Description

Technical Field

[0001] The utility model relates to the field of switches, in particular to a guide rail type intelligent composite switch. Background Art

[0002] The guide rail type intelligent compound switch is an intelligent low-voltage capacitor switching switch, which combines the advantages of thyristors and contactors. By connecting thyristors and magnetic latching relays in parallel, the functions of voltage zero-crossing conduction and current zero-crossing cutoff are realized. This switch has the advantages of zero-crossing switching of thyristors at the moment of connection and disconnection, and has the advantage of no power consumption of contactor switches during normal connection. The design of the guide rail type intelligent compound switch aims to make up for the shortcomings of thyristors and AC contactors in low-voltage reactive power compensation applications, and provide a more efficient and energy-saving solution. Its working principle not only ensures that zero-crossing switching can be achieved at the moment of switching, thereby reducing the problems of inrush current and contact sintering, but also has multiple protection functions such as voltage anomaly protection, phase loss protection, no-load protection, component failure protection, operation indication, etc., to ensure the safe and reliable operation of the equipment. The Chinese patent discloses a guide rail mounted intelligent compound switch (authorization announcement number CN 216720539U), this patented technology can ensure the stable and convenient installation of the intelligent composite switch, while facilitating disassembly and maintenance, and is suitable for installation inside a narrow distribution box, bringing great convenience to people's later replacement and maintenance. By setting the blocking rod and fixed column, the limit column and the elastic lever, the distance when the sliding frame moves downward is limited, and the sliding frame will not continue to move downward to cause the sliding frame to detach from the back of the card switch. The structural design is reasonable, and the reset spring provided can be more effectively reset after the sliding frame moves, thereby facilitating the fixed connection during the installation of the switch, improving the reliability of the switch on the guide rail, and achieving the desired effect. However, the guide rail structure of this design is not good, and the ball linear structure is not adopted, resulting in a high friction coefficient, easy wear, and reduced service life. Therefore, those skilled in the art provide a guide rail type intelligent composite switch to solve the problems raised in the above background technology. Utility Model Content
