Description

Technical Field

[0001] The utility model relates to the technical field of voltage transformers, in particular to a voltage transformer that is easy to repair. Background Art

[0002] In a high-voltage power supply system, voltage transformers need to be installed in order to power measuring instruments and relay protection devices when converting voltage, or to protect valuable equipment, motors, and transformers in the line when a line fault occurs.

[0003] In the prior art, the patent document with announcement number CN221239498U proposes a voltage transformer for power supply, including a base, a shell provided on the top surface of the base, an adjustment device for facilitating fuse replacement, the mounting assembly is fixedly mounted on the top surface of the shell, the adjustment assembly is slidably connected to the mounting assembly, the bottom end of the shell is provided with an energized column, and the movable column is slidably connected to the adjustment assembly. The utility model provides a pressable movable column at the bottom end of the shell to install the shell in the installation groove. If the fuse needs to be replaced, the pressing column is pressed into the through hole to install the bottom end of the shell into the installation groove. When the movable column reaches the slide groove position, the second spring is used to pop out the movable column into the slide groove to install the shell. Otherwise, the pressing column is pressed to pop out the movable column from the slide groove, thereby realizing the disassembly of the shell, saving manpower.

The existing technology addresses this problem by installing a pressable movable post at the bottom of the housing and mounting the housing in a mounting slot. However, this also results in the cumbersome removal of the housing during use, making it inconvenient for staff to inspect and repair the interior. Utility Model Content

When it is necessary to inspect the interior of the voltage transformer, the lifting plate 17 can be toggled so that the lifting plate 17 drives the clamping column 18 to rise under the limit of the limiting slide rod 16 and the limiting spring 19, so that the protective shell 21 can be easily slid out of the interior of the limiting slot 12, thereby facilitating maintenance personnel to inspect the interior of the voltage transformer.

[0030] Example 2

[0031] like Figure 1-5As shown, on the basis of Example 1, the utility model provides a technical solution: preferably, the protective component includes a protective shell 21, the bottom end of the protective shell 21 is slidably connected to the inner wall of the limiting groove body 12, one side of the protective shell 21 is fixedly connected to an ear plate, the inner wall of the ear plate is movably connected to one end of the clamping column 18, the inductor component includes a connecting seat 23, the bottom surface of the connecting seat 23 is detachably connected to the outer surface of the support plate 11, the upper surface of the connecting seat 23 is detachably connected to the magnetic core iron ring 24, the top of the magnetic core iron ring 24 is provided with a circuit board 25, the connection end of the circuit board 25 is electrically connected to the insulating sleeve 22, and the bottom of the insulating sleeve 22 A mounting plate 26 is fixedly connected, and one side of the mounting plate 26 is fixedly connected to the outer surface of the protective plate 13.

During the process, the protective shell 21 can be used to protect the electronic components inside the voltage transformer, and the voltage transformer can change the voltage in the circuit through the cooperation of the insulating sleeve 22, the magnetic core iron ring 24 and the circuit board 25. When current passes through the high-voltage winding, a magnetic field will be generated in the magnetic core iron ring 24.
