Description

Technical Field

[0001] This utility model relates to the field of fuse application technology, specifically a high-voltage fuse based on power transmission. Background Technology

[0002] High-voltage fuses are key protective devices in power systems, used to prevent damage caused by circuit overload and short circuit. In the process of power transmission, high-voltage fuses play a vital role, as they can quickly disconnect faulty circuits and protect electrical equipment from damage caused by overload and short circuit currents.

[0003] However, traditional high-voltage fuses have some problems in use. For example, the assembly process is cumbersome, the sealing performance is poor, and water leakage can easily lead to leakage and short circuits. With the increasing complexity of the power grid and technological advancements, the performance requirements for high-voltage fuses are also getting higher and higher. Traditional fuses may not be able to meet the high reliability and intelligence requirements of modern power systems. Therefore, a high-voltage fuse based on power transmission has been proposed. Utility Model Content

[0004] The purpose of this invention is to provide a high-voltage fuse based on power transmission to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a high-voltage fuse based on power transmission, comprising a rear mounting plate, an insulating pad, a fuse housing, and a fuse breaking assembly; the insulating pad is fixed to the front surface of the rear mounting plate, and the fuse housing is mounted on the front surface of the insulating pad. The insulating pad effectively isolates the direct electrical contact between the rear mounting plate and the fuse housing, enhancing the safety performance of the equipment and preventing the risk of short circuits or electric shocks caused by electrical faults; moreover, the insulating pad, as a supporting structure, provides a stable mounting base for the fuse housing, helping to maintain the stability and reliability of the fuse and extend its service life. A touch display is nested on the front surface of the fuse housing, allowing users to intuitively view the working status of the fuse, including key parameters such as current and voltage, as well as fault alarm information, improving the ease of operation and safety of the equipment; simultaneously, the touch display also has an operating interface, allowing users to interact with the fuse via touch... The touchscreen allows for parameter settings and troubleshooting, further enhancing the equipment's intelligence. A fuse disconnect component is mounted on the front surface of the fuse housing. As the core component of the fuse, this component quickly cuts off the circuit in case of overload or short circuit, effectively protecting the safe and stable operation of the power transmission system. This component features a high-reliability design, ensuring normal operation even under extreme conditions, providing strong protection for the power system's safety. The fuse disconnect component is located directly below the touchscreen display. Cable connection slots are installed at both the top and bottom of the fuse housing. These slots facilitate connection between the fuse and external circuits, ensuring the stability and efficiency of current transmission. Users can easily connect the fuse to the power transmission system via the cable connection slots, enabling quick installation and removal, improving equipment maintenance convenience. Furthermore, the cable connection slots are designed with an anti-loosening structure, effectively preventing electrical faults caused by loose connections, further enhancing the equipment's safety performance.

[0006] Preferably, a rectangular fixing plate is fixed to the rear mounting plate by tightening screws, and the tightening screws are set in tightening and fixing grooves opened in the rectangular fixing plate. A tightening semi-circular hanging plate is welded to the top of the rectangular fixing plate. The design of the tightening semi-circular hanging plate not only enhances the structural strength of the rectangular fixing plate, but also provides convenience for the installation of the equipment. Users can easily hang the fuse in the designated installation position by tightening the semi-circular hanging plate, without complicated installation steps, which greatly improves the installation efficiency. At the same time, the welded connection between the tightening semi-circular hanging plate and the rectangular fixing plate ensures the firmness and stability of the connection, effectively avoiding equipment falling off or being damaged due to unstable mounting, and further improving the safety performance of the equipment. In addition, the cooperation between the tightening screws and the tightening fixing grooves allows the rectangular fixing plate to be tightly fixed to the rear mounting plate, which not only enhances the overall structural strength of the equipment, but also provides a strong guarantee for the stable operation of the equipment.

[0007] Preferably, the fuse disconnect assembly is provided with an anti-electric shock guide seat, on which an automatic disconnect rod is installed. An anti-electric shock grip is installed on the top of the automatic disconnect rod. The design of the anti-electric shock guide seat cleverly guides the operator to operate safely in emergency situations. When an overload or short circuit occurs in the circuit, the fuse disconnect assembly will respond quickly, automatically disconnecting the circuit through the automatic disconnect rod, thereby effectively preventing equipment damage or even fire accidents caused by excessive current. The anti-electric shock grip further enhances the safety of the operator when disconnecting the circuit, effectively avoiding the risk of electric shock caused by direct contact with high-voltage circuits. Simultaneously, the synergistic effect of the anti-electric shock guide seat, automatic disconnect rod, and anti-electric shock grip makes the operation of the fuse simpler and faster, greatly improving the reliability and practicality of the equipment.

[0008] Preferably, the front surface of the fuse housing is provided with mounting grooves at both the upper and lower ends, and tightening screws are installed in the mounting grooves. The design of the tightening screws not only ensures the stable installation of the fuse housing, but also facilitates later maintenance and replacement. During the installation process, the operator only needs to place the fuse housing in the predetermined position, and then tighten the screws to firmly fix the housing in the mounting groove, which can realize the rapid installation of the fuse. This design not only simplifies the installation steps, but also improves the installation efficiency. At the same time, the tightening effect of the screws effectively prevents the fuse from loosening due to vibration or external force during operation, thereby ensuring the stable operation of the fuse. In addition, the material and surface treatment process of the tightening screws have been carefully selected to ensure that they have good corrosion resistance and wear resistance, further extending the service life of the fuse.

[0009] Preferably, an anti-electric shock film is provided on the outer surface of the fuse housing. The anti-electric shock film further enhances the safety performance of the fuse and effectively prevents the risk of electric shock caused by accidental contact with high-voltage components when the operator repairs or replaces the fuse. This innovative design not only enhances the safety of the fuse but also reflects a deep concern for user safety. Furthermore, the fuse disconnection component is electrically connected to the touch screen, which allows the fuse's operating status to be displayed on the touch screen in real time. The operator can intuitively view information such as the fuse's operating voltage, current, and whether it is in a normal fuse-breaking state, thereby enabling a rapid response and handling of any abnormal situation. This intelligent design not only improves the monitoring efficiency of the fuse but also provides a strong guarantee for the stable operation of the power system.
