WBB-36说明书(汉化版)
表表五（WBB-36B D型装置通道配置）5.1装置的启动元件启动元件作为所有保护功能的开放元件，起着重要的作用，本装置设有两个启动元件：突变量启动元件及电流辅助启动元件。
突变量启动元件利用相电流差突变量来计算，判据为：I =|（l （k）-l （k-N））-（l （k-N）-l （k-2N））|>IQD（N=12）;其中为A，B，C中的任一项。
辅助启动元件为过流启动元件或零序过流启动元件，具体判据为：I >min（IL1 , IL2定值）（在相应的保护功能压板投入情况下）；3IO>IJO定值（在相应的保护功能压板投入情况下）；（C型）3I0>min（101,102,103定值）（在相应的保护功能压板投入情况下）；（D型）其中为A，B，C中的任一项。
5.2复合电压元件复合电压元件由正序低电压和负序过电压经或门构成，变压器三侧电压均可作为闭锁电压引入，另外，可通过开入端子X70（对侧复压闭锁开入）和X69（另侧复压闭锁开入）选择由对侧/另侧复压元件来开放本侧电流保护，对应的，控制字中有相应的选择功能，可选择某一侧复压闭锁或多侧复压闭锁，选择多侧复压闭锁时，开放条件为”或”门,即任一侧复压满足开放条件即开放保护，I段和n段电流保护均可由控制字选择带或不带复合电压闭锁。
5.3两段过流元件设有复压过流I段和复压过流II段两块独立压板投/退保护功能。
启动元件动作后，装置进入两段相间过流判别。
本装置中复压过流I段设置了两个可以独立整定的延时时间，II段也设置了独立的延时时限，可通过控制字选择不同时限跳不同的开关。
装置在执行两段过流判别时，各段判别逻辑一致，其动作条件如下：1）I >Idn ; Idn为n段电流定值（n=1,2）, I为最大相电流2）T>Tdn ; Tdn 为n 段延时定值（n=1,2,3）3）相应于过流相间的方向条件及复合电压条件满足（根据控制字的设置）过流I段可选择带方向，方向可选择指向变压器或母线.5.4两相式、三相式电流元件装置可根据控制字的设置，实现两相式或三相式保护方式，区别在于：两相式保护方式：弓I入IA , IC两相电流及假B相电流IB = -(IA+IC)到本装置，装置电流保护I段、II段均为两相式(只反映IA、IC两相电流)，山段为三相式，主要是为了提高在经Y/ △变压器，在△侧故障III段保护的灵敏度。

东崎电气接近开关使用说明书
接近开关使用说明书感谢您对广东东崎电气有限公司产品的信赖，当您使用我公司产品时请务必参阅本说明，以免因操作失误而造成不必要的损失。
例：TKI-12N4C表示直插式插头连接型,直流电感式接近开关，外形为M12圆柱型，NPN常开，动作距离为4mm，最大输出电流为200mA.二、距离的设定※开关的动作距离请设定在80%检测距离（Sn）内，以免开关工作受温度、电压等影响。
※当检测其它金属时，开关有不同的动作距离。
(图1)※当开关用作测量动作频率或其它高速场合，请将开关的动作距离设定在1/2检测距离(Sn)，开关在此位置可获得最大的动作频率。
※电容式接近开关的动作距离设定，请参阅电容式接近开关的使用说明。
(见五)不锈钢铬镍铜铝二、接线图PNP(直流型)三、串联及并联NPN(直流型)直流二线型检测距离交流二线型(图1)电源电源交流串联交流并联若电源电压为220V，且串联数在3个以内，可使用上图的接法，否则请按下图方法通过继电器进行串联。
并联的开关A和B，若检测体接近开关A，开关A动作，负载电流流过开关A，开关A（B）两端电压降为10V，若此时检测体再接近开关B，因开关两端的电压为10V，开关B会因电压不足而不动作，只有当关闭开关A，使A（B）两端的电压升高至使用电压，开关B才动作，开关A关闭与开关B动作的时间间隔约为10mS，因而当需要多个接近开关并联时应注意开关相互之间的影响，一般请按下图通过继电器进行并联。
电源AC 电源※直流电源必须使用绝缘变压器，请勿使用自耦变压器；※电力线、动力线通过开关引线附近时，为防止开关误动作和损坏，请使用金属配管线。
四、注意事项※交流型开关,若电源电压为110V时,串联必须经过继电器使用；※交流型开关必须经过负载接电源,若直接将开关接电源会损坏开关。
电源AC 电源×错误接法√正确接法※接近开关的引线长度请在200米以下，以免电压降过大。
五、电容式接近开关的使用说明※电容式接近开关不仅能检测金属，而且能检测塑料、玻璃、水、油等物质，因各种检测体的导电率和介电常数、吸水率、体积的不同 故相应检测距离也不同，对于接地的金属可获得最大的检测距离。

