Single-phase meter missort troubleshooting instrument

Abstract

The invention discloses a single-phase meter missort troubleshooting instrument. The instrument comprises an A-type signal transmitting device, a B-type signal receiving device, a box cover and a boxbody, and the outer wall of the top of one side of the box body is rotationally connected with the box cover through a hinge. Partition plates are fixedly connected to the two sides of the inner wallof the box body in a clamped mode. According to the invention, the A-type signal transmitting device and the B-type signal receiving device are arranged, the A-type signal transmitting device is a main control end and the main function is to emit a test signal, the B-type signal receiving device is mainly used for receiving a test signal corresponding to the B-type signal receiving device and displaying a test result, 12 wires and 6 electric energy meters can be tested at the same time, whether the phases of a phase line (live line) and a zero line of each electric energy meter are correct ornot can be detected at one time through each group of bipolar +-signals, and accessories can be sorted and stored through the use of a wire clamp storage area and a net bag in the use process of the missort troubleshooting instrument, so that the troubleshooting instrument is convenient to carry.

Description

technical field [0001] The invention relates to the technical field of one household, one meter engineering in electric power systems, in particular to a single-phase meter serial checking instrument. Background technique [0002] In recent years, with the continuous implementation of rural power grid upgrading projects, the monitoring of the construction process during the project implementation has not been strictly monitored, resulting in frequent occurrence of the problem of electric energy meters being connected to households. Check the work of the household line to prevent the household line from colluding. Clarify the responsibility of the developer or construction unit to check the household line, and require the developer or construction unit to conduct a comprehensive check on each user's household line, and make a record. After installing the meter, carry out the "household verification* inspection to prevent the household meter from being misleading. After the m...

Problems solved by technology

[0004] 1. The current household inspection work is mainly to test and inspect each wire one by one through a multimeter. The method is single and time-consuming. However, the renovation of one meter per household involves a wide range of households. There are as few as a dozen households and as many as nearly a hundred households in each unit. , it takes a lot of time to check through the traditional single method and it is difficult to guarantee the accuracy of the test and check

[0005] 2. The traditional household serial inspection instrument needs to use wires to connect the household line and the inspection instrument. These wires, wire clamps and other accessories are inconvenient to carry, and the storage of accessories after use is messy
