Description

Technical Field

[0001] This utility model relates to the field of transformer test bench technology, specifically a telescopic column-mounted transformer test bench testing device. Background Technology

[0002] A transformer platform is a supporting structure used to install outdoor distribution transformers. It is usually made of materials such as poles, channel steel, or angle steel. It can fix the transformer and related equipment on the overhead line to realize the distribution and transmission of electrical energy. The transformer platform assessment device is a comprehensive device used to simulate the actual operating environment of the transformer platform and to conduct practical training and assessment of skills such as installation, commissioning, and maintenance.

[0003] Traditional utility pole test stands, whether made of iron or cement, are over 4 meters tall and very heavy, making them unsuitable for indoor installation. They cannot fit in elevators or stairwells, and are not suitable for teaching purposes in specific areas such as schools, shopping malls, or indoor training institutions. Furthermore, the transformers themselves are very heavy, difficult to move, and pose safety hazards when placed indoors. Therefore, a telescopic pole-mounted transformer test stand device has been proposed to effectively solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a retractable pole-mounted transformer test stand to solve the problems mentioned in the background art, such as the inability of current pole-mounted test stands to be installed indoors, the heavy weight of the transformer itself making it difficult to move, and the safety hazards of placing it indoors.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a telescopic pole-mounted transformer test platform, comprising a platform base and two telescopic frames installed above the platform base, with insulators installed above the two telescopic frames, a crossbeam installed above the two telescopic frames, a row of drop-out fuses installed above the crossbeams, a row of electromagnetic actuators installed above the row of drop-out fuses, a mounting frame installed above the two telescopic frames, a row of zinc oxide surge arresters installed above the mounting frame, and a wind direction indicator installed above the mounting frame.

[0006] Preferably, a control cabinet is installed above the platform base, and a transformer model is installed above the control cabinet. The transformer model is installed above the metal crossbeam, and the metal crossbeam is positioned below the two telescopic frames.

[0007] Preferably, the insulator is connected to a drop-out fuse via a high-voltage line, and the transformer model is connected to a control cabinet via a wiring harness.

[0008] Preferably, a positioning seat is installed above the mounting bracket, and a socket is installed through the interior of the positioning seat, and a wind direction indicator is rotatably installed inside the socket.

[0009] Preferably, the positioning seat is provided with a positioning component inside, wherein the positioning component includes two limiting blocks, and the two limiting blocks are slidably installed inside the positioning seat, and the inner ends of the two limiting blocks extend through into the interior of the socket.

[0010] Preferably, the outer surfaces of the two limiting blocks are inclined, and the two limiting blocks are symmetrically arranged about the vertical center line of the positioning seat.

[0011] Preferably, one end of a pull rope is fixedly connected to the outer side of the two limiting blocks, and the other end of the two pull ropes is fixedly connected to a lever via a guide wheel. The two levers are slidably mounted on the front side of the positioning seat via a return spring.

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

[0013] (1) The telescopic pole-mounted transformer test device divides the telescopic frame into two parts for easy transport into the elevator. The required height can be achieved by telescopic adjustment and bolt locking, which solves the problem that the pole cannot enter the building or classroom. The telescopic frame is fixed to the platform to ensure stability and safety, and the rest is built according to the standard configuration. Therefore, it solves the problem that the indoor structure cannot be restored and is more practical.

[0014] (2) When teaching indoors, in order to better fit the actual use scenario, the wind direction indicator device will simulate a wind direction status indication during each teaching or practice session. At this time, the operator needs to practice the operation sequence according to the wind direction. When the closing sequence is incorrect or the closing is not in place, the electromagnetic drive device will exit the switch and issue an alarm to remind the operator, thus improving the teaching quality.

[0015] (3) When the wind direction indicator needs to be positioned and installed, the telescopic column-mounted transformer test device only needs to insert the socket connected to the bottom of the wind direction indicator into the inside of the positioning seat. At this time, the two inclined limit blocks will shrink and move by the compression of the socket. Then, the two compression springs will automatically spring the two squeezed and shrunken limit blocks into the inside of the socket by their own elasticity. This can realize the positioning and fixing of the wind direction indicator after installation, and avoid the wind direction indicator from loosening and falling off during the wind direction test. The stability is better.

[0016] (4) When the wind direction indicator needs to be disassembled, stored and transported, the telescopic pole-mounted transformer test device only needs to press two levers to drive two pull ropes to retract and move. The two retracting pull ropes pull two limit blocks simultaneously through the guide wheel to retract and move. Then the socket can be taken out from the inside of the positioning seat to disassemble and store the wind direction indicator. The operation is more time-saving and labor-saving.

