When this system uses, at monitoring terminal leakage current sensor, microprocessor, power supply and radio communication unit are set, monitoring system is provided with monitor server and wireless telecommunications gateway on the backstage simultaneously; Like this, the leakage current sensor of monitoring terminal can be in real time be sent to the wireless telecommunications gateway with supplemental characteristics such as the leakage current of the insulator surface of gathering and the pulse frequency and temperature, humidity through radio communication unit.The monitoring system on the backstage, wireless telecommunications gateway are accepted the data that transmit from the monitoring terminal radio communication unit and are sent to monitor server to carry out data processing.The insulator data that monitor server is returned to transmission are analyzed, thereby can in time grasp the long-pending dirty state and the development trend thereof of insulator surface, and cross in filth and to send alerting signal in limited time so that in time handle.
The beneficial effect of the utility model is: intelligent electric transmission line isolator leakage current monitor system that the utility model provided can in time grasp the long-pending dirty state and the development trend thereof of insulator surface, crosses in limited time in filth, sends alerting signal.Simultaneously, this system also can effectively prevent and reduce circuit pollution flashover and ice sudden strain of a muscle accident, improves line security operation and information system management level.
Description of drawings
Fig. 1 is the structured flowchart of intelligent electric transmission line isolator leakage current monitor system.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is done further explanation.
As shown in Figure 1, this novel backstage monitoring system that comprises, the backstage monitoring system mainly is made up of interconnected monitor server and wireless telecommunications gateway; Also have the monitoring terminal that is installed on the transmission line of electricity, this monitoring terminal mainly is made up of leakage current sensor, microprocessor, power supply and radio communication unit; Above-mentioned leakage current sensor one end is connected with transmission line of electricity, and the other end is connected with microprocessor with data bus through address bus; Above-mentioned radio communication unit is connected with data bus through address bus with microprocessor, radio communication unit and the wireless connections of wireless telecommunications gateway; Above-mentioned power supply is electrically connected with microprocessor, radio communication unit and leakage current sensor respectively.
The intelligent electric transmission line isolator leakage current monitor system that this is novel to provide can in time grasp the long-pending dirty state and the development trend thereof of insulator surface, crosses in limited time in filth, sends alerting signal.Simultaneously, this system also can effectively prevent and reduce circuit pollution flashover and ice sudden strain of a muscle accident, improves line security operation and information system management level.
Though be described in conjunction with the embodiment of accompanying drawing the utility model, in the claim institute restricted portion of this patent, the protection that those skilled in the art do not need various modifications that creative work can make or distortion still to receive this patent.
