Check and maintain ring network cabinet

Check:

1. Check whether the grounding of the ring network cabinet is loose. If it is found, it should be tightened in time to prevent the over-current damage of the ring network cabinet.

2. Check whether there is dust or other foreign matter on the surface of the ring cabinet. If found, should be cleaned in time, to avoid a large amount of dust accumulation, affecting the performance of the ring network cabinet.

3. Check whether the insulation part of the ring network cabinet fails, check whether the pressure of the insulating gas is normal, and prevent the normal use of the ring network cabinet. 4. Pay attention to the contact reliability of the circuit. Therefore, it is necessary to check the ring network cabinet high voltage cable, check whether the cable damage, aging or discharge. If the above abnormal phenomenon occurs, relevant measures should be taken to deal with it effectively. It can be replaced to ensure the normal operation of the ring network cabinet. 5. Check whether the operating mechanism of the ring network cabinet is flexible, whether there is damage or rust, etc. If any damage occurs during maintenance, take measures.

6. Check the real-time display of the ring network cabinet and whether the instrument is normal. For example, voltmeter, ammeter, etc. indicate the same value as the actual situation.

7. Check whether the outer cabinet of the ring network cabinet is cracked, deformed or worn. If any of the preceding symptoms is found, take proper measures to rectify the fault. If any problems are found during the process, please contact the manufacturer for technical support.

Maintenance:

1. Routine maintenance and repair with each quarter for routine maintenance cycle maintenance repair work target, its concrete content is mainly to the operation state of adjustment and waste removal work target, which belongs to the normalized inspection maintenance work target, is an indispensable part in it.

2. Improve the condition maintenance of ring grid cabinets. It is based on the extensive synchronous control and inspection of the operation status of 10kV ring grid cabinets. It is an important link, it can ensure the safety factor of all high voltage switchgear and the operation of colleges and universities, in terms of the whole power supply network, it improves the overall reliability and safety factor.

3. Targeted maintenance and maintenance This type of ring network cabinet has a long maintenance cycle with many specific contents, usually 1 to 2 years. The specific contents are to extensively dissolve ring network cabinet and do well large-scale maintenance, especially the maintenance and maintenance of the knife switch in the cabinet. In addition, according to the characteristics of industrial equipment is not the same as far as possible to carry out different levels of maintenance solutions, generally speaking, the primary equipment of the ring network cabinet is as widely as possible to carry out safeguard measures test, and as far as possible to carry out maintenance and disassembly is generally secondary industrial equipment.
