Description

Technical Field

[0001] This invention relates to the field of transformer technology, and in particular to a transformer winding and transformer for suppressing inter-butterfly potential difference. Background Technology

[0002] Transformer windings refer to the circuit part of a transformer, made of copper or aluminum wires with high conductivity, and are used in power systems. The windings should have sufficient insulation strength, mechanical strength, and heat resistance.

[0003] Windings are generally classified into two types: layered and disc-shaped. A layered winding is one in which the turns of the winding are arranged continuously along its axial direction. Each layer of a layered winding is typically cylindrical; therefore, a winding consisting of two layers is called a double-layered cylindrical winding, and one consisting of multiple layers is called a multi-layered cylindrical winding.

[0004] The pancake winding, also known as the interleaved winding, consists of several coils of high-voltage and low-voltage windings arranged alternately along the height of the core column. For ease of insulation, the low-voltage windings are typically placed on the top and bottom layers, as shown in the diagram. The main advantages of the interleaved winding are low leakage reactance, high mechanical strength, and convenient lead-in. This winding type is mainly used in low-voltage, high-current transformers, such as large-capacity electric furnace transformers and resistance welding machine (such as spot welding, roll welding, and butt welding machine) transformers.

[0005] A lightning surge is a non-periodic voltage pulse with a large amplitude and a short duration. This surge propagates along the transmission line from the point of lightning strike at the speed of light to both ends. When this surge reaches the transformer, the voltage on the transformer leads rises rapidly, equivalent to applying a voltage with a very high frequency and amplitude. This voltage applied to the transformer's longitudinal insulation can be tens or even hundreds of times higher than the normal power frequency voltage. In the initial instant, the voltage of the first few turns near the winding head rises very high, even reaching 50 to 200 times that of the rated voltage operation, which can easily cause insulation breakdown at the winding head.

[0006] Traditional disc windings are divided into intertwined windings and continuous windings. Compared to continuous windings, intertwined windings have the advantages of higher mechanical strength and better heat dissipation, but also a larger potential difference between turns and between discs. However, due to the larger potential difference between discs in intertwined windings, they are more susceptible to breakdown discharge under lightning strikes. Summary of the Invention

[0007] Therefore, it is necessary to provide a transformer winding and transformer that suppresses the potential difference between winding discs, in order to address the problem that the winding discs of the entangled structure are prone to breakdown discharge under lightning strikes.

[0010] The second branch plate includes a second tangled section and a second continuous section that are interconnected, and both the second tangled section and the second continuous section include multiple turns of wire.

[0011] Wherein, the number of adjacent turns in the first continuous segment and the second continuous segment are continuous; the first tangled segment is connected to the second tangled segment, and the number of adjacent turns in the first tangled segment and the second tangled segment are not continuous.

[0012] In one embodiment, the difference between adjacent turns of the first continuous segment and the second continuous segment is 1 turn.

[0013] In one embodiment, the first tap plate and the second tap plate are each wound with 12 turns of wire.

[0014] In one embodiment, the number of turns in the first tangled segment is 17, 7, 16, 6, 15, 5, 14, 4, and 13, respectively, and the number of turns in the first continuous segment is 3, 2, and 1, respectively.

[0015] The number of turns in the second tangled segment is 8, 18, 9, 19, 10, 20, 11, 21, and 12 turns, respectively, and the number of turns in the second continuous segment is 22, 23, and 24 turns, respectively.

[0016] In one embodiment, the number of turns in the first tangled segment is 16, 8, 15, 7, 14, 6, and 13, respectively, and the number of turns in the first continuous segment is 5, 4, 3, 2, and 1, respectively.

[0017] The number of turns in the second tangled section is 9, 17, 10, 18, 11, 19, and 12 turns, respectively, and the number of turns in the second continuous section is 20, 21, 22, 23, and 24 turns, respectively.

[0018] In one embodiment, the number of turns in the first tangled segment is 15 turns, 9 turns, 14 turns, 8 turns, and 13 turns, respectively, and the number of turns in the first continuous segment is 7 turns, 6 turns, 5 turns, 4 turns, 3 turns, 2 turns, and 1 turn, respectively.

