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.
技术特点(中英文)
BSMJ0.4-20-3电容器具备优异的自愈性能,当介质因过电压发生局部击穿时,可自动恢复绝缘性能,提升运行可靠性。内置放电电阻和安全保护装置,断电后能在3分钟内将残余电压降至50V以下,同时可在故障时快速切断电源,防止事故扩大。其损耗角正切值低于0.1%,发热量小,温升低,有助于延长使用寿命。产品设计考虑了散热需求,建议安装间距大于30mm,适用于干燥通风的室内环境。
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.
应用场景(中英文)
该电容器广泛应用于工业与民用低压配电系统,特别适合石油、冶金、水泥等存在电压波动的行业。在电力系统中,它可与电抗器配合使用以抑制谐波影响,但需避免频繁投切(间隔时间需超过3分钟)。典型应用场景包括工厂配电房、商业建筑配电柜及新能源发电并网系统,能有效提升电网稳定性与经济性。
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
