Advantages and applications of backup power supply in shopping malls

The shopping mall is a public place, and the flow of people is also very large. Some elevators and stores of electricity failure will cause a lot of 

inconvenience to the mall.

What is the store backup power automatic input device?

When the shopping mall encounters a power failure, after the working power supply is disconnected, the standby power supply can be automatically 

and quickly put into work, which can ensure the normal operation of the shopping mall.

The classification of the primary wiring of the standby power supply device in the shopping mall. 

Open standby power: the shopping mall power supply is obviously disconnected in normal times, and a dedicated shopping mall standby power 

supply is installed.

Dark backup power: the mall power supply is not obviously disconnected from the government backup power supply in normal times, and the 

segmented bus bars are used to alternate with each other.

The advantages of a standby power supply.

Install a standby power supply in the mall so that when the mall is out of service, you can improve the reliability of the power supply, save on the 

construction investment, and simplify the continued power protection. The store's backup power supply can also limit the short-circuit current, which 

can increase the residual voltage of the bus.

The application of backup power supplies in shopping malls.

A store is equipped with a backup power supply, which is powered by two power supplies and can be used as a backup when one of the power 

supplies is frequently disconnected. It is also possible to reduce the pressure of the substation in the spare transformer and some spare units of the 

laying machine.

All in all, once a power failure occurs in the shopping mall, it will not only cause serious losses to the mall but also cause harm to the safety of 

personnel. It is necessary to install backup power supplies in shopping malls.
