Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of transformers, in particular to a high-heat-dissipation waterproof transformer. BACKGROUND

[0002] Transformers can be divided into many kinds of transformers, among which the box-type transformer is a compact power distribution device that combines high-voltage switchgear, distribution transformers and low-voltage distribution devices in one box, and is widely used in residential areas, commercial centers, industrial parks, urban road lighting and other places.

[0003] When an alternating current power source is connected to the primary coil of the transformer, an alternating current will be generated in the primary coil. This alternating current will generate an alternating magnetic field in the core. Since the core is closed, the alternating magnetic field can pass through the core and reach the secondary coil. According to the law of electromagnetic induction, when the magnetic flux passing through the secondary coil changes, an induced electromotive force will be generated in the secondary coil. If the number of turns of the secondary coil is different from that of the primary coil, the output voltage will also change accordingly. When the number of turns of the secondary coil is greater than that of the primary coil, the output voltage rises, which is called a step-up transformer. Conversely, when the number of turns of the secondary coil is less than that of the primary coil, the output voltage decreases, which is called a step-down transformer.

[0004] The box-type transformer needs to be poured with a cement base to ensure flatness. When encountering continuous heavy rainfall, the accumulated water on the ground will gradually accumulate to a certain height. Although the existing box-type transformer itself has a certain waterproof function, the box-type transformer is assembled by metal splicing, so there will be gaps at the splicing part, and the box-type transformer needs a heat dissipation port. Therefore, when the accumulated water reaches a certain height and spreads to the heat dissipation port and gap of the box-type transformer, the water will enter the inside of the box-type transformer along the heat dissipation port and gap of the box-type transformer. Water is a good conductor, and when a large amount of water enters the inside of the box-type transformer, it will cause a short circuit between the live parts, causing a large instantaneous current, damaging electrical equipment, and causing tripping and power failure. For example, water causes a short circuit between the high-voltage winding and the low-voltage winding, instantaneously generating a large amount of heat and arc, thereby causing a large-scale fire.

[0005] Therefore, a high-heat-dissipation waterproof transformer is proposed. SUMMARY

[0045] The protective assembly further comprises a fixed track 15 fixedly connected to the bottom of the rain shield 10 in a symmetrical manner, the fixed track 15 is not less than two, the inside of each fixed track 15 is slidably connected with a sliding rod one 16 in a symmetrical manner, the top of each connecting rod two 14 is rotatably connected with the sliding rod one 16, and the sliding rod one 16 is not less than four, and one end of each sliding rod one 16 away from the connecting rod two 14 is fixedly connected with a protective rod 17.

[0046] The inside of the rain shield 10 is provided with a warning assembly for reminding pedestrians and vehicles that there is danger here, the warning assembly comprises a groove one 18 symmetrically formed in the inside of the rain shield 10, the groove one 18 is located on the movement path of the connecting rod one 9, and the groove one 18 is not less than two, the inside of the rain shield 10 is symmetrically formed with a groove two 19, the groove one 18 and the groove two 19 are cross-shaped, the groove two 19 is not less than two, the inside of each groove two 19 is slidably connected with a sliding rod two 20, one end of each sliding rod two 20 away from the groove two 19 is fixedly connected with a danger warning plate 21, the end of the sliding rod two 20 away from the danger warning plate 21 is provided as an inclined surface, the top of the connecting rod one 9 is matched with the inclined surface of the sliding rod two 20, the bottom of each sliding rod two 20 is fixedly connected with a fixed plate two 22, and the fixed plate two 22 and the rain shield 10 are fixedly connected with a spring 23.

[0047] The warning assembly further comprises a groove three 24 symmetrically formed in the side wall of the sliding rod two 20, the groove three 24 is not less than four, the inside of each groove three 24 is rotatably connected with a rotating strip 25, the rotating strip 25 and the outer side of the protective rod 17 are both wrapped with red and yellow alternating stickers, thereby playing a role of being able to quickly attract attention, a torsional spring 26 is fixedly connected between each groove three 24 and the rotating strip 25, and the torsional spring 26 is not less than eight.

[0048] The working principle of the above implementation is as follows:

[0049] The initialization steps are as follows:

[0050] The spring 23 is not stretched, and the torsion spring 26 is in a tightened state.

[0051] The working steps of the trigger assembly are as follows:

[0052] The working steps of the trigger assembly are as follows:

[0053] The box-type transformer is usually installed on the ground. When continuous heavy rainfall causes a certain height of accumulated water on the ground, the floating ball 7 floats on the surface of the accumulated water by its own floating force. When the height of the accumulated water causes the floating ball 7 to slide vertically upward in the clamping groove of the cement base 1, the floating ball 7 abuts against and presses the electrical switch 8, so that the filled compressed nitrogen gas in the air bag 6 expands rapidly.

[0054] Through the setting of the trigger assembly, when a certain height of accumulated water is encountered on the ground, the air bag 6 can be triggered to expand at the first time, so that the bottom of the box-type transformer example 2 can be avoided from being affected by the water at the first time.

