Embodiment Construction
[0020] Below in conjunction with accompanying drawing, the present invention is described in further detail:
[0021] See attached figure 1 , with figure 2 , an insulating pull rod, structurally comprising an insulating resin cured product 1, a metal insert 2, two holes 3 perpendicular to the axial direction of the metal insert 2 are radially opened on the metal insert 2, and the gap between the two holes 3 The angle between them is 90 degrees, and the two holes 3 are in the same section; the two holes 3 can also be distributed in different sections, and the minimum aperture of the aperture is ≥ 3 mm, and the maximum aperture does not affect the strength of the insert itself. limit.
[0022] Preferably, the metal insert, for example, has three holes in the radial direction at a certain angle with the axial direction of the metal insert, the angles between the three holes are 120 degrees to each other, and the minimum hole diameter is ≥ 3mm, and the maximum hole diameter is ...

The invention discloses a method for increasing the tensile strength of a resin-insulated product. The resin-condensate embedded end of a metal inserting piece of an insulated product, such as the traditional insulator, an insulated pull rod, and the like is radially provided with a hole. The invention is characterized in that the hole is arranged on the metal inserting piece according to following requirements: the single hole or multiple holes must be arranged at the embedded end of the metal inserting piece, the direction of the single hole or the multiple holes must has an included angle theta with an axial direction of the metal inserting piece, and the included angle can be large enough to be an axial section plane; when the number of the holes is multiple, the holes are arranged inthe same section or in the different sections of the vertical metal inserting piece; when the number of the holes is two, the included angle of the two holes is preferentially 90 degrees; when the number of the holes is more than two, the included angles are preferentially same, the side of the hole, which is near to an inner end, or one side of the joint of the two holes, which is near to the inner end, is correspondingly provided with an angle R which can be large enough; the aperture of the hole is related to the tensile strength in a certain range, the minimum aperture is greater than or equal to 3mm, and the maximal aperture is limited so as not to influence the self strength of the inserting piece. The invention can effectively increase the tensile strength of the resin-insulated product.
Description
technical field [0001] The present invention relates to a method for increasing tensile strength, more particularly, the present invention is a method for increasing tensile strength of resin insulation products. Background technique [0002] Insulation products such as insulators and pull rods are often used in power transmission and transformation equipment, and these products are required to have good insulation performance and high mechanical strength; however, most of the existing insulator products have problems such as low mechanical strength and easy breakage , the axial tensile force that can withstand is small, and its strength will cause problems such as breakage when it is used for a long time or when the tensile force is large, causing damage to electrical equipment and circuit system failures. For example, in insulating pull rod products, if the insulation The tensile strength of the tie rod is not high enough, and the repeated action makes the reliability of t...
