Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some, not all, embodiments of the application. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this application.

[0024] Application overview

[0025] The recording of power consumption information is the most important link in power grid construction. Through the electricity consumption information, not only can the future electricity consumption plan be predicted, but also whether there is a fault in the electricity consumption of the corresponding user can be found in time. Therefore, the timeliness and quick response to the statistics of electricity consumption information are two important aspects for the sa...

Abstract

The invention relates to the technical field of power grid safe operation, in particular to a leakage protection method, an electric meter box and a power grid system. The earth leakage protection method comprises the following steps: acquiring first-level electricity utilization information of a first-level user system; comparing the first-level electricity utilization information with preset information to generate a comparison result; judging whether the first-level user system has fault information or not according to a comparison result; and when determining that the primary user system has the fault information, cutting off the power supply of the secondary user system to the primary user system. In the power utilization process of the first-level user system, the first-level power utilization information is detected in real time and compared with the preset information, and when it is determined that fault information exists in the first-level user system according to the comparison result, power supply of the second-level user system to the first-level user system is cut off in time. Therefore, the first-level user system and the second-level user system are separated, and the possibility that the first-level user system interferes with the second-level user system is reduced.

Description

technical field [0001] The application relates to the technical field of power grid safe operation, in particular to a leakage protection method, a meter box and a power grid system. Background technique [0002] Power grid construction is also developing simultaneously with social development, such as from the previous manual meter reading to the current smart meter reading. In the development process of the power grid, the security of the power grid is the top priority. Because the smart meter is also gradually upgraded from a single smart meter reading function, in order to improve the user's electricity safety as much as possible. [0003] In the existing technology, in the field of low-voltage power supply, the electric meter used by the user has the functions of metering, cost control, monitoring, etc., but when a single user's electricity leakage occurs, the smart meter cannot timely feedback the problem, causing the user The group you belong to may all be broken, a...
