Description

Technical Field

[0001] This utility model relates to the field of line loss analysis technology, specifically to a power line loss analysis device. Background Technology

[0002] Line loss, or line loss for short, is the energy loss that occurs when electrical energy is transmitted through transmission lines. It is caused by the loss of active power during power transmission and mainly consists of three parts: first, active power loss due to current flowing through resistive conductors; second, active power loss due to leakage current in the insulation between lines and connections due to voltage on the line; and third, active power loss due to corona discharge in the energized parts of overhead transmission lines. To prevent excessive line loss from causing power loss and waste, after a rough calculation at the terminal, a line loss analyzer is used to analyze and record suspicious power lines. The analyzer collects data, performs comprehensive calculations, and then transmits the signals to the main control system for monitoring, facilitating the analysis and identification of power grid faults and enabling timely and effective measures. However, existing line loss analyzers are easily affected by loose connections, which can impact the analysis results. Furthermore, most are limited to handheld operation, requiring the analyzer to be placed on the ground when handheld operation is not possible, making them inconvenient to use. Moreover, vibration during transport can damage the internal components. Therefore, we propose a power line loss analysis device. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the existing defects and provide a power line loss analysis device that facilitates the disassembly of the analyzer housing and the adjustment of the tilt angle of the analyzer housing, making the analysis more convenient. The connection of the connecting wires is more secure, which can avoid the influence of analysis data due to loose connection during analysis. It can also play a role in shock absorption and protection of the analyzer housing to prevent damage to the internal mechanism, and can effectively solve the problems in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a power line loss analysis device, comprising a protective housing and an adjustment mechanism;

[0005] Protective casing: The rear end of the casing is hinged to a lid, the front side of the casing has a slot that matches the lid, the inside left end of the casing has a placement slot, and the middle of the casing has an installation slot.

[0006] Adjustment mechanism: It includes a connecting rod, which is rotatably connected to the front end of the mounting slot. The left end of the connecting rod extends into the placement slot and is fixedly connected to an L-shaped plate. The upper surface of the L-shaped plate is fitted with an analyzer housing. An analyzer panel is provided at the upper end of the inside of the analyzer housing. Analyzer interfaces are symmetrically provided on the rear side of the analyzer housing, which facilitates the disassembly of the analyzer housing and the adjustment of the tilt angle of the analyzer housing, making analysis more convenient. The connection of the connecting wires is more secure, which can avoid the influence of analysis data due to loose connections during analysis. It can also play a role in shock absorption and protection of the analyzer housing to prevent damage to the internal mechanism.

[0007] Furthermore, the L-shaped plate has symmetrically arranged bayonets in the middle, and the lower surface of the analyzer housing has symmetrically arranged locking strips that engage with the bayonets, facilitating the disassembly of the analyzer housing.

[0008] Furthermore, springs are symmetrically arranged inside the placement groove, and the upper ends of the two springs are fixedly connected to the top plate. The upper surface of the top plate is arc-shaped and contacts the lower surface of the L-shaped plate, providing elastic support for the L-shaped plate.

[0009] Furthermore, a lever is provided at the right end of the connecting rod, and an arc-shaped rod is provided on the lower surface of the lever. The arc-shaped rod is concentric with the connecting rod, and elastic blocks are symmetrically provided on the outer side of the arc-shaped rod. The front and rear inner walls of the mounting groove are provided with protrusions at the same angle to cooperate with the elastic blocks, so as to facilitate the adjustment of the tilt angle of the L-shaped plate.

[0010] Furthermore, a baffle is slidably connected in the groove provided in the middle of the upper surface of the protective shell. The rear side of the baffle is fixedly connected to the inner wall of the groove by a spring piece. The baffle is configured to cooperate with the convex shaft at the rear end of the lever to limit the lever.

[0011] Furthermore, a storage slot is provided at the right end of the inner side of the protective shell. A U-shaped frame is rotatably connected inside the storage slot. Both ends of the U-shaped frame are fixedly connected to the inner wall of the storage slot by torsion springs, which facilitates the storage of the connecting wires.

[0012] Furthermore, the upper surface edge of the protective shell is provided with a stepped surface that mates with the lid, and a sealing strip is provided on the upper surface of the stepped surface to seal the connection between the protective shell and the lid.

[0013] Furthermore, the inner top wall of the box cover is provided with a pressure block corresponding to the analyzer housing. The inside of the pressure block is honeycomb-shaped, which serves to limit the position of the analyzer housing.

