Description

Technical Field

[0001] The utility model relates to the technical field of transformer housings, in particular to a transformer housing which is convenient for temperature control. 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, dry-type transformers refer to transformers whose cores and windings are not immersed in insulating oil. Their cooling methods are divided into natural air cooling and forced air cooling.

[0003] There are obvious differences between the current dry-type transformers and oil-immersed transformers. In order to ensure that they can effectively dissipate heat, air holes are opened on both sides and the surface of the box to ensure air circulation to achieve the purpose of heat dissipation. However, although such a setting can effectively dissipate heat, it still has obvious defects in actual use, such as:

[0004] The transformer needs to be cooled by flowing air. However, in the rainy season, the humidity in the air is high. Allowing the air to circulate inside the box will cause the humidity inside the box to increase, which will damage the transformer equipment inside. The existing transformer box does not have a dehumidification function, and it is impossible for the staff to know the internal temperature status in time, making it difficult to control the temperature of the equipment.

[0005] Therefore, a transformer housing that can dehumidify and is convenient for workers to know and is easy to temperature control is now designed to solve such defects. Utility Model Content

[0006] In view of the deficiencies of the prior art, the utility model provides a transformer housing that is easy to temperature control, which solves the problem that the prior transformer housing cannot be dehumidified and the temperature inside the housing cannot be well controlled.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: a transformer housing that is easy to control temperature, including a transformer box, a ventilation groove is opened at the lower part of the surface of the transformer box, and an absorption hole that penetrates into the ventilation groove is opened at the bottom of the inner cavity of the transformer box. A temperature detector and a humidity detector are fixedly connected to the two sides of the top of the transformer box through openings, and a ventilation fan is fixedly installed on the top of the transformer box through the opening.

[0008] Preferably, both sides of the inner cavity of the ventilation slot are fixedly connected with slide slot plates, a containing frame is slidably installed between the inner sides of the two slide slot plates, and both sides of the transformer box body are opened with side slots, and a plurality of side slots are provided.

[0009] Preferably, sliding openings are provided on both sides of the top of the absorption hole, and a sealing plate is slidably installed on the inner side of the sliding opening. A retreat plate is fixedly connected between the two sealing plates through a bracket, and the retreat plate is located on the inner side of the ventilation groove, and a spring is fixedly connected between the two sides of the rear part of the retreat plate and the rear part of the inner cavity of the ventilation groove.

[0010] Preferably, a rectangular opening is provided on the surface of the anti-rebound plate and extends to the rear, a threaded barrel is fixedly connected to the surface of the containing frame through the opening, and the rear end of the threaded barrel passes through the containing frame and extends to the rear of the containing frame, a threaded rod is threadedly connected to the inner side of the threaded barrel, and a threaded cap used in conjunction with the threaded rod is fixedly connected to the rear of the inner cavity of the ventilation groove.

[0011] Preferably, a button for use with a backstop plate is fixedly mounted on the left side of the rear portion of the inner cavity of the ventilation slot. Beneficial Effects

[0012] The utility model provides a transformer housing that is easy to control temperature. Compared with the existing technology, it has the following beneficial effects:

[0013] (1) The transformer housing that is easy to control temperature has a temperature detector and a humidity detector installed on the top of the transformer housing, and a containing frame is arranged inside the ventilation slot, which is used in conjunction with side slots and buttons. The arrangement of these structures enables the staff to quickly know the temperature and humidity inside the transformer housing through the temperature detector and the humidity detector, and after knowing the temperature and humidity, they can place lime inside the containing frame and reverse the ventilation fan. At the same time, the side slots are closed by the linkage between the structures, thereby reducing the air flow rate inside the transformer housing, and absorbing the moisture in the air inside the transformer housing to reduce the internal humidity, thereby achieving effective protection for the equipment and facilitating the staff to control the temperature of the equipment.

