Description of drawings
By being carried out various performance detection, product of the present invention further specifies feature of the present invention more below:
The cleaning temperature that subordinate list 2 is used for the electrification in high voltage sanitising agent of 500KV electric apparatus equipment changes and cleaning effect;
The variation of subordinate list 3 cleaning object insulation values:
Subordinate list 4 certain F7 of Municipal Telecommunication Bureau switch cabinet contact clean test chart.
Embodiment
Can see that from the detected result of table 1, table 2 and table 3 electrification in high voltage sanitising agent involved in the present invention has following novelty:
(1) do not contain the Ozone Depleting Substances (ODS) that international convention is forbidden;
(2) life-span in the atmosphere convection layer is lower than 10 years, and ozone depletion latent energy value (ODP) is not more than 0.03, and global warming potential (GWP) is not more than 0.1.
(3) have no flash-point, incombustible advantage;
When (4) under up to the operating voltage of 500KV high voltage electric power equip ment being carried out charged cleaning is safe;
(5) ice-crystal effect can not appear when high voltage electric power equip ment is carried out charged cleaning;
(6) the condensation phenomenon can not appear when high voltage electric power equip ment is carried out charged cleaning;
(7) when high voltage electric power equip ment is carried out charged cleaning, the surface insulation value of equipment can obviously not descend;
(8) can corrosion-damaged equipment;
(9) wash degree height, cleaning performance is good.
Test chart when using sanitising agent involved in the present invention certain F7 of Municipal Telecommunication Bureau number oily machine direct-furnish cabinet turnover wiretap contact being cleaned sees Table 4 and contact load variations Fig. 1.
From table 4 and Fig. 1 as can be seen, the contact resistance after the cleaning has obviously descended, and has played the effect that weakens electric arc, prolongs the contact life-span.
