The Survey Systematic Researcher And Application’s Anlysis In The Intellectual Cable Route

In recent years, with the fast development of the urban construction. The Electriccable received extensively application, and the work of maintain has increased atdouble. Because the database hasn’t been set up, the survey and differentiation ofcable route become very important to cable maintain work. If the cable route unable tobe defined, it will increase the damage rate of cable during the construction. It isunable to find the trouble point of the cable if the cable route is unknown, and it willinfluence the efficiency of power recovery. So the researcher of the intellectual cableroute survey system has very important social and economical benefits.Nowadays, the cable Detector mainly used in china is the imported Pipelineinstrument. Whose function is single, and need artificial differentiation, as well asexperience. Pipeline instrument is very expensive and it takes a long time to finish atext. the intellectual cable route survey system was invented by our bureau with thecooperation of Co., Ltd. of letter of Zibo in2008. by tested, the system can meetrequirement of the Distribution network in FuZhou, solve the problems of cablemaintain. Improve the cable Management level.First of all, This text analyzed the traditional cable survey principle, improvedthe performance of detecting devices, developed the intelligence system which cansurvey the cable route under the operation state. Secondly, the system use doublefrequency technology and digital signal treatment technology, which can inhibithigher harmonic wave, improve the anti-interference ability surveyed in cable route,solve the interfere’s problem of the line of neighbor. With the phase place parameterand arrow point function, it realized the intellectuality of the cable route survey; and itOffered accurate method and80%measure method..it solved the problem of thecable route accurate survey,offers the technical support for mixing the distributionnetwork This system uses the low frequency, large power input signal, which makesthe surveying cable can reach two kilometers, basically meets the real work demand.The invention of this system, will change hazard current situation. it is simple tohandle, but effectively. It can accurately distinguish the cables, reduce unnecessarypower cut, improve the distrubition nework management level.
