Power
电源指示灯
/Power power indicator lamp
备注
/Note
:控制器电流、时间的调整必须由专业技术人员负责
/Adjustments to the current and time of controller
should be operated by professional technicians
!
b)
控制器控制面板各部分功能
/Function of each component of control panel on the controller
(1)
测试端口
/Test port
即“
TEST
”端口,
NDM5E
专用测试仪通过该端口与控制器相连,进行测试及调试等操作
/
“
TEST
”
port, by
which special tester for NDM5E is connected to the controller to test and adjust
。
(2)
电流、时间调节旋钮
/Current, time adjustment knobs
可通过电流、时间旋钮的调节,选择适当的组合以达到保护线路、保护设备的作用。此项操作应由专业技术
人员负责
/Current and time adjustment knobs could be adjusted to select proper combination in order to protect circuit
and appliance. This operation should be operated by professional technicians
。
注
/Note
:
Tr
表示当实际电流为
Ir
整定值的
2
倍时,断路器动作时间
/Tr is the action time of breaker when actual
current is double the Ir setting value
。
如:当
Ir
整定为
1.0
、
Tr
整定为
10s
时,当主回路电流为
2
×
160A
时,断路器将持续
10s
时后断
开主回路。动作时间精度为±
10%/Fore example: When Ir setting is 1.0, Tr is 10s and current or main loop is 2X160A,
the breaker would break the main loop down after 10s. The precision degree of action time is
±
10%.
。
在过载电流下,断路器断开主回路的时间遵循以下公式
/Time for the breaker to break main loop down in
overcurrent condition is as follows
:
t=(2*Ir/I)2*Tr
I
——表示过载情况下,主回路实际电流值
/I is the actual current value of main loop in overcurrent condition
。
c)
指示灯
/Indicator lamp
(1)
预报警指示灯
/Pre-alarm indicator lamp
预报警指示灯闪亮时,表示实际电流超过了预报警电流
Ip
的整定值,经一特定时间后黄灯将由闪亮转为恒
量
/If pre-alarm indicator lamp twinkles, actual current surpasses the setting value of pre-alarm current Ip; after a while,
yellow lamp would turn to lighting from twinkling.
。
(2)
过载指示灯
/Overload indicator lamp
过载指示灯恒亮时,表示实际电流超过了过载长延时整定电流值
IR
的
1.15
倍,处于过载状态,并经一定的
时间后断路器将断开
/If overload indicator lamp keeps lighting, actual current is 1.15 times the overload long delay
setting current value; it is overload state; the breaker would break down after a while.
(3)
电源指示灯
/Power indicator lamp
控制器处于工作状态时指示灯闪亮
/Indicator lamp twinkles when controller is in working state
。
