翻译:用在电器上的塑胶材料的要求翻译:◆介绍:涉及标准塑胶材料的类型◆选择基本标准:电器特性可燃性特性温度特性◆应用塑胶外壳带电部分的直接支撑物的材料◆概要翻译:UL标准UL746C—使用在电器设备上的塑胶材料的评估。

笔记:主要为如何根据黄卡上的信息选择材料材料类型:热塑性塑胶热固性人造橡胶(弹性体)翻译: 电气特性:抗灼热丝点燃(HWI ):点燃缠绕着电阻丝的样品的平均秒数,其中电阻丝通以规定等级的电流。

等级分为:0、1、2、3、4、5笔记:把发热丝包在材料的外表面,通电,看材料燃烧时间的长短,如在7S 内燃烧就为第5个等级。

样品消耗功率:0.26W/mm翻译: 电气特性:抗电弧点燃(HAI ):当以标准的速度在材料表面施加电弧,点燃材料的电弧数量。

笔记:两个高压电极之间按一定的频率产生电弧,看多少个电弧能使材料燃烧,共分为0、1、2、3、4个等级固定电极可移动电极 条形样板翻译:电气特性:相对漏电起痕指数(CTI):用于评估材料暴露在不同污染环境下的漏电可能导致的火灾或电击危害。

笔记:CTI:材料抗污染的程度,材料表面一段时间后会堆积一定的污染物,在材料的两端连接两个电极,看污染到多少程度会使材料表面两个电极相通。

分为0、1、2、3、4、5个等级CTI数字与厚度没有关系翻译:在塑胶材料库中的HWI、HAI、CTI(+)――原始材料和不超过50%的重量内含物的碾磨材料的混合,具有同样的基本材料特性。

(f1)――适于户外使用,并根据UL746C,暴露在紫外线下,水源和浸入水中的材料。

注意――1)色粉的材料名称要有后缀的字母和数字。

2)材料名称前面可以有“ZYT”,“MIN”,“ZEN”“DEL”“CRA”“RYN”这些前缀。

翻译:可燃性:基本可燃性等级HB、V-2、V-1、V-0次级可燃性等级5VB,5VAHF-1,HF-2,HBFVTM-2,VTM-1,VTM-0笔记:基本等级:主要根据火焰大小分类次级等级测试方法:如5VB,5VA,在燃烧的材料下放棉花,燃烧时的渣会使棉花燃起来就为5VA,燃不起来就是5VBVTM-2,VTM-1,VTM-0防火级别等同于V-2、V-1、V-0VTM为超薄片的含义,如马达上的绝缘纸在塑胶资料库中的火焰等级,笔记:可燃性等级看表中圈起部分(表格同表8)翻译:RIT:电气RTI,与关键电气绝缘特性联系在一起。

认可标志-用于UL认可服务Recognition・Service
•认可服务主要是针对元器件和材料实施的一种安全认证程序。
•认可服务所认可的元器件会被组装在成品中,所以元器件的使用有一定的许可条 件(Conditions of Acceptability).开关、电源、印刷板、电阻、变压器、电线、 插头、塑料材料等都是认可对象。
向工厂提供检验报告和差异通知(如有) UL工厂检验人员离开制造工厂

UL跟踪检验服务
跟踪检验服务的种类: 按照产品类别的不同,跟踪检验服务的实施方式大致分 成两大类(L类与R类)。跟踪检验细则中的授权页会 说明该文档内的产品是属于L类(type L)或是R类 (Type R)。通常R类产品的跟踪检验频率为每季度至 少一次。L类产品的跟踪检验频率取决于制造商使用 UL标签的数量。不同类别的产品在每季度的受检次数 有不同的要求。产品的检验频率在“加强检查 (Increased Monitoring Process,简称IMP)”的状态下 会有明显的增加。IMP通常针对不能按UL要求生产带 有UL标志的产品制造商。IMP是一个阶段性的特殊跟 踪检验程序。在UL确认制造商能按UL要求生产带有 UL标志的产品后,IMP会被取消。

