Abstract
Description
Technical Field
[0001] This utility model relates to the field of transformer technology, and in particular to transformers with multi-layer coatings. Background Technology
[0002] A transformer consists of an iron core (or magnetic core) and coils. The coils have two or more windings, of which the winding connected to the power supply is called the primary coil, and the remaining windings are called secondary coils.
[0003] According to the transformer disclosed in announcement number CN203941788U, it includes a housing, which includes a lower surface. A pressure relief valve rapidly moves to reduce the pressure inside the housing to a normal range, effectively protecting the housing. In the aforementioned document, the housing surrounds the internal components, but it is not coated with paint. This limits the overall wear resistance of the housing. Furthermore, the heat sinks on the outer wall of the housing can only conduct heat and cannot provide external protection for the transformer. Therefore, the transformer cannot protect its internal components during transportation or use. Utility Model Content

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0022] Reference Figures 1-3 A transformer with multi-layer coating includes a main body 1 and a notch opened on the main body 1, and the notch is coated with a wear-resistant layer. Two protective plates 2 corresponding to the notch are provided on the main body 1.
[0023] The main body 1 is equipped with a moving component 3 that allows the traction protection plate 2 to move.
[0024] The movable component 3 includes a movable cavity opened in the main body 1, and a symmetrically arranged bracket 31 is slidably sleeved in the movable cavity. A positioning block 32 extending into the main body 1 is sleeved in the bracket 31, and a spring 33 is welded between the positioning block 32 and the bracket 31. A protective plate 2 is disposed on the bracket 31. The bracket 31 guides the positioning block 32, thereby limiting the moving direction of the positioning block 32.
[0025] The movable cavity is provided with a sliding groove 34 for guiding the bracket 31. The bracket 31 is a U-shaped structure with one side opening. The spring 33 is horizontally welded to the side of the positioning block 32 extending into the bracket 31. The sliding groove 34 guides the bracket 31, so that the bracket 31 can smoothly pull the positioning block 32 when moving. The spring 33 resets the positioning block 32. When the positioning block 32 is in an unloaded state, the spring 33 can drive the positioning block 32 back to the initial position.
[0026] The main body 1 has two positioning grooves 35 that cooperate with the positioning block 32. When the positioning groove 35 corresponds to the positioning block 32, the positioning block 32 can be extended into the positioning groove 35 under the action of the spring 33. After the positioning block 32 is clamped by the positioning groove 35, the position of the protective plate 2 can be initially locked.
[0027] The main body 1 is equipped with a reinforcement mechanism 7 to reinforce the positioning block 32.
[0028] The reinforcement mechanism 7 includes two limiting rods 72 that are slidably sleeved on the main body 1, and a limiting block 73 extending into the positioning block 32 is integrally connected to the limiting rod 72. A second spring 75 is welded between the limiting rod 72 and the main body 1. The second spring 75 resets the limiting rod 72. When the limiting block 73 is disconnected from the positioning block 32, the second spring 75 can drive the limiting rod 72 and the limiting block 73 back to their initial positions.
[0029] Two traction rods 76 connected to the limiting rod 72 are slidably sleeved on the main body 1, and connecting plates 77 extending to the main body 1 are fixedly installed on the traction rods 76. (According to the attached instruction manual...) Figure 2 As shown, a threaded rod is fixedly installed on the bracket 31 and the connecting plate 77. To further explain, when it is necessary to install the protective plate 2, the screw cap can be installed on the screw rod, and the screw rod and the screw cap can be connected.
[0030] The main body 1 has a limiting groove 71 for guiding the limiting rod 72. The limiting groove 71 guides the limiting rod 72, so that the limiting rod 72 can smoothly pull the limiting block 73 when moving. The two ends of the spring 75 are connected to the limiting groove 71 and the limiting rod 72 respectively. The positioning block 32 has a limiting arc groove 74 for clamping the limiting block 73. When the positioning block 32 extends into the positioning groove 35, it extends into the positioning block 32 through the limiting block 73, thereby locking the position of the protective plate 2. The traction rod 76 has an F-shaped structure, and the connecting plate 77 is threaded with a fixing bolt connected to the main body 1.
