一种防误碰新型鳄鱼夹的研究与应用
|
摘要
本文分析了继电保护、高压预试工作中测试线接线存在的问题,在没有改变原有鳄鱼夹的功能上作了创新,设计了一种防误碰新型鳄鱼夹。创新设计的新型鳄鱼夹在继电保护和高压试验两个专业中进行应用测试,通过测试数据分析,新型鳄鱼夹有效解决了继电保护定检、高压预试工作中误碰误接线的问题,整体缩短了工作时间,提高了现场工作的安全效益和经济效益。
The problems in wiring of test line in relay protection and high voltage pre test work are analyzed. Innovation has been made without changing the function of the original alligator clip. A new crocodile clip is designed to prevent accidental touch. A new type of alligator clip is designed for preventing accidental touch. The innovative crocodile clip is applied in two specialties of relay protection and high voltage test. Through the analysis of test data, the new type of crocodile clamp effectively solves the problem of accidental touch and connection in relay protection scheduled check and high voltage pre-test work, shortens the working time as a whole, and improves the safety and economic benefits of field work.
