Description

Technical Field

[0001] This utility model relates to the field of transformer technology, specifically to a transformer measurement and control box housing. Background Technology

[0002] In the field of large power transformers, users install signal collection and control boxes to measure and control the transformers. As user requirements continue to increase, the requirements for protection and isolation of different measurement and control signals are becoming increasingly stringent to ensure signal accuracy, reliability, and ease of switch operation. This necessitates new requirements for the structural characteristics of the control boxes.

[0003] According to a disclosed measurement and control device for a box-type transformer (Publication No.: CN215377124U), it includes: a transformer box and a measurement and control mechanism. The transformer box is equipped with a sealing mechanism, which includes a sealing roller shutter, a rotating shaft, and at least one set of support modules. One end of the sealing roller shutter is rolled up to the outside of the rotating shaft. The support modules are located on the side of the sealing roller shutter near the transformer box to support the horizontal rolling of the sealing roller shutter. A driving mechanism is located at the end of the sealing roller shutter near the rotating shaft. The driving mechanism includes a driving gear, a worm gear, a connecting shaft, a bevel gear set, and a crank handle. The driving gear is sleeved on the outside of the rotating shaft and meshes with the worm gear. A lifting mechanism is provided inside the transformer box, which includes at least one lifting assembly, a first support plate, and a second support plate erected in parallel. This utility model uses the driving mechanism to open the sealing roller shutter, exposing the transformer box. An insulated handle pushes the first support plate, which in turn drives the second support plate, causing the measurement and control mechanism to move upwards, facilitating maintenance and replacement.

[0004] In the aforementioned application, the sealing shutter is opened by a drive mechanism and the measurement and control mechanism is moved upward by a lifting mechanism, which achieves the effect of sealing and protecting the enclosure and facilitating the maintenance of the measurement and control mechanism. However, the internal heat dissipation of the device is poor, which can lead to damage to the operating components and cause the transformer to malfunction. Furthermore, it does not provide protection for important or easily damaged internal components. Therefore, we propose a transformer measurement and control box enclosure. Utility Model Content

[0005] To overcome the above-mentioned defects, the embodiments of this utility model provide a transformer control box housing, which solves the technical problem of a transformer control box housing in the prior art.

[0006] According to one aspect, at least one embodiment of the present invention provides a transformer control box housing, comprising: a box body, a rainproof cap fixedly connected to the top of the box body, a lifting ring fixedly connected to the top of the rainproof cap, a left screen plate and a right screen plate bolted to the side of the box body, housing mounting holes opened on the side of the left screen plate and the right screen plate, a grounding bolt bolted to the side of the box body, an outer door rotatably connected to the side of the box body, a sealing pad fixedly connected to the inner side of the outer door, a sealing layer fixedly connected to the side of the sealing pad, a lock provided on the side of the outer door, a handle fixedly connected to the side of the lock, a cable outlet hole opened at the bottom of the box body, a sealing cover bolted to the inner side of the box body, and a heat dissipation mechanism provided inside the box body; The heat dissipation mechanism includes a motor, the bottom of which is fixedly connected to the inner bottom surface of the housing. A gear is fixedly connected to the end of the motor output shaft. A support is fixedly connected to the inner side of the housing. A rotating shaft is rotatably connected to the inner side of the support. A gear is fixedly connected to one end of the rotating shaft. A fan blade is fixedly connected to the circumferential surface of the rotating shaft. A heat dissipation pipe is fixedly connected to the side of the housing.

[0007] For example, in at least one embodiment of the present invention, a transformer control box housing is provided, which further includes: a panel mounting bolt is bolted to the side of the enclosure, and the number of the panel mounting bolts is set to be several and symmetrical to each other along the vertical central axis of the enclosure, so as to realize the reliable fixing of the panel and the enclosure, avoid excessive force at a single point causing loosening of the connection, prevent the enclosure from deforming due to uneven force, and ensure that the panel is neatly positioned and tightly fitted after installation.

