Description

Technical Field

[0001] The invention relates to the technical field of protective devices for supporting instruments and equipment in power systems, and in particular to a protective device for an SF6 pressure gauge. Background Art

[0002] In the layout of existing substations or other power system supporting facilities, SF6 is usually used as the working medium in some circuit breakers and current transformers. Accordingly, SF6 pressure gauges are usually arranged on these devices to monitor the pressure value of SF6 in the corresponding equipment to understand the working status of the equipment. Depending on the actual working conditions, these SF6 pressure gauges will be arranged indoors or outdoors.

[0003] Among them, for SF6 pressure gauges arranged in outdoor environments, how to safely and reliably shield them from rain and snow so that the SF6 pressure gauges can maintain stable and reliable operation in harsh environments such as rainy and snowy weather is one of the technical demands that the industry pays more attention to.

[0004] At present, when the industry installs SF6 pressure gauges in outdoor environments, a rain cover is usually arranged in conjunction with it. The rain cover is buckled onto the outside of the SF6 pressure gauge to shield a certain degree of rain and snow, thereby providing appropriate structural protection for the SF6 pressure gauge. Generally, the rain cover is made of transparent plastic materials such as acrylic materials, so that the staff can read the displayed value of the SF6 pressure gauge from the outside of the rain cover.

[0005] However, although the existing rain cover can meet the basic needs of shielding the SF6 pressure gauge arranged outdoors from rain and snow, in its actual assembly application, because most conventional rain covers are made of acrylic materials, they are very prone to aging and damage when used in outdoor environments for a long time. In particular, acrylic materials will quickly turn yellow after aging, and the transparency will also deteriorate rapidly, resulting in the staff being unable to read the displayed value of the SF6 pressure gauge outside the rain cover. Therefore, in actual operation, in order to accurately read the displayed value of the SF6 pressure gauge, the staff often needs to remove the rain cover and then read and record the displayed value of the SF6 pressure gauge. This not only increases the labor intensity of the staff, but also reduces the inspection and data recording efficiency of the SF6 pressure gauge.

[0006] In view of this, how to optimize the component structure of the device that provides rain and snow protection for the outdoor SF6 pressure gauge so that the staff can read the displayed value of the SF6 pressure gauge more intuitively and efficiently, thereby reducing the labor intensity of the staff and improving the inspection efficiency of the SF6 pressure gauge is an important technical problem that technical personnel in this field currently need to solve. Summary of the invention

[0007] The object of the present invention is to provide an SF6 pressure gauge protection device, which enables workers to read the displayed value of the SF6 pressure gauge intuitively and efficiently, thereby effectively reducing the labor intensity of relevant workers and correspondingly improving the inspection efficiency of the SF6 pressure gauge.

[0008] In order to solve the above technical problems, the present invention provides an SF6 pressure gauge protection device, comprising a main shell having a cavity inside, and a top cover arranged on the top of the main shell, wherein the top cover is encapsulated above the cavity in the main shell, so that the top cover and the main shell are matched to form a protection cavity capable of accommodating the SF6 pressure gauge;

[0009] The bottom of the main shell has a mounting hole connected to the protection cavity and capable of allowing the SF6 pressure gauge to pass through, and the front end of the main shell has an observation hole connected to the protection cavity.

[0010] Preferably, the top cover includes at least one inclined top plate, the top outer wall of the top plate is a plane, and the lowest point of the outer wall of the top plate is located at the junction of the outer wall of the top plate and the outer wall of the main shell.

[0011] Preferably, the top cover comprises two top plates, which are symmetrically arranged in the horizontal direction, the top edge portions of the outer walls of the two top plates are tightly fitted, and the distance between the outer walls of the two top plates in the horizontal direction increases from top to bottom.

[0012] Preferably, the main housing includes two vertically arranged side panels and a back panel, the two side panels are parallel to each other and arranged symmetrically in the horizontal direction, and the back panel is embedded between the rear ends of the two side panels;

[0013] The top plate and the side plates are arranged in a one-to-one correspondence along the vertical direction, and the bottom end of the top plate is closely connected to the top end of the corresponding side plate;

[0014] The top end of the back plate abuts against the bottom wall of the top plate.

[0015] Preferably, the bottom end of the top plate protrudes from the outer wall of the side plate in the horizontal direction, and the rear end of the top plate protrudes from the outer wall of the back plate in the horizontal direction.

[0016] Preferably, at least one guide groove is recessed on the outer wall of the top plate, and the guide groove extends from the top end to the bottom end of the outer wall of the top plate.

