Description

Technical Field

[0001] This utility model belongs to the technical field of teaching equipment for transformer substation line loss, and more specifically relates to a teaching device for simulating and troubleshooting abnormal transformer substation line loss. Background Technology

[0002] The transformer substation line loss anomaly simulation and troubleshooting training is a training method targeting abnormal line loss issues in power supply substations. The simulation component constructs virtual or physical scenarios to simulate abnormal line loss conditions, such as high loss or negative loss, helping trainees intuitively understand the anomalies. The troubleshooting component focuses on analyzing the causes of anomalies, covering various aspects such as inconsistent file information, incorrect substation-customer relationships, equipment failure, electricity theft, and excessive technical line loss. Trainees must master skills in system diagnosis, on-site troubleshooting, data collection and investigation, and electricity theft investigation. Through hands-on exercises, they improve their ability to identify and handle abnormal line loss, ensuring the efficient and stable operation of the power system.

[0003] In the prior art, such as Chinese Patent No. CN215117893U, a comprehensive training device for intelligent overall protection and line loss anomaly investigation is disclosed. It consists of an installation cabinet, an operating cabinet, and a lifting mechanism. The installation cabinet includes a rectangular cabinet with an operating table on the top. The upper surface of the operating table has rectangular storage holes. The four corners of the lower surface of the installation cabinet are threaded with casters. The operating cabinet is located inside the installation cabinet and includes a main cabinet. In use, the forward and reverse motor controls the X-shaped telescopic frame to raise the operating cabinet on the support plate. Then, the auxiliary cabinet is opened through the L-shaped groove. The first and second operating surfaces can be used together for training tests, expanding the installation position of electrical components and terminal interfaces. After the training, the operating cabinet can be returned to the installation cabinet, avoiding space waste and preventing the electrical components on the first and second operating surfaces from being exposed to dust for a long time, which may reduce their service life.

[0004] While the above-mentioned solution has the advantages mentioned above, its disadvantages are as follows: Although it can expand the installation space for electrical components and terminal interfaces by setting auxiliary cabinets on both sides of the front of the main cabinet, thereby increasing the training content, and placing two symmetrically set protruding strips on the back of the auxiliary cabinet can prevent the electrical components on the main cabinet and the auxiliary cabinet from touching each other, the auxiliary cabinet and the main cabinet are only connected by hinges. When the back of the auxiliary cabinet is hit, the auxiliary cabinet will rotate towards the front of the main cabinet under the action of the hinges, causing the auxiliary cabinet to collide with the main cabinet. This may damage the shell of the auxiliary cabinet and the main cabinet, and may affect the electrical components on the auxiliary cabinet and the main cabinet, thereby affecting the trainees' simulation and troubleshooting of abnormal line loss in the transformer area. Utility Model Content

[0005] In view of this, the present invention provides a teaching device for simulating and troubleshooting abnormal line loss in a transformer substation. The purpose is to solve the problem in the prior art where insufficient structural strength between the auxiliary cabinet and the main cabinet leads to damage to the shells of the auxiliary cabinet and the main cabinet, which affects the electrical components on the auxiliary cabinet and the main cabinet, thereby affecting the trainees' ability to simulate and troubleshoot abnormal line loss in a transformer substation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A teaching device for simulating and troubleshooting abnormal line losses in a transformer substation includes an installation cabinet with a hollow interior. The installation cabinet contains a main cabinet and two auxiliary cabinets, which are mounted on a movable plate fixed to the bottom of the main cabinet. The auxiliary cabinets are movably connected to the main cabinet via a limiting mechanism. The top of the installation cabinet has a through-slot for the main cabinet and auxiliary cabinets to pass through. The upper end of the movable plate extends through the through-slot, and the lower end slides within the installation cabinet. A lifting mechanism is connected to the lower part of the movable plate for raising and lowering the main cabinet and auxiliary cabinets. A dustproof plate is also provided on the top of the main cabinet, with one bottom side fixedly connected to the main cabinet and the other side slidably connected to the two sets of auxiliary cabinets for assisting in the movement of the auxiliary cabinets.

[0008] Furthermore, two L-shaped grooves are symmetrically opened on the top of the dustproof plate; a connecting strip is provided above each of the two auxiliary cabinets, and the top of the connecting strip passes through the L-shaped groove to fix and connect to the limiting block.

