Description

Technical Field

[0001] The invention relates to the field of transformers, and in particular to an adjustable transformer with moisture-proof function. Background Art

[0002] Outdoor transformers need to face a complex external environment, especially when it rains. Waterproofing of the transformer connection parts is particularly important. When facing the waterproofing of the transformer connectors, a cover is usually set to cover the connectors. After the cover is set, rainwater is easily accumulated on the cover, which makes it easy for the high-voltage terminals to be connected in the case of water accumulation, resulting in a short circuit in the transformer. At the same time, when workers climb to the transformer location for maintenance, they need to carry tool bags and climb up the poles and stand on the transformer for maintenance. It is inconvenient for workers to maintain the transformer whether they carry tool bags or hold tools. Carrying tools will cause inconvenience to workers' movements and operations, and workers cannot find a good tool placement point on the transformer, resulting in the need for workers to hold tools to maintain the transformer at all times, resulting in inconvenience in maintenance.

[0003] At the same time, when maintaining the transformer, some small parts or bolts are easy to fall out of the hands. At this time, the workers are working at high altitude, and small parts or bolts are easy to injure passers-by. At the same time, small parts or bolts are also easy to get stuck in the cooling fins of the transformer, making it difficult for workers to remove them. Summary of the invention

[0004] In order to overcome the shortcomings of the existing cover shell that is prone to water accumulation leading to a short circuit between high-voltage terminals, and the need to always hold tools to maintain the transformer during maintenance, causing inconvenience in maintenance, and small parts or bolts are prone to falling and injuring pedestrians during maintenance, and small parts or bolts are also prone to getting stuck between the heat dissipation fins of the transformer and being difficult to remove, the present invention provides an adjustable transformer with a moisture-proof function.

DETAILED DESCRIPTION

[0018] The preferred technical solutions of the present invention are described in detail below with reference to the accompanying drawings.

[0019] Example 1 like Figure 1-Figure 3 As shown, an adjustable transformer with moisture-proof function includes a housing 1, fins 2 and high-voltage terminals 5; a plurality of fins 2 are arranged on the housing 1; a plurality of high-voltage terminals 5 are installed on the upper side of the housing 1; It also includes a protective cover 3, an adjusting cover 4, a shield 102 and a fan 103; a protective cover 3 is installed on the shell 1; a plurality of first air holes 3001 are provided on the protective cover 3; two adjusting covers 4 are rotatably connected to the shell 1; a plurality of second air holes 4001 are provided on each adjusting cover 4; a shield 102 is detachably connected to the upper side of the shell 1; a plurality of air inlet grooves 1001 are provided on the shell 1; a plurality of exhaust grooves 1002 are provided on the shell 1, and each exhaust groove 1002 is connected to each air inlet groove 1001; a plurality of fans 103 are fixedly connected in the shield 102; the lower side of the shield 102 is connected to the exhaust groove 1002.

[0020] It also includes guide pieces 101 ; each adjustment cover 4 is fixed with a plurality of guide pieces 101 ; each guide piece 101 is located directly above the adjacent fin 2 .

[0021] like Figure 2 As shown, each adjustment cover 4 can be unfolded and positioned above the adjacent fin 2 .

[0022] Each adjustment cover 4 is rotatably connected to the housing 1 , and each adjustment cover 4 is provided with a bearing portion 4002 .

[0023] The upper sides of the protective cover 3 and the adjusting cover 4 are both arranged in an inverted V shape to prevent rainwater accumulation and reduce the risk of rainwater penetration.

[0024] The protective cover 3 is slidably connected to the housing 1 .

[0025] Each air inlet groove 1001 is located at the lower side of the shell 1 , so that rainwater cannot flow along the shell 1 to the air inlet groove 1001 , thereby improving the waterproof effect at the air inlet groove 1001 .

[0026] After the housing 1 and the high-voltage terminal 5 are installed outdoors, they need to face many complex environments. In order to avoid leakage caused by rainwater eroding the high-voltage terminal 5, a protective cover 3 and an adjusting cover 4 are added to the housing 1 to cover the high-voltage terminal 5 as a whole, thereby blocking rainwater from eroding the high-voltage terminal 5 and making the high-voltage terminal 5 moisture-proof and waterproof. In this process, due to the addition of the protective cover 3 and the adjusting cover 4, when workers need to maintain the high-voltage terminal 5 later, they are blocked by the protective cover 3 and the adjusting cover 4, resulting in obstructions when workers maintain the high-voltage terminal 5. In order to avoid this phenomenon, the adjusting cover 4 is formed as follows: Figure 2 The protective cover 3 and the adjusting cover 4 can be unfolded to prevent the workers from being blocked by the protective cover 3 and the adjusting cover 4 when maintaining the high-voltage terminal 5. At the same time, after the adjusting cover 4 is unfolded, the workers can also put the tools they carry on the bearing part 4002, so that the workers do not need to hold the tools all the time when maintaining the high-voltage terminal 5, and the workers' hands can be freed to maintain the high-voltage terminal 5, thereby improving the convenience of the workers when maintaining the high-voltage terminal 5. Furthermore, when the two adjusting covers 4 are unfolded and located above the fins 2 on the front and rear sides respectively, the workers can stand on the front and rear sides of the shell 1 to maintain the high-voltage terminal 5. When there are small parts or bolts during the maintenance process, the unfolded adjusting cover 4 can also block and carry the small parts or bolts to prevent the small parts or bolts from falling into and getting stuck between the fins 2, making it difficult for the workers to remove them, and at the same time, prevent the small parts or bolts from injuring passers-by.

