5 天然气发电机的使用模型

5. Usage Model of Natural Gas Generators

天然气发电机以固定安装方式在通信基站使用，发电机输出交流电和现有基站交流输入配电箱进行连接。在市电停电的情况下，优先电池供电，待电池放电到一定程度（通过电压检测），天然气发电设备自动启动进行发电，启动后发电机可以带载基站内所有的用电设备。

The natural gas generator is installed in a fixed manner in the communication base station, and the generator outputs AC power and is connected to the existing base station AC input distribution box. In the event of a power outage in the city, priority should be given to battery power supply. When the battery is discharged to a certain extent (through voltage detection), the natural gas power generation equipment will automatically start to generate electricity. After starting, the generator can carry all the electrical equipment in the base station.

天然气发电机自身的自动控制系统具备RS222智能输出接口，可直接接入完善成熟的监控网络。监控中心可以读取天然气发电机的各种运行数据和状态，例如：电压、电流、频率、温度、燃气、油位等信号和告警信息等。

The automatic control system of the natural gas generator itself has an RS222 intelligent output interface, which can be directly connected to a mature monitoring network. The monitoring center can read various operating data and status of natural gas generators, such as voltage, current, frequency, temperature, gas, oil level, and other signals and alarm information.

天然气发电机是固定安装在基站内的，可以考虑应用在以下几种场合：

Natural gas generators are fixed installed in base stations and can be considered for the following applications:

a.便携式柴油发电机无法进入发电的区域。

a. Portable diesel generator cannot enter the area for power generation.

b.对于便携式柴油发电机的噪声比较敏感的地区。

b. It is sensitive to the noise of portable diesel generator.

c.距离发电保障中心较远的基站。

c. A base station located far from the power generation support center.
