The system provided by the invention can be used for mastering the condition and development trend of dirt retention on the surface of the insulator in time and giving out an alarm when dirt exceeds the limit; and simultaneously, the system provided by the invention also can be used for effectively preventing and reducing the pollution flashover and icing flashover accidents of the line and improving the safe operation and informatization management level of the line.
Description
Technical field
The present invention relates to transmission line of electricity on-line monitoring technique field, be specifically related to a kind of long-pending dirty state and the development trend thereof that can in time grasp insulator surface, cross in limited time, send alerting signal in filth.Simultaneously, also can effectively prevent and reduce circuit pollution flashover and ice sudden strain of a muscle accident, improve the intelligent electric transmission line isolator leakage current monitor system of line security operation and information system management level.
Background technology
Because transmission line of electricity is dispersed on the wide region and open-air weather conditions are abominable, be suspended on outdoor insulator surface for a long time and form filth easily, under the bigger weather of humidity, be easy to take place pollution flashover, have a strong impact on the reliability of supply line.The main manual patrol that relies on of traditional power transmission line route insulator contamination inspection lacks monitoring means effectively, can't in time grasp the long-pending dirty state and the development trend thereof of insulator surface.
Summary of the invention
The purpose of this invention is to provide a kind of intelligent electric transmission line isolator leakage current monitor system, be intended in time to grasp the long-pending dirty state and the development trend thereof of insulator surface, cross in limited time in filth, monitoring system is sent alerting signal to the backstage.
The objective of the invention is to realize like this: a kind of intelligent electric transmission line isolator leakage current monitor system, comprise the backstage monitoring system, said 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.
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 invention has the beneficial effects as follows: intelligent electric transmission line isolator leakage current monitor provided by the present invention system 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 present invention is done further explanation.
As shown in Figure 1, the present invention includes the backstage monitoring system, 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.
Intelligent electric transmission line isolator leakage current monitor provided by the present invention system 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.
