[0002] PY core is a specific type of current transformer core, mainly used for protection with transient characteristics. It is also a ring-shaped core with an air gap, used in fast relay protection wiring of ultra-high voltage lines and large generators and transformers. In order to ensure the stability of the core during transportation and use, epoxy resin will be encapsulated on the outside of the core.

[0003] After searching, the patent number CN220138081 U discloses a TPY-level transient current transformer core. The core is provided with studs and nuts between the first core and the second core. The two ends of the first core and the second core can be fixedly connected by the cooperation of the studs and nuts, and the studs and nuts are both located inside the mounting groove to avoid the exposure of the studs and nuts, thereby reducing the installation volume of the first core and the second core.

[0004] However, when the two sides of the iron core are spliced, the connection can be completed through the cooperation of multiple nuts and bolts, resulting in low positioning and connection efficiency between the two semicircular iron cores and complicated operation. Utility Model Content

[0006] Therefore, the purpose of the utility model is to provide a TPY core based on a three-dimensional rolled epoxy resin reinforcement process, which solves the problem that the half semicircular core is connected by bolts and nuts, which is cumbersome to operate and has low connection efficiency.

[0011] Preferably, two adjacent clamping plates are staggered front to back.

[0012] Preferably, two symmetrically arranged positioning rods are fixed on both sides of the insulating plate, and two symmetrically arranged positioning grooves are provided at one end close to the first iron core and the second iron core. The positioning rods are plugged into the positioning grooves, and the plugging of the positioning rods and the positioning grooves enables the insulating plate to be accurately plugged into and matched with the first iron core or the second iron core, thereby improving the connection stability of the first iron core and the second iron core.

[0013] Furthermore, the insulating plate is arranged in a ring shape, so that the two clamping plates can be stably plugged into and matched with the grooves inside the first iron core and the second iron core.

[0014] Preferably, a slope is provided on one side of the two clamping plates close to the clamping rod, so that when the clamping plates are in contact with the clamping rod, the clamping plates can be pushed and move along the support rod.

[0015] Preferably, the two clamping plates are provided with through holes inside to match the support rods, so that the clamping plates can slide stably on the rod walls of the support rods.

[0016] Preferably, both of the two springs are compression springs, which can enable the springs to rebound quickly after being compressed, thereby facilitating resetting the position of the card after it is moved.

[0027] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0028] The utility model embodiment discloses a TPY core based on a three-dimensional rolled epoxy resin reinforcement process.

[0029] Example 1

[0030] The utility model provides Figure 1-4 A TPY core based on a three-dimensional rolled epoxy resin reinforcement process shown in the figure comprises an epoxy resin encapsulation layer 1 and a first core 2 and a second core 3 arranged inside the epoxy resin encapsulation layer 1, two symmetrically arranged insulating plates 4 are arranged near one end of the first core 2 and the second core 3, the insulating plates 4 are arranged in a ring shape, two symmetrically arranged clamping plates 5 are arranged inside the insulating plates 4, and two adjacent clamping plates 5 are arranged front and back staggered, a groove 6 is opened near one end of the first core 2 and the second core 3, a clamping rod 7 is fixedly provided on the inner wall of the groove 6, a clamping hole 8 is opened inside the clamping plate 5, and the clamping rod 7 is inserted into the two clamping holes 8;

[0031] A support rod 9 is fixedly provided on the inner wall of the insulating plate 4, and an elastic connection mechanism is provided between the clamping plate 5 and the support rod 9. The elastic connection mechanism includes a spring 10. The spring 10 is sleeved on the outer side of the support rod 9. The clamping plate 5 is rotatably sleeved on the outer side of the support rod 9. The two ends of the spring 10 are fixedly connected to the support rod 9 and the clamping plate 5 respectively, and the two springs 10 are both compression springs.

[0032] When preparing the iron core, the first iron core 1 and the second iron core 2 after the iron core is cut as a whole are combined, and two insulating plates 4 are set between the first iron core 1 and the second iron core 2. First, the two insulating plates 4 are connected to the two ends of the first iron core 1 so that the internal card hole 8 of the upper card plate 5 can be plugged into the card rod 7 inside the groove 6, and the position of the insulating plate 4 is determined. Then the second iron core 3 is brought into contact with the insulating plate 4 so that the lower card plate 5 is plugged into the card hole 8. During the contact between the card plate 5 and the card rod 7, the card plate 5 is pushed by the card rod 7 and slides along the support rod 9, and the spring 10 is stretched. When the card hole 8 and the card rod 7 are on the same horizontal line, the card plate 5 rebounds under the elastic force recovery of the spring 10 so that the card rod 7 is inserted into the card hole 8. The position of the card plate 5 is determined, and the first iron core 2 and the second iron core 3 can be connected, ensuring the stability of the iron core and the epoxy resin encapsulation layer 1 during the connection process.

[0033] Example 2

[0034] Embodiment 2 is based on Embodiment 1 and enables the first core 2, the second core 3 and the insulating plate 4 to be stably connected. Figure 2-3 As shown, two symmetrically arranged positioning rods 11 are fixedly provided on both sides of the insulating plate 4, and two symmetrically arranged positioning grooves 12 are provided at the ends close to the first iron core 2 and the second iron core 3, and the positioning rods 11 are plugged into and matched with the positioning grooves 12.

[0035] When the first core 2 or the second core 3 is connected to the insulating plate 4, the connection position of the insulating plate 4 can be determined by plugging the positioning rods 11 on both sides of the insulating plate 4 and the positioning grooves 12 at the ends of the first core 2 and the second core 3, so that the clamping plate 5 can be stably plugged and matched with the clamping rod 7, thereby improving the connection accuracy of the first core 2 and the second core 3.

[0036] Example 3

[0037] Embodiment 3 is based on Embodiments 1-2 in order to enable the card plate 5 and the card rod 7 to be stably plugged together. Figure 4 As shown, the two clamping plates 5 are provided with through holes 14 for the support rod 9 to pass through, and the two clamping plates 5 are provided with inclined surfaces 13 on one side close to the clamping rod 7 .

[0038] Since one side of the clamping plate 5 is arranged in an inclined surface, when the clamping plate 5 extends into the groove 6 and cooperates with the clamping rod 7, as the clamping plate 5 goes deeper, under the contact between the inclined surface 13 and the clamping rod 7, since the position of the clamping rod 7 is fixed, the inclined surface 13 is pushed and drives the clamping plate 5 to move along the support rod 9, so that the subsequent clamping rod 7 is stably inserted into the clamping hole 8 to complete the connection between the first iron core 2, the second iron core 3 and the insulating plate 4.

[0039] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
