Embodiment 1

[0031] The detector to be calibrated in this embodiment is as figure 1 and figure 2 As shown, the specific calibration method is as follows:

[0032] S1: Take absolute ethanol and pure water according to the volume ratio of 1:1000, put them into a jar and mix them evenly to obtain a test solution.

[0033] S2: Take 100mL of the test solution and put it into a 1000mL transparent glass volumetric flask, then seal the volumetric flask with a sealing film to obtain a gas generating liquid; repeat the above steps to make three bottles of gas generating liquid, numbered A bottle, B bottle, and C bottle respectively bottle.

[0034] S3: Put A bottle, B bottle, and C bottle of gas-generating liquid into an incubator at 25-30°C for 24-30 hours. The volatilized gas in the sealed volumetric flask reaches the maximum level, and the test gas of A bottle and B bottle are obtained. Bottle Test Gas and C Bottle Test Gas.

[0035] S4: When the detector is turned off, press the power butto...

Abstract

The invention provides a calibration method for a PVC cable gas detector. The volatile gas is prepared by mixing and sealing anhydrous ethanol and pure water, and then the gas detector is used for testing. The time of multiple tests is close to the value of the gas concentration. Calibration of cable gas monitors. The calibration method of the PVC cable gas detector provided by the invention has simple steps, is convenient to operate, and can quickly calibrate the gas detector.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment detection, and in particular relates to a calibration method for a PVC cable gas detector. Background technique [0002] PVC cable material is cheap and has excellent performance. It has long occupied an important position in the insulation and protection materials of wire and cable. However, with the increase of operating time, partial discharge will occur inside the cable, which will easily lead to the decline of insulation performance and cause major safety hazards. Finding a practical way to detect the insulation condition of cables in operation has become an urgent research problem. [0003] The inventor of the present invention has independently developed a hand-held cable gas detector (hereinafter referred to as the detector), which adopts the most advanced large-scale integrated circuit technology. The detector adopts a self-priming air pump to collect gas, and the sensitive e...
