便携式继电保护试验电源设计

Design of portable relay protection testing power supply system

便携式继电保护试验电源,作为电网集中式供电试验电源的重要补充,不仅能够提供稳定高效的直流电源,同时满足各类小型分散试验现场作业要求。根据继电保护装置负载特性要求,提出一种能够承受瞬时功率的试验电源系统方案,并进行分模块介绍和数据测试,具有一定的工程实用价值。

Portable power relay protection test supply, as an important supplement of grid centralized test power supply, not only can provide a stable and efficient DC power supply, at the same time meet the requirements of all kinds of small scattered field test site. In accordance with the requirements of relay protection device load characteristic, a kind of instantaneous power to bear test power system solutions is proposed, and points module and data testing are introduced, it has engineering practical value.
