Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a power frequency resonant transformer. Background Technology

[0002] A power frequency resonant transformer is a special type of transformer that combines power frequency power supply and the principle of resonance. It is mainly used in high voltage testing, power equipment inspection, capacitor compensation and other fields. Its core feature is that it generates high voltage or large current at power frequency (50Hz or 60Hz) through a resonant circuit, while optimizing the size and efficiency of the equipment.

[0003] Power frequency resonant transformers are used in power systems for voltage transformation and power transmission. They operate based on the principle of electromagnetic induction. Existing equipment may encounter emergencies such as short circuits or overloads during operation, requiring rapid power disconnection to prevent accidents. However, these transformers usually lack efficient emergency disconnection mechanisms, and the power disconnection process is slow or unreliable, which can easily cause safety hazards and increase the risk of fire or equipment damage. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as the lack of efficient emergency disconnection mechanisms, slow or unreliable power-off processes, which can easily lead to safety hazards and increase the risk of fire or equipment damage. Therefore, this invention proposes a power frequency resonant transformer.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A power frequency resonant transformer includes a transformer body, a base plate fixedly connected to the bottom of the transformer body, the four corners of the base plate being rounded, handles for moving the transformer body fixedly connected to both sides of the transformer body, both handles being provided with rubber anti-slip sleeves, a line connection terminal provided on the top of the transformer body, heat dissipation holes and a filter screen provided on the rear side of the transformer body, and a cutting mechanism for reducing safety hazards fixedly connected to the front side of the transformer body.

[0007] In one possible design, the cutting mechanism includes two connecting rods, an inner plate, a hydraulic cylinder, a connecting block, a cutter, a front hole, and a front box. One end of each of the two connecting rods is fixedly connected to both sides of the same transformer body by bolts. The two sides of the inner plate are fixedly connected to the sides of the two connecting rods that are close to each other. The hydraulic cylinder is fixedly mounted on the inner plate by bolts and connected to a hydraulic pump and an oil tank. The output end of the hydraulic cylinder is fixedly connected to the front side of the connecting block. The rear side of the connecting block is fixedly connected to the cutter. The front box is fixedly mounted on the front side of the transformer body. The front box has multiple wiring holes for easy passage of wires. The front hole is located on the front side of the front box and fits with the cutter.

[0008] In one possible design, a groove is provided on the rear inner wall of the front box to fit the cutter, and an alloy plate is provided on the inner wall of the groove to facilitate cutting the circuit. The two alloy plates are made of copper-tungsten alloy.

[0009] In one possible design, the front sides of the connecting block are fixedly connected with positioning rods to facilitate the movement of the cutter. One end of each of the two positioning rods slides through the rear sides of the same inner plate and is fixedly connected with a limiting plate.

[0010] In one possible design, a top cover for protecting the line connection end is fixedly connected to the top of the transformer body. The front side of the top cover is set as an open part, and a cover plate for closing is slidably arranged on the top cover. The front and rear sides of the cover plate are provided with gripping grooves for easy handling, and the inner walls of the two gripping grooves are provided with anti-slip textures.

[0011] In one possible design, locking casters are fixedly connected to the four bottom corners of the base plate.

[0012] In this application, the transformer body realizes voltage transformation and power transmission conversion based on the law of electromagnetic induction. The transformer body is equipped with a primary coil and a secondary coil. By using the different turns ratio of the two, based on the principle of electromagnetic induction, an alternating magnetic field of a specific frequency is generated under power frequency conditions in conjunction with a resonant circuit, so as to complete the efficient transmission and conversion of power from the primary to the secondary.

[0013] In terms of safety protection, the hydraulic cylinder and its related components constitute an emergency cut-off system. The hydraulic cylinder uses standard hydraulic components, and its hydraulic circuit is connected to an independently set hydraulic pump and oil tank system. It is also connected to an external controller via a line and powered by an external power source. When an emergency power cut-off is required, the external controller issues a command to start the hydraulic system. The hydraulic pump pressurizes hydraulic oil into the hydraulic cylinder, driving the piston of the hydraulic cylinder to extend and push the connecting block forward. A cutter is welded to the front side of the connecting block, and two positioning rods are also welded to the front side of the connecting block. The positioning rods are made of Cr material and slide through the rear end of the inner plate to connect to the limiting plate, ensuring the precise movement trajectory of the cutter. The cutter moves forward with the connecting block, passes through the front hole on the front side of the front box, and cooperates with the copper-tungsten alloy plate embedded in the groove. The alloy plate forms a V-shaped shearing edge, which cuts the cable passing through the wire hole in a short time, realizing the emergency power cut-off function.

