Description

Disconnector Operation Training Platform Technical Field

[0001] This application relates to the technical field of power training equipment, and in particular to a disconnector operation training platform. Background Technology

[0002] Electricity is a vital energy source for people's lives and business production, thus placing high demands on the performance of electrical equipment and the maintenance skills of electrical maintenance personnel when equipment malfunctions. For new employees just entering the power industry, frequent training on basic maintenance operations using practical training platforms is essential for quickly and effectively improving their hands-on skills.

[0003] Taking a knife switch operation training platform as an example, a traditional knife switch operation training platform mainly includes a support, a horizontal drive rod, a moving contact, and a stationary contact. The stationary contact is installed in a preset position on the support, and the horizontal drive rod is set on the support and connected to the moving contact. When the trainee presses the knife switch, the horizontal drive rod first drives the moving contact to rotate 90° in the horizontal plane so that the moving contact extends into the contact cavity of the stationary contact. Then, with the help of a motor preset in the horizontal drive rod, the moving contact is driven to rotate 90° in the vertical plane so that the moving contact can make contact with the stationary contact and conduct electricity. The operation steps of the moving contact are complex, the movement stroke is long, and the time is long, which greatly reduces the efficiency and experience of practical training. Summary of the Invention

[0004] Therefore, it is necessary to provide a knife switch operation training platform to address the problems of complex operation steps and low motion efficiency of moving contacts, which affect the efficiency and experience of practical training.

The stationary contact has a receiving cavity for receiving the moving contact after the extension action, so that the moving contact and the stationary contact can make contact and conduction.

[0010] This solution's disconnector operation training platform is used for training power workers in maintenance operations. In the initial state, the moving contact and the stationary contact are in a horizontal relative relationship. After controlling the host, the host outputs a working command to the telescopic drive component, which then drives the moving contact to extend, allowing it to move in a straight line and enter the receiving cavity to make contact with the stationary contact and conduct electricity.

Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0029] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0030] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly.

[0032] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0033] Referring to Figures 1 and 2, a knife switch operation training platform 100 according to an embodiment of this application is shown, including a support base 10, an operating host 20, a moving contact 30, and a stationary contact 40.

[0034] The operating host 20 is mounted on the support base 10. The operating host 20 includes a chassis, which contains functional components such as an operation panel and a wiring panel, facilitating training for power workers in operating mode control and wiring.

[0035] In addition, the host computer 20 also includes a carrier rod 21 and a telescopic drive assembly. The carrier rod 21 is horizontally positioned above the chassis, for example, the carrier rod 21 is assembled to the chassis via a vertical shaft. At least one end of the carrier rod 21 extends out of the side of the chassis in the axial direction (i.e., the length direction), that is, the end of the carrier rod 21 extending out of the side of the chassis does not coincide with the projection of the chassis in the vertical direction.

[0036] The telescopic drive assembly is mounted on the carrier rod 21, specifically at the end of the carrier rod 21 that extends out of the side of the chassis; the moving contact 30 is connected to the telescopic drive assembly, and the moving contact 30 can move along the axial direction of the carrier rod 21 under the drive of the telescopic drive assembly; the stationary contact 40 is mounted on the support base 10 and is horizontally opposite to the moving contact 30, and the stationary contact 40 is provided with a receiving cavity, which is used to receive the moving contact 30 after the extension action so that the moving contact 30 and the stationary contact 40 can make contact and conduction.

[0037] In summary, implementing the technical solution of this embodiment will have the following beneficial effects: The disconnector operation training platform 100 of this solution is used in situations where power workers are trained in maintenance operations. In the initial state, the moving contact 30 and the stationary contact 40 maintain a horizontal relative relationship. When the control host 20 is activated, the control host 20 outputs a working command to the telescopic drive assembly, which then drives the moving contact 30 to extend, allowing the moving contact 30 to move in a straight line and extend into the receiving cavity to make contact with the stationary contact 40 and conduct electricity. Compared with traditional technology, the movement steps of the moving contact 30 in this solution are simple and the movement efficiency is high, which helps to improve the practical training efficiency and experience of power workers.

[0038] Based on the above embodiment, the end of the carrier rod 21 facing the stationary contact 40 is recessed inward to form a mounting hole. The telescopic drive assembly is embedded in the mounting hole. One of the outer wall of the telescopic drive assembly and the hole wall of the mounting hole has a protrusion, and the other of the outer wall of the telescopic drive assembly and the hole wall of the mounting hole has a groove. The protrusion is engaged in the groove. By means of the protrusion being engaged in the groove, a clamping force can be generated on the telescopic drive assembly to ensure that the telescopic drive assembly is firmly installed in the mounting hole and will not loosen or fall off.

[0039] Specifically, in one embodiment, the telescopic drive assembly includes a motor, a cam, a pivot pin, and a push-pull rod. The motor is fixedly connected to the center of the cam wheel, the circumferential protrusion of the cam wheel is rotatably connected to the pivot pin, one end of the push-pull rod is rotatably connected to the pivot pin, and the other end of the push-pull rod is connected to the moving contact 30. During operation, when the motor drives the cam to rotate clockwise, the cam drives the push-pull rod to pull the moving contact 30 back into the mounting hole. When the motor drives the cam to rotate counterclockwise, the cam drives the push-pull rod to push the moving contact 30 out of the mounting hole and into the receiving cavity. This design features a simple structure for the telescopic drive assembly, stable power output, and flexible control over the telescopic movement of the moving contact 30.

