Description

Technical Field

[0001] The invention belongs to the technical field of current transformer housings, and in particular relates to a current transformer housing protection mechanism for load shedding. Background Art

[0002] A current transformer is a device that converts high voltage current or high current into low voltage current or small current for measurement, metering and protection applications. According to the principle of electromagnetic induction, when current flows through the primary winding (primary), a magnetic flux will be generated in the iron core. This magnetic flux will pass through the secondary winding (secondary), thereby generating an induced electromotive force and current in the secondary winding. The magnitude of the induced electromotive force is proportional to the primary current and inversely proportional to the number of turns of the secondary winding.

[0003] Its internal structure is usually made of high magnetic permeability materials to improve the transmission efficiency of magnetic flux. The common iron core is composed of silicon steel sheets, and the external windings include primary windings and secondary windings, which are wound on the iron core. The primary winding has a small number of turns and is connected in series in the circuit of the current to be measured; the secondary winding has a large number of turns and is connected in series in the measuring instrument and protection circuit.

[0004] After searching the prior art for "a current transformer housing", the announcement number is "CN219936839U". This device is convenient for converting and adjusting the P1 and P2 surfaces of the current transformer housing, which is convenient for line redirection or other work. It does not waste too much time on the conversion of the P1 and P2 surfaces. The operation is relatively simple and convenient. However, when the transformer is used for measurement, the coil needs to be wound on the surface of the transformer first. However, the existing device lacks a guiding structure during winding, which causes the coil to be affected by its own material. It is difficult to keep the coil tightly wound during winding, and the coil will become loose after winding, causing uneven winding of the coil to affect the accuracy of the measured value.

DETAILED DESCRIPTION

[0043] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0044] See also Figure 1-Figure 8 , the present invention provides a technical solution:

[0045] A load shedding current transformer housing protection mechanism, comprising: a mounting seat 100, both ends of the mounting seat 100 are provided with mounting grooves 200, and the ends of the mounting seat 100 are arranged in an upwardly curved shape; a housing mechanism 300, the housing mechanism 300 is installed at the upper end of the mounting seat 100, and the housing mechanism 300 is located between the two mounting grooves 200; wherein the housing mechanism 300 comprises a coil winding assembly 310 arranged at the upper end of the mounting seat 100, an internal protection assembly 320 is arranged inside the coil winding assembly 310, a connection end protection assembly 330 is installed on the surface of the coil winding assembly 310 away from the mounting seat 100, and the surface of the connection end protection assembly 330 extends to the inside of the internal protection assembly 320;

[0046] like Figure 1-Figure 7 As shown, the coil winding assembly 310 includes an outer shell 311, a corner protection frame 312, an internal threaded tube 313, an inner ring 316, and a side groove 3110. The two outer shells 311 are arranged at the upper end of the mounting seat 100. One side of the outer shell 311 is fixedly connected to the upper end of the mounting seat 100. The corner protection frame 312 is sleeved at the sharp corner of the outer shell 311. The internal threaded tube 313 is fixedly connected to the inner wall of the outer shell 311 on one side. The inner ring 316 is fixedly connected to the inner wall of the outer shell 311. A side groove 3110 is opened on the side of the outer shell 311 on one side. The two outer shells 311 are clamped with each other. The surfaces of adjacent corner protection frames 312 are fixedly connected to each other. The ends of the internal threaded tube 313 respectively penetrate to the outside of the adjacent outer shells 311. The inner wall of the inner ring 316 is provided with two groups of inclined grooves 319, and the inclined directions of the two groups of inclined grooves 319 are opposite. The surface of the outer shell 311 is provided with horizontal insertion grooves 315, and the ends of the inclined grooves 319 are connected with adjacent horizontal insertion grooves 315. The other end of the internal threaded tube 313 is fixedly connected with a blocking cone block 318, and the surface of the other side outer shell 311 is provided with a conical hole 317, and the cross section of the conical hole 317 is conical, and the blocking cone block 318 matches the conical hole 317. The inner wall of the internal threaded tube 313 is threadedly connected with a side connecting bolt 314, and the corner protection frame 312 is sleeved on the surface of the adjacent side connecting bolt 314;

[0047] When the device is in use, the winding coil can be wound along the surface of the outer shell 311, so that the coil enters the inside of the horizontal insertion groove 315, which assists in forming a uniform distribution effect of the winding. When winding, the horizontal insertion groove 315 is provided, and the guiding and positioning of the inclined groove 319 are cooperated to make the winding enter the adjacent horizontal insertion groove 315 for continuous winding. At the same time, after the winding is completed, the side connection bolt 314 can be turned into the internal threaded tube 313 to assist in forming a tight connection between the two outer shells 311. When the side connection bolt 314 is screwed into the inside of the internal threaded tube 313, it drives the corner protection frame 312 to fit the surface of the outer shell 311, and then the corner protection frame 312 can be provided to assist in positioning the coil located inside the horizontal insertion groove 315, so as to keep the winding coil from being scattered, ensure the uniform and stable winding of the coil, and make the measurement result more accurate. In addition, the corner protection frame 312 can also protect the outer shell 311.

