Description
Technical field:
The present invention relates to lightning protection device structural design and applied technical field, a kind of back yard industry control room equipotential lightning protection servicing unit is provided especially.
Background technology:
In the prior art, people can carry out according to GB50057-94 " Code for design of lightning protection of buildings " and GB50343-2004 " building electronic information system shocking preventing technology standard " design and the application of lightning protection device in the building.Traditional lightning protection method is comprised of exterior protection and two links of internal Protection.Exterior protection is fire and the mechanical damage that occurs at building itself when preventing that thunder and lightning from hitting building.Comprise the outer facility of the thunder discharge electric current being led people's the earth of building: the ground network of lightning rod (lighting proof strip), downlead, Around Buildings and grounding system etc.But its technique effect is relatively limited.
Put it briefly, the lightning protection means of electronic equipment mainly adopt the methods such as shunting, ground connection and overvoltage protection.Wherein: 1, shunting: utilize lightning rod, lighting proof strip or lightning conduction etc. that lightning current is flowed into the earth safely along downlead, prevent that thunder and lightning from directly hitting on building and equipment.2, shielding: the plain conductor that computer system is all, comprise that power cable, telecommunication cable and holding wire all adopt shielding conductor or wear the metal tube shielding, in computer room construction, utilize building bar-mat reinforcement and other metal materials, make machine room form a screening cage.In order to prevent that external electromagnetic wave (containing electromagnetic wave and the electrostatic induction of thunder and lightning) from disturbing equipment in the machine room.
Therefore, people expect to obtain the good back yard industry control room of a kind of technique effect equipotential lightning protection servicing unit.
Summary of the invention:
The purpose of this invention is to provide the good back yard industry control room of a kind of technique effect equipotential lightning protection servicing unit.
The invention provides a kind of back yard industry control room with equipotential lightning protection servicing unit, with the coupling such as lightning protection device; It is characterized in that: it is specifically by the metal tape 1 that lays along wall and equipment enclosure 3 with consist of the metal grill 2 that is electrically connected with above-mentioned metal tape 1 and consist of, and reserves earth cable by cable and back yard industry control room and be connected; Described metal tape is specially the copper strips that transversal face length is 20-50mm, the wide 1.5-6mm of being; Described metal grill 2 specifically copper strips interconnection is arranged the equipotential grid that consists of, and metal grill 2 is parallelogram mesh, and its length of side is 300-2000mm;
The indoor normal not live metal conductor of Industry Control all by electric wire with above-mentioned metal tape 1 or/and metal grill 2 be connected.
Described metal tape is specially the copper strips that transversal face length is 25-40mm, the wide 2-4mm of being; Described metal grill 2 length of sides are 500-800mm.
Described back yard industry control room is with in the equipotential lightning protection device, and the equipotential lightning protection device adopts three grades of lightning protection hardware configurations:
First order lightning protection device: in uninterrupted power supply UPS input cabinet and power incoming line cabinet, lightning protection device is installed, is installed in parallel the outgoing line side in main circuit breaker;
