Description

Technical Field

[0001] This utility model belongs to the field of leakage current warning technology, specifically relating to a composite insulator leakage current warning device. Background Technology

[0002] Composite insulators, also known as non-ceramic insulators or polymer insulators, are electrical insulation devices composed of two or more different materials (mainly polymer materials and glass fiber). They are primarily used in power systems, such as transmission lines and substations, to provide both electrical insulation and mechanical fixation.

[0003] When current composite insulators experience leakage during long-term use, this situation is often difficult to detect due to their high installation location, thus increasing the difficulty of inspection and replacement. Utility Model Content

[0004] The purpose of this invention is to provide a composite insulator leakage warning device to solve the problem that in the prior art, composite insulators installed at high locations are not easy to detect, and leakage is difficult to detect.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A composite insulator leakage warning device includes an insulator body and an L-shaped mounting base installed at the bottom of the insulator body. A hanging rod is installed on the inner top of the L-shaped mounting base, and a detection component is connected to the lower end of the hanging rod. An alarm is installed on the top of the detection component, and a pressure sensor is installed at the bottom of the alarm. The detection component is used to monitor the current on the L-shaped mounting base.

[0007] Preferably, the detection component includes a housing, in which a first transmission cavity and a second transmission cavity are sequentially arranged. A vertical groove communicating with the second transmission cavity is opened on the top of the housing, and an installation groove communicating with the first transmission cavity is opened in the housing. An iron core is arranged in the installation groove, and a coil is sleeved outside the iron core. Both ends of the coil extend outward through the front side of the housing.

[0008] Preferably, conductive plates are connected to both ends of the outer shell after protruding from the outer shell, and both conductive plates are fixedly connected to the side of the L-shaped mounting base by soldering.

[0009] Preferably, the detection assembly further includes a top rod inserted and slidably connected in the vertical groove. The lower end of the top rod extends into the second transmission cavity and is connected to a wedge block. A magnet is slidably installed in the first transmission cavity. The end of the magnet facing away from the iron core is connected to an inclined top block. The inclined top block passes through the first transmission cavity, extends into the second transmission cavity, and is set against the inclined surface of the wedge block.

[0010] Preferably, a support spring is installed on the inner side of the first transmission cavity, and the end of the support spring facing away from the wedge block is fixedly connected to the magnet.

[0011] Preferably, the top rod is an insulating rubber rod to prevent it from interfering with the normal operation of the alarm after it becomes conductive.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When the insulator body leaks current, the current is conducted to the L-shaped mounting base, the coil will come into contact with the current, the iron core will be energized and become magnetic, which will push the magnet, thereby driving the inclined top block to push the wedge block, and finally causing the top rod to press the pressure sensor, realizing the self-alarm setting of the alarm, so that the ground personnel can be notified at the first time when the insulator body leaks current, and the purpose of rapid inspection and replacement of the insulator body can be achieved.

[0014] 2. This utility model can quickly alarm after leakage occurs in the insulator body through ingenious design, eliminating the need for personnel to climb to height for inspection and maintenance, improving the safety of the insulator body, and is practical and reliable.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Reference Figure 1 , Figure 2 As shown, this utility model provides a composite insulator leakage early warning device, including an insulator body 1 and an L-shaped mounting base 2 installed at the bottom of the insulator body 1. A hanging rod 3 is installed on the inner top of the L-shaped mounting base 2, and a detection component 4 is connected to the lower end of the hanging rod 3. An alarm 5 is installed on the top of the detection component 4, and a pressure sensor 51 is installed at the bottom of the alarm 5. The detection component 4 is used to monitor the current on the L-shaped mounting base 2. Thus, through clever design, a rapid alarm can be achieved after leakage occurs in the insulator body 1, eliminating the need for personnel to climb to a height for inspection and improving the safety of the insulator body 1.

[0023] In a further embodiment, refer to Figures 2-4 The detection component 4 includes a housing 42, inside which a first transmission cavity 421 and a second transmission cavity 422 are arranged in sequence. The top of the housing 42 is provided with a vertical groove 423 that communicates with the second transmission cavity 422, and the housing 42 is provided with a mounting groove 424 that communicates with the first transmission cavity 421. An iron core 45 is provided in the mounting groove 424, and a coil 43 is sleeved on the outside of the iron core 45. Using the principle of electromagnetism, both ends of the coil 43 extend outward through the front side of the housing 42.

[0024] The two ends of the outer shell 42 extend out of the outer shell 42 and are connected to the conductive plates 44. Both conductive plates 44 are fixedly connected to the side of the L-shaped mounting base 2 by soldering. When the insulator body 1 leaks current, the current is conducted to the L-shaped mounting base 2. Through the connection of the conductive plates 44, the coil 43 will come into contact with the current.

[0025] In this embodiment, when the coil 43 is energized, the iron core 45 becomes magnetic, thereby driving the magnet 46.

[0026] In a further embodiment, refer to Figure 3 and Figure 4The detection component 4 also includes a push rod 41 inserted and slidably connected in the vertical groove 423. The lower end of the push rod 41 extends into the second transmission cavity 422 and is connected to a wedge block 49. A magnet 46 is slidably installed in the first transmission cavity 421. The end of the magnet 46 facing away from the iron core 45 is connected to an inclined push block 47. The inclined push block 47 extends through the first transmission cavity 421 into the second transmission cavity 422 and is set against the inclined surface of the wedge block 49. This allows the wedge block 49 to be pushed upward when the inclined push block 47 moves away from the iron core 45. A support spring 48 is installed on the inner side of the first transmission cavity 421. The end of the support spring 48 facing away from the wedge block 49 is fixedly connected to the magnet 46. The support spring 48 provides a supporting force to the magnet 46 when it is not subjected to the magnetic pushing force of the iron core 45.

[0027] In addition, the top rod 41 is an insulating rubber rod product to prevent interference with the normal operation of the alarm 5 after it becomes conductive, and also to prevent damage to the alarm 5 caused by excessive impact.

[0028] In this embodiment, when the insulator body 1 leaks current, the current is conducted to the L-shaped mounting base 2, the coil 43 will come into contact with the current, the iron core 45 will be energized and become magnetic, which will push the magnet 46, thereby driving the inclined top block 47 to push the wedge block 49, and finally causing the top rod 41 to press the pressure sensor 51, realizing the self-alarm setting of the alarm 5, thereby achieving the purpose of rapid inspection and replacement of the insulator body 1.
