Description

Technical Field

[0001] This application relates to the field of power engineering equipment technology, and in particular to a transformer that is easy to install. Background Technology

[0002] Oil-immersed power transformers, as key equipment in power systems for voltage transformation, power transmission, and distribution, play an extremely important role in the power supply field. Relying on insulating oil as a cooling and insulating medium, they effectively ensure the normal operation and reliability of the transformer. During the operation of oil-immersed power transformers, accurately monitoring the oil level inside the transformer is crucial for ensuring its safe and stable operation. A suitable oil level ensures good cooling and insulation, preventing winding exposure due to low oil levels, which can lead to decreased insulation performance or even short circuits. Simultaneously, it prevents excessive pressure within the tank due to high oil levels, which could cause oil leaks or equipment damage.

[0003] A search revealed Chinese Patent Publication No. CN113707408B, which discloses a transformer that is easy to install. The transformer includes a mounting base and two mounting boxes. The mounting base has an internal mounting cavity. The top of the mounting base is fitted with the transformer housing. Sliding parts are fixedly connected to the bottom of both sides of the transformer housing. Sliding openings are provided on both sides of the top of the mounting base. The bottom of each sliding part is slidably connected within the sliding opening and extends into the mounting base. Sliding rods are slidably connected to both sides of the outer side of the mounting base, with the lower half of each sliding rod slidably connected within the mounting base. This invention, through the cooperation of sliding rods, mounting boxes, fixing openings, push plates, handles, and support springs, as well as the main mounting base, connecting parts, auxiliary mounting base, rotating shaft, rotating plate, clamps, sliding openings, and sliding grooves, can firmly fix the transformer housing to the mounting base and easily remove it from the mounting base, increasing the practicality of the device.

[0004] Regarding the aforementioned technologies, the inventors have discovered the following deficiencies: the oil level monitoring system of the aforementioned device is outdated in design, does not involve a quick oil circuit connection structure between the oil level gauge and the transformer body, still requires traditional hard connection and shutdown to drain the insulating oil during installation, and lacks intelligent monitoring methods such as pressure-sensing triggered light and color early warning and multi-color LED dynamic display. Oil level observation relies on manual labor and is greatly affected by ambient light. Utility Model Content

[0005] To address the problems mentioned in the background section, this application provides a transformer that is easy to install.

[0006] This application provides an easy-to-install transformer, which adopts the following technical solution: an easy-to-install transformer includes a transformer body, an oil tank bracket is fixedly installed on one side of the transformer body, and a quick-release oil level gauge assembly is provided on the top of the oil tank bracket;

[0007] A quick-release oil level gauge assembly includes an oil tank body fixedly installed on the top of an oil tank bracket, an oil supply pipe connecting the oil tank body and a transformer body, and a quick-release oil level metering component. The oil level metering component includes a lightweight disc detachably connected to the top of the oil tank body, a limiting post vertically penetrating the lightweight disc, a float fixed to the bottom of the limiting post and suspended inside the oil tank body, and a strobe lamp body threaded to the top of the limiting post. An annular seal is provided at the contact point between the limiting post and the lightweight disc.

[0008] Through the above scheme, the linkage design between the floating roof and the limit column accurately reflects changes in oil level, the threaded connection of the strobe light facilitates quick replacement, and the lightweight structure reduces the overall load pressure.

[0009] Optionally, the oil level metering assembly further includes an oil level gauge housing fixed above a lightweight disc. The side wall of the oil level gauge housing is provided with at least one light-transmitting hole, and light-transmitting grids are symmetrically arranged on the opposite side wall. The top of the oil level gauge housing is connected to a positioning ring with a positioning hole by a thread.

[0010] The above solution creates a multi-angle observation window by connecting the light-transmitting hole and the grille. The threaded connection of the positioning ring ensures the stability of the housing and provides a precise alignment reference for the strobe light.

[0011] Optionally, the bottom surface of the lightweight disc is integrated with a pressure sensing module, which is electrically connected to the strobe lamp body. When the floating disc reaches a preset height, it triggers a change in the light color of the strobe lamp body.

[0012] Through the above solution, pressure sensing and optical warning are linked to achieve intelligent identification of oil level thresholds. Color changes provide intuitive indication of abnormal conditions, enhancing the equipment's safety early warning capabilities.

[0013] Optionally, the light-transmitting hole is embedded with an optical refractive element to disperse the light emitted by the strobe lamp body into a visible light spot.

[0014] Through the above solution, the optical refractive element expands the coverage of the warning light, and can still clearly identify the light spot signal in complex lighting environments, thereby improving the reliability of remote monitoring.

