Description

Technical field

[0001] The invention relates to a test system, in particular to a fully automatic mine-used comprehensive protector test system. Background technique

[0002] Comprehensive mine protector, referred to as comprehensive protection, is to protect electrical equipment including power supply and electricity consumption in coal mines. It has overcurrent protection, phase failure protection, three-phase unbalance (phase sensitive) protection, overvoltage and undervoltage protection, and insulation Relay protection devices with functions such as monitoring protection, leakage protection and lockout protection are often plugged into the switch as parts of the electrical switch, so they are generally called plug-ins on site.

[0003] The coal mine comprehensive protector is mainly used to protect various electrical faults that may occur in various electrical equipment in the mine, prevent equipment damage and personal injury accidents, and avoid coal mine gas explosion accide...
