[0035] This invention proposes a dry-type transformer casing.

[0036] like Figures 1 to 3 The dry-type transformer housing shown includes a main enclosure 1, a door 11, a base plate 3, and an adjustment enclosure 2. A slide rail is provided on one side of the base plate 3. Both the main enclosure 1 and the adjustment enclosure 2 are located on the side of the base plate 3 with the slide rail, which extends from the main enclosure 1 towards the adjustment enclosure 2. The sides of the main enclosure 1 and the adjustment enclosure 2 closest to the base plate 3 are open. The door 11 is located on the side of the main enclosure 1 away from the adjustment enclosure 2, and the side of the main enclosure 1 away from the door 11 is the first open. The side of the adjustment enclosure 2 facing the main enclosure 1 is the second open. The side of the main enclosure 1 with the first open enters the adjustment enclosure 2 through the second open. The main enclosure 1 and the adjustment enclosure 2 together form a receiving space for accommodating the dry-type transformer. The adjustment enclosure 2 is slidably connected to the slide rail, and the adjustment enclosure 2 is used to slide along the slide rail to adjust the dimensions of the receiving space along the extension direction of the slide rail.

[0037] Adjusting the housing 2 moves along the slide rail to adjust the size data of the accommodating space, so that the adjustment housing 2 and the main housing 1 can be adjusted according to the actual situation. This facilitates the early production of the adjustment housing 2 and the main housing 1, so that the dry-type transformer shell composed of the adjustment housing 2, the main housing and the base plate 3 can meet the size requirements of most dry-type transformers on the market, and improve the delivery efficiency of the dry-type transformer shell.

[0038] The dry-type transformer casing also includes a connecting mechanism 4, which is located at the bottom of the adjusting housing 2. The connecting mechanism 4 is slidably connected to the sliding housing and is used to drive the adjusting housing 2 to move along the slide rail. After adjusting the size data of the accommodating space, the relative position of the adjusting housing 2 and the main housing 1 is fixed. The connecting mechanism 4 facilitates the fixing of the relative position of the adjusting housing 2 and the main housing 1, thereby ensuring the structural strength of the dry-type transformer casing.

[0039] The slide includes a main slide groove 31 and two connecting slide grooves 32. The two connecting slide grooves 32 are arranged in parallel and spaced apart. The main slide groove 31 is located between the two connecting slide grooves 32 and is parallel to the two connecting slide grooves 32. The main slide groove 31 extends along the main housing 1 towards the adjusting housing 2. The connecting mechanism 4 includes a first slide block 41 and two pulleys 42. The adjusting housing 2 includes a first side plate and two second side plates. The first side plate is located away from the main housing 1. The first slide block 41 is located at the bottom end of the first side plate and is slidably connected to the main slide groove 31. The two second side plates are respectively connected to the first side plate. A second opening is formed between the ends of the two second side plates away from the first side plate. One pulley 42 is located at the bottom end of one side plate and is connected to one of the connecting slide grooves 32. The other pulley 42 is located at the bottom end of the other side plate and is connected to the other connecting slide groove 32.

[0040] Specifically, the two pulleys 42 are positioned close to the second opening, and the first slide block 41 and the two pulleys 42 form a triangular support, which can ensure the stability of the adjustment box 2 when it moves.

[0041] The bottom of the main slide groove 31 has several first fixing screw holes (not shown in the figure), which are spaced apart along the extension direction of the main slide groove 31. The first slide block 41 is located on the side of the first side plate facing the receiving space. The first slide block 41 has a first threaded through hole (not shown in the figure). The first slide block 41 is used to drive the adjusting housing 2 to move to the corresponding position along the main slide groove 31 according to the body shape data of the dry-type transformer, so that the screw connects the first threaded through hole and one of the first fixing screw holes in sequence, thereby fixing the adjusting housing 2 and the main housing 1. The first slide block 41 is fixed in the main slide groove 31 by the screw, which serves a fixing function. The first slide block 41 is located in the receiving space, which can prevent external personnel from disassembling it.

[0042] Specifically, the first threaded through hole and each of the first fixing screw holes are vertically arranged.

[0043] Specifically, the second side panel and the adjacent side panel of the main housing 1 are fixed with bolts, which further strengthens the connection between the main housing 1 and the adjusting housing 2.

[0044] The base plate 3 is also equipped with a limiting slide groove 33 and two limiting mechanisms 5. The limiting slide groove 33 is located inside the main housing 1 and is positioned at the end of the slide rail away from the adjusting housing 2. The limiting slide groove 33 is perpendicular to the slide rail. The two limiting mechanisms 5 are slidably connected to the limiting slide groove 33, forming a clamping space between them. The clamping space is used to fix the dry-type transformer located in the receiving space. The limiting mechanisms 5 allow for further adjustment of the size of the receiving space, so that the two limiting mechanisms 5 cooperate to clamp and fix the dry-type transformer.

[0045] The limiting mechanism 5 includes a second slide block 51 and a limiting plate 52. The second slide block 51 is slidably connected to the limiting groove 33. The limiting plate 52 is vertically disposed on the side of the second slide block 51 near the clamping space. A flexible layer 53 is disposed on the side of the limiting plate 52 facing the clamping space. The flexible layer 53 can reduce vibration and avoid the problem of rigid contact.

