Description

Technical Field

[0001] This utility model relates to the field of voltage transformers, and in particular to an electromagnetic voltage transformer with a fuse. Background Technology

[0002] Electromagnetic voltage transformers typically require fuses during application. The primary function of the fuse is to prevent damage to the high-voltage transmission system due to faults in the electromagnetic voltage transformer itself. Simultaneously, when a system fault causes overvoltage or overcurrent, the fuse will melt, thus taking the electromagnetic voltage transformer out of service and preventing damage. Usually, in the design, the fuse is installed at the front end of the voltage transformer and connected to the equipment via wires. Furthermore, the horizontal installation of the fuse requires support from insulators to ensure its stability and safety, making installation quite cumbersome. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an electromagnetic voltage transformer with a fuse that is convenient for fuse installation.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: an electromagnetic voltage transformer with a fuse, the innovation of which is: including An electromagnetic voltage transformer body is provided, with an oil tank connected to the bottom of the electromagnetic voltage transformer body and an expander connected to the top of the electromagnetic voltage transformer body. A fuse is installed above an expansion joint. The fuse is connected to the expansion joint through a bracket and a mounting flange. The bracket is a hollow cuboid bracket that covers the entire expansion joint and is fixed to it. The bottom end of the fuse is fixed to the upper surface of the bracket through the mounting flange.

[0005] Furthermore, the fuse is mounted vertically on the bracket.

[0006] Furthermore, a primary and secondary cable outlet box is also provided on the upper side of the oil tank.

[0007] The advantages of this utility model are as follows: In this utility model, the installation of the fuse is achieved by adding a bracket on the outside of the expander, which makes the installation of the fuse more convenient. At the same time, it eliminates the need for the support insulator required by traditional fuses, effectively reducing production costs.

[0008] In addition, by vertically mounting the fuses on the bracket, it is easier for staff to inspect and maintain them, thus improving the reliability and safety of the equipment.

[0009] Moreover, based on this directional approach, subsequent lines can be directly connected to the voltage transformer via fuses, reducing connection points and lowering the risk of faults caused by poor contact. This design not only optimizes the installation method of fuses but also improves the overall performance of electromagnetic voltage transformers. Attached Figure Description
