What are the types of fire emergency power supply? How to wiring emergency lighting lamps? Photo and text

Posted on June 1, 2022 by ArticleManager

EPS emergency power supply has played an irreplaceable role in the field of fire emergency power supply and industrial reserve power supply. Whether the design of the solution brought by the diversified load is always troubled by the personnel and electrical in charge of the owner’s unit and the design institute.

Fire emergency lighting EPS emergency power supply is suitable for public places such as construction, high -speed rail, subway, highway, etc. In public places such as fire, earthquake, typhoon and other accidents, providing emergency power supply in fire emergency lights such as emergency lighting and escape routes in public places. The responsibility for the safety of life is important; it belongs to the mandatory inspection and certification management of the national fire management department. Each model must obtain the inspection and recognition certificate of the relevant national departments, and it must not change the function, structure, shape, component brand brand of the product at will , Battery configuration and other parameters.

1. Types of emergency power supply

(1)

Generation units independent of normal power supply: including emergency gas turbine generator sets and emergency diesel generator sets. The fast -starting generator set is suitable for allowing the power supply to interrupt the power supply time above 15s.

(2) UPS uninterrupted power supply: It is suitable for the load that allows interrupting the power supply time to be in milliseconds.

(3) EPS emergency power supply: an emergency power supply that inverts the battery’s DC power into AC power. It is suitable for allowing loads with an interrupt power supply of 0.25s or more. It’s easier than UPS.

(4) There is an automatic input device: a special feed line that is effectively independent of normal power supply. Applicable to load that allows interrupt power supply time of 1.5s or 0.6s.

(5) Battery: It is suitable for a particularly important load with a small capacity, and it is possible to use a DC power supply.

Second, emergency power system

(1) In engineering design, the particularly important load proposed by other majors should be studied carefully and minimized the load volume of the particularly important load as much as possible, except for those with double security measures.

(2) In order to ensure power supply to particularly important loads, other loads are strictly prohibited to connect to the emergency power supply system.

(3) Reliable measures must be taken between the emergency power supply and normal power supply. The purpose is to ensure the exclusiveness of the emergency power supply, and more importantly is to prevent counterfeiting to the system.

(4) The two -back power lines of disaster prevention or similar electricity equipment should be automatically switched at the last level power distribution box. Large -scale enterprises and important civil buildings often use several emergency power supply at the same time, which should make various emergency power supply equipment closely cooperate and give full play to their role. Examples of emergency power system wiring (using batteries, uninterrupted power supply devices, and diesel generators at the same time as examples) are shown in Figure 2-5.
