一、前言用振动监控大功率电气设备,如发电机和变压器,由于绝缘和抗电磁干扰性的要求,尚有一些困难。但是使用光纤传感器,问题便可迎刃而解。光纤传感器可置于测量位置,不用电线即可进行遥控。除了这些特点以外,光纤传感器的紧凑性、可靠性、弥补了传统的压电 I. Introduction Vibration monitoring of high-power electrical equipment, such as generators and transformers, due to the insulation and anti-electromagnetic interference requirements, there are still some difficulties. However, the use of fiber optic sensors, the problem can be solved. Optical fiber sensor can be placed in the measurement position, without wires to remote control. In addition to these features, the compactness and reliability of optical fiber sensors make up the traditional piezoelectric
