It is used for filling and draining applications, to protect pumps against dry-running, tanks against overflow and for signalization of the status of the monitored liquid level.Application exampleOperating mode with three electrodesThe CM-ENS.2x measures the electrical resistance of the liquid between two immersion electrodes and a referenceoutput relay is energized until the MAX-electrode becomes wet. Then it is de-energized and not re-energized until the MIN-electrode becomes dry. If the drain function is selected, the output relay energizes as soon as the MAX-electrode becomeswet. It remains energized until the liquid level has dropped below the MIN-electrode.Operating mode with two electrodesIf only one level should be controlled, only the MAX-electrode shall be connected at the monitoring relay (see pictureOperation with two electrodes).original state once the MAX-electrode gets in contact with the monitored medium.original state once the MAX-electrode is no longer in contact with the monitored medium.4 - Liquid level monitoring relay CM-ENS.2x | Data sheetData sheet | Liquid level monitoring relay CM-ENS.2x - 5Cascading of several devicesWith the CM-ENS.2x it is possible to use two devices in one tank. This enables, to realize a pre-warning with additional electrodes. In this way, two additional alarm outputs for exceeding or dropping below the normal level can be implemented in addition to the filling levels MAX and MIN.

元谷电子，始终是您的最佳合作伙伴！图片展示：特点：● UL , CE和TUV安全认证● 最大切换电流30A● 线圈功耗930mW● 动作功耗520mW● PC板和快速端子双面接型逆变焊机 IGBT模块的选用国产常规逆变焊机，通常;1.工作于3相380V电网电压。
2. 全桥逆变，用2单元半桥模块。
3. IGBT模块选用1200V。
那么用多大标称电流？要依据机型; 负载率; 电路形式来定！下面介绍本人选择的经验仅供参考。
对于采用软开关电路的逆变焊机，基于1. 软开关IGBT 器件的开关电流冲击很小.2. 峰值电流控制使IGBT 器件电流用到极限。
所以计算方法.直接采取额定最大电流除以主变匝比，就是模块承受的峰值电流！举例;型号;ZX7-*** ZX7-315 ZX7-400 ZX7-500额定电流 315A 400A 50 0A反射到模块电流 45A 57 A 71A主变N=7软开关电路选模块 50A 50A 75A硬开关电路选模块 50A 75A 100A以上指优质指标的模块; 例西门子[德]. 海伯伦[韩]. 斯达[中]从上表也可看到焊机的跳挡与模块跳挡有些不适配！如ZX7-400机选50A偏弱，选75A又浪费一些，设计师应该注意到，并在做机时可适当控制。

designed to be compatible with most Wye or Delta systems.In Wye systems, a connection to a neutral is not required.Phase Monitoring Relays protect against unbalanced voltages or single phasing regardless of any regenerative voltages.The relay is energized when the phase sequence and all voltages are correct.Any one of four fault conditions will de-energize the relay.Re-energization is automatic upon correction of the fault condition.An LED indicates normal and tripped conditions.The per-cent phase unbalance is adjustable from 2-10%, and the undervoltage drop-out can be set at 75-95% of operating voltage.The adjustable time delay dropout on undervoltage (0.1-20 sec-onds) eliminates nuisance tripping caused by momentary voltage fluctuations.Output :10A SPDT (PMP) or DPDT

voltage condition is potentially damaging.They monitor either AC single phase (50-400hz) or DC (independent of polarity) voltages.No supply (input) voltage is required.The pick-up voltage setting is user-adjustable from 85-115% of the nominal voltage rating.The drop-out voltage setting is fixed at 3% below the pick-up voltage setting.The relay energizes when the monitored voltage is above the pick-up setting.The relay de-energizes when the monitored voltage is below the drop-out setting.The time delay on drop-out is fixed at 50ms.Output :10A DPDT @ 240VAC/30VDC.Dimensions :1.7”x 2.4”x 2.9”.ALTERNATING R ELAYSUsed in special applications where the optimization of load usage is required by equalizing the run time of two loads.They are also used where additional capacity is required in case of excess load requirements.This alternating action is initiated by a control switch, such as a float switch, manual switch, timing relay, pressure switch, or other isolated contact.Each time the initiating switch is opened, the output relay contacts will change state, thus alternating the two loads.Tw o LED indicators show the status of the output relay.As listed, these units come with a three position selector switch.This allows the unit to alternate the two loads as normal, or lock the relay to one load or the other.By locking the Alternating Relay to one load, the other load can be

