產(chǎn)品概述 Product description
IVD電容器設(shè)計(jì)用于低壓網(wǎng)絡(luò)中的功率因數(shù)校正（PFC）。它們可用于：
-電機(jī)，變壓器等的單獨(dú)固定PFC
-自動(dòng)PFC設(shè)備
-調(diào)諧和失諧的電容器組
IVD-C電容器具有三個(gè)獨(dú)立的金屬化聚丙烯膜繞組，分別位于圓柱鋁罐中。內(nèi)部以星形或三角形連接。使用三個(gè)獨(dú)立的堆疊繞組可確保低損耗，具備優(yōu)異的浪涌電流性能以及繞組的良好散熱。繞組的高真空干燥可以在恒定電容的情況下延長(zhǎng)使用壽命。
由于開(kāi)關(guān)操作，在低壓電網(wǎng)中可能會(huì)出現(xiàn)不超過(guò)額定電壓3倍的電壓峰值。如果這些應(yīng)力引起電介質(zhì)擊穿，則自愈機(jī)制將發(fā)揮作用。自愈后，電容器繼續(xù)正常工作。電容容量衰減可以忽略不計(jì)。
IVD電容器配有拉斷保護(hù)。當(dāng)故障點(diǎn)反復(fù)自我修復(fù)或任何其他內(nèi)部故障導(dǎo)致的內(nèi)部壓力上升達(dá)到額定值時(shí)，拉斷保護(hù)動(dòng)作。在這種情況下，鋁蓋可能會(huì)鼓出，并且電容器會(huì)在軸向上膨脹。膨脹導(dǎo)致內(nèi)部連接線斷開(kāi)，電容器從電力系統(tǒng)安全地?cái)嚅_(kāi)。
電容器內(nèi)置放電電阻，保證電容器電壓在3分鐘內(nèi)放電至36V或以下。
Application
IVD capacitors are designed for power factor correction (PFC) in low voltage networks. They may be used for:
- Individual fixed PFC of motors, transformers, etc.
- Automatic PFC equipment
- Tuned and detuned capacitor banks
Construction
The IVD capacitors have three separate windings from metalized polypropylene film placed in a cylindrical aluminium can. The partial capacitances may be connected either in star or delta configuration. The use of three separate stacked windings guarantees low losses, optimal surge current performance and good heat drain from the windings. A high-vacuum drying of the windings gives long service life with constant capacitance.
The terminal is designed as a double 3-pole terminal block (IP 20).It is possible to clamp multiple-wires with a cross section up to 35 mm2 ．
Due to switching operations, inadmissible voltage peaks of up to 3 times that of the rated voltage can occur in low voltage networks. If these stresses affect a dielectric breakdown, the self-healing mechanism will function. After self-healing, the capacitor continues its complete operation. The decrease in capacitance is negligible.
IVD capacitors are equipped with an overpressure expansion fuse. The fuse operates when the internal pressure rise affected by repeated self-healings on faulty spots or any other internal failure has reached a determined value. In this case the lid of the aluminium can bulge out and the capacitor expands in the axial direction. Due to this expansion the planned fracture in the internal connecting wires break and the power capacitor is disconnected safely from power supply system.
Power capacitors must be discharged in 3 minutes to 36V or less. No switch, fuse or any other isolating device should be between the power capacitor and the discharge device. Power capacitors which are directly connected to other electrical equipment providing a discharge path can be considered as properly discharged, provided that the circuit characteristics ensure the discharge of the power capacitor within the time specified above. IVD capacitors will be delivered with discharge resistors.
