Shandong golden age Plastic Engineering Co., Ltd.
1. current transformer fault
1.1 poor manufacturing processes
Capacitive current transformer insulation wrap does not have occurred outside Pine, paper fold tight, capacitive touch screen offset or "leg" injury occurred when defects such as insulation, can cause insulation breakdown accident occurred in the run.
1.2 seal is bad, the water damp
Transformer oil in the water, or end-cap within the rust, can make insulation from moisture. Some sealed transformer cannot ensure the sealed, resulting in stagnant water. Leaking into the wave of mainly on the top screw hole and diaphragm to aging and cracking of the place.
1.3 installation and maintenance and operator error
Common installation and maintenance personnel install or repair the wire connector loose, bad oil injection, secondary winding circuit, capacitor end shield of grounding and poor, leading to overheating and discharge so that chromatographic analysis of abnormal results.
