100 Kva Single Phase Transformer

30kVA single-phase transformer is a small and medium-sized distribution equipment widely used in rural power grids, commercial buildings, industrial control and other fields. Compared to traditional three-phase transformers or stacked iron core transformers, it has the following significant advantages:

1. Efficient and energy-saving, with low losses

Reduce no-load losses by 35% to 70%: Adopting a coiled iron core structure (such as the D10 series), the magnetic circuit is seamless, reducing hysteresis and eddy current losses, and the no-load current is only 30% of the traditional S7 series. Taking 30kVA as an example, the no-load loss is only 95W, and the annual power saving is 1332kWh (calculated based on 8600 hours of no-load), saving about 666 yuan/year in electricity costs.

39% reduction in load loss: Optimized winding design for lower copper loss, suitable for long-term stable operation.

No need for reactive power compensation: The no-load current is extremely low, and there is almost no reactive power loss, reducing the investment in capacitor compensation devices.

2. Compact structure and flexible installation

Small size and light weight: Adopting dry-type or coiled iron core design, it is lighter than oil immersed transformers of the same capacity, suitable for single pole suspension installation, and saves transformer platform costs.

Suitable for the "small capacity, dense point" power supply mode: shortening the power supply radius (such as the case of Malan Village, with an average of 230 meters), the terminal voltage loss is only 5%, far superior to long-distance power supply.

Single phase three wire power supply reduces line loss by 30%~75%: The middle tap zero line design ensures that the zero line current approaches zero after balancing the load, significantly reducing line loss.

3. Safe, reliable, and highly applicable

Fire and explosion prevention: Dry design (such as DG series), no oil and flammable risks, suitable for fire sensitive places such as subways, hospitals, and shopping malls.

Anti electric shock design: The middle tap on the low-voltage side of the 10kV/230V model is grounded, and the relative ground voltage is only 110V, improving electrical safety.

Anti theft and anti damage: The coil of the iron core transformer is directly wound and cannot be disassembled, making it particularly suitable for unmanned scenarios such as agricultural drainage and irrigation.

Harsh environment: The protection level can reach IP20 or higher, suitable for high humidity, salt spray, and dust environments (such as industrial and mining enterprises).

4. Significant economic and social benefits

Fast investment recovery: Rural power grid renovation cases show that the line loss rate has decreased from 31% to 11%, and the investment can be recovered in 5-6 years.

Environmentally friendly and low-noise: The operating noise is only 30-40 decibels (about 50-60 decibels for traditional transformers), reducing urban noise pollution.

Promoting the development of rural electricity: Low voltage loss and stable power supply improve the quality of rural electricity and assist in rural revitalization.

5. Advantages of special application scenarios

(1) Industrial control (such as BK series)

Input 220V/380V, output can be customized (such as 30V, 110V), suitable for machine tools, rectification equipment, etc. Strong overload capacity (maintaining 2 times the rated current for 1 minute), suitable for motor starting shock.

(2) New Energy and Rail Transit

As an isolation transformer in photovoltaic and wind power systems, it improves power supply stability. It can also be used as an auxiliary power supply for subways, meeting the requirements of fire prevention and low noise.

● Projects To Upgrade Rural Power Grids
Low load rate (usually 10-40%), significant energy-saving benefits.
● Urban Power Distribution Network
Residential communities, commercial centers, and other places with high requirements for power supply quality.
● Renewable Energy Projects
Intermittent energy access systems such as wind and solar power.
● Industrial Power Distribution System
Large factories and enterprises that are sensitive to operating costs.

The main parts of a 100 kva single phase transformer are the windings, core, and insulation. The windings should have low resistance and are usually made of copper, sometimes aluminum. They are wound around the core and must be insulated from it.

A100 kva single phase transformer is suitable for agricutural production, ighting & power consumption in rural power grid andremole mountalinous areas.t can aiso be used for urban power grid transfomation, wilhave good energy*saving elfect. The transformer can be installed direclyon the plaorm, or installed on the wire pole, Single-phase ol immersed distribution transfomer produced by our company has passed typetest by the nationalqualty supervision and inspection center of transformer

Baoding Yuanchen Transformer (founded in 1999) has been deeply involved in the industry for more than 20 years, covering an area of ​​98,000 square meters (26,800 square meters of building). It has the ability to carry out the entire chain of R&D, production and service. It mainly sells nearly 100 products in 6 categories, including oil-immersed transformers and dry-type transformers, with an annual output of 5 million KVA. In 2020, it obtained ISO 9001/14001/45001 three-system certification. It is a high-tech enterprise (awarded in 2016, reviewed on 19/22), a 2022 specialized and innovative small and medium-sized enterprise, and its oil-immersed transformer was selected into the energy-saving recommendation catalog of the Ministry of Industry and Information Technology in 2022.
