1.產(chǎn)      品      詳      情      資      料：   

ABB RDNA-01是一款數(shù)字式直流電流差動(dòng)保護(hù)裝置，主要用于高壓直流輸電系統(tǒng)中的電流保護(hù)和故障檢測(cè)。它可以測(cè)量電流信號(hào)，將其與設(shè)定值進(jìn)行比較，并在出現(xiàn)故障時(shí)通過(guò)切斷故障部分的電路來(lái)保護(hù)設(shè)備和系統(tǒng)。

配置方面，RDNA-01包括數(shù)字信號(hào)處理器、輸入電路、輸出電路、通訊接口等部分，具有高精度、高可靠性、快速響應(yīng)等特點(diǎn)。

在應(yīng)用方面，RDNA-01主要應(yīng)用于直流輸電系統(tǒng)中的保護(hù)和控制，包括電纜保護(hù)、母線保護(hù)、斷路器保護(hù)、換流站保護(hù)等。它可以保護(hù)直流輸電系統(tǒng)的各個(gè)部分，防止電流過(guò)載、短路等故障，提高電力系統(tǒng)的穩(wěn)定性和可靠性。

ABB RDNA-01 is a digital DC current differential protection device mainly used for current protection and fault detection in high-voltage DC transmission systems. It can measure the current signal, compare it with the set value, and protect the equipment and system by cutting off the circuit of the faulty part in the event of a fault.

In terms of configuration, RDNA-01 includes a digital signal processor, input circuit, output circuit, communication interface, and other parts, featuring high accuracy, high reliability, and fast response.

In terms of application, RDNA-01 is mainly used for protection and control in DC transmission systems, including cable protection, bus protection, circuit breaker protection, converter station protection, etc. It can protect various parts of the DC transmission system, prevent current overload, short circuit, and other faults, and improve the stability and reliability of the power system.
