Comparison between Open Frame Diesel Generator Set and Silent Diesel Generator Set

Open frame and silent diesel generator sets are two different types of units, and their main differences lie in design, noise level, reliability, and price. Let's take a look at the differences between the two, let's take a look together! 1、 Open frame generator set 1. Firstly, an open frame diesel generator set is usually a more traditional type of generator, designed to install the engine and generator on an open frame. It can be simply understood as a regular or standard model, easy to move and lightweight; 2. This design makes maintenance and repair easier as various components can be directly accessed and repaired. In addition, the structure of the open frame generator is simple and easy to produce, so the price is relatively low. 3. However, open frame generator units do not have sound insulation covers outside, and the noise level is usually high because they do not have any sound insulation or shock absorption measures, and do not have good waterproof, windproof, and dustproof performance. 4. Open shelf is mainly suitable for use in environments with low noise requirements. For example: outdoor construction, construction sites, outdoor operations. 2、 Silent generator set 1. Silent diesel generator set is a more advanced and modern type of generator. Its design is aimed at providing higher reliability and lower noise levels. It can be simply understood as having a box like appearance, low noise, with wheels or trailers, and a heavier weight; 2. Silent units typically adopt a closed structure, including an engine compartment and one or more generator compartments. This design can effectively reduce noise and vibration, while providing better waterproof, windproof, and dustproof performance. 3. In addition, silent units are usually equipped with various sensors and control devices, which can automatically operate and monitor the working status of the generator. This design can improve the reliability and stability of the unit, reduce the possibility of human errors and equipment failures. 4. Silent units are mainly used for vehicle use, RV modification, advertising vehicles, medical vehicles, offices, residential areas, and so on.

Advantages of high-voltage generators

Compared to low-voltage generators, high-voltage generators have the following advantages: 1. The power of a generator can reach several kilowatts, or even tens of thousands of kilowatts. This is because when outputting the same power, the current of a high-voltage generator can be much smaller than that of a low-voltage generator. Therefore, high-voltage generator windings can use smaller line diameters. Therefore, the stator copper loss of high-voltage generators will also be smaller than that of low-voltage generators. For high-power generators, when using a low-voltage power source, a larger stator slot is required because thicker wires are needed, resulting in a very large diameter of the stator core and a larger volume of the entire generator. 2. For large capacity generators, the overall investment in the power supply and distribution equipment used by high-voltage generators is smaller than that of low-voltage generators, resulting in lower line losses and a certain amount of electricity consumption savings. Especially, the 10KV high-voltage generator can be directly used in the power grid, so the investment in power equipment will be reduced, the use will become simpler, and the failure rate will be reduced.

5 major differences between high-voltage generators and low-voltage generators

The main difference between high-voltage generator sets and low-voltage generator sets is the difference in voltage. Generally speaking, low-voltage generator sets are Refers to the commonly used 230V/400V generator sets in the current market. The motor components of the high-pressure diesel generator are according to customer requirements Customized, generally 6300V, 10500V, and 15000V. 1、 The difference between the two 1. Delaying aging Low voltage current is 26 times higher than high voltage current, leading to a significant increase in thermal load loss and equipment damage. 2. High harmonic resistance The harmonic resistance of low-voltage generator sets is lower than that of high-voltage generators; Compared with the overall high-pressure oil engine, the pressure oil engine has strong nonlinear load capacity. 3. Low risk factor of non synchronous short circuit Due to asynchronous power supply systems, there is a risk of asynchronous short circuits when multiple low-voltage generators are not powered in parallel. 5. Centralized power supply Low voltage generators, due to the use of a large number of cables, suffer from high heat loss and cannot achieve power supply. High voltage generator sets have high voltage regulation accuracy, good dynamic performance, small voltage waveform deformation, high efficiency, and long service life With its advantages and popularity among users, it has been widely used

What is the working principle of the trailer generator set

A trailer generator set is a mechanical device that converts other forms of energy driven by turbines, steam turbines, diesel engines, or other power machines into electrical energy. The energy generated by water, airflow, fuel combustion, or nuclear fission is converted into mechanical energy, which is then converted into electrical energy by a generator. The diesel engine of the trailer generator set is the output part of the power, using diesel as fuel. It burns and compresses the high-temperature and high-pressure air formed in the cylinder to inject mist diesel, causing it to expand and convert heat into mechanical energy. Through the four processes of intake, compression, operation, and exhaust, the working cycle is completed, also known as a four stroke engine. In order to reduce the temperature of the parts, the main body is filled with water channels, and the pump is called a water-cooled device. Low power engines also use air cooled engines, called air-cooled machines. At present, the problem of power shortage in China is becoming increasingly prominent, and the requirements for environmental protection are also increasing. As a backup power source for the power grid, silent RV generators with quiet speakers have low noise and are widely used. A silent RV generator with a silent speaker can achieve a noise level of 30dB, but there are significant differences between Chinese and foreign products. The silent speaker for diesel generators comprehensively utilizes various noise reduction technologies, reducing the noise from 108dB to below 75dB and improving the noise reduction effect. To effectively control noise, first analyze the occurrence and distribution of equipment noise, and use targeted noise control techniques.

Analysis of Noise Problems in Open Frame Generators

1、 Noise source The main sources of noise during the operation of an open frame generator include the engine, fan, exhaust pipe, oil pump, and mechanical noise. Among them, the noise generated by engine vibration is obvious and difficult to solve. 2、 Influencing factors The noise level of an open frame generator is influenced by the following factors: 1. Generator power size: Generally speaking, the larger the power generation of an open frame generator, the greater its noise will be. 2. Engine efficiency: Engines with lower efficiency will generate more vibration and noise, so the efficiency of an open frame generator engine will also have an impact on noise. 3. Environmental noise level: The noise level of an open frame generator is also related to the surrounding environmental noise level. If the environmental noise is large, the noise generated by the open frame generator will also increase accordingly.
