Description

Technical Field

[0001] This invention belongs to the field of marine power system technology, specifically relating to an ampere-turn adjuster and adjustment method for rapid fine-tuning of ampere-turns. Background Technology

[0002] Magnetic stealth is a crucial component of ship stealth, achieved through the ship's degaussing system. Enhancing a ship's magnetic stealth can effectively defend against magnetic mine attacks. A ship's degaussing system typically consists of a degaussing winding, an ampere-turn regulator, a power supply, and other auxiliary equipment. When direct current is passed through the degaussing winding, a winding magnetic field is generated. The amplitude of the winding magnetic field is changed by altering the number of turns, and the direction of the winding magnetic field is changed by altering the direction of the direct current. This results in a degaussing winding magnetic field with the same amplitude but opposite direction to the ship's induced magnetic field, effectively counteracting the ship's induced magnetic field.

[0003] Ampere-turn regulators are used to connect the demagnetizing windings in various sections and adjust the ampere-turns of the winding by changing the number of turns (i.e., the number of reversed turns). Currently, ampere-turn regulators can achieve the reverse connection of 1 turn or more turns through the electrical connection module in the middle of the regulator (commonly known as coarse adjustment), while the reverse connection of less than 1 turn is achieved by reversing the multi-core wire, which is usually referred to as "ampere-turn fine adjustment".

[0004] When fine-tuning the ampere-turns of this type of ampere-turn adjuster, it is necessary to disconnect the terminals of each core of the multi-core demagnetizing cable, swap the positive and negative terminals, and then reconnect them. This changes the wiring inside the enclosure, resulting in a large amount of rewiring work, time-consuming operation, and a high risk of errors. Summary of the Invention

[0005] The technical problem to be solved by this invention is to provide an ampere-turn adjuster and adjustment method for rapid fine-tuning of ampere-turns, used for... The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows: an ampere-turn adjuster for rapid fine-tuning of ampere-turns, comprising multiple sets of double-throw switches and a switch board, used to rapidly fine-tune the ampere-turns of the demagnetizing winding of the ship's demagnetizing system by selecting the positive and negative connection of the demagnetizing cable; when the double-throw switch is switched to the positive connection, the positive and negative terminals of the demagnetizing cable core are connected to the positive and negative terminals of the power supply, respectively; when the double-throw switch is switched to the reverse connection, the original positive and negative terminals of the cable core are connected to the negative and positive terminals of the power supply, respectively, and the polarity is reversed from the original state.

[0006] According to the above scheme, different specifications of ampere-turn regulators are formed according to the different rated currents of the demagnetizing windings, including 40A and 80A ampere-turn regulators.

[0007] Furthermore, the 40A ampere-turn regulator includes 7 pairs of demagnetizing cable terminals, 7 double-throw switches, and 1 pair of power input / output terminals; the corresponding multi-core demagnetizing cable has 7 cores, and the cores are connected in parallel to carry a total current of 40A; each core corresponds to a 10A double-throw switch with 6 terminals, which is used to quickly fine-tune the ampere-turns by reversing the connection of each core of the multi-core demagnetizing cable.

[0008] Furthermore, on the left side of the 40A ampere-turn regulator are the terminals for each core of the demagnetizing cable. Terminals 1 to 7 are connected to the positive terminals of cores 1 to 7, and terminals 1' to 7' are connected to the negative terminals of cores 1 to 7. On the right side of the switch panel are seven double-throw switches, each corresponding to a pair of terminals on the left. The (+1) and (-1) terminals at the top and bottom of the panel are the positive and negative terminals of the 40A ampere-turn regulator, used for connecting an external DC power supply.

[0009] Furthermore, the 80A ampere-turn regulator includes 7 pairs of demagnetizing cable terminals, 7 double-throw switches, 1 switch board, and 1 pair of power input / output terminals; the corresponding multi-core demagnetizing cable has 14 cores; the cores are connected in parallel and share a current of 80A; each of the 1st to 7th cores corresponds to a 10A double-throw switch with 6 terminals, which is used to reverse the connection of the 1st to 7th cores of the multi-core demagnetizing cable; the 8th to 14th cores are reversed through the switch board; the combination of the two is used to reverse the connection of any number of cores of 14 or less, achieving rapid fine-tuning of the ampere-turns.

