(A)BGP_1—6型矿用隔爆高压配电装置我国煤矿井下一直使用 PB_2—6及 PB_3—6型高压隔爆配电装置。该产品采用多油断路器。我国现行的标准《爆炸性环境用防爆电气设备》GB3836规定高压隔爆配电装置不准采用多油断路器。我国煤矿井下千伏级供电,需要高压6kV 电缆直接送到采区配电点,要求对高压电缆必须有漏电及监视保护。近几年来,研制成功的国产BGP_1—6型、BPG_2—6型、BGP_3—6型高压隔爆配电装置和过去老产品相比,有很明显的优点:开断容量大,经过试验达到
(A) BGP_1-6 mine flameproof high voltage power distribution device China’s coal mine has been using PB_2-6 and PB_3-6 high voltage explosion-proof power distribution device. The product uses multi-oil circuit breakers. China’s current standard “explosion-proof electrical equipment for explosive atmospheres” GB3836 provides high-voltage explosion-proof power distribution unit is not allowed to use multi-oil circuit breakers. China’s coal mine kilovolt-level power supply, the need for high voltage 6kV cable directly to the mining area distribution points, requiring high-voltage cables must have leakage and monitoring protection. In recent years, the successful developed BGP_1-6 type, BPG_2-6 type, BGP_3-6 high-voltage explosion-proof power distribution devices and the old products in the past compared to the obvious advantages: breaking capacity, after the test reached
