Generator set is a complete set of mechanical equipment that converts other forms of energy into electric energy. It has low fuel consumption, low emission, low noise, advanced technology, reliable operation, convenient maintenance, long service life, light weight and portability, high emergency efficiency and low comprehensive cost. It is widely used in industrial and agricultural production, national defense, science and technology and daily life.

近年来随着技术进步，作为家庭应急电源及野外出行电源的更好的选择，由于发电机组本身所能供电范围有限，且使用场所可以方便更换；雷雨天气可以放置于户内，但有些时候发电机组是需要在户外使用的，遇到恶劣的天气就会涉及到设备的防雷保护，那么发电机组的防雷保护需要有哪些具体的步骤呢？

In recent years, with the progress of technology, as a better choice for household emergency power supply and field travel power supply, due to the limited power supply range of the generator set itself, and the place of use can be easily replaced; Thunderstorm weather can be placed indoors, but sometimes the generator set needs to be used outdoors. In case of bad weather, the lightning protection of the equipment will be involved. What specific steps do the lightning protection of the generator set need?

一定要先需要确定发电机组的防雷保护方式主要应根据发电机容量的大小、当地雷电活动的强弱和对供电可靠性的要求。

The lightning protection mode of the generator set must be determined first, mainly according to the generator capacity, the strength of local lightning activity and the requirements for power supply reliability.

理论和实践证明，经过变压器再与架空输电线连接的发电机组，只要可靠地保护了变压器，一般就不需要对发电机组再采取防雷保护措施，在多雷区，无架空直配线的特别重要的发电机组，为防止变压器高压侧的雷电波经过变压器危及发电机的绝缘，宜在发电机的出线上装设一组磁吹避雷器。

Theory and practice have proved that as long as the transformer is reliably protected, the generator set connected with the overhead transmission line generally does not need to take lightning protection measures for the generator set. In the thunderstorm area, for the particularly important generator set without overhead direct wiring, in order to prevent the lightning wave on the high-voltage side of the transformer from endangering the insulation of the generator through the transformer, a set of magnetic blow arrester should be installed on the outgoing line of the generator.

直接与架空配电线路连接的发电机组需要进行防雷保护，应根据国家标准设计规范的规定，按不同情况对发电机组绝缘采取不同的防雷保护措施。保护高压旋转电机用的避雷器，一般采用磁吹避雷器，避雷器宜靠近发电机组。在一般情况下，避雷器可装在电机出线处；

The generator set directly connected to the overhead distribution line needs lightning protection, and different lightning protection measures shall be taken for the insulation of the generator set according to different conditions according to the provisions of the national standard design code. The lightning arrester for protecting high-voltage rotating motor generally adopts magnetic blowing lightning arrester, and the lightning arrester should be close to the generator set. In general, the lightning arrester can be installed at the outgoing line of the motor;

如接在每一组母线上的发电机不超过两台，或单机容量不超过500kw，且与避雷器的距离不超过50m时，避雷器也可装在每一组母线上当直配电机中性点能引出且未直接接地时，应在中性点上装设磁吹或普通阀型避雷器。户外使用发电机组一定要注意防雷，以免发生危险。

If there are no more than two generators connected to each group of bus, or the single unit capacity is not more than 500kW, and the distance from the lightning arrester is not more than 50m, the lightning arrester can also be installed on each group of bus. When the neutral point of direct distribution motor can be led out and is not directly grounded, magnetic blowing or ordinary valve type lightning arrester shall be installed on the neutral point. When using generator sets outdoors, be sure to pay attention to lightning protection to avoid danger.
