Description

Technical Field

[0001] The present invention relates to the field of electric power technology, and in particular to a porcelain bottle monitoring device. Background Art

[0002] Insulators are used on overhead line towers and transmission and distribution lines. They serve two primary functions: first, to firmly support and secure the conductors; second, to provide effective insulation between the conductors and the ground. Commonly used insulators are subject to significant pressure and load-bearing capacity at high altitudes. Overvoltage and surface contamination can easily degrade the insulation performance of insulators, leading to discharge damage and eventual complete loss of insulation. Lightning strikes in summer and autumn are a major cause of damage to insulators. The induced overvoltage and high voltage generated by direct lightning strikes on conductors far exceed the actual operating voltage of the insulators. Repeated overload operation eventually destroys the insulation performance of the insulators. Because the insulators are located atop the towers, each line inspection requires climbing the towers to inspect their appearance, which is time-consuming and laborious. Furthermore, the large number of towers makes line inspections labor-intensive.

[0003] In the process of realizing the present invention, the inventors found that defects in porcelain bottles can only be detected by manual inspection, by visual inspection, or by taking photos with drones. The above inspection methods have the following shortcomings:

[0004] 1. There are many outdoor overhead line towers, and the work intensity is high as one has to climb up the poles and towers one by one to check the porcelain bottles.

[0005] 2. Climbing poles and towers is very dangerous and may cause serious personal injury.

[0006] 3. If the porcelain bottle is damaged and not discovered and replaced in time, it will cause serious electrical accidents. Summary of the Invention

[0007] The technical problem to be solved by the present invention is to provide a porcelain bottle monitoring device that can determine the insulation performance of the porcelain bottle by ground observation.

[0011] When the insulation performance of the porcelain bottle deteriorates or flashover discharge or breakdown occurs, current flows through the crossbar, and the induction coil generates an induced voltage to provide electrical energy to the driving element. After receiving power, the driving element drives the flip cover to open, exposing the fluorescent lens.

[0012] Preferably, the driving element comprises an electromagnet, the electromagnet comprises an electromagnet core and an electromagnet coil wound around the electromagnet core, and the flip cover is provided with a permanent magnet;

[0013] in:

[0014] When the insulation performance of the porcelain bottle is normal, the flip cover is covered on the cylinder body by the magnetic attraction of the permanent magnet and the electromagnet;

[0016] Preferably, a spring is further provided in the barrel, and the spring is provided on the connecting shaft;

[0017] in:

[0018] When the insulation performance of the porcelain bottle is normal, the magnetic attraction force of the permanent magnet and the electromagnet is greater than the spring force of the spring;

[0019] When the insulation performance of the porcelain bottle decreases or flashover discharge or breakdown occurs, the spring force of the spring acts on the flip cover to open the flip cover.

[0027] See Figure 1-2 An embodiment of the present invention provides a porcelain bottle monitoring device, comprising a prompter and an induction coil, wherein the induction coil is wound around a crossbar of the porcelain bottle, and the prompter is fixed to the crossbar via a fixing element; the prompter comprises a housing, the housing comprising a barrel and a flip cover, a colored fluorescent lens and a driving element are disposed within the barrel, the flip cover is connected to the barrel via a connecting shaft, and the driving element is connected to the induction coil;

[0028] in:

[0029] When the insulation performance of the porcelain bottle is normal, the flip cover is covered on the cylinder body;

[0030] When the insulation performance of the porcelain bottle deteriorates or flashover discharge or breakdown occurs, current flows through the crossbar, and the induction coil generates an induced voltage to provide electrical energy to the driving element. After receiving power, the driving element drives the flip cover to open, exposing the fluorescent lens.

[0031] It should be noted that the driving element in this embodiment is not limited to a certain form, as long as it can drive the flip-up action after obtaining electrical energy, exposing the colored fluorescent lens for prompting, so that the staff can intuitively observe and judge the status of the porcelain bottle.

[0032] The device of this embodiment has the following advantages:

[0033] 1. Through the principle of electromechanical automation, it can accurately indicate that the porcelain bottle of the tower has been struck by lightning;

[0034] 2. Use induction electricity as the power source, without the need for batteries or other energy sources;

[0035] 3. Simple structure, easy installation and reusable;

[0036] 4. Use color to transmit signals, which is safe, reliable and low cost.

[0037] In some embodiments, the driving element includes an electromagnet, the electromagnet includes an electromagnet core and an electromagnet coil wound around the electromagnet core, and the flip cover is provided with a permanent magnet;

[0038] in:

[0039] When the insulation performance of the porcelain bottle is normal, the flip cover is covered on the cylinder body by the magnetic attraction of the permanent magnet and the electromagnet;

[0040] When the insulation performance of the porcelain bottle decreases or flashover discharge or breakdown occurs, the electromagnet is energized to generate a magnetic field, and the magnetic field of the electromagnet and the magnetic field of the permanent magnet cancel each other out, and the flip cover opens.

[0041] Specifically, when current flows through an electromagnet, it generates magnetism. The direction of its magnetic poles is opposite to that of the strong magnet, and the magnetic field strength of the electromagnet is greater than that of the permanent magnet. The magnetic field of the electromagnet cancels out the magnetic field of the strong magnet. When the induced voltage disappears, the magnetic field of the electromagnet disappears, and the magnetic field strength of the permanent magnet is restored.

[0042] In some embodiments, a spring is further provided in the barrel, and the spring is provided on the connecting shaft;

[0043] in:

[0044] When the insulation performance of the porcelain bottle is normal, the magnetic attraction force of the permanent magnet and the electromagnet is greater than the spring force of the spring;

[0045] When the insulation performance of the porcelain bottle decreases or flashover discharge or breakdown occurs, the magnetic attraction of the permanent magnet and the electromagnet disappears, and the spring force of the spring acts on the flip cover to open the flip cover.

[0046] In some embodiments, the driving element further includes a varistor, one end of the varistor is connected to one end of the induction coil, and the other end is connected to the electromagnet coil, and one end of the electromagnet core is connected to the other end of the induction coil.

[0047] Specifically, when a momentary induced high potential enters the power input terminal of the varistor and exceeds the breakdown voltage of the varistor, a voltage suppression action is generated, allowing the instantaneous rising current to flow through the varistor and the electromagnet coil. The electromagnet generates magnetism, with the magnetic pole direction opposite to that of the strong magnet. The magnetic field strength of the electromagnet is greater than that of the permanent magnet, and the magnetic field of the electromagnet cancels out the magnetic field of the strong magnet. When the induced voltage disappears, the magnetic field of the electromagnet disappears, and the magnetic field strength of the permanent magnet is restored.

[0048] In some embodiments, the fluorescent lens is a red fluorescent lens. The red color is brighter and easier to observe. Of course, it can also be other bright colors.

[0049] The above is a further detailed description of the present invention in conjunction with specific preferred embodiments, and the specific implementation of the present invention should not be considered to be limited to these descriptions. For those skilled in the art of the present invention, without departing from the concept of the present invention, several simple deductions or substitutions can be made, which should be considered to fall within the scope of protection of the present invention.
