All the instrumentation and control systems used in the power station should be accurately connected to the ground. "Ground" is a common reference point site, which is defined by different names when applied in different situations. In the design of TSI cabinets, there are protective ground and signal ground to avoid noise interference. A correct grounding system can effectively suppress external ...

A steam turbine is a rotary power machine that converts steam energy into mechanical work. It is also called a steam turbine. It is mainly used as a prime mover for power generation. It can also directly drive various pumps, fans, compressors and ship propellers. The safe and stable operation of a steam turbine unit is related to steam balance and energy conservation and environmental protection, ...

Bently Nevada Vibration and Acceleration Module 3500/42 (128229-01, 176449-02) The bently nevada 3500/42M displacement/velocity acceleration monitor can accept 1 to 4 displacement, velocity or acceleration sensor signals. It is a 4-channel monitor that can accept signals from displacement, velocity, and acceleration sensors. By processing these signals, it can complete a variety of vibration and p...

This content will use the Bently 3500 vibration monitoring system, widely used in most power plants, as a template to comprehensively describe the system installation, configuration, commissioning process, and handling of common problems during commissioning. Section 1: Basic Hardware Knowledge of the TSI System The 3500 system provides continuous, online monitoring capabilities, suitable for mech...

3. 3500/20 Frame Interface Module: The Frame Interface Module (RIM) is the basic interface for the 3500 frame. It supports Bentley Nevada's proprietary protocols for frame configuration and retrieving information from the unit. The Frame Interface Module must be placed in the first slot of the frame (closest to the power supply). The RIM can connect to compatible Bentley Nevada communication proce...

6. 3500/40M Displacement Monitor The 3500/40M Proximitor is a 4-channel displacement monitor that receives input from Bentley Nevada displacement sensors. It processes the signals to generate various vibration and displacement measurements and compares the processed signals with user-programmable alarm setpoints. Each channel of the 3500/40M can be configured using the 3500 frame configuration sof...

9. 3500/50 Tachometer Module The 3500/50 tachometer module is a two-channel module that receives signals from eddy current sensors or magnetic sensors (unless otherwise noted) to determine shaft speed, rotor acceleration, or rotor direction. It compares these measurements to user-programmable alarm points and issues an alarm when the alarm point is exceeded. The 3500/50 tachometer module can be pr...