[0014] (2) The transformer housing that is easy to control temperature is installed with a threaded cap on the rear side of the ventilation slot, and is used in conjunction with a threaded tube and a threaded rod. The arrangement of these structures can use the holding frame to press the backstop plate so that the two sealing plates close the side slots, and after the threaded rod and the threaded cap are connected, the holding frame, the sealing plate and the button are fixed, thereby ensuring the stability of the equipment during dehumidification and improving the overall functionality of the equipment.

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-5 The utility model provides a technical solution: a transformer housing that is easy to control temperature, including a transformer box 1, a ventilation slot 2 is provided at the lower part of the surface of the transformer box 1, an absorption hole 3 that penetrates into the ventilation slot 2 is provided at the bottom of the inner cavity of the transformer box 1, a temperature detector 6 and a humidity detector 7 are fixedly connected to the two sides of the top of the transformer box 1 through openings, a ventilation fan 8 is fixedly installed on the top of the transformer box 1 through openings, and the ventilation fan 8 can rotate forward and reverse, both sides of the inner cavity of the ventilation slot 2 are fixedly connected with slide plates 4, a containing frame 5 is slidably installed between the inner sides of the two slide plates 4, and side grooves 9 are provided on both sides of the transformer box 1, and a plurality of side grooves 9 are provided.

[0023] During use, the staff knows the temperature and humidity inside the transformer box 1 by observing the temperature detector 6 and the humidity detector 7. When the weather is dry, the side slots 9 are opened and the ventilation fan 8 is started to blow air into the transformer box 1. The side slots 9 on both sides can provide air flow to achieve cooling. If the weather is humid, the staff places lime powder on the inside of the containing frame 5, and then uses the slide plate 4 to insert the containing frame 5 into the inside of the ventilation slot 2. After the containing frame 5 completely enters the interior of the ventilation slot 2, the containing frame 5 will push the retreat plate 12, thereby driving the two sealing plates 11 to move backwards and overlap with the side slots 9 to close the side slots 9, and then rotate the threaded rod 16 to dock with the threaded cap 17. At this time, the containing frame 5 and the side slots 9 are fixed.

[0024] Furthermore, sliding openings 10 are provided on both sides of the top of the absorption hole 3, and a sealing plate 11 is slidably installed on the inner side of the sliding opening 10. A back-stop plate 12 is fixedly connected between the two sealing plates 11 through a bracket, and the back-stop plate 12 is located on the inner side of the ventilation slot 2, and springs 13 are fixedly connected between the two sides of the rear of the back-stop plate 12 and the rear of the inner cavity of the ventilation slot 2. A rectangular opening 14 is provided on the surface of the back-stop plate 12 that extends to the rear, and a threaded barrel 15 is fixedly connected to the surface of the containing frame 5 through an opening, and the rear end of the threaded barrel 15 penetrates the containing frame 5 and extends to the rear of the containing frame 5, and a threaded rod 16 is threadedly connected to the inner side of the threaded barrel 15, and a threaded cap 17 used in conjunction with the threaded rod 16 is fixedly connected to the rear of the inner cavity of the ventilation slot 2, and a button 18 used in conjunction with the back-stop plate 12 is fixedly installed on the left side of the rear of the inner cavity of the ventilation slot 2.

[0025] When the button 18 is pressed, the ventilation fan 8 is started in reverse to draw the air inside the transformer box 1 out. At this time, due to the closure of the side grooves 9, the entry of humid air from the outside is reduced, and the moisture inside the transformer box 1 will be continuously absorbed by the lime, thereby reducing the humidity inside the transformer box 1 and reducing damage to the transformer. After dehumidification is completed, the threaded rod 16 is twisted to draw the containing frame 5 out of the ventilation groove 2, and the button 18 is no longer pressed, so that the ventilation fan 8 blows air again to dissipate heat and cool the inside of the transformer box 1.

[0026] Meanwhile, the contents not described in detail in this specification belong to the prior art known to those skilled in the art.
