Description

A transformer housing corrosion protection device Technical Field

[0001] This utility model relates to the field of transformers, and in particular to a transformer housing anti-corrosion treatment device. Background Technology

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization. Transformers are basic equipment for power transmission and distribution and are widely used in industry, agriculture, transportation, urban communities, and other fields.

[0003] Chinese Patent Publication No. CN205230715U discloses a novel transformer, which includes a transformer shell, a transformer body, and a heat dissipation section. The transformer body and the heat dissipation section are both mounted on the transformer shell. The heat dissipation section includes a heat-absorbing section, a heat-conducting pipe, and heat sinks. The heat-absorbing section is close to the transformer body. However, existing devices have some shortcomings. The existing transformer body is generally directly attached to the shell. In areas with high humidity, moisture can penetrate along the shell into the interior of the shell, causing the air inside the transformer to be humid. If the humidity is too high, it can easily cause corrosion inside the transformer. Therefore, we propose a transformer shell anti-corrosion treatment device to solve the above problems. Summary of the Invention

[0004] The purpose of this invention is to provide a transformer housing anti-corrosion treatment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A transformer housing corrosion protection device includes a protective housing, with multiple heat dissipation fins installed on the outer surface of the protective housing, a support assembly installed on the bottom surface of the protective housing, a transformer body installed inside the protective housing, and an installation assembly installed on the back of the protective housing. The installation assembly contains an exhaust assembly, a detection controller, and an anti-corrosion assembly.

[0007] In a further embodiment, the mounting assembly includes a mounting frame located on the back of the protective housing, a fixing clip installed inside the mounting frame, and a protective plate and a protective door respectively installed on the back of the mounting frame.

[0008] In a further embodiment, the exhaust assembly includes a vacuum pump located inside the mounting frame. The input end of the vacuum pump is connected to a first automatic control valve via a connecting pipe. The other end of the first automatic control valve penetrates the protective housing and extends into the interior of the protective housing.

[0009] In a further embodiment, the corrosion protection component includes two high-pressure storage cylinders, both of which are located inside the mounting frame. The output ends of the two high-pressure storage cylinders are connected to a second automatic control valve via a connecting pipe. The other end of the second automatic control valve penetrates the protective housing and extends into the interior of the protective housing.

[0010] In a further embodiment, a detection controller is installed inside the mounting frame. The rear end of the detection controller penetrates the protective housing and extends into the interior of the protective housing. The detection controller is electrically connected to the first automatic control valve and the second automatic control valve respectively via wires.

[0011] In a further embodiment, the support assembly includes two fixing plates, both of which are located on the bottom surface of the protective shell, and both fixing plates have multiple fixing holes on their bottom surfaces.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model discloses a transformer casing anti-corrosion treatment device. By installing an exhaust component and an anti-corrosion component in the mounting assembly on the back of the protective casing, the air inside the casing can be extracted, and inert gas from a high-pressure storage gas cylinder can be introduced into the protective casing. This reduces the oxygen concentration inside the protective casing, and the inert gas slows down the corrosion process of the device. Regular maintenance and inspection of the protective casing can promptly detect and treat corrosion phenomena on the casing. Therefore, this device effectively solves the problem that existing devices are prone to causing corrosion inside transformers. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4. In this utility model, a transformer housing anti-corrosion treatment device includes a protective housing 1. Multiple heat dissipation fins 6 are installed on the outer surface of the protective housing 1. A support assembly 2 is installed on the bottom surface of the protective housing 1. A transformer body 19 is installed inside the protective housing 1. An installation assembly 3 is installed on the back of the protective housing 1. An exhaust assembly 4, a detection controller 8, and an anti-corrosion assembly 5 are respectively installed inside the installation assembly 3 on the back of the protective housing 1. By installing the exhaust assembly 4 and the anti-corrosion assembly 5 in the installation assembly 3 on the back of the protective housing 1, the air inside the housing can be extracted, and the inert gas in the high-pressure storage gas cylinder 16 can be filled into the protective housing 1, thereby reducing the oxygen concentration inside the protective housing 1 and slowing down the corrosion process of the device through the inert gas.

[0021] The mounting assembly 3 includes a mounting frame 10 located on the back of the protective housing 1. A fixing clip 17 is installed inside the mounting frame 10. A protective plate 11 and a protective door 12 are installed on the back of the mounting frame 10. The high-pressure storage gas cylinder 16 inside the mounting frame 10 can be easily replaced through the protective door 12. The high-pressure storage gas cylinder 16 can be clamped through the fixing clip 17 to ensure its stability.

[0022] The exhaust assembly 4 includes a vacuum pump 18, which is located inside the mounting frame 10. The input end of the vacuum pump 18 is connected to a first automatic control valve 13 via a connecting pipe 15. The other end of the first automatic control valve 13 passes through the protective housing 1 and extends into the interior of the protective housing 1. The output end of the vacuum pump 18 is located on the back of the mounting frame 10 and can exhaust gas. The vacuum pump 18 is an instrument that uses a motor-driven mechanical device to create negative pressure, thereby drawing in and expelling gas. It is commonly used in fields such as gas sampling and vacuum adsorption.

[0023] The corrosion protection component 5 includes two high-pressure storage cylinders 16, both of which are located inside the mounting frame 10. The output ends of the two high-pressure storage cylinders 16 are connected to a second automatic control valve 14 via a connecting pipe 15. The other end of the second automatic control valve 14 passes through the protective housing 1 and extends into the interior of the protective housing 1. The high-pressure storage cylinder 16 is one of the most traditional and common methods for storing nitrogen.

[0024] The mounting frame 10 houses a detection controller 8. The rear end of the detection controller 8 penetrates the protective housing 1 and extends into the interior of the protective housing 1. The detection controller 8 is electrically connected to the first automatic control valve 13 and the second automatic control valve 14 via wires. The detection controller 8 is a device specifically designed for detecting and controlling the concentration of inert gas in the environment. It can control the activation of the two automatic control valves based on the detected inert gas concentration data. The automatic control valve is a device that can automatically control gas flow and pressure. It is widely used in various industrial and scientific research fields. Its main functions include flow control and pressure regulation. It can accurately measure and control gas flow under high pressure.

[0025] The support assembly 2 includes two fixing plates 7, both of which are located on the bottom surface of the protective shell 1. The bottom surface of each fixing plate 7 is provided with multiple fixing holes 9, which facilitate the installation of the device.

[0026] The working principle of this utility model is as follows:

[0027] When using this transformer casing corrosion protection equipment, the operator first installs the device in a suitable position using the support assembly 2 and installs the components. Then, the detection controller 8 activates the exhaust assembly 4 to extract oxygen from the protective casing 1, and simultaneously activates the corrosion protection assembly 5 to fill the protective casing 1 with inert gas from the two high-pressure storage cylinders 16. The detection controller 8 then monitors the concentration of inert gas within the protective casing 1 and controls the exhaust assembly 4 and corrosion protection assembly 5 to alternately activate, thus maintaining the concentration of inert gas within the protective casing 1. Finally, after the device has been used for a period of time, the operator replaces or repairs the two high-pressure storage cylinders 16 and inspects and treats the corrosion within the protective casing 1.
