Embodiment Construction

[0010] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0011] figure 1 It is the principle block diagram of the shore power supply power unit debugging system. The shore power supply power unit debugging system includes power unit, shore power system simulation tester, voltage regulating transformer, voltage stabilizing transformer, AC contactor KM1, KM2 and KM3, debugging power supply and Reactor; the debugging power is connected to the AC contactor KM1 and KM3, and then connected to the voltage regulating transformer by KM1 and then connected to KM2. After the cable is connected to the inlet end of the shore power unit, the output end of the power unit is connected to the reactor; the shore power system simulation tester is connected to the power unit through optical fibers and cables, which has both high electrical isolation and high resistance The electromagnetic interference performance can detect the...

Abstract

The invention specifically relates to a power unit debugging system of a shore power supply. The system comprises a power unit, a shore power system simulating testing instrument, a voltage regulating transformer, a voltage stabilizing transformer, an AC contactor, a debugging power supply and an electric reactor; the AC contactor is used for controlling the connection and disconnection of a main circuit input line; the voltage regulating transformer is used for changing output voltage; the voltage stabilizing transformer supplies a safe and stable voltage source to the power unit; the electric reactor is used for detecting reactive current and testing load with energy conservation; the shore power system simulating testing instrument is used for detecting various fault points, settings of related parameters, various protections, and starting and stopping of the power unit, as well as PWM (Pulse-Width Modulation) wave sending. With the adoption of the power unit debugging system of the shore power supply, the debugging and inspection of the power unit of the shore power supply are realized, the damage rate of the power unit is reduced, the quality factors of each power unit of the shore power supply are increased, the overall efficiency of the shore power supply system is improved, and the stable running of the shore power supply is ensured.

Description

technical field [0001] The invention relates to a power unit debugging system, in particular to a shore power supply power unit debugging system. Background technique [0002] According to the technical conditions of the ship's power consumption and the high-voltage boarding standard, the quality requirements of the shore power supply are relatively high. As the core of the shore power supply, the power unit is related to the power supply quality and operation stability of the entire shore power supply. However, the shore power supply is a new product and new technology. In this field, there is no special debugging system for the power unit of the shore power supply, and it is impossible to fully detect whether the power unit of the shore power supply meets the design requirements before being powered on. Contents of the invention [0003] In order to improve the debugging process of the power unit, improve the quality of the power unit and the stability of the whole set ...
