BZC53 proof operation column BZC53 supply prices direct proof operation column I. Purpose and Scope BZC51 / BZC53 explosion-proof operation column (hereinafter referred to as the operation column), is based on national standards GB3836.1-2000 "Electrical apparatus for explosive gas atmospheres - Part 1: General requirements "and GB3836.2-2000" Electrical apparatus for explosive gas atmospheres - Part 2: flameproof "d" ", GB3836.2-2000" Electrical apparatus for explosive gas atmospheres - Part 1: increased safety "e" "The design and manufacture for explosive gas atmospheres (Zone 1 and Zone 2), IIB \ IIC T6 class group and the following explosion hazard, in AC 50Hz, rated voltage of 380V or DC rated voltage up to 220V, rated current of 10A circuit in electrical solenoid for remote control purposes. Button with ammeter can also monitor the operation of the circuit. Second, the product model BZC51 / 53 - □□□□□□ fifth unit: G: Hanging L: The fourth unit vertical: Switch Specification Code III: second unit indicator Specification Code: ammeter specification code first Unit: Button specification code total unit explosion-proof operation column 51: IIB level 53: IIC Class Code Code button buttons contact form Ⅰ Ⅲ Ⅱ a normally open a normally closed 1NO + 1NC two normally open two normally closed 2NO 2NC three basic parameters of a) AC Frequency: 50HZ; b) rated working voltage: DC220V, AC220V, AC380V; c) Rated working current: 10A; d) proof mark: EXdeIIBT6 ExedⅡCT6; e) Protection class:. IP54 IP65; f) Corrosion grade: WF1 3 altitudes column can operate reliably under the following conditions a) the installation site does not exceed 2000m; b) an ambient temperature of -20 ℃ ~ + 40 ℃, and 24h average does not exceed 35 ℃; c) the installation site The air relative humidity at the highest temperature of + 40 ℃ when not more than 50%; at a lower temperature allows a higher relative humidity, the wettest month average minimum temperature does not exceed + 25 ℃, the monthly average maximum relative humidity not more than 90%; d) in the absence of severe vibration, shock and shake the place; e) containing explosive gas atmospheres place; f) to prevent rain and dripping in place invasion; g) Pollution levels for three. h) Installation category: Ⅱ class four, the main structure of the operation column shell casing made of aluminum alloy casting, surface electrostatic spray, interior lights, buttons, universal switch and ammeter, according to user requirements equipped with other instruments, Explosion-proof button ultrasonic packaging process, to ensure a reliable bond strength, buttons can be freely combined two units, proof indicator by special design, AC 220V ~ 380V universal. Exposed fasteners are made of stainless steel, the use of anti-out design, user-friendly installation, maintenance; according to user requirements, equipped with rain cover, using the pipe or cable wiring. Five, explosion-proof operation column Products BZC51-D2K1 (II type) two light switches hanging a BZC51-B1K1 G (III type) a table a switch hanging BZC51-K2 G (III type) two switches hanging BZC51-B1D2K1 G (IV type) a table two light switches hanging a BZC51-A2D2k1 G (IV type) two buttons two light switches hanging a BZC51-A2K1 G (II type) two buttons one switch, pendant BZC51-A2D2 G (II type) two button two lamps hanging BZC51-A2B1 G (III type) two buttons a table hanging BZC51-A2 G (I type) two buttons hanging BZC51-A2B1D2 G (IV type) two buttons a table lamp hanging two six, Installation and maintenance of an operation column before installation, you should check whether the nameplate says technology listed according to the instructions for use and basic parameters consistent with the actual usage and check component damage, all parts are intact, normal. Installation is first introduced into the device via cable connected to the terminals increased safety chamber and compression seals, sealed the cable, connect the ground wire, tighten the screws, check the above is correct, namely can be powered using; 2 column may not disassemble operation, maintenance, after-shave off the power supply before opening the lid front stage repair or replace the lamp; 3 Operation column should be regularly checked and found damaged parts should be replaced. .
