Urban-rural ring network interval switch condensation remote monitoring system

Abstract

The invention relates to an urban-rural ring network interval switch condensation remote monitoring system, which comprises a condensation sensor module. The condensation sensor module is equipped with two pairs of condensation alarm contacts A and B and a pair of condensation action contacts C; the condensation alarm contact A is connected with a remote communication acquisition module; the condensation alarm contact B is connected with an alarm module and an alarm lamp module; the condensation action contact C is connected with an intermediate relay; and the action contact of the intermediate relay is connected with an operation power circuit of an interval switch heating and dehumidification device. The urban-rural ring network interval switch condensation remote monitoring system has the following advantages that phenomena such as switch miss trip, device abnormality or direct grounding caused by condensation can be effectively prevented, the professional management level of the urban-rural ring network interval switch is improved, and the power supply reliability is enhanced.

Description

Technical field [0001] The invention is a remote monitoring system for the condensation of an urban and rural ring network interval switch, which belongs to the field of power equipment. Background technique [0002] At present, combined electrical switchgear such as ring network cabinets and switching stations have been widely used in the power supply system of urban and rural ring networks. Interval switches are affected by factors such as construction location, geological structure in different regions, underground pipe networks, passages and corridors. Will get damp easily. Although most of the switch rooms currently only rely on the heating and dehumidifying device of the interval switch to heat the condensation into water vapor and discharge it, which greatly accelerates the defrosting efficiency. However, the number of ring network switches in each power supply area is huge. Due to the lack of effective means of monitoring the condensation alarm signal, it is difficult fo...

AI Technical Summary

Problems solved by technology

However, the number of ring network switches in each power supply area is huge. Due to the lack of effective monitoring means for condensation alarm signals, it is difficult for the inspection personnel to know the defrosting effect of each switch room in time, and it is impossible to timely and accurately rush to the places with severe frost and water accumulation. The switch cabinet eliminates the hidden danger of condensation

If the interval switch is often in a humid environment, the continuously distributed moisture will easily form condensation, which will cause long-term corrosion of the equipment shell and interior, which will greatly reduce the operating performance and life of the equipment itself

In addition, if a large amount of condensed water occurs in the cabinet, the operation and maintenance personnel will not be informed of the dampness of the equipment in time to deal with it, which will cause serious short-circuit damage to the equipment and cause large-scale power outages in urban and rural ring networks
