Description

Interlocking of PT cabinet and motor cabinet:
RC527 3BSE008154R1 This interlock is mainly used for PT disconnection and voltage loss lockout. The microcomputer protection of the motor cabinet has the undervoltage protection function. As long as the primary bus is undervoltage or voltage loss, the motor cabinet should trip to protect the normal operation of the motor. However, when the 3-phase fuse of the PT cabinet is blown, or the PT air switch is manually disconnected, or the PT handcart is manually shaken out to the test position, the PT voltage circuit will be disconnected, and the microcomputer protection of the motor cabinet will also misjudge the bus voltage loss, so it will trip by mistake. Therefore, the PT disconnection voltage loss locking function must be set, so that when the fuse core needs to be replaced, or the PT handcart needs to be shaken out to the test position for relevant maintenance, the motor cabinet will not trip by mistake.

4.6.2 Interlocking operation outside RC527 3BSE008154R1 cabinet
(1) Interlocking of ABB incoming cabinet and 132KV/6.6KV transformer control and protection panel: when the current differential protection action of 132KV/6.6KV transformer control and protection panel fails, the fault signal of the control and protection panel will be transmitted to the downstream ABB incoming cabinet, and the incoming cabinet will trip immediately. At the same time, the fourth LED red indicator of the computer REF610 will light up for alarm.
(2) Interlocking of ABB motor cabinet and capacitor high-voltage reactive power local compensation device: when the power capacitor of the high-voltage reactive power local compensation device has a fault or the high-voltage fuse core is fused, a signal will be sent to the corresponding motor cabinet. The seventh LED red indicator of the motor cabinet microcomputer REX521 lights up to alarm, but to ensure the normal operation of the motor oil pump, ABB motor cabinet will not trip.
(3) Interlocking of ABB motor cabinet and motor oil pump: the motor oil pump is equipped with remote emergency button, which can make the motor cabinet emergency trip.
(4) Interlocking between ABB motor cabinet and background PLC: the background PLC is equipped with remote emergency button, which can make the motor cabinet emergency trip;
At the same time, the closing operation signal, protection trip fault signal of the motor cabinet and the fault alarm signal of the capacitor high-voltage reactive power local compensation device will be transmitted to the background PLC.
(5) Interlocking of ABB station transformer cabinet RC527 3BSE008154R1 and 6.6KV/0.4KV transformer: transformer ultra-high temperature fault tripping, transformer heavy gas fault tripping, transformer pressure release fault tripping, transformer high temperature fault alarm and transformer light gas fault alarm.
4.7 Basic operation of microcomputer protection devices REX521 and REF610
Prompt: To learn more about the operation of the microcomputer protection devices REX521 and REF610, please refer to the relevant instructions.
4.7.1 Basic operation of microcomputer protection device REF610
(1) Monitoring three-phase current measurement
Method 1: In the main menu ABB status, press the “Picture” key to display “MEASUREMENTS”, press the “Picture” key to display the measurement submenu, and press the “Picture” key to display L1, L2, L3, IO and other secondary current values.
Method 2: ABB status in the main menu, press the “Picture”+”Picture” keys at the same time, and simultaneously monitor the secondary value of L1, L2, L3 three-phase current and the secondary value of IO ground fault current.
(2) Check startup and tripping fault records
In the main menu ABB status, press the “Picture” key twice to display “RECORDED DATE”, press the “Picture” key to display the fault date submenu, press the “Picture” key respectively to display five fault records from “1EVENT” to “5EVENT”, press the “Picture” key respectively to view each detailed fault record, and press the “Picture” key respectively to display the fault time, date, starting current values, current action time, etc.
Note: The action time of each current is expressed in percentage, and the display value of example t is 100%, indicating tripping; TIf the displayed value is less than 100%, it indicates that it is started.
(3) Start, trip, LED alarm lamp fault reset
When the yellow start lamp, red trip lamp and red LED alarm lamp are on due to fault, the lamp will remain after the fault disappears, but the contact of its fault output cannot be maintained. When the fault disappears, click “Picture” and all fault lights will go out.
(4) Steps of modifying fixed value
For example, to change the protection setting of overcurrent protection (I>) from 1.46In to 1.88In, the steps are as follows:
① . In the main menu ABB status, press the “Picture” key 4 times, and “SETTING” appears;
② Press the “Picture” key to enter the “PROTECT. STAGES” submenu under “SETTING”;
③ Press the “Picture” key, and the submenu “I>In: 1.46” will appear on the screen;
④ Press the “Picture” key, and the “* GROUP 1 I>: 1.46” submenu will appear on the screen;
⑤ Press the “Picture” key, “PASSWORD: 000” will be displayed on the screen, and the operation password is required. You can use the “Picture, Picture, Picture, Picture” key to change “000” and enter the correct password;
⑥ Press the “Picture” key, then the screen returns to “* GROUP 1 I>: 1.46” and flashes. You can use the “Picture, Picture, Picture, Picture” key to change 1.46 to 1.88, and then press the “Picture” key.
Note: If the microcomputer device is set as the default password “999”, step ⑤ can be omitted. You can press the “Picture” left key to return to the main menu level by level, or directly press the “Picture” key to return to the main menu ABB status. For other settings such as “I>>” for quick break protection, the steps are the same as above. The difference is that after step 3, press the “Picture” key until the corresponding “I>>” submenu appears, and then press step 4 for operation.
(5) . Modify time steps
In the main menu ABB status, press the “Picture” key five times to display “CONFIGURATION”, press the “Picture” key to display the “CONFIGURATION” configuration submenu, press the “Picture” key six times to display “TIME”, press the “Picture” key to enter, and you can modify the date and time respectively.
