【摘要】 耐电压实验通常用于评估电器和电气的绝缘性能,实验方法是给绝缘体施加超过它通常使用的正常电压而不至于击穿。耐电压意图是模仿真实的意外事件并在短时间内检验电器和电气的安全性能。实施耐电压的设备叫耐电压测试仪。 随着加入WTO,中国统一了众多行业的产品许可证认证制度,为此而实施强制性的CCC安全认证。CCC认证则更多地强调产品的安全性能,因此市场针对测试电器安全性能之一的耐电压测试仪需求迅速增加。根据不同被试产品的国家标准要求以及各种被试产品生产过程中的现实情况,对耐电压测试仪各种型号的需求也是多样的。而耐电压测试仪本身技术指标要求也必须符合国家相应标准规定。 本文主要介绍耐电压测试仪系列的设计。根据各种类型的耐电压测试仪控制电路部分具有很多相似性特点,力争生产不做重大调整的情况下,尽量将设计扩展为各种使用类型的耐电压设备,以快速和低成本地满足市场需求。因此对高压与被试物质之间关系的足够了解,是统一设计方案的重要工作。再通过对通用型小容量耐电压设备的研制和生产,充分检验产品主要部分质量的稳定性和设计的合理性。 在扩展产品中,本文介绍补充设计的群测耐电压测试仪和针对电机的自动复位/启动耐电压测试仪。群测增加快速判断被击穿产品的功能,自动复位/启动重点在控制动作时间。因此,从而印证了在不更改主设计的基础上,增加辅助设计,实现产品的扩充。更多还原

【Abstract】 Dielectric withstand testing is used to evaluate wiring and electric insulation. It is way of testing that the insulation be tested at a much greater voltage than normal to ensure that the insulation is not marginal. The intent of the dielectric test is to stress the insulation for a short period of time and check that it does not fail. The device names withstands voltage tester.With China joining WTO, many methods for checking license to product is unified to CCC. The CCC is compellent authentication to prove ability of manufacture for the product. It emphasize that it is important for safety-performance to the product. So market need rapidly more and more the devices for dielectric withstand testing. It is important one of safety testing. According to standards of a variety of being test products and idiographic conditions of manufacture, market needs many types and models of withstands voltage tester. But it also is compelled by corresponding standards.The article introduce mainly design of catena about withstands voltage tester. According to semblable trait of control circuit in many types and models for withstands voltage tester, the design should ensure manufacture of a variety of testers is not magnitude changes in order to the variety be provided rapidly and in low cost. It is important for unifying project of the design that we must concern with characteristic between high voltage and being test material. First, design and manufacture of universal and low power tester can testify adequately rationality and stability of the project for the catena.According to application for radical trait of the control circuit of universal and low power withstands tester, the article continues to introduce two design projects for batch withstands tester and automatic return/startup one for electromotor. Expansion designs never change the radical project of the primal design. Batch withstands tester only add function of distinguish from unqualified products. Automatic return/startup tester adds function of control time of return/startup. It is proved that the primal design reasonable.更多还原