[0027] It is also considered that when the adjustment cover 4 is closed, the protective cover 3 and the adjustment cover 4 cover the high-voltage terminal 5, which will cause poor air flow in the high-voltage terminal 5 area, and then cause the heat dissipation effect of the high-voltage terminal 5 to deteriorate. In order to avoid this phenomenon, by installing a cover 102 and a fan 103 on the shell 1, when cooling is needed in summer, the fan 103 is started to rotate, and then the outside air enters from the air inlet groove 1001, and after passing through the inside of the shell 1, it is discharged from the exhaust groove 1002, and then rushes to the high-voltage terminal 5, and finally, under the guidance of the protective cover 3 and the adjustment cover 4, the gas is discharged from the first air hole 3001 and the second air hole 4001 respectively, and then the circulating gas is used to dissipate the heat of the high-voltage terminal 5 to avoid damage to the high-voltage terminal 5 due to excessive temperature. At the same time, the gas flowing through the shell 1 can also take away the heat generated by the heat-prone parts in the shell 1, thereby improving the overall heat dissipation capacity of the transformer. Furthermore, when the gas is discharged from the first air hole 3001 and the second air hole 4001, the guide plate 101 guides the gas The body is guided so that the airflow is also blown to the fin 2, thereby improving the airflow circulation effect in the fin 2 area, and further increasing the heat dissipation effect of the transformer. At the same time, the airflow can also blow away the dust attached to the surface of the fin 2 to prevent the accumulation of dust and cause the poor heat dissipation effect of the fin 2. Further, when facing a humid and cold environment, in order to prevent water vapor from contacting the high-voltage terminal 5 through the first air hole 3001 and the second air hole 4001, the fan 103 is started to make the first air hole 3001 and the second air hole 4001 always generate an outward airflow, thereby preventing water vapor from contacting the high-voltage terminal 5. At the same time, a desiccant is placed at the air inlet groove 1001 to prevent the gas entering the shell 1 from containing moisture. In this process, it is also considered that the airflow blown out from the shell 1 carries the heat of its internal parts. When the hot air blows to the protective cover 3 and the adjustment cover 4, the inside of the protective cover 3 and the adjustment cover 4 can also be dehumidified to keep the high-voltage terminal 5 dry, prevent the high-voltage terminal 5 from being corroded by water vapor, and improve the protection capability of the high-voltage terminal 5.

[0028] It is also taken into consideration that due to the gap between the protective cover 3 and the adjusting cover 4, impurities are easily accumulated in the gap between the protective cover 3 and the adjusting cover 4 during long-term use, which will cause the seal between the protective cover 3 and the adjusting cover 4 to be loose. In order to avoid this phenomenon, when the worker is maintaining the high-voltage terminal 5, the protective cover 3 is lifted up for a distance, and then the fan 103 is started to rotate, and the airflow is blown toward the front and rear sides of the protective cover 3 by guiding the lower side of the protective cover 3, and at the same time, it is blown toward the side of the adjusting cover 4 close to the protective cover 3, thereby blowing away the impurities accumulated between the protective cover 3 and the adjusting cover 4, and there is no need for the worker to clean and maintain the gap between the protective cover 3 and the adjusting cover 4.

[0029] Example 2 On the basis of Example 1, Figure 1 , Figure 4 and Figure 5As shown, a pad strip 201 is also included; each adjustment cover 4 is fixed with a pad strip 201 on one side facing the protective cover 3; the protective cover 3 is higher than the adjustment cover 4 as a whole, and the front and rear sides of the protective cover 3 partially cover the upper part of the adjacent adjustment cover 4.

[0030] Each gasket strip 201 is respectively fitted with the front side and the rear side of the protective cover 3 to improve the sealing between the protective cover 3 and the adjustment cover 4 and prevent rainwater from flowing into the housing 1 through the gap between the adjustment cover 4 and the protective cover 3 .

[0031] Each gasket strip 201 is made of rubber material to enhance the sealing effect between the protective cover 3 and the adjustment cover 4 .

[0032] When the adjusting cover 4 is unfolded, considering that the worker is easily scratched by the side of the adjusting cover 4 when leaning on the adjusting cover 4 to maintain the high-voltage terminal 5, a pad 201 is set on the side of the adjusting cover 4, so that the worker can be cushioned and protected by the pad 201 when leaning on the adjusting cover 4, and the comfort of the worker during maintenance is improved. Furthermore, when the adjusting cover 4 is closed, the pad 201 on the side of the adjusting cover 4 fits on the front and rear sides of the protective cover 3, thereby increasing the sealing effect between the protective cover 3 and the adjusting cover 4, and further improving the device's ability to protect against rainwater. At the same time, since the protective cover 3 is higher than the adjusting cover 4 as a whole, when rainwater flows along the protective cover 3 to the adjusting cover 4, the front and rear sides of the protective cover 3 are partially covered above the adjacent adjusting cover 4, so that the rainwater passes through the gap between the protective cover 3 and the adjusting cover 4 and directly flows to the upper side of the adjusting cover 4, further improving the device's ability to intercept rainwater.
