EPS消防应急电源该如何选择？选型原则是什么？

EPS emergency power supply, how to choose? Selection What are the principles?

一、直流电源柜厂家负载容量选型原则:

因电动机的启动冲击，与其配用的集中应急电源容量按以下容量选配。

1、电动机变频启动时，应急电源容量可按电动机容量1.2倍选项配。

2、电动机软启动时，应急电源容量应不小于电动机容量的2.5倍。

3、电动机Y-△启动时，应急电源应不小于电动机容量的3倍。

4、电动机直接启动时,应急电源容量应不小于电动机容量的5倍。

5、混合负载中,大电机的容量若小于总负载容量的1/7.

A load capacity of the principle of selection:

Due to the impact of motor starting, its equipped with a centralized emergency power capacity in the following capacity matching.

1, the motor frequency starts, emergency power supply capacity can be 1.2 times the option with the motor capacity.

2, motor soft start, the emergency power supply capacity should be not less than 2.5 times the motor capacity.

3, the motor Y-△ start, the emergency power supply should not be less than three times the motor capacity.

4, motor direct start-up, emergency power supply capacity should be not less than five times the capacity of the motor.

5, the mixed load, the maximum capacity of the motor is smaller than if the total load capacity of 1/7.

二、选型容量计算方法:

1、柏克YJ系列或YJS系列用于带应急灯具负载时：

（1）当负载为电子镇流器日光灯，EPS容量计算方法：EPS容量=电子镇流器日光灯功率和×1.1倍。

（2）当负载为电感镇流器日光灯，EPS容量计算方法：EPS容量=电感镇流器日光灯功率和×1.5倍。

（3）当负载为金属卤化物灯或金属钠灯，EPS容量计算方法：EPS容量=金属卤化物灯或金属钠灯功率和×1.6倍。

Second, the selection of capacity calculation method:

1, Burke YJ series or YJS series used with emergency lighting load:

(1) When the load is electronic ballast fluorescent, EPS capacity calculation method: EPS capacity = electronic ballast fluorescent lamp power and × 1.1-fold.

(2) When the load is inductive ballast fluorescent, EPS capacity calculation method: EPS capacity = inductive ballast fluorescent lamp power and × 1.5-fold.

(3) When the load is a metal halide lamp or a metal sodium, EPS capacity calculation method: EPS capacity = sodium metal or a metal halide lamp power and × 1.6 times.

2、当YJS系列用于带混合负载时,EPS容量的计算方法:

（1）当EPS带多台电动机且都同时启动时,则EPS的容量应遵循如下原则：

EPS容量=变频启动电动机功率之和+软启动电动机功率之和×2.5+星三角启动机功率之和×3+直接启动电动机之和×5倍

2, when the YJS series is used with mixed loads, EPS capacity calculation method:

(1) When the EPS with multiple motors and are simultaneously activated, then the capacity of the EPS should follow the following principles:

EPS capacity = frequency start the motor power and + soft start motor power of × 2.5 + star delta starter motor and the power of the motor is started directly × 3 + and × 5 times the

（2）当EPS带多台电动机且都分别单台启动时(不是同时启动),则EPS的容量应遵循如下原则：

EPS容量=各个电动机功率之和,但必须满足以下条件：

※ 上述电动机中直接启动的大的单台电动机功率是EPS容量的1/7.

※ 星三角启动的大的单台电动机功率是EPS容量的1/4.

※ 软启动的大的单台电动机功率是EPS容量的1/3.

※ 变频启动的大的单台电动功率不大于EPS的容量.

※ 如果不满足上述条件,则应按上述条件中的大数调整EPS的容量,电动机启动时的顺序为直接启动在先,其次是星三角的启动,有软启动的再启动,后是变频启动的再启动.

(2) When more than one motor and belt EPS were all single boot (not simultaneously start), then the capacity of the EPS should follow the following principles:

EPS capacity = sum of all motor power, but must meet the following conditions:

※ The motor started directly largest single motor power is the EPS capacity of 1/7.

※ star delta starter largest single motor power is the EPS capacity of 1/4.

Soft start ※ largest single motor power is the EPS capacity of 1/3.

※ inverter startup largest single electric power less than EPS capacity.

※ If not the above conditions shall be the maximum number of the above conditions the capacity to adjust the EPS, the motor startup sequence is started directly first, followed by the star-delta start-up, a soft start re-start, and finally the frequency conversion re-start.

（3）当YJS系列EPS带混合负载时EPS应遵循如下原则：

EPS容量=所有负载总功率之和,但必须中以下六条件,若不满足,再按照其中大的容量确定EPS容量.

※ 负载中直接同时启动的电动机功率之和是EPS容量的1/7

※ 负载中星三角同时启动电动机功率之和是EPS容量的1/4

※ 负载中软启动同时启动的电动机功率之和是EPS容量的1/3

※ 负载中变频启动同时启动电动机功率之和不大于EPS的容量.

※ 同时启动的电动机当量功率之和不大于EPS的容量.

电动机功率容量=直接启动的电动机总功率x5+星三角同时启动的电动机总功率x3+软启动同时启动的电动机总功率x2.5+变频启动且同时启动的电动机总功率

若电动机前后启动时间相差大于1分钟均不视为同时启动。

※ 同时启动的所有负载(含非电动机负载)的当量功率之和不大于EPS的容量。

同时启动的所有负载的功率之和=同时启动的非电动机总功率×功率因数+电动机当量总功率。

(3) When the YJS series EPS EPS with mixed loads should follow the following principles:

EPS capacity = total power of all loads, but it must in the following six conditions, if not met, then the capacity determined in accordance with one of the largest EPS capacity.

※ load directly activated simultaneously and that the EPS motor power capacity of 1/7

※ star delta load and start the motor power and is EPS capacity of 1/4

※ load soft start motor power of simultaneously started and is EPS capacity of 1/3

※ load and start motor power inverter startup and not greater than the capacity of the EPS.

※ started simultaneously equivalent power of the motor is not greater than the capacity of EPS.

Motor power capacity = direct start of motor power x5 + star delta start simultaneously x3 + motor power soft-start and start the motor power x2.5 + inverter motor starts and the total power simultaneously started

If the motor before start time difference than 1 minute are not regarded as the same time.

※ started simultaneously all loads (including non-motor loads) of equivalent power is not greater than the capacity of EPS.

Started simultaneously in all the power load and simultaneously start = total power × non-motor motor power factor + Equivalent total power.
