In order to guarantee that this energy-storage system is safe and reliable, prevent from leading to the damage of system device because of external factors such as lightning stroke, surges
Bad situations such as, occurs, ground connection copper billet of the lower angular region installation of the cabinet 10 4 to prevent lightning stroke.The lightning protection structure of cabinet 10
Design:
10 pad nand function electric conductor (uncharged metal shell under normal circumstances) of cabinet is reliably connected, together
When, 2 reliable ground points (reserved copper bar, sectional area are not less than 100mm2) is provided, grounding point is diagonally arranged.Case top is by connecing
Ground band steel or round steel connection cabinet 10 are reserved on grounding copper bar, and the effective sectional area of conductor is not less than 90mm2 in earthed system.It is interior
Portion's equipment shell uniformly passes through grounding copper bar (sectional area is not less than 75mm2) and connects into concentration ground connection system with 10 grounding point of cabinet
System when the concentration earthed system disconnects, meets the requirement for reinforcing insulation between 10 system of equipment shell system and cabinet.Bottom
Non- inlet-outlet line region is laid with insulation voltage and is not less than 3kV, and insulation thickness is not less than the high quality fire retardant insulating pad of 4mm.It uses simultaneously
Family can rationally design communication lightning-protection distribution, earthing or grounding means and lightning protection measures according to whole system situation.
The grounding-for-lightning device measure of system mainly takes following measures there are many method: (1) ground wire be take shelter from the thunder, lightning protection
Key, carrying out 10 infrastructure of cabinet and while current transformer container infrastructure, select equipment nearby thicker soil,
Moist place digs 1~2 meter of deep ground wire hole and adds friction reducer using 40 band steels and draw ground wire, lead-out wire uses 10mm2 copper
Core cable, ground resistance should be less than 4 ohm；(2) lightning rod is built near case, it is 15 meters high, and a ground wire is individually made, method is same
On, switchgear house does not need lightning rod in basement；(3) DC side lightning protection measures: cabinet 10 should ensure that good ground connection, can be effective
Ground, which avoids being struck by lightning, leads to the damage of equipment；(4) cabinet has good contact with ground.
The foregoing is merely illustrative of the preferred embodiments of the present invention, is not intended to limit the invention, all in essence of the invention
Made any modifications, equivalent replacements, and improvements etc., should all be included in the protection scope of the present invention within mind and principle.
