Preface
GB/T 27748 "Stationary Fuel Cell Power Generation System" is divided into the following 4 parts.
---Part 1.Safety;
---Part 2.Performance test methods;
---Part 3.Installation;
---Part 4.Performance test method of small fuel cell power generation system.
This part is Part 3 of GB/T 27748.
This section was drafted in accordance with the rules given in GB/T 1.1-2009.
This part replaces GB/T 27748.3-2011 "Stationary Fuel Cell Power Generation System Part 3.Installation". With GB/T 27748.3-
Compared with.2011, the main technical changes are as follows.
--- Increase the scope of application of the standard to avoid overlap between IEC 62282-3-100 and IEC 62282-3-300 in terms of safety-related provisions;
---Update reference documents and definitions;
--- Delete the requirements for stationary fuel cell power generation systems, so that the target of this standard is focused on "installation risk";
---Simplify the requirements of CO level for the situation where small fuel cell power generation system directly emits exhaust gas into the installed and reliable and safe simple shed;
---Modify the requirements for the use of combustible gas detection systems;
---Increase the reference to the gas valve standard ISO 23551-1.
The translation method used in this section is equivalent to IEC 62282-3-300.2012 "Fuel Cell Technology Part 3-300.Stationary Fuel Cell Power Generation System Installation".
The Chinese documents that have consistent correspondence with the international documents cited in this section are as follows.
---GB 3836.14-2014 Explosive atmosphere Part 14.Site classification Explosive gas atmosphere (IEC 60079-10-1.2008, IDT)
---GB/T 5464-2010 Non-combustibility test method of building materials (ISO 1182.2002, IDT)
---GB/T 16856-2015 Machinery Safety Risk Assessment Implementation Guidelines and Examples of Methods (ISO /T R14121-2.2012, MOD)

Part 3.installation
1 Scope
This part of GB/T 27748 specifies the minimum safety requirements for stationary fuel cell power generation systems installed indoors and outdoors.
The national standard GB/T 27748.1-2017 is applicable to the installation of the following systems.
It is expected to be electrically connected to the main equipment directly or through easy-to-operate (fast) manual switches and circuit breakers;
Anticipated independent power distribution system;
Expect to provide alternating current or direct current;
With or without recovery of available heat capacity.
This standard only applies to equipment and property that may cause personal injury or cause fuel cell power generation system equipment during the installation process.
The situation of damage.
The safety of stationary fuel cell power generation systems involved in GB/T 27748.1-2017 is not included in this standard.
Moreover, this standard does not include.
--- Fuel supply and/or fuel storage system;
---Supply and treatment of auxiliary media;
---Switch or circuit breaker;
---Portable fuel cell power generation system;
---Driven fuel cell power generation system;
---Auxiliary Power Generation System (APU).
