Offline test system of potential energy recovery device

Abstract

The invention discloses an offline test system for a potential energy recovery device, wherein the system is mainly composed of a mechanical system and an electrical system. A program is included inside and can automatically complete each of tests. The mechanical system is mainly composed of three parts including a platform support, a gravity simulation mechanism and a lifting mechanism. The electrical system is mainly composed of an industrial control computer, a variable frequency power supply, a variable frequency motor controller, a torque motor controller, a servo controller, an analog acquisition module, an encoder acquisition module, a digital output module, a digital acquisition module, a load acquisition module, a voltage sensor, and a current sensor. The system can perform an offline test on the potential energy recovery device through a scientific test debugging method, equipment can automatically complete a test according to setting of debugging personnel, testing of various indicators can be completed before actual installation of the potential energy recovery device, so as to confirm that the performance of the potential energy recovery device meets requirements, andthe risk of on-site installation and debugging is reduced.

Description

technical field [0001] The invention relates to the technical field of potential energy recovery, in particular to an offline test system of a potential energy recovery device. Background technique [0002] Large-scale lifting equipment, such as port gantry cranes and container gantry cranes, are high-energy-consuming equipment and there is a large energy waste. In the general environment of energy saving and emission reduction for the whole people, the energy saving problem of such large-scale equipment needs to be solved urgently, and the potential energy recovery device has emerged as the times require. [0003] The potential energy recovery device can store the electric energy generated under the regenerative braking state of the hoisting equipment, release it to provide energy for the hoisting equipment when the hoisting equipment consumes energy, complete energy recovery and reuse, and save energy and reduce consumption. [0004] At present, there is no special equipm...

AI Technical Summary

Problems solved by technology

Professional designers with rich experience are required to complete the process. The process is cumbersome and complicated, and there is a risk of debugging because of failure to test before leaving the factory

On site, it is necessary to capture the working waveform of the potential energy recovery device through high-voltage probes and oscilloscopes, and perform manual calculations, and it is necessary to operate the lifting personnel to operate the equipment to cooperate with the completion of the test and commissioning. The degree of cooperation is high, and coordination is inconvenient, time-consuming and labor-intensive, and it is accompanied by high risks.
