Dual Voltage Three Phase Cast Resin Dry Type Transformer
Product Description
Transformer Description:
Dry Type Split winding transformer refers to a multi winding power transformer composed of one high-voltage winding and two or more low-voltage windings with the same voltage and capacity per phase. The normal power transmission of split transformers only occurs between high and low voltage windings, and in the event of a fault, it has the function of limiting short-circuit current.
Pearl Electric design and produce dry-type split transformer with high reliability and stability, suitable for various harsh environments in power systems, and has the following characteristics:
1-Adopting a dry design with high insulation level and dust-proof and moisture-proof ability
2-Without oil, so there is no risk of fire in oil immersed transformers, and there is no need for routine maintenance and oil replacement operations.
3-The total capacity of each split winding in a dry-type split transformer is the rated capacity of the split transformer. Usually, the low-voltage winding is divided into two or three branches as a split winding, with the line end marked with lowercase letters and numbers. The non-split high-voltage winding is composed of two parallel branches, with the line end markings unchanged. The total capacity of each split winding is the rated capacity of the split transformer.
Transformer Applications:
Pearl Electric provides reliable and stable dry-type split transformers in multiple fields. The following are some common application scenarios:
1-Photovoltaic power generation field: In photovoltaic power plants, dry-type split transformers are often used to convert the direct current generated by solar panels into alternating current, which is then integrated into the grid through a step-up transformer. This type of transformer can meet the needs of large-scale photovoltaic power generation; improve the stability and reliability of the power system.
2-In the field of hydrogen production: Dry split transformers have also been widely used in hydrogen production and storage systems. Dry split transformers are used to convert water electrolysis into hydrogen and store it in underground gas storage facilities. This type of transformer can improve electrolysis efficiency, control the direction and speed of electrolysis reactions, and ensure the safe operation of the equipment.
3-Power system distribution: In the distribution system, dry-type split transformers are usually used as main transformers to convert high voltage into low voltage suitable for industrial, commercial, residential and other places. This type of transformer can meet the needs of different voltage levels, improve power quality, and ensure the stable operation of the power system.
4-Special industrial applications: In certain special industrial applications, such as metallurgy, mining, petrochemicals, etc., dry-type split transformers also play an important role. In these fields, dry-type split transformers can meet special working environments and equipment requirements, providing reliable power supply and protection.

Transformer Chracteristics
Transformer Core
1. The core is made of high quality grain-oriented cold-rollled silicon steel of high magnetic conductivity, by using 45°five-step overlapping method to reduce the no-load loss and no-load current.
2. Simulation analysis method is applied for the core design, thus to precisely and effectively calculate the vibration frequency and scale.
3. Flexible connections are adopted between the core and coils, core and clamps. With these measures, transformer's noise level has been improved by 10-15dB over the conventional products.
Transformer Windings
LV windings
1. For LV windings above 400 kVA capacity, superior foil conductors are adopted for winding manufacturing, thus to obtain better amper-turn balance and less transverse magnetic flux leakage, and finally to greatly improves transformer's anti-short circuit capability.
2. By reasonably designing the oil passage within the winding, winding's heat dispersion effect is greatly increased. Thus the reasonable design has decreased temperature rise and improved products' overload capability.
HV windings
1. HV windings are manufactured with superior wire conductors, insulated reinforced with fiber glass.
2. The HV windings are cast under vacuum and high pressure conditions in Germany HUBERS vacuum Cast Machine, resulting the best resin penetration and very low partial discharge( partial discharge for 11kV product could be lower than 5Pc).
3. Optimized structure is adopted for HV windings to improve transformer's electric field. Lighting impulse simulation calculation was adopted for winding model design, thus to substantially improve product's anti-lighting capability.
