Description

Technical Field

[0001] This application belongs to the technical field of oil-immersed devices, specifically an explosion-proof device for an oil-immersed equipment riser seat with an explosion-proof membrane. Background Technology

[0002] An oil-immersed equipment riser is a component installed on equipment such as oil-immersed transformers or reactors, typically located on the top or side of the equipment. It is primarily used for installing high-voltage components such as bushings. By raising the high-voltage section of the equipment, it facilitates the installation and connection of components like bushings, and also increases the electrical insulation distance, ensuring the safety and reliability of the equipment during operation.

[0003] As disclosed in publication number CN222580917U, a high-voltage riser device suitable for oil-immersed transformers is provided. An auxiliary oil tank is installed on the outside of the main oil tank of the oil-immersed transformer. The side wall of the main oil tank has an oil passage hole that communicates with the main oil tank on the inside and with the auxiliary oil tank on the outside. The high-voltage bushing tail terminal is fixedly installed on the outer wall of the auxiliary oil tank via a connecting flange, and the inner end of the tail terminal is located inside the auxiliary oil tank. The cable connected to the inner end of the tail terminal passes through the oil passage into the main oil tank and connects to the transformer windings. This utility model's high-voltage riser, installed on the transformer side wall, is a box-shaped auxiliary oil tank. The high-voltage conductor terminal and the inner end of the high-voltage bushing are both connected to the outer wall of the auxiliary oil tank, with a certain distance between it and the outer wall of the main oil tank. The electrical distance between the auxiliary oil tank and the electrical components inside the main oil tank is also greater, thus this utility model has better safety performance.

[0004] However, in actual use, it was discovered that the insulating oil sprayed out from the riser due to heating within the device. This oil was then collected in an explosion-proof enclosure to prevent splashing. However, because the enclosure contains oil and potentially some gas, and the enclosure components are in a highly charged environment, and given that most storage areas contain metal parts, there is a risk of electrical sparks and potential explosions. Therefore, a protective structure is needed to eliminate electrical sparks and arcing in the oil-containing enclosure components. Utility Model Content

[0005] The purpose of this application is to provide an explosion-proof device for an oil-immersed equipment riser with an explosion-proof membrane, in order to solve the problem that the design structure mentioned above plays a protective role and eliminates electric sparks and arcs induced by the oil storage box components.

[0006] The technical solution adopted in this application is as follows: an explosion-proof device for an oil-immersed equipment riser with an explosion-proof membrane, wherein multiple support rods are fixedly connected to the bottom surface of the explosion-proof oil tank, a connecting socket is slidably inserted into one end of the support rod relative to the side surface of the explosion-proof oil tank, a ceramic support platform is fixedly connected to the bottom surface of the connecting socket, a metal base is fixedly connected to the bottom surface of the ceramic support platform, multiple metal floor plates are fixedly connected to the side surface of the metal base, a base rod is slidably inserted into the side surface of the metal floor, a grounding sleeve is slidably inserted into one end of the base rod relative to the side surface of the metal floor, a grounding wire is fixedly connected to one end of the grounding sleeve relative to the side surface of the base rod, a grounding base is fixedly connected to one end of the grounding wire relative to the side surface of the grounding sleeve, and a metal frame is fixedly connected to the side surface of the metal base.

[0007] By adopting the above technical solution, operators use the explosion-proof oil tank as the oil storage component. The supporting rod, connecting socket, and ceramic support platform are insulated components that support the oil. The metal base and metal frame connected to the base form an integral metal cage-like component. The metal floor, base rod, grounding sleeve, grounding wire, and grounding base form a grounding component. This, together with the cage-like component, forms a protective component similar to a Faraday cage. In the event of a large surrounding electrified environment or electric shock, the internal explosion-proof oil tank can maintain a stable potential, avoiding the possibility of an explosion inside the explosion-proof oil tank. Furthermore, the entire cage-like component also provides protection against impacts to the explosion-proof oil tank.

