中频断路器内置电量附件的设计

Design of Electric Accessory Putting Inside Intermediate Frequency Breaker

介绍了一种中频断路器内置的电量附件的软硬件设计方案。该电量附件用于监测接入断路器的电压电流有效值、有功功率、无功功率、功率因数、频率、相序等参数,各种参数通过电量附件上的通信接口传输给其他设备。该附件成本低,便于产业化,具有较高的工业价值,可用于高温环境。

A software and hardware design method of electric accessory putting inside intermediate frequency breaker were introduced. The electric accessory could supervise the effective value of voltage, current and active power, reactive power, power factor, frequency, phase sequence of breaker. The parameters could be transported to other devices through the communication port of the electric accessory. The accessory had low cost and high industrial value, easy to be industrialized, and could be used in high temperature environment.
