Description

Technical Field

[0001] The present invention relates to the field of transformers, and more particularly to an outdoor box-type transformer. Background Art

[0002] Outdoor box-type transformers need to have good sealing performance to prevent rainwater and dust from entering and affecting the internal main body of the box-type transformer. However, due to the long-term influence of the sealing glue and the external environment, the sealing rubber parts will be accelerated in aging, resulting in deterioration, cracking, deformation, and thus failure, reducing the sealing performance of the outdoor box-type transformer and making it impossible to protect the internal main body from rain and dust.

[0003] For example: The "Outdoor Transformer" disclosed in the Chinese invention patent (Publication No.: CN111816408A) has a description in its specification that waterproof transformers generally have a special protective shell or cover, and the internal transformer is treated by potting, which can cope with harsh environments such as high temperature, humidity, rain, and water immersion, with a relatively high IP protection level, and has been widely used in industries such as outdoor lighting, urban lighting projects, mining areas, ship equipment, electronic bathroom equipment, industrial atomizing humidifiers, medical equipment, and precision instruments. When used outdoors, due to the large changes in environmental factors, waterproof transformers must have good heat dissipation performance. The existing waterproof transformers use sealing treatment, and their heat dissipation performance is difficult to fully meet the environmental changes. Therefore, providing a transformer with both good waterproof performance and good heat dissipation performance is a current trend in technology research and development; the above patent can prove the existing defects.

[0004] Therefore, we make improvements and propose an outdoor box-type transformer. Summary of the Invention

[0018] Advantages of the present invention:

[0019] In the solution of the present application:

[0020] 1. To solve the problem of the sealing performance degradation caused by the aging of the sealing rubber, the present application sets up a repair component to utilize the aging of the sealing strip and the release of the suction cup adsorption, so that the screw roller can rotate under the action of the first impeller, cut the aging part of the sealing strip, and through the setting of the push plate and the compression spring, move the cut part of the sealing strip upward. At the same time, the sealing plate squeezes the glue storage cavity, and under the action of the glue guiding hole and the glue injection needle, the glue liquid inside the glue storage cavity is transported to the bottom of the push plate. After the glue liquid solidifies, the cut part of the sealing strip is repaired, improving the rain and dust protection effect of the transformer;

[0021] 2. To solve the problem of poor heat dissipation during the use of the transformer, the present application sets up a heat dissipation component to drive the second impeller to rotate by using a servo motor, so that the hot air in the bottom box can be transported to the heat dissipation cavity. The hot air moves from the shunt groove to the assembly cavity and is then collected by the air collecting hood. Through the corrugated pipe, the hot air can be transported to the assembly cavity, thereby driving the first impeller to rotate, and driving the second impeller to rotate in the reverse direction through the transmission shaft. Thus, the residence time of the hot air in the assembly cavity is increased. At the same time, since the inside of the transmission shaft is hollow, the external air can circulate inside the transmission shaft, thereby improving the cooling of the hot air and achieving effective temperature reduction inside the transformer;

[0022] 3. Through the set lifting component, the bidirectional lead screw can drive the lead screw sleeve to move closer, so that the main body can be lifted to the top of the bottom box through the bearing plate, facilitating the maintenance personnel to perform a full range of inspections on the main body. At the same time, when the main body descends into the bottom box, the shock absorption ring can abut against the lead screw sleeve, and the slider can abut against the shock absorption plate. Under the action of the first return spring and the second return spring, it can play a shock absorption role on the main body, thereby reducing the noise generated during the use of the transformer.

Detailed implementation manner

[0040] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0041] As described in the background art, due to the long-term influence of the sealing gum and the external environment, the sealing rubber parts will be accelerated in aging, resulting in deterioration, cracking, and deformation, and thus failure, reducing the sealing performance of the outdoor box-type transformer and making it impossible to protect the main body inside from rain and dust.

[0042] To solve this technical problem, the present invention provides an outdoor box-type transformer, which is applied to a transformer.

