Description

Technical Field

[0001] This utility model relates to the field of instrument transformer coil technology, specifically an instrument transformer coil for high-voltage power systems. Background Technology

[0002] Instrument transformers, also known as instrument transformers, are a general term encompassing current transformers and voltage transformers. They are primary devices that enable communication between primary and secondary electrical systems. Instrument transformers transform the high voltage and large current of the primary system into low voltage and small current for use by measuring instruments, relay protection devices, and automatic devices in the secondary system. They serve as both a connecting element and an isolating element between the primary and secondary systems in a power system.

[0003] The core function of traditional current transformers (CTs / PTs) is limited to the transformation and measurement of electrical parameters such as current and voltage, resulting in a fundamental limitation in their sensing capabilities. This prevents them from effectively monitoring the actual physical state of the transformer's core component—the high-voltage coil—during operation. Consequently, the current transformer can only generate an alarm when the fault has developed to a certain extent, leading to significant economic losses. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A transformer coil for a high-voltage power system includes a transformer mechanism, an isolation mechanism, and a detection mechanism. The transformer mechanism includes an iron core and a conductor wound around the outside of the iron core. The isolation mechanism includes a spiral spacer sleeved around the outside of the iron core, multiple ferrules clamped to one side of the spiral spacer, and an arc plate connecting the multiple ferrules. The detection mechanism includes an optical fiber sensor connected between the multiple ferrules, an optical fiber demodulator disposed on one side of the arc plate and wired to the optical fiber sensor, and a high-temperature resistant adhesive bonded between the ferrules and the optical fiber sensor.

[0007] By adopting the above technical solution, the fiber optic sensor detects the temperature and shape of the conductor, and the detection information is uploaded to the fiber optic demodulator. The fiber optic demodulator then analyzes the information using its own preset algorithm to obtain accurate parameters, promptly report any abnormalities, and effectively reduce economic losses.

[0008] In a preferred embodiment, the present invention can be further configured such that the width of the spiral spacer is greater than the diameter of the wire, and the wire and the spiral spacer are arranged alternately.

[0009] In a preferred embodiment, this utility model can be further configured as follows: multiple ferrules are equally spaced and arranged in a row, and the spiral spacer and ferrules are both made of insulating material.

[0010] In a preferred embodiment, the present invention can be further configured such that: a plurality of glass fiber binding straps are sleeved on the outside of the optical fiber sensor, and the plurality of glass fiber binding straps are respectively fixed to the top of a plurality of ferrules.

[0011] In a preferred embodiment, the present invention can be further configured as follows: multiple glass fiber binding straps are arranged in pairs, with five groups in total, and the two glass fiber binding straps in each group are vertically symmetrical about multiple high-temperature resistant adhesives.

[0012] In a preferred embodiment, the present invention can be further configured such that two connecting rods are fixedly connected to both the top and bottom of the arc plate, and the connecting rods are configured to be arc-shaped.

[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, the fiber optic sensor detects the temperature and shape of the conductor, and the detection information is uploaded to the fiber optic demodulator.

[0027] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0028] It should be understood that these descriptions are merely exemplary and not intended to limit the scope of this invention.

[0029] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, providing a transformer coil for a high-voltage power system.

[0030] Example 1:

[0031] Combination Figure 1-5 As shown, the present invention provides a transformer coil for a high-voltage power system, including a transformer mechanism 100, an isolation mechanism 200 and a detection mechanism 300. The transformer mechanism 100 includes an iron core 110 and a conductor 120 wound around the outside of the iron core 110.

[0032] The isolation mechanism 200 includes a spiral spacer 210 sleeved on the outside of the iron core 110, a plurality of retaining sleeves 220 snapped onto one side of the spiral spacer 210, and an arc plate 230 connecting the plurality of retaining sleeves 220.

[0033] The testing mechanism 300 includes an optical fiber sensor 310 connected between multiple ferrules 220, an optical fiber demodulator 320 disposed on one side of the arc plate 230 and wiredly connected to the optical fiber sensor 310, and a high-temperature resistant adhesive 330 bonded between the ferrules 220 and the optical fiber sensor 310.

[0034] Furthermore, the width of the spiral spacer 210 is greater than the diameter of the wire 120, and the wire 120 and the spiral spacer 210 are staggered. With this size and layout design, the spiral spacer 210 can prevent the wires 120 from stacking and prevent mutual interference between the components.

[0035] Furthermore, the multiple ferrules 220 are arranged in a row with equal spacing. Both the spiral spacer 210 and the ferrules 220 are made of insulating material. The selection of insulating material can effectively prevent current conduction and enhance the safety and stability of the entire transformer coil. The design of the ferrules 220 being arranged in a row with equal spacing allows the arc plate 230 to be more firmly connected between the multiple ferrules 220, ensuring the integrity of the structure. At the same time, the equal spacing arrangement also helps the fiber optic sensor 310 to accurately detect relevant data and reduce detection errors that may be caused by uneven arrangement.

[0036] Example 2:

[0037] Combination Figure 1 , 4 and Figure 5 As shown, based on Embodiment 1, the fiber optic sensor 310 is fitted with multiple fiberglass binding straps 400 on its outer side. The multiple fiberglass binding straps 400 are respectively fixed to the top of multiple sleeves 220. The fiberglass binding straps 400 fix the fiber optic sensor 310 to ensure its positional stability.

[0038] Furthermore, multiple fiberglass binding straps 400 are arranged in pairs, forming five groups. In each group, two fiberglass binding straps 400 are vertically symmetrical about multiple high-temperature resistant adhesives 330. This symmetrical arrangement further enhances the stability of fixing the fiber optic sensor 310, enabling the fiber optic sensor 310 to better resist the influence of factors such as vibration and displacement in complex operating environments.

[0039] Example 3:

[0040] Combination Figure 1 As shown, in the above embodiment, two connecting rods 500 are fixedly connected to the top and bottom of the arc plate 230. The connecting rods 500 are set in an arc shape. The connecting rods 500 are set to facilitate fixing the arc plate 230 inside the external transformer housing where the iron core 110 is placed.

[0041] The working principle and usage process of this utility model are as follows: In the initial state, the iron core 110 and the conductor 120 work together to realize the voltage conversion function, providing a guarantee for the stable operation of the power system. Then, the spiral spacer 210, the sleeve 220 and the arc plate 230 play a good isolation role, preventing mutual interference between the components. When the device is put into operation, the fiber optic sensor 310 detects the temperature and shape of the conductor 120. The detection information is uploaded to the fiber optic demodulator 320. Then, the fiber optic demodulator 320 analyzes the information through its own preset algorithm to obtain accurate parameters and promptly report any abnormalities. The entire design fully considers the characteristics and needs of the high-voltage power system and has excellent performance in terms of transformation, isolation and detection, which can effectively improve the safety and reliability of the power system.

[0042] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
