产品详细资料
如果电源和配电设计不正确,可能会导致常见故障。因此,有必要:确定电源原理、具体接地原理、电源要求以及单独提供设备项目(例如系统内部电源和现场回路电源)的隔离要求。确保所选PSU与提供的电源馈线兼容。或者,应采取措施确保电源馈线保持在PSU的规格范围内。定义配电要求,以及每个配电的保护原理,例如源电流限制或保护装置。在使用保护装置的情况下,重要的是确定有足够的电流可用于确保其保护动作,并且保护装置可以断开大预期故障电流。确保电源足以满足系统负载以及任何可预见的负载要求和负载瞬变。确保电源的小输出保持时间为10ms。
The power supplies and power distribution, if incorrectly designed, present a potential common cause failure. It is therefore necessary to: Establish the power philosophy, specific earthing philosophy, power requirements, and the separation requirements where items of equipment are separately supplied, for example system internal supplies and field loop supplies. Ensure that the chosen PSUs are compatible with the power feeds provided. Alternatively, measures should be implemented to ensure that the power feeds remain within the specifications of the PSUs. Define the power distribution requirements, together with the protective philosophy for each distribution, for example current limited at source or protective devices. Where protective devices are used, it is important to establish that sufficient current be available to ensure their protective action and that the protective device can break the maximum prospective fault current. Ensure that the power supplies are sufficient for the system load and for any foreseeable load requirements and load transients. Ensure that the power supplies have a minimum output hold-up time of 10ms.
