Utility

In the field of public services (such as electricity, water, gas, etc.), transformers are core equipment to ensure the stable operation of infrastructure.

Power industry

Application scenarios: power generation, transmission, distribution, renewable energy grid connection, etc.

Solutions:

- High-voltage transmission: Use large-capacity power transformers to achieve long-distance and efficient power transmission and reduce losses.

- Distribution network: Equipped with intelligent distribution transformers, support automatic control, and achieve dynamic load adjustment.

- Renewable energy integration: Special transformers (such as double-winding or three-winding transformers) smoothly connect intermittent energy such as wind power and photovoltaics to the grid.

Grid stability: Equipped with on-load tap-changing transformers to adjust voltage fluctuations in real time to cope with peak and valley load differences.

- Fault protection: Integrated relay protection system, with circuit breakers to quickly isolate fault areas and prevent power outages from spreading.

Technological innovation:

- Smart transformer: Built-in sensors to monitor temperature, vibration, oil level and other parameters in real time, combined with AI predictive maintenance.

- Environmentally friendly design: Use vegetable oil insulation or low-noise transformers to reduce fire risks and noise pollution (such as residential substations).

Water industry

Application scenarios: water treatment plants, pumping stations, water supply network monitoring, etc.

Solutions:

- Pumping station power supply: Use high-efficiency dry-type transformers (such as epoxy resin cast type), which are moisture-proof and corrosion-resistant and adaptable to humid environments.

- Emergency power supply: Configure redundant transformers + UPS/diesel generators to ensure that the pumping station continues to operate during power outages and avoid water supply interruptions.

- Remote monitoring: The transformer is linked to the SCADA system to monitor the power status of water quality treatment equipment in real time.

- Energy-saving optimization: The variable frequency drive is combined with the transformer to adjust the speed of the water pump motor and reduce energy consumption.

Special requirements:

- Explosion-proof design: Explosion-proof transformers are used for hazardous areas such as chlorine treatment.

- Redundant configuration: N+1 backup solution to ensure power supply for key water treatment links.

Gas Industry

Application scenarios: gas booster stations, gas pipeline monitoring, LNG plants, etc.

Solutions:

- Explosion-proof safety: Use explosion-proof transformers in flammable and explosive environments.

- Stable power supply: Provide uninterruptible power supply for SCADA systems and remote valve control.

- Energy efficiency management: High-efficiency oil-immersed transformers reduce the operating energy consumption of gas compressors.

- Extreme environment adaptation: Customized low-temperature resistant transformers for northern gas pipelines or LNG facilities.

Technological innovation:

- Digital monitoring: Analyze transformer data through edge computing, warn of potential faults, and avoid gas leakage risks.

- Compact design: The box-type substation integrates transformers and power distribution equipment to save space in the gas booster station.

Cross-industry universal solutions

Core requirements: reliability, safety, energy efficiency, and intelligence.

- Redundancy and backup: Dual power input + automatic switching device to ensure power supply to key facilities (such as hospitals and data centers).

- Disaster prevention design: earthquake-proof base and waterproof shell to cope with disasters such as floods and earthquakes.

- Green transformation: Use amorphous alloy transformers to help achieve the "dual carbon" goal.

- Intelligent operation and maintenance: Digital twin technology simulates transformer status, optimizes maintenance cycles, and reduces manual inspection costs.

Future trends

- Solid-state transformers: Replace traditional electromagnetic transformers, achieve high-frequency voltage conversion and bidirectional energy flow, and support DC microgrids.

- Hydrogen energy compatibility: Provide high-power density transformers for hydrogen electrolyzers and fuel cell facilities.

- Modular design: Plug-and-play transformer units for rapid deployment in emergency scenarios.

Through customized design and intelligent upgrades, transformers will continue to improve the resilience, energy efficiency and service quality of infrastructure in the public service field, and help achieve smart cities and sustainable development goals.