Number of independent busbars2. Minimum load current in a feeder3. Maximum load current in a feeder4. Maximum load current in a busbar5. Biggest CT primary winding6. Minimum short-circuit value (phase to phase) in a busbar7. Voltage used (Yes or No)3.2 Idiff_Ibias Setting calculation spreadsheetEnter in the Idiff_Ibias spreadsheet the 7 values here above listed and you’ll be able to choose thevalues hereafter listed.It is important to know that if the minimum internal fault detection is set below the maximum load an additional criterion such as voltage must be used.3.3 Differential Busbar Protection1. ID>1 (from 5 A to 500 A (primary value)) as high as possible2. Slope k1 (ID>1) (from 0% to 50%), recommendation is 10%3. ID>2 (from 50 A to 50000 A (primary value)) as low as possible4. Slope k2 (ID>2) (from 20% to 90%), recommendation is 60% (50% for China)5. IDCZ>2 (from 50 A to 50000 A (primary value)) as low as possible6. Slope kCZ (IDCZ>2) (from 0% to 90%), recommendation is 30% (25% for China)7. ID>1 Alarm Timer (from 0 to 100 s) shall be greater than the longest protection time (such asline, overcurrent, etc…)8. Phase comparison threshold recommendation depends on the number of infeedsExplanations of the values:1. ID>1 shall be higher than 2% of the biggest CT to not detect noise coming from it and lessthan 80% of the minimum load of a feeder to detect the minimum load imbalance in case of aproblem in that particular feeder.2. Slope k1 recommendation is 10% to meet 10Pxx current transformers3. ID>2 shall be below twice the maximum load for the phase comparison algorithm to pickup theload and if possible below 50% of the minimum fault to be sub-cycle (80% otherwise) and if novoltage criteria is used above 100% (and when possible 120% to allow 20% margin) of thebiggest load to not maloperate in case of CT short-circuited or open circuitNote: voltage criteria can be used for single busbar only in one box mode.and less than 80% of the minimum fault current to operate sub-cycle for the minimum fault (and 50% when possible to be sure to always operate in 13ms)4. Slope k2 (ID>2)a. Recommendation is 60%To be always stable in the worth CT ratio conditions (between the biggest CT andthe smallest CT).b. Recommendation is 50% for ChinaIn China, the requirement is to be able to detect a resistive fault equal to 50% of thebias current.5. IDCZ>2 same as ID>26. Slope kCZ (IDCZ>2)a. Recommendation is 30%kCZ depends on the number of busbars:•n busbars (Independent busbars)• A minimum internal short-circuit value (Icc min (1 busbar))A maximum load for a busbar (IloadMax (1 busbar)).••when all these buses are independent (bus sectionalizers open)•the maximum load is on all the buses (biggest bias current)•The internal short-circuit value is minimum.During the internal fault:•the bias current is: Icc min (1 busbar) + (n-1) x IloadMax (1 busbar) •the differential current is: Icc min (1 busbar)Thus the biggest slope for the Check Zone to detect the fault is: ________________Icc min (1 busbar)________________________((Independent busbars - 1) x IloadMax (1 busbar)) + Icc min (1 busbar)If for example:There are 3 buses and Icc min = IloadMax, the slope must be below 33%Case Half-Breaker Scheme:P746 has to be able to trip for a fault that is counted twice by the Check Zone (forexample one and half circuit breaker substation).For a one and half breaker scheme there are:• 2 busbars (Independent busbars)• A minimum internal short-circuit value (Icc min (1 busbar))•A maximum load for a busbar (IloadMax (1 busbar)).The worst case is: •when the Fault (Icc) is split in 2 and goes as well through the opposite busbar •the maximum load is on the 2 buses (biggest bias current) • The internal short-circuit value is minimum.During the internal fault: •the CZ bias current is: 2 x Icc min (1 busbar) + 4 x IloadMax (1 busbar) •the CZ differential current is: Icc min (1 busbar)Thus the biggest slope for the Check Zone to detect the fault is:___________Icc min (1 busbar)___________(4 x IloadMax (1 busbar)) + 2 x Icc min (1 busbar)If for example:Icc min = IloadMax, the slope must be below 17%b. Recommendation is 25% for ChinaIn China, the requirement is to be able to trip for a resistive fault that is counted twiceby the Check Zone (for example one and half circuit breaker substation).7. ID>1 Alarm Timer to not operate for an external fault shall be greater than the longestprotection time (such as line, overcurrent, etc…)8. Phase comparisonPhase comparison is used to define the minimum current to be included in the