Description

Technical Field

[0001] The present invention relates to the technical field of transformers, and in particular to an outdoor explosion-proof power control transformer. Background Art

[0002] A transformer is a device that uses electromagnetic induction to change the voltage level of an alternating current (AC). It primarily consists of two sets of coils—a primary and a secondary—an iron or magnetic core, and insulation. Outdoor explosion-proof power control transformers, particularly those found in transformer substations, feature a special explosion-proof structure to prevent internal sparks or high temperatures from triggering an explosion.

[0003] Prior art includes an invention with publication number CN112802663B, which discloses an outdoor transformer comprising a transformer body, with a plurality of heat sinks mounted on the outside of the transformer body. A reinforcing rib is fixed to the side of the heat sink away from the transformer body. In this outdoor transformer, when leaves are present on top of the reinforcing ribs, the heat dissipation effect of the heat sink covered by the leaves deteriorates, and the temperature of the portion of the drive cavity in the reinforcing rib located at the heat sink is higher. Under the action of the air pressure difference on both sides of the heat-insulating drive block, the heat-insulating drive block moves and, through the drive mechanism and transmission mechanism, causes the cleaning plate to rise. The rising cleaning plate is on the side of the heat sink with the higher temperature. As the cleaning plate rises, it pushes the leaves upward, causing them to move. During this movement, the leaves slide on the heat sink, thereby reducing the stability of the leaves and causing them to fall off the heat sink, preventing the leaves from affecting the heat dissipation of the transformer.

[0004] It was found in the transformer substation that the protection performance of the existing outdoor power control transformer is average. Due to long-term outdoor operation, the sunlight exposure will cause the temperature of the metal transformer to rise. At the same time, as the load increases, the loss will also increase accordingly, resulting in increased heat generation, which can easily cause explosion damage inside the entire transformer.

[0036] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0038] Example 1, as Figure 1-2As shown, the present invention provides an outdoor explosion-proof power control transformer, including a mounting frame 1, a transformer body 2, an electrical connection frame 4 and a winding body 9. The transformer body 2 is usually arranged and installed on the outdoor mounting frame 1, and the transformer body 2 is mainly operated by the internal electrical components to generate the electromagnetic induction principle to change the AC voltage level. At the same time, the voltage conversion ratio of the transformer body 2 is determined by the turns ratio of the winding in the transformer body 2, and the cable docking operation is performed by the electrical connection frame 4 installed on the surface of the top plate 3 of the upper end of the transformer body 2. During the long-term operation of the transformer body 2, heat is generated due to the iron loss and copper loss in the transformer body 2. At the same time, as the load increases, the loss will also increase accordingly, resulting in an increase in the heat generated. The internal temperature of the transformer body 2 will be too high, or even explode. In this process, in order to avoid burning when the temperature is too high, the flame retardant placed in the carrier frame 1001 is used for protection. The cylinder 1004 drives the push rod to move, pushing the flame retardant in the carrying frame 1001 into the guide frame 1002, and at the same time, the seepage holes 1012 opened on the lower surface of the guide frame 1002 are scattered. At the same time, it can also be protected by the heat dissipation and explosion-proof mechanism 5 set on one side of the base 8 on the lower surface of the transformer body 2. The water pump 502, water inlet pipe 504, water outlet pipe 505 and heat dissipation plate 511 in the heat dissipation and explosion-proof mechanism 5 are used in combination to perform heat dissipation and cooling operations on the inside of the transformer body 2. When installing the entire outdoor transformer body 2, the hoisting mechanism 7 on both sides of the top plate 3 surface can be used for assistance. The lifting ring 75 can be used to effectively and conveniently lift the entire transformer body 2 into position, and then the transformer body 2 is placed on the surface of the mounting frame 1, and the mounting mechanism 6 is used for auxiliary regulation. The driving rod 62 in the mounting mechanism 6 drives the extrusion blocks 64 on both sides of the mounting plate 61 to be squeezed and fixed with the side wall of the mounting frame 1, so as to quickly and conveniently perform fixed limit operations with the mounting frame 1.

[0039] The specific settings and functions of the heat dissipation and explosion-proof mechanism 5, the installation mechanism 6, the hanging mechanism 7 and the protection mechanism 10 are described in detail below.

The surface of the connecting frame 501 is fixedly connected to a water tank 503, which is used to provide water for the water pump 502. The bottom end of the water tank 503 is fixedly connected to a conduit 508, which is used to conveniently transport water to the water pump 502. The bottom end of the conduit 508 is fixedly connected to the connecting pipe 506. The arc surface of the conduit 508 is installed with a solenoid valve 507. The solenoid valve 507 can be used to regulate the delivery volume of the conduit 508. The ends of the water inlet pipe 504 and the water outlet pipe 505 close to each other are fixedly connected to the same docking pipe 517. The cross-section of the docking pipe 517 is "S" shaped. The heat absorbed by the surface of the heat sink 511 can be absorbed and dissipated through the docking pipe 517. The docking pipe 517 is located inside the transformer body 2 The inner wall of the transformer body 2 is fixedly connected with a protective frame 509, which can further protect the transformer body 2 to avoid the risk of explosion and splashing. The bottom surface of the protective frame 509 is fixedly connected with the water inlet pipe 504 and the water outlet pipe 505. The side wall of the protective frame 509 is fixedly connected with a connecting rod 510. The cross-section of the connecting rod 510 is convex. The connecting rod 510 can be used to slide and limit the position of the heat sink 511. The upper surface of the heat sink 511 is provided with a through hole 512. The through hole 512 can be used to slide along the surface of the connecting rod 510.

