The insulator material plays an extremely important role in the slip ring - the isolation between the rings of the slip ring and the insulation between the main shaft of the slip ring and the ring of the conductive slip ring. Therefore, the selection of the insulating material of the slip ring must be paid attention to. .
The insulating material in the slip ring usually has the following functions:
1) Insulation isolation between the rings of the conductive slip ring.
2) Insulation isolation between the ring and the shaft of the conductive slip ring.
3) Insulation between the brushes and between the brushes and the slip ring housing
The selection of the insulator of the conductive slip ring must pay attention to the following points:
1. The mechanical strength of the insulating material of the conductive slip ring needs to meet the pressure, centrifugal force and locking force generated by the normal operation of the slip ring.
2. Processing performance of conductive slip ring insulating material: The insulating material of the slip ring must be processed in a conventional low-cost way.
3. Electrical properties of conductive slip ring insulating materials: Insulation performance is a basic requirement, and high voltage resistance must also be determined to ensure that there is no breakdown under the rated voltage.
4. Water absorption and moisture resistance of the conductive slip ring insulating material: This property ensures that the insulating material can work normally under the specified environment.
5. Temperature characteristics of slip ring insulation materials: It is necessary to meet the requirements that the relevant performance of the slip ring remains stable under the specified operating temperature.
6. Slip ring insulation material cost: The insulation material of the conductive slip ring must be easily obtained and low cost, so as not to increase the overall cost of the slip ring
At present, Ingiant Technology Co., Ltd. has undergone a large number of tests, and the insulating materials used in the slip ring can meet the following requirements at most:
1) The highest withstand voltage is 10000V
2) The maximum temperature resistance is 400 degrees
