摘　　要：高压仪器设备在使用过程中产生高压工频电场,高压工频电场对人体健康存在风险隐患,而计量人员计量该类仪器设备往往需要近距离、长时间暴露在高压工频电场中。本文以选择较为典型的高压仪器——试验变压器作为被测对象,构建分析模型、制定详细的测试方案,采用高精度场强仪测定试验变压器在计量过程中的工频电场强度,并结合相关国家标准和数学模型,提出了多种抑制和屏蔽方案,通过试验对比了不同方案抑制和屏蔽方案的效果,并提出了相关计量安全防护建议。High-voltage instruments and equipment in the use of the process will produce high-voltage industrial frequency electric field risks to human health, and measurement personnel in the measurement of such instruments and equipment often need to be close, long exposure to high-voltage industrial frequency electric field. This paper selected a high-voltage test transformer as the object to be tested. By constructing an analysis model and formulating a detailed test plan, a high-precision field strength meter was used to determine the power frequency electric field strength of the test transformer in the measurement process, Combined with related national standards and mathematical models, this paper proposed a variety of suppression and shielding schemes, compared the effects of different schemes through experiments,and proposed relevant measurement safety protection suggestions.