[0008] The side of the enclosure has mounting holes for display devices and control switches, providing dedicated and precise mounting positions for the display devices and control switches, ensuring that they can be securely embedded in the enclosure and preventing installation misalignment or loosening.

[0009] The number of heat dissipation vents is set to several and arranged in a linear array at the bottom of the rain cap. Together with the heat dissipation mechanism, they accelerate the discharge of hot air out of the box through these evenly distributed heat dissipation vents.

[0010] The fan blades are arranged in a circular array on the circumferential surface of the motor shaft, forming a uniform and stable airflow during rotation. This avoids uneven heat dissipation caused by weak local airflow, significantly improving the heat dissipation coverage and efficiency. The rotation radius of the fan blades is smaller than the inner side radius of the housing, which can prevent the fan blades from rubbing and colliding with the inner wall of the housing during rotation, ensuring safe operation. At the same time, sufficient space is reserved for airflow, allowing hot air to smoothly enter the housing and be discharged.

[0011] According to another aspect, at least one embodiment of the present invention also provides a transformer control box housing, comprising: a storage mechanism provided inside the housing, the storage mechanism including a storage box, the bottom of the storage box being fixedly connected to the inner side of the housing, a roller being rotatably connected to the inner bottom surface of the storage box, a wheel rod being fixedly connected to the side of the roller, a storage box being rotatably connected to the circumferential surface of the wheel rod, and a handle being fixedly connected to the side of the storage box.

[0012] For example, in at least one embodiment of the present invention, a transformer control box housing is provided, which further includes: a wheel groove is provided on the inner bottom surface of the storage box, the width of the wheel groove is equal to the width of the roller, which can accurately limit the roller, so that the roller always rolls along the wheel groove trajectory, and avoids deviation or jamming when the storage box is pulled out.

[0013] The rollers are arranged in a number that are symmetrical about each other along the vertical center axis of the roller rod. This avoids overloading of individual rollers, which could cause wear or damage, and extends the service life of the rollers. It also prevents tilting or jamming due to a shift in the center of gravity, ensuring smooth and stable movement.

[0014] The number of wheel rods is set to several, and they are symmetrical to each other along the vertical central axis of the storage box, so as to provide balanced and stable support for the storage box, prevent individual wheel rods from being overloaded and bending and deforming, and extend the service life of the wheel rods.

[0015] The inner side of the box is provided with heat dissipation vents. The number of heat dissipation vents is set to several and arranged in a linear array on the inner side of the box. They can form an efficient airflow circulation with the heat dissipation mechanism, increase the air exchange area between the inside and outside of the box, and accelerate the discharge of hot air to reduce the internal temperature.

[0016] The beneficial effects of this utility model are as follows: In this invention, the coordinated operation of components such as the motor shaft, fan blades, and base plate within the heat dissipation mechanism accelerates the expulsion of hot air from the enclosure through the rainproof cap's vents. This, combined with the introduction of cool air through the bottom cable outlet, creates convection, achieving efficient cooling. The dustproof mesh prevents dust intrusion, protecting internal components, while the linear array design of the vents ensures even heat distribution, preventing localized overheating. This three-dimensional heat dissipation network balances the air pressure inside and outside the enclosure, preventing condensation and ensuring stable operation of the monitoring and control equipment at suitable temperatures, thus extending the equipment's lifespan.

[0017] In this invention, through the coordinated operation of components such as rollers, wheel rods, and storage boxes within the storage mechanism, the storage box can specifically store important and easily damaged components, effectively preventing damage to these components from collisions or interference from debris. The storage box is connected to rollers via wheel rods, and with matching wheel grooves inside the storage box, it moves smoothly and is less prone to misalignment during operation. A side grip allows for quick access by the operator. Multiple symmetrically distributed wheel rods and rollers enhance the stability of the storage box's movement. The overall structure is simple and practical, optimizing the use of internal space for a more organized layout and improving the efficiency of component retrieval during maintenance.