The Carousel rotates materials 360° with the assistance of an operator. Now loading and unloading operations can be done more efficiently; minimizes fatigue and risk of back injury. The carousel may be added to an existing work bench, scissor table, or simply placed on the floor. Constructed from two pieces of rolled structural angle (3/16" thick). A series of roller bearings transfer the load smoothly and evenly to the supporting surface. Four guide rollers keep the rings aligned.

1、技术参数1.1 产品型号意义注：※前的项目选型时必须标注，※后的项目为选择项目，不要时可省略，但顺序不可颠倒。
表1.11.2 结构1．2．1 361普通型结构图图1.11．2．2 361防爆型结构图图1.21.3 主要技术参数表1.21．4 安装尺寸图1.3注：表中h1是输出轴位于最下端时的尺寸，H2是拆卸护罩所必须的尺寸，R是手动曲柄操作所必须的尺寸，在设计安装时应予以考虑。
2、工作原理3610系列电子式执行器是以220V单相交流电源作为驱动电源，接受来自计算机、调节器或操作器4～2 OmAd·c、或1～5 Vd·c输入信号来工作的电子式执行机构。
电子控制单元采用集成电路制做，被设计成匣子形式，并用树脂浇铸固化，称为控制模块，本身具有伺服功能。
当控制模块接受的变化输入信号4～2OmAd·c（或1～5 Vd·c）和来自反馈机构的开度信号进行比较、放大后，向消除其差值的方向驱动和控制电机。
电机的旋转通过减速机构把动力传递到输出轴上，使其上、下运动，同时通过反馈机构带动电位器转动，电位器的动作变换成电气信号后，作为开度信号反馈给控制器。
当输入信号和开度信号的差值达到设定的灵敏度范围时，电机停止转动，起到定位调节作用。
3、接收、搬运及保管3．1 接收、搬运警告执行器系重量物体，使用时应注意以下事项，否则可能导致重大人身伤害事故。
●应按照劳动安全卫生法，使用符合要求的提升机械进行卸货、搬运。
绝对不许进入吊起的货件下或在吊件下操作机械。
●设备用纸盒箱包装时，如受潮，会使包装强度下降，所以一旦纸盒箱受潮吊卸必须注意。
●避免受到冲撞、滑落等急剧的冲击。
3．2 保管●在安装之前最好在原包装状态下保管。
●请勿在以下场所保管：(1)可能淋到雨水的地方(2)60℃以上的高温环境(3)灰尘大的环境(4)湿度高的环境●避免受到冲撞、滑落等急剧的冲击。
●从检查打开包装后到开始往阀上安装前，最好再按到货时的包装状态保管。

Doing so may result in oil or water entering the Switch interior. (The IP67 degree of protection specification for the Switch refers to water penetration while the Switch is submersed in water for a specified period of time.)•Always attach the cover after completing wiring and before using the Switch. Also, do not turn ON the Switch with the cover open.Doing so may result in electric shock.MountingUse four M5 screws with washers to mount the standard model. Be sure to apply the proper torque to tighten each screw. Mounting Dimensions (M5)•To change the angle of the lever, loosen the Allen-head bolts on the side of the lever.•The operating position indicator plate * has protruding parts which engage with the lever, thus allowing changes to the lever position by 90°.•The back of the operating position indicator plate * has noprotruding parts. If this plate is turned over and attached, any angle within a 360° range can be set. Do not turn over the plate, however, when using the D4B-@N as a switch with a certified direct opening mechanism. For an SUVA- or BIA-certified application, make sure that the lever engages with the operating position indicator plate securely so that the lever will not slip.*The operating position indicator plate: Refer to page 5. Changes in Head Mounting PositionBy removing the screws on the four corners of the head, the head can be reset in any of four directions. Make sure that no foreign materials will penetrate through the head.Changing the Operating Direction Switches with Roller LeversThe operating direction of the lever can be easily changed without using any tools.

