但是也不能完全排除差异情况,因此我们不能担保此处所提供信息的正确性。

会定期检查本手册中的信息,并在以后版本中包括任何必要的修正。

过电流保护设置小心仅在断路器断开时调整参数。

如果在断路器接通的情况下修改参数,则可能会意外使断路器脱扣。

小心当规划项目和考虑选择性时,必须确保断路器上的负载不超过 3WT 产品目录中规定的分断能力。

就某种程度而言,必须设置上游保护设备才能安全地中断这些故障。

2.断路器保护电流值的整定

断路器保护电流值的整定1.脱扣器额定电流,断路器框架等级额定电流1).脱扣器额定电流:断路器脱扣器额定电流指断路器主触点的额定电流值。

2).断路器壳架等级额定电流Inm:指基本几何尺寸相同和结构相似的框架或塑料外壳中能装的最大脱扣器的额定电流。

举个例子:DZ20Y-100/3300-80ADZ表示塑壳式断路器,20表示设计序号,Y为一般型(指的是额定极限短路分断能力级别),100A表示断路器框架等级额定电流,80A表示脱扣器额定电流,3300中3表示3极,300表示热磁脱扣器。

同一系列中有多种壳架等级额定电流,例如DZ20系列中有100、225、400、630、800、1250等壳架等级额定电流。

同一壳架等级额定电流中又有多种脱扣器额定电流,例如100A壳架等级额定电流中有16A、20A、25A、32A、40A、50A、63A、80A、100A等脱扣器额定电流;225A壳架等级额定电流中有100A,125A、160A、180A、200A、225A脱扣器额定电流。

DZ20-100和DZ20-225两种壳架等级中都有100A脱扣器额定电流,但断路器体积外形和分断能力不相同。

2.热磁脱扣、电子脱扣1).热磁脱扣是复式脱扣,它包含热脱扣、电磁脱扣两个功能。

热脱扣是通过双金属片过电流延时发热变形推动脱扣传动机构,用于过载保护;电磁脱扣是通过电磁线圈的短路电流瞬时推动衔铁带动脱扣,用于短路保护。

2).电子脱扣可以有以上所有功能,并可以方便地进行整定。

电子脱扣器就是用电子元件构成的电路,检测主电路电流,放大、推动脱扣机构。

优缺点:热磁脱扣性能稳定且不受电压波动影响、寿命长、灵敏度低;(推荐使用)电子脱扣功能完善、灵敏度高、整定方便、受电源影响、略易损坏。

低压塑壳断路器动作电流整定与故障处理

低压塑壳断路器动作电流整定与故障处理摘要:本文主要阐述了低压塑壳断路器动作电流整定,对低压断路器常见故障进行了分析,并提出了这些故障的一般处理措施。

关键字:低压塑料外壳断路器动作电流整定故障处理低压断路器又称自动开关或自动空气断路器,是低压配电系统中重要的控制电器之一,能承载、接通、分断正常工作电流,亦能接通、短时承载及分断短路电流的电器。

按结构可分框架式断路器(万能式断路器)和塑壳式断路器两大类。

塑壳式断路器型号比较多,如CM1型、HM3型、DZ20型、HSM1型、RM1型、S1N型、S2N型、LJM2E 型等,具有结构紧凑、体积小、分断高、飞弧短、可自行设定保护特性,操作简单等优点,目前广泛应用在配电低压系统中,一般安装在配电变压器低压侧配电箱内,保护线路和电源设备不受损坏。

一、低压塑壳断路器动作电流整定塑壳式断路器的保护系统是热动—电磁脱扣器型,过载长延时动作采用热双金属元件脱扣,短路瞬时动作采用电磁铁系统动作。

长延时动作功能是为了满足过负荷保护的需要,而瞬时动作功能则是为了满足短路保护的需要,配电网中的过负荷和短路现象也都有瞬时性或永久性之分,加之配电网结构往往由多级开关设备组成。

