3-Phase Isolation Distribution Transformer for Isolation And Protection

Transformer Description:

Dry type isolation transformer is a special type of transformer mainly used for separating circuits, matching transformers, or measuring circuits in power systems. It is generally used for machine maintenance and repair, playing a role in protection, lightning protection, and filtering. It is widely used in places such as subways, high-rise buildings, airports, stations, docks, industrial and mining enterprises, and tunnels for power transmission and distribution.

Transformer Features:

Pearl Electric design and produce high reliable and stable dry-type isolation transformer, suitable for various harsh environments in power systems, and has the following characteristics:

1. High isolation: Dry isolation transformers can effectively isolate circuits and protect equipment in the circuit from voltage and current interference.

2- High insulation level: Dry type isolation transformers use high-quality insulation materials, which have a high insulation level and can withstand high voltage and strong current.

3. Dust and moisture prevention: Dry isolation transformers do not require oil, so they can effectively prevent dust and moisture.

4- Without oil, they do not have the risk of oil immersed transformers being prone to fire hazards.

5- Maintenance free: As dry isolation transformers do not use insulation oil, routine maintenance and oil replacement operations are not required.

In addition, the various input and output voltages, connection groups, number and position of regulating taps (generally ± 5%), distribution of winding capacity, configuration of secondary single-phase windings, application of rectification circuits, and whether a casing is required for dry-type isolation transformers can be carefully designed and manufactured according to user requirements.

Transformer Applications:

1-Electrical isolation: The isolation transformer achieves complete isolation between the input power supply and output circuit through its structural design, eliminating the influence of ground wire interference and power ripple on the equipment, providing a safe electrical environment, and protecting the equipment from electrical interference and transient overvoltage on the power line.

2-Safety protection: Due to the electrical isolation between the input and output of the isolation transformer, users can operate without being affected by the power supply voltage and current, reducing the risk of electric shock and shock.

3-Stable power supply: Isolation transformers can provide stable output voltage and frequency, ensure the normal operation of equipment, and eliminate the impact of transient voltage and frequency changes in the power grid, thereby providing a stable power supply.

4-Noise suppression and filtering: Isolation transformers can suppress electromagnetic interference and noise in the input power supply, protect equipment from interference in power lines, and also act as filters to reduce high-frequency noise and harmonics in the input power supply.

5-Energy conservation and environmental protection: Isolation transformers usually have high energy efficiency, which can reduce energy consumption, reduce leakage current caused by power compensation, and reduce energy loss and grid load.

6-Voltage conversion: Isolation transformers can achieve mutual conversion between input voltage and output voltage to adapt to voltage differences between different power grids and equipment.

7-Insulation protection: Isolation transformers can provide good insulation performance, completely isolating the input and output power sources, effectively preventing insulation faults that may occur in electrical systems, avoiding leakage current problems in electrical systems, and protecting circuits and equipment from potential damage caused by insulation faults.

8-Avoid electric shock: The design of the isolation transformer ensures that the number of turns of the primary and secondary windings is the same, and the secondary is not connected to the ground. This way, even if there is a potential difference between the primary and secondary windings, there will be no current flowing through the human body, thus avoiding electric shock accidents.
