Transformers can be divided according to purpose

Transformers can be divided according to purpose: distribution transformer, power transformers, sealed transformers, modular transformers,dry-type transformers, single-phase transformer, electric furnace transformer, rectifier transformers, reactors, interference transformers,lightning transformers, box-type variable electrical transformer test transformer corner. The most basic type of transformer,It includes two sets of wound coil wire, and another said inductively close together. When an alternating current (having a known frequency) flow in one set of coils, the other set of coils in the induction AC voltage having the same frequency, and the induced voltage depends on the two coils and magnetic cross coupling the extent of the chain.

Farady padmount transformer

Farady padmount transformer or pad-mounted transformer is a ground mounted electric power distribution transformer in a locked steel cabinet mounted on a concrete pad. Since all energized connection points are securely enclosed in a grounded metal housing, a padmount transformers or pad-mounted transformers can be installed in places that do not have room for a fenced enclosure. Padmount transformers are used with underground electric power distribution lines at service drops, to step down the primary voltage on the line to the lower secondary voltage supplied to utility customers. A single padmount transformer or pad-mounted transformer may serve one large building, or many homes.

better energy saving power transformers

In order to develop better energy saving power transformers, amorphous alloy core material and amorphous core transformer design and manufacturing process to carry out in-depth research, trial out 100kva power transformer, while such materials used in the epoxy resin dry type transformers, to further promote the improvement of the amorphous alloy core transformer manufacturing level, the formation of amorphous Metal distribution transformer, the power user trial showed that, basically reached the practical requirements.

electric transformer technology

In recent years, strong demand for electric transformer substation, electric transformer technology development goal is a lightweight, high efficiency, high density, chip based products will also be further developed. Due to the continuous development of household appliances and electronic equipment, low voltage electronic converter Pressure is growing demand, therefore, high definition television and high frequency monitors with flyback transformer manufacturer become the main areas of concern, including acyclic flyback transformer demand will have a larger growth; high frequency,low loss,Small size, low cost power transformer will occupy large market; high voltage auto load booster market outlook is encouraging.

Oil Immersed Transformer

Oil Transformers are use in a wide array of applications, and are usually oil immersed transformer. Because of safety reason and the flammability of the oil in the oil type transformer, they are mostly used for outside applications. One of the safety features in an oil immersed power transformer is a sensor to tell if gas is accumulating inside the transformer, which is a sign of an electric arc in the winding. This prevents catastrophic burnout. Below are a list of a few areas where oil filled transformer are used.

Three-Phase auto voltage booster

Applied in the utility’s distribution systems are generally medium-voltage mechanical high voltage auto load booster. It should be noted that there are two distinct types of AC auto load booster: Medium-voltage automatic voltage booster(mechanical) and the Low-voltage automatic voltage booster (mechanical or electronic). The difference in their operation and design clearly demonstrate that their applications are not the same. The latter is intended to protect end-user devices from overvoltage and undervoltage conditions.Nonetheless, this post will focus on the high voltage auto load booster, which is primarily used by the electric utility to compensate for the voltage drop in the feeders or distribution systems.

Single-phase transformer instead of three-phase transformers

Single-phase transformer instead of three-phase transformers, high voltage (10kV) power supply into the residential area of the modern distribution network good distribution model. When application through single-phase transformer used in utility distribution network to fully consider the construction program and run the program, with the economic and technical means to determine a reasonable comparison wiring. In the daily operation and management work, enhance the operation of the transformer monitoring, timely adjust the operating mode to ensure distribution network in economic operation Line Status. To pay attention to the transformation of the existing distribution network, using the extension of the original three-phase high-voltage lines, the increase in the low-pressure end of the single-phase transformers, divided by a low pressure line to maximize cost savings; also expand single-phase transformers varieties, developed prefabricated Type small, single-phase three-phase combination box transformers, transformer dry type single-phase transformer box, expand the application in the new cable cell and other occasions.

dry cast resin transformer

11kv dry type transformer are available in three general classes of insulation. The main features of insulation are to provide dielectric strength and to be be able to withstand certain thermal limits. dry electric transformer insulation classes are 220(degrees) C (Class H). 185 (degrees) C (Class F), and 150 (degrees) C (Class B). Temperature rise ratings are based on full-load rise over ambient (usually 40 (degrees) C above ambient and are 150 (degrees) C (available only with Class H insulation), 115 (degrees) C (available with Class H and Class F insulation) and 80 (degrees) C (available with Class H, F, and B insulation). A 30 (degrees) C winding hot spot allowance is provided for each class of dry cast resin transformer.

Fire-resistant dry transformer and "cast resin" dry transformer

Fire-resistant dry transformer or "cast resin" dry transformer price are well suited for installation in high-rise buildings, hospitals, underground tunnels, school, steel factories, chemical plants and places where fire safety is a great concern. dry transformer price is hazard free to the environment, dry type transformer price have over the years proven to be highly reliable.“Dry type” simply means it is cooled by normal air ventilation. The dry transformer does not require a liquid such as oil or silicone or any other liquid to cool the electrical core and coils of dry transformer price.dry transformer price are voltage changing (Step-up or Step-down) or isolation device that is air cooled rather than liquid cooled. The dry type power transformer price case is ventilated to allow air to flow and cool the coil (coils).

Oil immersed transformer classification and Protection

According to the number of single-phase transformer to distinguish, it can be divided into three-phase transformers and single phase transformer. In a three-phase power system, the general application of the three-phase transformer, when the oversized transport conditions and subject to three phase pad mounted transformer system can also be applied consisting of three single phase pole mounted transformers group. According to the number of windings can be divided into two-winding transformer and three-winding transformers. The transformers are usually two-winding transformer, namely on the core has two windings, one for the primary winding, one for the secondary winding. Three-winding transformer larger capacity transformer (5600 kVA or more) to connect the three different voltage power lines. In special circumstances, also applied more windings.
