Abstract

The invention discloses an aluminum polar plate welding method used for integral calibration of a power frequency electric field measuring instrument. The aluminum polar plate welding method comprisesthe following step: welding a plurality of aluminum plates into an electrode polar plate with an equivalent diameter greater than or equal to 4 m, wherein welding adopts a way of interval type welding on the back surface and no welding on the front surface. The way of interval type welding on the back surface and no welding on the front surface is adopted, so that the problem that flatness does not meet requirements due to a full-welding way of the aluminum polar plate.

Description

technical field [0001] The invention relates to the technical field of power equipment calibration, in particular to an aluminum plate welding method used for the overall calibration of a power frequency electric field measuring instrument. Background technique [0002] The power frequency electric field is an important evaluation index in the environmental impact assessment of power transmission and transformation projects and the environmental protection acceptance of completion. The devices used for power frequency electric field measurement are called "power frequency electric field measuring instrument", "power frequency Frequency electric field measuring device" and so on, according to the provisions of my country's Metrology Law, these equipment should be verified or calibrated to be qualified when used. [0003] my country's legal metrology institutions are responsible for the traceability of the value of such equipment, but at present, when the legal metrology instit...
