摘　　要：移频自动闭塞以移频轨道电路为基础,以钢轨作为传输通道传递信息。移频自动闭塞抗干扰性能强,适用于电气化和非电气化区段。ZPW-2000A型无绝缘移频自动闭塞具有轨道电路传输安全性、传输长度、系统可靠性、可维修性等特点。ZPW-2000A型无绝缘移频自动闭塞轨道电路系统主要是由室外部分、室内部分和系统防雷三部分组成。Frequency shift automatic block to shift the frequency track circuits based on the information passed to the rail as a transport channel. Frequency shift automatic blocking anti-jamming performance for electrified and non-electrified section. ZPW-2000A Non-Insulated frequency shift track circuits with automatic blocking transport security, transport length, system reliability, maintainability characteristics. ZPW-2000A uninsulated frequency shift automatic blocking system is dominated by the outdoor part of the interior components and systems lightning three parts.
