3500/42M Proximitor/Seismic Monitor是一款4通道监测仪输入来自邻近和地震传感器， 条件信号提供各种振动和位置的测量，并比较条件信号与用户可编程报警。户可以对每个频道进行编程3500/ 42m使用3500机架配置软件来执行任何以下功能:
●径向振动
●推力位置
●微分膨胀
●偏心.
●REBAM *
咖速度
●速度
●轴
●循环接收区域
3500/42M监视器的主要目的是提供:
1.通过连续比较监测参数来保护机器根据配置的警报设定值来驱动警报。
2.操作和维护的基本机器信息人员。
根据配置，每个通道通常将其输入信号限制为生成各种称为"静态值”的参数。户可以配置告警每个活动静态值的设定值和危险设定值的任意两个活动静态值。
1.变压器损耗增加。变压器一般根据额定容量设计，运行平衡点在67%左右。当变压器负载超过额定容量时，变压器的铜损失会继续增加，增加变压器的损耗。

2.当变压器的输出电压超过变压器的额定容量时，变压器的二次输出电压降低，当输出电流达到短路电流时，电压降至0.

3.变压器的使用寿命会降低。变压器的绕组主要由绝缘材料制成，需要足够高的耐热性。如果温度过高，绝缘材料会加剧老化。而且变压器长期过载运行，会使变压器温度过高，严重时还会导致变压器燃烧3500/42M 176449-02  前置器/地震监视器  变压器能过载吗？答案是肯定的。正常情况下，变压器可以在可承受的负载值内短时间运行，但此时间周期不宜过长。如果长期急救负载运行，变压器的使用寿命会不同程度地缩短，这种运行方式应尽量减少。紧急情况下必须超负荷运行时，还应尽量减少超额定电流运行时间，降低超额定电流倍数。需及时替换正常额定值变压器使用。

那么变压器在什么情况下过载运行是正常的呢？在平均老化率较小的情况下，变压器可以在短时间内超额定电流运行。出现以下情况时，不能超负荷运行。当变压器出现严重缺陷或绝缘弱点时3500/42M 176449-02  前置器/地震监视器  ，变压器不应超过额定电流。应立即更换正常的额定值变压器，因为当此类问题发生时，变压器已经出现故障，此时如果超载运行，会增加变压器故障造成的安全风险。

3500/42M 176449-02  前置器/地震监视器

3500/05-01-02-00-00-00 is a system rack manufactured by Bently Nevada and is part of the 3500/05 series used in mechanical condition monitoring systems. All 3500 display modules and rack power supplies are installed in the Bentley Nevada 3500/05 system rack. It enables 3500 modules to interact with each other, and the power supply can also distribute power to each module as needed.
3500/05-01-02-00-00 Features
Store all 3500 display modules and rack power supplies.
Available in two sizes: full size and mini rack
Provide three different formats: panel mounting, rack mounting, and partition mounting are all options.
Rack position (7 or 14)
Rack size
There are two sizes of 3500 racks available:
Full size rack: 19 inch EIA rack with 14 module slots available
Mini rack: 12 inch rack with 7 module slots available
Panel installation
This rack style is connected to a rectangular cut on the panel, with clips included with the rack.
You can access wiring connections and I/O modules from the back of the rack.
Rack installation
The 3500 rack is installed on 19 inch EIA rails of this rack type.
You can access wiring connections and I/O modules from the back of the rack.
Partition installation
When access to the back of the rack is restricted, this rack type places the rack against a wall or panel. You can access the wiring connections and I/O modules from the front of the rack. This format does not support 3500/05 mini racks.
The rack interface module and power supply must be installed in the leftmost rack position. Any combination of modules can be used for the remaining 14 rack positions (7 rack positions for mini racks).
