KBSG2-T mine flameproof dry type transformer

Introduce:

KBSG2-T mine flameproof dry type transformer(mobile substation) is suitable for methane mixed gas and coal dust, and there is adanger ofexplosionin the mine environment. but also suitable for metal corrosion and destroy theinsulation ofgas and steam environment. the transformer has high strength. low temperature rise.heatdissipation and moisture resistance. easy maintenance and so on.

mine flameproof dry type transformer fault analysis and troubleshooting

Fault phenomenon Cause analysis Elimination method
The temperature is too high or local overheating 1. Overload operation
2. Coil insulation damage causes local leakage
3. Core loss increases.
1. Check the usage load and adjust it
2. Repair the damaged parts
3. Repair the core
Abnormal or excessive noise 1. The iron core is loose
2. The coil pressure is loose
1. Tighten the bolts
2. Tighten the screws and tighten the coil
Low insulation resistance Damp insulation Bake or no load gradual transmission
Casing live 1. Casing is stained or damaged
2. The insulation of the lead cable is damaged or the bare cable is in contact with the cover
3. Low voltage coil leakage to the core
1. Decontamination or replacement
2. Identify the cause and eliminate it
3. Find out the part of leakage and eliminate it
