9581 inlet wire auto-put-into device of reserve-source

9581 inlet wire auto-put-into device of reserve-source

The 9581 inlet wire auto-put-into device of reserve-source . Mainly used to 35KV、10KV、6KV and the below voltage of the protection measuring and control of the spare line.The protection device has more than ten kinds of protection functions and also has a complete and powerful collection function of the voltage current analog quantity and switch quantity of a device;and optional standard RS485、CAN port or no communication port that can be freely to choose the anti-jump function. to avoid the collision between the microcomputer protection device and the switch;

     05. Over load           (Alarm / trip)
     06.  Zero sequence current instantaneous trip    (Trip)
     07. Zero sequence time delay  current instantaneous trip   (Trip)
     08.Zero-Sequence definite time over-current     (trip)
     09. Zero current Ⅲ Inverse time limit   (General / very / extreme
     10. Zero sequence time delay  current instantaneous trip   (Alarm / trip)
     12. Mode 1 self recovery
     13. loss of close circuit and trip circuit      (alarm)
     Description: in the conditions, the protection function can be increased to meet the needs of the field.
 
remote control function:
     01.Measuring current:Ia、Ic;
     02. Bus voltage:U1、U2;
     03. frequency:f;
 
control function:
     01.close or break of Circuit breaker
     02. close or break of main inlet
     03.close or break of spare inlet wire
 
 auxiliary function:
     01. Operation instruction:When the device is running normally,“ok "indicator light flashes regularly;
     02. Power instruction:When the device is operating normally, the "power" indicator light is always on;
     03. Device troubling: self check error, blocking relay out;
     04.Device alarm: current, the voltage reaches the set value and remains to the set time;
     05.Device trip: the current, the voltage to reach the set trip value and keep to the set time;
     06. Close or break instruction:the instruction of switch 
     07. Event records: can record 32 events, 32 remote events, 8 self test events;
     08. Online modification:“Protection and retreat”Protection fixed value"Modify can be directly modified by computer communications to save;
   09.On line printing: any interface in the protection menu that can be printed directly through computer communication;
   10 communication function: with 485 communication mode.
 
 
Protective action principle
      protection for current instantaneous trip,protection for current instantaneous trip, over current and Inverse time over-current, over load, Zero sequence time delay  current instantaneous trip , Zero sequence time delay current instantaneous trip instantaneous trip current, Zero-Sequence definite time over-current , control circuit disconnection principle is the same as with 9511 line protection

1).auto-put-into device of reserve-source equipment function
2)Charging condition(Meet the charging conditions, after 15 seconds, in the liquid crystal display charging complete symbol:
     ①Any phase measuring current(Ia、Ic)≧Line threshold valueIdz5;——Such as the  way"1  check the line current", the need for this condition.    
     ②1#inlet wire voltage U1 ≧Line pressure threshold value Udz1; 
     ③1# Switch detected close signal and no break signal(C4is 1,represent1#switch close;C5means 0,that is 1#Switch without break signal);
     ④2# Switch not detected close signal(C6means 0,represent 2#switch break);
     ⑤2#inlet wirevoltageU2≧Line pressure threshold valueUdz1;— such as ‘in service“Way 1 check inlet wire voltage”,Need this condition.
 
2).auto-put-into device of reserve-source equipment function Action condition:
     ①Measuring current(Ia、Ic)All less than no current Set value;
     ②1#inlet wirevoltageU1Less than the line pressure threshold value Udz0;
     ③2#inlet wirevoltageU2≧Line pressure threshold value Udz1; ——such as in service“Way 1 wire voltage inlet inspection, the need for this condition.
     ④1#inlet wire close(C4=1;C5=0),2#inlet wire break(C6=0);
     To meet the above conditions,auto-put-into device of reserve-source equipment function Mode 1 start,The waiting time of default close and break are 5S.close Waiting time can be set,See fixed value menu,If the corresponding points are not detected in the 5S close signal,Then prompt auto-put-into device of reserve-source equipment function Mode 1 failed.  
 
3).auto-put-into device of reserve-source equipment function Action condition:
     drive1J(B7/B8(or B6/B7)terminal)-trip1#line(main inlet wire);
     Drive 4J(B12-B13terminal)-close2#inlet wire(spare inlet wire)。
 
4).Self recovery condition:
     ①C4is 0,That is detected1#inlet wire no close signal;
     ②C5shows 1,That is detected1#inlet wire break signal;
     ③C6shows1,That is detected2#inlet wire close signal;
     ④1#inlet wirevoltageUx1≧Line pressure threshold value Udz1;
 
     To meet the above conditions, since the recovery started, the default close and break Waiting times are 5S (close waiting time can be set, see the set value menu), if the 5S does not detect the corresponding sub close signal, then prompted bus transfer equipment function Automatic way 1 failed.
