摘要
井下高压防爆配电装置对于煤矿电路的安全稳定有着重要意义。介绍配电装置的主要结构,提出当前配电装置的脱扣器存在的问题,利用机械阻尼延长跳闸时间,降低失压对电路产生的影响,该装置实用效果良好,值得推广使用。
The explosion-proof power distribution equipment is important for the security and stability of the coal. This article describes the main structure of the power distribution unit and rases the prob lems of the current release. We use mechanical damping to extend trip time, reducing influence from the loss of pressure generated by the circuit. This design has practical effect and should be introduced.
