Description

Technical Field

[0001] The 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 the principle of electromagnetic induction to change the AC voltage level. It is mainly composed of two sets of coils, primary coils and secondary coils, an iron core or magnetic core, and insulating materials. Among them, the outdoor explosion-proof power control transformer has a special explosion-proof structure to prevent the sparks or high temperatures that may be generated inside from causing an explosion in the external environment. It is more common in transformer substations.

[0003] Prior art includes an invention with publication number CN112802663B, which discloses an outdoor transformer, which includes a transformer body, and a plurality of heat sinks are installed on the outside of the transformer body, and a reinforcing rib is fixed on the side of the heat sink away from the transformer body. For this outdoor transformer, when leaves are on the top of the reinforcing rib, the heat dissipation effect of the heat sink covered by the leaves becomes poor, and the temperature of the driving 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 insulation driving block, the heat insulation driving block will move and the cleaning plate will rise through the driving mechanism and the transmission mechanism, and the rising cleaning plate is on the side of the heat sink with higher temperature. When the cleaning plate rises, it will push the leaves to rise and move the leaves. During the movement of the leaves, the leaves will slide on the heat sink, thereby reducing the stability of the leaves, and then the leaves will 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 an increase in heat generation, which can easily cause explosion damage to the entire transformer.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] 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 of the following disclosure.

[0023] Embodiment 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 matching the internal electrical components, thereby generating the electromagnetic induction principle to change the AC voltage level, and at the same time, the voltage conversion ratio of the transformer body 2 is determined by the turns ratio of the windings 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 at the upper end of the transformer body 2. During the long-term operation and use of the transformer body 2, heat is generated due to the iron loss and copper loss inside the transformer body 2. At the same time, as the load increases, the loss will also increase accordingly, resulting in an increase in the amount of heat generated, and 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 bearing frame 1001 is used for protection, and the flame retardant is used to prevent the transformer body 2 from burning. The cylinder 1004 drives the push rod to move, and pushes the flame retardant in the bearing 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, 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 can be used for protection. The water pump 502, the water inlet pipe 504, the water outlet pipe 505 and the heat sink 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 surface of the top plate 3 can be used for assistance. The hoisting ring 75 can be used to effectively and conveniently lift the entire transformer body 2 to a 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 is used to drive the extrusion blocks 64 on both sides of the mounting plate 61 to be squeezed and fixed with the side walls of the mounting frame 1, so as to quickly and conveniently perform fixed limit operations with the mounting frame 1.

[0024] 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 bottom end of the water storage tank 503 is fixedly connected with a conduit 508, and the water source is conveniently transported to the water pump 502 through the conduit 508. The bottom end of the conduit 508 is fixedly connected to the connecting pipe 506, and the arc surface of the conduit 508 is installed with a solenoid valve 507. The solenoid valve 507 can be used to control 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 with the same butt joint pipe 517. The cross-section of the butt joint pipe 517 is "S" shaped. The heat absorbed by the surface of the heat sink 511 can be absorbed and dissipated through the butt joint pipe 517. The butt joint 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, and the transformer body 2 can be further protected by the protective frame 509 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.

With the help of the inlay groove 518, the heat sink 511 can be easily and quickly penetrated and limited with the docking tube 517. The inner wall of the inlay groove 518 slides through the surface of the docking tube 517. The side wall of the protective frame 509 is fixedly connected with a connecting plate 515. 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 a 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, so as to facilitate the clamping and fixing of the position of the heat sink 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 sink 511.The arc surface of the moving rod 514 is sleeved with a spring 516, and the tension generated by the spring 516 is used to better squeeze and fix the limit frame 513. The two ends of the spring 516 are fixedly connected to the moving rod 514 and the connecting plate 515 respectively. The protective frame 509 is a cast iron frame. The cast iron material has good mechanical strength and corrosion resistance, which is suitable for harsh environments and is convenient for better protection of the transformer body 2. The cross-section of the protective frame 509 is rectangular, and the cross-sectional size of the protective frame 509 is compatible with the inner wall size of the transformer body 2.

[0026] When the transformer body 2 is operated for a long time, the inside 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 and performs a cooling operation, thereby effectively and conveniently reducing the temperature of the inner wall of the transformer body 2.

The push plate 1008 is convenient for pushing the flame retardant into the guide frame 1002. The two side surfaces of the push plate 1008 are fixedly connected with adjustment plates 1009. The adjustment plates 1009 are inclined. With the help of the adjustment plates 1009, the flame retardant in the carrier frame 1001 can be pushed better. The cross-sectional size of the push plate 1008 is adapted to the cross-sectional size of the inner wall of the carrier frame 1001.

[0032] When the temperature of the entire transformer body 2 is too high and burning occurs, the protection mechanism 10 can be used to protect the interior of the transformer body 2. At this time, the flame retardant placed in the carrier frame 1001 is used for protection. 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.

[0033] In an outdoor environment, most transformer bodies 2 are arranged on the surface of the mounting frame 1. During this process, the lifting mechanism 7 arranged 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 arranged 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 arranged on the bottom side wall of the transformer body 2 is used for assistance. 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 sink 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.
