產(chǎn)品概述

Resin insulated dry-type transformers are our companys introduction of advanced foreign technology and independently developed SC10, SCB13 series and SC11, SCB18 series thin-insulated dry-type transformers with fillers. Because the coils are encapsulated by epoxy resin, they are refractory, fireproof, explosion-proof, It is maintenance-free, pollution-free, small in size and can be installed directly in the load center. At the same time, the scientific and reasonable design and pouring process make the product smaller in partial discharge, low in noise, and strong in heat dissipation. It can operate at 125% rated load for a long time under forced air cooling conditions, and is equipped with an intelligent temperature controller to prevent faults. Alarm, over-temperature alarm, over-temperature trip box and black box functions, and connected to the computer through the RS485 serial interface, which can be monitored and controlled centrally.

Because our companys dry-type transformers have the above characteristics, they are widely used in power transmission and transformation systems, such as hotels, airports, high-rise buildings, commercial centers, residential areas and other important places, as well as subways, smelting, power plants, ships, ocean drilling platforms, etc. Places with harsh environment.

High voltage winding

The high-voltage winding is vacuum cast with filled epoxy resin, which has small partial discharge and high electrical strength of the coil. The inner and outer walls of the winding are reinforced with fiberglass mesh plates, which increases the mechanical strength of the coil and improves the products ability to withstand sudden short circuits. The coil is permanently Does not crack.

Low voltage winding

The low-voltage winding adopts a foil structure, which solves the problem of axial helix angle when winding with wire and makes the ampere-turn more balanced. At the same time, the coil adopts axial cooling air duct to enhance the heat dissipation capacity. DMD epoxy resin pre-impregnation is used between the winding layers. Cloth, solidified and formed as a whole.

iron core

The iron core is made of imported high-quality cold-rolled silicon steel sheets, with a three-level fully oblique joint structure. The core columns are bound with F-grade weft tapes, and the surface of the iron core is encapsulated with epoxy resin, which reduces no-load loss, no-load current and the iron core. Noise, clamps and fasteners have been specially surface treated to further improve the appearance quality of the product.

Temperature control system and air cooling system

A cross-flow top-blown cooling fan is used, which has the characteristics of low noise, high wind pressure, and beautiful appearance, which enhances the overload capacity of the transformer. The temperature control adopts intelligent temperature controller, which improves the safety and reliability of transformer operation.

Protective enclosure and outlet busbar

The protective shell provides further safety protection for the transformer. The protection levels include IP20, IP23, etc. The shell materials include aluminum alloy, cold-rolled steel plate, stainless steel, etc. for users to choose.
Low-voltage outlet standard busbar outlet line, both side outlet and top outlet are available, and special outlet methods can also be designed for users.
