[0002] Three-phase longitudinal and transverse power transformation technology is an advanced power conversion technology, which is based on three-phase transformer, and realizes controllable online exchange and transmission of electric power between different phases through specific circuit design and control strategy. Three-phase longitudinal and transverse power transformation technology has been widely used in power system due to its flexibility and efficiency. However, in the actual construction process, the positioning, fixing and protection of the transformer and the wire have always been a problem for construction personnel.

[0003] The traditional three-phase longitudinal and transverse power transformation construction protection device usually uses a simple fixing frame and wire groove to support and fix the transformer and wire.

[0004] However, since the fixing frame is a rigid structure, it cannot be adjusted according to the actual size of the transformer, which may cause instability or looseness during the fixing process. In addition, the position of the wire is positioned by the wire groove, and when the wire is subjected to external force, the wire is easily worn by the wire groove, affecting the service life. SUMMARY

[0005] The utility model aims at at least solving one of the technical problems existing in prior art. To this end, the utility model provides a protection device for three-phase longitudinal and transverse power transformation construction, which can adjust and position transformers of different sizes by setting first and second positioning plates. When external force acts on the wire, the protection block and second spring can absorb and disperse the impact force, preventing the wire from being damaged.

[0006] To achieve the above-mentioned purpose, according to the first aspect of the utility model, a protection device for three-phase longitudinal and transverse power transformation construction is provided, which comprises a mounting plate, a positioning mechanism and a protection mechanism. The positioning mechanism comprises a first positioning plate, a second positioning plate and a guide rod. The first positioning plate is fixedly arranged on the mounting plate. The mounting plate side wall is provided with a guide groove. The guide rod is arranged in the guide groove. The second positioning plate is provided with a sliding block at the bottom. The sliding block is in sliding cooperation with the guide rod. The second positioning plate is arranged above the first positioning plate. A first spring is arranged between the top of the sliding block and the side wall of the guide groove. The first and second positioning plates are used for positioning the transformer. The protection mechanism comprises a protection block and a second spring. A plurality of wire grooves are formed in the first and second positioning plates. The wire grooves are used for placing wires. The wire groove side wall is provided with the protection block. The protection block is connected with the second spring inside the wire groove.

[0007] As a further embodiment of this utility model: a limiting plate is provided on one side of the first positioning plate and the second positioning plate, and a movable plate is provided on the other side. The limiting plate is fixedly set and limits one side of the transformer, and the movable plate is slidably set and limits the other side of the transformer.

[0009] As a further embodiment of this utility model, the protective block has a rounded corner on the side facing outward from the wire groove.

[0010] As a further embodiment of this utility model: the size of the slider is adapted to the guide groove, and the second spring is sleeved on the guide rod.

[0011] As a further aspect of this utility model: the size of the moving block is adapted to the size of the moving slot.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. This utility model provides a stable support point for the transformer by setting a first positioning plate. Simultaneously, the second positioning plate, through the sliding cooperation of a slider and a guide rod, can be adjusted within a certain range to accommodate transformers of different sizes. Furthermore, under the action of a first spring, the second positioning plate can tightly fit the transformer, ensuring accurate and stable positioning. By setting a wire groove, space is provided for wire installation, while the protective block, through the second spring, forms an elastic protective barrier. When external forces act on the wire, the protective block and the second spring can absorb and disperse the impact force, preventing damage to the wire. The protective block also prevents the wire from wearing down due to vibration or friction, extending the wire's service life.

[0014] 2. This utility model drives the lead screw to rotate by rotating the knob, thereby adjusting the position of the moving plate. With the cooperation of the limiting plate, it can achieve all-round limiting and fixing of the transformer, ensuring the stability and accuracy of the transformer during installation. This helps to improve the operating efficiency and safety of the power system, and can adapt to transformers of different sizes, thus improving the applicability and flexibility of the protection device.

[0015] 3. By setting rounded corners, this utility model can effectively reduce the friction between the wire and the protective block when installing and positioning the wire, making it easier to install the wire into the wire groove, while reducing the wear of the wire and improving its service life.
