Description

Technical Field

[0001] The invention relates to the technical field of transformers, in particular to a transformer with a lightning protection function. Background Art

[0002] Transformers are basic equipment for power transmission and distribution and are generally installed outdoors. Transformers are devices that use the principle of electromagnetic induction to change AC voltage. Their main functions include voltage conversion, current conversion, impedance conversion, isolation and voltage stabilization (magnetic saturation transformer). Since transformers are placed outdoors and are generally placed at high altitudes on utility poles, they are relatively more susceptible to electric shocks during thunderstorms, and thus require lightning protection structures for lightning protection.

[0003] Existing transformers with lightning protection structures often collect rainwater and use the circulation of rainwater to cool and dissipate heat for the transformer. However, after the rainwater absorbs heat during circulation, its temperature rises until it is consistent with the heating temperature of the transformer, thus rendering the cooling and heat dissipation effect of the rainwater ineffective.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a transformer with lightning protection function is proposed. Summary of the invention

[0007] Furthermore, an insulating protective net is provided on the surface of the insulating board frame, and the rainwater collecting pipe is located inside the insulating protective net.

[0008] Furthermore, the sheet-like pipe has a U-shaped structure, and the sheet-like pipe is attached to both sides of the heat sink.

[0009] Furthermore, the collecting pipe is connected with the water tank after passing through the cooling box, and the part of the collecting pipe located inside the cooling box has a spiral structure.

[0010] Furthermore, water control components are provided between the cooling boxes and at the connection points between the cooling boxes on the top layer and the rainwater collecting pipes. The water control components include a connecting pipe and a wide-mouthed pipe. The bottom of the connecting pipe is connected to the wide-mouthed pipe.

[0011] Furthermore, the inner diameter of the wide-mouthed tube is larger than the inner diameter of the connecting tube, and the wide-mouthed tube and the collecting tube are not in contact with each other.

[0012] Furthermore, the water control component further comprises a water outlet hole and a float ball, the water outlet holes are evenly opened on the surface of the wide-mouthed tube, and the float ball is arranged inside the wide-mouthed tube.

[0013] Furthermore, a ventilation cavity is provided at the bottom of the inner wall of the cooling box, and a heat-insulating material is used in the water storage cavity inside the cooling box.

[0014] Furthermore, a rotating motor is fixed on the front surface of the cooling box, and an output end of the rotating motor is connected to a rotating shovel plate inside the cooling box.

[0015] Furthermore, an auxiliary ventilation component is provided at the bottom of the transformer body, and the auxiliary ventilation component includes an exhaust pump and a heat exhaust pipe. A heat exhaust pipe is provided on the right side of the exhaust pump, and the heat exhaust pipe is communicated with the ventilation cavity.

[0016] The present invention provides a transformer with lightning protection function, which has the following beneficial effects:

[0017] 1. The transformer with lightning protection function plays a role of lightning protection through the setting of insulating plate frame and lightning arrester. In rainy weather, rainwater is collected and circulated around the transformer body to cool and dissipate heat. The part of the collecting pipe located inside the cooling box is in a spiral structure to extend the flow time of the rainwater after absorbing heat in the cooling box, so that the rainwater after absorbing heat is fully cooled by the saltpeter liquid to ensure that the cooling effect on the transformer body will not be reduced. There are multiple cooling boxes and they are interconnected, and the collecting pipe passes through each cooling box in turn, so that the rainwater after absorbing heat can be cooled multiple times to further improve the cooling effect.

[0018] 2. The transformer with lightning protection function has a water level sensor and a temperature sensor inside the cooling box, and the rotating shovel plate divides each cooling box into a water storage chamber and a cavity from top to bottom. The back of the cavity is connected to an automatic feeding mechanism. The automatic feeding mechanism feeds saltpeter into the cavity in an appropriate amount according to the temperature and water level. The rotating motor drives the rotating shovel plate to rotate, so that the added saltpeter material can be fully mixed with rainwater to accelerate dissolution. In order to prevent the rainwater from completely evaporating, the water tank and the cooling box can be connected to the water pipe to replenish water in real time based on the water level change, so that the cooling measures for the transformer body can be effective for a long time.

