A switch status monitoring device in a substation cabinet

Abstract

The invention provides a technical scheme of a switch state monitoring device in a transformer substation cabinet. The device comprises an I / O port connected with an auxiliary contact of a switch in the transformer substation cabinet, wherein the I / O port is connected with a digital signal processor through a signal modulation module; the digital signal processor is connected with an upper computer through a serial port module; the digital signal processor is connected with a display screen; the digital signal processor is also connected with a wireless communication module; moreover, a power supply module is connected with the digital signal processor. The device provided by the scheme of the invention can monitor the switch state in a switch cabinet in time and transmit the monitoring information to a set mobile phone in time, and can also transmit the monitoring information to the upper computer to remind workers, so that the normal operation of a power grid can be guaranteed.

Description

technical field [0001] The invention relates to a substation cabinet, in particular to a switch state monitoring device in the substation cabinet based on digital signal processing. Background technique [0002] In the prior art, the known technology is that in the power supply network, the substation cabinet is an important link. If the substation cabinet fails, it will affect people's electricity consumption. At present, most of them are manually observed to judge whether there is a fault, or The auxiliary contact of the switch in the substation cabinet is connected in series with the indicator light to judge whether there is a fault, which not only wastes time, but also cannot obtain fault information in time, and the staff cannot repair it in time. This is the deficiency of the existing technology. . Contents of the invention [0003] The purpose of the present invention is to provide a technical solution for a switch state monitoring device in a substation cabinet in...
