In recent years, with the progress of technology, as a high-quality choice of household emergency power supply and field travel power supply, the power supply range of the generator set itself is limited 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?

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。

First of all, it is necessary to determine the lightning protection mode of the generator set, 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 after passing through the transformer generally does not need to take lightning protection measures for the generator set. In the lightning area, 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 arresters 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必须进行防雷保护，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 must be protected against lightning, 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，确保人身安全。

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. Pay attention to lightning protection when using generator sets outdoors to ensure personal safety.

很多客户购买柴油发电机组作为备用电源，一年才会用上几次。如果柴油发电机组处于长期停运状态不进行正确保养，将会导致需要使用时却发现发电机启动不了。那么柴油发电机组处于长期停运状态，有什么需要注意的事项呢？

Many customers buy diesel generator sets as standby power supply, which can only be used several times a year. If the diesel generator set is in a long-term shutdown state and is not properly maintained, it will lead to the failure of the generator to start when it needs to be used. So what should we pay attention to when the diesel generator set is in a long-term shutdown state?

一、封存前

1、 Before seal

1、在柴油发电机组使用后，在热态下放尽柴油发电机组润滑油，包括机油滤清器中的机油。因冷却液具有防锈功能，不需要排放。向曲轴箱内加入合格的规定容量的封存油，起动柴油发电机组至怠速，运转1-1.5min即行停车，然后从油底壳中放出封存油。发动机内部封存油为经脱水的CF级15W/40润滑油。

1. After the last use of the diesel generator set, drain the lubricating oil of the diesel generator set in hot state, including the oil in the oil filter. Because the coolant has anti rust function, it does not need to be discharged. Add qualified sealed oil with specified capacity into the crankcase, start the diesel generator set to idle speed, stop after running for 1-1.5min, and then drain the sealed oil from the oil pan. The sealed oil inside the engine is dehydrated CF grade 15W / 40 lubricating oil.

2、清理干净柴油发电机组表面，检查无可见的脏物、油污、锈迹、水迹等，然后用压缩空气吹干；用毛刷将防锈油均匀涂在所有柴油发电机组金属表面机加工表面（即未喷漆的机加工表面）上；注意橡胶件、塑料件及纤维织物类零件表面禁止涂防锈油或防锈油接触。

2. Clean the surface of diesel generator set, check that there is no visible dirt, oil stain, rust, water stain, etc., and then dry it with compressed air; Apply the antirust oil evenly on the metal surface and machined surface (i.e. unpainted machined surface) of all diesel generator sets with a brush; Note that the surfaces of rubber parts, plastic parts and fiber fabric parts shall not be coated with antirust oil or contacted with antirust oil.

注意：附件驱动带轮表面需采取一定防锈措施。

Note: certain anti rust measures shall be taken for the surface of accessory drive pulley.

发动机外部封存推荐使用FD615脱水防锈油或满足下面性能要求的防锈油。

Fd615 dehydrated antirust oil or antirust oil meeting the following performance requirements is recommended for external storage of the engine.

3、断开蓄电池连接线，清洁端子，涂上一层薄油脂，给蓄电池充电。

3. Disconnect the connecting wire of the battery, clean the terminal, apply a thin layer of grease and charge the battery.

4、使传动胶带松弛

4. Loosen the drive belt

5、将所有外露气管、水管或油管管口用防潮纸或气相防锈纸或聚乙烯塑料薄膜胶带进行封口或包扎，整个空气滤清器也应由防潮纸封口或包扎。

5. All exposed air pipes, water pipes or oil pipe orifices shall be sealed or wrapped with moisture-proof paper or vapor phase antirust paper or polyethylene plastic film tape, and the whole air filter shall also be sealed or wrapped with moisture-proof paper.

二、保存期间

2、 Save period

每月进行蓄电池充电。检查蓄电池液面，需要时，添加，然后进行充电。每月用盘车工具盘动曲轴3-4圈。

Charge the battery every month. Check the battery level, add if necessary, and then charge. Turn the crankshaft 3-4 times a month with the turning tool.
