KBSGZY Mining Explosion Proof Movable Transformer Substation

Use
KBSGZY mining explosion proof movable transformer substation consists of dry type transformer, cable connector for mining explosion proof movable transformer substation, low voltage feeding switch(or low voltage protection box) for mining explosion proof movable transformer substation. The substation has protection performance such as electric leakage, leakage latch, overload, short circuit, over-voltage, under-voltage, etc.
KBSG mining explosion proof movable transformer substation is a kind of movable whole set supplying and transforming power equipment in coal mine. It is used in the coal mine where is filled with methane mixture gas and dust , it also can be used in the environment where is filled with gas and vapor which do not corrode metal and damage insulation property.

Meaning of type
KBSGZY-Mining explosion

Technical descriptions
1.Transformer’s iron core is made of high quality cold rolling Grain-Oriented thin silicon steel plate which adopt no punching hole colligation processing craft to decrease empty load loss of iron core and current of empty load. The transformer has the features of low loss and low noise. The enclosure is designed with no hang core structure to avoid inside looseness during transportation. The enclosure adopts grade H or C insulation material which has characteristics of fire-proof, no harmful gas and pollution.
2.Adopts Dupont Nomex-T410 insulation paper between winding teams and layers to ensure winding teams electric performance efficiently. So the transformer has strong heat impact resistance, high overload capability, excellent short-circuit resistance, good insulation performance to ensure transformer overload capability in a short time.
3.Adopts international advanced VPI vacuum pressure dipping lacquer equipment and craft to dip it in H grade no solvent insulation lacquer to avoid the aging breakdown caused by long-playing discharge. Winding teams will improve its mechanical strength and damp-proof performance after dipping, drying and solidifying.
4.High and low voltage switches use reliable and stable LCD intelligent protector to realize simple operation, wide setting range, short step size, high control precision.
5.High voltage switch has complete protection functions of overload, short circuit, under voltage, over-voltage, over-temperature; It also has the functions of remote monitor , remote surveillance and fault checking.
6.Low voltage switch has complete protection functions of overload, short-circuit, electric leakage ,leakage latch ,phase imbalance protection, wind and electricity gas latch, etc.; it also has the indication functions of system real-time voltage and current parameters.
7.The malfunctions on low voltage side drive high voltage side breaker to break through signal cable, decreases break-down current, overcomes breaking malfunctions due to big current of switch on the low voltage side of substation, also overcomes dead zone problem that is electric leakage in circuit can’t break malfunction point from transformer low voltage winding group to low voltage feeding switch.
8.High and low voltage switches have memory function of permanently stores various data and transmits recorded data.
9.Standard RS-485 communication interface is available for data transmission.
