Function: realize the automatic switching of two power sources, including municipal power supply and utility power supply, between municipal power supply and power generation or between power generation, so as to ensure the normal power consumption requirements of users. Voltage range: (400VAC / 50Hz capacity range: 63a-6300a safety measures: fully automatic operation, mechanical and electrical double interlock. Shopping malls, hotels, and factories have strict requirements for power interruption time, so they should use the city / generator automatic switching system. This system can automatically switch to the backup power supply system within a short time after the original power supply system is cut off, so as to maintain the normal power supply.
working principle
If the original supply system is mains power, when the mains power is cut off or the three-phase power shortage is equal, the automatic switching system will immediately cut off the municipal power supply and start the generator automatically. After the generator starts running, the power will be sent out in 3 seconds. When the mains power supply is normal, the generator will be stopped for 30 seconds, and the power supply will be automatically switched to the mains power supply.
If the original supply system is a generator, the automatic switching system will immediately cut off the power supply of the generator and automatically switch to the municipal power supply when the power generation opportunity fails to stop.
Main functions:
1. The main circuit adopts well-known ATS type circuit breaker for electrical and mechanical interlocking respectively. It is equipped with electric closing motor, manual closing and other accessories. It can only ensure that one power supply is connected to the load, and the working performance is safe and reliable, and durable.
2. The auxiliary circuit adopts reliable time relay, intermediate relay and other advanced auxiliary circuit functions, and the working order runs stably. It has automatic and manual flexible application.
3. It has the functions of time delay of utility recovery function, confirmation delay of mains power failure, static zone delay of switch conversion, load delay of generator set and cooling delay of generator set.
4. This series of products can be used with any brand of remote start automation unit, can control the automatic start and stop of the generator, automatically switch power supply, so as to achieve the function of automatic protection of power supply system stability, which can be described as the most ideal distribution product.
