At present, in order to ensure the correct correspondence between the electric meter and the power supply incoming line, when the electric meter is installed, the power supply line is numbered, or the wire bundles of different colors are used. After the number of electric wires is too large, it is difficult to distinguish the incoming lines of different users, which is very difficult. It is easy to cause the serial number of the so-called user meter incoming line
Once the serial number is generated, when correcting the power supply line, you can only use manual methods, upstairs and downstairs, to check and screen the lines one by one. The workload is heavy and it is very troublesome.
Existing inspection lines for home-entry crossing errors are checked manually, and the floors are not high or there are not many users, so it is easier to distinguish
If you encounter high-level and many user lines, it will be more difficult and time-consuming to distinguish, and you can only use experience to judge

Embodiment Construction
[0017] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.
[0018] Such as figure 1 As shown, a line entry error prevention detector of the present invention includes a signal detection head and a signal receiver;
[0019] The signal detection head is used to send out the carrier signal of the user to be detected, and change the current and power factor cosΦ of the user line to be detected at the same time, and send the information to the signal receiver;
[0020] The signal receiver is used to receive the carrier signal sent by the signal detection head and the current and power factor cosΦ in the subscriber line.
[0021] Wherein, the signal detection head is a line carrier generator with a specific value of reactive powe...

The invention discloses a line home-entry error-proof detector, and the detector comprises a signal detection head and a signal receiver. The signal detection head is used for transmitting a carrier signal of a to-be-detected user, changes the current and power factors cos(phi) of a to-be-detected user line at the same time, and transmits the information to the signal receiver. The signal receiver is used for receiving the carrier signal transmitted by the signal detector, and the current and power factors cos(phi). The detector provided by the invention facilitates the maintenance operation, is easy to use, and improves the work efficiency. Only if the signal detector of equipment is inserted into a socket at home with a connection error, the meter side at the bottom can receive the user number at which the signal detector is located through the signal receiver and a circuit carrier signal, and then detects the changes of other electric quantity parameters of a meter line, and whether a meter is correctly connected to the user number or not can be judged instantly.
Description
technical field [0001] The invention relates to a line entry error prevention detector and a detection method thereof. Background technique [0002] The power supply system of residential quarters or high-rise buildings generally adopts the power supply metering method of centralized meter boxes. One or more meter boxes are used to centrally place the power supply metering meters of each user, and then the meters of each household are respectively output to supply power to users on each floor. , The ammeter installed by each user must correspond to the user's power supply line one by one, and there must be no slight mistake. At present, in order to ensure the correct correspondence between the electric meter and the incoming power supply line, when the electric meter is installed, the power supply lines are numbered, or wire bundles of different colors are used. When the number of electric wires is too large, it is difficult to distinguish the incoming lines of different use...
