Embodiment Construction

[0021] In order to better explain the present invention and facilitate understanding, the following describes the present invention in detail through specific embodiments in conjunction with the accompanying drawings.

[0022] The present invention provides a single-phase multi-channel low-voltage user-side power failure monitoring device, which includes a measurement module, a power supply module, and a communication module. The measurement module is used to monitor the power failure state of a multi-channel single-phase power supply. The communication module is used to The power failure information monitored by the measurement module is reported, and the power supply module provides power for the measurement module and the communication module.

[0023] The measurement module includes a potential transformer (PT), a metering chip, and a single-chip microcomputer (Micro Control Unit, MCU). The external multi-channel AC voltage signal is transformed into an isolated weak signal thr...

Abstract

The invention relates to a single-phase multi-channel low-voltage user-side power outage monitoring device. The single-phase multi-channel low-voltage user-side power outage monitoring device comprises a measurement module, a power module and a communication module. The measurement module is used for monitoring a power outage state of a multi-channel single-phase power supply. The communication module is used for reporting power outage information monitored by the measurement module, and the power module provides the power for the measurement module and the communication module. The single-phase multi-channel low-voltage user-side power outage monitoring device can perform monitoring on up to 15 single-phase power supplies at the same time, and can still maintain normal work and discriminate and report the power outage state in the event of power outage.

Description

Technical field [0001] The invention relates to the technical field of intelligent power distribution and utilization, and more specifically, to a single-phase multi-channel low-voltage user-side power failure monitoring device, which simultaneously monitors single-phase multi-channel power supply voltages, and timely discovers and reports the user-side power failure situation. Background technique [0002] At present, the power outage on the low-voltage user side generally relies on the user's own active reporting. This method cannot detect the power outage in time, which is not conducive to fast and timely repairs, and it cannot accurately count the power supply reliability rate on the user side. To address this problem, the prior art discloses a low-voltage power failure monitoring terminal, which can only monitor three-phase lines, and is not suitable for applications where the user side is mostly single-phase power supply. The prior art also discloses a user power outage mon...
