燃气发电机组使用时的接地线要求
燃气发电机组属于一种供电设备,既然是供电设备那么在使用时就会产生电压或电流,因此为了安全起见在给燃气发电机组接线时一定要让它接地,而且还要按照燃气发电机组接地线的要求来操作。
The gas generator set is a kind of power supply equipment. Since it is a power supply equipment, it will generate voltage or current during use. Therefore, for safety reasons, it must be grounded when wiring the gas generator set, and it must be operated according to the requirements of the gas generator set grounding wire.
1、为了人身安全,发电机和开关屏须另接地线,地线面积不小于发电机输出线截面积。地线可接在地下水管或深埋地下的钢板上,保证接地良好,接地电阻不得大于50欧姆。
1. For personal safety, the generator and switch panel must be grounded separately, and the area of the ground wire shall not be less than the sectional area of the generator output wire. The ground wire can be connected to the underground water pipe or deep buried steel plate to ensure good grounding, and the grounding resistance shall not be greater than 50 ohms.
2、外壳是保护接地线,防止外壳带电,中性点的线为工作中线,为4线制中线,一般大型机组要求接地电阻不大于4欧姆。
2. The enclosure is a protective grounding wire to prevent the enclosure from being charged. The neutral point line is the working neutral line, which is a 4-wire system neutral line. Generally, the grounding resistance of large units is required to be no more than 4 ohms.
3、移动发电机工作零线要是不要用的话就不用接,要用的话接到配电箱里面去,保护零线在发电机附近打个桩就可以了。
3. If the working zero line of the mobile generator is not used, it is unnecessary to connect it. If it is needed, it should be connected to the distribution box, and the protective zero line should be piled near the generator.
4、不管单相发电机还是叁相发电机,为了安全还是要接地的。漏电保护器一般情况下会起作用,但是都是有响应时间的,所以保险起见还是先接地。
4. Whether single-phase generator or three-phase generator, it shall be grounded for safety. The leakage protector will work normally, but it has response time, so it is better to ground first for safety.
5、地线接线点安排在燃气发电机组组的底盘末端,须接到合适的地线位置。
5. The ground wire connection point is arranged at the end of the chassis of the gas generator set and must be connected to the appropriate ground wire position.
6、交流发电机接地中线的连接通常由用户安装时决定,当燃气发电机组组作为电源时,中线须直接连到工厂接地线上。
6. The connection of the grounding neutral wire of the alternator is usually determined by the user during installation. When the gas generator set is used as the power supply, the neutral wire must be directly connected to the factory grounding wire.
The grounding wire requirements for the use of the gas generator set have been completed, so that people using the gas generator set will not be easily shocked. The above is the relevant answer to the question. If you have any questions about this, please come to our website Understand!
