| A, explosion-proof electrical control box overview: DKXB series explosion-proof electric control box (hereinafter referred to as the control box), in accordance with the GB3836-2000 "regulations of explosion-proof electrical equipments used in explosive gas environment, design and manufacturing. Explosion-proof marks: Exd IIBT4. Can be applied to a combustible gas mixture with air to form explosive mixture (which belongs to Ⅱ class-level T4 group) and the following places, but does not contain metal and insulation damage in the surrounding medium of the active chemicals, for ac 50 hz / 60 hz, 660 v / 460 v / 380 v / 220 v / 110 v circuit, as a branch of power, lighting switch. The application of the second distribution box, explosion-proof electrical environment 1, either altitude does not exceed 2000 m 2, working temperature is 20 ℃ - - + 40 ℃ Around 3, belonging to the class IIB T4 group explosive mixture of dangerous sites 4, the relative humidity is not more than 90% (+ 25 ℃) 5, indoor outside, all can use The structure of the three, explosion-proof electrical control box overview: Distribution box shell is made of high strength aluminum alloy casting or of high qualified steel plate welding, inner chamber air switch, through the lever operation switch on the cover, cover and shell with screw fastening, "it is strictly prohibited to charged open cover" shown on the cover of warning card in order to protect security, terminal box with terminal blocks, lead available G3/4 - G2 steel or rubber cable into line with different diameter, internal with made of H62 copper platoon terminals, has the ideal conductivity, shell protection IP54. Fourth, explosion-proof control box use and maintenance 1, check whether meet the requirements before install and use explosion-proof marks and warning marks After installation of 2, check the fasteners should be complete without defect 3, inspection or maintenance should be power off before you open the lid 4, non-professional personnel can|t operate 5, shall regularly check, if find abnormal phenomenon should immediately repair, protect flame-proof surface during installation. After the repair should be on the flame-proof tu rust-proof oil 204-1, in case of rust. 6, should be periodically repair, cleaning, wipe with a clean cloth when cleaning, cannot use chemical cleaner, so as not to damage the paint layer. Five, the transportation, storage of explosion-proof electrical control box 1, distribution box, avoid severe shock and vibration during transit 2, power distribution box should be stored in ventilated and dry warehouse |