The cross section of the plate 511 is cross-shaped. The heat dissipation plate 511 is an aluminum plate. An inlay groove 518 is provided on the surface of the heat dissipation plate 511. With the help of the inlay groove 518, it is convenient and quick to penetrate and limit the connection with the docking tube 517.

The surface of the connecting plate 515 slides through a moving rod 514. The bottom end of the moving rod 514 is fixedly connected to the limiting frame 513, so that the limiting frame 513 can slide up and down along the connecting plate 515 with the help of the moving rod 514, which is convenient for clamping and fixing the position of the heat dissipation plate 511. The cross section of the lower surface of the limiting frame 513 is "U"-shaped. The inner wall of the limiting frame 513 is plugged into the upper surface of the heat dissipation plate 511.The arc surface of the movable rod 514 is covered with a spring 516. The tensile force generated by the spring 516 is used to better squeeze and fix the limit frame 513. The two ends of the spring 516 are respectively fixedly connected to the movable rod 514 and the connecting plate 515. The protective frame 509 is a cast iron frame. Cast iron has excellent mechanical strength and corrosion resistance, making it suitable for harsh environments and facilitating better protection of the transformer body 2. The cross-section of the protective frame 509 is rectangular, and the cross-sectional dimensions of the protective frame 509 are adapted to the inner wall dimensions of the transformer body 2.

[0041] When the transformer body 2 is operated for a long time, the interior of the transformer body 2 will be loaded due to loss, thereby generating heat and causing the temperature to rise. At this time, in order to avoid explosion caused by temperature changes inside the transformer body 2, the heat sink 511 in the heat dissipation and explosion-proof mechanism 5 can be used for auxiliary operation. The water in the water storage tank 503 is circulated by the water pump 502 through the water inlet pipe 504, the water outlet pipe 505 and the docking pipe 517, so that the heat sink 511 on one side of the protective frame 509 inside the transformer body 2 absorbs heat, performs a cooling operation, and effectively and conveniently reduces the temperature of the inner wall of the transformer body 2 for protection.

The side of the two extrusion blocks 64 close to each other abuts against the side wall of the mounting frame 1, and the position of the entire transformer body 2 is fixed by the extrusion block 64. One side of the inner wall of the mounting plate 61 is fixedly connected to the limiting rod 63. The limiting rod 6 The arc surfaces at both ends of 3 slide through the surface of the extrusion block 64. In order to prevent the sliding position of the extrusion block 64 from being offset, the limit rod 63 has connecting holes 69 on both sides of the base 8. The connecting hole 69 is used to facilitate the sliding fixation of the positioning rod 68. The inner wall of the connecting hole 69 is movably connected with the positioning rod 68.

The carrier frame 1001 is away from the gas A fan module 1007 is fixedly connected to one side of the cylinder 1004, and a guide tube 1013 is fixedly connected to the lower surface of the fan module 1007. The wind generated by the fan module 1007 is introduced into the guide tube 1013. One end of the guide tube 1013 is fixedly connected to the side wall of the guide frame 1002. The inner wall surface of the guide frame 1002 is rotatably connected to a plurality of impellers 1011. The impellers 1011 are rotated by the wind, thereby effectively driving the flow of the flame retardant. The plurality of impellers 1011 are evenly distributed on the inner wall surface of the guide frame 1002.

[0047] When the entire transformer body 2 is at an overheated temperature and burns occur, the interior of the transformer body 2 can be protected with the help of the protection mechanism 10. At this time, protection is provided by the flame retardant placed in the carrier frame 1001. Prior to this, the flame retardant is placed in the carrier frame 1001 through the feed frame 1003 on the side wall of the carrier frame 1001. When the temperature is too high, the temperature sensor 1005 will capture it and send the signal to the central controller 1010. At the same time, with the help of the signal processor 1006 and the cylinder 1004, the cylinder 1004 is started to drive the push plate 1008 to move, and the flame retardant in the carrier frame 1001 is pushed into the guide frame 1002, and scattered with the help of the seepage hole 1012. At the same time, the fan module 1007 is started to send wind to the guide frame 1002 to drive the fan wheel 1011 to rotate, which helps to better scatter the flame retardant and protect the interior of the transformer body 2.

[0048] In an outdoor environment, most transformer bodies 2 are set on the surface of the mounting frame 1. During this process, the lifting mechanism 7 set on both sides of the top plate 3 on the upper surface of the transformer body 2 is used to move the entire transformer body 2 to the surface of the mounting frame 1, and then the mounting mechanism 6 set on the base 8 on the lower surface of the transformer body 2 is used to fix the position of the entire transformer body 2. After long-term use, a large amount of heat will be generated inside the transformer body 2, causing the internal temperature to rise. In order to avoid explosion, the heat dissipation and explosion-proof mechanism 5 set on the bottom side wall of the transformer body 2 is used for assistance, and the water pump 502 is used to circulate the water in the water tank 503 through the water inlet pipe 504, the water outlet pipe 505 and the docking pipe 517, so that the heat dissipation plate 511 on one side of the internal protective frame 509 of the transformer body 2 absorbs heat, and the entire transformer body 2 is cooled.
