BSMJ Series Single Phase Power Factor Capacitor

In the vertical transportation system of modern buildings, the stable and energy-efficient operation of elevators is of utmost importance. However, the frequent start-stop and heavy load impact characteristics of single-phase elevator motors pose severe challenges to reactive power compensation devices. The BSMJ Series Single Phase Power Factor Capacitors developed by Geyue Electric are precisely designed to address such scenarios. The secret behind their outstanding performance lies in the deep integration of multiple core technologies and scenario-specific innovations.

The Art of Compensation for Precisely Matching Dynamic Loads

The essence of elevator operation is a typical intermittent impact load, which profoundly affects its power quality and energy consumption performance. The drive motor of the elevator requires a large amount of reactive power to establish the magnetic field at the moment of startup, which often leads to voltage drops and energy waste. In the face of such complex conditions, Geyue Electric's BSMJ Series Single Phase Power Factor Capacitors, with their rapid response characteristics and shock-resistant design, can precisely compensate for reactive power within a short period of time. They do not simply perform fixed compensation; instead, they precisely inject the reactive power required by the motor within milliseconds, effectively mitigating the startup shock of the motor. More importantly, for the grid imbalance problem caused by single-phase elevators, BSMJ Series Single Phase Power Factor Capacitors can perform targeted single-phase compensation, avoiding the awkward situation of "under compensation" or "over compensation" in the traditional three-phase compensation scheme, and maximizing the efficiency of reactive power compensation.

Resilient and Durable Reliability Engineering

The electrical environment in the elevator machine room is so complex that it places extremely high demands on the reliability of the reactive power compensation equipment. Geyue Electric’s BSMJ Series Single Phase Power Factor Capacitors adopt metallized polypropylene film and self-healing technology. When the medium experiences voltage fluctuations, harmonic impacts, or manufacturing micro-defects resulting in minor local breakdown, the metallized electrodes can instantly vaporize to achieve insulation isolation. The evaporated metal layer around the breakdown point quickly oxidizes to form a new insulating boundary, thereby achieving automatic repair of the fault point and ensuring uninterrupted continuous operation. The unique thickened edge metallized film and new gold spraying technology endow BSMJ series with strong anti-inrush-current capability sufficient to handle the current impact caused by the frequent start-stop of elevators. In addition, the built-in safety device and discharge resistor together build a dual active safety barrier: when the system encounters abnormal overcurrent caused by short circuits, harmonic amplification, or internal faults of the capacitor, the special alloy fuse can precisely melt within milliseconds, completely isolating the faulty unit and completely eliminating potential safety hazards for maintenance personnel, achieving a full closed-loop guarantee from operation to maintenance. These safety protection designs enable BSMJ series to demonstrate far greater durability in the long-term operation of elevators compared to ordinary reactive power compensation components.

Significant Energy-Saving and System Optimization Value

The outstanding performance of Geyue Electric’s BSMJ Series Single Phase Power Factor Capacitors in elevator scenarios can directly translate into considerable economic benefits. They increase the power factor of elevator motors from the usual 0.7-0.8 to above 0.95, significantly reducing the reactive current and transmission losses in the lines. For elevators that start and stop hundreds of times a day, BSMJ series mean considerable annual electricity cost savings. At the same time, stable voltage support given by BSMJ series capacitors reduces motor temperature rise and torque fluctuations, not only enhancing passenger comfort but also helping to extend the service life of key equipment such as motors and frequency converters. From the perspective of power distribution, the reactive power compensation provided by the BSMJ series capacitors has released the capacity of the transformer, providing valuable space for the subsequent expansion of the building's power system.

The outstanding performances of the BSMJ Series Single Phase Power Factor Capacitors in single-phase elevator systems merely represents a microcosm of Geyue Electric's deep commitment to the field of low-voltage reactive power. We are well aware that true value lies not in the performance parameters of a single product, but in the adaptability and systematic contribution of product combinations to complex on-site conditions. Geyue Electric has always been dedicated to integrating advanced materials science, electrical design, and digital intelligent control to provide customers with comprehensive low-voltage reactive power compensation solutions from precise components to complete systems, from hardware configuration to intelligent management. We not only offer products, but also provide energy efficiency improvement paths based on a deep understanding of scenarios, helping commercial buildings, industrial plants, public facilities, and various electrical users achieve fundamental optimization of power quality and sustainable reduction of energy costs.
