The BSMJ0.4-12-3 is a three-phase self-healing low-voltage shunt power capacitor utilizing metallized polypropylene film dielectric. Designed for 380V/50Hz AC power systems, it features a compact structure with volume and weight reduced to 20%-25% of conventional models. The integrated discharge resistor ensures residual voltage drops below 50V within 3 minutes after power-off, while the built-in pressure-sensitive protection device provides fault isolation capability. Environmentally friendly microcrystalline wax impregnation technology eliminates leakage risks throughout service life. Typical applications include power factor correction in industrial plants and commercial buildings.416
技術(shù)特點(diǎn)
該電容器具備優(yōu)異的自愈性能，當(dāng)介質(zhì)局部因過(guò)電壓發(fā)生擊穿時(shí)能瞬間恢復(fù)絕緣特性，使產(chǎn)品可靠性顯著提升。損耗角正切值低于0.1%，自身能耗極低，工作溫升小，延長(zhǎng)了使用壽命。電氣參數(shù)方面，額定電壓400V，容量12kvar，容量允差范圍+10%，極間耐壓達(dá)2.15倍額定電壓（10秒測(cè)試）。產(chǎn)品適用于海拔2000米以下環(huán)境，工作溫度范圍-25℃至+50℃，濕度不超過(guò)85%。獨(dú)特的金屬化膜邊加厚工藝增強(qiáng)了抗涌流能力，允許在1.3倍額定電流下持續(xù)運(yùn)行。5822
Key technical features include outstanding self-recovery capability that automatically repairs dielectric breakdown spots, with tanδ loss below 0.1% for minimized energy consumption.

結(jié)構(gòu)設(shè)計(jì)
產(chǎn)品采用矩形金屬外殼結(jié)構(gòu)，標(biāo)準(zhǔn)三相三角形接法（△），內(nèi)部元件經(jīng)過(guò)200倍額定電流的老練處理以提高穩(wěn)定性。創(chuàng)新性的真空灌裝工藝確保浸漬劑均勻分布，配合特殊密封設(shè)計(jì)防止氧化。安裝時(shí)需保持豎直姿態(tài)，多臺(tái)并聯(lián)時(shí)間距需大于30mm以保證散熱效果，夏季高溫環(huán)境建議增加強(qiáng)制通風(fēng)措施。連接導(dǎo)線推薦采用截面積不小于4mm²的多股軟銅線，端子螺栓扭矩應(yīng)達(dá)到3N·m以確保接觸可靠性。外殼防護(hù)等級(jí)滿足常規(guī)室內(nèi)安裝要求，避免陽(yáng)光直射和雨雪侵蝕。61527
Structurally designed with rectangular metal enclosure and delta connection (△), the capacitor undergoes 200×In aging process for enhanced stability. Vacuum impregnation technology ensures uniform dielectric distribution, with special sealing against oxidation. Installation requires vertical orientation with ≥30mm clearance between multiple units. Recommended connection uses ≥4mm² stranded copper wires with terminal torque of 3N·m. The enclosure protection level suits standard indoor environments, avoiding direct sunlight and precipitation exposure.91728
應(yīng)用價(jià)值
在電力系統(tǒng)中使用時(shí)，能有效提高功率因數(shù)至0.95以上，降低線路無(wú)功損耗15%-30%，改善電壓波動(dòng)問(wèn)題。相較于傳統(tǒng)電容器，年運(yùn)行損耗減少約40%，配合自動(dòng)投切裝置可實(shí)現(xiàn)智能化節(jié)能管理。典型投資回報(bào)周期為8-12個(gè)月，長(zhǎng)期運(yùn)行可減輕變壓器負(fù)荷，釋放10%-15%的供電潛能。維護(hù)方面僅需定期檢查外殼是否變形、端子是否松動(dòng)等基礎(chǔ)項(xiàng)目，正常使用條件下設(shè)計(jì)壽命超過(guò)10萬(wàn)小時(shí)。1013[
