The emergency Dongguan generator rental is
mainly used in important places. When an emergency power outage or emergency occurs, the emergency generator set can quickly recover and extend the power supply period. This type of electrical load is called a primary load. Communication equipment, meters, and computer systems that have strict requirements on the power outage time should be powered by a battery or UPS in addition to the generator set.
There are two characteristics of emergency Dongguan generator rental
work. The first feature is for emergency use, and the continuous working time is not long. Generally, it only needs to run for a few hours (≤12h). The second feature is for backup, and the emergency generator set is usually used. It is in a waiting state for shutdown. Only when the main power supply fails and fails, the emergency generator set starts to supply the emergency power load. When the main power supply returns to normal, it will be switched off immediately.
Determining the capacity of emergency diesel generating units The calibrated capacity of emergency diesel generating units is a 12h calibrated capacity corrected by the environment (elevation, altitude, ambient temperature, air humidity, etc.), and its capacity should be able to meet the total calculated load of emergency power, and it should The capacity can be verified to meet the requirements for starting a single maximum-capacity motor in a first-level load. Emergency generators generally use three-phase AC synchronous generators with a nominal output voltage of 400V.
Determining the number of emergency generator rental units When there are multiple generator sets in standby, generally only one emergency diesel generator set is provided. For reliability considerations, two units can also be selected to run in parallel to supply power. Generally, the number of generator sets for emergency use should not exceed three. When multiple diesel generators are selected, the unit should try to use complete sets of equipment with the same model and capacity, similar pressure and speed characteristics, and the nature of the fuel used should be the same for operation and maintenance and shared spare parts.
When two generators for emergency use are leased, the self-starting device should enable the two units to be used as backups for each other, that is, after the delay of the mains power failure is confirmed, a self-starting command is issued. If the first unit is 3 consecutive times Since the self-starting fails, an alarm signal should be issued and the second unit should be started automatically. http://ftfan.cn/
