DBQX型斷相保護器由斷相鑒別電路、時間產生控制電路、安全動態(tài)輸出驅動電路等組成,它和保護繼電器JWXC-1700配合,用于保護三相電動轉轍機正常工作。產品穩(wěn)定性好,故障率低;控制時間由單片機電路構成,準確性高,響應時間短;產品采用了標準的安全型繼電器結構,便于安裝使用。
DBQX type limited-time phase-failure protector consists of phase-failure discriminating circuit, time generation control circuit, safe dynamic output drive circuit, etc. It cooperates with JWXC-1700 protection relay to protect the normal operation of three-phase electric switch machine. The product features good stability and low failure rate. As the control time is composed by the microcontroller circuit, it has high accuracy and short response time. The product uses a standard safety relay structure, which is easy to install and use.
