Full-automatic mining comprehensive protector testing system

Abstract

The invention discloses a full-automatic mining comprehensive protector testing system, which comprises a hardware and a software, and is characterized in that: the hardware comprises a voltage stabilizer, a testing table and a special box which corresponds to the model of the comprehensive protector one to one; the testing table comprises a programmable control signal generator and a control computer; the programmable control signal generator is connected with a relay; the generator and the relay are connected with the voltage, current measuring block, a switch input output module and a timing module; the three modules are connected with the control computer through RS485 bus, and are used for controlling the computer to connect a printer simultaneously; the software is mainly portioned into user interface module, system maintenance module, task management module and comprehensive testing module. The full automatic mine comprehensive protector testing system has the characteristics of capability of reducing work intensity of testing personnel, increasing testing accuracy and error operation, so that the problem of influence on production and safety caused by untimely and inaccurate testing of comprehensive protector is solved.

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...

AI Technical Summary

Problems solved by technology

[0005] Before 2000, the testing methods for comprehensive protectors in the coal mine production line were backward, there was no special comprehensive protector test equipment, and pure manual testing was used, with incomplete test items, large test errors, and low test efficiency.

Due to the large number of protection plug-in applications in coal mine production, it often occurs that the comprehensive protector test takes a long time and delays underground production. Under the conditions of high-volume production tasks in coal mines, this phenomenon often causes underground electrical equipment to break away from the comprehensive protector.