[0014] Furthermore, clamps are provided at the edges of the analyzer interface, and notches are evenly provided at the rear opening of the clamps. The rear end of the outer side of the clamp is beveled, and an internal threaded ring is threaded to the outer side of the clamp to avoid affecting the analysis data due to loose connection during analysis.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This power line loss analysis device has the following advantages:

[0016] 1. Push the baffle backward along the slide groove. The spring is squeezed. At this time, under the action of the spring force, the top plate pushes the L-shaped plate upward, so that the L-shaped plate rotates around the connecting rod at a certain angle. At the same time, the lever at the right end of the connecting rod rotates synchronously. At this time, the angle of the L-shaped plate can be adjusted by rotating the connecting rod through the lever. During adjustment, the arc-shaped rod at the lower end of the lever rotates around the connecting rod. The elastic block on the outer side of the arc-shaped rod contacts the convex strip and undergoes elastic deformation. When the adjustment stops, the convex strip plays a limiting role on the elastic block, thereby limiting and fixing the connecting rod and the L-shaped plate. When in use, the analyzer housing can automatically pop out, which also makes it convenient to adjust the tilt angle of the analyzer housing, which is convenient for subsequent analysis and testing.

[0017] 2. Slide the latch on the lower surface of the analyzer housing backward along the latch to remove the analyzer housing, making it easy to hold the analyzer housing for analysis. After use, reset the L-shaped plate using the lever. The spring provides elastic support and shock absorption for the analyzer housing, preventing damage to the internal mechanism.

[0018] 3. Connect the connecting wire to the test line, then rotate the internal threaded ring to move it backward. The internal threaded ring engages with the beveled surface at the rear end of the clamp to reduce the opening at the rear end of the clamp, thereby fixing the connecting wire and making the connection more secure. This prevents the analysis data from being affected by a loose connection during analysis. 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.

[0027] Please see Figure 1-6 This utility model provides a technical solution: a power line loss analysis device includes a protective shell 1 and an adjustment mechanism 2;

[0028] Protective outer shell 1: Its rear end is hinged to a box cover 3. The front side of the protective outer shell 1 is provided with a slot 4 that mates with the box cover 3. The latch at the front end of the box cover 3 engages with the slot 4 to fix the box cover 3. The left end of the interior of the protective outer shell 1 is provided with a placement slot 5. The middle of the protective outer shell 1 is provided with an installation slot 6 to provide an installation place for the internal structure. The upper edge of the protective outer shell 1 is provided with a stepped surface that mates with the box cover 3. A sealing strip 11 is provided on the upper surface of the stepped surface to ensure the sealing of the connection between the box cover 3 and the protective outer shell 1.

[0029] Adjustment mechanism 2 includes a connecting rod 24, which is rotatably connected to the front end of the mounting groove 6. The left end of the connecting rod 24 extends into the placement groove 5 and is fixedly connected to the L-shaped plate 8. The upper surface of the L-shaped plate 8 is fitted with an analyzer housing 9. The inner top wall of the cover 3 is provided with a pressure block 31 corresponding to the analyzer housing 9. The interior of the pressure block 31 is honeycomb-shaped and serves to limit the position of the analyzer housing 9. The upper interior of the analyzer housing 9 is provided with an analyzer panel 91. The rear side of the analyzer housing 9 is symmetrically provided with analyzer interfaces 92. Each edge of the analyzer interface 92 is provided with a clamp 14. The rear end opening of the clamp 14 is evenly provided with notches, and the rear end of the outer side of the clamp 14 is beveled. The outer surface of the clamp 14 is threaded with an internal threaded ring 15. A bayonet 81 is symmetrically arranged in the middle of the L-shaped plate 8. A locking strip 93, which engages with the bayonet 81, is symmetrically arranged on the lower surface of the analyzer housing 9. The connecting wire is inserted into the analyzer interface 92 at the rear end of the analyzer housing 9, and connected to the circuit being tested. Then, the internal threaded ring 15 is rotated, causing it to move backward. The internal threaded ring 15 engages with the inclined surface at the rear end of the clamp 14, narrowing the opening at the rear end of the clamp 14 and thus fixing the connecting wire. At this time, the various line losses of the circuit can be analyzed and recorded through the analyzer panel 91. The locking strip 93 on the lower surface of the analyzer housing 9 can also be slid backward along the bayonet 81 to secure the analyzer. The housing 9 is removed for easy handheld analysis. Springs 10 are symmetrically arranged on the inner surface of the placement slot 5. The upper ends of both springs 10 are fixedly connected to the top plate. The upper surface of the top plate is arc-shaped and contacts the lower surface of the L-shaped plate 8. A lever 21 is located at the right end of the connecting rod 24. An arc-shaped rod 22 is located on the lower surface of the lever 21, concentrically positioned with the connecting rod 24. Elastic blocks 23 are symmetrically arranged on the outer side of the arc-shaped rod 22. Protrusions 61 that cooperate with the elastic blocks 23 are arranged at the same angle on the front and rear inner walls of the mounting slot 6. A baffle 12 is slidably connected within a groove located in the middle of the upper surface of the protective housing 1. The rear side of the baffle 12 is fixed to the inner wall of the groove via a spring piece 13. The connection is made so that the baffle 12 and the convex shaft at the rear end of the lever 21 are engaged. When the baffle 12 is pushed backward along the slide groove, the spring piece 13 is squeezed. At this time, under the elastic force of the spring 10, the top plate pushes the L-shaped plate 8 upward, so that the L-shaped plate 8 rotates around the connecting rod 24 at a certain angle. At the same time, the lever 21 at the right end of the connecting rod 24 rotates synchronously. At this time, the angle of the L-shaped plate 8 can be adjusted by rotating the connecting rod 24 through the lever 21. During adjustment, the arc-shaped rod 22 at the lower end of the lever 21 rotates around the connecting rod 24. The elastic locking block 23 on the outer side of the arc-shaped rod 22 contacts the protrusion 61 and undergoes elastic deformation. When the adjustment stops, the protrusion 61 plays a limiting role on the elastic locking block 23, thereby limiting and fixing the connecting rod 24 and the L-shaped plate 8.

