Description

Technical Field

[0001] This application relates to the technical field of partial discharge detection, and in particular to a portable switchgear partial discharge detection device. Background Technology

[0002] Electricity is essential to people's lives. While it plays a vital role, it also poses significant risks and requires control devices. Currently, high-voltage switchgear is commonly used for this purpose. As a crucial power distribution network device, high-voltage switchgear can experience insulation degradation over long-term operation, leading to reduced electrical insulation strength and potential malfunctions.

[0003] Partial discharge refers to the discharge or breakdown phenomenon within a localized area of ​​the insulating medium caused by uneven electric field distribution or excessively high local electric field strength. Partial discharge is a major cause of insulation degradation and is closely related to the deterioration of insulating materials and the breakdown process of insulators. It can reflect defects and faults in the internal insulation of equipment. Partial discharge detection equipment can detect the operating status and insulation level of switchgear to maintain the safety of high-voltage switchgear. Therefore, effective detection of partial discharge is of great significance for the safe and economical operation of power equipment.

[0004] Chinese patent application number CN202121173119.0 discloses a partial discharge detection device, including a housing and a detection device body. A support plate is movably mounted on one side of the housing's inner cavity, and a pad is fixedly mounted on one side of the support plate. A groove is formed on the top of the pad, and the detection device body is placed within the groove. T-shaped grooves are formed on both the top and bottom sides of the housing's inner cavity, and a long plate is movably mounted inside the T-shaped grooves. The support plate and the long plate are movably connected. This invention, by having T-shaped grooves on the top and bottom of the housing, allows the front side of the long plate to contact a baffle via rollers, and the rear side of the long plate to contact the inner wall of the T-shaped groove via a spring. When the baffle is opened, the pushing force on the long plate decreases, and the spring generates a reverse pushing force, pushing the long plate out of the T-shaped groove, thereby removing the support plate and pad from the housing. This facilitates maintenance of the detection device body by personnel, eliminating the need to put their hands inside the housing, making it more convenient to use.

[0005] The aforementioned technologies have the following drawbacks: the electronic components and sensors inside the partial discharge detection equipment are very sensitive to humidity. High humidity environments may cause component performance to decline and sensor accuracy to decrease, thereby affecting the overall performance of the equipment. It may even accelerate the corrosion of internal metal parts and the aging of plastic parts, thus reducing the overall lifespan of the equipment. Therefore, it is particularly important to monitor and control the internal humidity of the equipment in real time. Utility Model Content

[0024] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] This application discloses a portable switchgear partial discharge detection device. (Refer to...) Figures 1 to 5A portable switchgear partial discharge detection device includes a housing 1 and a detection device body 2. A mounting groove 11 is provided on one side of the housing 1. A drying box 3 and a cover plate 4 are installed in the mounting groove 11. The drying box 3 is filled with a moisture-absorbing material, such as silica gel, calcium chloride, or molecular sieve, to absorb and fix the moisture inside the housing 1, thereby maintaining a dry environment inside the housing 1. The cover plate 4 is hinged inside the housing 1. A detection component for detecting the humidity level inside the housing 1 is provided on the side of the cover plate 4 facing the inside of the housing 1. A sealing component for closing the mounting groove 11 is provided on the cover plate 4 and the housing 1.

[0026] In this way, by installing the drying box 3 and the detection components, the humidity level inside the chamber 1 is monitored in real time, and corresponding measures are taken to maintain a suitable humidity level. At the same time, the sealing components ensure the sealing of the mounting groove 11 to prevent external moisture from entering the chamber 1. With the combined effect of these measures, the humidity inside the partial discharge detection equipment is monitored and controlled in real time, which can effectively protect the detection equipment body 2 from the damage of the humid environment and avoid the humid environment from affecting the overall performance of the equipment and causing a decrease in the service life of the equipment.

[0027] Specifically, refer to Figure 1 and Figure 3 In one embodiment, the detection component includes two sockets 41 and a humidity card 42. The sockets 41 have openings, and the openings of the two sockets 41 are arranged opposite each other. The sockets 41 are fixed to the cover plate 4, and the humidity card 42 is inserted into the two opposite sockets 41. This design is simple, intuitive, and convenient, and can effectively monitor the humidity level inside the equipment housing 1. By properly selecting and using the humidity card 42, and by regularly inspecting and maintaining it, the stability and reliability of the equipment can be ensured, and its service life can be extended.