[0043] Specifically, please refer to Figure 1-12 , the outdoor box-type transformer specifically includes:

[0044] Bottom box 1, a cover plate 101 is provided on the top of the bottom box 1, a main body 102 is provided inside the bottom box 1, square placement grooves 103 are opened at the docking positions between the top of the bottom box 1 and the bottom of the cover plate 101, and sealing rubber strips are provided in the square placement grooves 103. It is characterized in that a repair component 2 is provided inside the cover plate 101, the repair component 2 is designed corresponding to the square placement groove 103, the repair component 2 is composed of several repair units 200, the repair unit 200 includes an assembly cavity 218 opened inside the cover plate 101, the repair unit 200 includes all the structures inside the assembly cavity 218, an impeller 1 202 is rotatably installed in the assembly cavity 218, a plurality of glue storage cavities 201 are opened at the bottom of the assembly cavity 218, the glue storage cavities 201 are designed corresponding to the repair unit 200, a connecting shaft 203 is fixedly installed at the bottom of the impeller 1 202 and is located in the glue storage cavity 201, and the inside of the connecting shaft 203 is designed to be hollow;

[0045] A sealing plate 211 is installed in the glue storage cavity 201 in a piston-like sliding manner. A screw roller 204 is rotatably installed at the bottom of the sealing plate 211. The bottom of the coupling shaft 203 is designed with a snap connection to the top of the screw roller 204. A glue injection needle 206 is provided at the bottom of the coupling shaft 203. The inside of the glue injection needle 206 is communicated with the inside of the coupling shaft 203. A suction cup 208 is fixedly installed at the bottom of the screw roller 204 and can adsorb the sealing strip. A plurality of glue guiding holes 215 are arrayed on the outer wall of the coupling shaft 203. Cutting blades 207 are snap-connected to both sides of the screw roller 204. A plurality of push plates 209 are arrayed and installed at the bottom of the placement groove 103. The push plates 209 are designed in correspondence with the repair unit 200. A compression spring 210 is fixedly installed between the bottom of the push plate 209 and the bottom box 1;

[0046] A heat dissipation component 3 is provided inside the cover plate 101. The heat dissipation component 3 is communicated with the assembly cavity 218. When the adsorption between the suction cup 208 and the sealing strip is released, it can drive the impeller one 202 to rotate, thereby triggering the repair unit 200 to repair the sealing strip.

[0047] The outdoor box-type transformer provided by the present invention is to solve the problem that the long-term influence of the sealing glue and the external environment will cause the sealing rubber parts to age rapidly, resulting in deterioration, cracking, deformation, and thus failure, reducing the sealing performance of the outdoor box-type transformer and being unable to protect the main body inside it from rain and dust. Through the setting of the repair component 2, several repair units 200 can separately repair any part of the sealing strip. By setting the suction cup 208 fixedly installed at the bottom of the screw roller 204, it can form adsorption with the sealing strip, so that the impeller one 202 cannot rotate under the action of the wind force generated by the heat dissipation component 3. When the sealing strip ages, the adsorption between the suction cup 208 and the sealing strip is released, and the impeller one 202 can rotate under the drive of the heat dissipation component 3, thereby driving the screw roller 204 to rotate through the coupling shaft 203. The screw roller 204 is designed with a snap connection to the cutting blades 207 provided on both sides, so that the cutting blades 207 cut the sealing strip. When the sealing strip is cut off, under the action of the push plate 209 and the compression spring 210, the cut part of the sealing strip moves upward, thereby squeezing the screw roller 204 upward, and at the same time driving the sealing plate 211 to move upward to squeeze the inside of the glue storage cavity 201. At the same time, the glue injection needle 206 fixedly installed at the bottom of the coupling shaft 203 can pierce the sealing strip through the push plate 209, and convey the glue liquid inside the glue storage cavity 201 to the bottom of the push plate 209 through the glue guiding holes 215 and the glue injection needle 206. The glue liquid will solidify at the bottom of the push plate 209 due to the entry of air, thereby sealing the repaired part, and thus being able to separately repair any part of the sealing strip, preventing the sealing strip from aging and failing to protect the main body inside the transformer from rain and dust.

[0048] To enable those skilled in the art to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings.

[0049] It should be noted that, without conflict, the embodiments in the present invention and the features and technical solutions in the embodiments can be combined with each other.

[0050] It should be noted that similar reference numerals and letters denote similar items in the following drawings. Therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.