phasecomparison blocking algorithm. We cannot consider any level of current in phase comparison because even for an internal fault some small currents can flow out (this situation depends on fault impedance).The requirement for phase comparison minimum threshold is to be able todetect a through fault that is fed by the infeeds;It depends on :•The minimum internal short-circuit threshold (ID>2)•The maximum number of infeeds and their CT primary nominal currentsThe worst scenario is when the CT is fully saturated and the differential algorithm picks up on the ID>2 threshold. The phase comparison must block the trip by detecting the incomingcurrents:We assume the infeeds will contribute to the ID>2 fault in proportion to their CT primarynominal current (worst situation).Then we need for each infeed , phase comparison threshold to be lower than :ID>2 x (In CT / Σ(In CTs infeeds))And Phase comp.= ID>2 / (In CT / Σ(In CTs infeeds)) / In CT,So for any infeed, Phase comp. = ID>2 / Σ(In CTs infeeds))We take 80% of this value so that to keep sufficient margin. Recommended setting is then : :Phase comp. = 0.8 x ID>2 / Σ(In CTs infeeds)Phase comp. setting % = 100 x 0.8 x ID>2 / Σ(In CTs infeeds)4 87BB SETTINGS (COMPENSATED EARTHED NETWORK SCHEMES)4.1 Sub-station featuresOnly 4 values have to be known:1. Maximum load current in a feeder2. Minimum phase to phase fault current (Ph-Ph min.) in a busbar3. Maximum single phase steady state faulty current (Ph-N Max.) in a busbar4. Number of independent busbars5. Maximum number of infeeds4.2 Differential Busbar Protection9 values have to be chosen:1. ID>1 (from 5 A to 500 A (primary value)), recommendation equal to 1,2 x (Ph-N Max.)2. Slope k1 (ID>1) (from 0% to 50%), recommendation is 10%.3. ID>1 Alarm Timer (from 0 to 100 s) shall be greater than the longest Busbar protection time4. Slope k2 (from 20% to 90%) but recommendation 65%.5. ID>2 (from 50 A to 50000 A (primary value)), recommendation is:6. Lower than 0,8 x (Ph-Ph min) and Higher than 1,2 x Iload Max and if possible equal to 6 x(ID>1).7. Slope kCZ (from 0% to 90%) but recommendation 30%.8. IDCZ>2 (from 50 A to 50000 A (primary value)), recommendation is:9. Lower than 0,8 x (Ph-Ph min) and Higher than 1,2 x Iload Max and if possible equal to 6 x(ID>1).10. Phase comparison recommendation is around or below 50%Explanations of the values:1. ID>1 shall be higher than 120% of the highest phase to neutral fault to not operate in case ofphase to neutral fault.2. Slope k1 recommendation is 10% to meet 10Pxx current transformers3. ID>1 Alarm Timer to not operate for an external fault shall be greater than the longestprotection time (such as line, overcurrent, etc…)4. Slope k2 (ID>2) recommendation is 65%To be always stable in the worth CT ratio conditions (between the biggest CT andthe smallest CT). 60% is OK as long as the CT ratio is less than 5.5. ID>2 shall be lower than 80% of the minimum phase to phase fault current to operate sub-cyclefor the minimum fault and higher than 120% Iload Max (120% to allow 20% margin) and ifpossible equal to 6 x (ID>1) to be insensitive to the worth CT saturation.6. IDCZ>2 same as ID>27. Slope kCZ (IDCZ>2) recommendation is 30%The requirement is to be able to trip for a fault that is counted twice by the CheckZone (for example one and half circuit breaker substation).5 50BFInternalInitiationTBF2 should be equal to the maximum opening time + 30 ms*5.1.2 External initiation3. Local retrip delay tBF34. Bactrip delay tBF4TBF4 should be equal to the maximum opening time + 30 ms**: In case of external relaying, add the relay additional closing time.Important note: if the external trip command is not longer than TBF4, add a dwell gate set longer than TBF4 in the PSL.Note: The CB fail alarm is raised as soon as tBF1 or tBF3 are reached.6 DEAD ZONEFor each Terminal connected to a Feeder Circuit Breaker (but not on the coupling)6.1 Terminal SETTINGSFor the phase:I>DZ must be below 80% of the minimum Dead Zone fault (and if possible bigger than the maximumload).I>DZ Time delay must be at least 50ms if the CB status positions are used (any value otherwise)For the Neutral (if used):IN>DZ must be below 80% of the minimum Dead Zone earth fault.IN>DZ Time delay must be at least 50ms if the CB status positions are used (any value otherwise)Important note:When a dead zone fault occurs and the bias current flowing through the busbar is small, there could be a maloperation of the 87BB.To prevent that, it is recommended to enable an additional criterion such as voltage (voltage criteria can。
