Ki jan transfòmatè aktyèl sekans zewo yo itilize an konbinezon

Zewo Sekans aktyèl transfòmatè a sanble de bwat fè sikilè nan aparans, men li se tou yon eleman nan dèlko dyezèl la. Estrikti li yo sanble ak sa yo ki nan yon transfòmatè aktyèl òdinè atravè nwayo, eksepte ke likidasyon prensipal li se twazyèm pati nan sistèm nan pwoteje. Kondiktè a nan chak faz, likidasyon segondè a reflete aktyèl la zewo-sekans nan sistèm prensipal la.

The Zero Sequence Current Transformer should be installed on the bottom plate of the switchgear and should be fixed by a reliable bracket. However, some manufacturers or construction units install the Zero Sequence Current Transformer> current transformer on the bracket under the switchgear bottom plate, and some even bundle the Zero Sequence Current Transformer>transfòmatè aktyèl sou kab la, ki vyole sele total la nan kabinè a switch. Nan prensip, li pa ni an sekirite, ni pousyè-prèv, ni ti bèt, kite anpil danje kache.

After the cable terminal head passes through the external Zero Sequence Current Transformer> current transformer, the relative position of the metal shielded ground wire of the cable and the external Zero Sequence Current Transformer>transfòmatè aktyèl la pa kòrèk.

Zero Sequence Current Transformer>current transformer secondary connection piece was opened during cable construction, and was not restored in time after the work was completed, resulting in open circuit of current transformer>bobin segondè transfòmatè aktyèl la.

Fen a tè nan fil tè a nan djenn metal la nan kab la pa soude ak tèminal, ni li pa konekte ak ba an kwiv mete nan kabinè a switch, men se dekontrakte lapped sou boulon yo nan kabinè a switch.
