气体继电器流速定值测量结果的不确定度分析

Uncertainty Analysis of Constant Flow Rate Measurement Result for Gas Relay

气体继电器是油浸变压器的一种保护装置,当变压器内部故障使油分解产生气体或造成油流冲动超过定值时,气体继电器接点动作,接通指定的控制回路,并及时发出信号或自动切除变压器,以达到保护变压器的目的。为保证气体继电器流速定值测量结果的正确有效,文章针对气体继电器定值测量结果进行了不确定度分析,以供业内同行参考。

The gas relay is a protective device for oil-immersed transformer. When the transformer internal faults make the oil decomposition of gas, the gas relay sends signal or automatic removal of the transformer, the purpose is to protect the transformer. In order to ensure the correct and effective of constant flow rate measurement results for gas relay, the paper analyzes the uncertainty of constant flow rate measurement for gas relay, and provides reference for the industry peers.
