Description

Technical Field

[0001] This utility model relates to the field of voltage transformer technology, and more specifically, to the housing of a single-phase outdoor voltage transformer. Background Technology

[0002] A voltage transformer, abbreviated as PT, is used to transform the voltage on a line. It is used to protect valuable equipment, motors and transformers in the line when a fault occurs. According to the installation location, it can be divided into indoor type and outdoor type, and according to the number of phases, it can be divided into single-phase type and three-phase type.

[0003] A search revealed that Chinese patent CN213583322U discloses a housing for a single-phase outdoor voltage transformer. This structure simplifies the installation and removal of the housing on the mounting plate, saving people time and effort.

[0004] However, in actual use, when the voltage transformer housing is installed outdoors, it is easily affected by falling objects from heights or rain and snow due to the lack of protective structure, which affects the service life of the voltage transformer housing. In view of this, this utility model proposes a single-phase outdoor voltage transformer housing. Utility Model Content

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides a housing for a single-phase outdoor voltage transformer to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a single-phase outdoor voltage transformer housing, comprising a voltage transformer housing body, wherein two insulating bottles are installed on the voltage transformer housing body.

[0007] To protect the top of the voltage transformer housing, preferably, a protective structure is provided at the top of the voltage transformer housing. This protective structure includes two support blocks, each fixedly installed on the outer wall of the voltage transformer housing. Each support block has a screw at its top, and an adjusting block is located outside the screw. Locking nuts are located at the top and bottom of the adjusting block, which is slidably connected to the screw. The locking nuts are installed outside the screw and threadedly connected to it. One end of the adjusting block has an L-shaped sleeve, and a sleeve rod is slidably installed inside the L-shaped sleeve. A protective plate is installed at the top of both sleeve rods. A movable block is located at the bottom of the sleeve rod inside the L-shaped sleeve, and a buffer spring is located at the bottom of the movable block. The outer wall of the movable block is slidably connected to the inner wall of the L-shaped sleeve, and both ends of the buffer spring are fixedly connected to the movable block and the bottom of the inner cavity of the L-shaped sleeve, respectively.

[0008] In order to dissipate heat from the housing of the voltage transformer, preferably, ventilation openings are provided on both sides of the outer wall of the housing of the voltage transformer, a dustproof net is embedded inside the ventilation opening, and multiple louvers are movably installed inside the ventilation opening on one side of the dustproof net.

[0009] To facilitate the installation of the voltage transformer housing, preferably, a mounting plate is provided at the bottom of the voltage transformer housing, and the surface of the mounting plate has several threaded holes, each of which is threaded with a bolt.

[0010] The technical effects and advantages of this utility model are as follows:

[0011] 1. By setting up a protective structure, the adjusting block slides up and down outside the screw to adjust the height of the protective plate. The adjusting block is then fixed by locking the nut. The protective plate can protect the voltage transformer housing. In the event of a falling object, the elasticity of the buffer spring and the sliding friction between the outer wall of the movable block and the inner wall of the L-shaped sleeve are used to offset the impact force from the falling object, thereby better protecting the voltage transformer housing and preventing electrical safety accidents.

[0012] 2. By opening two ventilation openings on the surface of the voltage transformer housing, airflow can be accelerated, enabling the voltage transformer housing to dissipate heat quickly. Dustproof screens are installed inside the ventilation openings to prevent dust from entering the inside of the voltage transformer housing. Multiple louvers are movable inside the ventilation openings, which can be opened when heat dissipation is needed. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0019] As attached Figure 1-4 The single-phase outdoor voltage transformer housing shown includes a voltage transformer housing body 1, on which two insulating bottles 2 are installed.

[0020] In a specific embodiment, as shown in the appendix Figure 1 , 3 As shown in Figure 4, a protective structure is provided at the top of the voltage transformer housing body 1. The protective structure includes two support blocks 3, which are fixedly installed on the outer wall of the voltage transformer housing body 1. Each support block 3 has a screw 4 at its top and an adjusting block 5 outside the screw 4. The top and bottom of the adjusting block 5 are provided with locking nuts 6. The adjusting block 5 is slidably connected to the outside of the screw 4. The locking nuts 6 are installed outside the screw 4 and are threadedly connected to the screw 4. One end of the adjusting block 5 is provided with an L-shaped sleeve 7. A sleeve rod 8 is slidably installed inside the L-shaped sleeve 7. A protective plate 9 is installed at the top of the two sleeve rods 8. A movable block 10 is provided at the bottom of the sleeve rod 8 inside the L-shaped sleeve 7. A buffer spring 11 is provided at the bottom of the movable block 10. The outer wall of the movable block 10 is slidably connected to the inner wall of the L-shaped sleeve 7. The two ends of the buffer spring 11 are fixedly connected to the movable block 10 and the bottom of the inner cavity of the L-shaped sleeve 7, respectively.

