QJZ-1140系列矿用多回路真空电磁启动器的维修策略

The maintenance strategy of QJZ-1140 series multi-loop vacuum electromagnetic starter for coal mines

煤矿井下环境恶劣,存在瓦斯、煤尘、顶板、水、火等危险有害因素,容易引发启动器电气事故,为此,必须掌握启动器的工作原理、结构特点、常见故障及维修策略,保证设备在现场能够安全、高效、平稳运行,确保不因电气故障引发安全事故和影响生产。

The coal mine underground environment is bad, such as gas,coal dust, roof,water, fire and other harnfful factors, which easily lead to electrical accidents of starters. Therefore, it is necessary to master the working principle, structural features, common failures and maintenance strategies of the starter to ensure the safely, efficiency and smooth operation of the equipment in the field, and to ensure that it does not cause safely accidents and influenee production due to electrical faults.
