Abstract

The invention relates to the field of monitoring and alarm technology, and more particularly to a low-voltage substation leakage monitoring and alarm system and a monitoring and alarm method thereof.The low-voltage substation leakage monitoring and alarm system comprises a monitoring unit, a control unit and an alarm unit which are connected in sequence. The monitoring unit is used to transmit amonitored leakage current to the control unit. The control unit is used to transmit the processed leakage current data to the alarm unit. According to the invention, the real-time monitoring of the leakage current can be implemented through the setting of the monitoring unit, the setting of the control unit is beneficial to judging and processing the monitored leakage current, the judged result istransmitted to the alarm unit, and the alarm unit sends an alarm message to a corresponding operation and maintenance equipment owner so that the corresponding operation and maintenance equipment owner can conveniently know the leakage of a low-voltage substation in time and the operation and maintenance personnel can be organized to conduct troubleshooting to eliminate potential safety hazards.

Description

technical field [0001] The invention relates to the technical field of monitoring and alarming, more specifically, to a low-voltage substation leakage monitoring and alarming system and a monitoring and alarming method thereof. Background technique [0002] Leakage of low-voltage substations occurs from time to time in the current power supply system. In many cases, the leakage of low-voltage substations is not discovered until social personnel or livestock are electrocuted and an accident occurs, which poses a great potential safety hazard. According to the requirements of the network and provincial companies for preventing personal electric shocks of social personnel, and the actual situation of our low-voltage substation leakage from time to time, in order to better prevent the leakage of low-voltage substations from causing personal electric shocks to social personnel, the development of "low voltage Substation Leakage Monitoring and Alarm System” enables operation and m...
