On-line insulating monitoring device for TFT-LCD glass kiln and channel construction

The utility model discloses an on-line insulating monitoring device for TFT-LCD glass kiln and channel construction, and the device comprises an insulation value detection electronic circuit which is connected with different glass machined segments of a steel structure. A detection signal collected by the insulation value detection electronic circuit is inputted into the controller, and the controller is externally connected with a monitoring display and parameter setting module which can achieve bidirectional data transmission with the controller. The monitoring display and parameter setting module achieves the value display of the detection signal inputted by the controller, and outputs a comparison parameter of the detection signal to the controller. The controller is also externally connected with an alarm which is used for the prompting of the comparison results of the detection signal. The device tests the voltage of the steel structure at a constant current state, and then inputs the voltage into the controller, thereby calculating the resistance value of the steel structure. Through the comparison of the detection signal with a set value of the monitoring display and parameter setting module, the device judges whether the insulation value of the steel structure is qualified or not, sends out an alarm signal through the alarm for an unqualified steel structure, and generating a corresponding fault report.
