Description

Technical Field

[0001] The utility model relates to the field of porcelain insulators, in particular to an aging-resistant high-voltage porcelain insulator. Background Art

[0002] Porcelain insulators, also known as electric porcelain insulators, are insulators made of electrical ceramics. They play a key role in the power system and are mainly used in power transmission and distribution systems, such as high-voltage cables, overhead lines, substations, circuit breakers and other equipment. They can effectively prevent current leakage and ensure the efficiency and stability of power system operation.

[0003] When using columnar porcelain insulators, cement adhesive is generally used to connect the insulating parts and metal parts. However, during gluing, only cement adhesive is used to connect the insulating parts and metal parts. After the insulator is used for a long time, the cement adhesive will age, resulting in a reduction in the service life of the porcelain insulator caused by the aging of the glue assembly.

[0004] Therefore, it is necessary to propose an aging-resistant high-voltage porcelain insulator to solve the above problems. Utility Model Content

[0014] Technical effects and advantages of the utility model:

[0015] 1. The vertical plate is used to squeeze the inner wall of the gluing hole. When the porcelain parts and metal parts are connected by cement adhesive, the connection strength of the porcelain parts and metal parts is reinforced for the second time to prevent the aging of the cement adhesive from affecting the service life of the porcelain insulator. The position of the support block can also control the use of cement adhesive. When gluing the porcelain parts and metal parts, the glue injection hole will be opened only after the porcelain parts are fixed to complete the gluing, which can prevent gluing errors;

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1 - Figure 5 An aging-resistant high-voltage electric porcelain insulator shown in the figure comprises a porcelain part 1 and a metal part 2 for carrying the porcelain part 1. A wire carrying groove 101 for carrying a cable is provided at the upper end of the porcelain part 1. A connecting rod 3 is fixedly provided at the upper end of the metal part 2. A glue hole 4 is provided at one end of the porcelain part 1 corresponding to the metal part 2. The glue hole 4 is elliptical in shape. The cross section of the connecting rod 3 is circular in shape. The connecting rod 3 is movably located inside the glue hole 4.

[0025] Two support blocks 10 are movably provided at the upper end of the connecting rod 3, and vertical plates 12 are fixedly provided at the ends of the support blocks 10. The vertical plates 12 abut against the inner walls of the glue holes 4. Glue injection holes 5 are provided on the inner sides of the metal part 2 and the connecting rod 3. A sliding groove 7 for disconnecting the glue injection holes 5 is provided at the upper end of the connecting rod 3. A connecting hole 11 is penetrated at one end of the support block 10, and the connecting hole 11 is used to connect the disconnected glue injection holes 5.

[0026] The inner wall of the gluing hole 4 is squeezed by the vertical plate 12, and when the porcelain part 1 and the metal part 2 are connected by cement adhesive, the connection strength between the porcelain part 1 and the metal part 2 is reinforced for a second time, so as to prevent the cement adhesive from aging and affecting the service life of the porcelain insulator. In addition, the use of the cement adhesive can be controlled by the position of the support block 10. When gluing the porcelain part 1 and the metal part 2, the glue injection hole 5 will be opened only after the porcelain part 1 is fixed to complete the gluing, so as to prevent gluing errors.

[0027] Two slide plates 8 are slidably disposed inside the slide groove 7 , and springs 9 are fixedly disposed on corresponding sides of the two slide plates 8 , and one side of the slide plates 8 is fixedly connected to the end of a support block 10 .

[0028] A retaining ring 6 is movably provided on the inner side of the gluing hole 4. The retaining ring 6 is elliptical in shape. In order to fit the shape of the gluing hole 4, a circular hole for the connecting rod 3 to pass through is opened on one side of the retaining ring 6. The retaining ring 6 and the connecting rod 3 are in interference fit to ensure that the retaining ring 6 can stay on the outer side of the connecting rod 3 without being subjected to external force. A plurality of air outlet holes 13 are opened on one side of the retaining ring 6 to prevent a large number of bubbles in the gluing hole 4.

[0029] By setting the retaining ring 6, when the cement adhesive is injected into the gluing hole 4, it is possible to prevent a large number of bubbles from being retained in the gluing hole 4, which would cause a large number of bubbles to affect the gluing quality, and the retaining ring 6 will move toward the metal part 2 following the injection of the cement adhesive to increase the pressure of the cement adhesive inside the gluing hole 4, thereby increasing the connection strength of the cement adhesive.

[0030] The outer side of the vertical plate 12 fits the corresponding inner side of the glue hole 4. The glue hole 4 is elliptical. The ellipse generally has two vertices, and the outer side of the vertical plate 12 completely fits the inner arc surface of one of the vertices.

[0031] Working principle: The operator places the connecting rod 3 on the metal part 2 inside the glue hole 4 of the porcelain part 1 and then rotates the metal part 2, so that the connecting rod 3 rotates, and the connecting rod 3 drives the support block 10 to rotate, so that the support block 10 drives the vertical plate 12 to rotate, and the end of the vertical plate 12 contacts the inside of the glue hole 4, and then the vertical plate 12 contacts the corresponding vertex in the glue hole 4, and the slide plate 8 is squeezed by the spring 9, and the support block 10 can only slide left and right through the limit of the slide plate 8;

[0032] The support block 10 drives the connecting hole 11 to connect the glue injection hole 5, and glue is injected into the glue hole 4 through the glue injection hole 5. When gluing, the cement adhesive enters the glue hole 4, and the cement adhesive squeezes the retaining ring 6, so that the pressure in the retaining ring 6 and the glue hole 4 becomes larger, and the air is discharged from the air outlet 13 to improve the gluing quality.
