Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a rainproof dry-type transformer. Background Art

[0002] Dry-type transformers are widely used in local lighting, high-rise buildings, airports, docks, CNC machinery and equipment and other places. Simply put, a dry-type transformer refers to a transformer whose core and winding are not immersed in insulating oil.

[0003] A Chinese patent application CN202020169078.7 discloses a dry-type transformer. The key points of its technical solution are: the transformer body, the supporting base and the lifting top seat are symmetrically fixed by springs, so that the upper and lower sides of the transformer body are symmetrically compressed with equal force, which plays an excellent buffering role, reduces the swinging impact on the transformer body, and effectively extends the service life of the dry-type transformer.

[0004] In view of the above and existing related technologies, the inventors believe that the following defects often exist: dry-type transformers are used in many places and may often be placed outdoors. On rainy days, rain directly falls on the transformer body, causing water to enter the transformer body, thereby causing short-circuit damage to the transformer body; therefore, a rainproof dry-type transformer is proposed to address the above problems. Utility Model Content

[0005] The utility model aims to solve the defect in the prior art that water enters the transformer body, thus causing short circuit damage to the transformer body, and proposes a rainproof dry-type transformer.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a rainproof dry-type transformer, comprising a transformer body, a placement plate is installed on the lower surface of the transformer body, a protective device is provided on the surface of the placement plate, the protective device comprises a protective frame, the protective frame is fixedly connected to the surface of the placement plate, two sliding grooves are provided on the surface of the placement plate, a protective box is slidably connected to the inner surfaces of the two sliding grooves of the placement plate, the surface of the protective box is slidably connected to the protective frame, a protective door is slidably inserted in the protective frame, and an operating block is fixedly connected to the surface of the protective door.

[0007] The effect achieved by the above components is: by setting up the protective device, the transformer body can be protected from rain on rainy days, avoiding rainwater directly pouring on the transformer body on rainy days, causing water to enter the transformer body, thereby causing short-circuit damage to the transformer body, thereby improving the protectiveness of the device.

[0008] Preferably, both sides of the protective frame are fixedly connected with L-shaped plates, a driving rod is inserted into the internal thread of the L-shaped plate, one end of the driving rod is rotatably connected with a connecting block, and both sides of the protective box are fixedly connected with connecting plates, and the surface of the connecting plates is provided with connecting grooves.

[0009] The effect achieved by the above components is: the protective box is fixed and limited, which prevents the protective box from being hit by external factors when protecting the transformer body, causing the protective box to detach from the protective frame, thereby affecting the protective effect of the protective box.

[0010] Preferably, a positioning rod is fixedly connected to one side of the connection block close to the driving rod, and the arc surface of the positioning rod is slidably connected to the L-shaped plate.

[0011] The effect achieved by the above components is that the positioning rod achieves the effect of limiting the connection block from rotating along with the driving rod, so that the staff can quickly and accurately insert the connection block into the connection groove of the connection plate.

[0012] Preferably, an auxiliary device is provided on the surface of the protective frame, and the auxiliary device includes two fixing rods, both of which are fixedly connected to the surface of the protective frame, and the arc surface of the fixing rod is slidably connected to an operating plate, and the operating plate is fixedly connected to a plug rod on the side close to the protective frame, and the surface of the protective door is fixedly connected to two connecting blocks, and the surface of the connecting blocks is provided with slots.

[0013] The effect achieved by the above components is: by setting the auxiliary device, the effect of fixing the opened protective door is achieved, which avoids the situation where the opened protective door slides back and forth in the protective frame when the staff needs to check the transformer body, causing the staff to have to free up one hand to fix the protective door, thereby affecting the work of the staff, thereby improving the practicability of the device.

[0014] Preferably, one end of the fixing rod away from the protection frame is fixedly connected to a limiting plate, and the size of the insertion rod is matched with the size of the connection block slot.

