应用于保护电能传输系统的全电阻继电器

The Impedance Relay Used in the Hall Effect of a Semiconductor

介绍了一种新型的应用于保护电能传输系统的全电阻继电器:基于非线性平衡原理,在正常状态下,在输出之前加上一个半导体霍尔元件和一个整流器.实验结果证明,新型全电阻继电器灵敏度高,测量范围广,并具备尺寸小,价格低等优点.

A new type of definite impedance relay applicable to the protection of power transmission systems is described.Its operation is based upon a differential balance,under normal conditions,between the output from Hall effect in a semiconductor element and a rectifier unit.The experiment results obtained demonstrate the success of this instrument in principle and show that it has many advantages of high senstine,wide rang,small size and low price.
