互感器极性试验综合工器具研制

Development of Integrated Instrument for Transformer Polarity Test

介绍一种新型互感器极性试验综合工器具,该工器具由伸缩式操作杆、高空夹线钳、自动收线轮、微型操作盒等部件组成,具有携带方便、使用长度可灵活调节、全自动收放试验导线等特点。试验人员使用该工器具,无需登高作业,无需特种车辆配合,即可安全、顺利地完成互感器极性试验工作。

A new polarity test integrated instrument, which is composed of two telescopic levers, two high altitude jointing clamps, an automatic reel, an operation box and so on, is designed for vohage and current transformers. This instrument has many advantages such as portability, adjustable length, automatical take-up/pay-off testing line. Polarity tests of voltage or current transformers can be completed using the integrated instrument safely and smoothly without climbing and special vehicles.
