普通電容和安規(guī)電容有哪些不同之處
作者:紅寶電容 來源:http://www.whweier.com 日期:2020-07-30 09:40 瀏覽 次

  一些電容表面、形狀等看起來差不多,但其本質(zhì)是完全不同的。就拿安規(guī)電容和普通電容舉例說明,安規(guī)電容與普通電容有什么區(qū)別。

  The surface and shape of some capacitors look similar, but their essence is completely different. Take the safety capacitance and ordinary capacitance as examples to illustrate the difference between safety capacitance and ordinary capacitance.

電容的區(qū)別.jpg

  1.應(yīng)用范圍不同

  Different applications

  安規(guī)電容主要為為X電容和Y電容。

  The safety capacitance is mainly x capacitance and Y capacitance.

  X電容為抑制差模干擾,一般跨接與L與N之間(N代表零線,L代表火線),常見的是X1電容和X2電容。每個(gè)等級的耐壓不同。失效時(shí)不會(huì)對人體產(chǎn)生危害。

  In order to suppress the differential mode interference, X capacitor is usually bridged between L and n (n represents the zero line, l represents the live wire), and the common ones are X1 capacitor and X2 capacitor. The withstand voltage of each grade is different. Failure will not cause harm to human body.

  安規(guī)Y電容又分為Y1電容和Y2電容,為抑制共模干擾,Y電容是安規(guī)系列的電容,在火線和地線之間以及零線和地線之間并接的電容統(tǒng)稱Y電容。一般會(huì)有漏電流。

  Safety y-capacitor is divided into Y1 capacitor and Y2 capacitor. In order to suppress common mode interference, y-capacitor is the capacitance of safety regulation series. The capacitance connected in parallel between live wire and ground wire and between neutral line and ground wire is collectively referred to as y capacitance. There will be leakage current.

  安規(guī)電容主要適用于電源供電的電子儀器和電子設(shè)備,應(yīng)用于開關(guān)、觸點(diǎn)等產(chǎn)生火花放電的部位,能夠起吸收脈沖干擾和減少電磁騷擾的作用。

  Safety capacitor is mainly used for power supply of electronic instruments and electronic equipment, applied to switches, contacts and other parts of spark discharge, can absorb pulse interference and reduce electromagnetic interference.

  普通電容器廣泛應(yīng)用于各類電子設(shè)備、微分電機(jī)、電動(dòng)工具、照明燈具、空調(diào)器、電冰箱、洗衣機(jī)等家用電器以及電力系統(tǒng)中。

  Ordinary capacitors are widely used in all kinds of electronic equipment, differential motors, power tools, lighting lamps, air conditioners, refrigerators, washing machines and other household appliances and power systems.

  2.外觀不同。

  Different appearance.

  像X類安規(guī)電容,一般都安裝在塑膠外殼內(nèi),普通的CBB電容,多數(shù)都是環(huán)氧樹脂包封。

  For example, class X safety capacitors are generally installed in plastic cases. For ordinary CBB capacitors, most of them are encapsulated in epoxy resin.

  3.認(rèn)證不同。

  Certification is different.

  普通的CBB類電容,它不需要過任何認(rèn)證,但安規(guī)電容一般要過很多認(rèn)證,比如CQC、VDE、 UL、CUL等,而且過的認(rèn)證越多越好。

  Ordinary CBB capacitors do not need any certification, but safety capacitors generally have to pass a lot of certification, such as CQC, VDE, UL, cul, etc., and the more certification, the better.

  4.價(jià)格不同。

  Different prices.

  同容量、同電壓,安規(guī)電容相對要貴一些,因?yàn)檫@些電容每年要花大量的認(rèn)證費(fèi)用,而且制作工藝也不同。

  With the same capacity and voltage, safety capacitors are relatively expensive, because these capacitors have to spend a lot of certification fees every year, and the manufacturing process is also different.

  所以說,不同型號的電容有著不同的功能,只要我們根據(jù)使用需求選擇適合的電容即可。

  Therefore, different types of capacitors have different functions, as long as we choose the appropriate capacitor according to the use needs.
