This type equipment apply to excavating work in the mine. When the gas explosion, the coal dust explosion, fire and so on make the air short oxygen or take poison air to menace the safety of workers life in the mine, the mining workers can take this equipment to flee for their lives. The range of application: This type equipment generally use in the middle, small mine and big mine matched with pressed wind self rescuer or refuge cave. The equipment also can use in other under earth engine, chemical engine and the possible take place the poison air or short oxygen to menace the life of workers.

After AC current goes through rectifying transformer to change voltage, putting into the single-phase full-wave rectifying circuitry which made up of silicon rectifying components to be DC. Output voltage regulates the once voltage of transformer by booster. Electronics & Electrical >> Others | |
