Description

Technical Field

[0001] This utility model relates to the field of power equipment monitoring technology, specifically to a dustproof and waterproof installation structure for an outdoor GIS partial discharge sensor unit. Background Technology

[0002] Gas-insulated gas-insulated switchgear (GIS) is a critical piece of equipment in power systems, and its operational reliability directly affects grid security. Partial discharge detection, as one of the most sensitive and effective means of assessing the internal insulation condition of GIS, has been widely used. To achieve real-time monitoring and early warning of insulation degradation trends in GIS equipment, it is usually necessary to install ultra-high frequency or ultrasonic partial discharge sensing units at locations such as the GIS casing or basin insulators for extended periods.

[0003] Partial discharge detection is an important method for assessing the insulation status of GIS equipment. As a core detection component, the partial discharge sensor unit often needs to be installed on the outdoor GIS body. However, the outdoor environment is complex, and the sensor unit is exposed to wind, rain, and dust for a long time, which can easily lead to decreased measurement accuracy, signal drift, or even equipment damage due to water ingress and dust accumulation.

[0004] Existing installation structures often use simple protective covers, which have problems such as fixed internal space, poor applicability, poor heat dissipation, and difficulty in sealing out wires. Furthermore, it is difficult to observe the sensor's working status after installation.

[0005] Therefore, there is an urgent need to design a dustproof and waterproof installation structure for outdoor GIS partial discharge sensor units to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a dustproof and waterproof installation structure for outdoor GIS partial discharge sensor units, so as to solve the problems of poor protection performance, insufficient adaptability and inconvenience of observation in the prior art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A dustproof and waterproof installation structure for an outdoor GIS partial discharge sensor unit includes a base, a protective shell for accommodating the sensor unit structure is provided above the base, the protective shell is a hollow rectangular structure, a protective component is provided at one end, and an abutment component is provided at the end of the protective shell away from the protective component.

[0009] The base has a through slot at the corresponding position of the protective shell, the protective shell has an open structure on one side of the through slot, and a heat dissipation mounting bracket is provided on the base at the position of the through slot.

[0010] Furthermore, the abutment assembly includes multiple sleeves connected to the protective shell, with corresponding support rods inside the multiple sleeves, and spring coils provided at the intersection of the sleeves and the support rods inside the sleeves;

[0011] The support rod has an abutment plate at the end away from the sleeve, and the size of the abutment plate is smaller than the size of the protective shell.

[0012] Furthermore, the protective component includes an end cap connected to the protective shell, and a baffle is provided at one end of the end cap located on the protective shell. The baffle and the end cap are provided with a plurality of telescopic columns inside.

[0013] Furthermore, the end cap away from the baffle is provided with a transparent cover, and a circular hole is opened at the corresponding position of the end cap and the transparent cover.

[0014] Furthermore, the size of the baffle is the same as that of the abutment plate, and a through hole is provided inside the baffle.

[0015] Furthermore, a connector is provided at each of the four corners inside the end cap, and a connection hole is provided at the corresponding position of the protective shell and the connector.

[0016] Furthermore, the heat dissipation mounting bracket is also equipped with guide posts inside.

[0017] Furthermore, a connecting bracket is provided at each of the four corners of the bottom of the base.

[0018] In the above technical solution, the dustproof and waterproof installation structure for an outdoor GIS partial discharge sensor unit provided by this utility model has the following advantages:

[0019] Equipped with independent protective components, the end caps and baffles work together to provide a sealed protection. The enclosed structure of the overall shell effectively blocks outdoor rain and dust from entering, significantly improving the equipment's dustproof and waterproof rating, making it suitable for use in harsh outdoor environments. The elastic abutment component uses a spring telescopic structure to flexibly press and fix the sensing unit, effectively offsetting the impact of vibrations during GIS equipment operation, preventing sensor loosening and misalignment, and ensuring stable detection accuracy.

