DESIGN AND PRODUCTION

of dry transformers and electric reactors

DESIGN


Solar System specialists develop transformers of various types for use in solar power engineering for all types of solar power plants.

Dry and oil transformers are successfully operating at solar power plants in Ukraine.

The range of transformers has a number of standard models of dry-type transformers . from 25 to 3150 kVA .

PRODUCTION

Production Solar's special series of cast resin dry-type transformers have exceptional performance in terms of quality standards.

Transformers are intended for the development of technologies for the preservation of the environment.

Production started in 2017.

Temperature

Temperature control of windings is one of the key tasks in the development of any type of transformer equipment. Ensuring reliable and trouble-free operation in any climatic and weather conditions is also the most important task for designers.

The size

High efficiency with compact dimensions is a benchmark that is constantly present in the development of new transformer equipment of any type, both "dry" and oil-immersed transformers.

MANUFACTURE OF MAGNETIC CONDUCTORS
under the order

Step-Lap magnetic cores

Over thirty years ago, Westinghouse Electric invented a new cross-step system to reduce costs. In the design of the Step-Lap magnetic cores, the butt overlap is reduced by almost three times compared to the standard one. In this case, the shift progresses by approximately 6 sheets, before a new cycle. In the design of the system, the most important role is played by the device in which the recess in the yoke moves along its length depending on the number of steps. The length of the central leg remains unchanged.

Benefits

Step-Lap is widely used due to the following benefits:

Reducing the level of loss of the magnetic circuit

Reduced iron consumption

Almost no noise

Reducing the level of loss of the magnetic circuit

Fast assembly

Unlimited plate length

Production technology

The magnetic core is made of electrical steel, the thickness of which varies from 0.23 mm to 0.35 mm. The maximum permissible steel width is 500 mm. Using the latest lines, it is possible, at the request of the customer, to make almost any configuration of this type of product:
- V-shaped stamp;
- Displacement in horizontal and vertical planes with losses minimized.

The core section is made of several steps and its shape is as close as possible to a circle. Noise is kept to a minimum due to the fact that the steel pins pressing the core plates pass through it in the insulated pipes.

Parameters of manufactured products

The width of the magnetic core sheets is from 40 mm to 490 mm. Length up to 4000 mm.

The standard applied thickness of electrical steel is 0.3 mm (possibly 0.23-0.35).

Possibility of punching holes with a diameter of 10, 11, 13, 15, 16, 17, 20, 26, 30 mm or others at the request of the customer.
