Description

Online monitoring device is put in sleeve pipe office

Technical Field

The utility model relates to a monitoring devices is put in the office, especially relates to an online monitoring devices is put in sleeve pipe office.

Background

The partial discharge refers to discharge that occurs between electrodes but does not penetrate the electrodes, and is a phenomenon in which repeated breakdown and extinction occur under the action of high electric field strength due to weak current existing inside the insulation of equipment or defects caused during production. It is expressed as the breakdown of gas in the insulation, the local breakdown of solid or liquid medium in a small range, or the local breakdown discharge caused by the concentration of the field intensity at the edge and sharp corner of the metal surface. The energy of this discharge is very small, so its short-term presence does not affect the dielectric strength of the electrical equipment. However, if partial discharges occur continuously in the insulation of the electrical equipment under the operating voltage, the weak discharges will generate cumulative effects, which will gradually deteriorate the dielectric properties of the insulation and enlarge local defects, and finally lead to the breakdown of the whole insulation. Detect through ultrasonic sensor among the prior art, the signal transmission of sensor carries out processing, demonstration and the warning of signal to the partial discharge on-line monitoring device in, and current partial discharge on-line monitoring device is fixed on electrical equipment, inconvenient dismantlement, adopts the mode of hanging, and is fixed insecure, and the easy water intaking of kneck that the partial discharge on-line monitoring device was put simultaneously leads to not being suitable for the outdoor condition, and application scope is narrow.