[0020] The base features a through-slot and a dedicated heat dissipation mounting bracket, breaking away from the traditional fully enclosed structure. This design ensures protection while allowing for internal air circulation and heat dissipation, solving the problem of sensor heat buildup and aging, and extending the equipment's lifespan. The overall structure is modularly designed for easy assembly and disassembly. The wire posts are neatly arranged, and the transparent cover allows for direct observation of the internal working conditions. The compact structure and high stability make it suitable for the long-term operation and maintenance needs of outdoor GIS equipment. Attached Figure Description

[0028] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0029] like Figure 1-5As shown in the figure, the present invention provides a dustproof and waterproof installation structure for an outdoor GIS partial discharge sensor unit, including a base 1. A connecting frame 2 is provided at each of the four corners of the bottom end of the base 1 for securing the entire device to a designated frame or foundation of the GIS equipment. A protective shell 3 is provided above the base 1 to accommodate the sensor unit structure. The protective shell 3 is a hollow rectangular structure with a protective component 4 at one end and an abutting component 5 at the other end of the protective shell 3 away from the protective component 4. The protective shell 3 adopts a hollow rectangular structure design, with a protective component 4 at one end for front sealing and sensor signal transmission, and an abutting component 5 at the other end of the protective shell 3 away from the protective component 4 for pressing the sensor unit from the rear.

[0030] The base 1 and the protective shell 3 are respectively provided with through grooves 7. The protective shell 3 is open on one side of the through groove 7. The base 1 is provided with a heat dissipation mounting bracket 8 at the position of the through groove 7. The heat dissipation mounting bracket 8 is also provided with guide posts 9 inside.

[0031] In this embodiment, to achieve bottom heat dissipation, a through slot 7 is provided at corresponding positions on the base 1 and the protective shell 3. The bottom of the protective shell 3 is open on one side of the through slot 7, allowing the bottom of the sensing unit to be directly exposed to the area of ​​the through slot 7. A heat dissipation mounting bracket 8 is fixedly installed on the base 1 at the through slot 7. The heat dissipation mounting bracket 8 serves as a bottom support for the sensing unit and also allows heat to be dissipated through airflow. A guide post 9 is also integrated inside the heat dissipation mounting bracket 8. The signal cable and power cable of the sensing unit can pass through the heat dissipation mounting bracket 8, be neatly arranged by the guide post 9, and then lead out from the side of the base 1.

[0032] The abutment component 5 includes multiple sleeves 53 connected to the protective shell 3. The sleeves 53 are provided with corresponding support rods 52 inside, and spring coils are provided at the intersection of the sleeves 53 and the support rods 52 inside the sleeves 53.

[0033] Among them, the end of the support rod 52 away from the sleeve 53 is provided with an abutment plate 51, the size of the abutment plate 51 is smaller than the size of the protective shell 3.

[0034] In this embodiment, each sleeve 53 is internally fitted with a telescopic support rod 52. A spring coil is installed within the cavity of the sleeve 53, between the bottom wall of the sleeve 53 and the insertion end of the support rod 52, to provide a forward elastic thrust. A rectangular abutment plate 51 is fixedly installed at the end of the support rod 52 away from the sleeve 53. The outer dimensions of the abutment plate 51 are slightly smaller than the inner cavity dimensions of the protective shell 3, allowing it to slide smoothly within the shell to press against sensing units of different thicknesses.

[0035] The protective component 4 includes an end cap 41 connected to the protective shell 3. A baffle 43 is provided at one end of the end cap 41 located in the protective shell 3. Multiple telescopic columns 46 are provided inside the baffle 43 and the end cap 41.

[0036] A transparent cover 42 is provided at the end of the end cap 41 away from the baffle 43. A circular hole is provided at the corresponding position of the end cap 41 and the transparent cover 42. In order not to block the transmission and reception of signals, the transparent cover 42 is embedded in the end face of the end cap 41 away from the baffle 43. A circular hole is provided at the center position of the end cap 41 corresponding to the transparent cover 42, so that the detection signal emitted by the sensing unit can pass through the transparent cover 42 without obstruction.

