Description

High-performance energy-saving environment-friendly high-pressure power transformer

Technical field

The utility model relates to power equipment, specifically is a kind of high-performance energy-saving environment-friendly high-pressure power transformer.

Background technology

Produce and the too busy to get away electric power energy of life, and power transformer is an indispensable key equipment in the electric power energy utilization that the quality of power transformer performance directly influences the conversion efficiency of electric energy and the quality of electric energy.

Existing common electric power transformer adopting iron core material capability is not good, iron core is saturated easily, and the three-phase exciting curent produces third-harmonic component behind the core sataration, and the not good no-load current that also causes of iron core material capability is also bigger, transformer heats up and consume electric power, reduces conversion efficiency.Loss and three-phase voltage deviation that while distribution imbalance is brought, voltage, electric current, the phase angle imbalance changes, and harmonic content also can increase.

The utility model content

The utility model provides a kind of high-performance energy-saving environment-friendly high-pressure power transformer at the above-mentioned defective of prior art, to improve energy conversion efficiency and to eliminate electropollution.

In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:

A kind of high-performance energy-saving environment-friendly high-pressure power transformer comprises primary coil, secondary coil, transformer core, and described primary coil and secondary coil are for intersecting mutual coiling, and described transformer core is the efficient amorphous alloy iron core of soft magnet performance.

As can be seen from the above technical solutions, the utility model adopts efficient amorphous alloy iron core, this iron core is compared with common silicon steel plate core to have high magnetic permeability, has low-loss, low excitation, iron loss is about common iron core 1/5, excitation loss is about common iron core 1/10, and noise is lower than equal power transformer.Owing to adopt cross complementary coiling mode, when elementary newly-increased electric current and load current change, produce the magnetomotive force increment that offsets with the secondary winding magnetomotive force, to guarantee that main flux is constant, can not change with secondary current because of primary current.Therefore the utility model can lower uncharge loss significantly; eliminate the phase angle energy imbalance that the electricity consumption imbalance causes; can reduce energy waste, reduce consumption; can suppress mains by harmonics again; clean electrical network; improve power factor, reduce the phase difference between the voltage and current, the high-performance energy-saving and high-pressure power transformer of protection power consumption equipment.

Embodiment

Below in conjunction with embodiment the utility model is described in further detail.

Embodiment one: referring to shown in Figure 1, the utility model comprises primary coil A, B, C three-phase, secondary coil a, b, c three-phase, efficient amorphous alloy iron core T; The A of input coil 1, B, C three-phase respectively around the home on Ta, the Tb of transformer core T, Tc post, then according to the slave part that calculates the A phase around the home on the Tb post, on the Tc post, C phase ancillary coil is around the home on the Ta post around the home for the slave part of B phase; In like manner, around the home on Ta, the Tb of transformer core T, Tc post, according to going out the ancillary coil number of turn as calculated, the slave part of a phase is around the home on the Tb post then respectively for a of output winding 2, b, c three-phase, on the Tc post, c phase ancillary coil is around the home on T a post around the home for the slave part of b phase.

Embodiment two: referring to shown in Figure 2, it comprises primary coil A, B, C three-phase, secondary coil a, b, c three-phase, efficient amorphous alloy iron core T; Around the home on Ta, the Tb of transformer core T, Tc post, just A, B, the C three-phase of input coil do not carry out the cross complementary coiling respectively for the A of input coil, B, C three-phase; The a of output winding, b, c three-phase carry out cross complementary coiling design.

Embodiment three: referring to shown in Figure 3, comprise primary coil A, B, C three-phase, secondary coil a, b, c three-phase, efficient amorphous alloy iron core T; Around the home on Ta, the Tb of transformer core T, Tc post, just A, B, the C three-phase of input coil carry out the cross complementary coiling respectively for the A of input coil, B, C three-phase; The a of output winding, b, c three-phase do not carry out cross complementary coiling design.

The utility model is through above technology implementation, coil is mutually over against tie lines in each phase place, what produce in the load zero divides the phase place of electric current to oppose mutually mutually, flux is cancelled each other, thereby zero sequence reduces, prevent that simultaneously zero sequence higher harmonic currents a large amount of on the zero line from passing through, like this by the imbalance of not only improving electric current of special winding, also be that phase place opposes mutually, offset flux, the phasic difference of voltage and current is adjusted automatically, thereby reach the effect of improving power factor, improved the distribution transformer degree of balance, improved the quality of power supply, realized energy-conservation.

Above-mentioned specific embodiment is purpose, feature and the effect that is used for describing in detail this creation, for people's bodyguard of being familiar with this type of skill, according to the above description, may do partly change and modification to this specific embodiment, its essence does not detach the spiritual category person of this creation, all should be included in the claim of this case suitable first Chen Ming.
