Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a transformer with a good sealing structure. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change alternating current (AC) voltage. Its main components are a primary coil, a secondary coil, and an iron core. Transformers operate based on the law of electromagnetic induction. When AC current is applied to the primary coil of a transformer, an alternating magnetic field is generated in the iron core. This alternating magnetic field passes through the secondary coil, inducing an electromotive force (EMF) in the secondary coil according to the principle of electromagnetic induction. In substations of power systems, transformers distribute high-voltage electrical energy to distribution lines of different voltage levels, providing suitable power to different users and electrical equipment.

This utility model, through the combination of the limiting shell, sealing plate, movable block, spring, and connecting shell, enhances the protective performance of the transport pipe, preventing mechanical damage and corrosion, improving its sealing performance, and increasing the safety and reliability of the equipment. Simultaneously, the use of the protective structure and connecting block enhances the support for the oil conservator, effectively improving the stability of the equipment.

[0004] However, while this utility model can protect the transport pipe during use, it lacks a structure for timely oil leakage monitoring if the transport pipe is damaged and leaks oil. This makes it difficult for staff to perform timely maintenance, affecting the normal use of the transformer and failing to meet production needs. Therefore, a transformer with a good sealing structure is proposed to solve the problems mentioned above. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a transformer with a good sealing structure, which has the advantage of convenient oil leakage monitoring. It solves the problem that although existing transformers can protect the transport pipe, if the transport pipe is damaged and causes oil leakage, there is no structure to detect the oil leakage in time, which makes it difficult for staff to maintain the transformer in a timely manner and affects the normal use of the transformer.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a transformer with a good sealing structure, including a mounting base and a transformer body fixedly connected to the top of the mounting base, wherein an oil reservoir is provided on the top of the transformer body, and an oil leakage monitoring mechanism is provided between the oil reservoir and the transformer body.

[0007] The oil leakage monitoring mechanism includes an oil delivery pipe fixedly connected between the transformer body and the oil storage tank. A sealing protective cover is fixedly connected to the outside of the oil delivery pipe. An installation housing is fixedly connected to one side of the sealing protective cover. A liquid level sensor is fixedly connected inside the installation housing. A connecting pipe is fixedly connected between the installation housing and the sealing protective cover.

[0008] Furthermore, a sealing gasket is fixedly connected between the sealing protective cover and the oil pipeline, and the end of the connecting pipeline away from the mounting shell is located on the inner bottom wall of the sealing protective cover.

[0009] Furthermore, a level gauge is fixedly connected to one side of the oil reservoir, and a connecting pipe is fixedly connected between the level gauge and the oil reservoir. A level float is slidably connected inside the level gauge.

[0010] Furthermore, the liquid level gauge has a scale line on its front side, and an oil gauge breather plug extending into the top of the liquid level gauge is fixedly connected thereto.

[0011] Furthermore, an inflatable capsule is provided inside the oil storage pillow, and a breathing tube extending to the outside of the oil storage pillow is fixedly connected to the top of the inflatable capsule. A respirator is fixedly connected to the end of the breathing tube away from the inflatable capsule.

[0012] Furthermore, a vent pipe extending to the top of the inflatable capsule is fixedly connected to the top of the oil reservoir, and the outer surface of the inflatable capsule is in contact with the oil phase inside the oil reservoir.

[0013] Furthermore, an oil injection pipe is fixedly connected to the top of the oil reservoir and communicates with its interior, and a drain pipe is fixedly connected to the bottom of the oil reservoir on the side away from the oil injection pipe.

[0014] Furthermore, a support plate is fixedly connected to the bottom of the oil storage tank, and a fixing bolt is threadedly connected between the support plate and the upper surface of the transformer body.

[0015] Compared with the prior art, this utility model provides a transformer with a good sealing structure, which has the following beneficial effects:

[0016] 1. This transformer with a good sealing structure can protect the outer surface of the oil pipeline by setting a sealing protective cover. At the same time, by setting an installation shell and connecting pipe, it can prevent the oil leaking from the oil pipeline from dripping directly into the outside. This allows the oil to enter the installation shell through the connecting pipe. Furthermore, by setting a liquid level sensor, it can quickly react when oil is generated inside the installation shell, which can facilitate timely maintenance by the staff and improve the overall sealing performance.

[0017] 2. This transformer, with its excellent sealing structure, utilizes connecting pipes and a level gauge. Through the principle of communicating vessels, the oil level in the level gauge is made the same as the oil level in the oil reservoir. Furthermore, the addition of a level float allows staff to easily monitor the oil level in the oil reservoir, improving maintenance efficiency. This addresses the problem of existing transformers, which, while protecting the transport pipe, lack a mechanism for timely oil leakage detection in case of pipe damage, hindering timely maintenance and affecting the normal operation of the transformer.

