Description

Non-resident household meter identifier and fixing device

technical field

The invention relates to a test instrument with the function of household meter identification, which is widely used in the field of meter installation and acceptance and subsequent customer service, to sort out the relationship between customers and meters, to ensure accurate wiring of low-voltage customers, and to realize the fine management function of customer service. The method provides a reliable guarantee for the accuracy of residential customer files in the upper community, and belongs to the technical field of business file management.

Background technique

Now, with more and more new buildings in the community, during the construction and power transmission process, due to the work of the developer, there are errors in the connection between the customer's meter and the household. During the process of handing over the account, some buildings have been sold and cannot Contacting the head of household leads to the inability to achieve a completely correct verification of the relationship between the household and the meter. In the future, when there are problems such as wrong wiring in the process of using electricity, it is easy to cause customer dissatisfaction, electricity disputes and even customer complaints. At present, the existing traditional household meter identifiers on the market can only be identified when the customer is at home, and the above-mentioned problems cannot be effectively solved.

The traditional serial household identification instrument consists of three parts: a test host, a current clamp, and a test terminal. Add a capacitive load to the test terminal, insert it into the user socket, test the voltage and current waveforms for detection, and the test host judges the affiliation relationship through the APP software. The test host is at the meter box, and each current clamp connected from the host is respectively embedded in the output phase line of each ammeter. By measuring each current signal, analyze which line the test terminal is on, and thus identify the connection between the ammeter and the meter. The corresponding relationship of the user to verify the correctness of the file.

Disadvantages of traditional serial household identification devices:

1) The whole process needs to be tested at each user's home. When conducting a census of users, it is necessary to ensure that there are people in the user's home to conduct the test, and when there are many verified users, it is necessary to ensure and contact each user for file verification, which is not practical.

2) When testing the wiring relationship of household meters, on-site voltage and current wire wiring is required. The operation is cumbersome and there is a risk of electric shock.
