Metal Shock Absorber For Power dry type Transformer High efficiency low no noise high temperature resistance
Foreword
Most of the power transformers are installed in residential areas, commercial buildings, industrial and mining enterprises and other scenes. The problem of noise nuisance of transformers is increasingly serious. People are in 70-90db noise environment for a long time, which has a great impact on hearing and physiological functions.
Solution
In view of the noise and vibration of the transformer, there are two main types of shock absorbers in the current market: spring and rubber.
Advantages of spring shock absorber: the stiffness of spring is close to linear, with the advantages of large load, low natural frequency, durability, etc., and the characteristics of high isolation and low pass;
Disadvantages: the steel spring has poor stability and small damping coefficient, which makes the whole vibration isolation system easy to produce resonance and is not suitable for vibration reduction and shock isolation in complex vibration environment. On the other hand, the steel spring has the phenomenon of "high frequency through current". The transformer vibration source is the basic frequency and double frequency of 100Hz, and the spring cannot effectively isolate this high frequency.
The advantages of rubber shock absorber: rubber is viscous damping material, which has good vibration attenuation effect;
Disadvantages: poor environmental adaptability, and the traditional rubber material has the disadvantages of poor high and low temperature resistance, easy to aging, and elasticity weakening under the long-term heavy load, which makes it difficult to ensure the use performance and reliability of the instrument equipment; The frequency characteristics of the stiffness of rubber shock absorber are complex, that is, the dynamic stiffness changes with the excitation frequency, and the individual properties of the rubber spring stiffness vary greatly, usually the stiffness error is in the range of 10% ~ 20%, which is not conducive to the vibration isolation design of the equipment.
Product introduction
The latest product of power transformer shock absorption and noise reduction-"metal shock absorber"--- Taking the metal wire and rubber as raw materials, the design of regional isolation and reduction is made for the local and overall vibration and noise sources of the transformer. The product has the characteristics of high elasticity and large damping performance of rubber spring, excellent physical properties of metal, and greatly improved the damping efficiency. It is the latest generation of high-tech products for vibration and noise reduction applied in the power industry at present, the fruit of vibration and noise reduction is remarkable.
The metal rubber shock absorber is suitable for high temperature, low temperature, corrosive medium and other environments. By changing the material, diameter, density and other physical parameters of the wire, it has different stiffness, corrosion resistance and damping performance.
The metal shock absorber completely replaces the traditional spring and rubber shock absorption scheme, and significantly improves the noise reduction and vibration reduction effect, service conditions and service life. It is the best solution for the same kind of products in China at present.
