三、主要功能main function
1、失压计时under voltage time record
当电压回路(pt)发生失压时,能及时准确判断故障的相别,记录其故障期间的累计时间。若有外部有电能脉冲输入,则可同时记录故障期间的非正常电能量。
when undervoltage occurs to voltage circuit (pt), able to determine the accurate phase of fault, record the cumulative time of failure period. if external has active power input, can also record abnormal electrical energy during failure period at the same time.
2、断流计时break current time record
当电流互感器二次侧(ct)开路时,能及时准确判断故障的相别,记录其故障期间的累计时间。若有外部有电能脉冲输入,则可同时记录故障期间的非正常电能量。
when the current transformer secondary side (ct) open, able to determine the accurate phase of fault, record the cumulative time of failure period. if external has active power input, can also record abnormal electrical energy during failure period at the same time.
3、故障电量纪录power failure records
当仪表有计量脉冲输入时,能准确分相计量故障电能,从而得到比较精确的电量追补。
when the instrument has external active power input, able to measure and record accurate fault electrical energy of each phase, to get electricity reclaiming more accurate.
4、故障次数纪录number of failures records
当电压回路(pt)发生失压,电流回路(ct)发生开路时,仪表内部启动故障次数计数器,记录失压次数或断流次数。它是一个辅助参量。
when undervoltage occurs to voltage circuit (pt), or current circuit (ct) open, instrument will start counter of failure times, to record times of under voltage and break current. it is an auxiliary parameter.
5、事件纪录event record
本仪表能按事件发生先后顺序实时记录失压、断流的起始日期、起始时间、终止日期、终止时间。事件纪录多达100项。
the instrument can record in time sequence of events of undervoltage and break current, include start and end date, start and end time. able to record up to 100 events.
6、数据通讯data communication
对于有通讯功能的仪表,通过仪表rs485通讯辅助接线端子,可与通讯终端或上位机进行数据通讯,在无中继设备的情况下通讯距离小于1200m。(此功能用户提供通讯规约,并在订货前加以说明)。
instrument which has communication function, is through rs485 communication auxiliary wiring terminal, able to achieve data communicate with communication terminal or upper computer, communication distance less than 1200m under non trunking circumstance. (customer provide communication agreement, and state in contract.)
7、数据查询data check
仪表正常工作时,可通过控制按钮或遥控器查询某页内容或某项内容。
while instrument working normally, able to check any page or any content through control button or remote control
8、参数设置parameter settings
通过编程器可对表号、脉冲常数(100-99900)、通讯波特率(1200-9600)、循环显示时间间隔(1-99秒)、日期(当前日期)、时间(当前时间)进行设置。
through programmer able to setting of meter number, pulse content (100-99900), communication baud rate (1200-9600), cycling display time interval (1-99 seconds), date (current date),and time (current time).
9、报警输出alarm output
当仪表处于失压、断流状态时,可通过蜂鸣器或外界大功率报警装置进行报警。仪表出现报警后,可通过按下仪表“上行”或“下行”按钮或遥控器复位按钮进行关闭。关闭报警输出,不会影响仪表的数据记录。
when the instrument is under voltage, or break current state, is able to alarm through buzzer alarm device or an external high-power alarm device.
press "upward" and "down" button on instrument to turn on or off of alarm output.
open or close the alarm output will not affect the instrument's data records.