[0010] Furthermore, the switchboard of the 80A specification ampere-turn regulator includes terminal pairs (8) / (8'), (+A) / (-A) and (0) / (0'); the (+1) / (-1) terminals are the positive and negative poles of the switchboard and are used to connect to an external DC power supply; the positive and negative poles of the multi-core 8~14 core wires are respectively crimped onto the (8) and (8') terminals; (0) to (-A) and (0') to (8') are the internal wires of the switchboard, and the (+1) to (+A) and (-1) to (-A) cables are the power supply wires of the switchboard; when connected in the correct direction, (+A) and (8), (0) and (0') are connected by a jumper; when connected in the reverse direction, the jumper is removed and the jumper is used to connect (8) and (0), (+A) and (0') respectively.

[0011] Furthermore, the upper part of the 80A ampere-turn regulator has 7 pairs of demagnetizing cable terminals and 7 double-throw switches corresponding to single-core wires, and the lower part has switch plates corresponding to cores 8 to 14; the (+1) and (-1) terminals at the top and bottom of the panel are the positive and negative terminals of the 80A ampere-turn regulator.

[0012] Furthermore, the double-throw switch reverses the connection of cores 1 to 7 of the multi-core demagnetizing cable, and the switch board reverses the connection of cores 8 to 14; the combination of the two is used to reverse the connection of any number of cores of 14 or less, so as to achieve rapid fine adjustment of ampere-turns.

[0013] A method for rapidly fine-tuning ampere-turns includes the following steps: S1: Calculate the adjustment amount of the ampere-turns of the demagnetizing winding, and determine the number of multi-core wires of the ampere-turn regulator that need to be reversed for a certain demagnetizing winding section; S2: Reverse connection operation for multi-core wires.

[0028] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0029] Example 1 This embodiment presents an ampere-turn adjuster for rapid fine-tuning of ampere-turns, comprising a toggle switch and a switch plate. It is used for rapid fine-tuning of the ampere-turns of the demagnetizing winding in a ship's demagnetizing system without altering the original wiring of the multi-core demagnetizing cable, thus offering rationality and operability. Different specifications of ampere-turn adjusters are developed according to the rated current of the connected demagnetizing winding.

[0030] The 40A ampere-turn regulator is a type of ampere-turn regulator with a rated current of 40A for connecting the demagnetizing winding. Its multi-core adjustment module includes 7 pairs of demagnetizing cable terminals, 7 toggle switches, and 1 pair of power input / output terminals, used to reverse the connection of each core of the multi-core demagnetizing cable to achieve rapid fine-tuning of the ampere-turns. The corresponding multi-core demagnetizing cable is generally 7-core, such as 7×1.5 or 7×2.5. The cores are connected in parallel, carrying a total current of 40A, with each core carrying approximately 5.72A.

[0031] For each core wire, select a 10A toggle switch with 6 terminals, providing both positive and reverse connection options. The toggle switch's shape is as follows: Figure 1 The principle is as follows Figure 2 As shown.

[0032] Turning the toggle switch to the left indicates positive connection; when positive, the positive and negative terminals of the demagnetizing cable core are connected to the positive and negative terminals of the power supply, respectively; when reversed, the original positive and negative terminals of the cable core are connected to the negative and positive terminals of the power supply, respectively, and the polarity is exactly the opposite of the original state; when reversed, it is not necessary to reverse the connection of the positive and negative terminals of the demagnetizing cable core.

[0033] At this time, the multi-core wire adjustment module layout of the 40A ampere-turn regulator is as follows: Figure 3 As shown. The left side of the panel contains the terminals for each core of the demagnetizing cable. Terminals 1-7 are connected to the positive terminals of cores 1-7, and terminals 1'-7' are connected to the negative terminals of cores 1-7. The right side of the panel contains seven toggle switches, each corresponding to a pair of terminals on the left. The (+1) and (-1) terminals at the top and bottom of the panel are the positive and negative terminals of the multi-core wire adjustment module, connected to an external DC power supply.

[0034] When reversing the connection of n (n=1,2,…,7) cores of a multi-core demagnetizing cable, simply flip the first n toggle switches to the right.

[0035] For the 80A specification ampere-turn regulator, its multi-core wire adjustment module includes 7 pairs of demagnetizing cable terminals, 7 toggle switches, 1 switch board, and 1 pair of power input and output terminals. The toggle switches are used to reverse the connection of the 1st to 7th cores of the multi-core demagnetizing cable, and the switch board is used to reverse the connection of the 8th to 14th cores. The combination of the two is used to reverse the connection of any number of cores of 14 or less, so as to achieve rapid fine adjustment of the ampere-turns.

[0036] An 80A ampere-turn regulator refers to a type of ampere-turn regulator whose connected demagnetizing winding has a rated current of 80A. The corresponding multi-core demagnetizing cable typically has 14 cores, such as 14×1.5 or 14×2.5. The cores are connected in parallel, sharing a common current of 80A, with each core carrying approximately 5.72A.

