Information

When industrial production and public buildings are in a state of emergency for safety accidents, it is very convenient to ensure the success of firefighting in safety accidents. The external switching power supply responsible for the power supply of the safety fire-fighting power consumption mechanical equipment and the distribution system is called emergency backup power supply. The following will introduce you to the types of emergency backup power supply.

Types of emergency backup power supply:

1. EPS emergency backup power supply: It is a kind of emergency backup power supply, which is composed of charging plug, variable frequency power supply, storage battery, DC protection transformer, instrument, transfer switch and other mechanical equipment, which converts AC current energy inverter power supply into AC power supply. It can be used to interrupt the power supply and power distribution system of the load exceeding 0.25s.

2. UPS power supply: It is mainly composed of on-site fixed AC and power engineering converter energy storage mechanical equipment (battery) and power main switch (electronic components and machinery) to ensure the continuity of the power supply and power distribution system. It can be used to allow interruption of the power supply and the load of the power distribution system in milliseconds.

3. Reserve emergency diesel engine Reserve diesel generator set: It uses diesel engine as the power to drive the generator set machine composed of DC and AC power and communication induction motor emergency backup power supply equipment. Quick-start diesel generator sets can be used in construction projects that allow the power supply and distribution system to be interrupted for more than 15 seconds. During the production process, the working time of the emergency power supply should be fully considered according to the allowable power-off time. When used with an auto-start diesel generator set, it should be no less than 10 minutes.

4. Emergency backup power supply: It has a dedicated explosion-proof switch circuit, which has nothing to do with all the ordinary power transformers used for automatic fund distribution machinery and equipment. The placement time of the available self-input machines can take into account the emergency power supply, which can interrupt the power supply and the power distribution system within 1.5s or more than 0.6s. For those who are allowed to turn off the power supply within ms level and the capacity is not too large for very important loads, if a DC regulated power supply can be used, the battery pack should be used as a battery.

5. Reserve an emergency gas turbine diesel generator set; it uses a gas turbine as a driving force and drives a generator set consisting of DC and AC power and communication induction motors. Emergency backup power supply equipment.
