Infrared thermal imaging is the industry an increasingly detection technology, general factory inspection application, main To improve the equipment operation reliability, industrial safety and energy saving for the purpose of. Factory equipment composed of electrical and mechanical, and with the application of electrical equipment detection is most to use. Also include rotation, detection of mechanical transmission device, furnace wall And the pipeline fire and heat insulation layer (insulating / cold) state detection.
Application of electrical equipment detection The low-grade damage to equipment harm and stop production, high -grade damage while in the occurrence of electrical fire. At the beginning of the different electrical equipment with electrical equipment detection of IR LED.
Detection work:
Including design, manufacture, installation and operation and maintenance work improperly will cause overheating problems electrical equipment; electric equipment Especially. the bad performance of conductivity, insulation, will bring abnormality detectable. The common causes of overheating
1, the contact resistance is too high: screw loosening or slide fastener, imbedded, oxidation, poor contact or contact area of less than the original to draw resistance is too high.
2, leakage or discharge: due to the equipment insulation is bad, such as along the surface pollution, humidity is too high, the insulation Degradation, lack of insulation from the many other factors, or over voltage.
3, overload: due to incorrect design planning, protection device of arrhythmia, or power supply demand overload and other factors will result is too more. The whole equipment load, high temperature.
4, design and construction: eddy current overheating due to improper, found in the actual detection, overheating due to eddy current should be to high.
5, poor heat dissipation slot: such as cable is too dense, air conditioning is insufficient accumulation of substation, the cabinet body ventilation adverse, equipment environment High temperature factors lead to overheating accumulated heat can not be eliminated, and speed up the insulation aging.
6, other reasons.
Detection of mechanical equipment
The heat source of rotation and drive mechanism from the “friction heat”, due to poor lubrication or component lead to mismatch and other factors, will have a lot of friction heat, causing the temperature rise, resulting in rapid mechanical grinding Loss damage or excessive vibration, the transmission efficiency decline lead to achieve precise control requirements. This kind of detection applications include electric Machine, bearing, coupling, pump, compressor, transmission device (a belt, a gear or chain) and other equipment.
Types of electrical Detection equipment By power plants, electric power transmission and distribution lines, substation, electrical room, control room, slot, distribution box and electrical equipment is Partition places, may include generator, overhead transmission line, transformer, circuit breaker, current transformer, voltage transformer, lightning arrester, the ratio set Tube, bus, reactors, capacitors, cables, wires, and all kinds of switch, switch, relay, or electricity The machine and the power equipment itself, may be the application of test to find out the abnormal issues important equipment.
