自动电气控制.第2-15部分:自动电气空气流量、水流和水位传感控制的特殊要求

[中文适用范围]： 本部分IEC 60730适用于最大压力额定值为2000 kPA（20 bar）的锅炉以及与一般家用和类似用途设备（包括加热、空调和类似应用的设备）相关的自动电气气流、水流和水位感应控制。 本文档还适用于公众可能使用的自动电气气流、水流和水位感应控制设备，如用于商店、办公室、医院、农场以及商业和工业应用的设备。 本文档适用于自动电气气流、水流和水位感应控制的固有安全性、操作值、与设备保护相关的操作序列以及测试。 本文档不适用于压力感应控制，其要求包含在IEC 60730-2-61中。 本文档不适用于专门为工业应用设计的气流、水流和水位感应控制，除非相关设备标准中明确提到。 本文档适用于额定电压不超过690 V交流或600 V直流的自动电气气流、水流和水位感应控制。 [外文原描述]： IEC 60730-2-15:2017 applies to automatic electrical air flow, water flow and water level sensing controls for use in, or in association with, boilers with a maximum pressure rating of 2 000 kPA (20 bar) and equipment for general household and similar use including controls for heating, air-conditioning and similar applications. Examples are water flow and water level sensing controls of the float or electrode-sensor type used in boiler applications and air flow, water flow and water level sensing controls for swimming pool pumps, water tank pumps, cooling towers, dishwashers, washing machines, air conditioning chillers and ventilation applications. This document also applies to automatic electrical air flow, water flow and water level sensing controls for equipment that may be used by the public, such as equipment intended to be used in shops, offices, hospitals, farms and commercial and industrial applications. This third edition cancels and replaces the second edition published in 2008. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition: changes to align with the fifth edition of 60730-1, including the revised title. This Part 2-15 is intended to be used in conjunction with IEC 60730 1. It was established on the basis of the fifth edition of that standard (2013). Consideration may be given to future editions of, or amendments to, IEC 60730-1. This Part 2-15 supplements or modifies the corresponding clauses in IEC 60730-1, so as to convert that publication into the IEC standard: Particular requirements for humidity sensing controls. Where this Part 2-15 states "addition", "modification" or "replacement", the relevant requirement, test specification or explanatory matter in Part 1 should be adapted accordingly. Where no change is necessary, this document indicates that the relevant clause or subclause of Part 1 applies.
