电气安全保护装置在TB880E掘进机上的应用

Application of Electrical Protection Devices on TB880E Tunnel Boring Machine

TBM是隧道开挖的工厂化施工机械,其用电设备多,自动化程度高,技术复杂,对电气设备的安全保护要求较高。介绍其中的几项保护装置,如TJB高压电缆快速接头、高压电缆绝缘及接地线连续保护装置、低压母线绝缘监视装置在TBM上的应用。

Tunnel Boring Machine （TBM） is a factory-type tunnel-building construction machine. Due to the numerous electrical facilities on the TBM, the high-degree automation and the complicated technology of the TBM, there are strict requirements for the safety protection of the electrical facilities on the TBM. This paper introduces several safety protection devices, such as TJB high-voltage cable couplers, high-voltage insulation, ground continuity monitor and insulation monitor.
