Description

TECHNICAL FIELD

[0001] The application relates to the technical field of voltage transformers, in particular to a voltage transformer. BACKGROUND

[0002] The voltage transformer is a special transformer specially used in the power system. The voltage transformer reduces the high voltage on the primary side to a safe and standard low voltage according to a set transformation ratio, and sends the low voltage to the measuring or control equipment such as the voltage meter, power meter and relay protection device through the primary and secondary electrical isolation, so as to realize the accurate measurement and protection of the high-voltage line voltage.

[0003] In the related art, the voltage transformer comprises a shell, a plurality of windings are arranged on the shell, a conductive sheet is fixedly connected to the plurality of windings, and a wire is fixedly connected to the conductive sheet through a bolt.

[0004] When the voltage transformer is in use, the wire usually has a partial excess design, that is, the length of the wire is relatively long. The wire is prone to falling and being placed, which may cause the tension between the wire and the conductive sheet to be too large, thereby affecting the normal use of the voltage transformer. SUMMARY

[0005] In order to improve the problem that the excessively long wire affects the voltage transformer, the application provides a voltage transformer.

[0006] The application provides a voltage transformer, which adopts the following technical scheme: The voltage transformer comprises a shell, a plurality of windings are arranged on the shell, a conductive sheet is arranged on the windings, an extension sheet is arranged on the conductive sheet, a plurality of mounting rods are arranged on the extension sheet, the plurality of mounting rods are divided into two groups, the mounting rods in different groups are arranged alternately, the mounting rods in the same group are distributed along the length direction of the extension sheet, and the mounting rods are used for winding the wire.

[0007] By arranging the extension sheet on the conductive sheet and arranging the mounting rods in different groups alternately and distributing the mounting rods in the same group along the length direction of the extension sheet, the worker can arrange the wire in an S shape and wind the wire around the mounting rods in different groups, so that the mounting rods can support the wire and prevent the wire from falling on the conductive sheet, thereby avoiding the adverse effects caused by the excessively long wire.

[0008] Optionally, the extension sheet is provided with a containing groove, a rotating rod is arranged in the containing groove, the mounting rod is rotatably connected to the rotating rod, a torsional spring is arranged on the rotating rod, the torsional spring is used for driving the mounting rod to be separated from the containing groove, and the wire abuts against one side of the mounting rod away from the opening of the containing groove.

[0009] By adopting the above technical solution, when the conductor is pulled by external factors such as wind or external personnel, the conductor can be rotated and connected to the rotating rod through the mounting rod. The conductor can drive the mounting rod to rotate, so that the conductor can still provide a margin when it is wound, so that the conductor can provide a margin during the process of being pulled, thus extending the service life of the conductor.

[0010] Optionally, the mounting rod is provided with a mounting block, which is located at the end of the mounting rod away from the rotating rod.

[0011] By adopting the above technical solution, when the mounting rod is completely located in the receiving groove, the mounting block is located at the end of the mounting rod away from the rotating rod, so that the mounting block can restrict the movement of the wire on the extension plate. If the external factors weaken, such as the wind decreases and the outside people stop pulling, the torsion spring can drive the mounting rod to rotate and reset. At this time, the mounting block can restrict the wire from still passing around the mounting rod, avoiding the situation where the wire continues to fall due to being pulled.

[0012] Optionally, the mounting block is provided with a mounting spring, which deforms toward the mounting rod, and the wire is located between the mounting spring and the mounting rod.

[0013] By adopting the above technical solution, the installation spring deforms in the direction of the mounting rod, and the wire is located between the installation spring and the mounting rod. This allows the installation spring to restrict the wire from moving away from the ground, that is, the installation spring can prevent the wire from floating up, thereby allowing the wire to be more stably located on the mounting rod and increasing the stability of the wire on the mounting rod.

[0014] Optionally, a fixing groove is provided on the outer surface of the mounting rod, a fixing spring is provided in the fixing groove, a fixing plate is provided on the fixing spring, an extension strip is provided on the extension plate, the fixing spring drives the fixing plate to abut against the extension strip, and a wire is placed between the fixing plate and the extension strip.

[0015] By adopting the above technical solution, the fixing plate is moved by the fixing spring, so that the fixing plate can abut against the wire, and the wire can be located between the fixing plate and the extension strip, thereby fixing the wire to the mounting rod. By fixing the wire to the mounting rod, the connection between the wire and the conductive plate is less likely to become unstable due to pulling.

