Research On Integration And Application Of Pilot Distribution Network Emergency Equipment

The current distribution network in shenzhen and defects of the traditional operation method is most commonly.Homework after needs to find fault or defective equipment,first to isolation of equipment failure or defects,not failure or defects to turn power supply operation,restore its power supply.And then apply for spare parts supplies,wait for after the goods arrived at the scene for fault(defects)equipment replacement,after the test qualified,complex operation,all customers thus restore power.Distribution network,therefore,ring network cabinet,transformer and other main equipment failure or emergency,major defects,material distribution and site equipment installation time is long,seriously affect the fast reply message time.Draw lessons from international and domestic advanced,with bypass power in power distribution network,standby power supply,load transfer of power or not less outage operation method,can effectively solve the above problems,greatly improve the power supply reliability.According to the operation of power equipment is charged don't blackout practices can be divided into two kinds: one kind is can be directly in the electric circuit and equipment maintenance,namely charged homework;Another kind is not directly to live working of power distribution equipment,need to use mobile power supply(mobile power car,load transfer,etc.),the bypass cable will need to repair,repair equipment is separated from the grid,power cuts after processing,back to repair before.Bypass between the repair technique as a new type of distribution network,has been applied in several domestic power companies.But because of the limitations on equipment electrical properties,the technology on overhead lines to carry out the more,and can only meet in the part of the branch users apply on line.In shenzhen,distribution network cabling in power distribution lines and the proportion of more and more big,because the cable is changed distribution network the restriction of the ring network cabinet five prevention system,bypass charged if not breakthrough work,the application can't meet the needs of the development of distribution network in shenzhen.Characteristics of distribution network,therefore,it is necessary to combine shenzhen for cable bypass operation of key equipment and technology for tackling key problems,make the safe and practical technology can apply to most of the distribution network line,make its application range is more widely used.
