Product Description

KBSG series mining dry type transformer is a kind of electricity supplying and distribution equipment in the coal mine, it is equipped with explosion-proof enclosure, independent high and low voltage connecting cable cavity, device of inputloutput cables and movable supporting bracket and wheels.
KBSG series mining explosion-proof dry type transformer is used as power supply device for comprehensive coal machine, transportation machine, pump station, fan and so on, in the three phase neutral point ground disconnected power supply system of AC50Hz, first side rated voltage is 10KV or 6KV, second side rated voltage is 3450V/1200V/693V/400V in the places of coal mine, colored metal mine and tunnel project where are filled with methane mixture, coal dust and powder dust.

Model Description

Technical parameters and structure dimensions

Product structure features

1. Multiple protective functions of overload, short circuit, leakage, leakage lockout, over-voltage, under-voltage and over-temperature.
With RS485 interface for computer communication.
Excellent explosion-proof performance and sufficient mechanical strength.
2. The Main insulating material is C-class and Nomex paper is adopted, plus the oxygen-free copper winding, which ensures the small partial discharge, small no-load and load loss, and low-temperature rise. 250kva Explosion proof dry type transformers for Underground coal mines
3. Special anti-loose structure with vertical lifting ability, no internal looseness during transportation, easy to use and maintain.
250kva Explosion proof dry type transformers for Underground coal mines
4. Superior silicon lamination for steel core, the lamination joint is processed by oblique cut angle and the latest new technology “seven-step”, which ensures small no-load loss and current.
5. Equipped with rail wheels, strong impact resistance ability, detachable and adjustable rail gauge.
