Dry Type Transformer

Product Description

Dry Type transformer series products are safe, flame-retardant, non-polluting, and maintenance-free, and can be used as replacement products for oil-immersed transformers. It is suitable for places with strict fire protection requirements such as high-rise buildings, commercial centers, hospitals, airports, stations, subways, ships, chemical industries, tunnels, mines, and residential areas.

Product Features

It has low loss, low partial discharge, low noise, strong heat dissipation ability, and can operate at 120% rated load under forced air cooling conditions.
It has good moisture-proof performance and can operate under 100% humidity. It can be put into operation without pre-drying after shutdown.
It is safe, flame retardant, non-polluting and can be installed directly in the load center.
Equipped with a complete temperature protection control system to provide reliable guarantee for the safe operation of the transformer. Maintenance-free, simple and convenient installation, low overall operating cost
High reliability, product performance reaches the international advanced level.

Core Manufacturing

The iron core is made of high-quality cold-rolled silicon steel sheets and adopts a 45° fully oblique joint structure.
The iron core is processed using five-step and seven-step advanced production processes, which effectively reduces the no-load loss and noise of the iron core.
The core posts are bound with insulating tape, and in order to prevent moisture and rust, the surface is sealed with insulating paint;
The surface of the iron core clamps and fasteners are treated with anti-corrosion treatment.

Type description

H/V Coi

It is wound with F-class high quality insulated wire and cast with epoxy resin mixture under vacuum (1~3mbar).
Larger capacity coils are equipped with heat dissipation air channels along the axial direction.
During pouring, the resin mixture can completely penetrate into each gap of the coil, eliminating the existence of gaps and effectively suppressing the occurrence of partial discharge.
The partial discharge of the product does not exceed 5pC.

L/VCoil

Foil conductors are wound on an automatic foil winding machine.
Internal welding is performed on the winding machine using argon gas protection welding, with high precision, low welding resistance, and no external welding process.
DMD composite cloth pre-impregnated with F-class epoxy resin is used as interlayer insulation. The upper and lower ends are encapsulated with resin and placed in a curing oven to make it a strong rigid body.
The reactance heights of high and low voltage coils are almost the same, with small additional losses, good heat dissipation and excellent dynamic and thermal stability.

Temperature Controller

Dry-type transformers are equipped with temperature overheating protection devices. The temperature of the transformer is detected and controlled through the Pt100 thermistor embedded in the low-voltage coil, and digital signals are output through the RS232/485 communication interface.
The thermostat patrols to display the three-phase winding temperature during the operation of the transformer or tracks and displays the phase winding temperature with the highest temperature (can be switched at will).
Realize automatic and manual control of the cooling fan start and stop (can be switched at will).
Display, output and remote transmission of over-temperature alarm and over-temperature trip signals.

Enclosure

The classification of shell protection levels is based on the GB4028 standard.
Dry-type transformers generally have no shell protection, which is IP00. According to user requirements, enclosures with protection requirements of IP20, IP23 and other protection levels can be installed.
The IP20 housing prevents objects with a diameter greater than 12mm from entering, providing a safety barrier for live parts.
The IP23 enclosure can prevent water dripping within an angle of 60° from the vertical. There are ventilation shutters on the front and rear walls of this enclosure. This enclosure will reduce the cooling capacity of the transformer and reduce its capacity by about 5%.
Shell materials include: painted steel plate, aluminum alloy, stainless steel, etc. to choose from.

Dual Ratio Transformer

With the continuous improvement of the power level of the power system grid, in order to meet the needs of the current society and reflect the economic operation of the power grid, the emergence of dual-voltage (20-10kV) dry-type transformers greatly adapts to the needs of the current power system grid construction. On the one hand, the transformer can realize conversion to two voltage levels of 10kV and 20kV. On the other hand, it can realize the economic operation of the transformer and reduce the user's one-time investment.

Cooling Fans

The transformer cooling method generally adopts natural air cooling (AN). At this time, the rated capacity can be continuously output. If the user needs, an air cooling system can be configured and forced air cooling (AF) is used. At this time, the transformer output can exceed the nameplate rated load by 20%.
The fan is automatically started and stopped controlled by the thermostat to ensure the cooling effect of the transformer when it is overloaded.

Applied Standard

GB/T10228, GB1094.11, IEC60076-11
Rated HV: 10, 20, 35kV
Vector Group: Dyn11, Yyn0, YNd11, Yd11 Rated LV: 0.4kV~10kV
Insulation Level: LI75 AC35/ LI0 AC3---10/0.4kV LI125 AC50/ LI0 AC3---20/0.4kV LI170 AC70/ LI0 AC3---35/0.4kV

Grounding Transformer

Grounding transformers are usually used to provide an artificial, loadable neutral point for systems without a neutral point for system grounding. The grounding methods include: direct grounding and arc suppression coil or reactor combined grounding, etc. The grounding transformer can have a continuously used secondary winding (low voltage winding) as a substation power supply.

SGB Open Ventilated Dry Type Transformer

This product is produced using NOMEX insulation material approved by UL in the United States. It has the advantages of safety, environmental protection, energy saving, fire and explosion protection, and simple maintenance. Its main performance indicators, such as partial discharge level, no-load loss, load loss, noise, overload capacity, etc., are better than domestic standards. It can be adapted to use in high-humidity environments and can be installed in dirty and humid environments near lakes, seas, and rivers as well as fire protection. Areas with high requirements and heavy loads.

Amorphous Alloy Dry Type Transformer

SCBH15 series amorphous alloy dry-type transformer is a new type of low-loss and energy-saving distribution transformer. This product combines the technical advantages of amorphous alloy transformers and traditional epoxy resin cast dry-type transformers, and adopts a new structural method. This product has the obvious characteristics of low loss. The no-load loss is 70% lower than that of the conventional 10 series dry-type transformer. The product also has the advantages of compact structure, beautiful appearance, low noise, low temperature rise, strong overload capacity, stable electrical performance, and easy maintenance. .