[0019] 3. The transformer with lightning protection function can extract the hot air inside the transformer body through the vacuum pump and discharge it into the ventilation cavity along the heat exhaust pipe. The ventilation cavity uses heat-conducting materials to absorb heat and heat the remaining water in the cavity to evaporate it, leaving crystals, namely saltpeter. Therefore, the saltpeter is manually recovered regularly and re-injected into the automatic feeding mechanism, thereby realizing the recycling of saltpeter materials. Regular saltpeter recovery can be carried out simultaneously with regular maintenance to reduce the labor burden. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention but are not intended to limit the scope of the present invention.

[0028] like Figure 1-Figure 5 As shown, the present invention provides a technical solution: a transformer with lightning protection function, comprising a transformer body 1 and a rainwater collection and utilization component 4, an insulating plate frame 2 is arranged on the top of the transformer body 1, and a lightning arrester 3 is arranged on the top of the insulating plate frame 2, heat sinks 5 are arranged on the front and rear sides of the transformer body 1, and microporous dehumidification plates 6 are embedded between the heat sinks 5 and the front and rear surfaces of the transformer body 1, the rainwater collection and utilization component 4 is fixed around the bottom of the insulating plate frame 2, the rainwater collection and utilization component 4 comprises a rainwater collection pipe 401, a water tank 402, a water distribution pipe 403, a sheet pipe 404, a collection pipe 405, a cooling box 406 and saltpeter liquid 407, the end of the rainwater collection pipe 401 is connected to the water tank 402, and a pump body is arranged inside the water tank 402, and the water tank 40 2 is connected with a water distribution pipe 403 on the upper side, and sheet pipes 404 are evenly distributed at the bottom of the water distribution pipe 403, and a collecting pipe 405 is connected to one end of the sheet pipe 404 away from the water distribution pipe 403, a cooling box 406 is distributed on the right side of the transformer body 1, and the top of the cooling box 406 is connected with the rain collecting pipe 401, and saltpeter liquid 407 is arranged inside the cooling box 406, an insulating protection net 7 is arranged on the surface of the insulating plate frame 2, and the rain collecting pipe 401 is located on the inner side of the insulating protection net 7, the sheet pipe 404 is in a U-shaped structure, and the sheet pipe 404 is attached to both sides of the heat sink 5, the collecting pipe 405 passes through the cooling box 406 and is connected to the water tank 402, and the part of the collecting pipe 405 located inside the cooling box 406 is in a spiral structure;

[0029] The specific operation is as follows: the insulating plate frame 2 and the lightning arrester 3 are provided to provide lightning protection, and in rainy weather, rainwater passes through the insulating protection net 7 and falls on the surface of the insulating plate frame 2, and slides along the surface of the insulating plate frame 2 to the rainwater collecting pipe 401, and finally the rainwater enters the water tank 402 for storage, wherein the insulating protection net 7 can play a role in removing impurities, preventing impurities from entering the water tank 402;

[0030] The transformer body 1 generates heat when working. In the presence of wind, the outside air passes through the microporous dehumidification plates 6 between the heat sinks 5 to be dehumidified and then passes through the transformer body 1 to achieve heat dissipation. The heat sink 5 will extract the heat inside the transformer body 1. The pump body in the water tank 402 allows rainwater to flow along the water distribution pipe 403, the sheet pipe 404, and the collection pipe 405 and finally return to the inside of the water tank 402, so as to realize the circulation of rainwater around the transformer body 1, thereby enhancing the heat dissipation effect. The sheet pipe 404 is attached to both sides of the heat sink 5 to enhance the cooling effect of the heat extracted from the heat sink 5, and the air outside the microporous dehumidification plate 6 is pre-cooled, so that the temperature of the air passing through the inside of the transformer body 1 is relatively low to cool the inside thereof.

[0031] The cooling boxes 406 are interconnected, and the top cooling box 406 is connected to the rainwater collecting pipe 401. When the rainwater is collected by the rainwater collecting pipe 401, part of the rainwater will enter the cooling box 406. The rainwater is mixed with the saltpeter in the cooling box 406 to form a saltpeter liquid 407, wherein the saltpeter can be replaced by pure ammonium nitrate, thereby cooling the inside of the cooling box 406. The part of the collecting pipe 405 located inside the cooling box 406 is in a spiral structure to extend the flow time of the rainwater after absorbing heat in the cooling box 406, so that the rainwater after absorbing heat is fully cooled to ensure that the cooling effect on the transformer body 1 will not be reduced. The cooling boxes 406 are provided with a plurality of them and are interconnected, and the collecting pipe 405 passes through each cooling box 406 in turn, so that the rainwater after absorbing heat can be cooled multiple times to further improve the cooling effect.