[0015] Optionally, the floating roof is made of closed-cell foam material with a density less than that of the insulating oil in the tank. The floating roof has a mounting groove in the center that is coaxially connected to the limiting post. The floating roof and the connecting rod form a sliding pair, and the connecting rod is fixedly connected to the bottom of the lightweight disc.

[0016] Through the above scheme, the closed-cell foamed floating roof combines oil resistance and high buoyancy, and the sliding pair structure ensures vertical motion accuracy and avoids measurement errors caused by oil fluctuations.

[0017] Optionally, the inner wall of the positioning hole of the positioning ring is provided with a guide protrusion, and the side wall of the bottom of the strobe lamp body is provided with a corresponding spiral guide groove to form a screw-in quick positioning structure.

[0018] The above solution enables tool-free installation of strobe lights by combining the guide convex strip with the spiral groove. The screw-in structure balances positioning accuracy and ease of operation, and shortens maintenance time.

[0019] Optionally, the strobe lamp body includes multiple sets of independently controllable LED beads, with different oil levels corresponding to the activation of different color combinations of LED beads.

[0020] The above solution combines multi-color LED beads to form a graded warning system, which intuitively displays the oil level range through color coding, and supports multi-level status monitoring and emergency response.

[0021] In summary, this application includes the following beneficial technical effects:

[0022] 1. This utility model comprises an oil tank body, a lightweight disc, a limiting post, a float, and a strobe light body. Through the fixed connection between the float and the limiting post, and the through-type engagement between the limiting post and the lightweight disc, the float can move synchronously with the rise and fall of the insulating oil level within the oil tank, causing the limiting post to move synchronously. The strobe light body at the top of the limiting post is connected to the limiting post via threads. Combined with the pressure sensing module on the bottom of the lightweight disc, when the float reaches a preset height, the strobe light color changes. This achieves the effect of real-time oil level sensing via the float and visual feedback via the strobe light, enabling rapid early warning of abnormal oil levels.

[0023] 2. This utility model incorporates components such as an oil level gauge housing, a light-transmitting hole, a light-transmitting grid, a positioning ring, and optical refractive elements. The positioning ring and the spiral guide groove of the strobe lamp body form a screw-in quick-positioning structure, allowing the strobe lamp body to be quickly installed inside the oil level gauge housing. The optical refractive elements embedded in the light-transmitting hole disperse the strobe lamp light into visible spots. Combined with the symmetrically arranged light-transmitting grid, this allows light to pass through from multiple angles. Thus, through optimized optical structure and rapid positioning installation, this device achieves visualized monitoring of oil level status and facilitates multi-angle observation, improving the convenience and reliability of oil level observation.

[0029] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0030] This application discloses a transformer that is easy to install.

[0031] Please see Figure 1 A transformer that is easy to install includes a transformer body 1, an oil tank bracket 2 fixedly installed on one side of the transformer body 1, and a quick-release oil level gauge assembly 3 provided on the top of the oil tank bracket 2.

[0032] Please see Figures 2 to 4 The quick-release oil level gauge assembly 3 includes an oil tank body 301 fixedly installed on the top of the oil tank bracket 2, an oil supply pipe 302 for connecting the oil tank body 301 and the transformer body 1, and a quick-release oil level metering component. The oil level metering component includes a lightweight disc 308 detachably connected to the top of the oil tank body 301, a limiting post 312 vertically penetrating the lightweight disc 308, a float 311 fixed to the bottom of the limiting post 312 and suspended in the oil tank body 301, and a strobe lamp body 309 threadedly connected to the top of the limiting post 312. An annular seal is provided at the contact point between the limiting post 312 and the lightweight disc 308.

[0033] The floating roof 311 is made of closed-cell foam material, with a density less than that of the insulating oil inside the tank body 301. The floating roof 311 has a mounting groove at its center that is coaxially connected to the limiting post 312. The floating roof 311 and the connecting rod 310 form a sliding pair, and the connecting rod 310 is fixedly connected to the bottom of the lightweight disc 308.

[0034] The bottom surface of the lightweight disc 308 is integrated with a pressure sensing module, which is electrically connected to the strobe lamp body 309. When the floating disc 311 reaches a preset height, it triggers a change in the light color of the strobe lamp body 309.

[0035] The strobe light body 309 contains multiple independently controllable LED beads, and different oil levels activate different color combinations of LED beads.

[0036] The oil level metering assembly also includes an oil level gauge housing 303 fixed above a lightweight disc 308. The oil level gauge housing 303 has at least one light-transmitting hole 304 on its side wall and light-transmitting grids 307 symmetrically arranged on its opposite side wall. The top of the oil level gauge housing 303 is connected by a positioning ring 305 with a positioning hole 306 through a thread.

