Description
Product Overview:
The coal mine charger transformer, for underground, powers chargers, ensuring safe charging and smooth mining ops.
Specific Introduction:
1.Protection: With winding embrace for vib-res, flame-retardant (std), Class F insul. It resists harsh mine env, averts failures, extends life.
2.Efficiency: 98%+ conversion. Cuts energy use, suits mine's large power need, gives stable output, hikes benefits.
3.Safety: PT100 monitors temp, warns. Wide-freq volt output, copes with grid, stops damage, cuts risks.
Operation Environment
A) Altitude: Not exceeding 1000m, shall be derating used if above 1000m;
B) Ambient Temperature: -25℃~55℃.
C) Relative Humidity: ≤95%;
D) As to the installation site, to make sure no bad effect on transformer insulation, chemical deposition, dust, and other explosive or erosive medium.
E) The supply voltage approximates sinusoidal wave, and the three-phase voltage is relatively balanced.
