| 绝缘材料的作用 The role of insulating materials 绝缘材料又称电介质，主要用来限制电流，把电器设备中的带电部分或带不同电位的部分相互隔开，使电流按照一定的方向流动，此外还起到机械支撑、储能、散热、灭弧等作用。 Insulation material, also called dielectric, is mainly used to restrict current. It separates the electrified part of electrical equipment from other parts with different potential, so that the current flows in a certain direction. Besides, it also plays the role of mechanical support, energy storage, heat dissipation, arc extinguishing and so on. 对绝缘材料除要求有良好的电气性能外，还要求有良好的机械性能、耐热性能、使用的稳定性以及良好的工艺性能等。 In addition to good electrical properties, insulation materials also require good mechanical properties, heat resistance, stability and good process performance. 绝缘材料的好坏一定程度上决定着电器产品的质量和寿命，实际上。它在电压作用下，仍有极微小的电流通过，绝缘材料在电场内会极化，并被动地产生电场。由于绝缘材料内可能存在电场，因此绝缘材料能储藏能量。由于极化的作用，电介质在电场作用下会因消耗能量而发热。 The quality and life of the electrical products are determined to a certain extent by the quality of the insulating materials, in fact. Under the action of the voltage, it still has very small current passing through, the insulating material will polarizing in the electric field, and the electric field is produced passively. Because the electric field may exist in the insulating material, the insulating material can store the energy. Due to the effect of polarization, the dielectric will be heated by the energy consumption under the action of the electric field. |
