BXD52防爆检修动力配电箱|防爆电源开关配电箱作用和适用范围
1 the role and scope of application
BXD52系列防爆检修动力配电箱（以下简称检修箱）是按GB3836.1-83《爆炸性环境用防爆电气设备 通用要求》，GB3836.2-83《爆炸性环境用防爆电气设备 隔爆型电气设备“d”》设计和制造。检修箱主要用于1区和2区中含有爆炸性混合物为Ⅱ类B级T4组及以下爆炸危险场所，作为交流50Hz，额定电压至380V，分支回路额定电流至100A的电路中作不频繁接通与分断之用，且具有过载和短路保护。
BXD52 series explosion-proof overhaul power distribution box （hereinafter referred to as the overhaul box） is based on GB3836.1-83 "explosive environment with universal explosion-proof electrical equipment requirements", GB3836.2-83 "electrical apparatus for explosive gas atmospheres flameproof electrical apparatus" "d" design and manufacturing. Overhaul box is mainly used for the 1 and 2 areas containing explosive mixtures for class II B and below T4 group explosive dangerous location, as the exchange of 50Hz, rated voltage up to 380V, the circuit branch circuit of rated current to 100A in not frequently switching on and off with, with overload and short circuit protection.