[0014] The beneficial effects of this utility model are as follows:

[0015] In this utility model, the cutting mechanism installed on the front side of the transformer body is a key component for safety protection. The cutter is made of alloy steel forging, with high blade hardness, ensuring cutting strength and durability. The front box has multiple wiring holes for cables to pass through, and a front hole matching the cutter is set on the front side. The rear inner wall has a groove and an alloy plate is embedded to form a V-shaped shearing edge, ensuring the cutting effect. In case of emergency, the cable can be cut in a short time, effectively reducing safety hazards and improving the safety of equipment use. Attached Figure Description

[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] In one embodiment: Refer to Figures 1-4 A power frequency resonant transformer includes a transformer body 1. The transformer body 1 uses the law of electromagnetic induction to achieve voltage transformation through the turns ratio of the primary coil and the secondary coil. In conjunction with the resonant circuit, it generates an alternating magnetic field of a specific frequency under power frequency conditions to complete the efficient transmission and conversion of electrical energy. A base plate 2 is welded to the bottom of the transformer body 1. The four edges of the base plate 2 are chamfered to form an arc structure to avoid scratching the operator during handling. Locking casters 3 are installed at the four corners of the bottom of the base plate 2. The casters are made of high-strength nylon material, and each caster is equipped with an independent braking device, which facilitates the movement of the equipment and fixes its position. Handles 4 are symmetrically welded on both sides of the transformer body 1. The surface of the handles 4 is covered with a 3mm thick rubber anti-slip sleeve. The surface of the anti-slip sleeve is pressed with a diamond pattern to enhance the friction when gripping.

[0023] The top wiring connection area is equipped with a top cover 5, which is made of 1.5mm thick cold-rolled steel plate and bent into shape. An open area is left on the front side for easy wiring operation. A cover plate 6 is slidably installed on the top cover 5. The cover plate 6 has gripping grooves 8 on both sides, and the grooves are pressed with horizontal anti-slip textures to facilitate push and pull operation by the user. The cover plate 6 is slidably engaged with the top cover 5 by two stainless steel guide rails. The spacing between the guide rails matches the width of the cover plate 6 to ensure smooth sliding without jamming. The rear heat dissipation area uses a punching process to form regularly arranged heat dissipation holes with a hole diameter of 5mm and a hole spacing of 10mm. The outside of the heat dissipation holes is covered with a removable filter screen. The filter screen is made of 304 stainless steel with a mesh count of 80 mesh and is fixed to the transformer body 1 by four spring clips for easy periodic disassembly and cleaning.

[0024] The front-mounted cutting mechanism is a key component for safety protection. Two connecting rods 7 are fixed to both sides of the transformer body 1 with bolts. The inner plate 9 is welded between the connecting rods 7 to form a support frame. The hydraulic cylinder 10 uses a standard hydraulic component and is fixed to the center of the inner plate 9 with bolts. Its hydraulic circuit is connected to an independently set hydraulic pump and oil tank system. The output end of the hydraulic cylinder is connected to the connecting block 15. The cutting blade 16 is welded to the rear side of the connecting block 15. The cutting blade 16 is forged from Cr12MoV alloy steel with a cutting edge hardness of HRC58-62. The front box 13 is fixed to the front side of the transformer body by welding. The box has multiple wiring holes 14 for cable routing. The front side of the front box 13 has a front hole 17 that matches the cutting blade 16. The rear inner wall has a groove 18. The groove 18 is embedded with a copper-tungsten alloy plate 19. The two alloy plates 19 form a V-shaped shearing edge to ensure the cutting effect.

[0025] This application can be used in the field of electrical engineering, or in other fields applicable to this application.

[0026] In another embodiment: Reference Figures 1-4 A power frequency resonant transformer, comprising:

[0027] Two positioning rods 11 are welded to the front of the connecting block 15. The positioning rods 11 are made of 40Cr material and slide through the rear end of the inner plate 9 to connect to the limiting plate 12, ensuring the precise movement trajectory of the cutter 16 and avoiding deviation that affects the cutting effect. When an emergency power cut is required, the hydraulic system can be activated by an external controller to drive the hydraulic cylinder 10 to extend, push the connecting block 15 to drive the cutter 16 forward. The cutter 16 passes through the front hole 17 and cooperates with the alloy plate 19 in the groove 18, completing the cutting of the cable passing through the line hole 14 within 0.5 seconds, effectively reducing safety hazards.

[0028] However, as is well known to those skilled in the art, the working principle and wiring method of the transformer body 1 and the hydraulic cylinder 10 are commonplace and are all conventional means or common knowledge. They will not be described in detail here. Those skilled in the art can make any selections according to their needs or convenience. The hydraulic cylinder 10 is connected to an external controller through a circuit and is powered by an external power source.
