A new cable dumbbell test piece preparation device

Abstract

The invention discloses a novel cable-dumbbell test piece preparing device. The novel cable-dumbbell test piece preparing device is characterized by comprising an electric pressing plier (1), a dynamic contact (2) and a static contact (3). The dynamic contact (2) comprises an installing base (4) and a dumbbell mold (5); the installing base (4) is inserted into a mold connecting opening (6) in the dynamic contact (2) through a connecting rod (7) of the electric pressing plier (1) and connected with the electric pressing plier (1), the installing base (4) is connected with the dumbbell mold (5), a mold notch (11) is arranged on a trapezoid boss at the end of the dumbbell mold (5), and a semi cylinder provided with a rectangular boss of the static contact (3) is clamped into a clamping groove in the electric pressing plier (1) and connected with the electric pressing plier (1). The novel cable-dumbbell test piece preparing device is easy to operate, safe, reliable, high in mechanical strength and reliability, low in error and wide in application range, the labor intensity and the technical requirements of power cable quality detection are reduced, and the detection efficiency is improved.

Description

Technical field: [0001] The invention relates to a novel cable dumbbell test piece preparation device, which is widely used in the production process of dumbbell test pieces in the inspection of electric power system cable products, and belongs to the technical field of electric power and cables. Background technique: [0002] With the continuous development of economy and society, the speed of power grid construction is accelerating, the demand for power cable products is increasing, and the number of cable manufacturers is also increasing. Due to the different technical levels, production levels, and quality control levels of cable manufacturers, the quality of cable products is uneven. Unqualified cables will directly affect the safe operation of the power system and bring losses to economic and social development. Therefore, for power cables Quality inspection is very important and necessary. [0003] In the power cable industry, the performance of insulation and sheath...
