Bushing end screen signal adapter used for sewage treatment

Abstract

The invention relates to a bushing end screen signal adapter used for sewage treatment, and aims at providing a transformer bushing end screen signal adapter which is easy and convenient to operate and accurate in detection signal. The bushing end screen signal adapter comprises an electrode interface member, an angle connector and a capacitor base. The electrode interface member is internally provided with an electrode sheath. The rear end of the electrode interface member is connected with the front end of the angle connector. The electrode sheath is internally provided with a cylindrical copper electrode. The rear end of the copper electrode stretches into a second cavity arranged in the angle connector. The bottom end of the angle connector is connected with the top end of the capacitor base. The capacitor base is internally provided with a first capacitor, a second capacitor, a discharge tube and a transient diode. The first capacitor, the second capacitor, the discharge tube and the transient diode are connected in parallel between a signal sampling end and a signal lead-out end. The signal sampling end penetrates through the top end of the capacitor base and the bottom end of the angle connector in turn and is connected with the rear end of the copper electrode in the angle connector. The signal lead-out end is connected with the zero potential point GND outside the capacitor base.

Description

technical field [0001] The invention relates to the field of online monitoring of sewage treatment, in particular to a casing end screen signal adapter used in sewage treatment. Background technique [0002] With the rapid development of technology, the degree of automation and electrification in all walks of life has been greatly increased. A large amount of electrification equipment is also invested in the field of sewage treatment. However, in the process of sewage treatment, there are many contacts with water sources and pollutants. Some electrical components, especially transformers, often fail. Among them, insulation failures account for a relatively high proportion. The main reason is that the insulation is weak. Insulation aging and failure caused by partial discharge, eventually leading to insulation breakdown of the transformer. The partial discharge detection of the transformer can reflect the insulation status of the transformer in advance, and can find the insu...

Problems solved by technology

No matter the external type, built-in type or normal grounding type, they are grounded at the end screen of the bushing nearby or connected to the ground through the ground cover and ground cap. Therefore, it is necessary to untie the grounding of the end screen and connect the end screen of the bushing to the testing equipment for detection. The process is cu
