Description

Technical Field

[0001] The invention relates to the technical field of voltage transformers, and in particular to a voltage transformer that is easy to install. Background Art

[0002] A voltage transformer is similar to a transformer, and is an instrument used to transform voltage. It also has two windings, one called the primary winding and the other called the secondary winding. Both windings are mounted on or wound around the iron core, and there is insulation between the two windings and between the windings and the iron core, so that there is electrical isolation between the two windings and between the windings and the iron core. When the voltage transformer is in operation, the primary winding is connected in parallel to the high-voltage line, and the secondary winding is connected in parallel to the instrument or relay. Therefore, when measuring the voltage on the high-voltage line, although the primary voltage is very high, the secondary voltage is low, which can ensure the safety of the operator and the instrument.

[0003] The principle of the voltage transformer is to introduce the voltage through the primary side, and then reduce the voltage ratio through the transformer and transmit it to the secondary side. If the primary side voltage is overloaded or too high, it will cause the primary side winding to overload and heat up, thus affecting the safety of the entire equipment. Although disconnecting the secondary side can also reduce the load, it cannot eliminate the risk of excessive current on the primary side. Disconnecting the primary side can cut off the source of overload current and protect the equipment from further damage in time. Therefore, in order to ensure the safety and normal operation of the voltage transformer, the primary side should be disconnected first when overload and heating occur.

[0004] Chinese patent CN109545513B discloses a pressure relief type anti-oil leakage protection capacitor voltage transformer device, whose structure includes: an oil tank composite body, a lower capacitor voltage divider, a terminal board, a supporting main rod, an upper capacitor voltage divider, an electromagnetic unit, and an output wiring slot. The oil tank composite body is installed below the electromagnetic unit and buckled with the electromagnetic unit. An output wiring slot is provided below the electromagnetic unit and is electrically connected to the output wiring slot. When the device is in use, the oil tank composite mechanism is provided to enable the present invention to avoid the situation that when the magnetic flow on the transformer is uneven, the high temperature causes the sealing ring in the oil tank to gradually age, causing the oil tank shell to expand and leak oil, affecting the normal operation of the transformer, and when the current of the electromagnetic ring is too large, it is easy to cause the transformer to heat up, thereby greatly reducing the voltage and causing damage to the device, so that the device can effectively prevent the occurrence of oil leakage and the structural safety of the transformer.

[0005] The above-mentioned patented capacitive voltage transformer grounds the excess current to avoid the problem of the transformer tube being damaged by overheating due to excessive current. However, this method is not applicable to electromagnetic voltage transformers. At the same time, due to their heavy weight, the voltage transformer is inconvenient to install in some special occasions. Therefore, the inconvenient installation and overload heating of the voltage transformer become the primary problems that need to be solved in actual use. Summary of the invention

[0015] Preferably, a protective door is installed on one side of the adjustment box.

[0016] Preferably, a terminal post is provided on the mounting seat located on one side of the housing.

[0017] Compared with the prior art, the present invention has the following beneficial effects: (1) The overheat protection component provided in the present invention, when the voltage transformer is overloaded and heated, the first terminal, the second terminal and the coil winding structure will all overheat, and the metal connector connected to the second terminal will be connected to the second terminal. At this time, too much heat will be generated due to the passage of current. The closed container on the metal connector will evaporate the liquid in the closed container through heat conduction, and the gas will accumulate in the closed container, reducing the mass, so that the weight of the closed container end is lower than the weight of the other end. Based on the lever principle, the metal connector in the second terminal cover is driven to rotate upward around the rotating drum and detach from the second terminal. At the same time, the permanent magnet and the adjacent metal connector are quickly connected due to the mutual attraction relationship, forming a closed container end circuit state, which can effectively cut off the power supply and prevent excessive current from continuing. The liquid continues to flow into the voltage transformer, causing damage to the voltage transformer, thereby preventing the voltage transformer from overheating and running away from control and causing an accident. At this time, the metal connector at the other end is connected to the metal connector at a faster speed due to the permanent magnet in the socket, so that a loop is formed between the power supply, the buzzer, the socket and the metal connector. The buzzer sounds to remind the staff to repair it in time, reducing the hidden danger of accidents caused by long-term non-monitoring of the high-voltage circuit due to equipment failure. Furthermore, the metal connector at one end of the closed container gradually cools down after it is separated from the second terminal. At this time, the liquid in the closed container cools down, and the gravity increases under the cooling effect. The permanent magnet is set so that the metal connector and the second terminal will not be connected again before the equipment is repaired, and no secondary accident will occur, thereby effectively ensuring the equipment installation of the voltage transformer.