[0048] like Figure 1 , Figure 4 , Figure 5 and Figure 7 As shown, the internal protection component 320 includes an annular airbag 321, a first airbag 322, a rubber plate 326, and a positioning frame 327. The annular airbag 321 is sleeved on the surface of the inner ring 316. An inner cavity 325 is provided inside the outer shell 311. The rubber plate 326 is fixedly connected to the inner wall of the inner cavity 325. The positioning frame 327 is fixedly connected to the end of the rubber plate 326. The first airbag 322 is provided between the positioning frames 327 on one side. The positioning frame 327 is fixedly connected to the inner wall of the inner cavity 325. The first airbag 322 is fixedly connected to the inner wall of the inner cavity 325. The first airbag 322 is communicated with the outer shell 311. A resistance groove 323 is provided on the surface of the first airbag 322. A resistance plate 324 is fixedly connected to the inner wall of the resistance groove 323.

[0049] When the two inner rings 316 are fitted together, the annular airbag 321 can block the gap between the two inner rings 316. When the silicon steel sheet core is placed inside the outer shell 311, the annular airbag 321 is in a contracted state because the first airbag 322 is not squeezed. After the core is placed, the rubber plate 326 keeps the core in the position where it is pushed out. At this time, the core contacts the surface of the positioning frame 327. At the same time, the core contacts the contact plate 324 and squeezes the contact groove 323 on the surface of the first airbag 322, causing the first airbag 322 to contract and inject the internal gas into the annular airbag 321. At this time, the annular airbag 321 is located between the core and the inner ring 316, assists in positioning the core during the expansion process, and can block the gap between the two inner rings 316, thereby reducing the corrosion of the silicon steel sheet caused by moisture entering the shell, and ensuring more accurate measurement results.

[0050] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, the connection end protection assembly 330 includes a connection placement frame 331, a protection cover 332, a second airbag 334, and an edge pressure plate 335. The connection placement frame 331 is fixedly connected to the upper end of the external shell 311, the protection cover 332 is clamped on the upper end of the connection placement frame 331, the second airbag 334 is fixedly connected to the inner top wall of the protection cover 332, and the edge pressure plate 335 is fixedly connected to the lower end of the surface of the protection cover 332. The upper end of the connection placement frame 331 is provided with a connection placement groove 333, and the lower end of the second airbag 334 penetrates into the inside of the connection placement groove 333. The lower end of the edge pressure plate 335 is provided with a sealing airbag ring 336, which is sleeved on the surface of the connection placement frame 331, the lower end of the sealing airbag ring 336 contacts the upper end of the external shell 311, and the lower end of the sealing airbag ring 336 penetrates into the inside of the side groove 3110. An extrusion airbag 337 is fixedly connected to the inner wall of the side groove 3110, and the sealing airbag ring 336 is in communication with the extrusion airbag 337. An extrusion plate 338 is fixedly connected to one side of the extrusion airbag 337, and the extrusion plate 338 is slidably connected to the inner wall of the side groove 3110;

[0051] When the device is connected and used, the end of the connecting line can pass through the round hole opened on the side of the protective cover 332 and the line end can be inserted into the connection placement groove 333 to connect with the iron core coil. At this time, the protective cover 332 moves down to drive the second airbag 334 to enter the connection placement groove 333 to assist in sealing the end of the connecting line, reduce the contact between external moisture and the connection end, maintain good connection of the end, so that the contact is good and the measurement value is stable during the detection process, and when the corner protection frame 312 is installed in place, it drives the extrusion plate 338 to slide inside the side groove 3110, thereby compressing the extrusion airbag 337 to shrink. At this time, the extrusion airbag 337 will inject gas into the sealing airbag ring 336, so that the gap between the lower end of the protective cover 332 and the upper end of the connection placement frame 331 is blocked by the sealing airbag ring 336, so that the contact of the detection line end is good, and the measurement result is guaranteed to be more accurate.

[0052] Working principle: When the device is in use, the winding coil is wound along the surface of the outer shell 311, and the coil enters the horizontal insertion groove 315. The horizontal insertion groove 315 cooperates with the inclined groove 319 to form a guide and positioning during winding. After the winding is completed, the side connecting bolt 314 is screwed into the internal threaded tube 313 to assist the two outer shells 311 to fit tightly. The side connecting bolt 314 is screwed into the internal threaded tube 313 to drive the corner protection frame 312 to fit the surface of the outer shell 311, and the corner protection frame 312 is screwed into the internal threaded tube 313. The frame 312 assists in positioning the coil inside the horizontally inserted slot 315, and the corner protection frame 312 protects the outer shell 311. When the two inner rings 316 are attached, the annular airbag 321 blocks the gap between the two inner rings 316. The iron core is placed in place and the rubber plate 326 is used to hold the iron core in place. The iron core contacts the contact plate 324 to squeeze the first airbag 322 to contract, and gas is injected into the annular airbag 321. The annular airbag 321 expands to position the iron core and blocks the gap between the two inner rings 316.

[0053] The end of the connecting wire passes through the circular hole opened on the side of the protective cover 332 and is inserted into the connecting placement groove 333 to be connected to the iron core coil. The protective cover 332 moves downward to drive the second airbag 334 to enter the connecting placement groove 333 to assist in sealing the end of the connecting wire. When the corner protection frame 312 is installed, it drives the extrusion plate 338 to slide in the side groove 3110, and then compresses the extrusion airbag 337 to inject gas into the sealing airbag ring 336. The gap between the protective cover 332 and the connecting placement frame 331 is blocked by the sealing airbag ring 336, so that the detection line end is in good contact, which ensures that the measurement result is more accurate.
