3500/53 超速检测模块 测量电源控制的启动脚是否有启动电压

3500/53   超速检测模块 

3500系列的Bently Nevada电子超速检测系统机械检测系统提供了高度可靠快速响应、冗余专门用作超速部分的转速表系统保护系统。它是为满足美国人的要求而设计的石油学会(API)关于超速的标准670和612保护。3500/53模块可以组合成2取2或3取2(推荐)投票制。超速检测系统要求使用带冗余的3500机架电源。

5).干接点输出方式
监控模块通过信号转接板提供8组告警干接点输出，每组分为常开/常闭触点。在告警事件发生前，事先对每个干接点进行配置，将不同的干接点分别对应为某个告警类型或某组按逻辑关系构成的告警类型组3500/53   超速检测模块 这样，一旦这个告警事件或满足逻辑关系的一组告警事件发生时，干接点将动作，向外界发出告警。

开关电源没有输出，当我们遇到这个问题时，需要检查保险管是否正常，如果正常情况下开关电源不工作或进入保护状态。此时，我们需要测量电源控制的启动脚是否有启动电压。如果没有启动电压或启动电压过低，需要检查启动电阻和启动脚外部元件是否泄漏。如果电源控制正常，故障问题很快就会被发现。如果有启动电压，3500/53   超速检测模块 则需要测量启动时电源控制的输出端是否有高低电源跳转。如果没有跳转，则表明电源控制不良或振荡电路元件和保护电路存在问题。若有跳变，一般由开关管不良或损坏引起。

3500/53   超速检测模块 

133292-01 is a low-voltage DC power input module developed by Bentley Nevada. This component is one of the 3500/15 power modules. The input voltage rating is 88 to 140 Vdc.
The 133292-01 feature 3500/15 series power supply must be installed in a specially designed slot on the left side of the rack. The 3500 rack can accommodate one or two power sources (any combination of AC and/or DC), and any power source can power the entire rack. If a second power supply is installed, it will serve as a backup power supply for the main power supply. When two power supplies are installed in a rack, the lower power supply serves as the main power supply and the upper power supply serves as the backup power supply. As long as a second power supply is installed, removing or inserting any power module will not interrupt rack operation. The 3500 power supply accepts various input voltages and converts them into voltages that other 3500 modules can use. For the 3500 series mechanical protection system, there are three power supply versions to choose from: 1. AC power supply, 2. Voltage DC power supply 3.