[0040] Of course, in other optional embodiments, the telescopic drive component can also be a telescopic power device such as a cylinder, electric actuator, a combination of motor and rack and pinion module, or a combination of cylinder and scissor mechanism, depending on actual needs.

[0041] In practical applications, installation dimensional errors, component wear after prolonged operation leading to reduced alignment accuracy, or tools left around the moving contact 30 and / or stationary contact 40 may cause interference, preventing the moving contact 30 from smoothly extending into the receiving cavity. To address this, based on any of the above embodiments, the push-pull rod includes a first rod segment, a pressure sensor, and a second rod segment. The first rod segment is connected to the second rod segment via the pressure sensor. The end of the first rod segment furthest from the pressure sensor is rotatably connected to a pivot pin, and the end of the second rod segment furthest from the pressure sensor is connected to the moving contact 30. During operation, the pressure sensor can detect the pressure on the push-pull rod in real time. When an abnormal pressure is detected, the pressure sensor will send a signal to the controller or alarm to alert personnel to intervene promptly and eliminate the fault and potential hazard.

[0042] Furthermore, in another embodiment, the receiving cavity has an inlet and outlet facing the moving contact 30, and the sidewalls of the inlet and outlet are provided with flared portions. The flared portions are used to make it easier for the moving contact 30 to extend into the receiving cavity. For example, the flared portion can be any one of annular chamfer, annular fillet, annular conical surface, etc., as long as the end with the larger diameter of the flared portion is positioned directly opposite the moving contact 30. In this way, even if there is a misalignment between the moving contact 30 and the stationary contact 40, the moving contact 30 can be effectively inserted into the receiving cavity.

[0043] To ensure that the moving contact 30 extends more accurately into the preset position within the receiving cavity, in one embodiment, the knife switch operation training platform 100 further includes a position sensor. The position sensor is disposed on the side wall of the receiving cavity and is used to detect whether the moving contact 30 extends into the preset position within the receiving cavity. The position sensor is electrically connected to the telescopic drive assembly.

[0044] For example, the position sensor can be any of the following, but not limited to, infrared sensors, laser sensors, proximity switches, etc.

[0045] Furthermore, in any of the above embodiments, the switch operation training platform 100 also includes a flip-drive assembly, which is disposed on the support base 10. The stationary contact 40 includes a stationary contact plate, which is drivenly connected to the flip-drive assembly. When the moving contact 30 extends into the receiving cavity, the flip-drive assembly drives the stationary contact plate to rotate to abut against the moving contact 30. When the moving contact 30 slides into the receiving cavity frequently for a long time and makes sliding contact with the stationary contact 40, the moving contact 30 is prone to wear with the stationary contact 40. Due to the increased wear, a gap will appear between the moving contact 30 and the stationary contact 40, resulting in poor contact. Replacing the moving contact 30 or the stationary contact 40 will lead to increased costs and reduced utilization. To address this, this solution sets up a flip drive assembly connected to the stationary contact plate. When the moving contact 30 extends into the receiving cavity, the flip drive assembly drives the stationary contact plate to actively flip toward the moving contact 30, so that the stationary contact plate can overcome the gap and actively contact and adhere to the moving contact 30, ensuring effective contact and conduction between the stationary contact 40 and the moving contact 30.

[0046] Specifically, in the above embodiments, the flip-drive assembly includes a flip driver and an elastic buffer. The flip driver is connected to the stationary contact plate via the elastic buffer. The flip driver outputs a flip driving force to drive the stationary contact plate to contact the moving contact 30. For example, the stationary contact plate is hinged and rotated on the support base 10. The flip driver outputs a linear thrust to push the stationary contact plate to flip and contact the moving contact 30. Furthermore, by adding an elastic buffer between the flip driver and the stationary contact plate, the elastic buffer elastically contracts and absorbs energy at the moment of contact between the stationary contact plate and the moving contact 30, preventing deformation damage or noise caused by rigid collision between the stationary contact plate and the moving contact 30.

[0047] Please refer to Figures 1 and 2. Furthermore, based on any of the above embodiments, the support base 10 includes a carrier plate 11, a first upright 12, and a second upright 13. The first upright 12 and the second upright 13 are respectively disposed at both ends of the carrier plate 11 along its length. A stationary contact 40 is provided at the upper end of both the first upright 12 and the second upright 13. Two moving contacts 30 are provided, each corresponding to one of the stationary contacts 40. Compared to one set of moving contacts 30 contacting the stationary contacts 40, simultaneously providing two sets of moving contacts 30 in contact with the stationary contacts 40 results in higher reliability and helps ensure electrical conductivity.

[0048] Furthermore, the knife switch operation training platform 100 also includes a protective cover 50, which is mounted on the first upright 12 and the second upright 13 and covers the outside of the stationary contact 40. The protective cover 50 is used to separate the operator from the stationary contact 40 to prevent the operator's clothing, tools, etc. from being caught in the stationary contact 40 and / or the moving contact 30 when it operates, thus preventing safety accidents.

[0049] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0050] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
