Abstract

The invention discloses an intelligent SF6 density relay calibration device and method. The device comprises an air source, a calibration operating table, a plurality of SF6 density relays installed on the calibration operating table, a plurality of detection mechanisms arranged in the calibration operating table, and a control mechanism arranged on the calibration operating table, wherein each detection mechanism is connected with the air source and one SF6 density relay. According to the intelligent SF6 density relay calibration device, due to the facts that the calibration operating table is arranged, and the detection mechanisms and the control mechanism are arranged in the calibration operating table, the SF6 density relays which are to be detected and are arranged on the calibration operating table are calibrated. The whole detection process is high in automation degree; after the density relays are installed, automatic detection can be carried out by setting detection parameters through an input device, finally, the detection result can be automatically output through an output device, the manual intervention process is omitted, and the detection precision and the detection efficiency are improved.

Description

technical field [0001] The invention relates to calibration equipment for electrical equipment, in particular to an intelligent SF 6 Density relay verification device and method. Background technique [0002] SF 6 As an insulating medium with good insulating properties and arc extinguishing properties, gas is widely used in high-voltage switchgear gas insulation. while SF 6 Gas density is the effect of SF 6 The main factor of gas insulation performance, so for SF 6 device terms, SF 6 Whether the density relay works normally is an important content to ensure the normal and safe operation of the equipment. [0003] At present, when the density relay is calibrated in the calibration laboratory, the density relay calibration procedure requires that the density relay should be kept upright or in a normal working state during the calibration process. Since there is no density relay calibrator used in the laboratory, in The calibration of the density relay in the laboratory ...
