The disadvantages of gpo3 insulation materials can be divided into two categories.
Category 1: combined with the disadvantage of neutralization. If the porcelain of suspension insulator is cracked; The insulation part of the generator set is damaged, crushed and broken; Cable wires are provided by.
When the gpo3 laminate is charged and discharged after the magnetic density is generated, the working standard voltage will destroy it, and other gpo3 mechanical equipment will be damaged and damp.
The second is the widespread defect, which refers to the reduction of the overall insulation characteristics of electrical equipment, such as motor, transformer, waterproof sleeve and other insulation defects. Moisture regain and embrittlement of equipment raw materials.
When the above two defects occur in gpo3 insulation, its characteristics will usually change. Then we can test the hidden defects according to some tests.
