Product DescriptionKBSG 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 DescriptionTechnical parameters and
structure dimensionsProduct structure features1. 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 mines3. 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 mines4. 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.Environment condition1. The altitude does not exceed 2000
meters, and the ambient atmospheric pressure is 80-110KPa2. The
ambient temperature is -5ºC~+40ºC3. The relative temperature of the
surrounding air is not more than 95% (+25°C)4. In the environment
with the danger of methane explosive mixture and coal dust
explosion5. In an environment without gas or steam that destroys
insulation6. In a place without significant shaking and shock
vibration7. The installation slope with the horizontal plane should
not exceed 15°8. Places that can prevent dripping9. Installation