3.结构概述
上海富继电气有限公司限位开关由主轴通过齿轮减速系统
一具有可调凸轮片组组合的凸轮轴及对称并列布置在其两
侧的微动开关构成的控制系统三者结为一体安装在防护等
级为IP64的外壳内，其外形及安装尺寸见图1。
图1LX36-8
限位开关外形图一。
4.参数
4．1基本参数限位开关的基本参数见表1 表1
4．2接通分断限位开关的接通与分断能力见表2 表2
4．3电寿命限位开关的电寿命在相应于表3所列的使用条件下，不需修理式更换零件的负载操作闪数为10万次。
表3
4．4机械寿命限位开关的机械寿命为100万次；4．5极
限速度操动限位开关输入轴端的最高转速150r/min；
5.标号
5．1接点标号控制回路触头的接点标号见图2所示。
6.凸轮片角度及其调整
6．1凸轮片工作角度凸轮片的型式有两类八种，即第1类有la、ld……:g等七种。
第II类只有一种，其工作角度及限位开关主轴相应转数见表4。
6．2凸轮片组工作位置的调整凸轮片组工作位置的调整，应按各控制回路的工作程序要求进行。
而它们各自的工作程序的起点和终点位置，是由各凸轮片组（二个）构成的不同夹角来实现的，所以只有在确定各个凸轮片组工作角度的前提下，才能进
行调整。
例如：某触头闭合区间的工作起点角度为43.7°、
终点角度为138.9°时,采用II轮凸轮片,如何调整凸轮片组?
由于II型凸轮片的凸起部件窄,目测明显,调整较易,所以起
点的角度值取43.7°-13.7°=30°终点的角度值取
138.9°+13.7=152.6°.然后使刻度盘上30°的起点刻度线与支
撑的缺口相对准见图3.使应调凸轮组中的一个凸轮部位中
心调至与两个支撑板缺口成为一条直线即可,另一个凸轮片
也按此方法调定其终点工作位置。
关于各控制回路触头闭
合起点和终点区间的确定，可用刻度盘“0点”为统一计算原
点，按表4所列数据按比例分配法计算得出。
6．3调整及
注意事项6．3．1调整凸轮片的调整操作方法见图4。
6．3．2注意事项a、松动圆螺母时，不能使凸轮片处于自由转动状态。
b、凸轮组全部调动并经复查无误后，必须用圆螺母固紧，以防
松动错位。
7.安装与检查
7．1安装7．2产品的安装限位开关的安装形式有两种：
a、轴端法兰盘安装；
b、壳体底面水平安装。
无论采用何种
形式的安装，必须保证起重机旋转机构的轴线与限位开关
输入轴线相重合，以防产生安装误差引起的附加应力，其
安装尺寸见图1。
7．1．2电线电缆的安装该限位开关设
有三个导线进、出孔，其位置及尺寸见图1。
被选用的进出
孔在导线安装后，其孔端须密封处理，符合IP64要求。
未
被利用的孔，也必须注意将螺塞旋紧。
7．2检查7．2．1
安装前的检查安装前必须对限位开关的转动灵活性和其它部件是否处于正常工作状态进行检查。
7．2．2运行前的检查限位开关开始投入运行前，必须首先对限位开关予以调整的控制系统是否能准确地控制进行核查并进行必要的再调整。
8.维修8．1维修限位开关的维修周期应与起重机电气系统
的维修同时进行。
除做必要的检查维修外，应对具有机械
运动磨擦部位涂ZG-3钙基润滑脂。
并更换已损坏的触头元
件（微动开关）。
说明：对于选用超出基本规格转速比的
用户可特殊定货。
