introduction
In recent years, there have been more and more economic disputes caused by fires and explosions in computer rooms and data centers, which have also brought adverse social impacts.
It is necessary to standardize the installation safety regulations and form standards. Telecommunication base stations in America, Europe and other countries are installed in accordance with IEC 62485-2.2010.
The installation demand of Chinese companies and operators is greater than that of foreign countries, but there has been no safety standard for installation in China.
The workers operate according to their own experience, which poses a great safety hazard. The only current domestic standard is NB/T 42083-2016 "Power System
"Technical Specifications for Safe Operation and Use of Fixed Lead-acid Batteries", which only provides relevant safety specifications for lead-acid batteries and is only applicable to electric
Factory, the scope of use is limited, and other types of fixed batteries are not included.
GB/T 44233 "Safety requirements for installation of batteries and batteries" is planned to consist of 6 parts.
--Part 1.General safety principles. The purpose is to specify the safety precautions that need to be taken when batteries and batteries encounter problems during installation and operation.
Protective measures taken.
-- Part 2.Stationary batteries. The purpose is to specify the safety requirements for the installation of stationary batteries.
-- Part 3.Traction batteries. The purpose is to specify the safety requirements for the installation of traction batteries.
--Part 4.Lead-acid batteries for portable applications. The purpose is to specify the safety of the installation of lead-acid batteries for portable applications.
Require.
-- Part 5.Safe operation of stationary lithium-ion batteries. The purpose is to specify the safety of stationary lithium-ion batteries.
Require.
-- Part 6.Safe operation of lithium-ion batteries for traction. The purpose is to specify the safe operation of lithium-ion batteries for traction.
Require.
The purpose of this document is to provide a standardized installation for stationary batteries by specifying the safety requirements for the installation of batteries and batteries.
and detection methods to prevent the operator from being harmed by dangers such as battery charging and discharging, explosive gas, short circuit, swelling, electrolyte leakage, etc.
And the main protective measures taken when a safety accident occurs.
