BY6 series Surge Protective Devices

Usage and application scope of BY10 type surge protective device (short name "SPD") is suitable for AC 50/60 Hz,380V 1.  Usage and the scope of application1.1 BY6 surge protective device (hereinafter referred to as “SPD” ) be suitable for AC 50/60 Hz , 380/440V and the following electric power systems ;Also can be used to 50/60 Hz,DC110V and following electric power systems, to protect the electric network from lightning or other impulsing.    SPD accord with GB 18802.1—2002(equal to IEC 61643-1:1998). The series products will be protected by six patents (including invention ,practical new style and external aspect etc.)We can make products as following standards according to customer request.Ministry of Public Security standard: GA 173-2002 computer information system lightning protector Meteorology standard: QX 10.1—2002 Surge Protective Device Part one: performance requirements and experiment waysThe ministry of information standard: YD/T 1235.1—2002 communication bureau low voltage electric system SPD technical requirements France standard : NFC 61740 Germany standard: VDE 0675American standard: UL 1449UK standard: BS 6651 BY6 series are new developing items which based on BY4 and BY1, various improvements as following: Product external aspect and installation dimension comply with modular electrical standard, easy to match with end devices.Adopt Kelvin terminal, which easily be connectedNew style overheat disconnected protection device :for the multi-piece products, adopt overheat separately disconnected, indication and with all modules failure remote control alarm system. This disconnection device be used for multi-piece products, when one( or several) piece of among these MOV failure will send out error signal meanwhile the remains MOV still normal work .Of course , all MOV of one module be failure will send out alarm signal through output contactor ,then promote product performance (already got the patent) .Inside of module ,as shorten connection line as possible then increased resistant impulse current efficiently ,reduced residual voltage.Base unit conductive connection, adopt elastic structure then increasing contact reliability and reducing power of draw or insertion. It is very convenient for maintenanceThe module to match with base unit ,which be adopted 4 sets limited conditions, then it can realize 24 ways to match ,to avoid wrong inserting module when customer maintenance(already got patent).BY6 series with many various kinds of types for customer to choose .1.2  SPD normal working conditions1.2.1  Altitude can not beyond 4000m;1.2.2  Temperature of surrounding environment :normal scope:-5~+40º,extend scope: -40~+70º1.2.3 Relative humidity of atmosphere: indoor temperature conditions 30%~90%1.2.4 No marked wave and vibration1.2.5 No explosion and dangerous medium, the medium content of gas and dust can not beyond degree that erode metal or destroy insulation(including conductive dust).2.1 Type and indicate meaningBY6accessories:X -output contactorB -alarm    J -lightning counternormal discharge current In(kA)Maxi continuous working voltage (V~)combined method(see sheet 2)Maxi discharge current  Imax(kA)design No.surge protective device2.2   Specifications:2.2.1          According to current classification:Imax   15 ,25 ,40 ,60 ,80,100,120,150 kAIn       5 ,10 ,20 ,30, 40,50, 60 ,70kA2.2.2          According to maxi continuous working voltage Uc:65,180V-,150,300,345,385 V~2.2.3          According to poles:1,2,3,42.2.4          According to subsidiary functions:output contactor, alarm, lightning counter2.2.5   According to protection mode: connect to the ground with same line, L1,L2,L3..-N-PE,  “2+1”,  “3+1”2.2.6          Detailed specifications (see table 1)2.3     Base unit composite type(see table 2)2.4     Basic parameter·Maxi continuous working voltage    Uc   65,180V-,150,300,345,385 V~·Test by classified                    II ·Protection level                   UP  0.5,0.8 ,1.5 ,1.8,2.0 ,2.2,2.5kV·Maxi discharge current(8/20µs)     Imax  15 ,25 ,40 ,60 ,80,100,120,150 kA·Normal discharge current  (8/20µs)      In      5 ,10 ,20 ,30,40, 50, 60,70 kA