[0018] (2) When installing the installation assembly of the present invention, align the installation seat with the place where it is required to be installed, insert the outer cylinder on the installation seat into the through hole of the installation position, and then insert the inner cylinder into the outer cylinder. At this time, the teeth on the extension column at the bottom of the inner cylinder mesh with the teeth on the abutment column at the bottom of the outer cylinder. During the insertion process, the abutment column is driven to engage in a horizontal state, and the end of the abutment column away from the extension column abuts against the bottom of the installation position, and the inner cylinder and the outer cylinder are fastened by a fastener, completing the installation of the voltage transformer. At the same time, when disassembly is required, it is only necessary to rotate the inner cylinder through the handheld end. When the inner cylinder rotates, the fastening rods on both sides slide along the groove. When sliding, the fastening rods gradually squeeze the spring inward, and finally the fastening rods are separated from the groove, so that the limit between the inner cylinder and the outer cylinder can be released and disassembly can be carried out. During the whole process, only insertion is required for installation, and rotation is required for disassembly. The installation is convenient and quick. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The preferred embodiments of the present invention are described below in conjunction with the drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention. In addition, the embodiments of the present invention and the features in the embodiments may be combined with each other if there is no conflict. Example

Both windings are mounted on or wound on an iron core. There is insulation between the two windings and between the winding and the iron core, so that there is electrical isolation between the two windings and between the winding and the iron core. When the voltage transformer is in operation, the primary winding is connected in parallel to the high-voltage line, that is, the primary winding is connected to the high-voltage line through the insulator guards 130 on both sides after being connected to the first terminal 410 and the second terminal 420 of the present invention. The secondary winding is connected in parallel to the instrument or relay, and the secondary winding is connected to the instrument or relay through the junction box provided by the present invention; The second terminal 420 is bent, and a notch is provided in the middle of the second terminal 420; an overheat protection component 500 is connected between the second terminal 420 and the adjustment box 150; a mounting seat 200 is provided at the bottom of the shell 100, and mounting components 300 are provided on the four corners of the mounting seat 200.

[0023] The mounting assembly 300 is used for fixing and mounting the voltage transformer. The overheat protection assembly 500 cuts off the power supply when the voltage transformer is overloaded, so as to prevent excessive current from continuing to flow into the voltage transformer and causing damage to the voltage transformer.

[0024] In this embodiment, the mounting assembly 300 includes an outer cylinder 310 fixed on the mounting seat 200, and an inner cylinder 320 mounted in the outer cylinder 310; a positioning seat 311 is provided on the top of the outer cylinder 310, a positioning ring 313 is provided below the outer cylinder 310, and the bottom of the outer cylinder 310 is fixedly connected to the positioning ring 313 by a plurality of evenly distributed connecting legs 312; a plurality of abutment columns 314 are rotatably connected to the positioning ring 313, and the plurality of abutment columns 314 and the connecting legs 312 are evenly spaced in sequence; the abutment column 314 located at one end of the positioning ring 313 is in an arc shape, and a tooth 315 is provided on the surface; a hand-held portion 321 is provided on the top of the inner cylinder 320, and an extension column 322 is provided at the bottom of the inner cylinder, and a tooth pattern 323 is provided on the extension column 322, and the tooth 315 and the tooth pattern 323 are meshed with each other; a buckle 330 is also provided between the outer cylinder 310 and the inner cylinder 320.

[0025] A positioning seat 311 is provided on the top of the outer cylinder 310, which can be fixed to the mounting seat 200 by bolts, pins and other components, which are not limited here; the positioning ring 313 provided at the bottom of the outer cylinder 310 is used to install the abutment column 314. During installation, the extension column 322 at the bottom of the inner cylinder 320 is inserted into the abutment column 314, and the engagement between the teeth 315 and the tooth pattern 323 drives the abutment column 314 to rotate from vertical to outward to horizontal setting. At this time, the end of the horizontally set abutment column 314 away from the extension column 322 abuts against the bottom of the mounting plate at the installation position, thereby achieving a fixed connection between the mounting seat 200 and the mounting plate; at the same time, after being installed in place, the outer cylinder 310 and the inner cylinder 320 are fixedly connected by the buckle 330, so that the mounting seat 200 is firmly connected to the mounting plate.

