At 7:45 on July 22nd, a 6.6-magnitude earthquake occurred at the border of Ganxian and Ganxian in Dingxi City, Gansu Province. The focal depth was 20 kilometers. The earthquake did not affect the main grid of Gansu Power Grid. A 15,000-volt line switch tripped at 35 kV Shendu Substation. The 35 kV Zhongzhai Substation No. 1 main transformer switch tripped and a 10 kV line tripped. Some of the power lines in Qixian and Jixian fell down. The disaster caused a total of 190 power distribution stations to change, and 14066 users were out of power. After emergency repairs, as of 12:00 on July 22, the distribution board has recovered 105 units, and 9240 households have resumed power supply, which accounted for more than half of the total number of power outages. After the earthquake, the State Grid Gansu Electric Power Company attached great importance to the earthquake disaster, immediately launched an emergency plan, held a special meeting, set up an emergency command organization, and repaired the team on the spot, and quickly arranged related personnel to carry out earthquake relief work. As of 14:00 on July 22, a total of 151 electric power personnel were repaired, 10 generators and one generator car. It is understood that the current power emergency rescue mainly involves two tasks. First, the affected equipment is repaired and power supply is resumed as soon as possible. The second is the protection of on-site power supply for the site, medical site, and resettlement sites for victims.
The application of the transformers we produce:
1. Building Automation and Control Systems
In modern buildings, power transformers are used to supply power to building automation systems, including lighting control, HVAC (heating, ventilation, and air conditioning) systems, and security systems.
They convert the main power supply to a safe and manageable voltage level, ensuring optimal performance and reliability of these systems.
2. Industrial Control Panels and PLCs (Programmable Logic Controllers)
Industrial control panels and PLCs require precise and stable power supplies to function correctly. power transformers provide clean, filtered power to these devices, minimizing interference and ensuring accurate control.
3. Machine Tool and Automation Equipment
In manufacturing and production facilities, power transformers are used to power machine tools, automation equipment, and robotic systems.
They ensure that these devices operate at the correct voltage level, preventing damage and maximizing productivity.
4. Low-Voltage Electrical Distribution
power transformers are essential components in low-voltage electrical distribution systems, where they convert the main power supply to the required voltage level for distribution to various loads.
This includes supplying power to outlets, lighting fixtures, and other electrical devices in commercial and residential buildings.
5. Audio-Visual and Entertainment Systems
Audio-visual and entertainment systems, such as sound systems, stage lighting, and projection equipment, often require power supplies.
power transformers provide clean, stable power to these systems, ensuring optimal performance and minimizing interference.
6. Medical Equipment and Laboratories
Medical equipment and laboratories require precise and reliable power supplies to ensure accurate measurements and safe operation.
power transformers are used to supply power to various medical devices, laboratory instruments, and testing equipment.
7. Renewable Energy Systems
In renewable energy systems, such as solar and wind power plants, power transformers are used in energy conversion and distribution processes.
They help in stepping down the generated voltage to a level suitable for distribution to the grid or for use in local loads.
8. Backup Power Systems
Backup power systems, including uninterruptible power supplies (UPS) and emergency generators, often incorporate power transformers.
These transformers ensure that the backup power supply is delivered at the correct voltage level, maintaining power continuity during power outages.
In summary, power transformers are vital components in numerous applications where safe, reliable, and efficient power distribution is essential. Their ability to convert and distribute electrical energy at low voltages makes them ideal for use in building automation, industrial control, machine tools, low-voltage electrical distribution, audio-visual systems, medical equipment, renewable energy systems, and backup power solutions.