[0015] The effect achieved by the above components is: the limit plate limits the maximum sliding distance of the operating plate on the arc surface of the fixed rod, thereby preventing the operating plate from detaching from the arc surface of the fixed rod due to excessive pulling force when the staff pulls the operating plate.

[0016] Preferably, the arc surface of the fixing rod is sleeved with a first spring, and two ends of the first spring are respectively fixedly connected to the operating plate and the protective frame.

[0017] The effects achieved by the above components are as follows: the first spring improves the stability of the insertion rod when limiting the connection block, and at the same time improves the stability of the insertion rod when limiting the protective door.

[0018] In summary, the beneficial effects of the utility model are:

[0019] 1. In the utility model, by setting a protective device, the transformer body is protected from rain on rainy days, which prevents rain from directly pouring on the transformer body on rainy days, causing water to enter the transformer body, thereby causing short-circuit damage to the transformer body, thereby improving the protectiveness of the device.

[0020] 2. In the utility model, by setting an auxiliary device, the effect of fixing the opened protective door is achieved, which avoids the situation where the opened protective door slides back and forth in the protective frame when the staff needs to check the transformer body, causing the staff to have to free up one hand to fix the protective door, thereby affecting the work of the staff, thereby improving the practicality of the device.

[0026] Reference Figure 1As shown, the utility model provides a technical solution: a rainproof dry-type transformer, comprising a transformer body 1, a placement plate 2 is installed on the lower surface of the transformer body 1, and a protective device 3 is provided on the surface of the placement plate 2. By providing the protective device 3, the transformer body 1 is protected from rain on rainy days, thereby preventing rain from directly pouring on the transformer body 1 on rainy days, causing water to enter the transformer body 1, thereby causing short-circuit damage to the transformer body 1, and improving the protectiveness of the device. An auxiliary device 4 is provided on the surface of the protective frame 31. By providing the auxiliary device 4, the protective door 33 is fixed after it is opened, thereby preventing the staff from sliding back and forth in the protective frame 31 when the staff needs to check the transformer body 1, causing the staff to have to free up one hand to fix the protective door 33, thereby causing a situation that affects the work of the staff, and improving the practicality of the device.

[0027] The specific settings and functions of the protective device 3 and the auxiliary device 4 are described in detail below.

[0028] Reference Figure 2 and Figure 3 As shown, in this embodiment: the protection device 3 includes a protection frame 31, the protection frame 31 is fixedly connected to the surface of the placement plate 2, the surface of the placement plate 2 is provided with two sliding grooves, the inner surfaces of the sliding grooves of the two placement plates 2 are slidably connected with a protection box 32, the surface of the protection box 32 is slidably connected to the protection frame 31, a protection door 33 is slidably inserted in the protection frame 31, the surface of the protection door 33 is fixedly connected with an operating block 34, both sides of the protection frame 31 are fixedly connected with L-shaped plates 35, the L-shaped plate 35 is internally threaded with a driving rod 36, one end of the driving rod 36 is rotatably connected with a connecting block 37, both sides of the protection box 32 are fixedly connected with connecting plates 38, and the surface of the connecting plate 38 is provided with a connecting groove. When the staff protects the transformer body 1, the driving rod 36 is rotated to make the driving rod 36 move in the internal thread of the L-shaped plate 35, and at the same time, the driving rod 36 drives the connecting block 37 to move, until When the connecting block 37 is inserted into the connecting groove of the connecting plate 38, the protective box 32 is fixedly limited. When the protective box 32 protects the transformer body 1, the protective box 32 is prevented from being hit by the outside world, causing the protective box 32 to detach from the protective frame 31, thereby affecting the protective effect of the protective box 32. A positioning rod 39 is fixedly connected to the side of the connecting block 37 close to the driving rod 36. The arc surface of the positioning rod 39 is slidably connected to the L-shaped plate 35. When the staff rotates the driving rod 36, the driving rod 36 moves in the internal thread of the L-shaped plate 35. At the same time, the driving rod 36 drives the connecting block 37 to move, and the connecting block 37 drives the positioning rod 39 to slide in the L-shaped plate 35. At this time, the positioning rod 39 achieves the effect of limiting the connection block 37 from following the rotation of the driving rod 36, so that the staff can quickly and accurately insert the connecting block 37 into the connecting groove of the connecting plate 38.

