電容器BSMJ0.4-20-3
產(chǎn)品概述(中英文)
BSMJ0.4-20-3型自愈式低壓并聯(lián)電容器是一種專為電力系統(tǒng)無功補(bǔ)償設(shè)計的節(jié)能設(shè)備,適用于額定電壓400V、頻率50Hz的三相交流電網(wǎng)。該產(chǎn)品采用金屬化聚丙烯薄膜作為介質(zhì)材料,具有體積小、重量輕的特點(diǎn),重量僅為傳統(tǒng)油浸式電容器的1/4至1/5,便于安裝與維護(hù)。其核心功能是通過補(bǔ)償感性無功功率,提高電網(wǎng)功率因數(shù),降低線路損耗,從而優(yōu)化電能質(zhì)量并減少能源浪費(fèi)。
The BSMJ0.4-20-3 self-healing low-voltage shunt capacitor is an energy-saving device designed for reactive power compensation in power systems, suitable for three-phase AC grids with a rated voltage of 400V and frequency of 50Hz. Utilizing metallized polypropylene film as the dielectric material, this product features compact size and lightweight design, weighing only 1/4 to 1/5 of traditional oil-immersed capacitors, facilitating installation and maintenance. Its primary function is to improve power factor by compensating inductive reactive power, thereby reducing line losses and optimizing power quality.
技術(shù)特點(diǎn)(中英文)
BSMJ0.4-20-3電容器具備優(yōu)異的自愈性能,當(dāng)介質(zhì)因過電壓發(fā)生局部擊穿時,可自動恢復(fù)絕緣性能,提升運(yùn)行可靠性。內(nèi)置放電電阻和安全保護(hù)裝置,斷電后能在3分鐘內(nèi)將殘余電壓降至50V以下,同時可在故障時快速切斷電源,防止事故擴(kuò)大。其損耗角正切值低于0.1%,發(fā)熱量小,溫升低,有助于延長使用壽命。產(chǎn)品設(shè)計考慮了散熱需求,建議安裝間距大于30mm,適用于干燥通風(fēng)的室內(nèi)環(huán)境。
The BSMJ0.4-20-3 capacitor exhibits excellent self-healing properties, automatically restoring insulation performance in case of partial breakdown due to overvoltage. Equipped with built-in discharge resistors and safety protection devices, it can reduce residual voltage to below 50V within 3 minutes after power-off and quickly disconnect in case of internal faults. With a loss tangent value below 0.1%, it generates minimal heat and maintains low temperature rise, contributing to extended service life. The design incorporates thermal management considerations, recommending an installation spacing of over 30mm in dry, well-ventilated indoor environments.
應(yīng)用場景(中英文)
該電容器廣泛應(yīng)用于工業(yè)與民用低壓配電系統(tǒng),特別適合石油、冶金、水泥等存在電壓波動的行業(yè)。在電力系統(tǒng)中,它可與電抗器配合使用以抑制諧波影響,但需避免頻繁投切(間隔時間需超過3分鐘)。典型應(yīng)用場景包括工廠配電房、商業(yè)建筑配電柜及新能源發(fā)電并網(wǎng)系統(tǒng),能有效提升電網(wǎng)穩(wěn)定性與經(jīng)濟(jì)性。
This capacitor is widely used in industrial and civil low-voltage distribution systems, particularly in industries with voltage fluctuations such as petroleum, metallurgy, and cement. In power systems, it can be paired with reactors to mitigate harmonic effects, though frequent switching (intervals exceeding 3 minutes) should be avoided. Typical applications include factory power distribution rooms, commercial building switchgear, and renewable energy grid integration systems, effectively enhancing grid stability and operational efficiency. 15622
