Off-line test method of potential energy recovery device

Abstract

The invention discloses an off-line testing method of a potential energy recovery device. A testing system mainly comprises two parts, namely a mechanical system and an electrical system. A program isincluded therein, and various detections can be automatically completed. The mechanical system mainly comprises three parts, namely a platform support, a gravity simulating mechanism and a hoisting mechanism. The electrical system mainly comprises an industrial 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. By a scientific testingand commissioning method, the potential energy recovery device is tested offline, equipment can automatically complete testing according to setting of commissioning personnel, and various indexes canbe tested before the potential energy recovery device is actually mounted so as to guarantee that the performance of the potential energy recovery device meets requirements and reduce on-site mountingand commissioning risks.

Description

technical field [0001] The invention relates to the technical field of potential energy recovery, in particular to an off-line test method 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 equip...

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.
