The uninterrupted power supply (UPS) provides emergency power in case of power failure or for some reason will turn off the main power supply. Different from the emergency power system , which requires time to activate, as soon as triggered during an accident. If you can’t afford the losses of power during the project – for example, for all – day boot- UPS is the best solution to protect yourself against data loss and prevent interference in the system. Because something is called infinite, because that will completely eliminate simple.
There are three main types of uninterrupted power supply, namely, on-line, line-interactive and standby. Works online UPS accepts AC input (AC) converts the direct current (DC) to download it through the battery, and then converts it back to AC to power the protective equipment. Line-interactive UPS redirects you to the path of sustained battery current from a charge mode to power mode during power failures. This is a very intuitive machine that could hold reserves of power at a continuous voltage drop or przepięciasytuacje by choosing the optimal amount of backup power to the power source. System backup (also called system off-line) is powered directly via a standard AC electrical outlet only provides emergency power in case of outage of the primary power source. Standby UPS is the simplest and most popular type of personal computer offers basic features such as surge protection and battery backup.
In the case of especially large needs of the power corresponding to the dynamic UPS. A model of dynamic use of a synchronous generator, which is connected to the main unit via a throttle. The device stores energy in the flywheel, and idle time current regulator keeps the power of the vortex. Lately, experts have developed a UPS powered by fuel cells, which is more environmentally friendly and quieter. Uses the hydrogen and fuel cells as a power source and is ideal for small areas.
The most common causes of interruptions in the power
There are several reasons why the power comes from human error to natural disasters. During a severe storm a tree might fall on a power line, breaking it and cutting off the current from the whole district or city. If you live in an area with extreme weather conditions, always allow consumers the city complied with the order of work in your backyard – they’re doing it for your safety, and probably removing shrubs that are too close to power lines. If the storm does not cause the fall of a tree, he can send the lightning to power lines or cause a flood that will damage the device above or under the ground .
If you live in an area with high activity of wildlife, the UPS can be invaluable. The animal can crawl on the transformer or fuse, resulting in automatic shutdown to protect the rest of the system, which makes you powerless. If you live in a remote location, you can be at a distance of a few tens of miles from the building with food, so you will have to provide themselves.
The construction work on Your property or street can lead to a crash diet. Employees can accidentally make a hole in the transmission line or to send a tractor back over one. Car zderzający with tyczką can also lead to malfunction. Learn the basic precautions in case your street a free supply line. Moreover, the UPS, you should know what to do if you cannot restore the energy within a few hours.
The biggest UPS in the world
In Fairbanks, Alaska where the temperature can fall to minus 50 degrees Celsius, power outages were a common problem. The remote nature of the state means that downtime can be very dangerous because the only way that residents can travel to another state, ship or plane. If the communication tower is disabled, the navigation, after these ships threat. In Alaska, they are people too, living in almost complete isolation, so they are almost helpless when their power will fail. People just can’t survive if the radiator burst at a negative 50-degree weather.
In August of 2010. Group processing Boverithe ASEA brown (ABB) has established the world’s largest UPS system in Fairbanks. The system consists of a transmitter, was developed by ABB, and Nickel-cadmium established by the battery manufacturer Safta. The Converter converts the DC battery current to AC current, and can produce up to 27 megawatts for 15 continuous minutes. This quarter of an hour gives the system time to the backup. The system can deliver 46 MW in a shorter time, but Fairbanks need it in the first place to transmit the energy long enough to be able to run the backup.
The UPS can operate in seven different modes, one of which is automatic scheduling that provides immediate support system, if the breaker on the transmission line or a local generator. Also has a mode of the stabilizer, the power supply system that suppresses fluctuations in the power system. In the charging mode Manager controls how fast loads megawaty UPS, and when the system can start charging again after emergency discharge.
