产品详细资料
Tricon控制器的金属板连接到安全接地。Tricon控制器通常通过电阻电容（RC）网络将安全接地连接到信号接地。该网络可以断开以允许替代接地实现或浮动接地应用。作为浮动系统的一部分安装Tricon控制器时的指南实现零电压接地参考在接地母线上实现零电压的接地参考对于正确的系统接地至关重要。此图列出了Tricon系统接地网或其他可接受接地点的值。图95:1中的注释。绝缘电线，尺寸符合当地规范。2.当使用专用系统接地时，以及当需要与工厂公用设施接地进行电流连接时，该连接必须具有大于或等于20微亨的电感，并具有低杂散电容。为此，可以使用合适的高频扼流圈或小6 AWG（16平方毫米）的绝缘导体，长度为60英尺（20米）。3.Tricon设备的每个单独衍生电源必须返回到单个接地点，例如接地网或其他可接受的接地。以下接地电阻值必须遵守并保持符合IEEE标准142：•对于发电厂应用，接地电阻必须等于或小于1欧姆。•对于工业设备，接地电阻必须小于或等于5欧姆。
The sheet metal of the Tricon controller is connected to the safety ground. The Tricon controller is normally delivered with the safety ground connected to the signal ground by means of a resistor-capacitor (RC) network. This network can be disconnected to allow for alternative grounding implementations or floating ground applications. For guidelines when installing a Tricon controller as part of a floating system Achieving a Zero-Voltage Ground Reference Achieving a zero-voltage ground reference at the earth bus is essential to proper system grounding. This figure lists the values for a ground grid or other acceptable ground points for a Tricon system.Notes on Figure 95: 1. Insulated wire, size per local code. 2. When using a dedicated system ground, and when galvanic connection to plant utility ground is required, this connection must have an inductance greater than or equal to 20 microhenries, with low stray capacitance. A suitable high frequency choke, or an insulated conductor of 6 AWG (16 square millimeters) minimum, with a length of 60 feet (20 meters), may be used for this purpose. 3. Each separately derived power source for Tricon equipment must return to a single grounding point, such as the ground grid or other acceptable ground. The following ground resistance values must be adhered to and maintained per IEEE Standard 142: • For power plant applications, ground resistance must be equal to or less than 1 ohm. • For industrial plants, ground resistance must be less than or equal to 5 ohms.
