Description

Technical Field

[0001] This utility model relates to the field of electrical engineering technology, and in particular to a moisture-proof and condensation-proof protective cover for power equipment in substations. Background Technology

[0002] Electrical engineering is a core and key discipline in modern science and technology, encompassing almost all engineering activities related to electronics and photonics. It primarily studies the generation, transmission, distribution, and use of electricity, as well as the design and application of control systems. Electrical engineering not only focuses on the stability and safety of power systems but also involves the maintenance and management of electrical equipment to ensure the normal operation of the power system. Furthermore, with the development of information technology, electrical engineering has also become closely integrated with computer technology, promoting the development of industrial automation and intelligence.

[0003] One type of electrical equipment is the transformer, which works by changing the magnitude of alternating current (AC) voltage and current through electromagnetic induction. When an AC current flows through the primary coil, an AC magnetic flux is generated in the iron core (or magnetic core), inducing a voltage (or current) in the secondary coil. A transformer consists of an iron core (or magnetic core) and coils. The coils have two or more windings, with the winding connected to the power source called the primary coil and the remaining windings called secondary coils.

[0004] In the existing technology, some of the housings used to house transformers are made of semi-transparent plastic panels. Although this type of panel makes it easy to observe the overall condition of the transformer inside, it has poor moisture resistance and cannot prevent condensation from entering the housing from the connection between the cover and the housing, which can damage the transformer and reduce its service life. Therefore, a moisture-proof and condensation-proof protective cover for substation power equipment is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a moisture-proof and condensation-proof protective cover for substation power equipment. It aims to improve the problem that some of the existing transformer housings are made of semi-transparent plastic sheets, which have poor moisture resistance and cannot prevent condensation from entering the housing from the connection between the cover and the housing, causing damage to the transformer and reducing its service life.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A moisture-proof and condensation-proof protective cover for substation power equipment includes a housing, a top cover rotatably connected to the top of the housing, multiple transformers fixedly connected to the bottom of the inner wall of the housing, multiple bundled tube coils fixedly connected to the front of the housing, connecting wires fixedly connected to the inner walls of the transformers, the outer side of the connecting wires contacting the inner wall of the bundled tube coils, a locking assembly for connecting the housing and the top cover fixedly connected to the front of the top cover, a rubber ring fixedly connected to the inner wall of the housing, a rubber block slidably connected to the inner wall of the rubber ring, and a sleeve plate fixedly connected to the bottom of the top cover.

[0008] As a further description of the above technical solution:

[0009] Two side blocks are fixedly connected to both the left and right sides of the housing, and bolts are detachably connected to the inner wall of the side blocks;

[0010] As a further description of the above technical solution:

A second locking plate is fixedly connected to the front end of the housing. Two sliding pillars are slidably connected to the inner wall of the second locking plate. Limiting blocks are fixedly connected to adjacent sides of the two sliding pillars, and locking balls are fixedly connected to adjacent sides of the two limiting blocks. The locking balls and the locking blocks are engaged. A spring is sleeved on the outside of the sliding pillars.

[0012] As a further description of the above technical solution:

[0013] A limiting strip is fixedly connected to the bottom end of the rubber block, and a second spring is fixedly connected to one side of the limiting strip. The other end of the second spring is fixedly connected to one side of the inner wall of the rubber ring.

[0014] As a further description of the above technical solution:

[0015] The bottom end of the first card plate is in contact with the top end of the second card plate, and the outer side of the card block is slidably connected to the inner wall of the second card plate.

[0016] As a further description of the above technical solution:

[0017] The limiting block is externally slidably connected to the inner wall of the second clamping plate, and the clamping ball is externally slidably connected to the inner wall of the second clamping plate.

[0018] As a further description of the above technical solution:

[0019] One end of the spring is fixedly connected to one side of the inner wall of the card plate, and the other end of the spring is fixedly connected to one side of the limiting block.

[0020] As a further description of the above technical solution:

[0021] The bottom end of the sleeve plate contacts the top end of the rubber ring, and the outer side of the limiting strip is slidably connected to the inner wall of the rubber ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the shell and top cover are closed, the rubber block is inserted into the inside of the sleeve plate, and the spring at this point is squeezed, thereby releasing the reaction force, making the rubber block squeeze the inner wall of the sleeve plate more tightly, ensuring that condensation will not enter from the gap between the shell and the top cover, ensuring the normal operation of the transformer, and thus improving the service life of the transformer.

[0024] 2. In this utility model, when the transformer needs to be repaired, the top cover can be directly lifted, so that the locking block squeezes the locking ball, and the locking ball retracts into the interior of the second locking plate to complete the quick opening operation, which improves the speed of repair. After the repair is completed, the top cover can be rotated again to make the locking block squeeze the locking ball again to reset it. Attached Figure Description

[0032] 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.