[0009] Furthermore, the limiting mechanism includes two sets of limiting units arranged longitudinally along the main cabinet; each limiting unit includes a hollow strip, an L-shaped strip, an L-shaped block, a limiting rod one, and a limiting rod two; the hollow strip is fixed to the side of the main cabinet away from the auxiliary cabinet; each set of limiting units has two L-shaped strips, both arranged along the corner of the main cabinet, with one end inserted into the hollow strip from both ends, slidably connected to the hollow strip, and limited by the limiting rod two; the other end of the L-shaped strip is slidably connected to a convex slider fixedly arranged on the auxiliary cabinet, and limited by the limiting rod one.

[0010] Furthermore, two sets of limiting rods are provided, respectively located on both sides of the hollow strip; one end of the limiting rod passes through the circular hole on the hollow strip, and the other end is fitted with a spring; the spring is fixedly connected to the limiting rod and the hollow strip respectively; the L-shaped strip has multiple circular holes at equal intervals on one end inserted into the hollow strip, corresponding to the circular holes on the hollow strip, for setting the limiting rod.

[0011] Furthermore, two sets of convex sliders are fixedly installed on the outer sides of the two sets of auxiliary cabinets, arranged longitudinally along the auxiliary cabinets; the convex sliders are shaped to match the L-shaped strips and are slidably connected to the L-shaped strips; two L-shaped blocks are fixedly connected to the auxiliary cabinets on the upper part of the convex sliders; one end of the limiting rod passes through the round hole on the L-shaped block, and the other end is fitted with a spring; the spring is fixedly connected to the limiting rod and the L-shaped block respectively; the convex sliders are provided with round holes corresponding to the round holes on the L-shaped blocks; multiple positioning holes corresponding to the round holes on the L-shaped blocks are equidistantly arranged on the end of the L-shaped strip that matches the convex sliders.

[0012] Furthermore, the lifting mechanism includes a guide rod, a lead screw, and a motor; both the guide rod and the lead screw pass through the movable plate; the guide rod is slidably connected to the movable plate; the lead screw is threadedly connected to the movable plate; the motor is fixedly installed above the mounting cabinet; the output end of the motor passes through the upper wall of the mounting cabinet and is fixedly connected to the upper end of the lead screw.

[0014] Furthermore, one side of the main cabinet is provided with an operation panel, and one side of the auxiliary cabinet is provided with an operation panel.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. This utility model allows the limiting rod two to be pulled outwards by hand, disengaging it from the inside of the round hole and releasing the L-shaped strip from its restriction. At this point, the L-shaped strip can slide outwards along the inside of the hollow strip, simultaneously moving the auxiliary cabinet to one side. Then, the limiting rod two is released, allowing it to be inserted into the other round hole under the restoring force of the spring two, thus restricting the L-shaped strip. Next, the limiting rod one is pulled upwards by hand, disengaging it from the positioning hole and releasing the restriction on the convex slider. Simultaneously, the spring one is stretched, allowing the convex slider to slide outwards along the inside of the L-shaped strip. The main cabinet slides to one side, simultaneously moving the auxiliary cabinet to the same side to keep it on the same horizontal line as the main cabinet. Then, the first limit rod is released, allowing it to be inserted into another positioning hole under the restoring force of the first spring, limiting the convex slider and keeping the auxiliary cabinet and main cabinet in a relatively fixed state. This prevents the auxiliary cabinet from rotating if the back of the auxiliary cabinet is accidentally bumped, thus preventing collisions between the auxiliary cabinet and the main cabinet and avoiding damage to the electrical components on both cabinets. This ensures that trainees can successfully simulate and troubleshoot abnormal line losses in the distribution area.

[0017] 2. This utility model allows the connecting strip to move along the L-shaped slide groove by moving the auxiliary cabinet. First, it moves left and right, and then it moves forward and backward. With the cooperation of the limiting block, a vertical limit can be applied to the connecting strip and the auxiliary cabinet, which assists in the movement of the auxiliary cabinet. This provides a support effect for the auxiliary cabinet, thereby improving the stability of the movement of the auxiliary cabinet. Attached Figure Description

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.

[0026] Please see the appendix Figure 1-4This utility model provides a teaching device for simulating and troubleshooting abnormal line loss in a transformer substation, including a mounting cabinet 1, which is hollow inside. The mounting cabinet 1 contains a main cabinet 102 and two auxiliary cabinets 103, with the two auxiliary cabinets 103 mounted on a movable plate 101 fixedly mounted at the bottom of the main cabinet 102. The auxiliary cabinets 103 are movably connected to the main cabinet 102 via a limiting mechanism. The top of the mounting cabinet 1 has a through-slot for the main cabinet 102 and auxiliary cabinets 103 to pass through. The upper end of the movable plate 101 passes through the through-slot, and the lower end is slidably mounted inside the mounting cabinet 1. A lifting mechanism is connected to the lower part of the movable plate 101 for lifting the main cabinet 102 and auxiliary cabinets 103.

