Abstract

The application discloses a simulation transformer wire connection detection method and system. The system comprises a power supply device, a detection circuit and a decision circuit. The power supply device is connected with each lead separately for outputting different electrical signals to each lead. A plurality of input ends of the detection circuit are connected with a plurality of the connection terminals respectively for detecting the electrical signals transmitted to the connection terminals through the leads. The decision circuit is connected with a plurality of output ends of the detection circuit for comparing the detected electrical signals of the plurality of the connection terminal with a corresponding preset value and determining the connection condition of the leads on the plurality of the connection terminals according to the comparison result. According to the system, in the training process, trainers can simulate the wire connection process, and the existing problem that the training process cannot be performed through a real high-voltage metering cabinet can be solved.

Description

technical field [0001] The present application relates to the technical field of high-voltage measuring equipment, in particular to a method and system for detecting lead wires of simulated transformers. Background technique [0002] During normal power supply, the power supply company needs to install ammeters for high-voltage metering users. Meters are usually installed in substations or users’ power distribution rooms. Send a small current to the ammeter for measurement, and install and check the main working connecting wires of the ammeter. If the installation is wrong, it will cause accidents or double measurement errors, which will seriously affect the safety of electricity consumption and the settlement of electricity bills. Therefore, the power supply company actively carries out such training work internally to train employees to connect correctly. [0003] Since such training work is not allowed on site, the training is generally carried out in classrooms or spaci...
