并聯(lián)低壓電容器主要特點(diǎn) main features
1. 體積小，重量輕
由于采用金屬化聚丙烯膜新材料作為介質(zhì)，體積、重量?jī)H為老產(chǎn)品的1/4 和1/5；
2. 損耗低
實(shí)際值低于0.1%，所以電容器自身的能耗低、發(fā)熱少、溫升低、工作壽命長(zhǎng)、節(jié)能效果佳;
3. 優(yōu)良的自愈性能
過電壓所造成介質(zhì)局部擊穿能迅速自愈，恢復(fù)正常工作，使可靠性大為提高；
4. 安全性
內(nèi)裝自放電電阻和保險(xiǎn)裝置，使用安全可靠；
5. 不漏油
本產(chǎn)品采用微晶蠟作為浸漬劑，常溫呈固態(tài)，熔點(diǎn)高于70℃，在使用過程中不漏油，避免環(huán)境污染。
1.Compacted and light
Its volume and weight are only 1/4 and 1/5 of the old product because of the using of new dielectric-metallized polypropylene film.
2.Low loss
The real figure is lower than 0.1%,so the capacitor itselfis extremely low the heat it gives out is little and the rise oftemperature is low.So its service.life is very long and it can save energy at the same time.
3.Excel lent self-healing ability
Damage of part of the dielectric caused by over-voltage can be self-healed quickly and return to normal state.So the reliability is much higher.
4.Safety
In wardly equipped self-discharge rseistor and safly equioment.
5.Nooil leakage
The capacitor uses advanced.Semi-solid impregnant whose drip melting point is above 70℃ ,There will be no loss of oil during the course of using it.And thus the surrounding is out from being polluted.The capacitor itself doesn’t have to run the risk of invalidation caused by oil leakage.
