Problems solved by technology

But even considering the maximum temperature difference in different regions, the maximum deformation caused by temperature changes will be within a certain value, generally plus or minus ten centimeters, for gas insulated equipment, the deformation of plus or minus ten centimeters is relatively large, if it cannot be compensated , will greatly affect the sealing performance of the insulating and sealing equipment

Abstract

The invention discloses a telescopic joint deformation detection device and a measurement method, the deformation detection device comprises a plurality of mounting hoops, a U-shaped hoop, a variablelength unit, an on-site scale, a displacement sensor and a circuit board waterproof box, the mounting hoops are connected with telescopic joints, and each telescopic joint comprises a corrugated pipeand fixed supports arranged at two ends of the corrugated pipe; the mounting hoops are arranged at one ends of the fixed supports and are compatible with the fixed supports with different thicknessesafter being connected through a fastener in a penetrating manner, and meanwhile, punching of the fixed supports is reduced; the variable length unit comprises a variable-length rod, a fisheye joint and a U-shaped connector, the fisheye joint is used for adapting to multi-angle deformation and movement of the telescopic joint, the measurement precision is improved, and the service life is prolonged; and the on-site scale is used for directly measuring the length value of the telescopic joint through left-right sliding when the telescopic joint deforms. The measurement method is simple, the measurement result is visual, and the measurement precision is accurate.

Description

technical field [0001] The invention relates to the technical field of deformation detection of expansion joints, in particular to a detection device and a measurement method for deformation of expansion joints. Background technique [0002] In the power system, the gas-insulated combined electrical equipment GIS and the gas-insulated metal-enclosed transmission line GIL are often equipped with expansion joints. The length of the expansion joints in different GIS and GIL varies from 20 to 30 cm to 100 cm. It is used to compensate the deformation caused by thermal expansion and contraction due to temperature changes, so as to ensure the safe operation of equipment and pipelines. But even considering the maximum temperature difference in different regions, the maximum deformation caused by temperature changes will be within a certain value, generally plus or minus ten centimeters, for gas insulated equipment, the deformation of plus or minus ten centimeters is relatively large...