EVR150CI继电器规格书1、技术参数注）①.在微小负载水平下能够通断的下限目标值。
该值有时会根据通断频率、环境条件、所期待的可靠水准发生改变，因此在使用时，推荐在实际负载下进行确认②. 寿命测试通断时间：通0.3s,断2.7s，使用二极管时，触点复位时间可能会延迟，电寿命可能会下降，敬请注意。
2、外形尺寸图技术要求：1、未注公差按公差列表。
2、外观无脏污、划伤等不良，标签需正确。
3、安装底部平面度要求：≤0.5mm。
4、出货包装满足功率继电器出货包装标准要求。

2) 施加的电压超过最大施加电压时，线圈中的异常升温会缩短绝缘涂层的寿命而发生线圈烧损和层间短路，因此请务必注意。
另外，使用环境温度的范围也请注意不要超过使用范围。
3) 对于这款继电器，如果额定电压（或电流）长时间施加到线圈和接点上，然后关闭并立即打开，则线圈温度和线圈电阻将比平时高。
这意味着操作电压也比平时高，超过了额定值（“热启动”）。
在这种情况下，应采取适当措施，例如降低负载电流和通电时间或限制使用环境温度，防止施加额定操作电压以上的线圈电压等。
4) 线圈长期连续通电时，受线圈自身发热的影响，会促使线圈的绝缘发生劣化。
5) 额定值中的主触点额定值均为电阻负载时的数值。
使用L/R>1ms 的感性负载（L 负载）的情况下，请与感性负载并行采取浪涌吸收措施。
未采取措施的情况下，可能会造成电气寿命下降、发生切断不良。

【精品】电力系统继电保护课后习题解析第二版
7电力系统继电保护课后习题答案1绪论1。
1电力系统如果没有配备完善的继电保护系统，想象一下会出现什么情景？答:现代的电力系统离开完善的继电保护系统是不能运行的.当电力系统发生故障时，电源至故障点之间的电力设备中将流过很大的短路电流，若没有完善的继电保护系统将故障快速切除，则会引起故障元件和流过故障电流的其他电气设备的损坏；当电力系统发生故障时，发电机端电压降低造成发电机的输入机械功率和输出电磁功率的不平衡，可能引起电力系统稳定性的破坏,甚至引起电网的崩溃、造成人身伤亡。
如果电力系统没有配备完善的继电保护系统，则当电力系统出现不正常运行时，不能及时地发出信号通知值班人员进行合理的处理.1。
2继电保护装置在电力系统中所起的作用是什么？答:继电保护装置就是指能反应电力系统中设备发生故障或不正常运行状态，并动作于断路器跳闸或发出信号的一种自动装置。
它的作用包括:1。
电力系统正常运行时不动作;2.电力系统部正常运行时发报警信号，通知值班人员处理,使电力系统尽快恢复正常运行;3.电力系统故障时，甄别出发生故障的电力设备，并向故障点与电源点之间、最靠近故障点断路器发出跳闸指令，将故障部分与电网的其他部分隔离。
1。
3继电保护装置通过哪些主要环节完成预定的保护功能,各环节的作用是什么？答:继电保护装置一般通过测量比较、逻辑判断和执行输出三个部分完成预定的保护功能.测量比较环节是册来那个被保护电器元件的物理参量，并与给定的值进行比较,根据比较的结果，给出“是”、“非”、“0”或“1”性质的一组逻辑信号，从而判别保护装置是否应该启动.逻辑判断环节是根据测量环节输出的逻辑信号,使保护装置按一定的逻辑关系判定故障的类型和范围，最后确定是否应该使断路器跳闸。
执行输出环节是根据逻辑部分传来的指令，发出跳开断路器的跳闸脉冲及相应的动作信息、发出警报或不动作。
1。
4依据电力元件正常工作、不正常工作和短路状态下的电气量复制差异，已经构成哪些原理的保护，这些保护单靠保护整定值能求出保护范围内任意点的故障吗?答：利用流过被保护元件电流幅值的增大,构成了过电流保护；利用短路时电压幅值的降低，构成了低电压保护；利用电压幅值的异常升高，构成了过电压保护；利用测量阻抗的降低和阻抗角的变大，构成了低阻抗保护。
各种继电器图形符号及其作用、特点之欧阳生创编
6.2.4 继电器在机电控制系统中，虽然利用接触器作为电气执行元件可以实现最基本的自动控制，但对于稍复杂的情况就无能为力。
在极大多数的机电控制系统中，需要根据系统的各种状态或参数进行判断和逻辑运算，然后根据逻辑运算结果去控制接触器等电气执行元件，实现自动控制的目的。
这就需要能够对系统的各种状态或参数进行判断和逻辑运算的电器元件，这一类电器元件就称为继电器。
继电器实质上是一种传递信号的电器，它是一种根据特定形式的输入信号转变为其触点开合状态的电器元件。
一般来说，继电器由承受机构、中间机构和执行机构三部分组成。
承受机构反映继电器的输入量，并传递给中间机构，与预定的量（整定量）进行比较，当达到整定量时（过量或欠量），中间机构就使执行机构动作，其触点闭合或断开，从而实现某种控制目的。
继电器作为系统的各种状态或参量判断和逻辑运算的电器元件，主要起到信号转换和传递作用，其触点容量较小。
所以，通常接在控制电路中用于反映控制信号，而不能像接触器那样直接接到有一定负荷的主回路中。
这也是继电器与接触器的根本区别。
继电器的种类很多，按它反映信号的种类可分为电流、电压、速度、压力、温度等；按动作原理分为电磁式、感应式、电动式和电子式；按动作时间分为瞬时动作和延时动作。
电磁式继电器有直流和交流之分，它们的重要结构和工作原理与接触器基本相同，它们各自又可分为电流、电压、中间、时间继电器等。
下面介绍几种常用的继电器。
1. 中间继电器中间继电器是用来转换和传递控制信号的元件。
他的输入信号是线圈的通电断电信号，输出信号为触点的动作。
它本质上是电压继电器，但还具有触头多（多至六对或更多）、触头能承受的电流较大（额定电流5A～10A）、动作灵敏（动作时间小于0.05s）等特点。
中间继电器的图形符号如图6.28所示，其文字符号用KA表示。
中间继电器的主要技术参数有额定电压、额定电流、触点对数以及线圈电压种类和规格等。
选用时要注意线圈的电压种类和规格应和控制电路相一致。

