    Precautions for installing fuel tanks in diesel generator sets
    Many provinces are experiencing 'power shortages' before the arrival of summer, and many companies purchase diesel generator sets to prepare for 'power shortages'. Therefore, as summer is coming, Jiangsu Haixing Power reminds customers of the precautions when installing fuel tanks to ensure the safe operation of the unit. Different models of diesel generator sets have corresponding standard fuel tanks and fuel supply systems. There are many types of fuel tank designs, and users can design discrete fuel tanks of various capacities according to requirements. Users can also design their own fuel tanks. When installing the fuel tank of a diesel generator set, users need to pay attention to the following precautions: 1. The fuel tank is stored in a safe location to prevent fire. The fuel tank or oil barrel should be placed separately in a visible place, appropriately away from the diesel generator set. Keep the unit far away, and smoking is strictly prohibited; 2. If the user makes the fuel tank by himself, it should be noted that the fuel tank of the backup diesel generator set is made of stainless steel or steel plate. Do not spray paint or galvanize the inside of the fuel tank, because they will interact with the diesel fuel. A chemical reaction occurs that may

    17 safe operating regulations for generators
      Recently, many big cities across the country have experienced serious power shortages. Judging from the National Development and Reform Commission's early warning of 'power shortage' and the current phenomenon of power rationing gradually spreading across the country, this year's 'power shortage' will be very serious. Currently, power shortages and subsequent power rationing have spread across the country. Various companies have purchased generator sets to generate their own electricity to solve the problem of power shortage. Many companies have rarely used generator equipment before, and may not understand some basic operating specifications of generators. We have sorted out the basic operating specifications for the use of the generator set. I hope everyone will strictly follow the operating specifications when using the generator set to ensure power consumption! For generators powered by diesel engines, the operation of the engine part shall be carried out in accordance with the relevant regulations of internal combustion engines. Before starting the generator, you must carefully check whether the wiring of each part is correct, whether the connecting parts are secure, whether the brushes are normal, whether the pressure meets the requirements, and whether the grounding wire is in good condition. before starting

    Analysis of Partial Discharge in the Insulator of Generator Sets
    [Overview] The insulation system of the generator set is a measure to ensure the safety of the user. Risk factors such as leakage and damage to the insulator are partly caused by the customer's incorrect operation or the influence of the external environment. Unknown parts of the insulator of the generator set Discharge can also cause. Jiangsu Haixing Power systematically explains the secrets to everyone. 1. What is partial discharge of generator set? What are the main forms? Under the action of the electric field, the electric field intensity in local areas of the insulator in the insulation system reaches the breakdown field strength, and discharge occurs in some areas. This phenomenon is called partial discharge (Partial Discharge). Partial discharge only occurs locally in the insulation and does not penetrate the entire insulation. There are three main types of partial discharge in the generator set: internal discharge of the winding main insulation, end corona discharge and slot discharge (including slot corona). In addition, there is a kind of hazardous discharge in the generator set, which is caused by the breakage of the stator coil strands or joints.

    [Summary] Solutions to the demagnetization, out-of-step, and oscillation of the generator set
    The three most common problems in excitation generator sets are: loss of excitation, out-of-step, and oscillation. Although Jiangsu Haixing Power has explained these problems before, many customers still have questions. Therefore, this article summarizes the solutions. 'Loss of excitation' 'Phenomena' During the operation of the generator set, after the generator loses excitation due to open circuit, short circuit of the excitation circuit, small excitation current or rotor circuit failure, the relevant indications of the generator and excitation system will react as follows: 1. The rotor ammeter and voltmeter indicate zero or close to zero; 2. The stator voltmeter indicates a significant decrease; 3. The electronic ammeter indicates an increase and shakes; 4. The generator active power meter indicates a decrease and swings; 5. The generator active power The table indicates negative values. The generator loses excitation current during operation, causing the rotor's magnetic field to disappear. This may be caused by the excitation switch accidentally tripping, the exciter or semiconductor excitation system malfunctioning, the rotor circuit disconnection, etc. When magnetism is lost

    Pay attention to the compatibility of high-power UPS when equipped with generator sets
    In recent years, large-scale data centers have grown rapidly and will be applied to more and more high-power UPS. Due to the need to control the amount of batteries used in UPS, the delay time of high-power UPS is basically 15-30 minutes, which requires matching power generation. The unit provides continuous power supply to the equipment.Based on the above reasons, we have to face the problem of matching and compatibility between high-power UPS and generator sets. The following are some personal suggestions for reference for people in the power industry:

    The impact of high or low frequency on the generator set
    When it comes to the frequency of generator sets, many inexperienced customers will think that the higher the frequency, the better. However, the generator set becomes damaged after long-term use. Jiangsu Haixing Power has summarized this technical article for your reference for this type of customers, so that customers can timely detect unit problems during use and reduce maintenance costs. Generally, the frequency of the generator set should not exceed 52.5HZ, which is 5% more than the rated value. Therefore, if the frequency of the generator set is found to be abnormal during use, measures must be taken promptly. When the frequency increases, it is mainly limited by the strength of the rotating machinery. When the frequency is high, the motor speed is high. When the speed is high, the centrifugal force on the rotor increases, which easily causes damage to some parts of the rotor. When the frequency decreases, the following problems will occur: (1) The decrease in frequency causes the rotation speed of the rotor to decrease, which reduces the air volume blown by the fans at both ends, worsens the cooling conditions of the generator, and increases the temperature of various parts. (2) Low frequency

    Brand selection of high-power generator sets
    The quality of the generator set mainly depends on the quality of the engine. The 2000kw generators from high to low are MTU, cummins, Mitsubishi, and domestically produced Jichai. If it is not a particularly important emergency, if you are patriotic, it is recommended to choose domestically produced ones, which are also good to use. Original imported unit brands: Caterpillar, Cummins Electric, Kohler (MTU), MTU and some German assembled units have entered the domestic market, but sales are not large. Domestic assembly is mainly based on Cummins and MTU. Because of their high power, owners are more cautious when choosing. Moreover, the price advantage of domestic assembly is not obvious, and most of them are imported with original packaging. If the main use is 2000kw, the competition is mainly between Caterpillar and Kohler, but the price difference is not big, and most customers will choose Caterpillar.
