Detection device for electronic release of low-voltage apparatus, and control method

Abstract

The invention relates to a detection device for an electronic release of a low-voltage apparatus, and a control method. The detection device comprises a current and voltage signal port for detecting a to-be-detected electronic release, an embedded touch-control PC, a rising constant-current circuit and a rising constant-voltage circuit for providing rising constant-current and rising constant-voltage signals for a digital signal controller, the digital signal controller, a LAN (Local Area Network) or an external memory and a printer; the embedded touch-control PC transmits parameters pre-stored or set by users into the digital signal controller through a serial port COM; the digital signal controller controls a voltage regulator according to the acquisition result so as to regulate loop voltage and loop current to realize the set voltage regulation result, and the pressure regulating result is transmited to the embedded touch-control PC through the serial port COM; and the embedded touch-control PC inputs a test report into the LAN or the external memory through a USB (Universal Serial Bus) 2.0 and a network interface. Based on the modularized assembling mode, the detection device can detect various different electronic releases (electronic plates), so that detection efficiency is improved, cost on the detection equipment is reduced, detection is more reliable and has better consistency, and the detection device is convenient for management.

Description

technical field [0001] The invention belongs to a detection device, in particular to a detection device and a control method for a low-voltage electric appliance electronic trip unit. Background technique [0002] At present, the known low-voltage circuit breaker releases are divided into magnetothermal and electronic releases.
