Description

一种用于集节式接地电气设备的接地集节 技术领域
本发明涉及属于避雷的技术领域，具体涉及一种用于集节式接地电气设备的接地集节。
背景技术
输电线路的接地装置是维护电气设备安全可靠运行、保障电气设备与运行人员安全的基本保障和重要措施，接地装置包括接地体和接地线，而具有良好冲击特性的接地体可通过将闪电电流导入地下起到防雷的作用，为输电线路提供有效的防护，从而避免因为雷击引发停电事故，对电气设备的安全运行以及供电可靠性均具有十分重要的意义。
现有的接地集节在与接地导体安装连接时，由于接地集节体积比接地导体大在安装施工中开挖面积较大，不利于环保；另外，接地集节无法适应不同尺寸的接地导体，接地集节的通用性较差。
发明内容
针对现有技术存在的不足，本发明的目的在于提供一种用于集节式接地电气设备的接地集节，具有减少开挖面积的优点，且提高接地集节的通用性。
为实现上述目的，本发明提供了如下技术方案：
一种用于集节式接地电气设备的接地集节，包括有若干相互配合设置的集节单体，每一所述集节单体的外侧面均开设有弧形凹面，所述弧形凹面开设有滑槽，所述滑槽的内部滑动连接有弹性件，所述弹性件的两端分别连接有滑块，所述滑块滑动连接于所述滑槽的内部，所述滑块均活动连接有用于与接地导体配合的弧形固定件，所述弧形固定件采用可适应不同尺寸接地导体的导电材料制成；所述集节单体之间连接有锁紧装置。
通过采用上述技术方案，集节单体之间连接有锁紧装置，进而将若干集节单体连接为一接地集节整体，通过锁紧装置实现对集节单体的安装于拆卸，使得接地集节实现分体，便于用户对接地集节的运输以及安装，且在安装时由于集节单体的体积小于整体接地集节的体积，从而便于集节单体下土更为方便，减少土地的开挖面积，进而降低工作人员的开挖工作量。通过在滑块均活动连接有用于与接地导体配合的弧形固定件，当若干集节单体通过锁紧装置夹在接地导体的外部时，随着锁紧装置的收紧弧形固定件与接地导体相互挤压，进而导致弧形固定件逐渐形变，滑块以及弹性件同时跟随移动，起到调整弧形固定件位置的作用，使得弧形固定件与接地导体更为紧密贴合；同时，由于弧形固定件与滑块之间滑动连接，进而提高弧形固定件的灵活性，使得弧形固定件能够适应不同尺寸的接地导体，提高了接地集节的通用性。通过采用可适应不同尺寸接地导体的导电材料制成，使得接地导体的电荷能够传递至集节单体；同时，使得弧形固定件的弧度能够较易改变，使得弧形固定件能够适应不同尺寸的接地导体。
本发明进一步设置为：所述滑槽开设于所述弧形凹面的中间位置，所述滑槽与所述弧形凹面之间平行设置。
通过采用上述技术方案，滑槽开设于弧形凹面的中间位置，使得集节单体的受力的更为均匀，进而提高弧形固定件与接地导体连接的牢靠性，且滑槽与弧形凹面之间平行设置，当集节单体安装时，使得若干弧形固定件之间均位于同一水平面上，使得弧形固定件对接地导体的夹持更为稳固，提高了接地集节的可靠性。
本发明进一步设置为：当所述集节单体处于安装时，所述滑槽在水平方向的投影长度与所述弧形凹面的投影长度相同设置。
通过采用上述技术方案，增大滑块的行程范围，提高集节单体的灵活性，进 而提高接地集节的适应能力。
本发明进一步设置为：所述滑槽的中部位置设置有用于固定所述弹性件的弹性固定片。
通过采用上述技术方案，减少弹性件脱离滑槽的状况发生，提高了接地集节的稳定性。
本发明进一步设置为：所述滑槽的两端固定连接有用于限制所述滑槽滑动的挡板。
通过采用上述技术方案，避免滑块脱离滑槽，确保滑块沿滑槽滑动，提高了滑块运动的稳定性。
本发明进一步设置为：所述锁紧装置包括贯穿于所述集节单体两端的穿孔，相邻的所述集节单体之间通过锁紧螺栓穿过所述穿孔连接。
