Description

一种抽屉式开关柜以及塑壳断路器、插接组件、装置 技术领域
本申请涉及一种抽屉式开关柜以及塑壳断路器、插接组件、装置。
背景技术
抽屉式开关柜是采用钢板制成封闭外壳，进出线回路的电器元件都安装在可抽出的抽屉中，抽屉式开关柜作为集中控制的配电中心，具有较高的可靠性、安全性和互换性，广泛应用于对供电可靠性要求较高的工矿企业和高层建筑中。
现有的抽屉式开关柜，如图27-29所示，包括柜体，以及可从柜体内抽出的抽屉，抽屉包括抽屉本体100，分设于抽屉本体100前后两侧的第一面板101和第二面板102，第一面板101上设有操作手柄103，第二面板102的左右两侧设有伸出抽屉本体100外、与进(出)线母排对应相连的转接器104，抽屉本体100的安装腔中部设置有塑壳断路器105，装配时，塑壳断路器105的断路器手柄106所在的操作面板108朝向第一面板101设置，塑壳断路器左右两侧的多个接线端子通过转接铜排107与对应的转接器104相连。上述方案的缺陷在于：1)由于断路器的长度方向和第一面板101的延伸方向相同，且要预留进出线两端转接铜排107接出的位置和爬电距离，这样会导致抽屉本体100的长度和宽度增大很多，从而大大增加了抽屉式开关柜的生产成本；2)配电房一般会配备有几台甚至几十台的抽屉式开关柜，而现有的抽屉式开关柜会占用很大的配电房的用地面积，使得配电房的建设成本大大增加；3)由于断路器的接线端子需要通过转接铜排107与转接器104相连，转接铜排107包括沿抽屉本体宽度方向(X轴方向)延伸的第一连接排109、沿抽屉本体长度方向(Y轴方向)延伸的第二连接排110、沿沿抽屉本体高度方向(Z轴方向)延伸的第三连接排111，第一连接排109、第二连接排110和第三连接排111为依次连接，转接铜排107长度较长，导致铜耗材量较大，不仅增加了生产成本，也增加了温升，且接线端子、第一连接排109、第二连接排110、第三连接排111和转接器104的相邻两个组件之间均通过螺栓固定连接，这样螺栓连接点较多，进一步抽屉本体内的温升。
塑壳断路器是断路器中的一种,其能够在电流超过跳脱设定后自动切断电流，具有过载长延时、短路瞬动等保护功能，还可以与漏电器、测量、电动操作机构等模块单元配合使用。
目前，塑壳断路器均采用螺栓连接的方式与转接铜排相连，而现有很多开关柜为带有快速插接功能的抽屉柜，抽屉柜的抽屉内安装有断路器，由于断路器采用螺栓紧固的安装方式与转接铜排相连，转接铜排再通过转接插头与抽屉外的接线母排相连，这样转接点较多，温升高，且装配繁琐，因此，急需申请一种适用于抽屉柜、可与接线母排实现快速插接的塑壳断路器。
发明内容
因此，本申请在于提出一种小型化、占地面积小、温升低、生产成本低的抽屉式开关柜以解决的技术问题在于克服现有技术中的抽屉式开关柜占地面积大、温升高、生产成本高的缺陷。本申请的另一目的在于提出一种装配快捷方便、用于抽屉柜内的接线母排快速插接的塑壳断路器、插接组件及装置以及克服现有技术中的塑壳断路器不能直接与抽屉柜内的母排实现快速插接、且转接点多、装配繁琐、散热效果差的缺陷。为此，本申请提供一种抽屉式开关柜以及塑壳断路器、插接组件、装置，有助于解决现有技术中存在的问题。本申请提供的一种抽屉式开关柜包括柜体，以及设于所述柜体内的抽屉，所述抽屉包括抽屉本体、塑壳断路器和插接组件，抽屉本体具有适于安装塑壳断路器的安装腔；塑壳断路器，包括断路器本体，以及设于所述断路器本体进线端一侧的多个第一导电件，所述断路器本体的长度延伸方向与所述抽屉的抽出方向相同；多个插接组件，设于所述断路器本体的进线端一侧，且伸出至所述抽屉本体外，所述插接组件与所述第一导电件相连，且适于与进线母排插接。

本申请的一种装置，包括如上所述的塑壳断路器，以及如上项所述的与塑壳断路器装配的插接组件。
本申请技术方案，具有如下优点：
1.本申请提供的抽屉式开关柜，由于断路器本体进线端的第一导电件直接与插接组件相连，插接组件伸出至抽屉本体外，并与进线母排插接，从而省去了现有技术中的铜排和转接器，这样不仅降低了铜排的成本，也降低了抽屉本体内的温升，且抽屉本体的长度会变短；另外，由于断路器本体按其长度方向与抽屉抽出方向相同的方向安装于抽屉本体内，这样大大缩小了抽屉和柜体的宽度，节约了用于制造抽屉和柜体的钣金材料，不仅降低了抽屉内的温升，也降低了生产成本，同时也大幅度的减少用于放置柜体的配电房的占地面积。
