LXK110 Current Transformer

Product Overview

Ang zero-sequence current transformer nagpadayon sa pag-ugmad sa signal equipment ug protective relaying equipment kung ang power system mogenerate og zero sequence earthing current, giaktibar nito ang mga komponente sa equipment aron makamit ang function sa proteksyon o monitoring. Gigamit niini ang stainless steel metal shell ug madaling i-install na nakapahimulos sa dako, daghang mga specs sa high accuracy zero sequence CT gikinahanglan sa power system ( sama sa neutral earthing, big current earthing, small current earthing o arc suppression coil earthing) etc.

Key Features

• High-Sensitivity Zero-Sequence Current Detection: Gidisenyo para sa ground fault monitoring sa power systems, mahimong mohatag og accurate detection sa zero-sequence components nga giproduce sa vector sum sa three-phase currents (kasagaran as low as several milliamps). Ang paggamit sa high-permeability cores ( sama sa nanocrystalline/permalloy) ug special winding designs, gituyo nito ang linear response sa 0.1A~100A zero-sequence current range, suporta sa reliable early warning sa ground faults.

• Anti-EMI Structural Design: Ang core nagpadayon sa magnetic shielding technology, ug ang mga windings gibulag sa double-layer shielding aron maputli ang power grid harmonics (3rd, 5th harmonics) ug external electromagnetic interference ( sama sa lightning, switching operation pulses). Naka-pass sa IEC 61000-4 EMC tests, it maintains measurement accuracy ≤1% sa complex electromagnetic environments.

• Wide Frequency Response Characteristics: May frequency response range gikan sa 10Hz~100kHz, accurately detects 50/60Hz power-frequency zero-sequence currents ug captures high-frequency ground transient signals ( sama sa arc grounding overvoltage harmonics). Suitable for various system grounding modes, including ungrounded neutral and arc suppression coil grounding.

• Fully Enclosed Insulation and Protection Design: Nagpadayon sa epoxy resin vacuum casting fully sealed structure nga may IP65 protection rating, resist moisture, salt fog, ug dust. Suitable for harsh environments sama sa outdoor cable trenches ug humid basements, ang maintenance-free design reduces O&M costs.
