Embodiment Construction

[0023] Combine below Figure 1 to Figure 7 The schematic diagram specifies the present invention:

[0024] The present invention mainly installs contact temperature sensors on phases A, B, and C of the low-voltage outlet cables at the lower end of the RTO fuse in the low-voltage power distribution cabinet to connect with the short message terminals RT1, RT2, and RT3, and the relay output part JP1 is connected with the coil of the 250A AC contactor , when the value of the skin surface temperature sensor of the low-voltage outlet cable conductor exceeds the upper limit, after the data is processed by the microcontroller, the GSM wireless module circuit sends a short message. If the value of the temperature sensor on the skin surface of the low-voltage outgoing cable conductor exceeds the limit, after data processing by the microcontroller, the AC contactor coil is first disconnected, and at the same time, the GSM wireless module circuit sends a text message to realize that the f...

Abstract

The invention discloses an improved structure of a short message terminal device of a low-voltage power distribution cabinet. Contact temperature sensors are respectively installed on the conductor surfaces of the low-voltage outlet cables of each phase at the connection with the lower end of the RTO fuse, and a water level sensor is installed under the bottom of the power distribution cabinet. The type temperature sensor and the water level sensor are connected with the microcontroller, the microcontroller is connected with the AC contactor coil through the relay, and the microcontroller is connected with a GSM wireless module circuit at the same time. In the present invention, when the value of the temperature sensor on the skin surface of the low-voltage outgoing cable conductor exceeds the upper limit and the limit, the short message is used for early warning and the coil of the AC contactor is disconnected, so as to realize the purpose of real-time short message monitoring of field equipment failure and automatic disconnection of the power supply of the faulty equipment, and The submersible pump can be controlled to draw water.

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. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an improved structure of the short message ter...
