Description

technical field [0001] The invention belongs to the technical field of high-voltage testing in the electric power industry, and in particular relates to a lifting base for electrical insulation performance testing of a composite silicone rubber metal oxide arrester. Background technique [0002] Surge arrester is one of the important protection devices to ensure the safe operation of the power system, mainly used to limit the lightning overvoltage transmitted from the line or the internal overvoltage caused by operation. In order to ensure its safe operation, according to the relevant provisions of GB50150-2006 "Electrical Equipment Handover Test Standard for Electrical Installation Engineering" and DL / T596-1996 "Preventive Test Regulations for Electric Equipment", electrical tests must be carried out on it regularly. With the expansion of power production scale and the improvement of technical level, the types, parameters and technical performance of power equipment have de...

Problems solved by technology

However, due to the hooks, slings, lead wires, frames and other objects used in this method are likely to cause external interference, ground potential rise, etc., directly affect the accuracy of the data, and cannot truly reflect the insulation quality of the composite silicon rubber metal oxide arrester. The cumbersome links such as hoisting and unloading are easy to cause damage to the arrester, and also waste huge manpower and material resources