[0021] Specifically, in this structure, the protective structure is used to protect the top of the voltage transformer housing 1 to prevent falling objects or rain and snow from affecting the voltage transformer housing 1. Specifically, firstly, the two adjusting blocks 5 slide outside the corresponding screw 4 to adjust the height of the entire protective plate 9. Then, by rotating the locking nut 6 on the external thread of the screw 4, the adjusted adjusting blocks 5 are limited. At this time, the protective plate 9 is located on the top of the voltage transformer housing 1 for protection.

[0022] In the event of a falling object, the protective plate 9 provides good protection. At the same time, it causes the sleeve rod 8 to slide inside the L-shaped sleeve 7, and the movable block 10 to slide and rub inside the L-shaped sleeve 7. This causes the buffer spring 11 to compress and return. The elasticity of the buffer spring 11 and the sliding friction between the outer wall of the movable block 10 and the inner wall of the L-shaped sleeve 7 are used to offset the impact force from the falling object, thus better protecting the voltage transformer housing 1 and preventing electrical safety accidents.

[0023] In a specific embodiment, as shown in the appendix Figure 1 , 2 As shown, ventilation openings 12 are provided on both sides of the outer wall of the voltage transformer housing 1. A dustproof net 13 is embedded inside the ventilation opening 12, and multiple louvers 14 are movably installed inside the ventilation opening 12 on one side of the dustproof net 13.

[0024] Specifically, in this structure, two ventilation openings 12 are opened on the surface of the voltage transformer housing 1 to accelerate airflow and enable the voltage transformer housing 1 to achieve rapid heat dissipation. A dustproof net 13 is installed inside the ventilation opening 12 to prevent dust from entering the inside of the voltage transformer housing 1. Multiple louvers 14 are movably installed inside the ventilation opening 12, and the louvers 14 can be opened or closed when heat dissipation is required.

[0025] In a specific embodiment, as shown in the appendix Figure 1 As shown, a mounting plate 15 is provided at the bottom of the voltage transformer housing 1. Several threaded holes are provided on the surface of the mounting plate 15, and bolts 16 are threadedly installed inside the several threaded holes.

[0026] Specifically, in this structure, the mounting plate 15 is installed at an outdoor location by bolts 16, thereby enabling the installation and removal of the voltage transformer housing 1.

[0027] Working principle of this utility model:

[0028] This application provides a single-phase outdoor voltage transformer housing. In specific operation, the voltage transformer housing body 1 is first installed in the outdoor use position using bolts 16 on the mounting plate 15.

[0029] The height of the protective plate 9 is adjusted by sliding the adjusting block 5 up and down outside the screw 4. The adjusting block 5 is then fixed by locking the nut 6. At this time, the protective plate 9 located on the top of the voltage transformer housing 1 can protect the voltage transformer housing 1. In the event of a falling object, the protective plate 9 will protect the voltage transformer housing 1. This will cause the sleeve rod 8 to slide inside the L-shaped sleeve 7 and the movable block 10 to slide and rub inside the L-shaped sleeve 7. This will cause the buffer spring 11 to be squeezed and return. The elasticity of the buffer spring 11 and the sliding friction between the outer wall of the movable block 10 and the inner wall of the L-shaped sleeve 7 will be used to offset the impact force from the falling object, thus better protecting the voltage transformer housing 1 and preventing electrical safety accidents.

[0030] The heat generated by the electrical components inside the voltage transformer housing 1 during operation is discharged through the ventilation port 12 to achieve the purpose of heat dissipation. The dustproof net 13 is used to prevent dust from entering the ventilation port 12, and the louvers 14 can be opened and closed to facilitate heat dissipation.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
