Main Breaker  
A main breaker is a circuit breaker at the input or output of the bus, through which all of the bus power must flow. The

generator main breaker is the device, usually mounted on the generator set, that interrupts the genset''s power output. Main

breakers provide overcurrent protection and a single disconnect point for all power in a switchboard or device.  
主开关  
主开关是在母排输入或输出端的线路断路器,所有的电流都要从那通过。主开关通常安装在发电机组上,用来切断输出电流。主开关能够提供

过电流保护,是配电盘或设备的电源断开点。  
Mains  
Mains is a term used extensively outside of the United States to describe the normal power service (utility).  
市电  
市电是美国以外的区域对常规电力服务的广泛称谓。  
Master Control  
A control section in a typical paralleling system that provides total system metering and the interface point between the

paralleling system and the facility.  
主控制  
主控制是典型的并联系统计量控制设备,也是并联系统与用电设施之间的接口。  
Medium Voltage  
AC system operating voltages from 601 to 15000 VAC.  
中压  
交流电系统中从601 到15000 VAC的电压称为中压。  
Modbus “专用名词”  
An industrial networking system that uses RS-232 serial master-slave communications at data transfer rate of up to 19.2 KBPS.


一种工业网络,它使用RS232主从通讯模式传输数据,最快可达19.2kBPS。  
Modbus Plus  
An industrial networking system that uses token-passing peer-to-peer communications at data transfer rates of one megabit per

second (MBPS). The network media is shielded twisted-pair cable.  
一种工业网络,它使用令牌环点对点通讯模式传输数据,可达一百万位每秒。网络介质使用屏蔽双绞线。  
Modules  
Modules are also called nodes or devices. These are devices such as Genset Communication Modules (GCMs), Control

Communication Modules (CCMs), and Digital Input/Output Modules (DIMs).  
模块  
模块也可以称作接点或组件,例如机组通讯模块(GCMs)、控制通讯模块(CCMs)以及数字输入/输出模块(DIMs)。  
Molded Case Circuit Breaker  
A molded case circuit breaker automatically interrupts the current flowing through it when the current exceeds the trip

rating of the breaker. Molded case refers to the use of molded plastic as the medium of electrical insulation for enclosing

the mechanisms, and for separating conducting surfaces from one another and from grounded (earthed) metal parts. Molded case

circuit breakers usually contain thermal-magnetic trip units, although larger sizes can be equipped with solid state trip

sensors.  
塑壳断路器  
塑壳断路器能够自动切断电流在电流超过跳脱设定后。塑壳指的是用塑料绝缘体来作为装置的外壳,用来隔离导体之间以及接地金属部分。塑

壳断路器通常含有热磁跳脱单元,而大型号的塑壳断路器会配备固态跳脱传感器。

Network  
A collection of Nodes that communicate with one another over a common medium.  
网络  
在共同的介质上互相通讯的接点的集合就是网络。  
Network Data  
A signal that carries messages between nodes. PowerCommand Networks use Manchester Encoding that makes the signal insensitive

to polarity. The signal is transformer-coupled to the network data wire at a rate of 78 KBPS.  
网络数据  
接点之间传送信息的信号就叫做网络数据。PowerCommand 网络利用Manchester编码使信号不受极性影响,信号通过变压器传送到网络数据线的

速度是78 KBPS。  
Network Gateway Module  
A device acting as an interface between a modem or PC and the network wire. The Gateway takes the UTP wire and then provides

an RS-232 port for connection to either a modem or PC.  
网关模块  
网络模块是调制解调器或PC与网络线之间的接口。网关与UTP线相连,并为调制解调器或PC提供了RS-232连接端口。  
Neutral Current  
Neutral current is the current that flows in the neutral leg of a paralleling system. Often, this term is used in reference

to circulating currents or cross currents.  
零线电流  
零线电流指的是通过并联系统零线的电流,在谈及环流电流或者交叉电流时常会提到这个术语。  
Node  
A module that can communicate over the network data to other modules. A module contains a Neuron Chip. Certain devices are

nodes such as Genset Communication Modules (GCMs) and Control Communication Modules (CCMs). Other devices are not nodes, as

they cannot communicate with other devices, but only receive messages. An example is the Network Annunciator Module (NAM).  
接点  
接点是含有神经元芯片的模块,可以通过网络数据与其他模块通讯。有些模块是接点,例如机组通讯模块(GCMs)和控制器通讯模块(CCMs),而

那些只能接受信息,而不能与其它设施实现通讯的模块则不是接点,例如网络示警模块(NAM)。  
Nonlinear Load  
A nonlinear load is a load for which the relationship between voltage and current is not a linear function. Some common

nonlinear loads are fluorescent lighting, SCR motor starters and UPS systems. Nonlinear loads cause abnormal conductor

heating and voltage distortion.  
非线性负载  
电压和电流之间是非线性关系的负载称为非性形负载。一些常见的非线性负载有荧光灯、可控硅电动机启动器以及UPS系统。非线性负载能导致

反常的导体发热和电压畸变。
