Description

Technical Field

[0001] This application relates to the field of power system training equipment technology, and in particular to an adjustable high-voltage drop protection simulation training frame. Background Technology

[0002] High-voltage drop-out fuses (drop-out circuit breakers) are crucial protective devices in power systems. Their installation, maintenance, and replacement require skilled operators. Currently, traditional training equipment suffers from the following problems: fixed structure, unable to simulate operation on high-voltage lines at different heights; lack of realistic fault simulation capabilities; and insufficient safety, posing a risk of electric shock or mechanical injury during operation. Therefore, this paper presents an adjustable high-voltage drop-out fuse simulation training frame to address these issues. Utility Model Content

[0003] This application provides an adjustable high-voltage drop-out fuse simulation training frame. A lifting device (motor, take-up and release frame, lifting rope, rollers, and shafts) is installed on the support frame. First, during teaching, the motor can be controlled to rotate the take-up and release frame, and the lifting rope can be used to change the position of the lifting platform on the support frame, achieving realistic simulation and teaching of high-voltage line operation with high-voltage drop-out fuses at different heights. Second, during teaching, the operating ring can be pulled by the operating lever to achieve the closing and opening of the fuse tube and high-strength insulator, realizing realistic fault simulation. Finally, an arc simulator is installed between the upper and lower terminals. During teaching, when the fuse tube is in the open state, the arc simulator automatically lights up under the control of the control console; when the fuse tube is in the closed state, the arc simulator automatically turns off under the control of the control console. During this process, the voice broadcast device on the control console broadcasts the status of the fuse tube accordingly. The operation process is unlikely to cause electric shock or mechanical injury and is sufficiently safe.

[0004] This application provides an adjustable high-voltage drop protection simulation training frame, including a support frame, a motor fixed to the top of the support frame, a take-up and release frame connected to the output end of the motor, a lifting rope wound on the take-up and release frame, the end of the lifting rope passing through two rollers and fixed to the top of the support frame by hooks, the two rollers being installed on the top of the lifting platform, two rollers being provided on one side of the lifting platform, the two rollers being slidably placed in two tracks on both sides of the support frame, three insulators being provided on the top of the lifting platform, each of the three insulators being connected to a high-strength insulator, each high-strength insulator having an upper wire at the top and a lower wire at the bottom, each upper wire having a connecting buckle, each lower wire having a fuse tube installed at the bottom of the lower wire via a rotating device, each fuse tube having an operating ring at the end, and an arc simulator being provided between each upper wire and lower wire;

[0005] The motor, lower wiring and arc simulator wiring are connected to the same control console, which includes a voice broadcast device.

[0006] Furthermore, the motor is specifically a servo motor.

[0007] Furthermore, the lifting platform can be raised and lowered vertically.

[0008] Furthermore, a fall arrestor is installed at the top of the support frame, and the output end of the fall arrestor is connected to the top of the lifting platform.

[0009] Furthermore, the fuse tube and the connecting buckle can be fastened together.

[0010] Furthermore, an immediate stop switch is provided on the control panel.

[0011] As can be seen from the above technical solution, this application provides an adjustable high-voltage drop safety simulation training frame, including a support frame, a frame body with a retractable frame and a lifting platform, etc. A motor is fixed at the top of the support frame, and a kinetic energy output structure outputs kinetic energy to drive the retractable frame to realize the retraction and release of the lifting rope, thereby realizing the raising and lowering of the lifting platform and providing kinetic energy support for the raising and lowering of the lifting platform. The motor output end is connected to the retractable frame, the frame body for retracting and releasing the lifting rope, and the lifting rope is wound on the retractable frame. The structure controls the raising and lowering of the lifting platform under the rotation of the retractable frame. The end of the lifting rope passes through two rollers and is fixed by a hook. Fixed at the top of the support frame, two rollers are mounted on the top of the lifting platform, serving an auxiliary function to facilitate the sliding of the lifting rope and effectively reducing friction between the lifting rope and the lifting platform. This provides strong support for the easy raising and lowering of the lifting rope using the retraction frame. Two rollers are located on one side of the lifting platform, serving an auxiliary function to facilitate the lifting platform's raising and lowering within the support frame. These two rollers slide within two tracks on either side of the support frame. During raising and lowering, the tracks on which the rollers move are controlled. Three insulators are installed at the top of the lifting platform for insulation, reducing the risk of electrical leakage and improving the safety of the equipment. The system features three insulators, each connected to a high-strength insulator for insulation, effectively preventing leakage and reducing the risk of electrical leakage. Each high-strength insulator has an upper terminal at the top for connection to the power supply and a lower terminal at the bottom for connection to the control panel. Each upper terminal has a locking clip that closes with the fuse tube. The lower terminals each have a fuse tube installed via a rotating mechanism, functioning similarly to a switch for connecting and disconnecting the circuit. This system is used in teaching and practice to realistically simulate circuit conditions. To facilitate troubleshooting and provide educational purposes, each fuse tube is equipped with an operating ring at its end. During the closure and opening of the fuse tube, staff can easily operate the fuse tube using an operating lever. An arc simulator is installed between each upper and lower connection to simulate the circuit. When the fuse tube is in the open state, the arc simulator automatically lights up under the control of the control panel. When the fuse tube is in the closed state, the arc simulator automatically turns off under the control of the control panel to alert students to the operating status of the equipment and prevent dangerous situations such as electric shock, thus ensuring the safety of the equipment.

[0012] The motor, lower wiring, and arc simulator wiring are connected to the same control console, which plays a control role. It adopts an advanced intelligent control system to control the operation of the motor and the corresponding voice system broadcasts. The control console includes a voice broadcast device, which broadcasts the status of the fuse tube to better facilitate teaching and remind students of the equipment's operating status, effectively preventing dangerous situations such as electric shock.

[0013] In summary, the beneficial effects of this application are as follows:

[0014] 1. During the teaching process, the motor can be controlled to drive the take-up and release frame to rotate. The lifting rope can be used to change the position of the lifting platform on the support frame, thus achieving a realistic simulation and teaching of high-voltage line operation with high-voltage drop protection at different heights.

[0015] 2. During the teaching process, the operating ring can be pulled by the operating lever to realize the closing and opening of the fuse tube and the high-strength insulator, thus realizing a realistic fault simulation.

[0016] 3. An arc simulator is installed between the upper and lower wiring terminals. During the teaching process, when the fuse tube is in the open state, the arc simulator will automatically light up under the control of the console. When the fuse tube is in the closed state, the arc simulator will automatically turn off under the control of the console. During this process, the console's voice broadcast device will broadcast the status of the fuse tube accordingly. The operation process is unlikely to cause electric shock or mechanical injury, and the safety is sufficient. Attached Figure Description