[0032] like Figure 1 , Figure 5-Figure 6 As shown, a water control component 8 is provided between the cooling boxes 406 and at the connection between the cooling box 406 on the top layer and the rainwater collecting pipe 401. The water control component 8 includes a connecting pipe 801 and a wide-mouthed pipe 802. The bottom of the connecting pipe 801 is connected with the wide-mouthed pipe 802. The inner diameter of the wide-mouthed pipe 802 is larger than the inner diameter of the connecting pipe 801, and the wide-mouthed pipe 802 and the collecting pipe 405 do not contact each other. The water control component 8 also includes a water outlet 803 and a floating ball 804. The surface of the wide-mouthed pipe 802 is evenly provided with water outlet holes 803, and the wide-mouthed pipe 802 is provided with a floating ball 804 inside.

[0033] The specific operation is as follows: rainwater passes through the rainwater collecting pipe 401, the connecting pipe 801, the wide-mouthed pipe 802 and the water outlet 803 on its surface and enters into each cooling box 406 in turn. As the water level inside the cooling box 406 rises, the float 804 floats along the inner wall of the wide-mouthed pipe 802 with the water level until it rests against the top opening of the wide-mouthed pipe 802. In this way, the water level inside each cooling box 406 is controlled at a suitable position from bottom to top to avoid uneven water distribution leading to insufficient dissolution of saltpeter. A filter plate is provided on the top of the connecting pipe 801, which only allows water to pass through, while the saltpeter material is blocked.

[0034] like Figure 1 , Figure 5 As shown, a rotating motor 10 is fixed to the front surface of the cooling box 406, and the output end of the rotating motor 10 is connected to a rotating shovel plate 11 inside the cooling box 406;

[0035] The specific operation is as follows: a water level sensor and a temperature sensor are arranged inside the cooling box 406, and the rotating shovel plate 11 divides each cooling box 406 into a water storage cavity and a cavity from top to bottom. The back of the cavity is connected to an automatic feeding mechanism, and the automatic feeding mechanism feeds an appropriate amount of saltpeter into the cavity according to the temperature and water level. The rotating motor 10 drives the rotating shovel plate 11 to rotate, so that the added saltpeter material can be fully mixed with rainwater to accelerate dissolution, and in order to prevent the rainwater from completely evaporating, the water tank 402 and the cooling box 406 can be connected to the water pipe to replenish water in real time based on the water level change, so that the cooling measures for the transformer body 1 can be effective for a long time.

[0036] like Figure 1 , Figure 5 As shown, a ventilation cavity 9 is provided at the bottom of the inner wall of the cooling box 406, and the water storage cavity inside the cooling box 406 is made of heat-insulating material. An auxiliary ventilation component 12 is provided at the bottom of the transformer body 1. The auxiliary ventilation component 12 includes an air extraction pump 1201 and a heat exhaust pipe 1202. A heat exhaust pipe 1202 is provided on the right side of the air extraction pump 1201, and the heat exhaust pipe 1202 is connected to the ventilation cavity 9;

[0037] The specific operation is as follows: since the amount of saltpeter is limited, after the saltpeter is consumed, the hot air inside the transformer body 1 can be extracted through the vacuum pump 1201 and discharged into the ventilation cavity 9 along the heat exhaust pipe 1202. The ventilation cavity 9 uses a heat-conducting material to absorb heat and heat the remaining water in the cavity to evaporate it, thereby leaving behind a crystal, which is saltpeter. Therefore, the saltpeter is manually recovered regularly and re-injected into the automatic feeding mechanism, thereby realizing the recycling of the saltpeter material. Regular recovery of saltpeter can be carried out simultaneously with regular maintenance.

