Up-draught can produce a large amount of air-flow for having positive and negative charge, the charging neutrality of institute's band on object can be fallen.Work as body surface
Institute it is electrically charged be negative electrical charge when, it can attract the positive charge in air-flow；When it is positive charge that body surface institute is electrically charged, it can be inhaled
Negative electrical charge in bleed stream.When equivalent positive and negative charge contacts, that is, it can reach electrical neutralization, it thus can be in clear switch cabinet
Some positions are electrically charged in switchgear caused by electrostatic and shelf depreciation.
The heating-up mechanism includes the air inlet cylinder being arranged below the air inlet of the minitype ion blower, in the air inlet cylinder
Resistive heater is set.Heating-up mechanism is the temperature increased in switchgear, and the temperature difference of such air and temperature lowering board is bigger, more
It is converged on temperature lowering board conducive to aqueous vapor.Heating-up mechanism is heated up using resistive heater, and resistive heater uses the electricity of small volume
Silk is hindered, by atmosphere temperature rising in air inlet cylinder, the air to heat up under the action of minitype ion blower enters air inlet, and to
Upper movement, finally to heating up in switchgear.
To in the charge progress at certain electrification positions when the present invention can eliminate electrostatic and shelf depreciation in switchgear
With, and can prevent from occurring in switchgear condensation and lead to aggravate in switchgear harm caused by electrostatic and shelf depreciation.
