Description

Negative control terminal and ammeter pairing debugging device

technical field

The utility model relates to a pairing debugging device for a negative control terminal and an electric meter.

Background technique

The load control terminal is the equipment used by the power supply department to monitor and control the electricity consumption of the power consumption unit. The power supply department can directly notify the power consumption unit to carry out load control. When an instruction is issued, the user's load device immediately disconnects the user's main switch, and the load device uses radio to receive the signal from the power supply bureau; when the regional power load supply is tight, the power supply company can implement regional or industrial load regulation authorized by the government to ensure the critical load. It is used in conjunction with the electricity meter for residents' daily life.

In recent years, with the rapid development and advancement of national intelligent network construction, the requirements for the online rate of negative control terminals are getting higher and higher. In order to ensure the online rate of on-site negative control terminals, the work Personnel must rush to the site for terminal debugging. The traditional debugging method is that after the load control terminal is installed, it is debugged after simulating normal operation under load conditions. After debugging, if the host shows that the load control terminal is not online or the collected data has deviations, it is necessary to go back and forth to the work site again. Debugging; as the coverage rate of the negative control terminal is greatly increased, this traditional operation method can no longer meet the work requirements. The main reasons are:

1. To carry out on-site commissioning, the equipment needs to be charged and have a certain load to ensure that the electric energy meter can start normally.

2. The metering devices of some users are installed on the poles and iron towers, which are close to the high-voltage lines. On-site climbing and live debugging are dangerous and may easily cause safety accidents.

3. The load control terminal and the electric energy meter are connected in parallel. If the debugging is unsuccessful, the terminal needs to be disassembled repeatedly, which is prone to wrong wiring of the metering circuit.

4. On-site debugging requires the cooperation of personnel from multiple departments. The door of the metering box and the tail of the electric energy meter need to be unsealed, which leads to a lot of waste of sealed lead.

5. For users who cannot send power in time for new installations, the commissioning personnel must wait for the on-site power transmission before performing terminal debugging after the on-site installation is completed, and it will be time-consuming and labor-intensive to go to the site repeatedly.
