G-L英语词汇 发电机组专业术语

G

Gateway

A device that acts as an interface between two different communication protocols. The Network Gateway Module (NGM) provides a communication protocol that a PC can understand. Other gateway devices may be used to interface between our Lontalk protocol and other systems such as a SCADA or Building Automation System. Typically, a gateway becomes necessary when a SCADA or BAS does not have a driver developed for Lontalk.

网关，是两个不同的通讯协议之间的接口，网关模块（NGM）提供了个人电脑可理解的通讯协议。其他网关设施可能被用作我们的Lontalk 协议和其他系统（如SCADA或楼宇自动化系统）之间的接口装置。当SCADA或楼宇自动化系统没有Lontalk的驱动时，网关就是必不可少的。

Generator

A generator is a machine which converts rotating mechanical energy into electrical energy.

发电机，是把（旋转）机械能转化为电能的装置。

Genset Communication Module (GCM)

The GCM provides a communication gateway between the Model 3100 PowerCommand Control (PCCI) and the network. The GCM communicates with the PCCI control over a serial data link. The GCM gets data from the PCCI controls such as voltage, current, engine speed, oil temperature, etc. and then sends it out on the network if another network node is bound to it or requesting data.

机组通讯板(GCM)，是PCC3100 控制器和网络之间的通讯接口。GCM 与PCC通过串行数据连接。GCM从PCC得到如电压、电流、发动机转速、油温等，再把它们发送给需要这些信息的网络节点。

Governor

A governor is a device on the engine which controls fuel to maintain a constant engine speed under various load conditions. The governor must have provision for adjusting speed (generator frequency) and speed droop (no load to full load).

调速器，是安装在发动机上的一个装置，在不同的负载条件下通过控制燃料量来保持发动机的恒定转速。调速器必须具备转速调整（发电机频率）和降速降调整（零负荷到满负荷）功能。

Grid

The utility-owned power distribution system.

电网，是指电厂的电力输送系统。

Ground

A ground is a connection, either intentional or accidental, between an electrical circuit and the earth or some conducting body serving in place of the earth.

接地，是电路与地渺幡巍怼啤笑桅痞兀地面上的导体的连接，可以是有意的也可以是意外的。

Ground Fault Protection

This function trips (opens) a circuit breaker or sounds an alarm in the event that there is an electrical fault between one or more of the phase conductors and ground (earth). This ground fault protection function may be incorporated into a circuit breaker.

接地故障保护。当一个或多个相导线与地之间出现电气故障时，接地故障保护通过跳脱断路器或报警来示警。这种功能可以一体化设计在断路器上。

H

Hertz (Hz)

The term Hertz is the preferred designation for cycles per second (CPS) and is used to describe frequency.

赫兹，是频率单位，也等于周期/秒(CPS)。

Hub

A common connection point for devices or nodes in a network or sub-network. Hubs are commonly used to connect segments of a LAN and contain multiple ports.

分支器，是网络或子网络中设备和接点的集线器，包含很多端口，一般应用于连接局域网的分支。

Hunting

Hunting is a phenomenon that can occur upon load changes in which the frequency or the voltage continues to rise above and fall below the desired value without reaching a steady-state value. It is caused by insufficient damping.