[0017] Preferably, the outer wall of the top cover and the outer wall of the main shell are both coated with a waterproof paint layer.

[0018] Preferably, a positioning and installation component capable of fixedly installing an SF6 pressure gauge is provided in the protection cavity.

[0019] Preferably, the positioning and mounting assembly comprises a positioning plate fixedly arranged at the bottom of the main housing, and the positioning plate is penetrated by a plurality of threaded positioning holes;

[0020] The positioning and mounting assembly also includes a mounting screw that is threadably adapted to the threaded positioning hole in a one-to-one correspondence and can be threadably matched with the base of the SF6 pressure gauge.

[0021] Preferably, the main shell and the top cover are both made of insulating material.

[0022] Compared with the above-mentioned background technology, the SF6 pressure gauge protection device provided by the present invention, during its installation and operation, installs the SF6 pressure gauge in position inside the protection cavity, so as to utilize the alignment assembly of the top cover and the main shell to provide reliable structural protection for the SF6 pressure gauge in the protection cavity at the top and peripheral sides, effectively avoiding the direct impact and influence of rain, snow, wind, sand or other severe weather in the outdoor environment on the main structure of the SF6 pressure gauge, and avoiding the damage or functional failure of the main structure of the SF6 pressure gauge due to the influence of outdoor weather, thereby effectively ensuring the long-term stable operation of the SF6 pressure gauge in the outdoor environment. Correspondingly, an observation hole connected to the protection cavity is opened at the front end of the main shell, so that when the staff inspects the SF6 pressure gauges in various places in the outdoor environment, they can intuitively read the display data on the SF6 pressure gauge in the protection cavity through the observation hole and record it accordingly. Since the observation hole is an open hole structure without any obstructions or covers, the problem of the staff being unable to intuitively read the displayed value of the SF6 pressure gauge outside the protective cover due to aging and yellowing of the acrylic material protective cover covering the outside of the SF6 pressure gauge in the prior art will not occur, thereby greatly improving the data reading and inspection efficiency of the SF6 pressure gauge by the staff, and there is no need to remove the protective cover on the outside of the SF6 pressure gauge during the inspection process, which effectively reduces the labor intensity of the staff, and reduces the corresponding maintenance cost of the SF6 pressure gauge accordingly, and further improves the inspection and data reading efficiency.

In this way, by utilizing the flat extension structure of the top outer wall of the top plate itself, rainwater or snowfall falling on the top outer wall of the top plate can flow or move naturally downward along the top outer wall of the top plate under the action of its own weight until it reaches the lowest point of the top outer wall of the top plate, and moves out of the main structure range of the top plate through the junction of the top outer wall of the top plate and the outer wall of the main shell, after which the rainwater or snowfall can naturally move downward along the outer wall of the main shell and fall to the ground below, or can directly fall to the ground through the position where the outer edge of the top outer wall at the lowest point of the top plate is connected to the outer wall of the main shell. In this way, by utilizing the inclined structure of the top outer wall of the top plate, rain and snow falling on the top outer wall of the top plate can be naturally discharged, preventing rainwater and ice and snow from accumulating on the top of the top cover, thereby preventing the top cover structure from collapsing and the top cover and main shell from being damaged due to the accumulation of rainwater or ice and snow on the top of the top cover. This further improves the component structural strength of the SF6 pressure gauge protection device, improves its working condition tolerance in the outdoor environment, and effectively extends the service life of its overall components, thereby providing long-lasting and reliable structural protection for the SF6 pressure gauge in the protection cavity.

[0031] The core of the present invention is to provide an SF6 pressure gauge protection device, which enables workers to read the displayed value of the SF6 pressure gauge intuitively and efficiently, thereby effectively reducing the labor intensity of relevant workers and correspondingly improving the inspection efficiency of the SF6 pressure gauge.

[0036] Please refer to Figure 1 and Figure 2 .

[0037] In a specific embodiment, the SF6 pressure gauge protection device provided by the present invention includes a main shell having a cavity inside, and also includes a top cover arranged on the top of the main shell. The top cover is encapsulated above the cavity in the main shell so that the top cover and the main shell are matched to form a protection cavity capable of accommodating the SF6 pressure gauge.

