Research On Condition-based Maintenance And Test System Of Distribution Network Switch Cabinet Of Baotou Power Supply Bureau

At present,most of the distribution network around the switchgear maintenance or system follows the periodic maintenance,periodic maintenance can be found defective equipment in time,help reduce accidents,to ensure safe operation of equipment has played an important role.But only use periodic overhaul maintenance mode,single management mode,and failed to run the actual situation of the equipment in maintenance mode,can't adjust according to the condition maintenance model,the periodic maintenance will cause not timely troubleshooting and cause the operation of the system is not safe,but some equipment maintenance overdo,waste of money and manpower.As today's society in the power system to large capacity and large system,automated direction,periodic switchgear maintenance system is no longer adapt to the needs of the development of power system.Distribution switchgear state overhaul implementation will become the important measure of distribution network equipment management,distribution network switchgear state overhaul not only reduce the maintenance cost,reduce the manpower cost,reduce the excessive maintenance equipment,improve the efficiency of power supply,to increase the security of the distribution network operation with important significance.In this paper,the basic concept of distribution network switchgear,structure,composition,classification and operation characteristics are summarized and introduced.Of Baotou Power Supply Bureau under the jurisdiction of the summary and analysis on the common faults of distribution switchgear,and gives the corresponding switchgear equipment test items and overhaul the method of the test.Introduces the basic theory of the state overhaul,and switchgear for Baotou region distribution network in recent years,the law of the running condition and fault are summarized and analyzed,according to the theory of state overhaul design distribution switchgear state evaluation method and the state overhaul of strategy,and complete the design of distribution network switchgear state overhaul and test system.In actual operation of the Baotou Power Supply Bureau using the designed switchgear state overhaul and test system,and according to the state overhaul scheme and the implementation of the pilot project for field operation.According to the distribution network in Baotou Power Supply Bureau switchgear state overhaul project summary and analysis on the actual operation data,the distribution network switchgear state overhaul and the conclusion of experiment system run effectively.