[0016] Optionally, the mounting rod is provided with a mounting gear, and multiple stop strips are slidably connected to the extension plate. The stop strips are engaged with the mounting gear, and the stop strips and the mounting rod are staggered. The rotating rod is provided with a stop groove for the stop strips to be inserted. When the mounting rod is completely located in the receiving groove, the stop strip disengages from the stop groove of the next mounting rod.

[0017] By adopting the above technical solution, when the mounting rod rotates, the mounting rod drives the stop strip to move through the mounting gear, allowing the stop strip to disengage from the stop groove. This releases the stop strip from restricting the next mounting rod, allowing the next mounting rod to rotate with the conductor. When the mounting rod is not fully within the receiving groove, the stop strip is located within the stop groove of the next mounting rod, making it difficult for the next mounting rod to rotate. This avoids the situation where the mounting rods in the same group tilt simultaneously due to strong winds, causing the conductor to fall too far at once.

[0018] Optionally, the mounting rod is provided with a stop block, the stop groove is formed on the stop block, the extension piece is provided with a plurality of receiving grooves, the receiving grooves and the receiving grooves are staggered, the stop strip is slidably connected in the receiving groove, the receiving groove is provided with a receiving hole communicating with the receiving groove, and the receiving hole allows the stop block to pass through.

[0019] By adopting the above technical solution, when the mounting rod rotates, the mounting rod drives the stop strip to move through the mounting gear. The receiving groove and the receiving groove are arranged alternately, and the stop block passes through the receiving hole and is located in the receiving groove, so that the stop strip can be stably inserted into the stop groove.

[0020] Optionally, the receiving groove is inclined, with the end of the receiving groove near the receiving hole being lower than the end of the receiving groove away from the receiving hole.

[0021] By adopting the above technical solution, when it rains, rainwater accumulates in the receiving tank. Through the inclined setting of the receiving tank, the accumulated water can flow through the receiving tank, the receiving hole, and the receiving tank in sequence. At this time, the rainwater can flow from the receiving hole into the receiving tank, reducing the water accumulation in the receiving tank and making it less likely for the wire to be directly immersed in the accumulated water.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. An extension plate is placed on the conductive sheet, and different groups of mounting rods are staggered. The mounting rods in the same group are distributed along the length of the extension plate. The operator sets the wire in an S-shape, passing around multiple groups of mounting rods, so that the mounting rods can support the wire and prevent the wire from sagging on the conductive sheet, avoiding the adverse effects caused by the wire being too long.

[0023] 2. When the mounting rod is fully inside the receiving groove, the mounting block is located at the end of the mounting rod away from the rotating rod, which allows the mounting block to restrict the movement of the wire on the extension plate. If external factors weaken, such as when the wind decreases or when people stop pulling, the torsion spring can drive the mounting rod to rotate and reset. At this time, the mounting block can restrict the wire from still passing around the mounting rod, preventing the wire from continuing to fall due to being pulled. Attached Figure Description

[0026] The following is in conjunction with the appendix Figures 1-4 This application will be described in further detail.

[0027] This embodiment discloses a voltage transformer. (Refer to...) Figure 1 A voltage transformer includes a housing 1, on which multiple windings 11 are fixedly connected, and the multiple windings 11 are respectively disposed on different sides of the housing 1. Conductive plates 12 are fixedly connected to the windings 11, and the conductive plates 12 are used for wire connection. The distance between the conductive plates 12 and the ground gradually decreases along the direction from one side of the winding 11 to the other side of the winding 11.

[0028] Reference Figure 2 An extension piece 2 is fixedly connected to the surface of the conductive sheet 12, and the tilt direction of the extension piece 2 is the same as that of the conductive sheet 12. Multiple receiving grooves 21 are formed on the surface of the extension piece 2 away from the ground, extending along the width direction of the extension piece 2. Multiple receiving slots 22 are also formed on the surface of the extension piece 2 away from the ground, extending along the width direction of the extension piece 2. The multiple receiving grooves 21 and 22 are arranged in an array along the length direction of the extension piece 2, and are staggered.

[0029] Reference Figure 3 The receiving groove 21 has a receiving hole 221 on its groove wall, the receiving hole 221 is connected to the receiving groove 22, and the receiving hole 221 is located on one side of the receiving groove 21.

