ZJZ2-10/1140(660)SM This device is suitable for underground coal mine containing coal dust and explosive gas (methane). It can control the power supply of 127V grade lighting signal equipment, and the power supply is introduced as 50 Hz 1140V or 660V. The device has the functions of microcomputer monitoring and intelligent protection. The intelligent integrated protector takes high-performance single chip microcomputer as the core, adopts military grade peripheral chips and high-performance precision converter. Through modular hardware design and unique software algorithm, it has strong anti-interference ability, reliable action and high sensitivity of protection. It has good man-machine interaction interface, Chinese LCD display, menu operation, password authorization, anti misoperation, query and modification, fault memory and other functions. It has standard Modbus communication protocol, which is convenient for docking and monitoring with other automation equipment.

The permanent magnet synchronous motor adopts centralized winding, optimal pole slot coordination, and rotor structure integrating isolation, stress, positioning and lightweight, with small rotational inertia, small leakage flux, large main flux, higher power factor and higher efficiency. 

KBA176 mine explosion-proof optical fiber camera (hereinafter referred to as camera) is used for image capture and transmission in important places in underground mines. It is suitable for underground coal mines that contain explosive gas mixtures such as methane and explosion hazards.

This product uses computer chips, with software modulation and programming functions, adding 15 adjustable channels. Working in 144MHz ~ 166MHz frequency band, the transmitting power can be adjusted from 0.3W to 1.2W. The sensitivity of receiving is higher. It has the function of anti-interference of mute audio, which makes the communication effect clearer and the working performance more stable, safe and reliable. Handheld station is an extension of mine leakage communication system, which is used by underground mobile personnel.