[0008] The explosion-proof oil tank, as the main component for storing oil, is generally made of metal and its interior can withstand high-pressure environments. The connection between the support rod and the connector socket serves two purposes: firstly, it provides positioning; secondly, the support rod, being made of metal, and the connector socket, made of ceramic, provide insulation. The ceramic support platform, also made of ceramic, serves a load-bearing function without hindering the formation of the entire Faraday cage-like assembly.

[0009] The metal base, made of metal, forms a cage-like structure with the metal frame, providing protection while allowing pipes to pass through due to its larger spacing. The metal floor, serving as the connecting grounding component, features a sliding base plug that, together with the grounding bushing, forms the on-site control switch for the grounding device. The grounding bushing's other end connects to the grounding base via a grounding wire, further enhancing grounding efficiency.

[0010] The aforementioned components not only provide electromagnetic protection similar to a Faraday cage, but also serve as direct protection against impacts.

[0011] In a preferred embodiment, a base is fixedly connected to the upper surface of the metal frame, and a flip cover is rotatably inserted into the side surface of the base.

[0012] By adopting the above technical solution, the base is used to connect the flip cover, forming a flip-top cover component. Before the cover flips, it is convenient for operators to maintain the explosion-proof oil tank. After flipping, it is combined with the metal frame to form a complete iron cage, thus achieving specific protection for the explosion-proof oil tank.

[0013] In a preferred embodiment, the side surface of the flip cover is provided with a connecting opening, and a bundle tube is fixedly inserted into the side surface of the explosion-proof oil tank.

[0014] By employing the above technical solution, the connecting opening is used to insert into the protruding block on the metal frame, thus securing the flip-top after it is turned upside down. The bundled tube is used to guide the oil into the explosion-proof oil tank.

[0015] In a preferred embodiment, a discharge pipe is fixedly inserted into one end of the explosion-proof oil tank relative to the side surface of the explosion-proof oil tank, and a shut-off valve is provided on the side surface of the discharge pipe.

[0016] By adopting the above technical solution, when the internal pressure of the explosion-proof oil tank is too high, the pressure is discharged outward using a drain pipe, and then the shut-off valve is used to control the opening and closing of the drain pipe, thereby achieving reasonable control of the pressure inside the explosion-proof oil tank.

[0017] In a preferred embodiment, a limiting plug is inserted into the side surface of the connector.

[0018] By adopting the above technical solution, the connection between the support rod and the connecting socket is fixed by using the limiting bolt, thus preventing the connection of the explosion-proof oil tank from becoming loose.

[0019] In a preferred embodiment, the bundle tube is connected to a plurality of connecting tubes on one end side surface opposite to the explosion-proof oil tank.

[0020] By adopting the above technical solution, the oil is discharged through the connecting pipe and then collected and introduced into the explosion-proof oil tank through the bundle pipe.

[0021] In a preferred embodiment, the connecting tube has an opening on one end surface opposite the bundle tube.

[0022] By adopting the above technical solution, the opening is used as a through hole to facilitate the flow of oil into the tank.

[0023] In a preferred embodiment, an oil-immersed transformer is fixedly inserted into one end of the connecting tube relative to the bundle tube.

[0024] By adopting the above technical solution, the oil-immersed transformer, as the main body of the transformer, reduces the arc sparks generated by the dry air inside, and avoids the device risk caused by current breakdown.

[0025] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0026] In this application, the explosion-proof oil tank, as the main component for storing oil, is generally made of metal and its interior can withstand high-pressure environments. The connection between the support rod and the connector socket serves two purposes: firstly, it provides positioning; secondly, the support rod, being made of metal, and the connector socket, being made of ceramic, provide insulation. Furthermore, the ceramic support platform, also made of ceramic, serves a load-bearing function without hindering the formation of the entire Faraday cage-like assembly.

[0027] The metal base, made of metal, forms a cage-like structure with the metal frame, providing protection while allowing pipes to pass through due to its larger spacing. The metal floor, serving as the connecting grounding component, features a sliding base plug that, together with the grounding bushing, forms the on-site control switch for the grounding device. The grounding bushing's other end connects to the grounding base via a grounding wire, further enhancing grounding efficiency.