[0029] Reference Figure 4 As shown, specifically, the auxiliary device 4 includes two fixed rods 41, both of which are fixedly connected to the surface of the protective frame 31, and the arc surface of the fixed rod 41 is slidably connected with an operating plate 42, and the side of the operating plate 42 close to the protective frame 31 is fixedly connected with an insertion rod 43, and the surface of the protective door 33 is fixedly connected with two connecting blocks 44, and the surface of the connecting block 44 is provided with a slot, and the end of the fixed rod 41 away from the protective frame 31 is fixedly connected to a limiting plate 45, and the size of the insertion rod 43 is adapted to the size of the slot of the connecting block 44. When the staff pulls the operating plate 42, the operating plate 42 slides on the arc surface of the fixed rod 41, and at this time, the limiting plate 45 reaches the limit of the sliding of the operating plate 42 on the arc surface of the fixed rod 41 The effect of the maximum distance prevents the operating plate 42 from detaching from the arc surface of the fixing rod 41 due to excessive pulling force when the staff pulls the operating plate 42. The arc surface of the fixing rod 41 is sleeved with a first spring 46, and the two ends of the first spring 46 are respectively fixedly connected to the operating plate 42 and the protective frame 31. When the staff releases the operating plate 42, the rebound force of the first spring 46 drives the operating plate 42 to slide on the arc surface of the fixing rod 41, and at the same time, the operating plate 42 drives the insertion rod 43 to move until the insertion rod 43 is inserted into the slot of the connecting block 44. At this time, the first spring 46 improves the stability of the insertion rod 43 when limiting the connecting block 44, and at the same time improves the stability of the insertion rod 43 when limiting the protective door 33.

[0030] Working principle: when the staff needs to protect the transformer body 1 from rain on a rainy day, they pull the protection box 32 to make the protection box 32 slide in the sliding groove of the placement plate 2 until the protection box 32 is inserted into the protection frame 31, and at the same time press the operating block 34, the operating block 34 drives the protection door 33 to slide in the protection frame 31 until the protection door 33 completely blocks the transformer body 1, at this time, rotate the driving rod 36 to make the driving rod 36 move in the L-shaped plate 35 inner thread, and at the same time, the driving rod 36 drives the connecting block 37 to move, and the connecting block 37 drives the positioning rod 39 to slide in the L-shaped plate 35 until the connecting block 37 is inserted into the connecting groove of the connecting plate 38, at this time, the effect of protecting the transformer body 1 from rain on rainy days is achieved, and rainwater is avoided from directly pouring on the transformer body 1 on rainy days, causing water to enter the transformer body 1, thereby causing short-circuit damage to the transformer body 1, thereby improving the protection of the device.

[0031] When the staff needs to check the transformer body 1, they pull the operating plate 42 to make the operating plate 42 slide on the arc surface of the fixing rod 41, the first spring 46 is stretched, and the operating plate 42 drives the plug rod 43 to move until the plug rod 43 no longer blocks the movement of the connecting block 44. At this time, the operating block 34 is pulled, and the operating block 34 drives the protective door 33 to move until the protective door 33 is fully opened. At this time, the operating plate 42 is released, and the resilience of the first spring 46 drives the operating plate 42 to slide on the arc surface of the fixing rod 41, and the operating plate 42 drives the plug rod 43 to move until the plug rod 43 is inserted into the slot of the connecting block 44. At this time, the protective door 33 is fixed after opening, avoiding that the opened protective door 33 slides back and forth in the protective frame 31 when the staff needs to check the transformer body 1, causing the staff to have to free up one hand to fix the protective door 33, thereby causing a situation that affects the work of the staff, thereby improving the practicability of the device.
