What Is Portable Power Supply?
A portable power supply is a facility or device that supplies electricity in the event of a power failure due to an earthquake or fire.
UPS, which protects personal computers and servers from sudden power outages, is called an uninterruptible power supply and has a slightly different meaning from portable power supply.
Portable power supply is used for equipment where a power failure would cause significant problems, such as elevators, fire sprinklers, fire shutters, and medical equipment.
Uses of Portable Power Supply
Portable power supplies are mainly used for equipment where a power failure could threaten the safety of the equipment or human life. Examples include fire sprinklers, fire shutters, smoke exhaust systems, and fire doors installed in large buildings.
If these systems were to fail due to a power outage, the damage in the event of a fire would be very great.
These portable power supplies are not always connected, but may be connected as needed, in which case the color of the outlet is changed to indicate that it is an emergency power supply.
Principle of Portable Power Supply
The simplest portable power supply are battery-powered emergency power supply. The battery type is very simple and has a simple structure, but it must be constantly charged and must be replaced periodically.
Although the recharging capacity and discharge time have been greatly improved with the advent of lithium-ion batteries, they cannot be used for equipment that requires large amounts of power.
In addition, a small generator may be installed as portable power supply. Emergency generators use city gas as fuel, so they can operate without problems as long as gas is supplied even if only electricity is lost.
In particular, some emergency generators generate not only electricity but also heat energy in the form of steam, which leads to energy savings if used on a regular basis.
However, in the event of a major disaster, the city gas supply, etc., may stop, so battery-powered emergency power sources and cogeneration systems are often installed to save energy and prepare for power outages in the event of a disaster.
Principle of Portable Power Supply
Portable power supplies for home use include lithium-ion batteries, diesel fuel generators, and gas generators. most reliable.
In many cases, gas is still supplied even when power lines are cut due to typhoon disasters or other power outages. Gas-powered generators are useful in such cases. They can produce enough electricity to power an average household for 74 hours of normal daily life. More time can be spent by saving electricity usage, and this can be of great help in times of disaster, such as heating and many products allow easy one-touch connection between propane gas and a generator.
Portable Power Supply for Hospitals
Hospitals are the most important facilities that must continue to use electricity even in the event of a power outage due to a disaster. Many medical devices, some of which are intended for people whose lives would be difficult to sustain without them, must continue to be supplied with power even in the event of an emergency.
In order to ensure that only necessary equipment is supplied with power in the event of a power outage or other emergency.
In addition to regular electrical outlets, hospitals are taking measures to prepare for emergencies by properly selecting medical equipment based on the above definitions.