[0023] Please see Figures 1 to 3This embodiment of a transformer with a good sealing structure includes a mounting base 1 and a transformer body 2 fixedly connected to the top of the mounting base 1. An oil reservoir 3 is provided on the top of the transformer body 2. An oil leakage monitoring mechanism is provided between the oil reservoir 3 and the transformer body 2. The oil leakage monitoring mechanism includes an oil delivery pipe 4 fixedly connected between the transformer body 2 and the oil reservoir 3. A sealing protective cover 5 is fixedly connected to the outside of the oil delivery pipe 4. An installation housing 6 is fixedly connected to one side of the sealing protective cover 5. A liquid level sensor 8 is fixedly connected inside the installation housing 6. A connecting pipe 7 is fixedly connected between the installation housing 6 and the sealing protective cover 5.

[0024] Specifically, a sealing gasket is fixedly connected between the sealing protective cover 5 and the oil pipeline 4, and the end of the connecting pipeline 7 away from the mounting shell 6 is located on the inner bottom wall of the sealing protective cover 5.

[0025] It should be noted that the liquid level sensor 8 is a GEMSCAP-300 capacitive liquid level sensor. An alarm is fixedly installed on the transformer body 2. The liquid level sensor 8 is connected to the alarm signal. By setting a sealing protective cover 5, the outer surface of the oil pipeline 4 can be protected. At the same time, by setting an installation shell 6 and a connecting pipe 7, the oil leaking from the oil pipeline 4 can be prevented from dripping directly into the outside. This allows the oil to enter the installation shell 6 through the connecting pipe 7. By setting a liquid level sensor 8, when oil is generated inside the installation shell 6, it can react quickly, which facilitates timely maintenance by the staff and improves the overall sealing performance.

[0026] Please see Figure 1 and Figure 2 In this embodiment, a level gauge 9 is fixedly connected to one side of the oil reservoir 3, and a connecting pipe 10 is fixedly connected between the level gauge 9 and the oil reservoir 3. A level float 11 is slidably connected inside the level gauge 9, and a scale line is provided on the front of the level gauge 9. An oil gauge breather plug 12 extending into the top of the level gauge 9 is fixedly connected.

[0027] Specifically, by setting up connecting pipe 10 and level gauge 9, the oil volume inside level gauge 9 is made the same as the oil volume inside oil reservoir 3 through the principle of communicating vessels. Furthermore, by setting up level float 11, it is convenient for staff to check the oil volume inside oil reservoir 3, thereby improving the maintenance efficiency of staff.

[0028] Please see Figure 1 and Figure 2In this embodiment, an inflatable capsule 13 is provided inside the oil storage pillow 3. A breathing tube 14 extending to the outside of the oil storage pillow 3 is fixedly connected to the top of the inflatable capsule 13. A respirator 15 is fixedly connected to the end of the breathing tube 14 away from the inflatable capsule 13. A vent pipe 16 extending to the top of the oil storage pillow 3 is fixedly connected to the top of the inflatable capsule 13. The outer surface of the inflatable capsule 13 is in contact with the oil inside the oil storage pillow 3. An oil injection pipe 17 communicating with the inside of the oil storage pillow 3 is fixedly connected to the top of the oil storage pillow 3. A drain pipe 18 is fixedly connected to the bottom of the oil storage pillow 3 on the side away from the oil injection pipe 17.

[0029] Please see Figure 1 In this embodiment, a support plate 19 is fixedly connected to the bottom of the oil storage pillow 3, and a fixing bolt is threaded between the support plate 19 and the upper surface of the transformer body 2. There are two support plates 19.

[0030] The working principle of the above embodiments is as follows:

[0031] First, the staff injects oil into the oil reservoir 3 through the oil injection pipe 17. At this time, due to the function of the breather 15, when the oil level inside the oil reservoir 3 changes, the air bladder 13 will inflate and deflate, thereby ensuring the balance of the internal and external pressure of the oil reservoir 3 and ensuring that the oil tank is always full of oil. At this time, the staff can judge the current oil level inside the oil reservoir 3 according to the position of the liquid level float 11. When oil is generated inside the housing 6, it can react quickly, and the staff can perform maintenance in time.

[0032] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods, and any method that achieves the desired beneficial effect can be implemented. Furthermore, all electrical components in this embodiment are electrically connected to the main controller and power supply. The main controller can be a conventional, known device such as a computer that performs control functions. Those skilled in the art can control the electrical components through simple programming, and the existing disclosed power connection technologies are common knowledge in the field. Therefore, this embodiment will not elaborate further on their specific structural composition and working principles.
