A grounding fault detection alarm for power transmission lines Technical Field

[0001] This utility model belongs to the technical field of power transmission line fault alarm devices, specifically a power transmission line grounding fault detection alarm device. Background Technology

[0002] Power transmission lines are constructed by using transformers to step up the voltage of electricity generated by generators, which is then transmitted to the power lines via circuit breakers and other control equipment. Power transmission lines are classified into overhead transmission lines and cable lines based on their structure. Overhead transmission lines consist of towers, conductors, insulators, line hardware, guy wires, tower foundations, and grounding devices, and are erected above the ground. Based on the nature of the current transmitted, power transmission is divided into AC transmission and DC transmission. Power transmission lines are highly susceptible to failure during their installation and use.

[0003] A search revealed that patent CN218445924U discloses a power transmission line grounding fault detection and alarm device, including a circuit fault detector. The circuit fault detector has two symmetrically fixed brackets on its top wall. A through hole is formed between the two side walls of the brackets, and a connecting shaft is rotatably connected to the inner wall of the through hole. A speaker is positioned above one side of the front wall of the circuit fault detector. The two connecting shafts are symmetrically arranged, and a wireless display is fixedly connected between their opposing side walls. This invention features a well-designed power transmission line grounding fault detection and alarm feedback structure. The circuit fault detector can be connected to the power transmission line via two detection connectors and detection lines to perform grounding fault detection and alarm functions. Fault information can be fed back via the wireless display, and alarm sounds can be emitted via the speaker, providing comprehensive alarm information feedback.

[0004] However, the wireless display in the aforementioned patent is exposed to the outside world and lacks protection, making it easy to be damaged if it is accidentally bumped. Summary of the Invention

[0027] Referring to Figures 1-4, a transmission line grounding fault detection alarm device provided by an embodiment of this utility model will now be described. A transmission line grounding fault detection alarm device includes a circuit fault detector 1. A speaker 101 is provided on the upper side of the front end face of the circuit fault detector 1. Guide plates 2 are fixedly connected to both sides of the circuit fault detector 1. Support plates 7 are slidably connected to both guide plates 2. Mounting shafts 9 are rotatably connected to both support plates 7. A wireless display 10 is fixedly connected between the two mounting shafts 9. A display screen 11 is fixedly installed on the outer wall of the wireless display 10. A sliding groove 3 is formed in the support plate 7. The support plate 7 has a sliding plate 4, and a locking rod 5 is fixedly connected inside the sliding plate 4. The support plate 7 has locking holes 8 near the top and bottom. The locking rod 5 is slidably fitted into the locking holes 8. When the locking rod 5 is fitted into the locking hole 8 at the top, the support plate 7 can be pulled out and fixed. After the wireless display 10 is rotated and unfolded, the support plate 7 can be fixed when the wireless display 10 is pressed against the circuit fault detector 1 by fitting the locking rod 5 into the locking hole 8 at the bottom, so that the wireless display 10 is stably pressed onto the circuit fault detector 1.

[0028] The present invention provides a grounding fault detection alarm for power transmission lines. Compared with the prior art, it can fasten one side of the display screen 11 of the wireless display 10 to the top surface of the circuit fault detector 1, thereby protecting it from accidental collisions that could cause scratches.

[0029] In another embodiment of this utility model, please refer to Figure 3. Slide rods 12 are fixedly connected to the front end of the wireless display 10 near the outer walls on both sides. Slider blocks 13 are slidably connected to the outer walls of the two slide rods 12. A mounting plate 14 is fixedly connected between the two slider blocks 13. A cleaning brush 15 is fixedly connected to the mounting plate 14. The two slide rods 12 are respectively set on both sides of the display screen 11. One end of the cleaning brush 15 is attached to the surface of the display screen 11 to facilitate cleaning dust from the surface of the display screen 11. A handle is fixedly connected to the outer wall of one of the slider blocks 13. The cleaning brush 15 is made of antistatic nylon, and its surface is not easy to adhere to dust. The handle makes it easy to move the mounting plate 14 up and down by hand.

[0030] In another embodiment of this utility model, please refer to Figures 1 and 2. A handle 16 is fixedly connected to two mounting shafts 9. The display screen 11 is disposed on the surface of the wireless display 10 away from the handle 16. By holding the handle 16, it is convenient to carry this utility model. When the handle 16 is in use, it can limit the support plate 7 when the locking rod 5 is engaged in the locking hole 8, so that the fixing plate for mounting the slide rod 12 is pressed against the top surface of the circuit fault detector 1, thereby limiting the rotation of the circuit fault detector 1 relative to the handle 16, making this utility model more stable when carried.

[0031] In another embodiment of this utility model, please refer to Figures 3 and 4. A spring 6 is fixedly connected between the slide plate 4 and the slide groove 3. The spring 6 is movably sleeved on the outer end of the locking rod 5. The spring 6 can prevent the locking rod 5 from sliding out of the locking hole 8, thus losing the fixing effect on the support plate 7. One end of the locking rod 5 passes through the guide plate 2 and is fixedly connected to a round cap. The rotational friction between the mounting shaft 9 and the support plate 7 is greater than the weight of the wireless display 10. Increasing the rotational friction of the mounting shaft 9 can keep the display screen 11 stable when the wireless display 10 is lifted, avoiding deflection under the action of gravity. The lower ends of the two support plates 7 are fixedly connected to limit plates. The straight-line height of the limit plate from the locking hole 8 is equal to the straight-line height of the locking rod 5 from the lower end surface of the guide plate 2. The upper end surface area of ​​the two limit plates is greater than the bottom surface area of ​​the support plate 7. The limit plates are used to limit the maximum rising distance of the support plate 7. At the same time, since the locking hole 8 is directly opposite the locking rod 5 when the limit plate is attached to the guide plate 2, it is convenient to limit the movement.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
