Detailed Description

Lighting Signal Integrated Protection Device Lighting Signal Integrated Protection Device Product Application Lighting Signal Integrated Protection Device is used in the coal mine 127 v lighting and signal power control of the load, and with short circuit protection, leakage atresia, leakage action and cable insulation dangerous indication etc. Comprehensive flameproof electrical apparatus. Triad structure form, can replace the existing 2.5 and 4 kva dry type transformer and manual flame-proof switch multibody control mode. Lighting Signal Integrated Protection Device Working Condition （1）not more than 2000 meters above sea level; （2）The ambient temperature is not higher than +40 ℃, not lower than -20 ℃; （3）ambient air relative humidity less than 95% (+25 ℃); （4）In the absence of a strong jolt wave vibration and vertical gradient of not more than 15 degrees above; （5）In the absence of enough to corrode metal and damage the insulation of gas and steam environment; （6）can be used in a dangerous gas methane and coal dust in mines; （7） to prevent water and liquid immersion area. Lighting Signal Integrated Protection Device Technical Feature 1、lighting circuit protection time: less than 0.15 seconds, the signal short circuit protection time: less than 0.4 seconds. 2、the leakage resistance to ground movement setpoint 1.5KΩ (1.5K ~ 3KΩ adjustable). 3、the leakage resistance to blocking the action value 3KΩ ± 1KΩ 4、 cable insulation dangerous indicated value 11KΩ ± 2KΩ. 5、leakage protection operation time is less than 0.25 seconds. 6、the working voltage fluctuation allowed: Ue ± 10%. 7、Dimension: ZBM (BZX)-4C 605 × 480 × 605 8、Weight: 95kg (128kg) Lighting Signal Integrated Protection Device Structure Summarize Synthesizing means flameproof enclosure is cylindrical, having a convex bottom and the lid. Shell cover and turn the cover shell body using only the mouth structure. Housing upper part of a cable junction box as leads. Shell operated isolating switch fitted with the right handle, start and stop buttons and then test short circuit, leakage protection system is an effective test button. And a reliable mechanical interlock devices to ensure that when the isolating switch is closed, the shell lid open; 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. Main transformer and chassis connected by slide structure, easy maintenance.
