Background technology
Distribution line is conveying, the main thoroughfare of distribution electric energy and instrument, connects electric substations at different levels and user, is power train The important component part of system, includes internal factor and external factor, distribution network failure master the reason the fault of power distribution circuit Singlephase earth fault to be had and phase-to phase fault, analyze the reason cause distribution line failure and the form of fault can be for processing event The counter-measure of barrier offer science.
The fault of distribution line is mainly as follows:
1st, distribution line self reason:During erecting power transmission lines, circuit is long, the branch of circuit is more, makes Wire connects confusion, may cause the short circuit of circuit.It is also to cause circuit that the equipment of connection line joint easily occurs aging Short-circuit the reason, in addition, the big wire of excessive low resistance insulator, part span makes sag larger etc., and defect may be to distribution wire Fault is brought on road, and circuit overload also can cause fault;When power consumption is big, distribution line electric current increases above safe electricity , there is breaking accident in the possible fused wire of flow valuve;Circuit design is unreasonable to also result in circuit overload;Distribution transformer occurs Fault or arc short-circuit is likely to result in controller switching equipment misoperation.
2nd, external factor causes line fault:Because distribution line is distributed in outdoor, line operation environment is not only in Plain Environment is preferably local, also the place of the bad environments such as mountains and rivers, waste Australia, and distribution line can more be subject to the shadow of natural environment Ring.In addition, human factor is also the reason causes distribution line failure, circuit may suffer artificial intentional destruction, stolen etc. Cause line fault.
According to the Fire-Fighting Bureau under the Ministry of Public Security 2005 to 2010 statistics, China's electrical fire incidence all near or above 30%, Occupy first of all kinds of cause of fire, and according to 2003 to 2007 domestic particularly serious electrical fire fire origin statistics, " electric wiring Causing fire " ratio reaches 58.44%, ranks first, and the fault electric arc in distribution line is the main cause that electrical fire occurs.
Electric arc in low-voltage distributing line by its property have " good ", " bad " point, so-called " bad arc ", refer in particular to " fault electricity Arc ", the time that it occurs in electrical system is unpredictable with place, and generation scale and duration are difficult to control to, and easily hold Continue, develop, spread, the equipment that ultimately causes is damaged with circuit, until leading to electrical fire, by there is position, fault electric arc may be used again It is divided three classes:A. the electric arc between energized conductor (phase line and phase line, phase line and the neutral conductor), also referred to as " arc resistance short circuit ", because Electric arc is in parallel relationship with the normal load on circuit, is also called " parallel connection type electric arc ";B. powered electric conductor and earth conductor (such as:PE line, equipment external conductive casing etc. of ground connection) between electric arc, also referred to as " arc resistance earth fault " or " arc resistance leakage Electricity ';C. energized conductor itself fracture or the electric arc producing because of loose contact, because electric arc and load are in series relationship, also referred to as " string Connection type electric arc.
It is impossible to report to the police to the place of breaking down in time when distribution line breaks down at present, and because staff exists During inspection, workload, therefore needs to design a kind of numeric type electric power it is impossible to keep in repair to faulty line in time than larger Distribution line failure arc detection analysing terminal.
