A water level detection method, device, equipment, storage medium and system, which are applied to a respiratory humidification apparatus, the respiratory humidification apparatus including a humidification chamber that includes a float, where the method includes: obtaining a float position image captured by a current camera; performing a grayscale processing on the float position image to obtain a current grayscale image data; generating a grayscale reference line and a grayscale image curve based on the current grayscale image data, where the grayscale image curve is a relationship curve between the current grayscale image data and a height value of the humidification chamber; determining a height value of the float according to a relative position relationship between the grayscale reference line and the grayscale image curve.

Water level detection method, device, equipment, storage medium and system

A device and method for degassing an on-load tap-changer (OLTC) of a transformer for convenient on-site operation. The degassing device includes an OLTC. The OLTC is respectively connected with an oil suction pipe and an oil injection pipe. One end of the oil suction pipe extends to the inside bottom of the OLTC, and the other end of the oil suction pipe extends to the outside of the OLTC to connect with an oil suction and degassing device. One end of the oil injection pipe extends to an upper part inside the OLTC, and the other end of the oil injection pipe extends to the outside of the OLTC to connect with a vacuum oil injection device. The present disclosure has the advantages of convenient on-site operation, excellent degassing effect, simple structure and convenient installation, reduces degassing time and manpower and investment in maintenance, and improves degassing quality.
