Precautions For Using Gpo3 Laminate in High Voltage Cabinet

As for the insulation condition of domestic gpo3 laminated high-voltage switchgear, it is necessary to cut off the power of the equipment, and then conduct the test with preventive partial discharge However, because this experiment has a long preventive test cycle, it is difficult to find the insulation defects of high-voltage switch between oneortwo experiments This article will introduce and analyze the new insulation performance detection and fault diagnosis technology of high gpo3 laminated switchgear There are two main methods for on-line detection of insulation gpo3 performance, which are based on the principle of ultrasonic and TEV. These two methods have a rich data base. They can not only check the status of power equipment, but also provide safety guarantee for the operation of high-voltage switchgear
