Embodiment Construction
[0071] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0072] figure 1 Among them, the power cable sheath grounding current state monitoring and analysis system includes an application server 1, which communicates with a resource manager 2, a front-end control machine 3, a monitoring management station 4, a voice manager 5, a short message manager 6 and a data browser respectively. 7 connections; the front-end controller 3 is connected with at least one monitoring host 8, and the monitoring host 8 is connected with at least one data acquisition device 9; wherein,
[0073] The data collection device 9 collects the grounding current data of the sheath and the temperature of the cable joint;
[0074] The monitoring host 8 receives the data collected by each data acquisition device 9, and uploads the data to the front-end controller 3 for monitoring and analysis;
[0075] The front-end control machine 3 trans...

The invention relates to a state monitoring and analysis system of power cable sheath grounding current and a method thereof. The state monitoring and analysis system has the advantages of automatically detecting the operation state of a power cable so as to provide strong guarantee for evaluating whether the operation state of the power cable is good or not, capability of notifying maintenance personnel of fault information in various alarming forms in time so as to provide guarantee for timely maintenance of the cable and the like. The state monitoring and analysis system comprises an application server which is respectively connected with a resource manager, a front-end controller, a monitoring management station, a voice manager, a short message manager and a data browser, wherein thefront-end controller is connected with at least one monitoring host computer, and the maximum connection quantity reaches 255; and the monitoring host computer is connected with at least one data acquisition equipment, and the maximum limit is related to actual laid lines. The application server is a core software module, other software modules can correctly work only when the application server is operated normally, other modules can not directly communicate with each other, and connections among the modules are all transferred by the application server.
Description
technical field [0001] The invention relates to a system for monitoring and analyzing the grounding current state of a power cable sheath and a method thereof. Background technique [0002] At present, most power companies in the country are still in the planned maintenance stage for the management of the main cables in the power tunnels and tube wells, and generally use the method of regular inspections to check the operation status of the cables. From an economic point of view and a technical point of view, planned maintenance has great limitations: for example, regular testing and maintenance have caused a lot of direct and indirect economic waste, and many insulation defects and potential failures cannot be found in time. At the same time, with the accelerated development of cities, the rapid growth of power tunnels, and the sharp increase in power loads, the operation and maintenance of power grid power tunnels and working wells are facing tremendous pressure: how to en...