[0038] During the specific installation and operation process, the SF6 pressure gauge is installed in the protection cavity so that the top cover and the main shell can be assembled in alignment to provide reliable structural protection for the SF6 pressure gauge on the top and sides of the periphery in the protection cavity, effectively avoiding the direct impact and influence of rain, snow, wind, sand or other severe weather in the outdoor environment on the main structure of the SF6 pressure gauge, and avoiding damage or functional failure of the main structure of the SF6 pressure gauge due to the influence of outdoor weather, thereby effectively ensuring the long-term stable operation of the SF6 pressure gauge in the outdoor environment.

[0039] The bottom of the main shell is provided with a mounting hole which is communicated with the protection cavity and through which the SF6 pressure gauge can pass, and the front end of the main shell is provided with an observation hole which is communicated with the protection cavity.

[0040] Correspondingly, an observation hole connected to the protection cavity is opened at the front end of the main shell, so that when the staff inspects the SF6 pressure gauges in various places in the outdoor environment, they can intuitively read the display data on the SF6 pressure gauge in the protection cavity through the observation hole and record it accordingly. Since the observation hole is an open hole structure without any obstructions or covers, the problem of the staff being unable to intuitively read the displayed value of the SF6 pressure gauge outside the protective cover due to aging and yellowing of the acrylic material protective cover covering the outside of the SF6 pressure gauge in the prior art will not occur, thereby greatly improving the data reading and inspection efficiency of the SF6 pressure gauge by the staff, and there is no need to remove the protective cover on the outside of the SF6 pressure gauge during the inspection process, which effectively reduces the labor intensity of the staff, and reduces the corresponding maintenance cost of the SF6 pressure gauge accordingly, and further improves the inspection and data reading efficiency.

[0041] It is not difficult to see that in practical applications, the observation hole 115 can be directly formed by the front edge portions of the two side plates 113 and the front edge portions of the top cover 12, that is, Figure 1 The structural state shown. This component structure arrangement can further simplify the component structure of the SF6 pressure gauge protection device, optimize the stress distribution of its main shell 11 and other structural parts, and significantly increase the effective observation range of the observation hole 115, and optimize the reading efficiency of the staff on the displayed value of the SF6 pressure gauge located in the protection cavity 111, so that the inspection efficiency of the staff on each SF6 pressure gauge in the outdoor environment can be correspondingly improved, and the labor intensity of the staff can also be correspondingly reduced.

[0042] Specifically, the top cover 12 includes at least one inclined top plate 121 , the top outer wall of the top plate 121 is a plane, and the lowest point of the outer wall of the top plate 121 is located at the junction of the outer wall of the top plate 121 and the outer wall of the main shell 11 .

[0043] In this way, by utilizing the flat extended structure of the top outer wall of the top plate 121 itself, rainwater or snow falling on the top outer wall of the top plate 121 can naturally flow or move downward along the top outer wall of the top plate 121 under the action of its own weight until it reaches the lowest point of the top outer wall of the top plate 121, and moves out of the main structure of the top plate 121 through the junction of the top outer wall of the top plate 121 and the outer wall of the main shell 11. After that, the rainwater or snow can naturally move downward along the outer wall of the main shell 11 and fall to the ground below, or it can directly fall to the ground through the position where the outer edge at the lowest point of the top outer wall of the top plate 121 connects with the outer wall of the main shell 11.

[0044] Correspondingly, by utilizing the inclined setting structure of the top outer wall of the top plate 121, rain and snow falling on the top outer wall of the top plate 121 can be naturally discharged, thereby preventing rainwater and ice and snow from accumulating on the top of the top cover 12, thereby preventing the top cover 12 structure from collapsing and the top cover 12 and the main shell 11 from being damaged due to the accumulated rainwater or ice and snow on the top of the top cover 12. This further improves the component structural strength of the SF6 pressure gauge protection device, improves its working condition tolerance in the outdoor environment, and effectively extends the service life of the overall component, thereby providing long-lasting and reliable structural protection for the SF6 pressure gauge in the protection cavity 111.

[0045] Generally, the main shell 11 and the top cover 12 are made of insulating materials. Specifically, the main shell 11 and the top cover 12 can be made of acrylic materials, or other engineering plastics after comprehensive consideration of actual working conditions and production costs. In principle, as long as the structural strength of the main shell 11 and the top cover 12 can be guaranteed and the corresponding insulation performance requirements and component structural strength requirements are met to match the actual application needs of the SF6 pressure gauge protection device, it can be used.

