Description

Technical Field

[0001] This utility model relates to the field of electrical component technology, and in particular to a combined voltage transformer. Background Technology

[0002] A combined voltage transformer is a special electrical device that combines a voltage transformer and a current transformer. It is used to measure the voltage and current on high-voltage transmission lines. When a power system fault occurs, the combined transformer can provide current and voltage information in a timely manner, helping to quickly locate the fault point and take corresponding protective measures to prevent the fault from escalating. Therefore, combined voltage transformers are needed. However, traditional combined voltage transformers have a relatively simple design structure, which makes the disassembly process of the terminals cumbersome. At the same time, it is not convenient to disassemble the transformer casing to perform internal maintenance. The inconvenient terminals may increase the difficulty of operation during maintenance and repair, thereby increasing the safety hazards such as electric shock and short circuits. Due to the inconvenience of disassembly by design, the disassembly process of the transformer casing may become extremely complicated and require a lot of time and manpower. Utility Model Content

[0040] By setting the slide rod 108c, it is easy to connect the rotating shaft 108b. By setting the sleeve rod 108d, it is easy to slide the slide rod 108c. It should be noted that the sleeve rod 108d is equipped with a spring for resetting the slide rod 108c.

[0041] Specifically, the reset component 108 also includes a rotating column 108e and a fixed seat 108f. The rotating column 108e rotates on the inner wall of the sleeve rod 108d, and the fixed seat 108f is fixed to the inner wall of the lower housing 101.

[0042] By setting the rotating column 108e, the sleeve rod 108d can be rotated easily; by setting the fixed seat 108f, the rotating column 108e can be rotated easily.

[0043] Specifically, the wiring component 109 includes a wiring plate 109a and a slot 109b. The wiring plate 109a is disposed at the bottom of the lower housing 101, and the slot 109b is formed on the inner wall of the wiring plate 109a.

[0044] The junction box 109a facilitates the connection of wires, and the slot 109b facilitates the passage of wires. Example

[0045] Reference Figure 5 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0046] Specifically, the limiting member 205 includes a first connecting shaft 205a and a second connecting shaft 205b. The first connecting shaft 205a rotates on the inner wall of the connecting seat 203, and the second connecting shaft 205b rotates on the inner wall of the connecting rod 204.

[0047] By setting the first connecting shaft 205a, it is easy to connect the connecting rod 204; by setting the second connecting shaft 205b, it is easy to connect the moving block 205c.

[0048] Specifically, the limiting member 205 also includes a moving block 205c and a sliding column 205d. The moving block 205c rotates on the outside of the second connecting shaft 205b, and the sliding column 205d slides on the inner wall of the moving block 205c.

[0049] By setting the movable block 205c, the connecting rod 204 can be easily driven. By setting the sliding column 205d, the movable block 205c can be easily slid. It should be noted that a spring for resetting the movable block 205c is provided on the outside of the sliding column 205d.

[0050] Specifically, the mounting component 206 includes a mounting plate 206a and a fixing plate 206b.

[0051] The mounting plate 206a facilitates the fixing of the sliding column 205d, and the fixing plate 206b facilitates the fixing of the mounting plate 206a.

[0052] When it is necessary to disassemble the terminal block 201, move the limiting ring 202 away from the axis of the terminal block 201. Since the moving block 205c slides outside the sliding column 205d, the moving block 205c connects to the second connecting shaft 205b, the second connecting shaft 205b connects to the connecting rod 204, the connecting rod 204 connects to the first connecting shaft 205a, the first connecting shaft 205a connects to the connecting seat 203, and the connecting seat 203 connects to the limiting ring 202. This allows the limiting ring 202 to be moved, thereby disassembling the terminal block 201. Simultaneously, when it is necessary to disassemble the lower housing... When disassembling 101 and the upper housing 102, lift the snap-fit ​​block 105, and then lift the slide rod 108c. Rotate the slide rod 108c and the sleeve rod 108d upwards around the rotating column 108e, thereby driving the connecting rod 108a to move. The movement of the connecting rod 108a drives the rotating rod 107c to rotate, thereby driving the mounting plate 107a to move downwards around the rotating rod 107c, thereby driving the mounting block 106 to move, and then moving the snap-fit ​​block 105. After disassembling the lower housing 101 and the upper housing 102, perform internal repairs.

[0053] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
