零相変流器は一般的に貫通型が採用されており、鉄心内に三相導体を一括で通し、二次巻線をその上に巻いて磁気的な平衡を保っている。一般的な変流器と違い、零相変流器は三相導体を一括で通している。
The ZCT is addressed like some other CT: ratio, polarity, precision course (saturation). The one consideration that is usually diverse is definitely the Bodily dimensions on the window considering the fact that you are going to run all three phase cables by way of that window.
"Security" CT's are produced so as to sustain precision at recent ranges considerably in extra in their nominal values, generally 20 periods nominal, as a way to insure right representation of currents beneath fault circumstances.
This ring style latest transformer will be able to harmony the zero sequence existing while in the a few section technique. This is where it received its name as being a Zero Sequence Present-day Transformer (ZCT).
新エネルギー発電の知識 新エネルギーとして代表的な太陽光発電、風力発電、燃料電池や、排熱再利用など。
Subsequently, the CBCT’s secondary-related earth fault relay will become activated, isolating the wellness procedure which has a circuit breaker.
Second, Examine if capacitive present-day of cable is below your location. 2A looks is small setting, for cable dimension, from 120mm^2 is fewer than 1km lenght.
そのためあらかじめ漏電遮断器に内蔵され、絶えず事故検知の役割を担っています。 零相変流器の使用用途
地絡時には零相変流器が作動することにより、故障個所を周囲の電気回路からただちに切り離されます。
高圧ケーブルには「遮蔽層」と呼ばれるものがあります。これを「シールド」とも呼びます。この記事では一般的なシールドで統一します。シールドの役割や目的は次の事が挙げられます。
The core balance present transformer (CBCT) is mainly useful for earth fault security of electrical equipment. Among its crucial applications is earth fault protection of induction motors, that is mentioned underneath in detail.
The principal part of ZSCTs is to boost system security by detecting faults, specially ground faults and leakage currents. When this kind of faults come about, the ZSCT activates, cutting off the facility supply here to avoid electrical shock dangers and equipment injury.