[0046] More specifically, the top cover 12 includes two top plates 121, which are arranged symmetrically in the horizontal direction, and the top edge portions of the outer walls of the two top plates 121 are tightly fitted, and the distance between the outer walls of the two top plates 121 in the horizontal direction increases from top to bottom. In this way, the two top plates 121 form a "human"-shaped tower top structure that is narrow at the top and wide at the bottom, so that not only can the top outer wall of each top plate 121 still have an inclined plane structure to ensure the diversion and discharge effect of rain and snow falling on the top outer wall of the top plate 121, but also the component structure stress distribution of the top cover 12 can be significantly optimized to avoid deformation or damage of the top cover 12 structure caused by local stress concentration, thereby further improving the structural strength and working condition tolerance of the top cover 12, and making the overall component structure of the SF6 pressure gauge protection device more stable, reliable and durable.

[0047] It is not difficult to understand that in specific applications, the main structure of the top cover 12 may include multiple top plates 121 to further optimize the rainwater and snow discharge capacity of the top cover 12 and avoid the accumulation of rainwater or ice and snow on the top of the top cover 12. Of course, considering the application requirements under most working conditions and the reasonable planning of component costs, the main structure of the top cover 12 is still preferably a structure type in which two top plates 121 are symmetrically arranged and tilted as shown in the figure.

[0048] More specifically, the main housing 11 includes two vertically arranged side panels 113 and a back panel 114 . The two side panels 113 are parallel to each other and arranged symmetrically in the horizontal direction. The back panel 114 is embedded between the rear ends of the two side panels 113 .

[0049] The top plate 121 and the side plates 113 are arranged one by one in a vertical direction, and the bottom end of the top plate 121 is closely connected to the top end of the corresponding side plate 113. The top end of the back plate 114 is in contact with the bottom wall of the top plate 121.

[0050] By utilizing the coordinated cooperation of the two side panels 113 and the back panel 114, the SF6 pressure gauge installed in the protection cavity 111 can be provided with sufficient shielding and structural protection on both sides and the rear, so as to prevent rain, snow, wind and sand from invading the main structure of the SF6 pressure gauge through the side and the rear, thereby further optimizing the structural protection effect of the SF6 pressure gauge protection device on the SF6 pressure gauge.

[0051] Considering the assembly and application requirements under most working conditions, the bottom of the side plate 113 and the back plate 114 is preferably a straight bottom edge structure. If there are special assembly or shielding requirements in actual operation, the bottom edge of the side plate 113 and the back plate 114 can also be designed as a single sharp angle structure or a sawtooth structure composed of multiple sharp angles, or other regular or irregular shapes. In principle, as long as it can meet the actual assembly and application requirements of the SF6 pressure gauge protection device and ensure the structural protection effect of the SF6 pressure gauge.

[0052] On this basis, the bottom end of the top plate 121 protrudes horizontally from the outer wall of the side plate 113, and the rear end of the top plate 121 protrudes horizontally from the outer wall of the back plate 114. In this way, the edge of the rear end of the top plate 121 can form a protruding eaves structure relative to the outer wall of the back plate 114, so that the rear end of the top plate 121 can be used to provide a certain shielding protection for the back plate 114, to prevent rain, ice crystals or snow particles falling from the top of the device from directly hitting the outer wall of the back plate 114, to avoid damage to the back plate 114 structure or structural vibration of the main shell 11 due to frequent structural impacts on the outer wall of the back plate 114, so as to further optimize the overall structural stability and assembly strength of the prime SF6 pressure gauge protection device, and make its structural protection effect on the SF6 pressure gauge more sufficient and reliable.

[0053] In addition, at least one guide groove 122 is recessed on the outer wall of the top plate 121, and the guide groove 122 extends from the top to the bottom of the outer wall of the top plate 121. Rainwater or melted ice and snow falling on the top outer wall of the top plate 121 can gradually flow into the guide groove 122, and gradually flow to the bottom of the guide groove 122 under the action of self-weight along the extension direction of the guide groove 122, and the bottom of the guide groove 122 is located at the bottom of the top outer wall of the top plate 121, so that the rainwater, ice water or snow water in the guide groove 122 can be directly discharged to the ground below through the bottom of the top outer wall of the top plate 121, or after flowing to the outer wall of the main shell 11, continue to flow downward along the outer wall of the main shell 11 and finally fall to the ground below. In this way, the guide groove 122 can be used to efficiently guide rainwater and ice and snow falling on the top of the top plate 121, so as to further improve the rain and snow discharge efficiency on the top of the top plate 121, and correspondingly further avoid the accumulation of rainwater or ice and snow on the top of the top cover 12, thereby making the overall component structure of the top cover 12 and even the SF6 pressure gauge protection device more stable and reliable, and having a better structural protection effect on the SF6 pressure gauge in the protection cavity 111.

