继电保护技术在变压器故障解决中的运用研究

Research on application of relay protection technology in transformer fault resolution

变压器作为变电站的核心设备,其运行可靠度是保证变电站安全,稳定供电的有效前提,目前福建煤电股份有限公司供电公司所属的变电站主要有5个35 k V变电站以及各生产矿井的6 k V中央变和采区变。若变压器发生故障,不仅会给企业造成直接经济损失,还会制约电网供电安全,影响矿井的安全生产。因此,保证变压器的正常运行是变电检修运维人员工作中一项尤为重要的工作。针对此,文章以变压器继电保护技术为衡量点,对继电保护技术在变压器故障解决中的运用进行了深层次探究。

As the core equipment of transformer substation, its operating reliability is an effective precondition to ensure the safety and stability of power supply in substations. Currently, Fujian Coal Electric Co., Ltd., a power supply company of the main substation, has five 35 kV substation and 6 kV central transformer and mining area change in various production mines. If the transformer fault occurs, not only it will cause direct economic loss to the enterprise, but also restricts the safety of power network and affects the safe production of the mines. Therefore, it is a very important work for transformer maintenance and repair people to ensure the normal operation of the transformer. For this, based on the technology of transformer relay protection measure, the paper has carried out the deep studies on the application of relay protection technology in transformer fault.
