Purpose and scope
This device used in coal mine underground (methane and coal dust gas danger) 127 v, 1.2 KW, 1.5 KW hand electric drill in remote control, this device is in accordance with the domestic coal mine underground use of comprehensive protection of the coal electric drill in the actual operation of the existing problems, and developed a new type of non-contact coal drill comprehensive protection are unprecedented in the country. It can eliminate the coal electric drill of ac
contactor contact rebound produced by the mechanical vibration, edm, electromagnetic interference and reverse instant overvoltage, have leakage, short circuit, network insulation monitoring and so on many kinds of protection function, and light color display device fault and running state.
Coal drill dont work, cable not charged. The device adopts the type pilot control circuit, the use of the main transformer in the controlled device does not work not charged not only save electric energy, and safe and reliable. The main circuit of on-off use advanced solid state relay, realize the coal drill open
contactless control, secondary controller circuit relay contact voltage of dc 10 v, current 5-10 ma, improve the small relay work stability, so the service life
up to ten million times maintenance free.
Technical parameters
The device adopts the type pilot control circuit, the use of the main transformer in the controlled device does not work not charged not only save electric energy, and safe and reliable.
ZBZ coal drill protection function: short-circuit, overload, leakage blocking and leakage protection. System is equipped with a dry type transformer "triad"
type integrated device.
