Description

Technical Field

[0001] The invention relates to the technical field of transformer protection, and in particular to a transformer with a protection structure. Background Art

[0002] A step-down transformer is a device that uses the principle of electromagnetic induction to change voltage. It is mainly composed of a primary coil, a pole coil and an iron core. It is widely used in power grid systems. When transmitting electricity, a step-up transformer is often used in power plants to increase the voltage of the generated electricity to a certain level, and then it is transmitted to the municipal power network and then a step-down transformer is used to reduce the voltage to 220V or 380V for use.

[0003] Application No. CN202311585345.3 The present invention discloses a transformer group with an external protection structure, including a transformer housing fixedly installed on the ground by screws, two groups of transformer coils with different numbers of turns are fixedly installed inside the transformer housing, and the upper surface of the transformer housing is fixedly installed with a terminal block connected to an external line; a data collector is fixedly installed inside the transformer housing. The transformer group with an external protection structure adopts a new structural design, so that the device uses the external protection plate added to the outside of the transformer housing to further protect it during use, and the external protection plate has a buffer structure to buffer the impact, so as to achieve better protection. When the temperature inside the transformer housing rises due to a short circuit, the hot melt rope melts, so that the movable plate moves downward by its own gravity, so that the upper contact piece and the lower contact piece are separated from each other, thereby disconnecting the overall circuit and reducing subsequent losses and dangers.

[0004] Based on the search of the above patents and the application of existing transformers with protective structures: At present, when a protective structure is added to a transformer, it indirectly affects the overall heat dissipation effect of the transformer, which is easy to interfere with the operation of the transformer and affect its service life.

[0005] Therefore, in view of this, research and improvement are conducted on the existing structure and defects, and a transformer with a protective structure is provided, in order to achieve a more practical purpose. Summary of the invention

[0006] In order to solve the above technical problems, the present invention provides a transformer with a protective structure to solve the existing problem that when the protective structure is added to the transformer, the overall heat dissipation effect of the transformer is indirectly affected, which easily interferes with the operation of the transformer and affects its service life.

[0007] The present invention provides a transformer with a protective structure, which specifically includes: a support base; a transformer body is installed at the middle position of the top of the support base, a rear plate designed in a U shape is fixedly connected to the rear end position of the top of the support base, a lifting frame is fixedly connected to the upper position inside the rear plate, a lifting block is slidably connected to the front end position of the lifting frame, a limiting frame is fixedly connected to the front end position of the lifting block, a track is respectively arranged on the left and right sides of the top of the limiting frame, the two tracks are symmetrically designed, a slider is slidably connected to the top position of each track, a Z-shaped rod is rotatably connected to the upper position inside each slider, the two sliders are symmetrically designed, the two Z-shaped rods are symmetrically designed, a reversing member is fixedly connected to the left and right sides of the top of the limiting frame, the two reversing members are symmetrically designed, and the two reversing members are respectively located outside the two tracks, L-shaped reversing grooves are opened at the upper side positions of the sides of the two reversing members, and the outer sides of the two Z-shaped rods are located in the reversing grooves on the sides of one reversing member.

[0008] Furthermore, a pulley frame is respectively fixedly installed on the left and right sides of the bottom of the support base, and two universal wheels are arranged at the bottom position of each pulley frame.

[0010] Furthermore, a positioning frame is symmetrically fixedly connected to the two sides of the front end of the top of the limiting frame, and the two positioning frames are respectively located directly in front of one track.

[0011] Furthermore, a telescopic member is fixedly connected to each positioning frame, the telescopic member is located directly in front of the slider, and the position of the telescopic rod of the telescopic member is fixedly connected to the middle position of the front end of the slider, and the telescopic member is equipped with a controller itself.

[0012] Furthermore, the inner sides of the two Z-shaped rods and the left and right sides of a sealing plate, the sealing plate is fixedly connected to a transparent plate, and the sealing plate and the transparent plate are designed in a perpendicular manner to jointly form an L shape, and a through strip-shaped groove is opened in the transparent plate.

[0013] Furthermore, when the telescopic member is in a contracted state, the slider is located at the front end position of the track, the outer side position of the Z-shaped rod is located at the upper position inside the L-shaped reversing groove of the reversing member, and the transparent plate is located directly above the transformer body.

The shaft of the motor 104 is located in the threaded hole of the lifting block 105. A positioning frame 303 is symmetrically fixedly connected to the two sides of the top front end of the limit frame 3. The two positioning frames 303 are respectively located in front of a track 301. Each positioning frame 303 is fixedly connected with a telescopic member 304. The telescopic member 304 is located in front of the slider 302, and the telescopic rod position of the telescopic member 304 is fixedly connected to the middle position of the front end of the slider 302.
