TECHNICAL FIELD
[0001] The present application relates to the technical field of string household detection in power systems, in particular to a non-live string household detection device and a simple test method. BACKGROUND
[0002] In the power supply acceptance detection of newly-built communities, due to the lack of supervision during the implementation of the project, the problem of string household of electric energy meters frequently occurs after the delivery of new houses.
[0003] Common string households can be divided into several cases: live wire string household, zero line string household, and zero-live wire string household. Moreover, the actual string household cases are more diverse. The traditional detection method can detect most string household problems, and some string household cases such as zero line string household may not be detected. Zero line string household does not affect normal power use under normal circumstances, but the situation where the live wire is electrified and the zero line is disconnected may occur. In this case, the user cannot use electricity normally, and the zero line electrification is easy to cause electrical appliances to burn out or electric shock danger.
[0004] However, in the current on-site acceptance, the method of acceptance after power-on is often used. After power transmission, whether the corresponding user's switch is electrified or not is determined to judge the string household. This method can simply determine the correspondence between the switch behind the meter and the user's house, but it cannot determine the correspondence between the switch behind the meter and the meter, and it also needs the cooperation of two people to complete the work. At the same time, this method cannot be effectively controlled, and cannot guarantee the completion of the string household detection work.
[0005] Therefore, a more simple and suitable detection device and method are needed to meet the rapid detection of string household, guide and control the on-site work, eliminate the string household behind the meter, complete the string household detection by one person, ensure the effectiveness of the string household detection work, and construct the substation topology relationship under the condition that the substation is not powered on to assist the establishment of the substation topology.

The three-level switch includes a meter box switch, a branch switch and a total branch switch, and the topological relationship includes the topological structure relationship of total branch switch-branch switch-meter box-electric meter. A kind of not electrified household detection device and simple test method, comprising the following steps: A, during the household test, the power module includes the electric meter in the pre-stored power area file in the communication white list and arranges in order; B, the power module sends the electric energy meter opening and closing protocol of the user corresponding meter according to the electric meter order in the communication white list, and the user upper end meter completes opening and closing; C, the power module sends the electric energy meter opening and closing protocol of the user corresponding meter according to the electric meter order in the communication white list, and the user upper end meter completes opening and closing; D, the induction module detects voltage change at the corresponding user of the specified electric meter, judges whether household is connected, Further, step C achieves detection control, and the operator is guided to the corresponding user's home through the user communication file list, and records are ensured to be checked throughout the process.

[0015] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative effort belong to the scope of protection of the present application.
[0016] As shown in Figure 1 A non-live string household detection device, comprising: a power module, an induction module.
[0017] The power module provides starting voltage for the user meter at the lower end of the transformer outgoing line, and sends the opening and closing protocol of the electric energy meter to the meter in the file to close the meter of the measured user after obtaining the transformer file. Further, the transformer file includes meter number and user address, which is used to verify whether the field meter and the user correspond. Further, the induction module records the topological relationship by the opening and closing of the transformer three-level switch from bottom to top and the power-on and power-off of the electric energy meter after the string household test is completed, wherein the three-level switch includes the meter box switch, the branch switch and the total branch switch, and the topological relationship includes the topological structure relationship of total branch—branch—meter box—electric meter. A non-live string household detection device and a simple test method, comprising the following steps: A. During the string household test, the power module includes the electric meter in the pre-stored transformer file in the communication white list and arranges them in order; B. The power module directs the induction module to the corresponding user of the electric meter according to the order of the electric meter in the communication white list; C. The power module sends the electric energy meter opening and closing protocol of the meter corresponding to the user according to the specified order of the electric meter, and the upper end meter of the user completes the opening and closing; D. The induction module detects the voltage change at the corresponding user of the specified electric meter to determine whether there is a string household, As shown in Figure 1 The power module and the induction module communicate remotely, and the power module automatically reads the key after importing the transformer file. The transformer file includes meter number, user address and other information. The user order is arranged in sequence according to the file address, such as 101, 102, 201, 202, 301, 302, and is synchronized to the operation interface.