[0037] The light-transmitting hole 304 is embedded with an optical refractive element, which is used to disperse the light emitted by the strobe lamp body 309 to form a visible light spot.

[0038] The positioning ring 305 has a guide protrusion on the inner wall of the positioning hole 306, and the strobe lamp body 309 has a corresponding spiral guide groove on the side wall at the bottom, forming a screw-in quick positioning structure.

[0039] Further explanation is needed regarding the quick-release oil level gauge assembly 3. Its main function is to achieve real-time monitoring, abnormal early warning, and convenient maintenance of the oil level in the transformer body 1. Its core components work together to construct an intelligent monitoring system that integrates oil level sensing, signal feedback, and quick-release structure. The floating plate 311 is made of low-density closed-cell foam material and floats up and down with the rise and fall of the insulating oil level in the oil tank body 301. Through the fixed connection between the limiting post 312 and the floating plate 311, the change in oil level is converted into the vertical displacement of the limiting post 312. The pressure sensing module on the bottom surface of the lightweight disc 308 senses the position of the floating plate 311 in real time. When the oil level reaches the preset critical height, it triggers the color change of the strobe lamp body 309. The oil level status is displayed intuitively through multiple independently controlled LED beads in different color combinations.

[0040] The light-transmitting hole 304 and the light-transmitting grid 307 of the oil level gauge housing 303, together with the optical refraction element, disperse the light from the strobe lamp body 309 into visible light spots, enabling clear observation from multiple angles and avoiding the blind spots of traditional oil level gauges. The positioning ring 305 and the spiral guide groove of the strobe lamp body 309 form a screw-in quick-release structure. Combined with the detachable connection between the lightweight disc 308 and the oil tank body 301, the entire oil level metering component can be quickly disassembled and assembled, facilitating inspection and maintenance. The oil pipe 302 connects the oil tank body 301 and the transformer body 1, ensuring oil circulation. At the same time, the oil level monitoring function is independently integrated through modular design, which not only ensures the structural stability of the transformer body 1, but also improves the safety of equipment operation and maintenance efficiency through visual early warning and convenient maintenance design.

[0041] The implementation principle of an easy-to-install transformer according to an embodiment of this application is as follows:

[0042] First, real-time oil level sensing: The floating plate 311 is made of closed-cell foam material with a density less than that of insulating oil and is suspended in the insulating oil in the tank body 301. When the transformer body 1 is connected to the tank body 301 through the oil supply pipe 302, the rise and fall of the insulating oil level directly drives the floating plate 311 to float up and down synchronously. The mounting groove in the center of the floating plate 311 is fixedly connected to the limiting post 312, which converts the vertical displacement of the oil level into the linear movement of the limiting post 312.

[0043] Secondly, the critical state is triggered: the limit post 312 passes through the lightweight disc 308 and an annular seal is set at the contact point with it to ensure the sealing of the oil tank body 301. The pressure sensing module integrated on the bottom surface of the lightweight disc 308 monitors the position of the float 311 in real time. When the float 311 rises or falls with the oil level to the preset critical height, the pressure sensing module triggers the strobe lamp body 309 through an electrical signal, causing multiple sets of LED beads inside to change the light color combination according to the preset logic.

[0044] Next, the visual signal feedback: the light emitted by the strobe lamp body 309 passes through the light-transmitting hole 304 on the side wall of the oil level gauge housing 303 and is dispersed into a visible light spot by the embedded optical refraction element. The symmetrically arranged light-transmitting grid 307 further optimizes the light emission angle, so that maintenance personnel can clearly observe the light spot signal representing the oil level status from different directions, avoiding the blind spot problem of traditional oil level gauges.

[0045] Next, quick disassembly and maintenance: The positioning ring 305 is connected to the top of the oil level gauge housing 303 by threads. The guide ridge on the inner wall of its positioning hole 306 cooperates with the spiral guide groove at the bottom of the strobe lamp body 309 to form a screw-in quick positioning structure. When maintenance is required, the strobe lamp body 309 can be quickly disassembled by simply rotating it. Combined with the detachable connection design between the lightweight disc 308 and the oil tank body 301, the entire oil level metering component can be conveniently disassembled and maintained.

[0046] Finally, system integration and oil circulation: the oil tank bracket 2 is fixedly installed on one side of the transformer body 1, and the oil supply pipe 302 connects to the internal oil circuit of the transformer body 1 to ensure that the insulating oil flows freely between the two and maintains the liquid level balance. Through modular design, the oil level monitoring function is independently integrated into the top of the oil tank bracket 2. Under the premise of not affecting the structural stability of the transformer body 1, intelligent monitoring and abnormal warning of the oil level status are realized, thereby improving the safety of equipment operation.

[0047] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