[0033] Reference Figures 1 to 3 This utility model provides an embodiment of a moisture-proof and anti-condensation protective cover for substation power equipment, comprising a housing 1, with two side blocks 2 fixedly connected to both the left and right sides of the housing 1, providing stable support for the side blocks 2. Bolts 3 are detachably connected to the inner walls of the side blocks 2, used to fix the housing 1 to the ground. A top cover 4 is rotatably connected to the top of the housing 1. Both the housing 1 and the top cover 4 are made of polyethylene, providing good moisture protection even when the device is placed on the ground. Multiple transformers 5 are fixedly connected to the bottom of the inner wall of the housing 1, used to connect external equipment to change the magnitude of AC voltage and current.

[0034] Multiple tube coils 6 are fixedly connected to the front end of the housing 1. The housing 1 here provides stable support for the tube coils 6. A connecting wire 7 is fixedly connected to the inner wall of the transformer 5. The outside of the connecting wire 7 is in contact with the inner wall of the tube coils 6. The connecting wire 7 here is used to connect external devices to the transformer 5.

[0035] Reference Figures 2 to 4 The front end of the top cover 4 is fixedly connected to a locking assembly for connecting the housing 1 and the top cover 4. The locking assembly includes a locking plate 8, the rear end of which is fixedly connected to the front end of the top cover 4. The top cover 4 here provides support for the locking plate 8. The bottom end of the locking plate 8 is fixedly connected to a locking block 9. The front end of the housing 1 is fixedly connected to a locking plate 10. After the locking plates 8 and 10 are fixed, they can ensure the closed state between the housing 1 and the top cover 4. The bottom end of the locking plate 8 and the locking plate 10 are... The tops of the two parts are in contact with each other. The outer side of the locking block 9 is slidably connected to the inner wall of the second locking plate 10. The locking block 9 here is the key to closing the top cover 4 and the shell 1. The inner wall of the second locking plate 10 is slidably connected to two sliding pillars 11. The second locking plate 10 here provides a stable sliding space for the sliding pillars 11. The adjacent side of the two sliding pillars 11 is fixedly connected to the limiting block 12. The outer side of the limiting block 12 is slidably connected to the inner wall of the second locking plate 10. The limiting block 12 here limits the maximum sliding range of the sliding pillar 11.

[0036] Two locking balls 13 are fixedly connected to adjacent sides of the two limiting blocks 12. The locking balls 13 and the locking blocks 9 are in an engaging relationship. When it is necessary to open the top cover 4, simply rotate the top cover 4 so that the locking blocks 9 collide with the locking balls 13, causing them to retract into the inner wall of the second locking plate 10. The locking balls 13 are externally slidably connected to the inner wall of the second locking plate 10. A spring 14 is sleeved on the outside of the sliding column 11. One end of the spring 14 is fixedly connected to one side of the inner wall of the second locking plate 10, and the other end of the spring 14 is fixedly connected to one side of the limiting block 12. Here, the spring 14 provides a reaction force for the locking balls 13, so that they can block the front end of the locking block 9, thus playing a locking role.

[0037] Reference Figure 2 and Figure 5 A rubber ring 15 is fixedly connected to the inner wall of the housing 1, and a rubber block 16 is slidably connected to the inner wall of the rubber ring 15. The rubber ring 15 provides a stable sliding space for the rubber block 16. A sleeve plate 17 is fixedly connected to the bottom end of the top cover 4. The bottom end of the sleeve plate 17 contacts the top end of the rubber ring 15. When the top cover 4 and the housing 1 are closed, the sleeve plate 17 and the rubber ring 15 are in close contact, effectively preventing condensation from entering the interior of the housing 1 from the connection between the top cover 4 and the housing 1 and causing damage to the transformer 5.

[0038] A limiting strip 18 is fixedly connected to the bottom end of the rubber block 16. The outer side of the limiting strip 18 is slidably connected to the inner wall of the rubber ring 15. The limiting strip 18 here restricts the sliding range of the rubber block 16. A second spring 19 is fixedly connected to one side of the limiting strip 18. The other end of the second spring 19 is fixedly connected to one side of the inner wall of the rubber ring 15. The second spring 19 here is in a compressed state, which makes the rubber block 16 and the sleeve plate 17 fit more tightly, further improving the moisture-proof and anti-condensation effect.

[0039] Working principle: First, the transformer 5 here can be connected to external equipment via the connecting line 7, thereby controlling the magnitude of AC voltage and current. The coil 6 here acts as a constraint for the connecting line 7. When the transformer 5 needs to be repaired, the top cover 4 can be opened first. The top cover 4 can be rotated directly, causing the locking block 9 to press the two locking balls 13, causing them to retract into the interior of the second locking plate 10, thus opening the top cover 4. After that, the top cover 4 can be directly fastened to the top of the housing 1. After the locking block 9 presses the locking balls 13, the locking balls 13 will be reset under the force of the first spring 14, thus completing the engagement with the locking block 9.

[0040] At the same time, after closing, the rubber block 16 will be tightly attached to the inner wall of the sleeve plate 17 under the action of the spring 19, thereby effectively preventing condensation from entering the interior of the housing 1 from the connection between the housing 1 and the top cover 4, thus damaging the transformer 5. The housing 1 and the top cover 4 are both made of polyethylene, which has a good moisture-proof effect even when the device is placed on the ground. The two work together to achieve the purpose of effective moisture-proofing and condensation prevention, thereby improving the service life of the transformer 5.

[0041] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. 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.
