Packaging, storage and acceptance
The packaging, storage and transportation
1, ring network cabinet in the factory for a single wooden box packaging. Tipping, inversion and violent vibration is not allowed during storage and transportation.When handling does not allow on the ground directly push and pull: in no lifting device, in the packaging box sleeper pad cylinder. the slide into installation position.
2, to prevent rain, damp cabinet.
3, ring network cabinet should be placed in good ventilation, and can prevent the intrusion of various harmful gases. Strictly forbidden to store in the same warehouse with chemical drugs, acid and alkali. etc..
The acceptance
1 before unpacking, check the packaging is damaged, when unpacking to protect product.
2 of the cabinet appearance: at the same time to check whether the cabinet components are damaged, parts comply with the packing list3 check the random file is complete.
A, product use instructions and components in the cabinet:
B, factory test report:
C, product certification;
D, packing list;
E, two wiring diagram.
Installation and commissioning
1. installed first ring network cabinet placed in the installed base, and neat, debugging, and then use fasteners good
2. The installation of main bus bar installation, open bus room, bus connection contact surface should be smooth, no dirt.
3. A ring network cabinet grounding should be grounded, and the ground loop check
4. Delta debugging according to ring network cabinet use components manual and cabinet manual debugging.
5. Installation and commissioning of, each switch element and the anti misoperation mechanism 5 operations, and no abnormal phenomenon, that switch machine normal operation.
Use and troubleshooting
The electricity before check
The electric performance, insulation level and wiring correctness of all components in the cabinet should be checked before the power supply is sentCheck all normal to be put into operation.
Delta normal operation state.ln normal operation, whether entering line cabinet or outgoing cabinet, load switch should be in the closing position, grounding knife in the closing position, the cabinet in the locked state.
A fault handling
1.In the cabinet into line fault maintenance, should first cut off the power line, the load switch tripping, charged display cabinet check, confirm that there is no voltage. grounding knife, opened the door for maintenance.
2.In the outgoing cabinet troubleshooting, should first breaking load switch cabinet and closing earthing knife, opened the front door for maintenance, the mistress line at this point in the charged state.
Maintenance and repair
A ring network cabinet in the following circumstances the need for maintenance and repair:
1.check the insulation level of the product after 5 years of operation;
2.after the load switch is broken for 100 times, the main back is arranged in neat, good debugging, and then fasten with the fastening piece.
