带外串联间隙型线路避雷器说明书
带外串联间隙型线路避雷器安装使用说明书广州华盛避雷器实业有限公司1用途及特点带外串联间隙型线路避雷器（以下简称避雷器）与线路绝缘子（串）并联安装使用，特别在雷电活动强烈或降低杆（铁）塔接地电阻困难的线段，可有效降低线路雷击跳闸事故率。
避雷器具有放电分散性小、密封性能好、防爆、耐污、体积小、重量轻、运输及安装方便等优点。
2 工作原理因串联间隙的隔离作用，在系统正常运行时，本体基本处于“休息”状态，大部分工频电压由串联间隙承担，由于串联间隙对工频和操作过电压的耐受特性，在工频和操作过电压的作用下，避雷器不动作，只有在雷电过电压的作用下，串联间隙才击穿放电，避雷器动作，限制了雷电过电压，从而确保了被保护的线路绝缘子（串）不发生闪络，并在雷电冲击过后，串联间隙可靠切断工频续流，系统恢复正常运行。
3 正常使用条件a)环境温度不高于+45℃，不低于–40℃；b)太的辐射；c)海拔高度不超过2000m；d)电源频率不小于48Hz，不超过62Hz；e)地震烈度8度及以下地区；f)最大风速不超过35m/s；4 型号及含义5．技术性能避雷器主要技术性能见表1。
6．验收试验用户应对交货的避雷器进行验收试验：⑴按装箱单检查随机文件及附件，应齐全。
⑵测量本体直流1mA参考电压及0.75倍直流1mA参考电压下泄漏电流应符合表1规定（注意：在潮湿及表面污秽时，应采用屏蔽法测量）。
⑶测量串联间隙距离应符合表1规定。
7．贮存避雷器应贮放在环境温度为–40℃~ +45℃、干燥通风、无酸碱及其它有害物质的库房中保存。
8．安装⑴避雷器外形结构及安装尺寸，见图1。
⑵避雷器与被保护的线路绝缘子（串）并联安装使用。
可悬垂安装、水平安装、斜装或其组合方式，依据塔型及实际需要确定，见图2~9。
(a) 悬垂安装悬垂安装于直线塔时，安装支架（杆塔为用抱箍安装于水泥杆上的单支角钢，其悬挂避雷器端用钢索斜拉，铁塔为安装于塔横担上的三角支架，门型杆塔、酒杯型铁塔、猫头型铁塔等单回路塔的中相则可为安装于塔顶的单支角钢）应沿线路方向抬高伸出，35kV、110kV、220kV避雷器与线路绝缘子（串）间的净距离最小值分别为360mm、800mm、1520mm，避雷器与输电导线宜采用并沟线夹或T形线夹连接，安装好后避雷器的最低点应不低于同相输电导线。

5．平衡调整1. 将四个传感器的信号线接在接线柱上，让所有短路块插在K1、K2、K3、K4的左边并把电位器拧至电阻值适中，记下四个传感器接线柱与承载器上传感器位置的对应关系，把输出线接往仪表。
例如：XP1：左上角XP3：右上角XP2：左下角XP4：左下角2. 依次在承载器四个角放置同一重物，记录四个传感器在显示器上不同的重量值，从大到小排列。
3. 让所有短路块插在K1、K2、K3、K4的右边，在承载器最大的一角电位器往逆时针方向拧，承载器最小的一角电位器往顺时针方向拧。
4. 重复第2步和第3步直到承载器四个角放置的重物在仪表上显示一致。
备注：a. 在调试中的重物应大于满量程的20%，否则秤的精度将会降低。
b.在调试中发现接线柱的电位器拧至电阻值最小或电位器拧至电阻值最大，还不能调好秤的平衡，应检查四个传感的灵敏度离散性是否太大。