因此,只有同时具备两种功能,才有可能使保护装置的动作具有选择性、速动性、灵敏性和可靠性。

(一)配电变压器低压总断路器的动作电流整定。

1、瞬时脱扣器的动作电流应避开网络中出现的尖峰负荷,并能在最小短路电流的情况下正确动作,一般为控制器额定电流的5-10倍。

如断路器额定电流大于250A 时,瞬时动作电流整定值可在5-10倍中选择,一般在订货时提出要求,由制造厂整定出厂。

2、长延时脱扣器的动作电流可根据配电变压器低压侧允许的过负荷电流来确定。

(二)配电变压器低压分路断路器的动作电流整定。

配电变压器低压分路断路器脱扣器的动作电流应比上一级脱扣器的动作电流至少低一个级差。

具体整定方法如下:1、瞬时脱扣器的动作电流应避开回路中出现的尖峰负荷。

IntroductionThe Shunt Trip and Shunt Trip with Lockout accessories, shown in Figure 1, can be installed in 800–4000 ampere frame Power Break® II circuit breakers. These accessories allow the breaker to be tripped electrically from a remote location.In addition to providing a trip signal to the breaker, the Shunt Trip accessories can be set up to interact with other Power Break II accessories, when used with a MicroVersaTrip Plus™or MicroVersaTrip PM™ Trip Unit. DIP switches on the rear of the breaker Trip Unit can configure the Shunt Trip accessories to activate a Bell Alarm–Alarm Only accessory or a Bell Alarm with Lockout accessory when a s hunt trip occurs. The Accessory Configuration section below describes how this can be done. If the breaker is equipped with a Power+™ Trip Unit, it is configured so that only protection trips will activate a Bell Alarm–Alarm Only or Bell Alarm with Lockout.The catalog numbers for the Shunt Trip and Shunt Trip with Lockout for 480 and 600 Vac are listed in Table 1. Voltage and current ratings in Table 1 are given at the input of the transformer. The voltage and current ratings of the input to the accessory are equal to that of the 120 Vac version of the accessory. Table 2 lists these ratings.OperationApply control voltage to the primary of the supplied step-down transformer. The secondary of the transformer is connected t o terminals 31 and 32 of the terminal strip on the right side o f the breaker.WARNING:480 Vac and 600 Vac Shunt Trip accessories must be used with the supplied step-down transformer.AVERTISSEMENT: Les modules de déclenchement shunt 480 Vac et 600 Vac doivent être utilisés avec le transformateur abaisseur de tension qui est fourni.The Shunt Trip or Shunt Trip with Lockout will cause the circuit breaker to trip when the control voltage is greater than 55% of the rated ac value. Control power to the Shunt Tripmust be removed before the breaker can be closed. Control power to the Shunt Trip with Lockout must be removed for a minimum of 0.25 second before the breaker can be closed.Figure 1.

Table 3 lists the correct transformer primary taps.8.Connect the secondary side of the transformer, marked as the X numbered terminals, to terminals 31 and 32 of the terminal block on the right side of the breaker. Table 3lists the correct transformer secondary taps.WARNING: 480 Vac and 600 Vac Shunt Trip accessories must be used with the supplied step-down transformer.AVERTISSEMENT: Les modules de déclenchement shunt 480Vac et 600 Vac doivent être utilisés avec le transformateur abaisseur de tension qui est fourni.Catalog Number/Control VoltagePrimary Connections Secondary Connections9T58K0042480 V H1, H4➀X1, X29T58K0062600 VH1, H4X1, X3➀ A jumper must be placed from H2 to H3.Table 3.

