應(yīng)用電流差動(dòng)保護(hù)比較進(jìn)入和離開受保護(hù)的架空線路或電纜的電流。需要一個(gè)可靠的通信設(shè)施，以便在線路末端的終端之間進(jìn)行信息交換。該差動(dòng)功能為輸電、輸電和配電網(wǎng)絡(luò)提供分相真電流差動(dòng)保護(hù)。它在所有方面都是一個(gè)數(shù)字系統(tǒng)，用于現(xiàn)代數(shù)字通信系統(tǒng)，包括多路復(fù)用和路由交換系統(tǒng)。電流在每相的基礎(chǔ)上進(jìn)行比較，避免了電流求和方法的問(wèn)題，并為單極跳閘提供了相位選擇信息。
ApplicationCurrent differential protection compares thecurrents entering and leaving a protectedoverhead line or cable. A dependable communication facility is needed to allow information exchange between the terminals at theline ends.This differential function offers phase-segregated true current differential protection fortransmission, sub-transmission and distribution networks. It is in all a numerical systemfor use with modern digital communicationsystems including multiplexed and routeswitched systems. Currents are compared ona per phase basis, obviating the problem ofthe current summation approach and providing phase selection information for singlepole tripping.
