FMGa標(biāo)準(zhǔn)互感器/FMGa
產(chǎn)品概述
FMGa標(biāo)準(zhǔn)互感器是一種采用雙線并繞空心線圈設(shè)計(jì)的精密電磁測量設(shè)備，適用于直流和低頻電磁測量場景，同時(shí)可與沖擊電流計(jì)配套使用。該產(chǎn)品在高校實(shí)驗(yàn)教學(xué)中廣泛作為標(biāo)準(zhǔn)器件或被測器件，能夠滿足教學(xué)與科研的雙重需求。FMGa提供陶瓷骨架和塑料骨架兩種款式，用戶可根據(jù)實(shí)際應(yīng)用環(huán)境靈活選擇，制造商還支持定制化需求，以適應(yīng)特殊測量場景。1
技術(shù)特點(diǎn)
FMGa標(biāo)準(zhǔn)互感器在設(shè)計(jì)和性能上具有顯著優(yōu)勢。其空心線圈結(jié)構(gòu)確保了良好的線性度和低磁滯損耗，適用于高精度測量。產(chǎn)品工作頻率范圍為1000±20Hz，環(huán)境溫度需保持在20±2℃以確保最佳性能�；ジ衅鞑捎眉t、黑雙色接線柱區(qū)分同名端，簡化了安裝流程。此外，其絕緣電阻超過100MΩ，耐壓能力達(dá)500V/50Hz，保障了長期穩(wěn)定性和安全性。需要注意的是，使用時(shí)應(yīng)避免靠近鐵磁性物質(zhì)，且連續(xù)工作時(shí)間不宜超過2小時(shí)。2
應(yīng)用場景
FMGa標(biāo)準(zhǔn)互感器主要應(yīng)用于三大領(lǐng)域：一是電力系統(tǒng)的電流監(jiān)測與保護(hù)，配合儀表實(shí)現(xiàn)精準(zhǔn)測量；二是實(shí)驗(yàn)室環(huán)境下的電磁特性研究，如磁通量測量或電路參數(shù)標(biāo)定；三是工業(yè)自動化場景中的信號轉(zhuǎn)換與隔離。其輕量化設(shè)計(jì)和緊湊結(jié)構(gòu)（典型尺寸14×14×10cm）使其易于集成到各類設(shè)備中。制造商強(qiáng)調(diào)產(chǎn)品的環(huán)境適應(yīng)性，建議在5~40℃的干燥環(huán)境中存放以延長使用壽命。4
Product Overview
The FMGa standard mutual inductor features a bifilar-wound air-core coil design, serving as a precision electromagnetic measurement device for DC and low-frequency applications. Compatible with ballistic galvanometers, it functions both as a reference component and test subject in university laboratories. Available in ceramic or plastic frame versions, the product supports customized configurations to address specialized measurement requirements. Its open-core structure ensures minimal interference from external magnetic fields.1
Technical Specifications
Engineered for reliability, the FMGa exhibits excellent linearity with a typical deviation of ≤0.2%. The dual-color coded terminals (red/black) facilitate correct polarity identification during installation. Operational parameters include a working frequency of 1000±20Hz and ambient temperature range of 20±2℃ for optimal performance. The epoxy-encapsulated windings provide robust insulation (>100MΩ) and withstand 500V AC for 1 minute. Users should maintain a minimum clearance of 30cm from ferromagnetic materials during operation. The lightweight construction (1.7kg) enables flexible deployment across different experimental setups.2
Applications
Widely adopted in three primary domains: power system current monitoring (paired with measuring instruments), laboratory electromagnetic research (flux measurement/circuit calibration), and industrial signal conditioning systems. The compact form factor (Φ15×160mm max) allows seamless integration into switchgear cabinets or test benches. For prolonged storage, manufacturers recommend moisture-proof packaging in controlled environments (relative humidity 40-80%). The product s consistent performance makes it suitable for comparative studies requiring repeatable measurement conditions.4