[0019] The number of turns in the second tangled section is 10, 16, 11, 17, and 12, respectively, and the number of turns in the second continuous section is 18, 19, 20, 21, 12, 23, and 24, respectively.

[0020] In one embodiment, the number of turns in the first tangled segment is 14 turns, 10 turns, and 13 turns, respectively, and the number of turns in the first continuous segment is 9 turns, 8 turns, 7 turns, 6 turns, 5 turns, 4 turns, 3 turns, 2 turns, and 1 turn, respectively.

[0021] The number of turns in the second tangled section is 11, 15, and 12, respectively, and the number of turns in the second continuous section is 16, 17, 18, 19, 20, 21, 12, 23, and 24, respectively.

[0024] A transformer comprising a transformer winding for suppressing inter-panel potential difference as described in any of the preceding claims.

[0025] The aforementioned transformer winding for suppressing inter-winding potential difference reduces the number of intertwined turns in existing windings with a twisted structure. These reduced turns are then connected in series with an equivalent continuous winding, creating a semi-twisted winding. By reducing the number of intertwined turns, the inter-winding potential difference in twisted windings is effectively suppressed. Compared to traditional methods for improving the inter-winding potential difference distribution in twisted windings, this transformer winding effectively suppresses the inter-winding potential difference under lightning strikes, improving insulation reliability and significantly reducing the risk of breakdown accidents caused by large inter-winding potential differences in transformers with twisted winding structures under lightning strikes. Furthermore, the installation and operation of this transformer winding for suppressing inter-winding potential difference are simple, requiring minimal labor costs and thus not increasing the production cost of the transformer winding.

[0026] By installing transformer windings that suppress inter-disk potential difference, the transformer's ability to withstand lightning strikes can be greatly improved, thereby extending its service life. Attached Figure Description

[0040] Overview of the main line of invention:

[0041] To reduce the oscillating voltage of transformer windings under lightning strikes, two common approaches are used. One approach employs a twisted structure, increasing the energy storage of the capacitance between the turns by varying the arrangement of the coils, thus increasing the equivalent series capacitance of the winding coils. The other approach uses an internally shielded structure, inserting coils that are not electrically connected to the working turns and do not carry current under normal operation but do under impulse voltage. This increases the equivalent capacitance of the winding coils through the capacitance difference between the working and shielding coils. For the internally shielded structure, the shielding depth and method are easily modified, allowing for easy arrangement of the windings according to capacitance partitioning requirements, dividing the entire winding into several sections with different longitudinal capacitances, resulting in a more uniform distribution of impulse voltage along the winding. For the twisted structure, because the equivalent series capacitance is much larger than that of the continuous structure, the effect of capacitance partitioning in improving impulse voltage distribution is poor, and the oscillation potential of the coils at the transition between the twisted and continuous sections is very high.

[0042] For windings with a twisted structure, traditional methods for improving the inter-winding potential distribution are limited. Common approaches include: 1. Enlarging the oil channels between windings or thickening the turns of insulation to improve insulation reliability, depending on the potential distribution under lightning strikes; 2. Increasing the number of twisted segments to reduce the overall winding's oscillation potential and thus reduce the inter-winding potential difference. However, these methods are either ineffective or require significant additional labor costs. Therefore, a relatively simple and cost-free method is needed to improve the inter-winding potential difference in transformers with twisted structures, addressing the risk of breakdown accidents due to large inter-winding potential differences under lightning strikes.

[0043] Specifically, when the waveform and amplitude of the transformer winding input voltage are constant, the amplitude of the free oscillation voltage inside the winding mainly depends on the difference between the final voltage distribution and the initial voltage distribution of the transformer winding. Improving the initial voltage distribution to make it as close as possible to the final voltage distribution is the main method to reduce the amplitude of the free oscillation voltage. The initial voltage distribution formula is:

[0048]

[0049] The equivalent series capacitance K of a single-strand entangled winding unit consisting of two twisted wires is given.

[0050]

[0051] The equivalent series capacitance K of a single unit of a semi-entangled winding structure with two coils is given.

