Description

Technical Field

[0001] The present invention relates to the technical field of voltage transformers, and in particular to an electromagnetic voltage transformer protection device and method. Background Art

[0002] An electromagnetic voltage transformer is a voltage measuring device that converts a primary voltage into a secondary voltage in proportion through electromagnetic induction. It is based on Faraday's law of electromagnetic induction and the principle of transformer. It usually consists of a main winding (primary winding) and one or more secondary windings (secondary windings). The two are connected by an iron core. The primary winding is connected to a high-voltage circuit. When a high voltage passes through, a magnetic field is generated, which is transmitted to the secondary winding through the iron core. According to the law of electromagnetic induction, the change in the magnetic field generates an induced electromotive force in the secondary winding. Since the secondary winding has fewer turns, the high-voltage signal is converted into a lower voltage signal output. The electromagnetic voltage transformer protection device is a device that protects the electromagnetic voltage transformer during transportation and can prevent the device from being squeezed and deformed by external forces.

[0003] Existing electromagnetic voltage transformer protection devices are widely used and can provide certain protection. However, if the electromagnetic voltage transformer passes through bumpy roads during transportation, the electromagnetic voltage transformer is likely to shake inside the protection device, which may cause damage to the electromagnetic voltage transformer. Therefore, an electromagnetic voltage transformer protection device is proposed to address the above problem. Summary of the Invention

[0004] In view of the above shortcomings, the present invention provides an electromagnetic voltage transformer protection device to solve the problem that the existing technology of transporting voltage transformers is prone to damage, as mentioned in the above background technology. The specific technical solution is as follows:

[0005] An electromagnetic voltage transformer protection device comprises a protective shell, wherein a top plate and a bottom plate are symmetrically arranged at the upper and lower ends of the protective shell;

[0006] The top plate and the bottom plate are fixedly connected at the edge of one side close to each other, and a plurality of fixing plates are fixedly connected, and a threaded groove is provided inside the fixing plate, and a plurality of mounting holes are provided inside the protective shell, and mounting bolts threadedly connected to the inner side of the threaded groove are inserted inside the mounting holes. A plurality of anti-collision strips are installed on the outside of the protective shell, and a tightener is installed inside the top plate. A plurality of positioning columns are fixedly connected to the top of the bottom plate, and a voltage transformer body placed on the top of the bottom plate is provided on the outside of the positioning columns. Protective foam is symmetrically provided on the outside of the voltage transformer body, and a receiving groove is provided on the side where the two protective foams are close to each other, and a through hole opened on one side of the protective foam is provided above the receiving groove.

[0007] Preferably, the positioning column is inserted into the inner side of the base of the voltage transformer body, and the voltage transformer body is arranged inside the receiving slot and fits tightly with the receiving slot.

[0008] Preferably, the anti-collision strip comprises a rubber strip fixedly connected to the outside of the protective shell, and a plurality of evenly distributed buffer grooves are provided inside the rubber strip.

[0009] Preferably, the compressor includes a threaded barrel fixedly connected to the inside of the top plate and passing through the top plate, the inner side of the threaded barrel is threadedly connected to a clamping bolt, the bottom end of the clamping bolt is fixedly connected to a vertically arranged extension rod, and the bottom end of the extension rod is fixedly connected to a rubber head.

[0010] Preferably, the extension rod and the rubber head are inserted into the inner side of the through hole, and the bottom end of the rubber head is tightly fitted with the top end of the voltage transformer body.

[0011] Preferably, a symmetrically arranged rubber plate is fixedly connected to the bottom edge of the bottom plate, and a limiting groove is symmetrically opened at the bottom end of the rubber plate. A protective tube fixedly connected to the center of the bottom end of the bottom plate is provided between the two rubber plates, and a plurality of symmetrically arranged limiting columns are fixedly connected to the top edge of the top plate.

[0012] Preferably, the limiting groove and the limiting column have the same shape and size, and the inner diameter of the protective tube is larger than the outer diameter of the threaded tube.

[0013] A method for protecting an electromagnetic voltage transformer comprises the following steps:

[0014] S1. When the voltage transformer body needs to be transported, first place the voltage transformer body on the top of the bottom plate and insert the positioning column into the base on the voltage transformer body. Then install the protective foam and place the two protective foams on both sides of the voltage transformer body until the voltage transformer body is located inside the storage slot and fits tightly with the storage slot. Next, put the protective shell on the outside of the two protective foams and place the top plate on the top of the protective shell. At this time, the fixing plate is located inside the protective shell, and the threaded groove is horizontally aligned with the mounting hole. Then insert the mounting bolt into the mounting hole and screw it into the inner side of the threaded groove to complete the assembly of the protective shell.

[0015] S2. Next, turn the compression bolt inside the threaded barrel to pass the extension rod and the rubber head through the perforation until the rubber head is close to the voltage transformer body and fits tightly against the voltage transformer body. This completes the protection of the voltage transformer body.

[0016] S3. When multiple sets of voltage transformer bodies need to be transported, one protective shell can be placed on top of another protective shell, with the limit column inserted into the inner side of the limit groove on the rubber plate, and the protective cylinder sleeved on the outer side of the compactor.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. In the present invention, the fixing plate, threaded groove, mounting hole, mounting bolt, clamp, positioning column, protective foam, storage groove and perforation are provided to protect the voltage transformer body and prevent the voltage transformer body from being squeezed and deformed. The clamp can limit the voltage transformer body so that it fits with the bottom plate and prevents the voltage transformer body from shaking inside the protective shell.

[0019] 2. In the present invention, the anti-collision strip, rubber strip and buffer groove can provide a certain degree of cushioning when the protective case is hit. When the protective case is hit, the rubber strip and buffer groove undergo elastic deformation and absorb part of the impact force, thereby reducing the impact force on the protective case.

[0020] 3. In the present invention, by providing the rubber plate, limiting groove, protective cylinder and limiting column, when multiple sets of voltage transformer bodies need to be transported, one protective shell can be placed on top of another protective shell, the limiting column is inserted into the inner side of the limiting groove on the rubber plate, and the protective cylinder is sleeved on the outer side of the compressor. This design can limit the stacked protective shells and prevent the upper protective shell from falling. BRIEF DESCRIPTION OF THE DRAWINGS
