Description
Technical field
The utility model relates to a kind of monitoring diagnosis device, particularly the monitoring diagnosis device of high-voltage electrical equipment.
Background technology
The task of the monitoring and diagnosis of high-voltage electrical equipment is that equipment is put into operation with high quality status; Timing in service or incessantly equipment is carried out present situation monitoring to the diagnosing malfunction that is about to produce, can in time be handled and maintenance in good time; Prevent the generation of accident; Avoid causality loss, ensure safety in production and prolong service life of equipment, equipment is increased economic efficiency.At present, high-voltage electrical equipment is main with monitoring mainly, and fault diagnosis is still lacked accuracy, and generally uses with the monitoring system of computing machine as core, and its complex structure, cost are high, specific aim is not strong.
Summary of the invention
The purpose of the utility model provide a kind of simple in structure, programming easily, high efficient and reliable, the monitoring of collection present situation and fault diagnosis be the monitoring diagnosis device of the high-voltage electrical equipment of one.
The technical scheme that the utility model adopts is: comprise each state sensor, each state sensor is respectively voltage sensor, current sensor, temperature sensor, insulation sensor and arc sensor; Each said sensor connects the different input ports of pre-processing module respectively, and the output of pre-processing module connects the A/D modular converter, and the output of A/D modular converter connects PLC, and the different output ports of PLC connect touch-screen, alarm and printer respectively.
The utility model simple in structure, convenient and reliable operation can in time be monitored the generation with tracing trouble.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the structural drawing of the utility model;
Among the figure: 1. voltage sensor; 2. current sensor; 3. temperature sensor; 4. insulation sensor; 5. arc sensor; 6. pre-processing module; 7.A/D modular converter; 8. touch-screen; 9. Programmable Logic Controller; 10. alarm; 11. printer.
Embodiment
Referring to Fig. 1, the utility model comprises each state sensor, is respectively voltage sensor 1, current sensor 2, temperature sensor 3, insulation sensor 4 and arc sensor 5.These sensors are installed in the relevant position of high-voltage electrical equipment, detect voltage signal, current signal, temperature signal, the insulation situation signal of high-voltage electrical equipment respectively and whether have electric arc to produce signal.These sensors are connected the different input ports of pre-processing module 6 respectively, and pre-processing module 6 comprises amplification, filtering and shaping circuit.The output of pre-processing module 6 connects A/D modular converter 7, and the output of A/D modular converter 7 connects PLC 9 (Programmable Logic Controller), and the different output ports of PLC 9 connect touch-screen 8, alarm 10 and printer 11 respectively.PLC 9 is control centers of the monitoring and the diagnosis of whole device, and each sensor is handled the signal that detects through amplification, filtering and shaping, again through input PLC 9 after the analog to digital conversion, output after PLC 9 handles and judges.PLC 9 is through data line while and touch-screen 8 two-way exchange information, and touch-screen 8 provides friendly man-machine interface, and implementation procedure shows and keeps watch on.Touch-screen 8 provides friendly man-machine interface, and implementation procedure shows and keeps watch on the Realtime Alerts situation, is the interchange interface that the user conveniently carries out the direct viewing fault diagnosis; Pass through alarm 10 Realtime Alerts when breaking down; Also can pass through touch-screen 8 direct input fault phenomenons, through artificial judgment, make affirmative acknowledgement (ACK) after; Can confirm failure cause, draw solution.Simultaneously, the operational circumstances of the alarm condition of the monitoring of 9 pairs of faults of PLC and diagnostic result, alarm 10 and touch-screen 8 all can directly be exported through printer 11.
