There are a series of elements and materials, as in the case of LV equipment, for its HV operation that must accompany our HV capacitors for their correct operation and for that of our installation/network, as well as the rest of the equipment that compose it and that are in parallel operation with the capacitors that we want to put into service for the correction of the power factor (compensation of the consumption of Reactive Energy).
在一些低压的设备中有一系列的元件和材料，其高压操作必须配合我们的高压电容器，以便其正确操作，并组成了我们的安装/系统，同理，组成系统的其他设备也与我们要投入使用的电容器用于功率因数的校正（无功能量消耗的补偿）。
The choice of one type of equipment or another, as well as its configuration, will depend not only on the final cost of the equipment, but will also be marked by the mains voltage, as well as the loading regime of our installation.
选择一种或另一种设备，以及它的配置，不仅取决于设备的最终成本，而且也取决于电源电压以及安装的加载方式。
There are two types of banks, depending upon the mode of connection. First is 3 phase single star connected, which is suitable, where voltage is preferably low, say up to 6,6 kV. Other is 3 phase double star connected bank assembled with minimum 6 Nos of single phase units, preferably for systems where voltage is higher, say 11 kV and above.
有两种类型的组柜可供选择，这取决于连接方式。一种是三相单极连接，适合于低电压，例如6.6kV。另一种是三相双极连接组，有最少6个单极组成，适用于电压较高的系统，例如11kV及以上。
Direct three-phase connection.
直接三相连接。
They are formed by the connection of 1 to 4 three-phase capacitors in parallel. The internal connection of the three-phase capacitor of all the “elements” of which it is composed is in the form of a star.
它们是由1至4个三相电容器并联连接而成的。三相电容器的内部连接是由一个星型结构构成的。
The batteries may consist of the following components (depending on the characteristics of the installation):
电池可以由以下部件组成（取决于安装的特性）：
- Metal enclosure. 金属外壳
- APR protection fuses APR保护熔断器.
- Switching contactor (opt.).切换接触器（可选）
- Shock ballasts. 冲击镇流器
- Capacitors. 电容器
Logically, the existence of these elements depends on the client’s need and the network topology.
逻辑上讲，这些元件的存在取决于客户的需求和网络拓扑结构。
Generally speaking, the use of this type of battery is limited to insulation levels of 12 kV and powers from 50 to 1600 kvar / 2400 kvar, depending on the operating voltage if it is 6.6 kV or 11 kV.
一般来说，这种架构的使用仅限于12kV的绝缘水平和50至1600kvar/2400kvar的功率，这取决于工作电压是6.6kV还11kV。
Three-phase connection through a double star.
通过双极三相连接
Formed by single-phase capacitors configured in two stars joined by a common neutral. The purpose of this connection is the possibility of incorporating an unbalance protection for the detection of possible internal defects in the capacitors due to the wear and tear and ageing of the equipment or defects that may occur from the electrical network.
由两个星型结构的单相电容器构成，由一个共同的中性线连接。这种连接的目的是将不平衡保护引入到电容器内可能的内部缺陷的检测中，这是由于设备的磨损和老化以及可能发生的电网络缺陷引起的。
Combined with capacitors with internal fuses, not only high safety, but also greater service continuity is achieved.带有内部熔断器的电容器，不仅安全性高，而且还具有更好的服务连续性。
The number of capacitors in the double star depends on the mains voltage and the required battery power. In any case it must always be a multiple number of 3 and never less than 6 units.
双星结构中的电容器的数量取决于电源电压和所需的柜组功率。在任何情况下，它必须始终是3的倍数并且不能少于6个单位。
The batteries may consist of the following components, depending on the characteristics of the installation:
电池可以由以下部件组成（取决于安装的特性）：
- Metal enclosure.金属外壳
- Gen. switch Automatic in SF6 of maneuvering (opt).
在SF6的演习中中自动切换（可选件） - Shock ballasts.冲击镇流器
- Unbalance current transformer.不平衡电流互感器
- Capacitors.电容器
- Unbalance relay (optional).不平衡继电器（可选件）
Normally used when the configuration up to 12 kV max. voltage is not feasible due to power level (high power of Reactive Energy demanded) or insulation level (insulation voltages higher than 12 kV due to mains voltages of secondary transformers higher than 11 kV).
通常适用于当由于功率水平(要求高无功功率)或绝缘水平(由于次级变压器的主电压高于11kV，绝缘电压高于12kV)而配置到12kV最大电压不可行时。
