一种调压开关触头装置的优化设计

为解决农村等偏远地区电压偏低问题，配合国家农村电网改造工程，先后开发了多种电力智能调压器。开发过程中遇到某型号调压开关使用的传统触头部件存在接触不良、拉弧等问题，严重影响了调压器的使用性能。在对产品优化分析的基础上，设计了一种闭合自紧式触头装置，通过动触头和静触头充分可靠的接触，保证了调压开关运行的稳定性，增加了通流能力。装机试验证明，该装置性能可靠、运行稳定，并且结构紧凑，制造成本低。

Optimal Design for Contact Device of A Voltage Regulating Switch

In order to solve the problem of lower voltage in rural areas and other remote areas, a variety of intelligent voltage regulators have been developed in cooperation with the national rural power grid reconstruction project. In the process of development, the traditional contact parts used in a certain type of voltage regulating switch have some problems, such as poor contact and arcing, which seriously affects the performance of voltage regulator. On the basis of product optimization analysis, a closed self-tightening contact device is designed. Through the full and reliable contact between moving contact and static contact, the stability of voltage regulating switch is ensured and the flow capacity is increased. The installation test shows that the device has a reliable performance and stable operation with compact structure and low manufacturing cost.
