Three, summary of the invention

The purpose of this utility model is to provide the lifting electromagnet switch board intelligence verifying attachment of a kind of applicable Alternating Current Power Supply and two kinds of pattern switch board inspections of storage battery power supply.

The technical solution adopted in the utility model is: lifting electromagnet switch board intelligence verifying attachment comprises major loop and control loop, major loop by 380V three-phase alternating-current supply after circuit breaker Q F1, connect inspection switch board through A.C. contactor KM10 normally opened contact again, A.C. contactor KM10 coil is connected in AC power through auxiliary reclay KA20 normally opened contact; 380V three-phase alternating-current supply connection transformer TC1, transformer TC1 output 220V AC power connecting valve power ps 1, Switching Power Supply PS1 output+12V ,-12V direct supply are powered to current transducer H1, H2, current transducer H1, H2 output is connected to the expansion module of PLC controller, through current transducer H1, H2, be connected to switch board to be checked by shunt RS two ends extension line; Control loop is powered to PLC controller by Switching Power Supply PS1 output+24V, 0V direct supply, and PLC controller input end connects button and switch, and output terminal connects pilot lamp, hummer and auxiliary reclay coil.Intelligence verifying attachment adopts PLC and Control automatic circulating operation under Alternating Current Power Supply pattern and storage battery power supply pattern, and automatically switches between two kinds of patterns.Suction under Alternating Current Power Supply pattern, blowing, work some cycles, automatic cutting-off controlling cabinet communication power supply afterwards, and access power failure protector magnetic pattern is carried out suction, blowing, works some cycles.And then recover switch board Alternating Current Power Supply pattern, and carry out suction, blowing, work some cycles.Carry out by that analogy automatic cycle.This intelligent verifying attachment adopts pilot lamp to show work at present state.Adopt current transformer to detect the duty of switch board.If no current is operation irregularity, verifying attachment alarm equipment alarm, switch board quits work.Checking system panel arranges two counters and indicates Alternating Current Power Supply and battery-driven work period number of times.One key testing button is set, can automatic each circulation primary Alternating Current Power Supply and two kinds of lower work periods of pattern of storage battery power supply.Digital display ammeter is set, and whether monitoring checking system exciting current is consistent with switch board exciting current.Pause button, manually control, automatic cycle change-over switch and manually suction, blowing switch are also set simultaneously.

The utility model modern design, multiple functional, the blank of having replenished this type of intelligent checking system, is worth applying widely.

Four, brief description of the drawings

Fig. 1 is electrical schematic diagram of the present utility model.

Five, embodiment