[0030] Reference Figure 2 and Figure 3The receiving groove 22 is inclined, and the distance between the receiving groove 22 and the conductive sheet 12 gradually decreases along the width direction of the extension sheet 2. The receiving groove 21 is inclined, wherein the inclination direction of the receiving groove 21 is the same as the inclination direction of the receiving groove 22.

[0031] Reference Figure 3 A rotating rod 23 is fixedly connected to the wall of the receiving groove 21, and a mounting rod 231 is fixedly connected to the rotating rod 23. The mounting rod 231 can be completely located within the receiving groove 21. A stop block 232 is fixedly connected to the rotating rod 23, and the stop block 232 can pass through the receiving hole 221 and be inserted into the receiving groove 22. A stop groove 233 is formed on the surface of the stop block 232.

[0032] Reference Figure 3 A mounting gear 234 is fixedly connected to the rotating rod 23. The mounting gear 234 and the stop block 232 are located at different ends of the rotating rod 23. A stop strip 235 is slidably connected within the receiving groove 22. The stop strip 235 can slide along the length of the receiving groove 22, and can be inserted into the stop groove 233. The stop strip 235 and the mounting gear 234 mesh with each other.

[0033] Reference Figure 3 When the rotating rod 23 rotates, the rotating rod 23 drives the stop strip 235 to slide through the mounting gear 234, so that the stop strip 235 is inserted into the stop groove 233, thereby limiting the adjacent mounting rods 231 and preventing all the mounting rods 231 in the same row from falling over at once due to wind or other external factors.

[0034] Reference Figure 3 When the mounting rod 231 is fully inside the receiving groove 21, the mounting rod 231 drives the mounting gear 234 to rotate, and the mounting gear 234 drives the stop strip 235 to move, allowing the stop strip 235 to disengage from the stop groove 233. The stop strip 235 unlocks the next mounting rod 231 so that the wire can continue to drive the next mounting rod 231 to rotate.

[0035] Reference Figure 3 A torsion spring 236 is fixedly connected to the rotating rod 23. The torsion spring 236 is used to drive the stop block 232 to rotate, that is, the torsion spring 236 is used to drive the mounting rod 231 to be perpendicular to the extension piece 2.

[0036] Reference Figure 4A fixing groove 25 is formed on the outer surface of the mounting rod 231 closest to the conductive sheet 12. A fixing spring 251 is fixedly connected to the bottom wall of the fixing groove 25, and a fixing piece 252 is fixedly connected to the surface of the fixing spring 251 away from the bottom wall of the fixing groove 25. The fixing spring 251 drives the fixing piece 252 to disengage from the fixing groove 25. When the fixing piece 252 disengages from the fixing groove 25, the fixing spring 251 is in a compressed state.

[0037] Reference Figure 2 and Figure 4 An extension strip 253 is fixedly connected to the surface of the extension piece 2, and the extension strip 253 is located on the side of the mounting rod 231 closest to the conductive piece 12. The wire passes around the mounting rod 231 closest to the conductive piece 12, and the wire is located between the fixed piece 252 and the extension strip 253, which enhances the stability of the connection between the wire and the conductive piece 12.

[0038] Reference Figure 3 Except for the mounting rod 231 with the fixed groove 25, all other mounting rods 231 have mounting blocks 24 fixedly connected to their outer surfaces. The mounting blocks 24 are located on the side of the mounting rod 231 away from the rotating rod 23. A mounting spring 241 is fixedly connected to the mounting block 24, and the mounting spring 241 can deform in the direction of the mounting rod 231.

[0039] Reference Figure 3 The wire passes around the mounting rod 231 and can be located between the mounting spring 241 and the mounting rod 231. The wire is located on the side of the mounting block 24 facing the extension piece 2, so that the mounting block 24, the mounting spring 241 and the mounting rod 231 can position the wire, reducing the possibility of the wire coming off the mounting rod 231. The wire can also slide on the mounting rod 231 to provide a design that allows for pulling.

[0040] The implementation principle of a voltage transformer in this application embodiment is as follows: the operator first installs the wire on the conductive sheet 12, then the operator moves the installation spring 241 so that the wire is wound between the installation rod 231 and the installation spring 241, and then the operator allows the installation rod 231 to be wound on the two sets of installation rods 231 respectively.