[0051] Example 1, please refer to Figure 2 and Figures 4-7 , an outdoor box-type transformer, which includes a bottom box 1. A cover plate 101 is provided on the top of the bottom box 1. A main body 102 is provided inside the bottom box 1. Square placement grooves 103 are opened at the docking positions between the top of the bottom box 1 and the bottom of the cover plate 101. A sealing rubber strip is provided in the square placement groove 103. It is characterized in that a repair component 2 is provided inside the cover plate 101. The repair component 2 is designed corresponding to the square placement groove 103. The repair component 2 is composed of several repair units 200. The repair unit 200 includes an assembly cavity 218 opened inside the cover plate 101. An impeller one 202 is rotatably installed in the assembly cavity 218. A plurality of glue storage cavities 201 are opened at the bottom of the assembly cavity 218. The glue storage cavities 201 are designed corresponding to the repair units 200. A connecting shaft 203 is fixedly installed at the bottom of the impeller one 202 and is located in the glue storage cavity 201. The inside of the connecting shaft 203 is hollow-designed;

[0052] Sealing plates 211 are piston-slidably installed in the glue storage cavities 201. A screw roller 204 is rotatably installed at the bottom of the sealing plate 211. The bottom of the connecting shaft 203 and the top of the screw roller 204 are designed for snap connection. A glue injection needle 206 is provided at the bottom of the connecting shaft 203. The inside of the glue injection needle 206 is communicated with the inside of the connecting shaft 203. A suction cup 208 is fixedly installed at the bottom of the screw roller 204 and can adsorb the sealing rubber strip. A plurality of glue guiding holes 215 are arrayed on the outer wall of the connecting shaft 203. Cutting blades 207 are snap-connected on both sides of the screw roller 204. A plurality of push plates 209 are arrayed and installed at the bottom of the placement groove 103. The push plates 209 are designed corresponding to the repair units 200. A compression spring 210 is fixedly installed between the bottom of the push plate 209 and the bottom box 1;

[0053] A heat dissipation component 3 is provided inside the cover plate 101. The heat dissipation component 3 is communicated with the assembly cavity 218. When the adsorption between the suction cup 208 and the sealing rubber strip is released, it can drive the impeller one 202 to rotate, thereby triggering the repair unit 200 to repair the sealing rubber strip;

[0054] An isolation film 214 is provided inside the glue storage cavity 201. Mother glue and a catalyst are provided in the glue storage cavity 201 and are separated by the isolation film 214. A plurality of stirring rods 205 are slidably installed at the top of the screw roller 204;

[0055] A plurality of second wedge blocks 216 are slidably installed in an array on the outer wall of the coupling shaft 203. A second spring 217 is fixedly installed between the outer walls of the plurality of second wedge blocks 216 and the inside of the coupling shaft 203. The second wedge blocks 216 are designed to be clamped with the top of the screw roller 204;

[0056] Two first wedge blocks 212 are symmetrically and slidably installed on the outer walls on both sides of the cutting blade 207. A first spring 213 is fixedly installed between the two first wedge blocks 212 and is located inside the cutting blade 207. The two first wedge blocks 212 are respectively designed to be clamped with the two screw rollers 204.

[0057] In order to solve the problem that the long-term influence of the sealed glue and the external environment will cause the sealed rubber parts to age rapidly, resulting in deterioration, cracking, deformation, and thus failure, which will reduce the sealing performance of the outdoor box-type transformer and cannot protect the internal main body from rain and dust, in this application, by setting the repair component 2, a plurality of repair units 200 can separately repair any part of the sealed rubber strip. By setting the suction cup 208 fixedly installed at the bottom of the screw roller 204, it can form an adsorption with the sealed rubber strip, so that the impeller one 202 cannot rotate under the action of the wind force generated by the heat dissipation component 3. When the sealed rubber strip ages, the adsorption between the suction cup 208 and the sealed rubber strip is released, and the impeller one 202 can rotate under the drive of the heat dissipation component 3, thereby driving the screw roller 204 to rotate through the coupling shaft 203. The screw roller 204 is designed to be clamped with the cutting blades 207 arranged on both sides, so that the cutting blades 207 cut the sealed rubber strip. When the sealed rubber strip is cut off, under the action of the push plate 209 and the compression spring 210, the cut part of the sealed rubber strip moves upward, thereby squeezing the screw roller 204 upward, and at the same time driving the sealing plate 211 to move upward to squeeze the inside of the glue storage cavity 201. At the same time, the glue injection needle 206 fixedly installed at the bottom of the coupling shaft 203 can pierce the sealed rubber strip through the push plate 209, and convey the glue liquid inside the glue storage cavity 201 to the bottom of the push plate 209 through the glue guiding hole 215 and the glue injection needle 206. After the glue liquid solidifies at the bottom of the push plate 209, it seals the repaired part, and thus can separately repair any part of the sealed rubber strip, preventing the sealed rubber strip from aging and failing to protect the internal main body of the transformer from rain and dust.

