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 for transforming ac voltage and current to transmit ac power. The electric energy transmission is realized according to the principle of electromagnetic induction. The use of the transformer can be divided into a power transformer, a test transformer, an instrument transformer and a transformer with special purposes: the power transformer is necessary equipment for power transmission and distribution and power distribution of power users; a device for performing a withstand voltage (boost) test on the electrical device by the test transformer; the transformer for the instrument is used for electrical measurement and relay protection (PT, CT) of a power distribution system; the transformers for special use include electric furnace transformers for smelting, electric welding transformers, rectifier transformers for electrolysis, small-sized voltage regulating transformers, etc.

A power transformer is a stationary electric device that is used to change an ac voltage (current) of a certain value into another voltage (current) of the same frequency or different values. When the primary winding is supplied with alternating current, alternating magnetic flux is generated, and alternating magnetic flux induces alternating electromotive force in the secondary winding through the magnetic conduction of the iron core. The secondary induced electromotive force is related to the number of turns of a secondary winding, namely, the voltage is proportional to the number of turns. The main function is to transmit electrical energy, and thus the rated capacity is its main parameter. The rated capacity is a conventional value representing the power, which is a value representing the amount of transmitted electric power, expressed in kVA or MVA, from which the rated current, which does not exceed the temperature rise limit under prescribed conditions, is determined when the rated voltage is applied to the transformer. The power transformer which saves energy is an 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 is a core problem to be considered in the whole design process. When the product structure is arranged, the amorphous alloy iron core is not influenced by external force, and meanwhile, the characteristic parameters of the amorphous alloy are 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 by alternating magnetic field and work according to electromagnetic induction principle. The installation position of the transformer is considered to be convenient for operation, maintenance and transportation, and a safe and reliable place is selected. The rated capacity of the transformer must be reasonably selected when using the transformer. When the transformer runs empty, larger reactive power is needed. These reactive powers are to be supplied by the power supply system. If the capacity of the transformer is too large, initial investment is increased, the transformer is enabled to be in no-load or light-load operation for a long time, the specific gravity of no-load loss is increased, the power factor is reduced, and network loss is increased, so that the operation is neither economical nor reasonable. The capacity of the transformer is selected to be too small, so that the transformer is overloaded for a long time, and equipment is damaged. Therefore, the rated capacity of the transformer should be selected according to the requirements of the electric load, and is not suitable to be too large or too small.

The transformer in the prior art has a plurality of defects in the using process, for example, the transformer in the prior art is generally in rigid connection with the mounting seat, a buffer structure is lacked, the transformer is easy to damage the internal structure of the transformer in the vibrating process, structural noise can be generated between the transformer and the mounting seat due to the vibration force generated by the transformer, and the rest of residents nearby is influenced by the volume of the noise.

Accordingly, a transformer damping device is proposed.