[0037] For the first 7 cores (cores 1-7) of the demagnetizing cable, each core should still be connected to a 10A toggle switch, as in the previous section. For cores 8-14, a switch board should be used, and cores 8-14 should be directly reversed. The principle of the switch board is as follows... Figure 4 , Figure 5 As shown.

[0038] The switch board has three pairs of terminals: (8) / (8'), (+A) / (-A) and (0) / (0'). The (+1) / (-1) terminals are the positive and negative terminals of the multi-core wire adjustment module and are connected to an external DC power supply. The positive and negative terminals of the 7 cores (8 to 14 cores) of the multi-core wire are respectively crimped onto terminals (8) and (8').

[0039] The dashed lines indicate the internal wiring of the multi-core adjustment module, all of which are 1×10. (0) to (-A) and (0') to (8') are the internal wiring of the switch board, and (+1) to (+A) and (-1) to (-A) are the power supply wires of the switch board.

[0040] When connected correctly, (+A) and (8), and (0) and (0') are connected via jumpers. When connected in reverse, remove the jumpers and connect (8) and (0), and (+A) and (0') with jumpers respectively. In this case, it is not necessary to change the original wiring of the multi-core cable (8-14 cores).

[0041] The layout of the multi-core wire adjustment module of the 80A ampere-turn regulator is as follows: Figure 6 As shown.

[0042] The adjustment module is characterized by having 7 pairs of demagnetizing cable terminals and 7 toggle switches in the upper part, corresponding to single-core wires, and a switch board corresponding to cores 8 to 14 in the lower part. The (+1) and (-1) terminals at the top and bottom of the panel are the positive and negative terminals of the multi-core wire adjustment module.

[0043] The toggle switch reverses the connection of cores 1-7 in a multi-core demagnetizing cable, while the switch board reverses the connection of cores 8-14. Combined, these two components allow for reversing the connection of any number of cores (14 or fewer), enabling rapid fine-tuning of the ampere-turns.

[0044] This embodiment does not require changing the original wiring of the multi-core demagnetizing cable, reducing the workload of wiring personnel, shortening the testing time of the demagnetizing system, and improving testing efficiency.

[0045] Example 2 The principle of this embodiment is the same as that of embodiment 1, except that this embodiment uses a 40A or 80A ampere-turn regulator with a multi-core wire adjustment module.

[0046] Figure 7 This is a 40A ampere-turn regulator using a multi-core wire adjustment module. The left side of the regulator's interior contains the coarse adjustment module (typically 16 groups for 40A), and the right side contains the multi-core wire adjustment module. Dimensions in the diagram are in mm.

[0047] Figure 8 This is an 80A ampere-turn regulator that uses a multi-core wire adjustment module. The left side of the regulator's interior contains the coarse adjustment module, typically set to 12 groups for 80A; the right side contains the multi-core wire adjustment module. Dimensions in the diagram are in mm.

[0048] The proposed solution is reasonable, highly feasible, simple and convenient to implement, and has significant effects.

[0049] Example 3 This embodiment implements a method for rapidly fine-tuning the ampere-turns based on the principle of the above-described device embodiment, specifically including the following steps: S1: First, perform the ampere-turn adjustment calculation of the demagnetizing winding to determine the number of multi-core wires of the ampere-turn adjuster that need to be reversed for a certain demagnetizing winding section; S2: Reverse connection operation for multi-core wires, the specific steps are as follows: For 40A and 80A ampere-turn regulators, reverse the connection of 1 to 7 cores and directly flip the toggle switch of the multi-core wire adjustment module to the right side of the ampere-turn regulator; For an 80A ampere-turn regulator, reverse the connection of pins 8 to 14, and it can be divided into a 7+n combination (n=1,2,…,7). First, reverse the connection of pins 7 (i.e. pins 8 to 14) on the multi-core adjustment module switch board. The specific operation is as follows: remove the jumper between (+A) and (8), (0) and (0'), and use it to connect (8) and (0), (+A) and (0') respectively; then turn the first n toggle switches corresponding to the single cores on the top of the module to the right side of the ampere-turn regulator in sequence.

[0050] It should be understood that the sequence number of each step in the above embodiments does not imply the order of execution. The execution order of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiments of this application.

[0051] This embodiment calculates the ampere-turns adjustment of the demagnetizing winding to determine the number of multi-core wires of the ampere-turn adjuster that need to be reversed for a certain demagnetizing winding section; by using a toggle switch and a switch board to reverse the multi-core wires, the function of quickly fine-tuning the ampere-turns of the demagnetizing winding of the ship's demagnetizing system is realized.
