This charge transfer is due to the mechanical release or closure of the contacts, the contact-to-coil capacitance, and the stray capacitance between signal and relay drive lines. 这种电荷转移是由于触点的机械释放或闭合、“触点-线圈”电容以及信号和继电器驱动线路之间的寄生电容引起的。
Research on the Improvement of Ability on Track Circuit Once Adjusting by Changing Release Factor of Track Relay 利用改变轨道继电器返还系数提高轨道电路一次调整能力的研究
The automatic test system which can measure action time and release time of the relay is designed. 设计了测量继电器动作时间与释放时间的自动测试系统。
In order to improve the ability of once adjusting track circuit, this paper introduces a method of changing the release factor of track relay. 为提高轨道电路一次调整的能力,提出改变轨道继电器返还系数的方法。
These problems should have been discovered after electric network was put into operation in Henan oilfield in 1989. Lots of oil raising engines have stopped because of release of alternating current contactor, too, there have been serious problems in relay protection. 河南油田在运行中发现该配电方式存在局部故障,造成变电所母线残压过低,大量抽油机因交流接触器释放停抽。
