Mid-Autumn is a letter written by Chinese people to reunion. In the letter there is the moon, there are mooncakes, there is the journey home, and there is also a house of lights that never goes out.
We are used to the light coming on when we press the switch. But behind the ever-bright lights, there are two silent guardians in the power distribution system: ATS Und Leistungsschalter.
The Mid-Autumn Holiday Makes Power Loads More Concentrated
As schools, factories, offices and other places take holidays, electricity demand shifts between different places. In places that remain open during the festival, such as shopping malls, restaurants and hotels, increased customer flow pushes up the load of air conditioning, lighting and elevators.
The concentration of electricity consumption makes the carrying capacity of local lines, and the issue of rapid switching during faults more prominent. This is exactly where automatic power transfer switch Und electrical circuit breakers prove their value: circuit breakers prevent local overloads and short circuits from developing into accidents, while ATS transfers important loads to backup power when the main power supply is abnormal, so that the holiday does not fall into darkness because of a single fault.
Which Equipment Needs to Continue Running After a Power Outage?
Before the festival, you can first list the equipment that still needs to run after a power outage.
At home, you can focus on checking lighting, refrigerators, network equipment and other equipment that needs continuous power supply.
Restaurants can focus on refrigerators, necessary lighting, cash registers and equipment that needs continuous operation.
Hotels can focus on checking necessary lighting in guest rooms and public areas, refrigeration equipment, security equipment and other equipment that needs continuous operation.
Shopping malls can confirm in advance the power supply arrangements for lighting, air conditioning and other key equipment in business areas.
Backup power does not need to cover all equipment. The power supply system divides different lines according to the importance of the equipment, and connects the equipment that needs continuous operation to the corresponding backup power supply.
This arrangement also makes it convenient to check the capacity of the backup power supply and the condition of the line connections.
How Do PV and Backup Power Participate in Holiday Power Supply?
A PV system generates direct current through solar modules, and an inverter converts the direct current into alternating current for AC loads.
If the system is also configured with the grid, solar, energy storage or a generator, it is necessary to check the connection methods and switching equipment between the power sources before the festival.
For systems configured with automatic switching, ATS can switch between normal power and backup power according to set conditions.
If the backup power is provided by a generator, users need to check the generator’s fuel, battery, starting and output status in advance.
If the backup power is provided by an energy storage system, users need to check the status of the energy storage equipment and the connection of the backup lines.
Which Electrical Equipment Should Be Checked Before the Mid-Autumn Festival?
The pre-festival check does not need to be very complicated. Users can check item by item according to the equipment actually used.
- Check Newly Added Electrical Equipment
Confirm that the power cords, plugs and connection positions of decorative lights, light strips, temporary equipment and newly added appliances are normal.
- Check Commonly Used Sockets
Check whether sockets and plugs are damaged, loose, discolored or obviously hot.
- Check Circuit Breakers
Check the appearance of circuit breakers and the wiring positions. If abnormal heating, discoloration or frequent tripping is found, the cause needs to be found first.
- Check Backup Power
Confirm that the generator, energy storage equipment or other backup power is in usable condition, and check the related connecting lines.
- Check Automatic Power Transfer Switch
For systems using ATS switch, it is necessary to check the main power supply, backup power supply, load wiring and equipment status indications. Automatic switching systems also need to check the switching function according to equipment requirements.
- Confirm Important Loads
List the lighting, refrigeration, security, communication and other equipment that still needs to run after a power outage, and confirm that these devices have been connected to the corresponding power supply lines.
- Clean the Environment Around Electrical Equipment
Keep distribution boxes, mcb breakers and other electrical equipment dry and tidy, and avoid debris affecting the normal use of the equipment.
