绝缘材料的作用 The function 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。 Is also called the dielectric insulating material, is mainly used to limit the current, the electric part of the electrical equipment or parts with different potential separated from each other, make the current according to certain direction, in addition to mechanical support, energy storage and heat dissipation, arcing, 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 the requirements of insulating material has excellent electrical properties, also requires a good mechanical properties, heat resistance, the use of stability and good process performance, etc. 　　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 The quality and longevity of electrical products are determined in part by the quality and longevity of electrical products. It still has a very small current through the voltage, and the insulation is polarized in the electric field and generates an electric field passively. It may be stored in an insulating material 　　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 In an electric field, insulation materials can store energy. Because of the polarization, the dielectric can be used by the electric field to consume energy
