Work overtime to support the construction of key projects

In late May 2020, our company accepted the task of producing intelligent high-frequency DC power cabinets with special specifications, and supplied two sets for a key enterprise in Ningbo located in the Sino-Italian Ecological Park.

　Because user requirements are different from conventional ones, it needs adaptive AC380V dual power switch, color touch screen monitor, single busbar non-segmented DC system, control bus, combined bus total 10 feeders; 3 inverter (AC220V) output, but also The battery pack is inspected and the delivery and installation are required to be completed before the power is delivered to the factory at the end of June, so the design and manufacturing period is short.

　　In the face of insufficient user requirements and data, based on a deep understanding of the relationship between principles and output, we divided functional blocks, quickly carried out panel layout, drawn processing drawings, remanufactured and processed, and implemented the purchase of main parts and accessories; in order to improve reliability It also adds some AC and DC MCBs and indicator lines to create conditions for safe operation.

During the intense production process, the coding machine suddenly failed, which caused the label printing link to be blocked. To ensure the orderly production, we urgently purchased components from the Internet and repaired and replaced them ourselves. The update of the device was completed under the guidance of the online video, and normal print output was realized. …

　　 With the support of many friends and the strong cooperation of the partners, the employees of the company worked overtime. By adjusting unreasonable wiring, setting and calibrating values, standardizing the process, and constantly revising, the construction period can be carried out as planned. But during the aging period on June 19, we received an order requesting us to deliver the goods in advance to June 22, making everyone anxious. Fortunately, everyone worked together and worked together to overcome difficulties and finally completed the final re-school test work late at night on June 21.

At this stage, it was the period of high temperature and high humidity. In order to complete production, we strengthened the environmental protection work for assembly and debugging. Before that, there was heavy rain. By the morning of June 21, the Great Wall Road where the company was located also accumulated water. , The employees come to work by wading through the water. Fortunately, on the afternoon of the 22nd, the weather turned fine, and the water on the Great Wall Road gradually receded. Let us smoothly ship at 14:30, and deliver the two sets of power supplies with the efforts of the employees to the users.