[0046] The bottom of the limiting slide groove 33 is provided with several second fixing screw holes (not shown in the figure), and each second fixing screw hole is spaced apart along the extension direction of the limiting slide groove 33; the second slide block 51 is provided with a second threaded through hole (not shown in the figure), and the two second slide blocks 51 are used to drive the limiting plate 52 closer to or further away from the clamping space according to the body data of the dry-type transformer, so that the two limiting plates 52 clamp the dry-type transformer located in the clamping space; the second slide block 51 is also used to connect the second threaded through hole and one of the second fixing screw holes in sequence through a screw, so as to fix the relative position of the second slide block 51 and the base plate 3.

[0047] Specifically, the two second threaded through holes and each second fixing screw hole are all set vertically.

[0048] The dry-type transformer casing is also equipped with a cooling mechanism 6 and a drive mechanism 7. The cooling mechanism 6 includes a cooler (not shown in the figure), a telescopic hose (not shown in the figure), and a cold air nozzle 61. The cooler is located in the main housing 1 or the adjustment housing 2. The telescopic hose and the cold air nozzle 61 are both located inside the main housing 1. One end of the telescopic hose is connected to the cold air inlet of the cooler, and the other end of the telescopic hose is connected to the cold air nozzle 61. The drive mechanism 7 is located in the housing space. The drive mechanism 7 drives the cold air nozzle 61. The drive mechanism 7 is used to drive the cold air nozzle 61 to face the temperature abnormal area of ​​the dry-type transformer, so that the cooler sprays cold air into the temperature abnormal area through the cold air nozzle 61.

[0049] The accommodating space is equipped with a connecting rail 71 and two adjusting rails 72, which are arranged in parallel and spaced apart, forming a working space between them. The working space is used to accommodate the dry-type transformer located in the accommodating space. The connecting rail 71 is located between the two adjusting rails 72 and is parallel to the slide rail. The two adjusting rails 72 are perpendicular to the connecting rail 71. One adjusting rail 72 is located on the top plate inside the main housing 1, and the other adjusting rail 72 is located on the top plate inside the adjusting housing 2. The connecting rail 71 connects to the two adjusting rails 72 respectively. The driving mechanism 7 includes an electrically controlled slide 73 and a lifter 74. The electrically controlled slide 73 is slidably connected to the connecting rail 71, and the lifter 74 is located on the side of the electrically controlled slide 73 facing the bottom plate 3. The output end of the lifter 74 drives the cold air nozzle 61.

[0050] Specifically, the dry-type transformer casing also includes a controller and a thermal imager 62. The thermal imager 62 is mounted on the cooling air nozzle 61. The controller is electrically connected to the thermal imager 62 and the electrically controlled slide 73. The thermal imager 62 is used to acquire a top-down heat distribution map of the dry-type transformer and send it to the controller. The controller determines whether the current temperature of the dry-type transformer is abnormal based on the top-down heat distribution map. When the current temperature of the dry-type transformer is normal, the controller controls the electrically controlled slide 73 to drive the cooling air nozzle 61 to be positioned directly above the clamping space, so that the cooling air nozzle 61 sprays cooling air onto the dry-type transformer. When the current temperature of the dry-type transformer is abnormal, the controller... Based on the first heat distribution diagram, the location of the abnormal temperature area is determined. When the abnormal temperature area is located on the side of the dry transformer near the door 11, the controller first controls the electric sliding block 73 to enter the adjustment track 72 located in the main housing 1, and then controls the lifter 74 to make the cold air nozzle 61 spray cold air close to the side of the dry transformer near the door 11. When the abnormal temperature area is located on the side of the dry transformer away from the door 11, the controller first controls the electric sliding block 73 to enter the adjustment track 72 located in the adjustment housing 2, and then controls the lifter 74 to make the cold air nozzle 61 spray cold air close to the side of the dry transformer away from the door 11.

[0051] The refrigeration mechanism 6 also includes a connecting pipe 68, which is vertically arranged. A lifting device 74 drives the connecting pipe 68 to move vertically. The end of the telescopic hose away from the refrigeration unit is connected to the connecting pipe 68. A cold air nozzle 61 is located at the end of the connecting pipe 68 away from the lifting device 74, and the connecting pipe 68 is connected to the cold air nozzle 61.

[0052] Specifically, the refrigeration mechanism 6 also includes a frame 63, a stepper motor 64, a guide wheel 65, a connecting cable 66, and a connecting hose 67. The output end of the lifter 74 and the top end of the connecting pipe 68 are connected through the frame 63. One end of the connecting hose 67 is connected to the bottom end of the connecting pipe 68, and the other end of the connecting pipe 68 is connected to the cold air nozzle 61. The guide wheel 65 is rotatably installed inside the frame 63. The output end of the stepper motor 64 drives the connecting guide wheel 65, and the stepper motor 64 is used to drive the guide wheel 65 to rotate. The connecting cable 66 is wound around the guide wheel 65, and the two ends of the connecting cable 66 are respectively connected to the cold air nozzle 61. The controller is electrically connected to the stepper motor 64. The controller is used to control the stepper motor 64 to drive the guide wheel 65 to rotate forward and backward according to the downward heat distribution map, so that the guide wheel 65 rotates forward and backward to drive the cold air nozzle 61 to swing along the length of the connecting track 71, and spray cold air from the cold air nozzle 61 to the abnormal temperature area.

[0053] Specifically, the thermal imager 62 is also used to acquire the frontal heat distribution map of the dry-type transformer and send it to the controller after the electrically controlled slide 73 moves to any of the adjustment tracks 72. The controller controls the lift 74 and the electrically controlled slide 73 respectively according to the frontal heat distribution map so that the cold air nozzle 61 sprays cold air directly at the highest temperature point in the frontal heat distribution map.

[0054] The above description is merely a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