[0038] In summary, if Figure 1-Figure 6As shown, when the transformer with lightning protection function is used, the insulating plate frame 2 and the lightning arrester 3 are first provided to provide lightning protection, and in rainy weather, rainwater passes through the insulating protection net 7 and falls on the surface of the insulating plate frame 2, and slides along the surface of the insulating plate frame 2 to the rainwater collecting pipe 401, and finally the rainwater enters the water tank 402 for storage, wherein the insulating protection net 7 can play a role in removing impurities, preventing impurities from entering the water tank 402;

[0039] The transformer body 1 generates heat when working. In the presence of wind, the outside air passes through the microporous dehumidification plates 6 between the heat sinks 5 to be dehumidified and then passes through the transformer body 1 to achieve heat dissipation. The heat sink 5 will extract the heat inside the transformer body 1. The pump body in the water tank 402 allows rainwater to flow along the water distribution pipe 403, the sheet pipe 404, and the collection pipe 405 and finally return to the inside of the water tank 402, so as to realize the circulation of rainwater around the transformer body 1, thereby enhancing the heat dissipation effect. The sheet pipe 404 is attached to both sides of the heat sink 5 to enhance the cooling effect of the heat extracted from the heat sink 5, and the air outside the microporous dehumidification plate 6 is pre-cooled, so that the temperature of the air passing through the inside of the transformer body 1 is relatively low to cool the inside thereof.

[0040] The cooling boxes 406 are interconnected, and the cooling box 406 on the top layer is connected to the rainwater collecting pipe 401. When the rainwater is collected by the rainwater collecting pipe 401, part of the rainwater will enter the cooling box 406. The rainwater is mixed with the saltpeter in the cooling box 406 to form a saltpeter liquid 407, wherein the saltpeter can be replaced by pure ammonium nitrate, thereby cooling the inside of the cooling box 406. The part of the manifold 405 located inside the cooling box 406 is in a spiral structure to extend the flow time of the rainwater after absorbing heat in the cooling box 406, so that the rainwater after absorbing heat is fully cooled to ensure that the cooling effect on the transformer body 1 will not be reduced. The cooling boxes 406 are provided with a plurality of them and are interconnected, and the manifold 405 passes through each cooling box 406 in sequence, so that the rainwater after absorbing heat can be cooled multiple times to further improve the cooling effect.

[0041] Rainwater passes through the rainwater collecting pipe 401, the connecting pipe 801, the wide-mouthed pipe 802 and the water outlet 803 on its surface and enters the cooling boxes 406 in sequence. As the water level in the cooling boxes 406 rises, the float 804 floats along the inner wall of the wide-mouthed pipe 802 until it abuts against the top opening of the wide-mouthed pipe 802, thereby controlling the water level in each cooling box 406 in sequence from bottom to top at a suitable position to avoid uneven water distribution leading to insufficient dissolution of saltpeter. A filter plate is provided on the top of the connecting pipe 801 to only allow water to pass through, while the saltpeter is blocked.

[0042] The cooling box 406 is provided with a water level sensor and a temperature sensor, and the rotating shovel plate 11 divides each cooling box 406 into a water storage cavity and a cavity from top to bottom. The back of the cavity is connected to an automatic feeding mechanism, and the automatic feeding mechanism feeds saltpeter into the cavity in an appropriate amount according to the temperature and water level. The rotating motor 10 drives the rotating shovel plate 11 to rotate, so that the added saltpeter material can be fully mixed with rainwater to accelerate dissolution. In order to prevent the rainwater from completely evaporating, the water tank 402 and the cooling box 406 can be connected to the water pipe to replenish water in real time based on the water level change, so that the cooling measures for the transformer body 1 can be effective for a long time;

[0043] Since the amount of saltpeter is limited, after the saltpeter is consumed, the hot air inside the transformer body 1 can be extracted through the vacuum pump 1201 and discharged into the ventilation cavity 9 along the heat exhaust pipe 1202. The ventilation cavity 9 uses heat-conducting materials to absorb heat and heat the remaining water in the cavity to evaporate it, thereby leaving crystals, which are saltpeter. Therefore, the saltpeter is manually recovered regularly and re-injected into the automatic feeding mechanism, thereby realizing the recycling of saltpeter materials. Regular recovery of saltpeter can be carried out simultaneously with regular maintenance.

Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