[0037] In this embodiment, the baffle 43 has the same size as the abutment plate 51, and the two are corresponding to each other, clamping the sensing unit in the middle. A through hole 45 is provided on the surface of the baffle 43 to expose the signal acquisition end of the sensing unit and align it with the outside. Between the baffle 43 and the inner wall of the end cover 41, a plurality of telescopic columns 46 are evenly distributed and connected, which can play a role in buffering and shock absorption. When the end cover 41 is locked, the telescopic columns 46 flexibly push the baffle 43 to fit tightly against the front end face of the sensing unit.

[0038] The baffle 43 has the same dimensions as the abutment plate 51. The baffle 43 has a through hole 45 inside, which is used to expose the detection surface of the sensor or allow the circuit to pass through.

[0039] Each of the four corners inside the end cap 41 is provided with a connector 44, and a connection hole 6 is provided at the corresponding position of the protective shell 3 and the connector 44.

[0040] In this embodiment, the specific connection method between the end cap 41 and the protective shell 3 is as follows: a connector 44 is fixed at each of the four corners inside the end cap 41, and a connection hole 6 is opened at the corresponding position on the shell end face of the protective shell 3. The connector 44 passes through the end cap 41 and locks with the connection hole 6 to realize the detachable connection of the components.

[0041] During installation, first fix the base 1 to the GIS equipment via the connecting bracket 2. Open the protective assembly 4, place the partial discharge sensor unit on the heat dissipation mounting bracket 8, and seal its cable out through the lead wire post 9. Then close the protective shell 3, align the connector 44 on the end cover 41 with the connection hole 6 and lock it. At this time, one end of the sensor unit abuts against the abutment plate 51, compressing the support rod 52 and the internal spring; the other end abuts against the baffle 43, compressing the telescopic column 46. Under the action of the elastic force on both sides, the sensor unit is firmly clamped in the center, adapting to different thickness tolerances. After the end cover 41 is locked, it forms a seal with the end face of the protective shell 3. Finally, install the transparent cover 42. The internal heat is transferred to the base 1 for dissipation through the heat dissipation mounting bracket 8, while external water and dust are blocked by the multi-layer sealing structure, achieving excellent outdoor protection performance.

[0042] Work steps:

[0043] During operation, the sensor unit structure is first placed inside the protective housing 3. The end cap 41 is then fixed to the protective housing 3 by tightening the connector 44 inside the end cap 41. During the installation of the end cap 41, the telescopic column 46 moves the baffle 43, positioning one end of the sensor unit structure. As the end cap 41 is tightened, the other end of the sensor unit structure contacts the abutment plate 51, pushing it to move. This causes the support rod 52 to slide inside the sleeve 53, simultaneously compressing the spring coil. The elastic deformation of the spring coil buffers and clamps the sensor unit structure. In this way, the combined action of the baffle 43 and the abutment plate 51 ensures a stable installation of the sensor unit structure, preventing it from loosening under the vibrations of outdoor GIS equipment operation.

[0044] In terms of protection, the combination of the base 1 and the protective shell 3, along with the hollow rectangular structure of the protective shell 3 itself, ensures that the sensing unit structure is within a closed space. The heat dissipation mounting bracket 8 located at the opening of the through slot 7 provides structural support and dissipates the heat generated by the sensing unit during operation. The transparent cover 42 and circular hole on the end cover 41 allow partial discharge detection signals to pass through or be used for observation without removing the end cover 41, while the end cover 41 as a whole serves as a dustproof and waterproof seal at the front end. The through hole 45 on the baffle 43 allows the sensing unit's cables or detection terminals to pass through, and the lead post 9 is used to organize the cables, ensuring neat wiring and preventing cable tangling that could cause seal failure.

[0045] When maintenance or replacement of the sensor unit is required, simply loosen the end cap 41. The telescopic column 46 will retract the baffle 43, releasing the front end restriction of the sensor unit. Simultaneously, under the rebound force of the spring coil, the abutment plate 51 will push the sensor unit a certain distance towards the opening, facilitating removal by the operator. After maintenance or replacement, reinstall the end cap 41 and lock it in place using the connector 44 and the connecting hole 6 on the protective shell 3 to restore the clamping, fixing, and sealing protection. The connecting brackets 2 at the four corners of the bottom of the base 1 are used to fix the entire installation structure to the GIS equipment body.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
