I. Product Introduction

1.1 Product Overview

In the Handover Test and Preventive Test of Electric Equipment, The Low-Voltage Test Items of Circuit Breakers Usually Include Mechanical Characteristic Test and Loop Resistance Test. In Order to Complete the Test Task, It Is Usually Necessary to Carry Two Sets of Equipment for the Test. Even if a Few Devices Support Two Test Functions, Most of Them Can Only Perform Single-Phase Loop Resistance at a Time. The Wiring and Operation Are a Bit Cumbersome, And the Work Efficiency Needs to Be Improved.

The Design Team of This Machine Has Many Years of On-Site Work Experience, And Has a Full Understanding of the Above-Mentioned Actual Situation. Through Hardware Design and Software Optimization, A Set of Solutions Is Proposed in a Targeted Manner. On the Premise of Retaining the Realization of a Single Test Function, An Innovative Intelligent Test Mode Is Realized. This Mode Not Only Meets the Testing Requirements on Site, But Also Greatly Simplifies the Wiring and Operation, Supplemented by the Real-Time Broadcast of Human Voice and the Blessing of Wireless Control of Smart Devices, Making the Test Process More Concise, Convenient and Efficient.
