A low-voltage metering box mechanical static load performance testing platform

Abstract

The invention provides a mechanical static load performance testing platform of a low pressure metering box, the mechanical static load performance testing platform comprises a main fixing platform, static force application equipment and a spiral pulley structure; the main fixing platform comprises a rectangular flat plate parallel to the ground, baffle plates arranged on the flat plate, brackets, push rods and sliding shafts; both sides of the low pressure metering box are respectively provided with the baffle plates; the sliding shafts are arranged on the outer sides of the baffle plates; the brackets are provided with sliding shafts perpendicular to the ground, one end of the push rod is connected with a sliding shaft on the bracket, the other end of the push rod is close to the low pressure metering box; the static force application equipment comprises a tensile machine; the spiral pulley structure comprises a spiral guide rod device and a pulley, one end of the tensile machine is connected with the spiral guide rod device by a soft rope of the pulley, and movements of the spiral guide rod device controls the tensile machine to apply forces of different positions and directions on the low pressure metering box. The mechanical static load performance testing platform can complete stiffness tests, static load force tests, torsion tests, metal insert tests, door and mounting plate performance tests and the like of the low pressure metering box.

Description

technical field [0001] The invention relates to the detection field of low-voltage metering boxes, in particular to a mechanical static load performance testing platform for low-voltage metering boxes. Background technique [0002] The operating environment of the low-voltage metering box is complex, and it is generally exposed outdoors. It is greatly affected by weather changes, which affects its stable and safe operation. The low-voltage metering box is different from ordinary low-voltage complete sets of equipment. It is not only the first line of defense to ensure the new generation of smart meters against electricity theft, but also the first to ensure the safety of users' lives and property in the event of short-circuit faults, flame spread and other accidents. line of defense. The low-voltage metering box works in a high-temperature environment for a long time, and it is easy to cause the failure of the contactor and leakage protector due to aging. Direct and indire...