[0030] The protective casing 1 has a storage slot 7 on its right side. A U-shaped frame 71 is rotatably connected inside the storage slot 7. Both ends of the U-shaped frame 71 are fixedly connected to the inner wall of the storage slot 7 by torsion springs. When the U-shaped frame 71 inside the storage slot 7 is lifted upward, the torsion spring is stressed and the connecting wire is placed inside the storage slot 7. When the U-shaped frame 71 is released, the connecting wire inside the storage slot 7 is pressed and fixed by the elastic force of the torsion spring.

[0031] In use: Lift the lid 3 upwards to separate the latch at the front of the lid 3 from the slot 4 at the front of the protective shell 1. Push the baffle 12 backwards along the slide groove, compressing the spring 13. At this time, under the elastic force of the spring 10, the top plate pushes the L-shaped plate 8 upwards, causing the L-shaped plate 8 to rotate around the connecting rod 24 at a certain angle. Simultaneously, the lever 21 at the right end of the connecting rod 24 rotates synchronously. Rotating the connecting rod 24 by the lever 21 allows adjustment of the angle of the L-shaped plate 8. During adjustment, the arc-shaped rod 22 at the lower end of the lever 21 rotates around the connecting rod 24. 2. The outer elastic block 23 contacts the protrusion 61 and undergoes elastic deformation. When adjustment stops, the protrusion 61 limits the elastic block 23, thereby limiting and fixing the connecting rod 24 and the L-shaped plate 8. At this time, the connecting wire is inserted into the analyzer interface 92 at the rear end of the analyzer housing 9, and the connecting wire is connected to the detection line. Then, the internal threaded ring 15 is rotated to move the internal threaded ring 15 backward. The internal threaded ring 15 cooperates with the inclined surface at the rear end of the clamp 14 to reduce the opening at the rear end of the clamp 14, thereby fixing the connecting wire. At this time, the analyzer... Panel 91 allows for the analysis and recording of various line losses. The analyzer housing 9 can also be removed by sliding the retaining strip 93 along the retaining groove 81 on the lower surface of the analyzer housing 9, facilitating handheld analysis. After use, reverse the internal threaded ring 15 to remove the connecting wire. Lift the U-shaped bracket 71 inside the storage slot 7 upwards; the torsion spring will then be engaged, allowing the connecting wire to be placed inside the storage slot 7. Release the U-shaped bracket 71; under the elastic force of the torsion spring, the U-shaped bracket 71 will hold and fix the connecting wire inside the storage slot 7. Then, remove the analyzer housing. Body 9 is snapped onto the upper surface of L-shaped plate 8. L-shaped plate 8 is reset by lever 21. Under the elastic force of spring piece 13, baffle 12 is reset to limit and fix lever 21. Spring 10 can provide elastic support. Then, box cover 3 is reset. The latch at the front end of box cover 3 engages with slot 4 to fix box cover 3. Pressure block 31 inside box cover 3 contacts analyzer housing 9 to limit analyzer housing 9. Analyzer housing 9 can ensure the sealing of the connection between box cover 3 and protective shell 1 and play an anti-slip role for internal structure.

[0032] It is worth noting that the analyzer panel 91 disclosed in this embodiment is recommended to be the control panel inside the HTXS-1 analyzer.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