[0026] In this embodiment, the fastening component 330 includes a groove 331 symmetrically opened on the inner wall of the outer cylinder 310, and a through hole 332 opened on the inner cylinder 320, a spring 333 is installed in the middle of the through hole 332, and the two ends of the spring 333 are abutted with a fastening rod 334, and the end of the fastening rod 334 abutting against the spring 333 is limited in the through hole 332; the end of the fastening rod 334 located on the outside of the through hole 332 is fastened in the groove 331.

[0027] Specifically, the buckling of the buckle 330 is that when the inner cylinder 320 is inserted into the outer cylinder 310, the buckling rods 334 on both sides of the inner cylinder 320 are compressed by the springs 333 and retracted into the through holes 332 of the inner cylinder 320. When the buckling rods 334 reach the grooves 331, the buckling rods 334 are rapidly opened under the action of the springs 333 and abut against the grooves. At this time, the end of the abutting column 314 away from the extension column 322 abuts against the bottom of the mounting plate at the mounting position, thereby achieving a fixed connection between the mounting seat 200 and the mounting plate. When replacing or repairing the voltage transformer, the inner cylinder 320 can be rotated by the hand-held part 321. During the rotation, the abutment column 314 slides along the bottom of the groove 331 and is gradually compressed into the through hole 332 under the action of the spring 333. At this time, the groove 331 is rotated out and the inner cylinder 320 can be taken out upward. At the same time, the limit of the bottom of the mounting plate by the abutment column 314 is cancelled to realize the disassembly function. During the entire installation process, the installation component only needs to be inserted for installation, and disassembly only needs to be rotated for disassembly. The installation is convenient and quick.

[0028] In this embodiment, the groove 331 is a crescent-shaped groove, the bottom surface of the groove 331 is arc-shaped, and the end of the buckling rod 334 located outside the through hole 332 is hemispherical.

[0029] In this embodiment, the outer diameter of the positioning ring 313 is smaller than the inner diameter of the outer cylinder 310 .

[0030] In this embodiment, the overheating protection component 500 includes a support frame 510 arranged in the adjustment box 150, and a rotating drum 520 is rotatably connected to the support frame 510, and connecting plates 530 are symmetrically fixed at both ends of the rotating drum 520, and a metal connecting piece 540 is fixed at one end of the two connecting plates 530 away from the rotating drum 520; the connecting plate 530 at one end of the rotating drum 520 penetrates into the second wiring cover 120, and the metal connecting piece 540 located in the second wiring cover 120 can be overlapped and connected with the interface of the second terminal 420, and the metal connecting piece 540 at the other end of the rotating drum 520 can be overlapped and connected with the socket 550, and the socket 550 is installed in the adjustment box 150; a sealed container 560 is fixedly installed on the metal connecting piece 540 located in the second wiring cover 120, and the sealed container 560 contains a solution.

[0031] The rotating drum 520 is rotatably connected to the support frame 510, and the connecting plates 530 arranged on both sides of the rotation are symmetrically arranged, thereby forming a lever. When installing, the sealed container 560 containing liquid is fixedly installed on the metal connecting piece 540 in the second wiring cover 120. After the installation is completed, it should be noted that the connecting plate 530 at one end of the second wiring cover 120 is slightly heavier than the other end. At this time, the metal connecting piece 540 in the second wiring cover 120 overlaps the notch of the second terminal 420, so that the metal connecting piece is connected to the second terminal 420 to conduct current; When the voltage transformer is overloaded and heated, the first terminal 410, the second terminal 420 and the coil winding structure 400 will all overheat. The metal connector 540 connected to the second terminal 420 is connected to the second terminal 420, and overheating will also occur at this time. The closed container 560 on the metal connector 540 evaporates the liquid in the closed container 560 through heat conduction, and the gas accumulates in the closed container 560, reducing the weight, so that the weight of the closed container 560 end is lower than the weight of the other end. Based on the lever principle, the metal connector 540 in the second terminal cover 120 is driven to rotate upward around the rotating drum 520 and disengage from the second terminal 420. At the same time, the permanent magnet and the adjacent metal connector 540 are quickly connected due to the mutual attraction relationship, forming a circuit-breaking state at the closed container end. The circuit-breaking state can effectively cut off the power supply and prevent excessive current from continuing to flow into the voltage transformer.

[0032] It should be noted that the boiling point of the selected liquid needs to be close to the temperature generated when the voltage transformer is overloaded, to ensure that it begins to evaporate quickly when overloaded, thereby achieving the function of circuit breaking to form overheat protection.

