1 Usage and the scope of application 1.1 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 ways ●The 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 0675 ● American standard: UL 1449 ● UK 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 connected ● New 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 maintenance ●The 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 conditions |