[0058] Specifically, by setting a plurality of second wedge blocks 216 slidably mounted on the outer wall of the coupling shaft 203, which can form a clamping connection with the top of the screw roller 204. When the sealing strip ages and the adsorption of the suction cup 208 is released, the heat dissipation component 3 drives the first impeller 202 to rotate. Thus, through the coupling shaft 203 fixedly installed at the bottom of the impeller 202, using the clamping design of the second wedge block 216 and the screw roller 204, the screw roller 204 is driven to rotate. The first wedge block 212 provided on the screw roller 204 and the cutting blade 207 is designed for threaded clamping, so that the cutting blade 207 can be driven to move downward to cut the sealing strip. Through the first wedge block 212 on the other side of the cutting blade 207 and the design of the first spring 213 and the inclined plane, the other first wedge block 212 does not affect the downward movement of the cutting blade 207. After the sealing strip is cut off, under the action of the push plate 209 and the compression spring 210, the cut part of the sealing strip moves upward. At the same time, when the first impeller 202 rotates to drive the screw roller 204 to rotate, a plurality of stirring rods 205 arranged in an array on the top of the screw roller 204 rotate inside the glue storage cavity 201, causing the isolation film 214 to rupture. Thus, the mother glue and the catalyst inside the glue storage cavity 201 are fully mixed under the action of the stirring rods 205. Then, through the glue guiding hole 215 and the injection needle 206, under the extrusion of the sealing plate 211 on the inside of the glue storage cavity 201, the glue liquid is conveyed to the bottom of the push plate 209 to solidify, thereby repairing the aged part of the sealing strip.

The first wind wheel 310 and the second wind wheel 312 are designed with the same axis.

A plurality of transmission shafts 311 are rotatably installed through the assembly roller 304 in an array. The plurality of transmission shafts 311 are in meshing design with the inner circumferential outer wall of the first wind wheel 310 and the outer circumferential outer wall of the second wind wheel 312. The inside of the transmission shaft 311 is designed to be hollow.

[0062] To solve the problem that the transformer generates heat during use and will be damaged if the heat cannot be dissipated in time, in this application, a heat dissipation component 3 is set up to drive the second impeller 302 to rotate by a servo motor 301, so that the hot air inside the bottom box 1 is transported into the heat dissipation cavity 308. By setting a plurality of diversion grooves 309 to communicate with the heat dissipation cavity 308 and the assembly cavity 218, the flowing air generated by the second impeller 302 can flow into the assembly cavity 218 through the plurality of diversion grooves 309, so as to act on the first impeller 202 in a plurality of repair units 200. When the suction cup 208 is released from the adsorption with the sealing strip, the first impeller 202 can rotate by generating a wind direction force through the diversion groove 309. By setting a wind collecting hood 303, the hot air transported by the second impeller 302 can be collected. Through the corrugated pipe 305 arranged at the bottom of the wind collecting hood 303, when the hot air is sent into the assembly roller 304, the corrugated pipe 304 can form a threaded connection with the bottom of the wind collecting hood 303 through the sleeve ring 307 rotatably installed at the end, so that the inside of the wind collecting hood 303 is communicated with the inside of the assembly roller 304. When the hot air enters the inside of the assembly roller 304, it can drive the first wind wheel 310 to rotate. Under the mutual meshing action of the transmission shaft 311, the first wind wheel 310 and the second wind wheel 312, the second wind wheel 312 is driven to rotate in the reverse direction. Through the plurality of communication holes 314 arrayed and penetrated through the inner circumferential outer walls of the first impeller 310 and the second impeller 312, the hot air can flow, so as to increase the residence time of the hot air inside the assembly roller 304, enable the hot air to be fully cooled, and then the cooled air inside the assembly roller 304 is transported into the bottom box 1 through the electric telescopic pipe 306, so as to play a role in heat dissipation and temperature reduction. By setting the inside of the transmission shaft 311 to be hollow and rotatably installed through the assembly roller 304, the cold air outside can circulate inside the transmission shaft 311, reducing the temperature of the transmission shaft 311, further improving the cooling of the hot air, and improving the heat dissipation and temperature reduction efficiency inside the bottom box 1.

