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?

需要確定發(fā)電機(jī)組的防雷保護(hù)方式主要應(yīng)根據(jù)發(fā)電機(jī)容量的大小、當(dāng)?shù)乩纂娀顒?dòng)的強(qiáng)弱和對(duì)供電可靠性的要求。

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.

理論和實(shí)踐證明，經(jīng)過(guò)變壓器再與架空輸電線連接的發(fā)電機(jī)組，只要可靠地保護(hù)了變壓器，一般就不需要對(duì)發(fā)電機(jī)組再采取防雷保護(hù)措施，在多雷區(qū)，無(wú)架空直配線的特別重要的發(fā)電機(jī)組，為防止變壓器高壓側(cè)的雷電波經(jīng)過(guò)變壓器危及發(fā)電機(jī)的絕緣，宜在發(fā)電機(jī)的出線上裝設(shè)一組磁吹避雷器。

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.

直接與架空配電線路連接的發(fā)電機(jī)組必須進(jìn)行防雷保護(hù)，應(yīng)根據(jù)國(guó)家標(biāo)準(zhǔn)設(shè)計(jì)規(guī)范的規(guī)定，按不同情況對(duì)發(fā)電機(jī)組絕緣采取不同的防雷保護(hù)措施。保護(hù)高壓旋轉(zhuǎn)電機(jī)用的避雷器，一般采用磁吹避雷器，避雷器宜靠近發(fā)電機(jī)組。在一般情況下，避雷器可裝在電機(jī)出線處；

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;

如接在每一組母線上的發(fā)電機(jī)不超過(guò)兩臺(tái)，或單機(jī)容量不超過(guò)500kw，且與避雷器的距離不超過(guò)50m時(shí)，避雷器也可裝在每一組母線上當(dāng)直配電機(jī)中性點(diǎn)能引出且未直接接地時(shí)，應(yīng)在中性點(diǎn)上裝設(shè)磁吹或普通閥型避雷器。戶外使用發(fā)電機(jī)組一定要注意防雷，確保人身安全。

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.

很多客戶購(gòu)買柴油發(fā)電機(jī)組作為備用電源，一年才會(huì)用上幾次。如果柴油發(fā)電機(jī)組處于長(zhǎng)期停運(yùn)狀態(tài)不進(jìn)行正確保養(yǎng)，將會(huì)導(dǎo)致需要使用時(shí)卻發(fā)現(xiàn)發(fā)電機(jī)啟動(dòng)不了。那么柴油發(fā)電機(jī)組處于長(zhǎng)期停運(yùn)狀態(tài)，有什么需要注意的事項(xiàng)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、在柴油發(fā)電機(jī)組使用后，在熱態(tài)下放盡柴油發(fā)電機(jī)組潤(rùn)滑油，包括機(jī)油濾清器中的機(jī)油。因冷卻液具有防銹功能，不需要排放。向曲軸箱內(nèi)加入合格的規(guī)定容量的封存油，起動(dòng)柴油發(fā)電機(jī)組至怠速，運(yùn)轉(zhuǎn)1-1.5min即行停車，然后從油底殼中放出封存油。發(fā)動(dòng)機(jī)內(nèi)部封存油為經(jīng)脫水的CF級(jí)15W/40潤(rùn)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、清理干凈柴油發(fā)電機(jī)組表面，檢查無(wú)可見(jiàn)的臟物、油污、銹跡、水跡等，然后用壓縮空氣吹干；用毛刷將防銹油均勻涂在所有柴油發(fā)電機(jī)組金屬表面機(jī)加工表面（即未噴漆的機(jī)加工表面）上；注意橡膠件、塑料件及纖維織物類零件表面禁止涂防銹油或防銹油接觸。

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：附件驅(qū)動(dòng)帶輪表面需采取一定防銹措施。

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

發(fā)動(dòng)機(jī)外部封存推薦使用FD615脫水防銹油或滿足下面性能要求的防銹油。

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

3、斷開(kāi)蓄電池連接線，清潔端子，涂上一層薄油脂，給蓄電池充電。

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

4、使傳動(dòng)膠帶松弛

4. Loosen the drive belt

5、將所有外露氣管、水管或油管管口用防潮紙或氣相防銹紙或聚乙烯塑料薄膜膠帶進(jìn)行封口或包扎，整個(gè)空氣濾清器也應(yīng)由防潮紙封口或包扎。

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、保存期間

2、 Save period

每月進(jìn)行蓄電池充電。檢查蓄電池液面，需要時(shí)，添加，然后進(jìn)行充電。每月用盤車工具盤動(dòng)曲軸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.
