This type of low-voltage transformer is generally directly fixed on the inner wall of the transformer box with screws. The existing transformer box can only open the front door, the space is narrow, and the fixing screws are all inside the transformer box, which is very inconvenient to install and disassemble, which seriously affects the work efficiency.

Utility model content

The purpose of the utility model is to provide a low-voltage current transformer, which can be easily installed with the box body, so as to improve the working efficiency of installation and disassembly.

The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a low-voltage current transformer, including a transformer body and a box for installing the transformer body, and the box is built with four symmetrically arranged Fixed brackets, one side of each fixed bracket is fixedly connected with the inner wall of the box, wherein a slide bar is connected between the two fixed brackets, and the same sliding rod as above is connected between the other two fixed brackets. The two sliding rods are arranged parallel to each other, and the two sliding rods are sleeved with the same fixed seat that can move along the axial direction of the sliding bar; the middle part of the fixed seat is pierced with a screw rod, Both ends of the screw are sleeved with bearing seats, one end of each bearing seat is fixedly connected to the inner wall of the box, and one end of the screw goes out of the box to be provided with a screw that can be driven to rotate forward or For a reverse drive motor, the upper end of the fixing base is provided with a transformer body.

The utility model is further configured as follows: the upper end of the fixing base is provided with a mounting frame, the mounting frame is provided with a transformer mounting hole, and the transformer body is mounted on the mounting frame through the transformer mounting hole.

The utility model is further configured as follows: one side of the box body is hingedly provided with a box door, and a transparent observation window is set on the box door.

In summary, the utility model has the following beneficial effects: simple structure, easy to use, technicians can adjust the position of the transformer body by driving the motor, so as to facilitate the installation and removal of the current transformer, save time and effort, and greatly improve the work efficiency.

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail.

This specific embodiment is only an explanation of the utility model, and it is not a limitation of the utility model. After reading this description, those skilled in the art can make modifications to the embodiment without creative contribution according to needs, but as long as it is within the utility model All new claims are protected by patent law.

As shown in FIG. 1 , FIG. 2 and FIG. 3 , a low-voltage current transformer includes a transformer body 1 and a box body 2 for installing the transformer body 1 . One side of the box body 2 is hingedly provided with a box door 3 , and a transparent observation window 4 is arranged on the box door 3 to facilitate observation of the operation status of the transformer body 1 in the box body 2 .

The box body 2 is built with four fixed brackets 5 arranged symmetrically to each other, and one side of each fixed bracket 5 is fixedly connected with the inner wall of the box body 2 . A slide bar 6 is connected between the two fixed brackets 5, and the same slide bar 6 as above is connected between the other two fixed brackets 5, and the two slide bars 6 are arranged parallel to each other. The two sliding rods 6 are sleeved with the same fixed seat 7 that can move along the axial direction of the sliding rods 6 . The middle part of the fixing seat 7 is provided with a screw mandrel 8, and the two ends of the screw mandrel 8 are sleeved with bearing seats 9, and one end of each bearing seat 9 is fixedly connected with the inner wall of the box body 2. In particular, one end of the threaded mandrel 8 passes out of the box body 2 and is provided with a driving motor 10 capable of driving the threaded mandrel 8 to rotate forward or reversely. The upper end of the fixing seat 7 is provided with a mounting frame 11 , and the mounting frame 11 is provided with a transformer mounting hole 12 , and the transformer body 1 is mounted on the mounting frame 11 through the transformer mounting hole 12 .

A technician can drive the motor 10 by opening and closing, thereby causing the screw mandrel 8 to rotate. At this time, the screw mandrel 8 rotates in a certain direction so that the fixing seat 7 cooperating with the screw mandrel 8 rotates synchronously. Since the fixed seat 7 cooperates with the slide bars 6 on both sides, the fixed seat 7 cannot rotate, and then the fixed seat 7 can move along the direction of the axis of the screw mandrel 8 . Furthermore, the installation frame 11 connected with the fixing seat 7 can be moved to a desired position, so that technicians can install the transformer body 1 on the installation frame 11 . After the installation is completed, the technician drives the motor 10 to reverse the screw mandrel 8 to drive the screw mandrel 8 to reverse, so that the above-mentioned fixing seat 7 moves to the inside of the box body 2, so that the transformer body 1 is located inside the box body 2 .

Through the above-mentioned structural design, the structure is simple and easy to use, and the installation and disassembly of the transformer body 1 is relatively convenient, saving time and effort, and greatly improving work efficiency.