[0018] Further, before the test, the total outlet switch, branch switch, meter box switch and post-meter switch need to be closed. If you want to test whether 102 households are connected, the sensing module selects the user, and in the lower interface, the "connected household identification" is operated. At this time, the power module sends the opening and closing protocol to the corresponding electric energy meter in the file of 102 households, and the voltage change and the corresponding communication protocol are obtained by the sensing module behind the user to determine whether the 102 user now matches the corresponding electric energy meter in the file.
[0019] Further, in step B of the detection method, the branch switch, meter box switch, post-meter switch and user switch need to be closed at the same time, so that the power module communicates with the meter carrier wave, and the subsequent entry detection is facilitated, and the protocol of the power module reaches the electric energy meter side.
[0020] As shown in Figure 2 , in step B of the detection method, detection control is achieved. The operator is guided to the corresponding user's home through the user communication file list, and records are kept to ensure that the whole process is recorded and can be checked. For example, after testing whether 102 households are connected, the test record is displayed in real time through the sensing module.
[0021] Further, in step C of the detection method, the sensing module can simultaneously determine whether the transformer area file, meter and user relationship are correct. For example, after testing whether 102 households are connected by this method, if there is no connection, the file, meter and user are all corresponding. If there is a connection, it is determined that there is an error between the file, meter and user. Further detection is performed on the meter corresponding to 102 households, i.e., it is determined whether the meter side or the file is wrong.
[0022] Further, the meter box switch, branch switch and total switch are gradually opened and closed, and the corresponding opening and closing records are combined to complete the topology relationship. First, the total outlet switch, branch switch and meter box switch are recorded during the power connection process, so that the power module is connected to the meter box. At this time, the household meter relationship is tested through the on-off test of the post-meter switch. Then, after the household meter relationship test is completed, the meter box switch is disconnected. At this time, the electric energy meter opening and closing protocol cannot be sent to the electric meter in the meter box, and the relationship between the meter box and the electric meter is determined. The branch switch is opened and closed, and the electric meter under the disconnected branch switch cannot execute the electric energy meter opening and closing protocol, so that the topology relationship between the branch and the meter box is confirmed. The total outlet switch is opened and closed, and the electric meter under the disconnected total outlet switch cannot execute the electric energy meter opening and closing protocol, so that the topology relationship between the total outlet and the branch is confirmed. In order to more specifically describe the recording method of the topology relationship, combined with Figure 3To give a more specific explanation, for example: after the household connection test is completed, the meter box switches and branch switches can be opened and closed step by step from bottom to top to confirm the topological relationship. That is, the meter box switch of unit 1, building 1, on the 1st floor is disconnected. At this time, 101 and 102 are powered off, and the power module's electric energy meter on-off protocol cannot be issued. Confirm and record the subordinate topological relationship of the meter box. After closing the switch, the meter box topology is completed. Continue to disconnect the meter box switch of unit 1, building 1, on the 2nd floor. At this time, 201 and 202 are powered off. After closing the switch, record the subordinate topological relationship of the meter box; gradually complete the opening and closing of all meter box switches. After confirming the topological relationship of all meter boxes, gradually disconnect the branch switches, that is, disconnect the branch switch of unit 1 in building 1. At this time, the meters corresponding to meter boxes 11-1, 11-2, 11-3, and 11-4 are powered off, and the subordinate topology of the branch switch of unit 1 in building 1 can be determined. Then, the branch switches of unit 2 in building 1 and unit 1 in building 2 are gradually opened and closed to complete the ownership judgment of the corresponding meters. Repeat this step until the main outgoing line switch is opened and closed, and the topological relationship between the main outgoing line-branch-meter box-meter can be established to draw a complete substation topology structure.
[0023] In summary, compared with the existing technology, a non-powered cross-household detection device and a simple testing method complete the cross-household detection by sending an opening and closing protocol to the designated meter through the power module, and the power module itself provides an isolation voltage to provide a basic voltage value to the lower-end meter to complete the meter's own opening and closing operation, thereby corresponding the user address in the file to the meter one-to-one, and combining the topological relationship of the opening and closing records of the three-level switches in the substation to complete the cross-household detection.