[0028] The aforementioned components not only provide electromagnetic protection similar to a Faraday cage, but also serve as direct protection against impacts. Attached Figure Description

A grounding base 10 is fixedly connected to one end of each grounding wire 9 relative to the side surface of the grounding sleeve 8. A metal frame 11 is fixedly connected to the side surface of the metal base 5.

[0037] The operator uses the explosion-proof oil tank 1 as the oil storage component. The supporting rod 2, connecting socket 3, and ceramic support platform 4 are insulating components that support the oil. The metal base 5 and metal frame 11 connected to the base form an integral metal cage-like component. The metal floor 6, base rod 7, grounding sleeve 8, grounding wire 9, and grounding base 10 form a grounding component. This component works with the cage-like component to form a protective component similar to a Faraday cage. In the event of a large surrounding electrified environment or electric shock, the explosion-proof oil tank 1 can still maintain a stable potential, avoiding the possibility of an explosion inside the explosion-proof oil tank 1. The entire cage-like component also provides protection against impacts to the explosion-proof oil tank 1.

[0038] The explosion-proof oil tank 1, as the main component for storing oil, is generally made of metal and its interior can withstand high-pressure environments. The connection between the support rod 2 and the connecting socket 3 serves two purposes: firstly, it provides positioning; secondly, the support rod 2, being made of metal, and the connecting socket 3, being made of ceramic, provide insulation. The ceramic support platform 4, also made of ceramic, serves a load-bearing function without hindering the formation of the entire Faraday cage-like assembly.

[0039] The metal base 5, made of metal, forms a cage-like structure together with the metal frame 11, providing protection while also facilitating pipe passage due to its larger spacing.

[0043] A discharge pipe 16 is fixedly inserted into one end of the explosion-proof oil tank 1, and a shut-off valve 17 is provided on the side surface of the discharge pipe 16. When the internal pressure of the explosion-proof oil tank 1 is too high, the discharge pipe 16 is used to discharge the oil, and then the shut-off valve 17 is used to control the opening and closing of the discharge pipe 16, thereby achieving reasonable control of the internal pressure of the explosion-proof oil tank 1.

[0044] A limiting plug 18 is inserted into the side surface of the connector 3. The limiting plug 18 is used to fix the connection between the support rod 2 and the connector 3, preventing the connection of the explosion-proof oil tank 1 from becoming loose.

[0045] Multiple connecting pipes 19 are connected to one end of the bundled pipe 15 relative to the explosion-proof oil tank 1. The oil is discharged through the connecting pipes 19 and then bundled and concentrated into the explosion-proof oil tank 1 through the bundled pipe 15.

[0046] An opening 20 is connected to one end of the connecting pipe 19 relative to the bundle pipe 15. The opening 20 serves as a through hole to facilitate the flow of oil into the box.

[0047] An oil-immersed transformer 21 is fixedly inserted into one end of the connecting pipe 19 relative to the bundle pipe 15. The oil-immersed transformer 21 serves as the main body of the transformer. The oil immersion method reduces the arcing sparks generated by the dry air inside, thus avoiding the device risk caused by current breakdown.

The supporting rod 2, connecting socket 3, and ceramic support platform 4 are insulated components, which serve as the supporting components. The metal base 5 and metal frame 11 connected to the bottom of the supporting rod 4 form an integral metal cage-like component. The metal floor 6, base rod 7, grounding sleeve 8, grounding wire 9, and grounding base 10 form a grounding component. This component works with the cage-like component to form a protective component similar to a Faraday cage. Under conditions such as a large surrounding electrified environment or electric shock, the explosion-proof oil tank 1 inside can still maintain a stable potential, avoiding the possibility of an explosion inside the explosion-proof oil tank 1. The entire cage-like component also plays a protective role, preventing the explosion-proof oil tank 1 from being bumped or knocked.