[0027] like Figures 1-5As shown, it illustrates a transformer control box housing according to an embodiment of the present invention, including a housing 1, a rain cap 2 fixedly connected to the top of the housing 1, a lifting ring 3 fixedly connected to the top of the rain cap 2, a left screen plate 4 and a right screen plate 5 bolted to the side of the housing 1, housing mounting holes 6 opened on the side of the left screen plate 4 and the right screen plate 5, a grounding bolt 7 bolted to the side of the housing 1, an outer door 8 rotatably connected to the side of the housing 1, a sealing foot pad 9 fixedly connected to the inner side of the outer door 8, a sealing layer 10 fixedly connected to the side of the sealing foot pad 9, a lock 11 provided on the side of the outer door 8, a handle 12 fixedly connected to the side of the lock 11, a cable outlet hole 13 opened at the bottom of the housing 1, a sealing cover 14 bolted to the inner side of the housing 1, and a heat dissipation mechanism 15 provided inside the housing 1. The heat dissipation mechanism 15 includes a base plate 151, the top of which is fixedly connected to the inner top surface of the housing 1, a housing 152 is fixedly connected to the bottom of the base plate 151, a dustproof net 153 is fixedly connected to the bottom of the housing 152, a motor shaft 154 is fixedly connected to the top of the dustproof net 153, a fan blade 155 is fixedly connected to the circumferential surface of the motor shaft 154, and a heat dissipation vent 156 is provided at the bottom of the rain cap 2.

[0028] The side bolts of the enclosure 14 are connected to the screen mounting bolts 16. There are several screen mounting bolts 16, which are symmetrical about each other along the vertical central axis of the enclosure 14. This ensures that the screen is reliably fixed to the enclosure 14, avoids excessive force at a single point that could cause the connection to loosen, prevents the enclosure 14 from deforming due to uneven force, and ensures that the screen is neatly positioned and tightly fitted after installation.

[0029] The side of the enclosure 14 is provided with a display device embedding mounting hole 17 and a control switch embedding mounting hole 18, which provide dedicated and precise installation positioning for the display device and the control switch, ensuring that the two can be firmly embedded in the enclosure 14 and avoiding installation misalignment or loosening.

[0030] The number of heat dissipation vents 156 is set in a linear array at the bottom of the rain cap 2. Together with the heat dissipation mechanism 15, hot air is accelerated to be discharged outside the box through these evenly distributed heat dissipation vents 156.

[0031] The number of fan blades 155 is set to several and arranged in a circumferential array on the circumferential surface of the motor shaft 154. When rotating, they form a uniform and stable airflow, avoiding uneven heat dissipation caused by weak local wind force, and greatly improving the heat dissipation coverage and efficiency. The rotation radius of the fan blades 155 is smaller than the inner side radius of the housing 152, which can prevent the fan blades 155 from rubbing and colliding with the inner wall of the housing 152 when rotating, ensuring safe operation. At the same time, sufficient space is reserved for airflow, so that hot air can smoothly enter the housing 152 and be discharged.

[0032] This embodiment provides a transformer control box housing. Through the coordinated operation of components such as the motor shaft 154, fan blades 155, and base plate 151 within the heat dissipation mechanism 15, hot air inside the box is rapidly expelled through the heat dissipation vents 156 of the rainproof cap 2, achieving efficient cooling. The dustproof mesh 153 prevents dust from entering and protects internal components, while the linear array design of the heat dissipation vents 156 ensures even heat dissipation, preventing localized overheating. This forms a three-dimensional heat dissipation network, balancing the air pressure inside and outside the box to prevent condensation, ensuring stable operation of the control equipment at a suitable temperature, and extending the equipment's service life.

