Urban and rural ring network interval switch condensation remote monitoring system

Abstract

The present invention provides a remote monitoring system for dew condensation in urban and rural ring network interval switches. The contacts lead out from the signal terminal row to a communication acquisition module, the output of the communication acquisition module is connected to a wireless communication module, and the wireless communication module is wirelessly interconnected with the system service station; multiple switch cabinets can be connected through their own wireless communication modules Realize wireless interconnection; the advantage of the present invention is: the condensation signal is wirelessly interconnected to form a network operation. When the signal cannot be transmitted in time, the signal can be transmitted indirectly through the nearest switch cabinet to avoid signal miss, and the signal can be transmitted in time. For debugging, the investment is less but the effect is better than the traditional wireless transmission device, which can greatly save the manual debugging time of personnel and improve the reliability of the equipment.

Description

technical field [0001] The invention relates to the field of electric power facilities, in particular to a remote monitoring system for dew condensation of urban and rural ring network interval switches. Background technique [0002] At present, SF6 switches have been widely used in substations, urban and rural distribution networks and other fields. When selecting sites for ring network switches in substations and urban and rural distribution networks, factors such as geological structure and line corridors are often considered, and whether the equipment is prone to moisture is often ignored. . If the switch room is often in a humid environment, the continuously emitted moisture will easily form condensation, and long-term operation will cause the equipment shell and interior to corrode, which will not only reduce the operating performance of the equipment itself, but may cause equipment damage, and in severe cases may cause large-scale power outages. At present, most swit...

Problems solved by technology

[0003] However, the current monitoring and debugging methods for condensation alarm signals are not perfect, especially now that the number of ring network switches in each power supply area is huge, and it is difficult for inspection personnel in areas with weak signals to adjust in time