[0027] The main cabinet 102 is also equipped with a dustproof plate 3 on its top. One side of the bottom of the dustproof plate 3 is fixedly connected to the main cabinet 102, and the other side is slidably connected to two sets of auxiliary cabinets 103 for assisting in the movement of the auxiliary cabinets 103.

[0028] The top of the main cabinet 102 is symmetrically and fixedly connected to two columns 305, and the top of the two columns 305 is fixedly connected to a dustproof plate 3. The dustproof plate 3 provides a certain dustproof effect.

[0029] The dustproof plate 3 has two symmetrically arranged L-shaped grooves 302 on its top; each of the two auxiliary cabinets 103 is provided with a connecting strip 304, the top of which passes through the L-shaped groove 302 and is fixedly connected to a limiting block 303. The connecting strip 304 slides inside the L-shaped groove 302. With the movement of the auxiliary cabinet 103, the connecting strip 304 can be driven to move along the L-shaped groove 302, first moving left and right, and then moving forward and backward. With the cooperation of the limiting block 303, a vertical limit can be applied to the connecting strip 304 and the auxiliary cabinet 103, thus assisting the movement of the auxiliary cabinet 103.

[0030] The limiting mechanism includes two sets of limiting units arranged longitudinally along the main cabinet 102; the limiting unit includes a hollow strip 205, an L-shaped strip 2, an L-shaped block 203, a limiting rod 1 202 and a limiting rod 206; the hollow strip 205 is fixedly arranged on the side of the main cabinet 102 away from the auxiliary cabinet 103.

[0031] Two L-shaped bars 2 are provided in each set of limiting units, which are set along the corners of the main cabinet 102. One end of each bar is inserted into the hollow bar 205 from both ends and slidably connected to the hollow bar 205, and is limited by the second limiting rod 206. The other end of the L-shaped bar 2 is slidably connected to the convex slider 208 fixedly provided on the auxiliary cabinet 103, and is limited by the first limiting rod 202.

[0032] Two sets of limiting rods 206 are provided, respectively located on both sides of the hollow strip 205. One end of the limiting rod 206 passes through a circular hole on the hollow strip 205, and the other end is fitted with a spring 207. The spring 207 is fixedly connected to the limiting rod 206 and the hollow strip 205. The L-shaped strip 2 has multiple circular holes at equal intervals on one end inserted into the hollow strip 205, corresponding to the circular holes on the hollow strip 205, for setting the limiting rod 206. One end of the limiting rod 206 is located in the circular hole. By pulling the limiting rod 206, the end of the limiting rod 206 inserted into the circular hole can be disengaged from the L-shaped strip 2, releasing the limiting of the L-shaped strip 2. After moving the L-shaped strip 2, under the restoring force of the spring 207, the limiting rod 206 can be inserted into the other circular hole to limit the L-shaped strip 2.

[0033] Two sets of convex sliders 208 are fixedly installed on the outer sides of the two sets of auxiliary cabinets 103, arranged longitudinally along the auxiliary cabinets 103; the convex sliders 208 are shaped to match the L-shaped strips 2 and are slidably connected to the L-shaped strips 2; two L-shaped blocks 203 are fixedly connected to the auxiliary cabinets 103 on the upper part of the convex sliders 208; one end of the limiting rod 202 passes through the round hole on the L-shaped block 203, and the other end is fitted with a spring 204; the spring 204 is fixedly connected to the limiting rod 202 and the L-shaped block 203 respectively; the convex sliders 208 are provided with round holes corresponding to the round holes on the L-shaped blocks 203; multiple positioning holes 201 corresponding to the round holes on the L-shaped blocks 203 are equidistantly arranged on the end of the L-shaped strip 2 that matches the convex sliders 208. By pulling the limiting rod 202, one end of the limiting rod 202 inserted into the positioning hole 201 can be disengaged from the L-shaped strip 2, thus releasing the limiting of the L-shaped strip 2; after moving the L-shaped strip 2, under the restoring force of the spring 204, the limiting rod 202 can be inserted into another positioning hole 201 to limit the L-shaped strip 2.

