Two,Application and scope
           The device is used in underground coal mine (methane and coal dust gas hazard)127V1.2KW-1.5KWThe remote control of hand held coal electric drill is the existing problem in the actual operation of the comprehensive protection of coal electric drill used in coal mine underground in China, and a new type of contactless comprehensive protection device for coal electric drill is developed at home. It can eliminate the mechanical vibration, electric coal drill work of AC contactor bounce spark, electromagnetic interference and reverse transient overvoltage, has the protection function of leakage, short circuit, network insulation monitoring, and color display and operation state of device fault. When the coal electric drill does not work, the cable is not charged.
  The device adopts the skip type pilot control loop, the main transformer is not charged when the controlled equipment does not work, not only saves the electric energy, but also is safe and reliable. The on-off of the main circuit adopts the advanced solid state relay, which realizes the contactless control of the coal electric drill. The voltage of the circuit relay contact voltage of the two controller is DC10VCurrent5-10mA,The working stability of the small relay is improved, and the service life of the whole machine is up to ten million times.
