Abstract

The present disclosure relates to a measurement method of the insulation resistance to ground of a conductor, a controller and a control system. The method includes the following steps that: first current flowing through a test resistor when a first output terminal is connected with the conductor and the second end of the test resistor is grounded is obtained; the secondary side output open-circuit voltage of a transformer, second current flowing through the test resistor when the first output terminal is in butt joint with the second end of the test resistor, and a first voltage between the first output terminal and the second end of the test resistor when the first output terminal is in butt joint with the second end of the test resistor are obtained; and the insulation resistance to ground of the conductor is determined according to the secondary side output open-circuit voltage, the first current, the first voltage and the second current. Therefore, the insulation resistance to ground of the conductor can be quickly and accurately obtained. The measurement circuit of the insulation resistance to ground of the conductor is simple, the components of the measurement circuit are low in cost, and the measurement accuracy of the measurement circuit is high. With the measurement method adopted, the defect rate of a glass substrate manufacturing process can be effectively reduced, and the yield and quality of products can be improved.

Description

technical field [0001] The present disclosure relates to the field of electronic technology, in particular, to a method for measuring insulation resistance of a conductor to ground, a controller and a control system. Background technique [0002] In the manufacturing process of the glass substrate, when the insulation effect of the platinum channel to the ground is not good, the ion state of the molten glass liquid in the platinum channel will change, so that the glass substrate is prone to defects. Therefore, quickly and accurately detecting the insulation resistance of the platinum body to ground has an important impact on the defect rate control in the glass substrate manufacturing process. Contents of the invention [0003] The purpose of this disclosure is to provide a measurement of conductor-to-ground insulation resistance in order to solve the problem that the defect rate in the glass substrate manufacturing process cannot be effectively controlled due to the inabi...
