Since the Japanese nuclear accident, people have paid more and more attention to the safety issues of nuclear power plants. Recently, many media have paid attention to the safety of many domestic and foreign nuclear power plants.Among them, emergency diesel generator sets can increase the nuclear safety margin of nuclear power plants and ensure the safe shutdown of nuclear reactors when the entire plant loses normal and emergency AC power.As we all know, the main cause of Japan's nuclear accident was the complete damage of the backup diesel generator set, which led to the nuclear leak.Therefore, Jiangsu Haixing Power Technology Co., Ltd. has collected an article on 'Application of Additional Diesel Generator Sets in Nuclear Power Plants'.At present, nuclear power plants in most countries and regions in the world, such as France, the United States, South Africa, South Korea and Taiwan, have installed additional diesel generators.China is no exception.Let's listen to the Haixing generator technician's explanation of the function, wiring method, power supply mode, and test method of the additional diesel generator.

It was reported recently that a factory in Jiangyin used a small gasoline generator set to light and keep heating after work due to a power outage in the factory after get off work. As a result, the poisoning incident occurred. After on-site inspection by ambulance staff at the 120 Emergency Center, it was confirmed that the two women were dead. Small generator sets usually generate electricity by burning fuel to generate power. Various fuels are high in carbon content. When the generator is running, it will produce a large amount of carbon monoxide exhaust gas, and it will also consume a lot of oxygen in the environment. Carbon monoxide poisoning caused by generator operation is particularly common in developed countries.

The motor generator set is driven by the motor to rotate the synchronous bear motor by the motor to adjust the output voltage of the generator by adjusting the generator's excitation current. The advantages of this method are sufficient to make even and smooth. It can not be affected by the power and voltage flow. The well can supply a sinusoidal voltage crossing shape (Figure 1).

As a technical expert in the generator set industry, Haixing Power Technology often finds that many customers ignore the adjustment of the oil supply process, which is obviously a bad habit. Therefore, Haixing Power Technology summarizes for you how to adjust the fuel injection advance angle of the generator set?

Haixing Power Technology has created an encyclopedia of technical knowledge about generator sets, and many customers cannot understand the power definition of diesel generator sets. Therefore, our Haixing Power Technology Company will explain it to you. First of all, we understand the power standards of generator sets; the main power of diesel generator sets is also called continuous power or long-distance power. In China, the main power is generally used to identify diesel generator sets, while in the international field, backup power, also known as maximum power, is used to identify diesel generator sets. After observation, our Haixing Power Company found that there are often irresponsible manufacturers in the market who use maximum power as continuous power to introduce and sell generator sets, which has caused many users to misunderstand these two concepts. Secondly, Haixing Power Technology gave an example to illustrate the power of the generator set. In our country, the diesel generator set is nominal with main power, that is, continuous power, and the generator set can be at 24 small

How to parallelize the generator set? What are the requirements and conditions for parallel operation? What are the advantages and advantages of unit paralleling? Haixing Power Technology analyzes parallel technology for customers! Usually, the generator sets are combined organically to achieve theoretical increase in power generation through a parallel system. The power generation of two units must meet three conditions when running in parallel: the same voltage, the same frequency, and the same initial phase. Theoretically, as long as the unit of different models is an electronic speed control system, it can be used to run and generate electricity in parallel.

Many companies are helpless in the face of the problem of cylinder pulling by generator sets. Therefore, Gu Zhiqing, a technical expert from Haixing Power Technology Co., Ltd., came to solve the problem for the public.

Jiangsu Haixing Power Technology Co., Ltd. has been engaged in the generator set industry for many years and has detailed standards for the performance indicators of diesel generator sets. The performance of generator sets is what enterprises are most concerned about. Only generator sets with excellent performance can provide customers with a complete power supply system. 1. Appearance requirements (1) The boundary size, installation size and connection size of the diesel generator set are all subject to factory drawings approved by the prescribed procedures. Our Jiangsu Haixing Dynamics believes that this is very important. If you don't think about it first, the subsequent installation will become a big problem. (2) The welding of the unit should be firm, the welds should be uniform, and there should be no defects such as welding penetration, undercuts, slag inclusions and pores. The welding slag and welding medicine should be cleaned; the paint film should be uniform, without obvious cracks and fall off; the plating layer should be smooth, without leakage plating spots, rust, etc.; the unit fasteners should not be loose. (3) The electrical installation should comply with the circuit diagram, and there should be obvious signs that it is not easy to fall off at the connections of each conductor of the unit. (4) There should be terminals with good grounding

Recently, Haixing Power Technology Company communicated with many customers and found that the customer was very upset about the noise generated by the generator set. So Haixing organized an article on how to deal with the noise in the generator set room according to the customer's question. Q: Where does the noise in the generator room come from? Answer: Jiangsu Haixing Power believes that diesel engine noise is a complex sound source composed of multiple sound sources. According to the noise radiation method, it can be divided into aerodynamic noise, surface radiation noise and electromagnetic noise. According to the reasons for the occurrence, the radiated noise of the diesel engine surface can be divided into combustion noise and mechanical noise. Among them, aerodynamic noise is the main source of noise. 1. Aerodynamic noise is caused by the unstable process of gas, that is, by the disturbance of gas and the interaction between gas and objects. Aerodynamic noise radiates directly to the atmosphere, including intake noise, exhaust noise and cooling fan noise. 2. Combustion noise and mechanical noise

Haixing Power Technology reminds buyers to pay attention to the fact that buying diesel generator sets requires analysis from multiple aspects of the unit in order to purchase satisfactory products with excellent performance and suitable environment. As a professional manufacturer, Haixing Power Technology Company does not focus on profitability and takes a responsible and serious attitude towards customers, helping customers choose the most suitable products. Jiangsu Haixing Power believes that the factors that should be considered when purchasing diesel generator sets include mechanical and electrical performance, unit use, load capacity and range of changes, automation functions, etc. (1) Purpose. Since diesel generator sets can be used in three situations: common use, backup and emergency. Therefore, the requirements for diesel generator sets are different for different uses. Purchasing a communication generator set must meet the requirements specified in G3 or G4 in GB2820-1997, and at the same time, it must be consistent with the 24 performance indicator requirements stipulated in the 'Implementation Rules for the Entering Quality Certification and Inspection of Diesel Generators for Communications'.
