Description

technical field [0001] The invention belongs to the technical field of lightning arresters for electric power systems, and in particular relates to a clamping device for a resistance plate grinding machine. Background technique [0002] Zinc oxide resistors are the core components of surge arresters for power grid operation protection equipment. At present, the potential gradient of existing zinc oxide resistors is low, generally ranging from 190 to 220V / mm. As the voltage of the protective equipment increases, the number of superimposed zinc oxide resistors used in the arrester will increase accordingly, and the volume and weight will increase accordingly, and the height cannot be reduced, which cannot meet the requirements of equipment miniaturization, especially with the development of power system GIS Widely used, it is imminent to require the miniaturization of the matching tank arrester. [0003] The existing resistors are divided into large resistors and small resist...

AI Technical Summary

Problems solved by technology

Miniaturized tank arresters require small resistors, and the small resistors are polished flat. At present, it is known that the production process of small resistors is completed by people, clamps, and grinding machines. During the production process, when the staff used clamps to clamp the resistance piece and sent it into the grinding machine, the contact between the resistance piece and the grinding disc of the grinding machine was inconsistent due to the force and speed generated by friction, and the patterns on the two polishing surfaces of the resistance piece were messy. When two resistors are stacked and used, the gap between the polished surfaces of the two chips is slightly larger, which affects the appearance of the resistor, and the product qualification rate is unstable, which affects product quality. In addition, the existing manual operation of the resistor has low production efficiency. high production cost