[0052]

[0053] As can be seen from the above, when a single-strand semi-entangled structure is used as a transition structure between a single-strand entangled structure and a continuous structure, the capacitance change of the transition section can be reduced, thereby suppressing the potential difference between the winding discs.

[0054] Based on this, see Figures 1 to 4An embodiment of the present invention provides a transformer winding for suppressing the potential difference between the taps, comprising: a first tap 10 and a second tap 20.

[0055] The first branch junction 10 includes a first tangled segment 11 and a first continuous segment 12 that are interconnected, and both the first tangled segment 11 and the first continuous segment 12 include multiple turns of wire. The second branch junction 20 includes a second tangled segment 21 and a second continuous segment that are interconnected, and both the second tangled segment 21 and the second continuous segment 22 include multiple turns of wire.

[0056] In this case, the number of adjacent turns of the wire turns in the first continuous segment 12 and the number of adjacent turns in the second continuous segment 22 are continuous. The number of consecutive turns means that the difference between adjacent turns in the first continuous segment 12 and the second continuous segment 22 is 1 turn. In other words, the wire turns in the first continuous segment 12 and the second continuous segment 22 are continuously connected in series to form a continuous winding.

[0057] Furthermore, the first entangled segment 11 is connected to the second entangled segment 21, and the number of adjacent turns in the first entangled segment 11 and the second entangled segment 21 is discontinuous. The discontinuous number of adjacent turns means that two adjacent turns in the first entangled segment 11 and the second entangled segment 21 are not directly connected, but are connected in series after a few turns. In other words, the turns in the first entangled segment 11 and the second entangled segment 21 are intertwined to form an entangled winding.

[0058] The aforementioned transformer winding for suppressing inter-winding potential difference reduces the number of intertwined turns in existing windings with a twisted structure. These reduced turns are then connected in series with an equivalent continuous winding, creating a semi-twisted winding. By reducing the number of intertwined turns, the inter-winding potential difference in twisted windings is effectively suppressed. Compared to traditional methods for improving the inter-winding potential difference distribution in twisted windings, this transformer winding effectively suppresses the inter-winding potential difference under lightning strikes, improving insulation reliability and significantly reducing the risk of breakdown accidents caused by large inter-winding potential differences in transformers with twisted winding structures under lightning strikes. Furthermore, the installation and operation of this transformer winding for suppressing inter-winding potential difference are simple, requiring minimal labor costs and thus not increasing the production cost of the transformer winding.

[0059] In embodiments of the present invention, the transformer winding for suppressing inter-panel potential difference further includes a shunting line 32. The first continuous segment 12 and the second continuous segment 22 are connected by the shunting line 32, and the first entangled segment 11 and the second entangled segment 21 are connected by the shunting line 32, so as to form an entangled winding through the first entangled segment 11 and the second entangled segment 21.

[0060] In embodiments of the present invention, the transformer winding for suppressing inter-panel potential difference further includes lead wire 30 and connecting wire 31 for connecting to external electrical appliances. Lead wire 30 is connected to the first continuous segment 12, and connecting wire 31 is connected to the second continuous segment 22.

[0061] In an embodiment of the present invention, the first tap sheet 10 and the second tap sheet 20 are each wound with 12 turns of wire. By adjusting the number of turns in the first entanglement section 11 and the second entanglement section 21 of the 12 turns of wire, the equivalent series capacitance on the first tap sheet 10 and the second tap sheet 20 can be adjusted, thereby making the series capacitance of the winding formed by the first tap sheet 10 and the second tap sheet 20 change more slowly, thus effectively suppressing the potential difference between the tap sheets of the entangled winding.

The second continuous segment 22 has 16, 17, 18, 19, 20, 21, 12, 23, and 24 turns respectively. The 10th and 11th turns, the 14th and 15th turns, and the 13th and 12th turns are connected by a aligning line 32. The lead-out line 30 is connected to the 1st turn, and the connecting line 31 is connected to the 24th turn.

[0068] Based on existing windings with a twisted structure, the number of twisted turns in the twisted winding is reduced.