[0055] The working steps of the waterproof assembly are as follows:

[0056] When the air bag 6 starts to expand, the air bag 6 expands and abuts against the top of the limiting plate 4, so that the air bag 6 pushes the limiting plate 4 to slide vertically upward in the sliding groove of the fixed frame 3. Therefore, the air bag 6 is guided to expand vertically upward by the limiting plate 4, and the air bag 6 also wraps the bottom of the box-type transformer example 2 around. The limiting plate 4 drives the limiting rod 5 to move synchronously. When the limiting rod 5 moves to the bottom of the fixed frame 3, the limiting rod 5 abuts against and clamps the fixed frame 3, so that the limiting rod 5 limits the continuous vertical upward sliding of the limiting plate 4, avoiding the air bag 6 pushing the limiting plate 4 to slide out of the sliding groove of the fixed frame 3.

[0057] Through the cooperation of the trigger assembly and the waterproof assembly, the expansion of the air bag 6 can completely wrap the bottom of the box-type transformer example 2, avoiding the situation that the heat dissipation channel of the bottom of the box-type transformer example 2 enters the water. The air bag 6 also wraps the bottom of the box-type transformer example 2 around, avoiding the situation that the water enters the inside of the box-type transformer example 2 from the gap at the bottom of the box-type transformer example 2. Therefore, the situation that the box-type transformer example 2 is affected by the water and appears short circuit is avoided, and the situation that the debris is hit to the box-type transformer example 2 with the water flow due to the excessive water is avoided, so that the damage of the box-type transformer example 2 caused by the impact is avoided.

[0058] The working steps of the protection assembly are as follows:

[0059] As described above, when the limiting plate 4 moves vertically upward, the limiting plate 4 drives the connecting rod one 9 to move vertically upward and close to the fixed track 15, the vertical upward movement of the connecting rod one 9 drives the fixed plate one 11 to move synchronously, the fixed plate one 11 drives the rotating column 12 to move synchronously, the rotating column 12 continuously moves close to the fixed track 15, so the vertical distance between the rotating column 12 and the fixed track 15 continuously decreases, at the same time, the limiting column 13 and the connecting rod two 14 close to the side wall of the connecting rod one 9 are in contact, which can limit the reverse rotation of the connecting rod two 14, so the connecting rod two 14 starts to rotate away from the limiting column 13 with the rotating column 12 as the axis, so the horizontal length of the connecting rod two 14 becomes larger and larger, so the connecting rod two 14 drives the sliding rod one 16 to slide on the fixed track 15 away from the groove one 18, so the two sliding rod one 16 located in the same fixed track 15 moves away from each other, so the two sliding rod one 16 located in the same fixed track 15 drives the protection rod 17 to move away from the rain shield 10.

[0060] Through the mutual cooperation of the triggering assembly and the protection assembly, it can remind pedestrians and vehicles to avoid, avoid approaching due to poor visibility or unfamiliarity with the environment, and reduce the occurrence of electric shock and other dangerous accidents.

[0061] The working steps of the warning assembly are as follows:

[0062] As described above, when the connecting rod one 9 moves vertically upward, because the groove one 18 is located on the movement path of the connecting rod one 9, when the connecting rod one 9 moves into the groove one 18, the top of the connecting rod one 9 and the inclined surface of the sliding rod two 20 are in contact, so the top of the connecting rod one 9 drives the sliding rod two 20 to slide in the groove two 19 away from the connecting rod one 9, the sliding rod two 20 drives the fixed plate two 22 to move synchronously, the fixed plate two 22 starts to stretch the spring 23, the sliding rod two 20 drives the danger warning board 21 to extend away from the rain shield 10, at the same time, when the groove three 24 on the sliding rod two 20 completely extends out of the groove two 19, the torsional spring 26 in the tightened state makes the rotating strip 25 rotate away from the sliding rod two 20 with the connection between the rotating strip 25 and the sliding rod two 20 as the axis through the elastic expansion force, so the rotating strip 25 on both sides of the sliding rod two 20 unfolds away from the sliding rod two 20, because the red and yellow alternating stickers are wrapped outside the rotating strip 25, so the extension of the rotating strip 25 and the danger warning board 21 can play a reminding and warning role.

[0063] The mutual cooperation of the protection assembly and the warning assembly can obviously mark the position of the box-type transformer example 2, and the danger warning board 21 can obviously inform the surrounding people that this is a dangerous area with electric charge, and the rescue personnel can more easily find and determine the position of the box-type transformer through the protection rod 17, the danger warning board 21 and the rotating strip 25, so as to take corresponding measures to protect the box-type transformer example 2.

[0064] When the heavy rainfall weather ends and the ground water subsides, the fixed plate two 22 is pulled to the direction of approaching the rain shield 10 by the elastic contraction force of the stretched spring 23, so that the sliding rod two 20 is slid to the direction of approaching the connecting rod one 9 in the inside of the groove two 19, and the rotating strip 25 is pressed by the groove two 19 to rotate in the direction of approaching the sliding rod two 20, so as to make the torsion spring 26 in the tightened state again, and the ground water subsides and the floating ball 7 no longer touches the electric switch 8, so that the air bag 6 no longer continuously expands, and the inclined surface of the sliding rod two 20 pushes the connecting rod one 9 to move vertically downward, and the above working steps are reversed, so that the protection rod 17 returns to the position directly below the rain shield 10 again.
