Description

Technical Field

[0001] The present application relates to the technical field of transformers, and in particular to a transformer that facilitates phase switching. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil, and an iron core. Its primary functions include voltage conversion, current conversion, impedance conversion, isolation, and voltage regulation. Commutation refers to the process of alternating positive and negative current signals at a certain frequency. In power systems, commutation is a crucial step in the transmission of AC voltage and current between power equipment. When electrical energy needs to be transferred from one AC voltage level to another, commutation is required to convert the energy.

[0003] It is not easy to disassemble the protective cover of the phase-changing tap changer of the existing transformer. In the traditional structure, it is installed through threaded connection. However, after repeated rotation, tightening and disassembly, the thread of the threaded connection will easily slip, which will affect the tightness of the protective cover installation and the sealing after installation.

Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments.

[0028] Reference Figure 1-5 A transformer that is convenient for phase change includes a base 1, a transformer body 7 is fixedly installed on the top of the base 1, a fixing base 8 is installed on the top of the transformer body 7, a tap changer 9 is installed on the top of the fixing base 8, and five notches 10 are evenly distributed on the outer edge of the tap changer 9. Two holes 11 are symmetrically provided on the top of the fixing base 8, and two other round covers 12 are symmetrically fixedly installed on the outer edge of the fixing base 8. A latch 13 is slidably connected to the inner wall of the round cover 12, and a gasket 14 is slidably connected to the outer edge of the latch 13. One end of a return spring 15 is fixedly connected to the outer side of the gasket 14, and the other end of the return spring 15 is fixedly connected to the gasket 2 16. A slope 17 is provided on the end of the latch 13 near the gasket 2 16, and a protective cover 18 is installed on the top of the fixing base 8. Two positioning rods 19 are symmetrically fixedly installed on the bottom of the protective cover 18, and the inner walls of the two positioning rods 19 are penetrated by positioning holes 3.

[0029] See Figure 2 and Figure 5 A slide groove 4 is provided at the bottom of the base 1, and two sliders 5 are symmetrically slidably connected to the inner wall of the slide groove 4, and a fixing bar 6 is fixedly installed at the bottom of the two sliders 5. Two mounting holes are symmetrically provided on the inner walls of the two fixing bars 6, so that the sliding slider 5 can adjust the fixing bar 6 to different positions, and then it is convenient to match the bolts and the mounting holes to install the fixing bar 6 to different positions, thereby improving the convenience of the device during installation.

[0030] See Figure 3 and Figure 4 A pull plate 20 is fixedly installed at one end of the latch 13 away from the slope 17, and the second gasket 16 is fixedly installed on the outer edge of the latch 13. The first gasket 14, the return spring 15 and the second gasket 16 are all arranged in the inner cavity of the round cover 12. The pull plate 20 increases the convenience of the user pulling the latch 13 to adjust the position of the slope 17, which is convenient for the hand to exert force, and 26 can limit the latch 13, so that the latch 13 cannot be directly pulled out to the outside when the pull plate 20 is pulled.

[0031] See Figure 3 and Figure 4The two positioning rods 19 are inserted into the inner walls of the two sockets 11, and the end of the pin 13 close to the slope 17 is inserted into the inner wall of the positioning hole 3, so that the positioning rod 19 can be stably positioned on the inner wall of the socket 11 through the end of the pin 13 close to the slope 17, and then the protective cover 18 can be stably installed on the top of the fixing base 8 to protect the tap changer 9. There is no need to tighten the threads in the traditional structure, which improves the convenience of installation.

[0032] See Figure 3 and Figure 4 A through hole is provided on the outside of the circular cover 12, and the through hole passes through the circular cover 12 and the fixing seat 8 and communicates with the plug hole 11. The pin 13 is slidably connected to the inner wall of the through hole, so that when the protective cover 18 needs to be removed from the top of the fixing seat 8, the pull plate 20 can be pulled to drive the pin 13 to slide on the inner wall of the through hole, thereby realizing the separation of the slope 17 from the inner wall of the positioning hole 3.

[0033] See Figure 2 and Figure 5 Two side frames 2 are symmetrically fixed on the outside of the base 1. The tops of the two side frames 2 are in contact with the bottom of the transformer body 7, so that the transformer body 7 can be supported and positioned, thereby ensuring the stability of the transformer body 7 after installation and ensuring that the bottoms on both sides will not be in a suspended state.

[0034] See Figure 3 The tap changer 9 is arranged in the inner cavity of the protective cover 18. The outer diameter of the tap changer 9 is adapted to the inner wall diameter of the protective cover 18. The top of the tap changer 9 is rotatably connected with a rotating piece, so that the protective cover 18 can be installed to the top of the fixing seat 8 with a tight fit, thereby ensuring the protection effect of the tap changer 9 and ensuring that it will not be exposed to the outside and will not easily come into contact with rainwater and foreign objects from the outside. The rotating piece increases the convenience during phase change and facilitates manual rotation.

[0035] Working principle: When using the device, first slide the slider 5 to adjust the fixing bar 6 to different positions, so as to facilitate the installation of the fixing bar 6 to different positions by matching the bolts and the mounting holes, thereby improving the convenience of the device during installation and being applicable to different installation environments. At the same time, the rotating piece can be rotated to correspond to the positions of the notches 10 at different positions, thereby realizing phase switching to convert electrical energy. Then, the protective cover 18 can be taken and the two positioning rods 19 at the bottom thereof can be inserted into the inner walls of the two sockets 11, and then the bottoms of the two positioning rods 19 can abut against the slope 17 until the end of the pin 13 close to the slope 17 is completely retracted to the through hole on the inner wall of the fixing seat 8. The positioning rod 19 can be fully inserted into the inner wall of the hole 11. At this time, the end of the pin 13 close to the slope 17 corresponds to the position of the positioning hole 3. The gasket 2 16 and the pin 13 can be pushed to move with the help of the force of the return spring 15 until the end of the pin 13 close to the slope 17 is inserted into the positioning hole 3, so that the protective cover 18 can be quickly installed to protect the tap changer 9. When the protective cover 18 needs to be removed, the pull plate 20 is pulled to drive the pin 13 to slide on the inner wall of the through hole, thereby realizing the slope 17 to be separated from the inner wall of the positioning hole 3, and the positioning rod 19 can be removed from the inner wall of the hole 11 for disassembly.
