如何对发电机组防雷保护和长期停运的保养

来源:https://www.huannengpower.cn/ 文章作者:济柴环能 发布时间:2022-11-07
发电机组是将其他形式的能源转换成电能的成套机械设备,它低油耗、低排放、低噪音、技术先进,工作可靠,维护方便、使用寿命长、轻量便携、应急效率高、综合成本低,在工农业生产、国防、科技及日常生活中有广泛的用途。
The generator set is a complete set of mechanical equipment that converts other forms of energy into electric energy. It has low oil consumption, low emissions, low noise, advanced technology, reliable work, convenient maintenance, long service life, lightweight 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 the choice of household emergency power supply and outdoor travel power supply, the power supply range of the generator set itself is limited, and the place of use can be easily replaced; In thunderstorm weather, the generator set can be placed indoors, but sometimes it needs to be used outdoors. In case of bad weather, the lightning protection of the equipment will be involved. What specific steps should be taken for the lightning protection of the generator set?
首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。
Firstly, it is necessary to determine the lightning protection mode of the generator set mainly according to the size of the generator capacity, the strength of local lightning activities 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 for the generator set connected to the overhead transmission line through the transformer, it is generally unnecessary to take lightning protection measures for the generator set. In the lightning prone area, for the particularly important generator set without overhead direct wiring, in order to prevent the lightning wave at the high voltage side of the transformer from passing through the transformer and endangering the insulation of the generator, a group 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;
For lightning protection of generator units directly connected with overhead distribution lines, different lightning protection measures shall be taken for generator unit insulation according to different conditions according to the provisions of national standard design specifications. The lightning arrester used to protect high-voltage rotating motor generally adopts magnetic blowing lightning arrester, which should be close to the generator set. In general, the lightning arrester can be installed at the outlet 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 no more than two generators are connected to each group of buses, or the single unit capacity is no more than 500kw, and the distance from the arrester is no more than 50m, the arrester can also be installed on each group of buses. When the neutral point of the direct distribution motor can be led out and is not directly grounded, the magnetic blow or ordinary valve type arrester should be installed on the neutral point. When using generator set outdoors, pay attention to lightning protection 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 shut down for a long time without proper maintenance, it will be found that the generator cannot be started when it is needed. 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 sealing
1、在一次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 primary diesel generator set is used, drain the lubricating oil of the diesel generator set in the hot state, including the oil in the oil filter. As the coolant has rust prevention function, it does not need to be drained. Fill the crankcase with qualified sealing oil of specified capacity, start the diesel generator set to idle speed, run for 1-1.5 min and then stop the engine, and then drain the sealing oil from the oil pan. The sealing oil inside the engine is the 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 the diesel generator set, check that there is no visible dirt, oil stain, rust, water stain, etc., and then dry it with compressed air; Use a brush to evenly apply the antirust oil on the machined surface of all the metal surfaces of the diesel generator set (that is, the unpainted machined surface); Note that the surface 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 rust prevention 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 engine external storage.
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 battery connecting wire, clean the terminal, apply a thin layer of grease to charge the battery.
4、使传动胶带松弛
4. Slack 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 rust proof paper or polyethylene plastic film tape, and the entire air filter shall also be sealed or wrapped with moisture-proof paper.
二、保存期间
2、 Saving 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 liquid level of the battery, add it if necessary, and then charge it. Turn the crankshaft 3-4 times a month with the turning tool.
