Embodiment
[0057] Such as Figure 6 The automatic online test of the withstand voltage performance of the copper clad laminate includes the following steps:
[0058] Step 1: Stack the copper clad laminates to be tested neatly on the hydraulic lifting platform, set the voltage value on the touch screen 7 of the control cabinet 14 to 3500V, the boost rate to 20V / s, the withstand voltage time to 60s, the discharge voltage to 60V, and the discharge time 100s;
[0059] Step 2: The feeding suction hoist 23 picks up a piece of copper clad laminate and puts it into the feeding platform 24, the feeding platform 24 rotates, and sends the copper clad laminate to the liftable transmission mechanism of the high voltage test platform 15, and the transmission mechanism Fall, put the copper-clad laminate on the high-voltage test platform 15, start the test device, and enter the test state;
[0060] Step 3: Under the control of the digital controller 1, the test device first closes a pair of pressurize...

The invention discloses an automated online testing method for voltage resistance of a flaky material. The automated online testing method includes that testing parameters are set, a testing device is started, and voltage is increased to a set value for a voltage increasing test; if the material is not punctured at the set voltage value and within voltage-resistant time, voltage resistance of the material is qualified, if not, voltage resistance of the material is not qualified; the voltage value is lowered to zero, the testing device is stopped after the inside of the testing device discharges to set discharging voltage, an external discharging device is connected for further discharging, and the test is finished after discharging is completed. By the automated online testing method, the problem that an existing mode of manual sampling inspection can cause material waste, is prone to causing damage to the surface of the material during discharging and cannot realize online comprehensive testing of the whole material is solved, and artificial intervention is not needed in the process of testing, so that danger of people hurting caused by discharging is reduced, and testing efficiency is improved greatly. The automated online testing method is suitable for large-scale online testing of voltage resistance of the flaky material.
Description
technical field [0001] The invention belongs to the technical field of electric insulation test methods for sheet materials, and in particular relates to an automatic online test method for voltage resistance performance of sheet materials. Background technique [0002] In online production, it is necessary to test the withstand voltage performance of the sheet material. The existing detection method usually adopts the method of manual sampling inspection. After the withstand voltage test is completed, the insulating material needs to be discharged. Since the high-voltage tester cannot completely discharge the residual voltage inside the material, it is necessary to manually discharge the insulating material. It is impossible to accurately know the residual voltage of the material. How high it is, arcs are generated during the discharge process, which is easy to cause damage to the surface of the material. In this way, the integrity of the sampled materials is destroyed due...