[0063] Example 3 further optimizes the outdoor box-type transformer provided in Example 1 or 2. Specifically, as Figures 9-12As shown in the figure, a lifting assembly 4 is provided inside the bottom box 1. The lifting assembly 4 includes two bidirectional lead screws 401 symmetrically and rotatably installed inside the bottom box 1. Two receiving plates 402 are symmetrically installed at the bottom of the main body 102 and are designed in a corresponding manner with the two bidirectional lead screws 401. Two screw sleeves 405 are symmetrically slidably installed on the outer wall of the bidirectional lead screw 401. On the inner circumferential outer walls of the two screw sleeves 405, clamping blocks 416 are fixedly installed and are in threaded clamping connection with the bidirectional lead screw 401. On the outer walls of the two screw sleeves 405, a first connecting rod 403 and a second connecting rod 404 are respectively hingedly installed, and the first connecting rod 403 and the second connecting rod 404 are hingedly connected. At the ends of the first connecting rod 403 and the second connecting rod 404, sliding blocks 406 are hingedly installed. The two sliding blocks 406 are both slidably installed at the bottom of the receiving plate 402;

[0064] Both ends of the bidirectional lead screw 401 are hollow. On the outer wall of the bidirectional lead screw 401, sliding grooves 415 are symmetrically opened and are respectively communicated with the hollow parts at both ends. The ends of the two sliding grooves 415 are butted against the spiral grooves of the bidirectional lead screw 401. Inside any one end of the bidirectional lead screw 401, a lead screw 412 is rotatably installed and penetrates through the outer wall of the bottom box 1. A nut sleeve 413 is threadedly clamped on the outer wall of the lead screw 412 and is located inside the bidirectional lead screw 401. A resisting block 414 is fixedly installed on the outer wall of the nut sleeve 413 and slides inside the sliding groove 415. An adjusting nut 417 is fixedly installed at the end of the lead screw 412 and is located outside the bottom box 1;

[0065] At both ends of the receiving plate 402, second return springs 411 are fixedly installed. At the ends of the two second return springs 411, shock-absorbing plates 410 are fixedly installed. At both ends of the bidirectional lead screw 401, flanges 409 are fixedly installed. On the outer walls of the two flanges 409, first return springs 408 are fixedly installed. At the ends of the two first return springs 408, shock-absorbing rings 407 are fixedly installed and are coaxially designed with the bidirectional lead screw 401.

