Checking tool for quickly checking corresponding relation between ammeters and users

Abstract

The invention discloses a checking tool for quickly checking the corresponding relation between ammeters and users. An auxiliary engine power supply supplies power to an auxiliary engine central processing unit (CPU), an electric parameter signal emitting circuit and a GPRS communication module I. The electric parameter signal emitting circuit is controlled by the auxiliary engine CPU to emit an electric parameter signal to the load end of a power supply circuit. The auxiliary engine CPU is in communication with a GPRS communication module II of a host through the GPRS communication module I, so as to notify the host of the emitting completion state of the electric parameter signal. A current transformer is connected in series with one outgoing line of an ammeter. The electric parameter signal is acquired by an electric parameter signal acquisition circuit. When the host receives a notifying signal sent by an auxiliary engine, the CPU of the host begins to calculate the acquired electric parameter signal. Therefore, the contra error can be judged. By means of the checking tool, on the premise that the occurrence of power failures and the electric charge increment for users are avoided, the corresponding relation between ammeters and users can be quickly checked. Meanwhile, the checking tool is accurate in determination and high in reliability.

Description

technical field [0001] The invention belongs to a testing tool for electric power, and relates to a checking tool for checking the corresponding relationship between an electric meter and a user. Background technique [0002] Misconnection of electric energy meters is a very common problem of power supply service quality. There are mainly three reasons for the misconnection of electricity meters: 1. The meter box manufacturer makes mistakes in the wiring of the meter box; Wrong line, 3. The developer leads to faltering connection when laying out the household line. At present, in the process of troubleshooting and correcting the problem of meter stringing, the investigators generally use the following two methods: 1. Pull off the main switch of the user from house to house to observe whether there is a change in the current of the electric energy meter; this method affects the normal operation of the customer. Electricity consumption; 2. Use current clamps to measure the lo...

[0002] Misconnection of electric energy meters is a very common problem of power supply service quality. There are mainly three reasons for the misconnection of electricity meters: 1. The meter box manufacturer makes mistakes in the wiring of the meter box; Wrong line, 3. The developer leads to faltering connection when laying out the household line

At present, in the process of troubleshooting and correcting the problem of meter stringing, the investigators generally use the following two methods: 1. Pull off the main switch of the user from house to house to observe whether there is a change in the current of the electric energy meter; this method affects the normal operation of the customer. Electricity consumption; 2. Use current clamps to measure the lower wire of the air-opening, and at the same time increase the load on the user side to observe whether there is a change in current; this method continuously consumes electricity from the user. When checking, the customer uses electricity normally, but increases the user's electricity bill. Cause customer dissatisfaction and unnecessary disputes