[0017] (5) The telescopic column-mounted transformer test device utilizes a reset spring installed on the front side of the positioning seat, and then connects levers to both ends of the reset spring. The two levers after being pressed and retracted can be elastically reset by the spring's own elastic force, which facilitates repeated disassembly and assembly in the later stage and makes it more practical.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model provides the following technical solution: a retractable pole-mounted transformer test stand device:

[0028] Example 1: To address the issues of existing utility pole supports being unable to be installed indoors, the heavy weight of transformers making them difficult to move, and the safety hazards of placing them indoors, the following solution is disclosed: a platform base 9, and two telescopic frames 2 installed above the platform base 9. Insulators 1 are installed above the two telescopic frames 2, and a crossbeam is installed above the two telescopic frames 2. A row of drop-out fuses 4 is installed above the crossbeam, and a row of electromagnetic actuators 3 is installed above the row of drop-out fuses 4. A mounting frame 10 is also installed above the two telescopic frames 2, and a mounting bracket 10 is installed above the mounting frame 10. A row of zinc oxide surge arresters 5 is installed, and a wind direction indicator 11 is also installed above the mounting frame 10. The high-voltage transmission line entering through insulator 1 passes through drop-out fuses 4 and zinc oxide surge arresters 5, leading the line to transformer model 6. Transformer model 6 converts the high voltage to low voltage, which is then transmitted to the user via the control cabinet 8 at the bottom. When power is interrupted or a fault occurs, power interruption or restoration operations are required. At this time, drop-out fuses 4 are used for opening and closing operations. Since wind affects the opening and closing of the circuit, different operating sequences are performed depending on whether there is wind or not. Incorrect operation can cause danger, such as... Figure 1 and Figure 2 As shown.

[0029] A control cabinet 8 is installed above the platform base 9, and a transformer model 6 is installed above the control cabinet 8. The transformer model 6 is installed above the metal crossbeam 7, and the metal crossbeam 7 is positioned below the two telescopic frames 2. The insulator 1 is connected to the drop-out fuse 4 through the high-voltage line, and the transformer model 6 is connected to the control cabinet 8 through the wiring harness.

[0030] The telescopic frame 2 is divided into two parts for easy transport into the elevator. The required height is achieved through telescopic adjustment, and bolts are used for tightening. This solves the problem of the pole not being able to enter the building or classroom. The telescopic frame 2 is securely fastened to the platform for stability and safety. The remaining parts are assembled according to standard configurations, thus resolving the issue of not being able to reassemble it indoors, resulting in better practicality. Figures 1-4 As shown.

[0031] During indoor teaching, to better reflect real-world scenarios, the wind direction indicator 11 simulates a wind direction during each lesson or practice session. Operators then need to practice the operating sequence according to the wind direction. If the closing sequence is incorrect or the closing is incomplete, the electromagnetic actuator 3 will disengage the switch and issue an alarm to alert the operator, thus improving teaching quality. Figure 1 and Figure 2 As shown.

[0032] In Embodiment Two, unlike Embodiment One, a disassembly and assembly component can be provided to assist in the quick disassembly and assembly of the wind direction indicator 11, thereby reducing the efficiency of the disassembly and assembly operations of the wind direction indicator 11 and making the operation more time-saving and labor-saving. The following is disclosed:

[0033] A positioning base 13 is mounted above the mounting bracket 10, and a socket 12 is installed through the interior of the positioning base 13. A wind direction indicator 11 is rotatably mounted inside the socket 12. A positioning assembly is provided inside the positioning base 13, comprising two limiting blocks 17. The two limiting blocks 17 are slidably mounted inside the positioning base 13, and their inner ends extend through into the interior of the socket 12. The outer surfaces of the two limiting blocks 17 are inclined, and the two limiting blocks 17 are symmetrically arranged about the vertical center line of the positioning base 13. This allows for adjustments when necessary. When installing the wind direction indicator 11, simply insert the socket 12 connected to the bottom of the wind direction indicator 11 into the positioning base 13. The two inclined limiting blocks 17 will then retract and move due to the pressure of the socket 12. Subsequently, the elastic force of the two compression springs 18 will automatically spring the retracted limiting blocks 17 into the socket 12, thus fixing the position of the installed wind direction indicator 11 and preventing it from loosening or falling off during wind direction testing. This improves stability. Figure 5 and Figure 6 As shown.

[0034] Two limit blocks 17 have one end of a pull rope 15 fixedly connected to their outer surfaces, and the other end of the two pull ropes 15 is fixedly connected to a lever 14 via a guide wheel. The two levers 14 are slidably mounted on the front side of the positioning seat 13 via a return spring 16. When the wind direction indicator 11 needs to be disassembled, stored, and transported, simply press the two levers 14 to retract the two pull ropes 15 via the return spring 16. This retracting pull rope 15 then pulls the two limit blocks 17 simultaneously via the guide wheel, allowing the socket 12 to be removed from the positioning seat 13 for disassembly and storage of the wind direction indicator 11. This operation is more time-saving and labor-saving. Figure 6 and Figure 7 As shown.

[0036] The contents not described in detail in this specification are existing technologies known to those skilled in the art.
