Description
Technical field
The utility model relates to cable maintenance field, particularly a kind of cable degree of aging evaluating system based on dielectric response.
Background technology
Along with a large amount of uses of cable, the cable of small number did not accumulate operation more than 10 years, and the fault of mesolow cable also comes out gradually.Nowadays cable plays more and more heavier role in city powers, and it is also proposed requirements at the higher level to the overhaul efficiency of cable.Except improving the technological means of site examining and repairing, we think and are more necessary that the state to cable is estimated, the cable higher to some accident probabilities carries out early stage preventive maintenance, can not only maintenance workload be alleviated like this when arriving in maintenance peak period, the social performance that stable city powers can also be played.And the aging feature being cable and stepping into excessive risk accident, we go to supply a gap by various technological means as far as possible in investment allowed band, to play the aging effect of cable that delays, thus avoid the aging various burst accidents brought of cable to a certain extent.
Therefore, be necessary to work out a kind of cable degree of aging evaluating system based on dielectric response, to make preventative maintenance task in advance, avoid the generation of various burst accident.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of cable degree of aging evaluating system based on dielectric response, to make preventative maintenance task in advance, avoids the generation of various burst accident.
The purpose of this utility model is achieved through the following technical solutions:
Should based on the cable degree of aging evaluating system of dielectric response, comprise frequency conversion time histories sample signal generator, high-speed data acquisition card, A/D converter, central processing element, display and host computer, described frequency conversion time histories sample signal generator is connected with cable insulation, described high-speed data acquisition card input end is connected with cable conductor, described high-speed data acquisition card by the analog signal transmission that collects to A/D converter, simulating signal is converted to digital signal by described A/D converter, and be transferred to central processing element, described central processing element is connected with a storer, cable data is stored in described storer, the output terminal of described display and host computer and central processing element electrically connects, central authorities' display chip recalls cable data corresponding in storer according to the digital signal received, and generate cable Ageing Model by after the digital signal received and cable data process, this model is transferred to display and host computer by described central processing element.
Further, described central processing element is connected with host computer by USB or RS232;