These limits are designed to providereasonable protection against harmfulinterference when the equipment isoperated in a commercial environment. Thisequipment generates, uses, and can radiateradio frequency energy and, if not installedand used in accordance with the instructionmanual, may cause harmful interference toradio communications. Operation of thisequipment in a residential area is likely tocause harmful interference in which casethe user will be required to correct theinterference at his own expense.•Any changes or modifications to the unit not expressly approved by ALTINEX, Inc. couldvoid the user’s authority to operate theequipment.2 Tilt 'N Plug Jr. ™'s are members of a family of compact interconnection solutions designed for installation into a table in a presentation system. These products are designed for mounting into a table, podium, or other furniture to provide a way of connecting audio/visual equipment on top of the furniture to a presentation system below the furniture. All use the same core element; a multimedia input plate that can be "tilted" open when needed and pushed closed when not needed.The TNP122/142/ 152/162 incorporates two Tilt ‘N Plug Jr.™ individual tower modules, the TNP123 incorporates three individual modules and the TNP124 incorporates four individual modules. Each module can be operated independently; the TNP124/152 can service from one to four users simultaneously. During installation of the TNP122/123/152/162, the individual tower modules can be reversed to face opposite directions through a simple field-modification to the bezel. This alternative configuration is handy for applications in which the TNP122/123/152/162 needs to service two sides of a table simultaneously. Note that the TNP142 is the same as a TNP122 but with the modules factory-installed facing in opposite directions.The TNP131 is the same as a TNP121 but with a round bezel instead of square. The TNP162 is a dual module configuration with a TNP121 module and a TNP151 module side by side. The TNP124 is a quad TNP121 with two rows of twin modules facing in opposite directions; the modules in the TNP124 cannot be reversed.The TNP421/431/441/451 are international models with power connectors for specific countries. The TNP421 has a standard "Schuko" receptacle formost European countries, the TNP431 is for the U.K., Singapore and Hong Kong, the TNP441 is for Australia and New Zealand and the TNP451 is for South Africa. Versions of the TNP121/122/123/124/131/142 with a universal IEC320 connector instead of the U.S. power connector are also available.All signals are passed through the input plate to cables on the underside of the table without passing through any circuitry. In some applications, the use of additional ALTINEX signal management solutions —such as computer video interfaces, distribution amplifiers, and switchers — may be desirable.The input plate on the Tilt ‘N Plug Jr.™ is accessed by pushing down on the top cover, which will then auto-tilt open into view with help from a pneumatic spring inside the unit. Once opened, the input plate remains securely in place. The input plate is hidden by pressing down on the top cover until the latching mechanism engages. In its closed position, the top panel lies flush with the table top, held in place by the latching mechanism.All Tilt ‘N Plug Jr.™ solutions come with a standard top and bezel offering a high quality matte black finish.Other optional finishes — Fine Antique Brass, Satin Blush White Gold, Fine Antique Chrome, Antique Copper, Crystallite Copper, Bright Gold, Bright Silver and Brushed Aluminum— are available on a custom order basis. Also, special bezel configurations may be available for large custom orders. Please contact an ALTINEX representative to discuss custom options.3 Specifications are subject to change.See for up-to-date information.MECHANICAL TNP121/131/TNP151 WidthDiameter (TNP131)4.60 in.

Always confirm dimensionsbefore cutting to insure that specificationshave not changed.Step 2.Insert the your Tilt ‘N Plug Jr.™ into the table cutout.Step 3.Place the support brackets under the table and place them between the supportmount grooves on the side of the your Tilt‘N Plug Jr.™. Attach the brackets to thegroove at the desired height and securethem to the bottom of the table using the#6-32 screw. There are two supportbrackets for each module, one for eachside of the unit (see Diagram 3). For theTNP124 model, only the outer sides ofeach module will have a bracket placed inthe grooves for a total of four.Step 4.Secure the cables by using the provided cable clamps and screws. Pass the powercord from the bottom of the housing andattach it to the table using the cable clampand screw supplied with the your Tilt ‘NPlug Jr.™. Leave enough slack in theservice loop to allow for easy opening andclosing, but not too much as to causeexcess drooping of the service loop.Step 5.Connect the appropriate cables with the correct input connectors on the bottom ofthe unit.Step 6.Once you have applied power and connected the proper cables on the bottomof the unit you may raise the unit. To raisethe Tilt ‘N Plug Jr.™ into position, pushdown on the front of the top cover; thelatching mechanism will then release,allowing the pneumatic spring to raise itinto position.Step 7.To lower the unit, push on the top of the Tilt ‘N Plug Jr.™ until it locks into place.8 The Tilt ‘N Plug Jr.™ supplied unit was carefully tested and no problems were detected. However, we would like to offer the following suggestions:•Please make sure that the highest quality network cables are used.•Make sure that no cable or power cord is damaged or pinched. If there has beendamage, then do not use the Tilt ‘N Plug Jr.™.Immediately contact the ALTINEX CustomerService Department to have the unit repaired.9 9.0 LIMITED WARRANTY / RETURN POLICYPlease see the Altinex website at for details on warranty and return policy.9.1 CONTACT INFORMATIONALTINEX, INC.592 Apollo StreetBrea, CA 92821 USATEL: 714-990-2300TOLL FREE: 1-800-ALTINEXWEB:E-MAIL:*********************FAX: 714-990-3303。

耀华串联式接线盒使用说明
一、概述
本接线盒采用串联调整电位器的方式来修正四角误差。
采用20Ω高精度多圈（20圈）电位器。
接线方式为压接、焊接可选。
二、预调
1、在不接传感器的情况下，用数字式万用表电阻档测量各电位器的电阻值。
表棒搭在OUT接线端子的E+和X接线端子(X为A、B、C、D、E、F、
G、H)的E+上即可测得Xr电位器的电阻值。
2、把各个电位器的电阻值都调成一样。
（顺时针调节电位器，则电位器的电
阻值变大；逆时针调节电位器，则电位器的电阻值变小）
三、接线
E+表示供桥正；E-表示供桥负；IN+表示信号正；IN-表示信号负；接屏蔽线的屏蔽层。
A、B、C、D、E、F、G、H接线端子接传感器，OUT接线端子接仪表。
四、修正四角误差
Xr电位器对应的是X接线端子所连的传感器（X为A、B、C、D、E、F、
G、H）。
顺时针调节电位器，则电位器的电阻值变大，所对应的传感器所占
的比重也变小。
逆时针调节电位器，则电位器的电阻值变小，所对应的传感器所占的比重也变大。
（如果某个角偏大，则应顺时针调节对应的电位器；如果某个角偏小，则应逆时针调节对应的电位器）