If the breaker is equipped with a Power+ Trip Unit, the factory default settings, listed in Table 4, can not be changed.The Shunt Trip accessory can be configured to activate the Bell Alarm–Alarm Only or Bell Alarm with Lockout accessories if a shunt trip occurs. The configuration can be changed by removing the Trip Unit from the breaker, setting the DIP switches on the rear of the Trip Unit, and reinstalling the Trip Unit. Figure 4 illustrates the Trip Unit rear DIP switches and their functions. Table 4 lists the switch functions and the factory settings for each.Description of Switch SettingsFollowing are descriptions of the effects of each accessory switch when it is enabled .1.When a Shunt Trip accessory causes the breaker to trip,the contacts of the Bell Alarm–Alarm Only also change state.

Remove the cover from the breaker face.3.Pull the Trip Unit locking lever to the right, then hold the Trip Unit near the battery cover and lift it straight out o f the breaker.4.Refer to Figure 4 and Table 4 to determine the switches t o be changed.5.Push in the appropriate “Enable” or “Disable” side of the switch.6.Confirm all switch settings before reinstalling the Trip Unit in the breaker.7.Pull the Trip Unit locking lever to the right. While holding the lever, carefully align the connector on the rear of the Trip Unit with the connector in the breaker. Press down on the Trip Unit, while holding it near the battery cover.When the Trip Unit is fully seated, slide the locking lever back to the left.8.Reinstall the breaker top cover and tighten the four #10-32screws to 32 in-lb.9.Replace the trim plate and tighten the four #8-32 screws to 20 in-lb.10.Verify that the switch settings are correct by inducingbreaker trips from the Shunt Trip and Undervoltage Release (if present) and checking the responses of the Bell Alarm–Alarm Only and Bell Alarm with Lockout accessories.Test ProcedureTest the Shunt Trip for proper operation with the following procedure.1.Turn off the power to the Shunt Trip.2.Close the breaker contacts.3.Apply at least 55% of the rated ac voltage to the Shunt Trip; the breaker should trip immediately.4.If a Bell Alarm–Alarm Only or Bell Alarm with Lockout is present, ensure that they activate (or do not activate) as selected by the MicroVersaTrip Plus or MicroVersaTrip PM Trip Unit DIP switches.If a Shunt Trip with Lockout has been installed, continue with the following steps:5.After the breaker has tripped and with the power still applied to the Shunt Trip with Lockout, attempt to close the breaker. The breaker should not close nor attempt t o close.6.If a MicroVersaTrip Plus or MicroVersaTrip PM Trip Unit is installed, check that t h e Trip Unit display is active (powered).7.Remove power from the Shunt Trip with Lockout.8.Attempt to close the breaker; it should close as normal.Trouble-ShootingThe following guide is provided for trouble-shooting and isolating c o m m o n problems. It does not cover every possible situation.

If thelockout plunger protrudes out of the accessory, replacethe accessory. If the plunger does not protrude, reinsertthe accessory, ensuring good alignment of the accessoryin the pocket.5.The breaker fails to closeafter control power isremoved from the ShuntTrip with Lockout.Control power was not removedfor a minimum of 0.25 secondsbefore the breaker was closed.Wait at least 0.25 seconds before closing the breaker afterremoving control power from the Shunt Trip.These instructions do not cover all details or variations in equipment nor do they provide for every possible contingency that may be met in connection with installation, operation, or maintenance.

西门子3WT断路器脱扣器整定说明

电子部件66.1过电流脱扣器 - 功能概述注意我们已经检查了本手册的内容以确保其与描述的硬件和软件一致。

但是也不能完全排除差异情况,因此我们不能担保此处所提供信息的正确性。

会定期检查本手册中的信息,并在以后版本中包括任何必要的修正。

过电流保护设置小心仅在断路器断开时调整参数。

如果在断路器接通的情况下修改参数,则可能会意外使断路器脱扣。

小心当规划项目和考虑选择性时,必须确保断路器上的负载不超过 3WT 产品目录中规定的分断能力。

就某种程度而言,必须设置上游保护设备才能安全地中断这些故障。

通过旋转编码开关调整所有参数。