[0028] In another embodiment, refer to Figure 4 and Figure 5 The detection components include a humidity sensor 43 mounted on the cover plate 4, a buzzer 12 mounted on the housing 1, and a controller connected to both the buzzer 12 and the humidity sensor 43. The controller is configured to activate the buzzer 12 when the humidity value detected by the humidity sensor 43 exceeds a set value. This achieves automated monitoring and intelligent alarm of the humidity level inside the housing 1. This design not only improves the reliability and stability of the equipment but also reduces the difficulty and labor intensity for users, providing them with a more convenient and efficient monitoring experience.

[0029] Furthermore, referring to Figure 4 and Figure 5The sealing assembly includes a sealing strip 44 disposed on the cover plate 4, and a sealing groove 13 is provided on the housing 1 corresponding to the sealing strip 44; when the cover plate 4 is closed, the sealing strip 44 is interference-fitted into the sealing groove 13, and locking assemblies for locking the cover plate 4 and the housing 1 are provided on the cover plate 4 and the housing 1.

[0030] The sealing strip 44 is made of an elastic material, such as rubber, silicone, or polyurethane, which has good sealing performance and durability. The sealing strip 44 is set on the edge of the cover plate 4 to form a tight contact with the sealing groove 13 on the housing 1 when the cover plate 4 is closed, thereby preventing external moisture, dust, and other impurities from entering the housing 1 as much as possible. By introducing the design of the sealing strip 44, the sealing groove 13, and the locking assembly, a tight seal and secure locking between the cover plate 4 and the housing 1 are achieved.

[0031] Furthermore, referring to Figure 1 and Figure 2 The locking assembly includes a straight rod 5, a handle 51, and a locking block 52. One end of the straight rod 5 is fixed to the housing 1, and the other end of the straight rod 5 is hinged to one end of the handle 51. The locking block 52 is fixed to the hinged end of the handle 51 and the straight rod 5. A buckle 45 for the locking block 52 to be inserted is fixed to the cover plate 4.

[0032] When it is necessary to lock the cover 4, close the cover 4 and make it tightly contact the housing 1. Then, rotate the handle 51 to make the latch 52 gradually approach and engage with the buckle 45 on the cover 4. When the latch 52 is fully engaged with the buckle 45, the locking assembly will lock the cover 4 securely to the housing 1.

[0033] When it is necessary to unlock the cover 4, rotate the handle 51 in the opposite direction to gradually disengage the locking block 52 from the latch 45 on the cover 4. Once the locking block 52 is completely disengaged from the latch 45, the locking component unlocks, and the cover 4 can be easily opened. This design achieves convenient locking and unlocking between the cover 4 and the housing 1, which not only improves the reliability and stability of the equipment but also reduces the difficulty of operation for the user.

[0034] Furthermore, referring to Figures 1 to 5 The cover plate 4 is made of transparent material, which allows users to directly observe the internal working status and component layout of the equipment without opening it. This is crucial for timely detection of equipment failures, troubleshooting, and daily monitoring.

[0035] At the same time, refer to Figure 4 and Figure 5The housing 1 contains a mounting bracket 14, on which the drying box 3 can be detachably mounted. By installing the drying box 3, the humidity inside the equipment can be effectively reduced, preventing electrical faults or performance degradation caused by excessive humidity. At the same time, the detachable drying box 3 design also makes equipment maintenance simpler and more efficient.

[0036] Additionally, refer to Figure 4 and Figure 5 The drying box 3 has sliders 31 fixed to both sides, and the mounting frame 14 has grooves 141 that correspond to the sliders 31. The drying box 3 is connected to the mounting frame 14 by sliding engagement of the sliders 31 and the grooves 141. This plug-in installation method allows for easy replacement and cleaning of the drying box 3, ensuring the effective maintenance of a dry environment inside the equipment. This design also improves the reliability and stability of the equipment and extends its service life.

[0037] The implementation principle of a portable switchgear partial discharge detection device according to an embodiment of this application is as follows:

[0038] By installing the drying box 3 and the detection components, the humidity level inside the chamber 1 is monitored in real time, and corresponding measures are taken to maintain a suitable humidity level. At the same time, the sealing components ensure the sealing of the mounting groove 11 to prevent external moisture from entering the chamber 1. With the combined effect of these measures, the humidity inside the partial discharge detection equipment is monitored and controlled in real time, which can effectively protect the detection equipment body 2 from the damage of the humid environment and avoid the humid environment from affecting the overall performance of the equipment and causing a decrease in the service life of the equipment.
