Description

Technical Field

[0001] The utility model relates to the technical field of electric power monitoring, in particular to a low-voltage power distribution fault monitoring device. Background Art

[0002] As people's living standards continue to improve, electricity consumption is increasing, and with it comes higher and higher requirements for electricity services from customers. The current process for reporting fault tripping information for low-voltage users is as follows: When a tripping power outage occurs in a low-voltage user's home, the user should first contact the community property company. After the property company's electrician conducts a preliminary on-site investigation, the user will feedback the information to the customer manager of the power supply company or call 95598 to report the problem. The customer manager and the 95598 specialist will then feedback the information to the operation and maintenance personnel of the power department. The operation and maintenance personnel will receive the information and arrive at the site. According to the content of the repair report, they will conduct a fault point investigation. There are 5 stages from the occurrence of the tripping to the investigation of the fault point, which takes an average of 1 hour and 40 minutes.

[0003] With this reporting method, the low-voltage users under the low-voltage distribution system are out of power and are not monitored. The power supply department cannot obtain the information of tripping and power restoration on the low-voltage residential user side in the first time. In addition, when a low-voltage circuit breaker trips, the operation and maintenance personnel cannot accurately determine the location of the fault point, and it takes a lot of time to find the fault point. The troubleshooting speed does not meet the user's expectations, resulting in a long time for fault handling. Utility Model Content

After the monitoring program is burned to the program chip 44, the USB to TTL connection communication between the computer and the device is made through the program chip 44 to modify the built-in information of the device. After the burning is completed, the low-voltage power supply system is monitored. When a power outage occurs due to a fault, the communication module 43 comes out of the sleep state. Under the action of the CPU, the power outage signal is analyzed and processed to find the fault point, and then the instruction is transmitted to the communication module 43.

At the same time, the power supply mechanism 3 is set to supply power to the lithium battery 32 through the charging port 31, so as to power the device when a power outage occurs. When the device needs to be repaired, the cover body 5 is pressed to make the polyethylene cover body 51 deformed by force, and the clamping part 15 is separated from the clamping part 2 53, and the cover body 5 can be removed from the top of the shell body 1 for inspection, so that its disassembly is more convenient.
