Comprehensive security lighting comprehensive security lighting, lighting comprehensive security prices, comprehensive security lighting lighting manufacturers comprehensive security product uses comprehensive security lighting for power control coal mine 127V lighting and signals the load and short circuit protection, leakage lockout, leakage action and cable insulation Indication of danger, such as integrated flameproof electrical equipment. Triple formal structure, multi-body control can replace the existing 2.5 and 4KVA dry-type transformers and switch manually explosion. Zmjt11 comprehensive security lighting conditions (1) no more than 2000 meters above sea level; (2) the ambient temperature is not higher than + 40 ℃, not lower than -20 ℃; (3) the relative humidity of the surrounding air is not greater than 95% (+ at 25 ℃); (4) in the absence of a strong top-wave vibration and local vertical gradient of not more than 15 degrees; (5) in the absence of enough to corrode metal and damage the insulation of gas and vapor environment; (6) can be used to have methane gas and coal dust in the mine danger; (7) to prevent water and liquid immersion places. Lighting features a comprehensive security technology, lighting circuit protection time: less than 0.15 seconds, the signal circuit protection time: less than 0.4 seconds. 2, leak resistance movement to the setting value 1.5KΩ (1.5K ~ 3KΩ adjustable). 3, leak resistance to blocking the action value 3KΩ ± 1KΩ 4, indicating the risk of cable insulation value 11KΩ ± 2KΩ. 5, leakage protection operating time of less than 0.25 seconds. 6, the working voltage allows the fluctuation range: Ue ± 10%. 7, Dimension: ZBM (BZX) -4C 605 × 480 × 605 8, machine weight: 95kg (128kg) lighting comprehensive security architecture overview flameproof enclosure integrated device is cylindrical, with a convex bottom and lid. Cover and shell body shell structure using port forwarding cover only. Upper shell has a cable junction boxes as leads. Right side of the shell with an operating isolation switch handle, start and stop button and pick test short circuit, leakage protection system is an effective test button. And a reliable mechanical interlock device to ensure that when the isolating switch is closed, not open the case cover; when the housing cover is open, isolating switch can not be closed. Shell cover side has a perspective mirror, one can observe the status indicator from the outside. Connecting the main transformer and chassis using the slide structure, easy maintenance. The product has been exported to many countries, the United States, France, Canada, Indonesia, Russia, Vietnam, Australia, South Korea, Iran, was unanimously praised by customers.