[0033] See in some examples Figures 1-5 The enclosure 1 serves as the core load-bearing structure, with a rain cap 2 fixed to the top for rain protection. A lifting ring 3 on the top of the rain cap 2 facilitates hoisting. The left and right screen panels 4 and 5 are bolted to the sides of the enclosure 1, with mounting holes 6 for overall fixation. A grounding bolt 7 ensures electrical safety. The outer door 8 on the side of the enclosure 1 can be rotated and opened. Sealing pads 9 and a sealing layer 10 on its inner side enhance sealing. A lock 11 and a handle 12 facilitate opening and closing and provide protection. A cable outlet 13 at the bottom of the enclosure 1 allows wiring to pass through. The internal enclosure 14 is fixed by screen mounting bolts 16, and has mounting holes 17 for a display device and 18 for a control switch. When the heat dissipation mechanism 15 is working, the base plate 151 fixes the housing 152 to the top surface inside the box 1. The dustproof net 153 at the bottom of the housing 152 blocks dust. The motor shaft 154 drives the fan blade 155 to rotate and generate an upward airflow. The hot air generated by the equipment inside the box rises and is discharged through the heat dissipation port 156 at the bottom of the rainproof cap 2. Fresh cold air enters from the outlet hole 13, forming continuous convection to achieve heat dissipation.

[0034] refer to Figures 1-5 In some embodiments, a transformer control box housing further includes a storage mechanism 19, which includes a storage box 191. The bottom of the storage box 191 is fixedly connected to the inner side of the box body 1. A roller 192 is rotatably connected to the inner bottom surface of the storage box 191. A wheel rod 193 is fixedly connected to the side of the roller 192. A storage box 194 is rotatably connected to the circumferential surface of the wheel rod 193. A handle 195 is fixedly connected to the side of the storage box 194.

[0035] The inner bottom surface of the storage box 191 is provided with a wheel groove 20. The width of the wheel groove 20 is equal to the width of the roller 192, which can precisely limit the roller 192 so that the roller 192 always rolls along the track of the wheel groove 20, avoiding deviation or jamming when the storage box 194 is pulled out.

[0036] The number of rollers 192 is set to be several, and they are symmetrical to each other along the vertical central axis of the wheel rod 193. This avoids the wear or damage of a single roller 192 due to overload, extends the service life of the roller 192, prevents tilting or jamming due to the shift of the center of gravity, and ensures smooth and stable movement.

[0037] The number of wheel rods 193 is set to be several and they are symmetrical to each other along the vertical central axis of the storage box 194, so as to provide balanced and stable support for the storage box 194, prevent individual wheel rods 193 from being overloaded and bending and deforming, and extend the service life of the wheel rods 193.

[0038] The inner side of the housing 1 is provided with heat dissipation vents. The number of heat dissipation vents is set to a certain number and is arranged in a linear array on the inner side of the housing 1. It can form an efficient airflow circulation with the heat dissipation mechanism 15, increase the air exchange area between the inside and outside of the housing, and accelerate the discharge of hot air to reduce the internal temperature.

[0039] In this embodiment, through the cooperation of components such as rollers 192, wheel rods 193, and storage boxes 194 inside the storage mechanism 19, the storage box 194 can specifically store important and easily damaged components, effectively preventing such components from being damaged by collisions or interference from debris. The storage box 194 is connected to the rollers 192 via the wheel rods 193, and with the matching wheel grooves 20 inside the storage box 191, it moves smoothly and is not prone to misalignment when pulled out. The side handle 195 facilitates quick access for operators. Multiple symmetrically distributed wheel rods 193 and rollers 192 enhance the stability of the storage box 194's movement. The overall structure is simple and practical, optimizing the use of space inside the box for a more organized layout, and improving the efficiency of component retrieval during maintenance.

[0040] In this embodiment, the storage box 191 in the storage mechanism 19 provides a stable support base for the storage box 194. The storage box 194 can specifically store important and easily damaged components to prevent them from being damaged. The wheel rods 193 are symmetrically distributed along the vertical central axis of the storage box 194, and work with several rollers 192 to distribute the weight. The width of the wheel groove 20 is adapted to the width of the roller 192, which can guide the roller 192 to move smoothly and prevent deviation. The handle 195 makes it easy for the operator to pull out the storage box 194. The overall structure makes the internal layout of the box more organized, which saves space and allows for quick access to components. The matching design of the wheel groove 20 and the roller 192 further improves the stability of the movement of the storage box 194 and ensures the safety of the internal components.

[0041] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