[0054] It is not difficult to understand that, in practical applications, the number of guide grooves 122 on a single top plate 121 can be three or more as shown in the figure, and each guide groove 122 should be extended from top to bottom along the extension direction of the outer wall of the top plate 121. Of course, two adjacent guide grooves 122 can be arranged in parallel as shown in the figure, or in a non-parallel arrangement structure, or even in a cross arrangement that is interconnected, so as to optimize the collection and discharge efficiency of fluids such as rainwater and ice and snow. In principle, any method can be used as long as it can meet the practical application needs of the SF6 pressure gauge protection device.

[0055] On the other hand, the outer wall of the top cover 12 and the outer wall of the main shell 11 are coated with a waterproof paint layer. Although the top cover 12 and the main shell 11 are both manufactured and formed using insulating materials such as engineering plastics, there is still a certain risk of rain and snow erosion and aging during long-term assembly and operation in outdoor environments. Accordingly, waterproof paint is applied to the outer walls of the top cover 12 and the main shell 11 to form a waterproof paint protective layer, which can greatly improve the rain and snow environment tolerance of the top cover 12 and the main shell 11, so that the two can better adapt to the long-term outdoor assembly and layout environment, improve the overall working condition tolerance and service life of the SF6 pressure gauge protection device, and meet the long-term reliable structural protection of the SF6 pressure gauge.

[0056] In addition, a positioning and installation assembly capable of fixing and installing the SF6 pressure gauge is provided in the protection cavity 111. The positioning and installation assembly can provide sufficient and reliable structural support for the SF6 pressure gauge, and optimize the structural adaptation effect between the SF6 pressure gauge and the protection cavity 111 accordingly, so that the protection effect of the SF6 pressure gauge protection device on the SF6 pressure gauge is more stable and reliable.

[0057] Further, the positioning and installation assembly includes a positioning plate 13 fixedly arranged at the bottom of the main housing 11, and a plurality of threaded positioning holes 131 are penetrated on the positioning plate 13; the positioning and installation assembly also includes mounting screws that are threadedly adapted to the threaded positioning holes 131 one by one and can be threadedly matched with the SF6 pressure gauge base. The positioning plate 13 is usually arranged vertically at the bottom of the back plate 114 so as to fit and reliably connect with the rear end surface of the base of the SF6 pressure gauge. Of course, the positioning plate 13 can also be a horizontally arranged plate body, and can be flexibly arranged on the inner wall of the back plate 114 or the inner wall of the side plate 113, so that the SF6 pressure gauge base can be placed on the positioning plate 13 accordingly, and then combined with the reliable assembly of the mounting screws, the assembly strength between the positioning plate 13 and the SF6 pressure gauge base is higher, and the assembly structure is more solid and reliable. However, considering the assembly requirements and component adaptation effects under most working conditions, it is still appropriate to select the vertically arranged positioning plate 13 as shown in the figure.

[0058] In summary, it can be seen that during the installation and operation of the SF6 pressure gauge protection device provided in the present invention, the SF6 pressure gauge is installed in position inside the protection cavity, so that the top cover and the main shell are assembled in position to provide reliable structural protection for the SF6 pressure gauge in the protection cavity at the top and peripheral sides, effectively avoiding the direct impact and influence of rain, snow, wind, sand or other severe weather in the outdoor environment on the main structure of the SF6 pressure gauge, and avoiding damage or functional failure of the main structure of the SF6 pressure gauge due to the influence of outdoor weather, thereby effectively ensuring the long-term stable operation of the SF6 pressure gauge in the outdoor environment. Correspondingly, an observation hole connected to the protection cavity is opened at the front end of the main shell, so that when the staff inspects the SF6 pressure gauges in various places in the outdoor environment, they can intuitively read the display data on the SF6 pressure gauge in the protection cavity through the observation hole and record it accordingly. Since the observation hole is an open hole structure without any obstructions or covers, the problem of the staff being unable to intuitively read the displayed value of the SF6 pressure gauge outside the protective cover due to aging and yellowing of the acrylic material protective cover covering the outside of the SF6 pressure gauge in the prior art will not occur, thereby greatly improving the data reading and inspection efficiency of the SF6 pressure gauge by the staff, and there is no need to remove the protective cover on the outside of the SF6 pressure gauge during the inspection process, which effectively reduces the labor intensity of the staff, and reduces the corresponding maintenance cost of the SF6 pressure gauge accordingly, and further improves the inspection and data reading efficiency.
