Description

Transformer shock absorption device

Technical Field

The invention relates to the technical field of transformer vibration reduction, and in particular to a transformer vibration reduction device.

Background technique

A transformer is a static electrical device used to transform AC voltage and current to transmit AC power. It realizes the transmission of electric energy based on the principle of electromagnetic induction. Transformers can be divided into power transformers, test transformers, instrument transformers and special-purpose transformers according to their uses: power transformers are necessary equipment for power transmission and distribution, and power distribution to power users; test transformers are equipment for withstand voltage (boost) tests on electrical equipment; instrument transformers are used for electrical measurement and relay protection of distribution systems (PT, CT); special-purpose transformers include smelting furnace transformers, welding transformers, electrolysis rectifier transformers, small voltage regulating transformers, etc.

A power transformer is a static electrical device that is used to convert a certain value of AC voltage (current) into another or several different values of voltage (current) with the same frequency. When AC is passed through the primary winding, an alternating magnetic flux is generated. The alternating magnetic flux induces an AC electromotive force in the secondary winding through the magnetic conduction of the iron core. The level of the secondary induced electromotive force is related to the number of turns of the primary and secondary windings, that is, the voltage is proportional to the number of turns. The main function is to transmit electric energy, so the rated capacity is its main parameter. The rated capacity is a conventional value that represents power. It is a characterization of the size of the transmitted electric energy, expressed in kVA or MVA. When the rated voltage is applied to the transformer, it is used to determine the rated current that does not exceed the temperature rise limit under specified conditions. The more energy-saving power transformer is the amorphous alloy core distribution transformer, whose biggest advantage is that the no-load loss value is extremely low. Whether the no-load loss value can be guaranteed in the end is the core issue to be considered in the entire design process. When arranging the product structure, in addition to considering that the amorphous alloy core itself is not affected by external forces, the characteristic parameters of the amorphous alloy must also be accurately and reasonably selected during calculation.

The transformer is composed of two or more coil windings wound on the same iron core. The windings are connected by an alternating magnetic field and work according to the principle of electromagnetic induction. The installation location of the transformer should be convenient for operation, maintenance and transportation, and a safe and reliable place should be selected. When using the transformer, the rated capacity of the transformer must be selected reasonably. When the transformer is running at no load, a large reactive power is required. This reactive power must be supplied by the power supply system. If the capacity of the transformer is too large, it will not only increase the initial investment, but also cause the transformer to be in no-load or light-load operation for a long time, increase the proportion of no-load loss, reduce the power factor, and increase the network loss. Such operation is neither economical nor reasonable. If the transformer capacity is too small, the transformer will be overloaded for a long time and easily damage the equipment. Therefore, the rated capacity of the transformer should be selected according to the needs of the power load, and should not be too large or too small.

The transformer in the prior art has many shortcomings during use. For example, the transformer in the prior art is usually rigidly connected to the mounting base and lacks a buffer structure. The transformer is prone to damage to its internal structure during vibration. The vibration force generated by the transformer will also cause structural noise between the transformer and the mounting base, which affects the rest of nearby residents.

Therefore, a transformer vibration reduction device is proposed.

Working principle: When in use, the transformer is fixed to the top of the mounting plate 11 by the connecting bolts 17. When the transformer vibrates during operation, the transformer drives the mounting plate 11 to vibrate in the vertical direction, and the arc-shaped elastic plate 16 deforms to prevent the mounting plate 11 and the transformer from vibrating in the vertical direction, giving the transformer the first buffer force;

When the arc-shaped elastic plate 16 is deformed, the sliding sleeve 12 slides outside the guide rod 1 22, and the spring 21 is deformed to prevent the movement of the sliding sleeve 12, thereby providing the transformer with a second buffer force.

When the roller 4 follows the vibration of the buffer plate 6 to squeeze the inclined surface 7, the two moving blocks 5 move on the guide rod 2 23, and the two moving blocks 5 approach each other to squeeze the spring 3 24. After the spring 3 24 is deformed, it gives the transformer a fourth buffer force;

The end of the telescopic column 902 is hinged to the buffer plate 6, and the end of the fixed housing 901 is hinged to the movable seat 1. When the buffer plate 6 vibrates in the vertical direction, the spring 904 is deformed to give the transformer a fifth buffer force. Under the action of multiple buffer forces, the vibration of the transformer is significantly reduced, which can effectively protect the electrical components inside the transformer. At the same time, when the vibration is significantly reduced, the noise generation is effectively reduced, reducing the interference to nearby residents;
