  1. 1. 177 Installation Diagram Building lightningproof regional map Classification of lightningproof zone for buildings (LPZ) Primary protection for power supply (MBD1-B) Primary protection for signal circuit (MBX-RJ45) (ALT) Protector for CATV circuit (MBD-T) Secondary protection for power supply (MBD1-C) Secondary protection for signal circuit (MBX-RJ45) Protector for antenna feeder In order to distinguish the degree that lightning electromagnetic pulse(LEMP) on different lightningproof zone and the position of equal potential inthe joint between differentzones. The protected zone divided into several lightningproof zones (LPZ). LPZ0A zone:all objects in this zone may be strikeby direct lightning and carry full lightning current, electromagnetic field strength has no attenuation. LPZ0B zone: withi n the relevant scopeof selected grounder radius in this lightning-proof zone, the objects may not be strike by direct lightning, but electromagnetic field strength has no attenuation. LPZ1 zone: the objects in thiszone are impossibly strike by lighting, lighting current on conductors and electromagnetic field strength are attenuated, the attenuation degree is determined by field solutions in the buildings. LPZ2 zone: if required to further reduce lighting current and electromagnetic field strength, it shall add extra lightningproof zone, such as machine room with shield, metal shellof equipment, machine cabinet and etc; it shall determine suchzone according to ambient conditions for the protected object.

TT power supply network: TT mode is namely the protection system that metal shell of electric consumer directly earthed, calling protective earthing system, or TT system. 2. TN power supply network: this system require metal shell of electric equipment is connected with neutral line, also calling Neutral protection system, indicated by TN. 3. TN-C power supply network: neutral line also used as protective ea rthing wire, calling Neutral Protective earthi ng line, indicated by NPE. 4. TN-S power supply network: neutral line (N) and protective earthing (PE) wire are separated. 5. TN-C-S power supply network: in the temporary power supply for the constructing sit e, if front supply ne twork is TN-C, and TN-S network shall be required on local constructing sites, so PE line can be divided from general distribution box on local site. 6. IT network, I means isolation without earthing, or earthing via high resistance. Every two letters of 'T' means electric consumer of loading side is protective earthed.

MBD1-R series protector has integrated short circuit protective function in its SPD module, fuse notneeded again, itcan be mountedon35mm railway, compared with normal combination of fuse+ SPD module, there has following advantages: Residual voltage reduce morethan 50%, for normal combination, fuse bodyandconnected conductor haveinductance,and willresult in residual voltage, but MBD1-R series almos t has noresidualvoltage at this case, therefore it can getbetter result ofprotecting equipment. Easy installation, saving space, saving installation cost in cabinet. Quicker response speed,comprehensive performance being improved. Better N point:no matter which step of circuit, there has shortestdistance for discharging surge current,residualvoltage decrease more.

If cooperated with MBD1-C40 series surge protec tive device, it is constructed as 1P+1NPE; 2P+NPE, 3P+NPE combined SPD, this is to improve the surging protective performance. As per the conditions of IEC61643-1:1998-02 standard, Class II surgeprotective device, it is category C surge protective device. N-PE meets withGB18802.1/IEC61643-1 standards. Operation Elements The main operating element of NPE is gas discharging tube or air discharging gap, ge- nerally, it is high resistance between electr- odes, while the surge of direct and indirect lightning impulse and other transient over voltage influence on the power network, the SPD between electrodes will be conductive within short time (ns), and leading surging current into ground, consequently to protect the electric appliances of network. After surging voltage passed by NPE, and disa- ppeared, NPE recovers in high resistance. It will not have influence on the normal service of network. Installation NPE and MBD1-C series surge protective devices forms MBD1-40-1P+N, 2PN, 3+P+N and etcSPD, with MC and MD protection modes.

MBD-Z-300 Operation Elements Non-electronic type, long working life, only when lightning happen, the lighting rod will beexcitedby itself, withprospective disch-arging function, forwardly guide the lightning system, after to withstand repeated lightning discharging, it still has such continuity ofelectric performances. NB: The above data is calculated on basis of lightning rod height H = 5m. Calculation formula of protective radius at prospective self-discharging If prospective discharging time: T, then prior lead-up distance L=V* T, according to calculation methods specified in NFC-17-102 standard, protective radius Rp come from the following formula: Representative= h(2D-H)+ L(2D+ L) h 5 D distance of lightning strike, determined by the grade of objects to be protected, for category III object, D equal to 20m, 45m, 60m respectively.

  26. 26. Surge Protective Device The appliance used to limit transient over voltage and dis charge the surging current, it includes one of non-linear element at least. Impulse Current It determined by current peak value and electric charge Q, it shall be performed according tothe program for test of acting load. It is used for SPD classification of Class I test. Maximum Discharge Current Forclass Test Passing through SPD, the peak value of current with 8/20 wave, determined by the program for Class II acting load. Imax larger than In. Maximum Continuous Operating Voltage Maximum AC virtual voltage or DC voltage allowed to be applied on SPD continuously, the value equal to rated voltage. Voltage Protection Level It indicates the performance of SPD limiting the voltage between terminals being connected. The value can be selected from the sheet of prior values. This val ue shall be larger than highest limited voltage. Explanation Of SPD Technical Term Voltage Switching Type SPD SPD that it shows high impedance when there has no surging, and becomes low impedance while surging voltage occurs. Voltage switching type SPD generally composed of discharging gap, gas discharging tube, thyratron (silicone controllable rectifier) and three-ending bidirectional silicone switching element. Sometimes it also call "short circuit type SPD" . Voltage Limiting Type SPD SPD that it shows high impedance when there has no surging, but the impedance will decrease gradually while surging current and voltage rise up. Common non-linear element: piezoresistance, and clamping diode. Sometimes it also call "Clamping SPD". Combination SPD SPD constructed of voltage switching and voltage limiting elements. The characteristics curve can take on the characteristics of voltage switching or limiting type, or both. Modes Of Protection Protective element of SPD can be connected between phase line to phase line (L-L), phaseline to earth (L-PE), phase line to neutral line (L-N), neutral line to earthing line (N-PE) or their combination. These connections call protection modes. SPD Disconnector The device that isolates SPD from power supply network (interior and / or outer). Nominal Discharge Current The 8/20 wavecurrent peak that passing by SPD, used for grading SPD under class II test, or prospective treatment of SPD class I, II test. 202
