Description

Technical Field

[0001] The present application relates to the field of transformer components, and in particular to an insulating shield of a transformer. Background Art

[0002] The transformer mainly uses the electromagnetic mutual induction effect to transfer electric energy or transmit signals from one circuit to another. The electric energy output from the power plant needs to be converted by the transformer before it can be used by ordinary households. In order to ensure the safety of electricity use, it is necessary to set an insulating shield outside the transformer. For example, patent number CN219202889U discloses an insulating shield that is convenient for transformer maintenance. An insulating shield that can play a protective function is set outside the transformer.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the insulating shield in the above-mentioned patent has the defect that it is difficult to open the shields on both sides of the transformer at the same time. In order to ensure the protective effect of the insulating shield, it is necessary to set shields on both sides of the transformer. Since the transformer needs regular maintenance, the shield must be detachable, which makes the shields on both sides of the transformer more independent. If you want to remove them, you need to perform two operations, which makes the work efficiency relatively low. Therefore, an insulating shield for a transformer is proposed to solve the above problem.

[0004] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Utility Model Content

[0005] In order to solve the problem in the comparative patent that the insulating shield located on both sides of the transformer is difficult to open at the same time, the present application provides an insulating shield for a transformer.

[0006] The insulating shield of a transformer provided in the present application adopts the following technical solution:

[0007] A transformer insulation shield comprises a transformer body, two I-shaped steels and two shield bodies, wherein the transformer body is mounted on the two I-shaped steels, a fixed block is mounted on the side wall of the I-shaped steel, two parallel slide grooves are provided on the side wall of the fixed block, a moving cavity is provided in the fixed block, the side wall of the moving cavity is rotatably connected to a central gear, the top wall and the bottom wall of the moving cavity are respectively slidably connected to transverse racks, both of the two transverse racks are meshed with the central gear, support rods are mounted on the side walls of the transverse racks, the two support rods extend out of the slide grooves respectively, and the ends of the two support rods away from the transverse racks are respectively fixedly connected to the two side walls of the shield body.

[0008] Preferably, a heat dissipation hole is provided on the side wall of the shield body, and the heat dissipation hole is located opposite to the heat dissipation position of the transformer body.

[0009] Preferably, a plurality of slots are formed on the top wall of the shield body, and a rubber gasket is installed in each of the slots, and the rubber gasket abuts against the terminal side wall at the top of the transformer body.

[0010] Preferably, a fixing rod is rotatably connected to the top of the shield body, an insertion rod is installed on the side wall of the fixing rod, and another top wall of the shield body is provided with an insertion hole, and the insertion rod is inserted into the insertion hole.

[0011] Preferably, the top walls of the two shield bodies are each provided with a fixing rod, and at the corresponding position of the fixing rod, the two shield bodies are also provided with a plug hole.

[0012] In summary, this application includes the following beneficial technical effects:

[0013] The two fixing rods can connect the two shield bodies together to ensure that the two shield bodies will not accidentally detach in the absence of external force. When you want to separate the shields, you only need to open the two fixing rods and slide one of the shield bodies sideways, so that the transverse rack can drive the central gear to rotate, and then the two transverse racks move in opposite directions, thereby achieving the effect of separating the two shield bodies and improving the efficiency of repairing the transformer body.

[0018] The following is combined with Figure 1-3 This application is described in further detail.

[0019] The present application embodiment discloses an insulating shield for a transformer. Figure 1, an insulating shield of a transformer, comprising a transformer body 1, two I-shaped steels 2 and two shield bodies 3, the transformer body 1 is mounted on the two I-shaped steels 2, a fixing block 4 is mounted on the side wall of the I-shaped steel 2, two parallel slide grooves 5 are opened on the side wall of the fixing block 4, a heat dissipation hole 9 is opened on the side wall of the shield body 3, and the position of the heat dissipation hole 9 is directly opposite to the heat dissipation position of the transformer body 1. When the transformer body 1 is working normally, a large amount of heat will be emitted. In order to protect the heat dissipation safety of the transformer body 1, it is necessary to set the heat dissipation hole 9 on the side wall of the shield body 3;

[0020] The top wall of the shield body 3 is provided with a plurality of slots 10, each of which is provided with a rubber gasket 11, which abuts against the terminal side wall at the top of the transformer body 1. The transformer body 1 is provided with a terminal at the top. In order to ensure that the shield body 3 can be covered outside the transformer body 1, it is necessary to make the shield body and the outer shape of the transformer body 1 consistent as much as possible, so the slots 10 are required;

[0021] Reference Figure 3 The top of the shield body 3 is rotatably connected with a fixing rod 12, and a plug rod 13 is installed on the side wall of the fixing rod 12. A plug hole 14 is opened on the top wall of the other shield body 3, and the plug rod 13 is inserted into the plug hole 14. The fixing rod 12 can connect the two shield bodies 3 together during daily use to prevent the shield body 3 from being accidentally opened;

[0022] The top walls of the two shield bodies 3 are each provided with a fixing rod 12, and at the corresponding position of the fixing rod 12, the two shield bodies 3 are also provided with a plug hole 14, and the two fixing rods 12 fix the positions of the shield bodies 3 in different directions, further ensuring the connection relationship between the two shield bodies 3;

[0023] Reference Figure 2 A motion cavity is opened in the fixed block 4, and the side wall of the motion cavity is rotatably connected to the central gear 6. The top wall and the bottom wall of the motion cavity are respectively slidably connected to the transverse racks 7. The two transverse racks 7 are meshed with the central gear 6. The side walls of the transverse racks 7 are provided with support rods 8. The two support rods 8 extend from the slide grooves 5 respectively. The ends of the two support rods 8 away from the transverse racks 7 are respectively fixedly connected to the side walls of the two shield bodies 3. The two transverse racks 7 are respectively located at the top and bottom of the central gear 6. Therefore, when the central gear 6 rotates, the two transverse racks 7 will move in opposite directions.

[0024] The implementation principle of the insulating shield of a transformer in the embodiment of the present application is as follows: when you want to separate the two shield bodies 3, you can first rotate the two fixed rods 12 to make the insertion rod 13 leave the insertion hole 14, and then you can move one of the shield bodies 3 laterally, and the support rod 8 on the side wall of the shield body 3 will drive the transverse rack 7 to move, thereby causing the central gear 6 meshing with it to rotate, thereby driving the other transverse rack 7 to move. Since the two transverse racks 7 are respectively located on both sides of the central gear 6, the two transverse racks 7 will drive the two shield bodies 3 to move in two opposite directions, thereby easily opening the two shield bodies 3, making it convenient for the staff to inspect the internal transformer body 1.
