LXDC Current Transformer Amsa da kawo gaba na LXDC

Ukura na Mbuga

Zero-Sequence Current transformer na signal equipment da kuma protective relaying equipment idan power system ya gina zero sequence earthing current, yana amfani da component na equipment don in samu protective ko monitoring function. Yana amfani da stainless steel metal shell da kuma installation mai ban sha'awa, yana haifar da kyau, high accuracy zero sequence CT suka fi shirya a cikin power system (kamar neutral earthing, big current earthing, small current earthing ko arc suppression coil earthing) etc.

Muhimman Fasahar

• High-Precision Current Measurement: Yana amfani da high-permeability silicon steel core, tana samun accuracy class 0.2S tare da error ≤0.2% a nan 1%~120% of rated current, tana tabbatar da high-precision requirements for energy metering devices. Secondary rated current tana ba da zaɓi 5A/1A options don in iya haɗa da measuring equipment interfaces daban-daban.

• Wide-Range Adaptive Design: Current ratio tana haɗa da 50/5 zuwa 2000/5A, tana ba da flexible range switching via multi-tap design (misali, dual ranges of 200/5A and 400/5A). Tana da dynamic response range of 1:100, tana biyan da normal load monitoring da kuma large-current measurement during short-circuit faults.

• Fully Enclosed Insulation Structure: Ana faɗinsa ta hanyar vacuum-cast epoxy resin tare da IP65 protection rating, tana taimaka wajen kawo shekaru, salt fog, da dust. Insulation materials tana da shiga UL94 V-0 flame retardant grade, tana da shiga -40℃~+85℃ temperature range, tana da shiga harsh environments kamar outdoor substations da humid basements.

• Anti-Saturation & Transient Response Characteristics: Core tana amfani da special magnetic circuit design don in bazu saturation under short-circuit current (20 times rated current), tana tabbatar da transient current waveform fidelity. 5P20-class protection windings tana da shiga rapid action requirements of relay protection devices, tare da action time ≤10ms.
