I. Industry Overview
Cultural heritage buildings are basically built on the back, or on the water, or on relatively flat terrain. The wooden structures used are basically wooden structures. In order to allow people who come to travel to have a better experience, the ancient architecture also carried out two Sub-decoration, the addition of lighting and related monitoring of the circuit, etc., brought a relatively large hidden dangers to ancient buildings: easily damaged by lightning strikes ancient buildings and lightning strikes caused the burning of ancient buildings.
Second, the design requirements
In the lightning protection design and construction, due to the different shapes and unique structures of ancient buildings, they must be carried out according to their characteristics, so that the installed lightning protection facilities must be both safe and beautiful and must be concealed and reliable. Buildings get the most beautiful and most reliable security.
According to GB50057-2010 Standard for Design of Buildings for Lightning Protection, ancient buildings should be designed for Class II lightning protection.
Third, design lightning protection products
1. Use DXH06-FLB/2R25 (single-phase) or DXH06-FLB/4R25 (three-phase) as the primary protection of the power supply. Use DXH06-FCS/2R40 (single-phase) or DXH06-FCS/4R40 (three-phase) as The second level of power protection, the use of DXH06-Z10/5K as a third-level lightning power outlet.
2, according to GB50343-2012 "building electronic information systems lightning protection design specifications," the first 6.5.1 table, the first level of protection SPD connection phase with 10mm2 stranded copper wire, ground with 16mm2 stranded copper wire. The second stage protects the SPD connection phase with 6mm2 stranded copper wire and the ground wire with 10mm2 stranded copper wire.
3. If the weak current and network system are protected at the same time, install the network SPD of the QFL06-MG in front of the switch; install the signal SPD of the QFL06-MA before the program-controlled telephone bus in the office; if there is a monitoring system, it shall be equipped with the QFL06-MV series or DXH06-AVC three-in-one monitor lightning arrester.
