Description
Technical field
The present invention relates to a kind of detection devices, more specifically, it relates to a kind of Portable movable motor test equipment.
Background technique
In electrical engineering, when relative humidity is greater than 80%, referred to as high humidity.Relative humidity is less than 40 ℅, referred to as low humidity or dry
It is dry.Influence of the humidity to electrical equipment is mainly dielectric strength, fungus growth, metal erosion.
1, influence of the humidity to dielectric strength.Humidity is higher, reduces insulation of electrical installation intensity, and the moisture in air is attached
On the surface of insulating materials, reduce the insulation resistance of electrical equipment, the leakage current of equipment greatly increases, cause insulation hit
It wears, generates electric fault.
2, influence of the humidity to fungus growth.Wet air is conducive to mycotic spore germinating growth.Practice have shown that temperature
It is the fair-weather conditions of mould breeding when relative humidity is 75 ℅ -95 ℅ for 25-30 degree.If air not convection current will make
Fungus growth is accelerated rapidly.Therefore, in the case where humidity is identical, temperature is equal, indoor equipment mildew is tighter than outdoor equipment
It is much heavier.The mildews most serious such as organic fiber product, leather, hard rubber article for containing in electric product.Material itself or table
There is foul in face, just provides necessary nutriment to the growth of mould.After mould is formed, a large amount of moisture is contained in fungal cell,
When mycelia in it is netted be covered with insulator surface when, not only product insulation performance substantially reduces, but also influences equipment appearance and mark.
Mould often secrets out of acidic materials during metabolism.Conductive metal and contact material is set to generate one layer of dark and gloomy film,
Contact resistance is caused to increase.Especially to the printed circuit board of electronic instrument, if long-term place in such an environment can open circuit potential,
By lowering apparatus precision, or equipment fault is caused, or even burns instrument.
3, influence of the humidity to metal erosion.It, will be tight after conductive metal, magnetic conduction silicon steel sheet in electrical equipment are corroded
The performance and used life of equipment is reduced again.After relative humidity reaches certain numerical value, corrosion of metal can be accelerated suddenly.In work
This humidity is called critical humidity by Cheng Shang.Such as 70 ℅ of critical humidity of steel, iron are 63 ℅, copper is 60 ℅.Corrosion causes gold
Category loses due performance.Steel is exactly " the getting rusty " said usually because the character that corrosion occurs changes.
Currently, for the dehumidification mode of electrical equipment, mainly using ventilation and electrically heated mode, wherein ventilation
The scheme of dehumidifying is too simple, usually only equipment some position be arranged an air exhausting device, all air made, all from
Here it is discharged.However, sometimes, for equipment, being provided with the air of the near sites of air exhausting device, humidity is not
Highest so will lead to the higher air of other humidity in the internal circulation of equipment, cause to the lesser part of humidity
It influences.
