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.
Application: KL6LM(B) Intrinsically Safe Type Miner's Lamp, this product is a portable lighting tool, mainly suitable for underground lighting, but also for tunnels, high-altitude and field operations.
It is used in coalminesin three-phase neutral ungrounded transmission lines with voltage AC 3300V,50Hz. It canmake local and remote control of three-phase asynchronous motor and concentrated control of coal cutter,scraper conveyor, crusher,reversed loader, pump station and other equipments of comprehensive mechanized coalfaces.
It is suitable for the mine with explosive dangerous gas and coal dust. It can control and protect the start and stop of less than 4 three-phase squirrel cage asynchronous motors in the AC 50 Hz and rated voltage ac1140v (660V), and the phase sequence can be changed when stopping. It is especially suitable for the centralized monitoring of mining, transportation, coal mining and other dynamic loads.
