High voltage cable boxes BHG1-315 / 10

BHG1 series flameproof high voltage cable boxes 1 Scope This standard specifies the requirements for the user to understand the products, proper handling, installation, use and maintenance and content. 2, the implementation of standard junction box to perform GB3836.1 ~ 3-2000 and MT / T946-2005 "coal with increased safety high voltage cable boxes" and Q / GD001-2008 "flameproof high voltage cable junction box" standard. 3. Overview 3.1 junction boxes for explosive gas (methane) and coal dust mixture of coal mine coal mining Tunnelling connecting the power cable circuit wiring purposes. It can be used for rubber and armored cable. Model meaning 3.4 3.2 Ex-mark: "ExdI" 3.5 Explosion-proof type: Flameproof 4, junction boxes suitable for the working conditions following the working environment: altitude less than 1000m; ambient pressure (86 ~ 110) kpa; ambient temperature ( -20 ~ + 40) ℃; air relative humidity less than 98% (+ 25 ℃ when); with coal mine methane and coal dust explosive mixture; no significant shake and severe shock and vibration environments; in no damage to the metal and insulation of gas and vapor environment; Pollution degree: 3; Installation category: Class Ⅲ A purpose: BHG1-315 / 10-2G flameproof high voltage cable boxes (hereinafter referred to as junction boxes), applicable to explosive gas (methane) mines and coal dust mixture, the coal mine for voltage to 10 kV, current up to 400,315 amperes system rated current up to 12.5KA disconnect the power supply system, connecting two mining rubber-sheathed cables purposes. II. Technical Data: Model Rated voltage Rated current into the cable type concentric ring groove diameter (mm) Dimensions BHG1-315 / 10-2G 10KV 400 315 200 armored cable 88 970 × 385 × 220 three structural profile junction box. flameproof enclosure for the steel structure and cover bolts crimp form, on both sides of the power supply pins, and a control line into devices. Housing equipped with three main terminals, the terminals platen crimp the cable head. Base of high-voltage porcelain, and has an auxiliary terminals. IV. Use 1, after unpacking the junction box should be checked for damage phenomenon, whether the missing parts. 2, the junction box non-powered operation, you must press the "Coal Mine Safety Regulations" operation, the installation of the cable installation process must be strictly enforced, can be carried out in the underground, the specific installation process, refer to "BHG1-400 / 10-2G mine explosion high-voltage cable junction box "instructions. 3, to remind that the outlet section should fill the epoxy resin at the time of installation. Check with the cable junction box at the same time, such as the temperature exceeds 80 ℃, should immediately identify the reasons for timely resolution of checking To check the fasteners, warning signs are complete.
