Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and through specific embodiments. The following embodiments are only descriptive, not restrictive, and cannot limit the protection scope of the present invention.

[0032] The present invention takes figure 1 The typical low-voltage topological structure shown is taken as an example. The low-voltage topological structure includes distribution mains 1, low-voltage outlet switch 2, low-voltage cable branch box 3, knife switch 4 and household meter 5. The distribution mains are connected with the first low-voltage outgoing line The switch is connected to the input end of the second low-voltage outlet switch, the output end of the first low-voltage outlet end is connected to the input end of the first low-voltage cable branch box, and the output end of the first low-voltage cable branch box is connected to the input end of the second low-voltage cable branch box. co...

Abstract

The invention relates to a method for verifying a low-voltage topological structure according to a power failure event of a user meter, and the method is characterized by comprising: a user meter actively reporting the power failure event to a concentrator after the power failure of the user meter; an intelligent fusion terminal reading the power failure information in the concentrator, judging afault point according to the power failure information, and tracing back all theoretical power failure user meters; if the power failure user table in the power failure information is inconsistent with the theoretical stop table, generating a topological structure verification work order and then entering the next step, otherwise, ending the verification; and sending the generated topological structure verification work order to a cloud master station for topological structure correction. The method is reasonable in design, can overcome the defect that the low-voltage topological structures are manually checked one by one on site, achieves an automatic checking function of the low-voltage topological structures, and is used for solving the problems that an existing distribution network low-voltage topological structure is not clear and accurate, and time and labor are wasted in manual checking.

Description

technical field [0001] The invention belongs to the technical field of low-voltage power distribution, and relates to a method for verifying a power failure of a household meter, in particular to a method for verifying a low-voltage topology structure according to a power failure event of a household meter. Background technique [0002] The low-voltage distribution network is located at the end of the entire power grid. It has the characteristics of wide distribution, complex power supply environment, and difficult operation and maintenance. It has long lacked intelligent and efficient operation monitoring and operation and maintenance management methods. The low-voltage topology of the distribution network includes distribution mains - low-voltage outlet switches - low-voltage cable branch boxes - knife switches - household meters. Due to problems left over from history, there are still blind spots in the low-voltage topological structure of the distribution network, and th...