[0066] To solve the problem that maintenance is required inside the transformer, in this application, a lifting assembly 4 is provided. When the reciprocating lead screw 401 rotates, it can drive two lead screw sleeves 405 to approach each other through the clamping design of the clamping block 416. The first connecting rod 403 and the second connecting rod 404 are respectively hinged to the two lead screw sleeves 405, so that the slider 406 hinged to the ends of the first connecting rod 403 and the second connecting rod 404 can slide close to the bottom of the receiving plate 402. Furthermore, the main body 103 can be lifted by the receiving plate 402, and the main body 103 can be displaced to the top of the bottom box 1, facilitating all-round maintenance of the main body 103 by maintenance personnel. Compared with the open-door type transformer shell, the maintenance is more convenient and there will be no dead corners or inconvenient maintenance directions. By setting the end of the chute 415 to be docked with the helical groove of the bidirectional lead screw 401, when the main body 103 descends into the bottom box 1, the lead screw sleeve 405 is displaced to a certain position, and the clamping connection between the clamping block 416 and the bidirectional lead screw 401 is released. The clamping block 416 can slide in the chute 415, so that the lead screw sleeve 405 abuts against the shock-absorbing ring 407, and the slider 406 abuts against the shock-absorbing plate 410 provided at the bottom of the receiving plate 402. Under the action of the first return spring 408 and the second return spring 411, it can play a shock-absorbing role, thereby reducing the noise generated during the use of the transformer and playing a role in noise reduction. By setting the lead screw 412 and the nut sleeve 413 threadedly clamped thereto, and the abutting block 414 fixedly installed on the outer wall of the nut sleeve 413 slides in the chute. When the main body 1 needs to be displaced to the top of the bottom box 1, by rotating the adjusting nut 417 to drive the lead screw 412 to rotate, the abutting block 414 can be driven to displace in the chute 415 and abut against the clamping block 416. At the same time, the abutting block 416 is driven to synchronously displace into the helical groove of the bidirectional lead screw 401. At the same time, the abutting block 414 cannot be displaced, so as to drive the bidirectional lead screw 401 to rotate, thereby driving the two lead screw sleeves 405 to approach and displace, and further displacing the main body 103 to the top of the bottom box 1 for convenient maintenance.

[0067] The usage process of the outdoor box-type transformer provided by the present invention is as follows:

[0068] First, the servo motor 301 drives the impeller two 302 to rotate, causing the hot air inside the bottom box 1 to move into the heat dissipation cavity 308. The hot air is transported into the assembly cavity 218 through the shunt groove 309. At the same time, the flowing hot air can act on the impeller one 202. When the sealing strip ages and the adsorption of the suction cup 208 is released, the impeller one 202 rotates under the action of the hot air, thereby driving the screw roller 204 to rotate, driving the stirring rod 205 to rotate in the glue storage cavity 201, causing the isolation film 214 inside the glue storage cavity 201 to rupture, and mixing the mother glue and catalyst inside the glue storage cavity 201 under the action of the stirring rod 205. At the same time, the rotation of the screw roller 204 can cause the cutting blades 207 on both sides to move downward, cutting the aged part of the sealing strip. When the sealing strip is cut off, under the action of the push plate 209 and the compression spring 210, the cut part of the sealing strip moves upward, thereby driving the sealing plate 211 to extrude the inside of the glue storage cavity 201. Under the action of the glue guiding hole 215 and the glue injection needle 206, the glue liquid can be transported to the bottom of the push plate 209, and the solidification of the glue liquid can repair the cut part of the sealing strip;

[0069] At the same time, the hot air can be collected by the air collecting hood 303, and the hot air inside the air collecting hood 303 is transported into the assembly roller 304 through the corrugated pipe 305. When the hot air enters the inside of the assembly roller 304, it can drive the wind wheel one 310 to rotate. Under the meshing action of the transmission shaft 311 with the wind wheel one 310 and the wind wheel two 312, the wind wheel two 312 is driven to rotate in the reverse direction. Through a plurality of communication holes 314 arrayed through the inner and outer walls of the impeller one 310 and the impeller two 312, the hot air can flow, so that the residence time of the hot air inside the assembly roller 304 can be increased, enabling the hot air to be fully cooled. Then, the cooled air inside the assembly roller 304 is transported into the bottom box 1 through the electric telescopic pipe 306, thereby playing a role in heat dissipation and temperature reduction. By setting the inside of the transmission shaft 311 to be hollow and rotatably installed through the assembly roller 304, the outside cold air can circulate inside the transmission shaft 311, reducing the temperature of the transmission shaft 311, further improving the cooling of the hot air, and improving the heat dissipation and temperature reduction efficiency inside the bottom box 1;

[0070] Under the action of the lifting assembly 4, the main body 103 can be driven to move to the top of the bottom box 1, which is convenient for maintenance personnel to perform a full range of inspections on the main body 103. At the same time, when the main body 1 moves into the bottom box 1, by setting the shock absorption ring 407 to be in contact with the lead screw sleeve 405 and the slider 406 to be in contact with the shock absorption plate 410, under the action of the first return spring 408 and the second return spring 411, the main body 103 can be shock-absorbed, thereby reducing the noise generated during the use of the transformer.
