The high-vol煤矿防爆车sxqianglitage flameproof switc您看矿井hgear is a key apparatus for6kV-power S煤矿井下6upply system 井下防爆开闭in underground mines. The switchgear isused for supplying Power energy to HV working machinery or next IVdistribution station in coalface. However , there have been manydisadvantages with the HV flameproof switchgear widely used inunderground for long time , such as smaller breaking capacity,***r protection system and higher fault probability , whichimpairs the reliability , safety and continuity of undergroundpower distribution system.It is hence important to develop a kindof new intelligent protection system with wonderful performancesused in flameproof switchgear which can not only improve the supplyquality of underground HV distribution system but also perfect itsprotective properties.Especially can prevent the underground fromgas explosion and guarantee the operating safety for undergroundworker.
