Description

technical field [0001] The present invention relates to the technical field of charging piles, and more specifically, to an online verification device and system for a charging pile master control box. Background technique [0002] The internal wiring of the master control box is complicated. Once a short-circuit accident occurs, sparks will be generated, which will cause a fire and cause a safety accident. Especially after the construction of the main control box is completed, the subsequent inspection and maintenance of the main control box by the staff is complicated, and the structure of the existing verification device is complicated. [0003] For example, the Chinese patent application with the publication number CN104020434B discloses an automatic verification system for low-voltage current transformers for metering, including a turnover box in-out warehouse connection and unstacking device, a loading and unloading module, a conveying line and a set on the conveying l...

AI Technical Summary

Problems solved by technology

However, as the wiring inside the main control box becomes increasingly complex, the monitoring system plays an increasingly important role in ensuring charging safety. The existing technology lacks the verification of the monitoring system of the electric control box, and does not solve the problem of the verification of the monitoring system of the main control box.
