新型电子速度继电器的研制

Developpment of the New Electronic Velocity Relay

本文分析了传统的电磁感应式速度继电器存在的一些不足之处，阐明了研制的新型电子速度继电器的原理、性能及优点，展示用新产品取代老产品的可能性。

An analysis on the defects of the traditional electromagnetic velocity relay was made in this paper and the principles, behaviours and advantages of the electronic velocity relay newly developed were expla ined. The possibility of using the new products in place of the traditional ones was probed into as well.
