the slip ring of the high-voltage motor has revealed many shortcomings that urgently need to be addressed in practical applications. From the perspective of insulation performance, the insulation design between various conductive components in the traditional wiring method is flawed, and the quality of the insulation materials is inconsistent, making it difficult to withstand the high voltage impact during the operation of the high-voltage motor. This leads to frequent phase-to-phase short circuits and short circuits to ground. For example, some wiring structures that use ordinary insulation materials and have unreasonable insulation spacing are prone to aging and damage under long-term high voltage, causing the originally isolated conductive parts to come into direct contact, resulting in short circuits and seriously threatening the safe operation of the motor.
