可穿戴式工频电场测量仪的研制

为减少作业人员检修配电设备时的触电风险,研制一种方便携带的工频电场测量装置十分必要。文章介绍了一种可穿戴式工频电场测量仪的原理及实现方法,并通过试验对其性能进行了验证。靠近带电体时,可穿戴式工频电场测量仪能够通过光电和声音的形式进行报警,提醒配电检修人员勿忘验电流程,改善依靠人眼目测安全距离误差大的现状,可有效地提高携带者安全意识和水平。

Research on the wearable gauge for the power-frequencyelectric field

In order to reduce the risk of electric shock to distribution maintenance staff, it is necessary to develop a portable device for the power-frequency electric field measurement.In this paper, the principle and implementation method of a wearable gauge for the power-frequency electric field is introduced.The performance of the device is also verified through the test.The device can issue a sound light alarm, reminding distribution maintenance staff not to for-get the electrical inspection process when they approach the charged body.The device can improve the present situa-tion of visual inspection of safety distance and effectively improve the safety awareness and level of carriers.