[0031] A second protective plate 4 is placed between the two protective plates 2 to protect the notch, and the two protective plates 4 are integrally connected with evenly distributed intercepting rods 5 to protect the transformer.
[0032] According to the instruction manual Figure 1 As shown, the first protective plate 2 and the second protective plate 4 are trapezoidal structures. The first protective plate 2 is horizontally positioned on both sides of the recess, and the second protective plate 4 is vertically positioned on both sides of the first protective plate 2. The intercepting rod 5 is horizontally positioned. The second protective plate 4 is integrally connected with symmetrically arranged connecting ears 6 that extend into the first protective plate 2. The connecting ears 6 are threaded with reinforcing bolts that connect to the first protective plate 2. After the first protective plate 2 is moved out of the moving cavity, the second protective plate 4 is installed on the first protective plate 2, so that the first protective plate 2, the second protective plate 4, and the intercepting rod 5 can protect the main body 1 from the outside.
[0033] The wear-resistant layer includes fluorosilane-modified alumina coating, organosilicon-modified coating, epoxy resin-based composite coating, polyimide coating, and fluorocarbon coating. The fluorosilane-modified alumina coating is a composite coating formed by surface chemical modification of alumina (Al2O3) coating with fluorosilane. It combines the high hardness, wear resistance, and insulation of inorganic alumina with the low surface energy, hydrophobicity, and corrosion resistance imparted by fluorosilane.
[0034] Organosilicon-modified coatings are organic-inorganic hybrid coatings formed by introducing organosilicon groups (such as siloxane segments) into the molecular structure of traditional organic coatings (such as epoxy resins, polyurethanes, acrylates, etc.).
[0035] Epoxy resin-based composite coatings are a type of multifunctional coating formed by physical mixing or chemical compounding of epoxy resin as the matrix and adding second-phase materials such as inorganic fillers, organic polymers, fibers or functional additives.
[0036] Polyimide coatings have extremely high thermal stability, with long-term operating temperatures reaching 200-300℃ and short-term tolerance temperatures exceeding 500℃, maintaining structural stability even in high-temperature environments.
[0037] Fluorocarbon coatings are a type of high-performance coating that uses fluoropolymers as the main film-forming material. Their molecular structure contains strongly polar carbon-fluorine (CF) bonds, which endow the coating with excellent weather resistance, chemical stability and low surface energy.
[0038] The wear-resistant layer can protect the exterior of the main body 1, protecting and intercepting the friction-prone areas of the main body 1, thereby protecting the exterior of the main body 1.
[0039] The functional principle of this utility model can be explained through the following operation methods:
[0040] Prepare the raw materials required for the wear-resistant layer, and use a roller brush to sequentially coat the fluorosilane-modified alumina coating, organosilicon-modified coating, epoxy resin-based composite coating, polyimide coating, and fluorocarbon coating into the recess.
[0041] The screw cap is pulled onto the screw rod and rotated to connect the screw cap with the screw rod on the positioning block 32;
[0042] Remove the fixing bolt and pull the connecting plate 77 to move the traction rod 76. When the traction rod 76 moves, it pulls the limiting rod 72, causing one of the limiting blocks 73 to disconnect from the positioning block 32. Press the positioning block 32 with the screw cap. When the bracket 31 moves in the slide groove 34, it causes the positioning block 32 to move and abut against the main body 1. The spring 33 is stressed, causing the positioning block 32 to extend into the bracket 31.
[0043] Press the screw cap continuously to make the bracket 31 drive the positioning block 32 to correspond with another positioning groove 35. After the positioning block 32 and the positioning groove 35 correspond with each other, the positioning block 32 extends into the positioning groove 35 under the action of spring 1 33. Release the traction on the connecting plate 77. Under the action of spring 2 75, one of the limiting blocks 73 extends into the limiting arc groove 74 in the positioning block 32. Use the fixing bolt to connect the connecting plate 77 and the main body 1, so that the bracket 31 drives the protective plate 1 2 to extend to both ends of the notch.
[0044] Press down on the second protective plate 4 to move the second protective plate 4 into the connecting ear 6. Use a reinforcing bolt to connect the connecting ear 6 to the first protective plate 2, so that the first protective plate 2, the second protective plate 4, and the intercepting rod 5 can protect the exterior of the main body 1.
[0045] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
