Improved structure of short message terminal device of low voltage power distribution cabinet

Abstract

The invention discloses an improved structure of a short message terminal device of a low voltage power distribution cabinet. A contact type temperature sensor is respectively installed on the conductor surface of the position where an each phase low voltage outgoing cables is connected with the lower end of a recovery time objective (RTO) fuse protector, a water level sensor is installed under the bottom of the power distribution cabinet, the contact type temperature sensor and the water level sensor are connected with a microcontroller, the microcontroller is connected with an alternating current contactor coil through a relay, and simultaneously the microcontroller is connected with a global system for mobile communications (GSM) wireless module circuit. When a numerical value of the temperature sensor on the surface of a low voltage outgoing cable conductor exceeds the upper limit and the maximum, short message early warning and disconnection of the alternating current contactor coil are respectively used, the purposes of real-time short message monitoring of field device failure and automatic disconnection of a failed device power supply are achieved, and water pumping of a submersible pump can be controlled.

Description

technical field [0001] The invention relates to an improved structure of a short message terminal device of a low-voltage power distribution cabinet. Background technique [0002] At present, in the construction of rural smart grids, most of them use remote GPRS devices to realize data collection and remote control technology to achieve the purpose of remote monitoring. However, in some technical aspects, it is still not possible to use a remote control device to troubleshoot equipment, that is to say, maintenance personnel still need to organize on-site repairs. Therefore, developing a method that can not only control equipment failures in real time, but also organize personnel to eliminate defects on the spot in time is the current work mode that power supply companies pursue with less investment and more efficiency.