[0033] In this embodiment, a permanent magnet is fixed inside the socket 550 .

[0034] In this embodiment, the overheat protection component 500 further includes a power supply 580 and a buzzer 570 , and the socket 550 , the power supply 580 and the buzzer 570 are electrically connected in sequence.

[0035] By setting the permanent magnet, after the power is cut off, the connection between the socket 550 and the metal connector 540 in the adjustment box 150 is accelerated through attraction, so that a loop is formed between the power supply 580, the buzzer 570, the socket 550 and the metal connector 540, and the buzzer 570 buzzes to remind the staff to repair in time; further, the metal connector 540 at one end of the sealed container 560 gradually cools down after being separated from the second terminal 420. At this time, the liquid in the sealed container 560 is cooled, and the gravity increases under the cooling effect. The setting of the permanent magnet prevents the metal connector 540 from being connected to the second terminal 420 again before the equipment is repaired, thereby effectively ensuring the equipment installation of the voltage transformer.

[0036] In this embodiment, a protective door is installed on one side of the adjustment box 150 .

[0037] In this embodiment, a junction box is provided on a mounting seat located on one side of the housing 100 .

[0038] The working principle of a voltage transformer that is easy to install in the present invention is as follows: During installation, align the mounting base 200 with the location where it needs to be installed, insert the outer cylinder 310 on the mounting base 200 into the through hole at the installation location, insert the extension column 322 at the bottom of the inner cylinder 320 into the abutment column 314, and drive the plurality of abutment columns 314 to rotate from vertical to outward to horizontal arrangement through the engagement between the teeth 315 and the tooth pattern 323. At this time, the end of the horizontally arranged abutment column 314 away from the extension column 322 abuts against the bottom of the mounting plate at the installation location, thereby achieving the goal of connecting the mounting base 200 with the mounting base 200. When the inner cylinder 320 is inserted into the outer cylinder 310, the buckling rods 334 on both sides of the inner cylinder 320 are compressed by the springs 333 and retracted into the through holes 332 of the inner cylinder 320. When the buckling rods 334 reach the grooves 331, the buckling rods 334 are rapidly opened under the action of the springs 333 and abut against the grooves 331. At this time, the end of the abutting column 314 away from the extension column 322 abuts against the bottom of the mounting plate at the mounting position, thereby achieving a fixed connection between the mounting seat 200 and the mounting plate. When the voltage transformer needs to be replaced or repaired, the inner cylinder 320 can be rotated by the handheld part 321. During the rotation, the abutment column 314 slides along the bottom of the groove 331 and is gradually compressed into the through hole 332 under the action of the spring 333. At this time, the groove 331 is rotated out and the inner cylinder 320 can be taken out upward. At the same time, the abutment column 314 cancels the limit of the bottom of the mounting plate, thereby realizing the disassembly function. When the voltage transformer is overloaded and heated, the first terminal 410, the second terminal 420 and the coil winding structure 400 will all overheat. The metal connector 540 connected to the second terminal 420 is connected to the circuit, and too much heat will be generated at this time. The closed container 560 on the metal connector 540 evaporates the liquid in the closed container 560 through heat conduction, and the gas is accumulated in the closed container 560, and the mass is reduced, so that the weight of the closed container 560 end is lower than the weight of the other end. Based on the lever principle, the metal connector 540 in the second wiring cover 120 is driven to rotate around the rotating drum 520 and rotate upward, and detach from the second terminal 420. At the same time, the permanent magnet and the adjacent metal connector 420 are quickly connected due to the mutual attraction relationship, forming a closed container end The circuit state is formed, and the circuit state is formed, which can effectively cut off the power supply and prevent excessive current from continuing to flow into the voltage transformer; After the circuit is disconnected, the attraction between the permanent magnet and the metal connector 540 accelerates the connection between the socket 550 and the metal connector 540 in the adjustment box 150, so that a loop is formed between the power supply 580, the buzzer 570, the socket 550 and the metal connector 540, and the buzzer 570 sounds to remind the staff to repair in time; further, the metal connector 540 at one end of the sealed container 560 gradually cools down after being separated from the second terminal 420. At this time, the liquid in the sealed container 560 cools down, and the gravity increases under the cooling effect. The setting of the permanent magnet prevents the metal connector 540 from being connected to the second terminal 420 again before the equipment is repaired, thereby effectively ensuring the equipment installation of the voltage transformer.