2.本申请提供的抽屉式开关柜，由于断路器本体的进线端伸出至抽屉本体外，这样一方面使得抽屉本体的长度可以进一步变短，降低了生产成本，另一方面降低了断路器本体和抽屉内的温升，提高了可靠性。
3.本申请提供的抽屉式开关柜，多个第一导电件沿断路器本体的宽度方向间隔分布，且第一导电件具有沿断路器本体高度方向延伸的第一连接板，以及与插接组件相连的第三连接板，这样大大缩短了断路器本体接线端与插接组件的接线长度，从而减小了铜排用量，降低了生产成本；另外，由于第一导电件和插接组件均安装于断路器本体宽度方向的侧板上，使得断路器本体的长度延伸方向能够与抽屉的抽出方向相同，从而大大缩小了抽屉和柜体的宽度，节约了用于制造抽屉和柜体的钣金材料，从而降低了生产成本。
4.本申请提供的抽屉式开关柜，断路器本体上设有适于在进线母排与插接组件插拔时、限定插接组件的第一限位结构，和/或，限定第一导电件位置的第二限位结构，由于进线母排的插拔力比较大，通过设置第一限位结构和第二限位结构，在进线母排插拔时，能够限定插接组件和第一导电件的位置，提高了插拔可靠性。
5.本申请提供的抽屉式开关柜，插接组件的边缘设有凸块，凸块适于在进线母排插入时、与第一面板相抵，从而避免因插接组件跟随进线母排同向移动而导致进线母排不能插入至插接组件的第一插槽内；第一面板远离凸块的一侧设有第一挡块，第一挡块适于在进线母排拔出时、与凸块相抵，从而避免因插接组件跟随进线母排同向移动而导致进线母排不易从第一插槽拔出；相互配合的凸块和第一挡块具有结构简单的优点。
6.本申请提供的抽屉式开关柜，第一挡块具有邻近其设置、可供凸块插入或穿出的第二开口，插接组件具有其凸块与第一挡块相抵的装配位置，以及凸块与第一挡块分离、可从第二开口穿出的拆卸位置。通过设置第二开口，从而有利于插接组件与断路器本体实现快速拆装。
7.本申请提供的抽屉式开关柜，通过在第一导电件的两侧设置第二挡块和第三挡块，从而对第一导电件的位置进行限定，由于第一导电件和插接组件固定，也即对插接组件的位置进行限定，这样进一步提高了插拔可靠性。
8.本申请提供的抽屉式开关柜，第一导电件的第一连接板、第二连接板、第三连接板和触头板为一体弯折成型，这样温升较低，且结构简单。
9.本申请提供的塑壳断路器，包括断路器本体和第一导电件，第一导电件适于通过插接组件与对应的母排插接，插接组件具有供母排弹性插入的第一插槽，由于断路器本体进线端的插接组件可直接与抽屉柜内的母排插接，这样不仅减少了转接铜排和转接插头，也减少了各组件之间的螺栓连接组件，从而降低了生产成本和温升；另外，第一插槽沿远离断路器本体的方向延伸，使得母排可以朝外延伸，增加了散热面积，这样散热效果更好，因此大幅度降低了断路器和抽屉柜的温升；此外，多个第一导电件沿断路器本体的宽度方向间隔分布，且第一连接板均沿断路器本体的高度方向延伸，这样第一导电件的铜材用量小，具有温升低、成本低的优点。
10.本申请提供的塑壳断路器，相邻两个所述第一导电件的两个第三连接板分别位于两个不同的竖直平面内，从而增加了相邻两个第三连接板以及相邻两个插接组件之间的爬电距离，提高了安全可靠性。
11.本申请提供的塑壳断路器，断路器本体上设有适于在母排与插接组件插拔时、限定插接组件的第一限位结构，和/或，限定第一导电件位置的第二限位结构，由于母排的插拔力比较大，通过设置第一限位结构和第二限位结构，在母排插拔时，能够限定插接组件和第一导电件的位置，提高了插拔可靠性。
12.本申请提供的塑壳断路器，插接组件的边缘设有凸块，凸块适于在母排插入时、与第一面板相抵，从而避免因插接组件跟随母排同向移动而导致母排不能插入至插接组件的第一插槽内；第一面板远离凸块的一侧设有第一挡块，第一挡块适于在母排拔出时、与凸块相抵，从而避免因插接组件跟随母排同向移动而导致母排不易从第一插槽拔出；相互配合的凸块和第一挡块具有结构简单的优点。
13.本申请提供的塑壳断路器，第一挡块具有邻近其设置、可供凸块插入或穿出的第二开口，插接组件具有其凸块与第一挡块相抵的装配位置，以及凸块与第一挡块分离、可从第二开口穿出的拆卸位置。通过设置第二开口，从而有利于插接组件与断路器本体实现快速拆装。
14.本申请提供的塑壳断路器，通过在第一导电件的两侧设置第二挡块和第三挡块，从而对第一导电件的位置进行限定，由于第一导电件和插接组件固定，也即对插接组件的位置进行限定，这样进一步提高了插拔可靠性。
