Description

Auxiliary device for table-chip relationship tester

This application is a divisional application of a utility model patent application with an application number of 201320835889.6 and an application date of December 17, 2013.

technical field

The utility model relates to a power supply detection device, in particular to an auxiliary device when a table-chip relationship tester is used.

Background technique

At present, it has become one of the important tasks for the power supply department to implement refined management of the transformer station area. Due to the incompleteness of early substation user information, metering device data, underground cables and household line route diagrams, and business orders, and some low-voltage users privately connecting power supply lines, the adjacent transformer substations crossed. The complexity of the lines makes it difficult to determine the transformer and phase sequence of the users in the station area, which directly leads to the inability to implement the assessment of the line loss of the station transformer. The resulting measurement and creditor's rights disputes are common, which directly increases the operating risks of power supply companies. In order to solve this problem, the current power supply department generally uses the station-chip relationship tester to identify the user attributes and phase sequence of the station substation. The station-chip tester is an instrument that uses carrier communication as a communication method to automatically identify the relationship between the station area and the household substation. , can automatically sort out the subordination relationship of household substations in low-voltage station areas, and improve the accuracy of household substation relationship files in the power marketing system. As shown in Figure 1, the TB-2000 chip relationship tester produced by Guangyi Technology Co., Ltd. is used to identify the user attributes and phase sequence of the station substation. The main components of the platform chip relationship tester include the TBT-2000 transmitter host and the TBR2000 handheld extension and 4 test lines with clamps. During the test, after the tester boards the bench, clamp one end of the terminal clamp of one of the two test lines of the transmitting host to one of the busbars on the low-voltage side of the distribution transformer to be checked. On the first phase line (such as A phase line), clamp one end of the other terminal clamp to the neutral line (N line) of the busbar on the low-voltage side of the distribution transformer to be inspected; turn on the power of the transmitter host, and the host enters the carrier signal sending state ;Clamp the two test wire clamps of the handheld extension to the corresponding phase wire and N wire at the inlet of the meter box at the user end, and after a few seconds, the LCD screen of the handheld extension will display the phase to which the user belongs. Change the number with the host station, so as to determine the station-area relationship of the measured electric power households. If the hand-held extension prompts that the signal is out of range, the test point does not belong to the station area.

When using the table relationship tester for testing, the tester must use a foot buckle or a lift car to climb onto the bench when the line is live, and clamp the wiring clip to the low-voltage side busbar of the transformer for measurement. Since the work is live , and the position of the bench from the ground is high, the range of activities available on the bench is small, and there are a lot of unsafe factors for the testers during the test; moreover, the testers need to carry out 2 steps on the stage and off the stage during the test Work, time-consuming and labor-intensive.
