Description

Transformer damping device

Technical Field

The invention relates to the technical field of transformer damping, in particular to a transformer damping device.

Background

A transformer is a stationary electrical device used to transform ac voltage, current and transmit ac power. The electric energy transmission is realized according to the principle of electromagnetic induction. Transformers can be classified into power transformers, test transformers, instrument transformers, and transformers for special purposes, in terms of their use: the power transformer is necessary equipment for power transmission and distribution and power consumer distribution; the device is used for carrying out voltage withstand (boosting) test on electrical equipment by the test transformer; the instrument transformer is used for electrical measurement and relay protection (PT, CT) of a power distribution system; the transformer for special purposes comprises a furnace transformer for smelting, an electric welding transformer, a rectifier transformer for electrolysis, a small-sized regulating transformer and the like.

A power transformer is a stationary electrical device that is used to transform an ac voltage (current) of a certain value into another voltage (current) of the same frequency or different values. When the primary winding is energized with an alternating current, an alternating magnetic flux is generated, and the alternating magnetic flux is magnetically conducted through the iron core, so that an alternating electromotive force is induced in the secondary winding. The level of the secondary induced electromotive force is related to the number of turns of the primary winding, i.e. the voltage is proportional to the number of turns. The main role is to transmit electrical energy, and thus, the rated capacity is its main parameter. The rated capacity is a conventional value for the power delivered, which characterizes the amount of electrical energy transmitted, expressed in kVA or MVA, and is used to determine the rated current which does not exceed the temperature rise limit under defined conditions when a rated voltage is applied to the transformer. The power transformer with relatively low energy consumption is amorphous alloy iron core distribution transformer and has the greatest advantage of extremely low no-load loss value. Whether the no-load loss value can be ensured finally is a core problem to be considered in the whole design process. When the product structure is arranged, besides considering that the amorphous alloy iron core is not influenced by external force, the characteristic parameters of the amorphous alloy need to be accurately and reasonably selected during calculation.

The transformer is composed of two or more coil windings wound on the same iron core, and the windings are connected through an alternating magnetic field and work according to the electromagnetic induction principle. The installation position of the transformer is convenient to operate, overhaul and transport, and a safe and reliable place is selected. When using a transformer, the rated capacity of the transformer must be selected reasonably. When the transformer operates in no-load operation, larger reactive power is needed. These reactive powers are to be supplied by the power supply system. If the capacity of the transformer is selected to be too large, not only is the initial investment increased, but also the transformer is enabled to be in idle load or light load operation for a long time, the proportion of idle load loss is increased, the power factor is reduced, the network loss is increased, and the operation is not economical or unreasonable. The transformer capacity is selected to be too small, so that the transformer is overloaded for a long time and is easy to damage equipment. Therefore, the rated capacity of the transformer should be selected according to the requirements of the electrical load, and should not be too large or too small.

The transformer among the prior art has many weak points in the in-process of using, for example, transformer among the prior art and mount pad are rigid connection usually, lack buffer structure, and the transformer causes the damage to self inner structure easily at the in-process of vibrations, and the shaking force that the transformer produced also can produce structural noise between transformer and the mount pad moreover, and the sound capacity influences nearby resident's rest.

Therefore, a transformer damping device is provided.
