ABB 3BHE024577R0101 PPC907BE drive controller control system intelligence

Description

▲ When the handcart in the main switch room of the high-voltage cabinet is in the test position, PPC907BE must close the secondary aviation plug of the handcart before swinging the handcart to the working position; Before the handcart is pulled out to the service trolley, the secondary aviation plug of the handcart must be pulled out first, otherwise the secondary aviation plug will be damaged.
▲ Under normal conditions, PPC907BE should close the door of the main switch room of the high-voltage cabinet tightly before shaking the handcart; In special cases, if you want to open the door and shake the handcart, you must first insert the black interlocking block in the middle of the handcart beam into the gap between them with a slotted screwdriver to unlock.
▲ The handlebars on the left and right sides of the handcart crossbeam must be manually pulled to their places on both sides before the handcart can be shaken.
▲ The circuit breaker must be opened before the handcart can be shaken; When the circuit breaker is closed, the handcart can only stop by shaking for half a circle.
▲ When the circuit breaker handcart is being moved from the test position of the high voltage cabinet to the working position, it should be slowly moved clockwise. If it is blocked, do not force it to operate, but exit in time for relevant inspection.

▲ If the handcart is equipped with handcart locking electromagnet RL2 (generally, the handcart with circuit breaker can not be equipped with handcart locking electromagnet RL2, while the isolation vehicle must be equipped with handcart locking electromagnet RL2, whose resistance value is about 2K Ω for DC110V and about 8K Ω for DC220V), the electromagnet must be powered on before the handcart can be shaken. If the power is lost, PPC907BE should first remove the panel of the isolation vehicle, and then use pointed nose pliers to manually pull the iron core of the handcart locking electromagnet to the left. After unlocking, To shake the handcart.
4.2.1 Move the circuit breaker handcart from the service trolley to the high-voltage cabinet test position
(1) Check: the main switch room of the high-voltage cabinet is clean and free of sundries. Check that the circuit breaker number corresponds to the cabinet number of the high-voltage cabinet, and confirm that the secondary aviation plug of the circuit breaker has fastened the positioning screw of the partition on the circuit breaker.
(2) Push the service trolley to the front of the high-voltage cabinet, adjust the height of the trolley workbench, make the positioning pin smoothly insert into the positioning hole, and lock it with the high-voltage cabinet through the lock key.
(3) Slide the handles on the left and right sides of the circuit breaker handcart beam, and at the same time retract them to release the interlock between the handcart and the service trolley workbench, and at the same time, push the circuit breaker handcart to the high-voltage cabinet test position.
(4) Pull the black ball handle of the positioning pin of the service trolley to the left to release the interlock between the service trolley and the high-voltage cabinet, and pull out at the same time.
(5) Check whether the handles on the left and right sides of the handcart beam of the circuit breaker are flexible, pull them manually to both sides, and fasten the high-voltage cabinet.
(6) Pull out the secondary aviation plug that is fastened to the diaphragm set screw on the circuit breaker, insert it into the high-voltage cabinet socket, and close it. Note: do not touch the secondary aviation plug locking rod on the main switch room of the high-voltage cabinet.
4.2.2 Remove the circuit breaker handcart at the test position of high-voltage cabinet to the service trolley
Operate in reverse order according to 4.2.1. Note: The secondary aviation plug of the handcart must be pulled off first, and then fastened on the positioning screw of the upper partition of the circuit breaker before other operations are carried out, otherwise the secondary aviation plug will be damaged.
4.2.3 Shake the circuit breaker handcart from the test position of the high-voltage cabinet to the working position
(1) Check: the secondary aviation plug on the circuit breaker truck shall be closed. Otherwise, shaking the handcart will damage the aviation plug.
(2) Confirm that the circuit breaker is in the opening position, the handcart is in the correct test position, the handles on the left and right sides of the handcart are in place correctly, and the corner angle of the square operating rod of the screw mechanism in the middle of the handcart beam is upward. After confirmation, close the main switch room door of the high-voltage cabinet.
(3) Turn the slide in the middle of the main switch room door with the door key, open the operation hole, insert the trolley crank vertically, and cover the square operating rod of the trolley beam middle screw mechanism.
(4) Turn the crank of the handcart clockwise, slowly shake it for 20 circles to stop (stroke: 20cm), and it cannot be shaken again. At this time, the crank of the handcart is still in the original vertical direction, and the red indicator light of the handcart working position is on, indicating that the handcart has been working.
(5) Pull out the crank of the handcart.
4.2.4 Shake the circuit breaker handcart out of the working position of the high-voltage cabinet to the test position
Operate in reverse order according to 4.2.3.
4.3 Local and remote closing/opening operation
This operation refers to the electrical operation with DC power supply for the secondary of the high-voltage cabinet. The circuit breaker handcart must be in the test/working position.
4.3.1 Local operation of high-voltage cabinet and low-voltage chamber panel
(1) . Local closing/opening button operation of low-voltage room panel: turn the handle of local/remote transfer switch to the “local” position, press the closing green button once, and the high-voltage cabinet is closed; Press the red opening button again to open the high-voltage cabinet.
(2) Local closing/opening operation of the REX521 panel of the motor cabinet microcomputer: turn the local/remote transfer switch handle to the “remote” position, select “control” from the main menu of the microcomputer, → right-click “manual control”, → right-click “local and remote=local”, “↓” press “control CB=breaker opening”, press “E” twice, the high-voltage cabinet is closed, and press “E” twice again, the high-voltage cabinet is opened.
4.3.2 Backstage PLC remote operation
Turn the handle of the local/remote change-over switch on the low-voltage chamber surface to the “remote” position, and the background PLC can be switched on/off.
Note: This project cancels the background remote PLC closing/opening operation, but maintains the background remote emergency trip function.
