Analyze And Research The System Of Online Detection Shear Wire Fault

When analyzes the online electric wire(cable) characteristic we discovered that many characteristics will changes along with the online electric wire(cable) in factor under human and so on environment influences. For example electric wire resistance, electric wire reactance, online electric wire temperature and so on. Analytical study online electric wire's some characteristics, have the inspiration significance and the use value to electric power department's some breakdowns. The article analysis online electric wire characteristic will obtain the electric wire impedance to obvious change when factor and so on human or environment influences. Using this characteristic and unifies a peripheral unit, the article studies a set to be possible to use for to examine the ordinary shear the electric wire and the new shears the electric wire breakdown plan. This article take the online electric wire characteristic analysis as a premise, unifies the Microcontrollers, DSP and GSM, studies a set of electric wire examination supervisory system plan. This plan can discover rapidly shears the electric wire breakdown, and send the warning to the manager. The research content mainly includes:First, through to the online electric wire characteristic analysis, obtain the impedance change relations with different material electric wire before the breakdown and after. Using this change relations, analyzes and the construction model. Analysis examination voltage value's ordinary examination method and from the definition examination voltage value electric circuit and the error analysis,and carries on the analysis comparison to both situation. Conducts the simulation research to the model, to proved that the model to the breakdown is effective.Second, through to online electric wire characteristic analysis, unifies the Microcontrollers, DSP and GSM, studies a set of electric wire examination supervisory system plan. This system has the dual measuring abilities: The first is examination monitoring in online situation direct shear electric wire method; The second is examination monitoring time being near early morning, in electric wire load very low situation, The thief use the lateral section thin electric wire or price small advantage electric connection in some electric wire both sides.This method maintains the first electric power is unimpeded, then shear middle electric wire.
