HXFK0.25-45A主要應(yīng)用于工業(yè)配電系統(tǒng)、商業(yè)建筑及公共設(shè)施的節(jié)能改造項(xiàng)目。在紡織機(jī)械、注塑設(shè)備、電梯等存在快速負(fù)載變化的場(chǎng)景中，能有效改善功率因數(shù)，降低線路損耗。其無(wú)噪聲運(yùn)行特性使其特別適合醫(yī)院、學(xué)校等對(duì)環(huán)境要求較高的場(chǎng)所。產(chǎn)品通過(guò)簡(jiǎn)化接線設(shè)計(jì)和拔插式接口，提高了安裝效率，縮短了現(xiàn)場(chǎng)施工時(shí)間。162127

英文介紹

The HXFK0.25-45A hybrid switching device is an electromechanical integrated solution for capacitor bank control in low-voltage reactive power compensation systems. Operating at 50Hz-60Hz with rated voltage of 220V/380V, this three-phase device adopts star-connected topology (3Y type) supporting 10kVar compensation capacity. Its zero-crossing switching technology combines thyristor s rapid response and relay s energy-efficient operation, achieving seamless engagement under voltage zero-point and disengagement at current zero-crossing.36

Key features include microprocessor-based intelligent monitoring with comprehensive protection against phase loss, under-voltage and self-diagnosed faults. The magnetically held relay mechanism ensures ≤1.5VA power consumption during operation while maintaining contact resistance below 0.01Ω. With compact dimensions (110×150×98mm) and pluggable terminals, the switch facilitates easy integration into existing panels. The photoelectric isolation design enhances EMI resistance, making it suitable for harsh industrial environments with significant harmonic disturbances.101525

This product finds wide applications in manufacturing facilities, commercial complexes and infrastructure projects requiring dynamic power factor correction. Its noiseless operation and independent phase control capability address challenges in unbalanced load conditions. The maintenance-free design eliminates need for cooling accessories, reducing lifecycle costs. Simplified wiring architecture with color-coded terminals minimizes installation errors and commissioning time.162127