[0034] The lifting mechanism includes a guide rod 106, a lead screw 105, and a motor 107.

[0035] The guide rod 106 is vertically positioned on one side inside the mounting cabinet 1, and the lead screw 105 is vertically positioned on the side inside the mounting cabinet 1 away from the guide rod 106. Both the guide rod 106 and the lead screw 105 pass through the movable plate 101. The guide rod 106 is slidably connected to the movable plate 101, and the lead screw 105 is threadedly connected to the movable plate 101. The motor 107 is fixedly installed above the mounting cabinet 1. The output end of the motor 107 passes through the upper wall of the mounting cabinet 1 and is fixedly connected to the upper end of the lead screw 105. The movable plate 101 can slide up and down along the guide rod 106, synchronously driving the main cabinet 102 to move up and down. The controller controls the motor 107 to start, causing its output shaft to drive the lead screw 105 to rotate. Then, under the action of the threaded connection between the lead screw 105 and the movable plate 101, and with the cooperation of the guide rod 106 in limiting and guiding the movable plate 101, the movable plate 101 can move up and down along the outer surface of the lead screw 105.

[0036] The dustproof plate 3 has an opening slot 301 on one side, and the top of the mounting cabinet 1 has two opening slots 104 symmetrically arranged. The opening slot 301 allows the motor 107 to be avoided when the dustproof plate 3 comes into contact with the mounting cabinet 1; the opening slots 104 facilitate the movement of the limiting rod 206 through the opening slots 104 into or out of the mounting cabinet 1.

[0037] The main cabinet 102 has an operation panel 1 on one side, and the auxiliary cabinet 103 has an operation panel 2 on one side. These settings facilitate trainees in simulating and troubleshooting abnormal line losses in the transformer area.

[0038] Working principle: In use, the controller starts the motor 107, which drives the lead screw 105 to rotate. Then, under the action of the threaded connection between the lead screw 105 and the movable plate 101, and with the cooperation of the guide rod 106 to limit and guide the movable plate 101, the movable plate 101 can move up and down along the outer surface of the lead screw 105, which simultaneously drives the main cabinet 102 and auxiliary cabinet 103 to move up and down. The main cabinet 102 and auxiliary cabinet 103 can be stored in the installation cabinet 1, and the dustproof plate 3 is in contact with the top of the installation cabinet 1 to prevent dust from entering the installation cabinet 1. Similarly, the main cabinet 102 and auxiliary cabinet 103 can be moved out of the installation cabinet 1. After the main cabinet 102 and auxiliary cabinet 103 are raised, the limiting rod 206 is pulled outward by hand to disengage it from the inside of the round hole, thus releasing the limiting of the L-shaped strip 2. At this time, the L-shaped strip 2 can slide outward along the inside of the hollow strip 205, simultaneously driving the auxiliary cabinet 103 to move to one side. Then, the limiting rod 206 is released, and under the restoring force of the spring 207, it is reinserted into the inside of another round hole to limit the L-shaped strip 2. Next, by manually pulling the limiting rod 202 upward, it is disengaged from the positioning hole 201, releasing the limitation on the convex slider 208. At this time, the convex slider 208 can slide to one side along the inside of the L-shaped strip 2, simultaneously driving the auxiliary cabinet 103 to move to one side, so that the auxiliary cabinet 103 and the main cabinet 102 are on the same horizontal line. Then, the limiting rod 202 is released, and under the reset force of the spring 204, it is inserted into another positioning hole 201 to limit the convex slider 208, so that the auxiliary cabinet 103 and the main cabinet 102 are kept in a relatively fixed state. In this way, when the back of the auxiliary cabinet 103 is accidentally bumped, it can prevent the auxiliary cabinet 103 from rotating, thereby preventing the auxiliary cabinet 103 from colliding with the main cabinet 102 and avoiding damage to the electrical components on the auxiliary cabinet 103 and the main cabinet 102. This ensures that trainees can successfully simulate and troubleshoot abnormal line loss in the distribution area. Simultaneously, by moving the auxiliary cabinet 103, the connecting bar 304 can be moved along the L-shaped slide 302, first moving left and right, and then moving forward and backward. With the cooperation of the limit block 303, a vertical limit can be applied to the connecting bar 304 and the auxiliary cabinet 103, assisting the movement of the auxiliary cabinet 103. This provides a support effect for the auxiliary cabinet 103, thereby improving the stability of the movement of the auxiliary cabinet 103.
