Natural Gas Generator Power Uniform, Moderate, Mechanical Life Longer
Jul 04, 2017

At present, the communication base station backup power supply mainly rely on small air-cooled diesel generators, the main fuel for diesel. The use of diesel has a lot of inconvenience, such as quality, noise, start and so difficult. Noise to low-frequency noise-based, penetrating power. The engine runs for a long time, the temperature and pressure are higher, the cylinder will produce more soot and carbon deposition, the engine oil is also easy to produce glial, maintenance workload, and the need for regular maintenance. The exhaust gas contains a lot of CO, soot and nitrogen oxides, and the particles of the emissions are large, so it is easy to produce "black smoke".

Natural Gas Generators, to overcome the many shortcomings of diesel generators, such as quiet noise reduction, gas burning clean, less impurities; uniform power, moderate, mechanical life is longer, the exhaust will not be formed in the equipment and the engine room Oil accumulation, is recognized as green energy. The fuel itself is the gas, before burning without vaporization, will not be attached to the combustion chamber and spark plug, no carbon, but will not pollute the oil, reducing the daily maintenance, maintenance costs. Therefore, the application of Natural Gas Generators in communication base stations is broad prospects.

The working principle of a Natural Gas Generator

Natural Gas Generator system to gasoline generator set for the original shape, from the dedicated gas channel input to the engine cylinder, so that the engine power to drive the generator to generate electricity.

The natural gas power generation system is fixedly installed in the mobile communication base station, and uses the gas power generation to automatically supply the three-phase power to the base station equipment according to the intelligent judgment whether the electricity is available or not. The entire system through the air inlet, exhaust to form a relatively closed self-circulation system, the base station of air and temperature has no effect.

2 system of Natural Gas Generator system

The system is mainly composed of gas generator main engine, automatic control system, quiet vibration system and gas system.

2.1 gas power generation host

Gas mainframe works with gasoline generators, through reliable performance improvement and improvement, only the fuel from gasoline into natural gas, the use of mature and stable internal combustion engine technology. Steady and stable output voltage, frequency (steady frequency), fluctuation rate, asymmetrical load off-line voltage deviation, line voltage waveform sine distortion rate, transient voltage (frequency) adjustment rate and settling time are satisfied by generator output. GB requirements.

2.2 automatic control system

With automatic control system, real-time monitoring of the working state of the unit, the real room to achieve unattended.

In addition to the combustible gas sensor in the box, the automatic monitoring system can cooperate with the combustible gas sensor installed in the room to transmit the alarm to the automatic control box, and then cut off the gas pipeline and lock the unit to ensure the safety of the whole room. At the same time automatic monitoring system with the box within the temperature sensor and oil level sensor, close detection unit running state; when the temperature exceeds the safety settings, the unit directly to stop the operation, the implementation of blocking, and cut off the gas pipeline. Through the RS222 interface to accept the mobile operation and maintenance management center management, centralized monitoring of the base station unit running status, including: voltage, current, frequency, temperature, gas, oil level and other signal and alarm information, and by the center as needed direct remote control unit Kai stop.

Automatic control system can achieve the following security protection: overvoltage protection, undervoltage protection, overload protection, frequency protection, gas leakage protection, chassis temperature protection, oil level low protection and cooling water temperature protection.

2.3 silent vibration system

Mute vibration system includes silent vibration chassis and out of the wind muffler, the use of silent system greatly reduces the engine's mechanical noise, with mute the vibration chassis and large duct silencer to meet the high demand for quiet.

In the use of enhanced configuration when the minimum noise up to 45db or less, to meet the requirements of a variety of environments.

2.4 Gas system

The gas system is mainly composed of gas storage tanks and gas control components. In recent years, mature gas cylinder storage technology has created the basic conditions for the promotion of Natural Gas Generators. At present, the use of gas cylinders should meet the requirements of national safety standards.

2.5 Natural Gas Generator use model

The Natural Gas Generator is used in a fixed installation mode at a communication base station, and the generator output AC is connected to an existing base station AC input distribution box. In the case of power failure, the priority battery-powered, until the battery discharge to a certain extent (by voltage detection), natural gas power generation equipment automatically start to generate electricity, after starting the generator can carry all the equipment within the base station.

Natural Gas Generator's own automatic control system with RS222 intelligent output interface, can be directly access to improve the mature monitoring network. The monitoring center can read the running data and status of the Natural Gas Generator, such as voltage, current, frequency, temperature, gas, oil level and other alarm and alarm information.