电力系统继电保护课后习题答案
2电流的电网保护2.1在过量（欠量）继电器中，为什么要求其动作特性满足“继电特性”？若不满足，当加入继电器的电量在动作值附近时将可能出现什么情况？答：过量继电器的继电特性类似于电子电路中的“施密特特性“，如图2-1所示。
当加入继电器的动作电量（图中的k I ）大于其设定的动作值（图中的op I ）时，继电器能够突然动作；继电器一旦动作以后，即是输入的电气量减小至稍小于其动作值，继电器也不会返回，只有当加入继电器的电气量小于其设定的返回值（图中的re I ）以后它才突然返回。
无论启动还是返回，继电器的动作都是明确干脆的，它不可能停留在某一个中间位置，这种特性称为“继电特性”。
为了保证继电器可靠工作，其动作特性必须满足继电特性，否则当加入继电器的电气量在动作值附近波动时，继电器将不停地在动作和返回两个状态之间切换，出现“抖动“现象，后续的电路将无法正常工作。
126534op I kI reI 1E 0E2.2 请列举说明为实现“继电特性”，电磁型、集成电路性、数字型继电器常分别采用那些技术？答：在过量动作的电磁型继电器中，继电器的动作条件是电磁力矩大于弹簧的反拉力矩与摩擦力矩之和，当电磁力矩刚刚达到动作条件时，继电器的可动衔铁开始转动，磁路气隙减小，在外加电流（或电压）不变的情况下，电磁力矩随气隙的减小而按平方关系增加，弹簧的反拉力矩随气隙的减小而线性增加，在整个动作过程中总的剩余力矩为正值，衔铁加速转动，直至衔铁完全吸合，所以动作过程干脆利落。
继电器的返回过程与之相反，返回的条件变为在闭合位置时弹簧的反拉力矩大于电磁力矩与摩擦力矩之和。
当电磁力矩减小到启动返回时，由于这时摩擦力矩反向，返回的过程中，电磁力矩按平方关系减小，弹簧力矩按线性关系减小，产生一个返回方向的剩余力矩，因此能够加速返回，即返回的过程也是干脆利落的。
所以返回值一定小于动作值，继电器有一个小于1 的返回系数。
这样就获得了“继电特性”。