通过采用上述技术方案，进而将若干集节单体连接为一接地集节整体，通过锁紧装置实现对集节单体的安装于拆卸，使得接地集节实现分体，便于用户对接地集节的运输以及安装，且在安装时由于集节单体的体积小于整体接地集节的体积，从而便于集节单体下土更为方便，减少土地的开挖面积，进而降低工作人员的开挖工作量。
本发明进一步设置为：弧形固定件采用弹簧钢制成。
通过采用上述技术方案，弹簧钢的特点是在动载荷下工作,即在冲击、振动的条件下,或在交变应力作用下工作，具有足够的韧性和塑性,以防止在压力作用下突然脆断，提高接地集节的可靠性。
综上所述，本发明具有以下有益效果：
1.通过集节单体之间连接有锁紧装置，进而将若干集节单体连接为一接地 集节整体，通过锁紧装置实现对集节单体的安装于拆卸，使得接地集节实现分体，便于用户对接地集节的运输以及安装，且在安装时由于集节单体的体积小于整体接地集节的体积，从而便于集节单体下土更为方便，减少土地的开挖面积，进而降低工作人员的开挖工作量；
2.通过在滑块均活动连接有用于与接地导体配合的弧形固定件，当若干集节单体通过锁紧装置夹在接地导体的外部时，随着锁紧装置的收紧弧形固定件与接地导体相互挤压，进而导致弧形固定件逐渐形变，滑块以及弹性件同时跟随移动，起到调整弧形固定件位置的作用，使得弧形固定件与接地导体更为紧密贴合；同时，由于弧形固定件与滑块之间滑动连接，进而提高弧形固定件的灵活性，使得弧形固定件能够适应不同尺寸的接地导体，提高了接地集节的通用性。

具体实施方式
以下结合附图及实施例，对本发明作进一步详细说明。
如图1至图2所示，本发明公开的一种用于集节式接地电气设备的接地集节，包括有两组相互配合设置的集节单体1，两组集节单体1之间安装有起到连接作用的锁紧装置6，锁紧装置6包括贯穿于集节单体1两端的穿孔5，两组集节单 体1之间通过锁紧螺栓穿过穿孔5固定连接；每一集节单体1的外侧面均开设有弧形凹面2，弧形凹面2开设有滑槽3，滑槽3的内部滑动连接有弹性件31，弹性件31采用为压缩弹簧。如图3和图4所示，弹性件31的两端分别固定连接有滑块32，滑块32滑动连接于滑槽3的内部，滑块32的外侧面均铰接有用于与接地导体配合的弧形固定件4。
如图2和图4所示，滑槽3的横截面形状为“T”形，滑槽3开设于弧形凹面2的中间位置，滑槽3与弧形凹面2之间平行设置。当集节单体1处于安装时，滑槽3在水平方向的投影长度与弧形凹面2的投影长度相同设置，滑槽3在竖直方向的投影长度与弧形固定件4在竖直方向的投影宽度相同设置。
弧形固定件4采用具有导电性能的弹簧钢制成，弧形固定件4的厚度为2-4mm，弧形固定件4的弧口朝向远离滑块32的一端。
滑槽3的中部位置固定连接有用于固定弹性件31的弹性固定片33。滑槽3的两端固定连接有用于限制滑槽3滑动的挡板34。
本实施例的工况及原理如下：
在使用该用于集节式接地体的接地集节时，将两个集节单体1夹在接地导体的外部，通过将锁紧螺栓穿过穿孔5，并逐渐让锁紧螺栓将两组集节单体1锁紧，在锁紧的过程中弧形固定件4受到接地导体的挤压力而变形，弧形固定件4渐渐张开，将接地导体卡住，滑块32随之滑动以及弹性件31被压缩，使得弧形固定件4与接地导体能够更大面积贴合接触，弹性件31受到挤压，并提供给滑块32一个反作用力，使弧形固定件4与接地导体紧密贴合，弧形固定件4和滑块32均为导体，将接地导体上的电荷传递给集节单体1。该接地集节为分体式，在运输以及安装时较方便，在安装时由于集节单体1与整个接地集节相比体积较小， 下土安装时较方便，减少开挖面积；同时，提高弧形固定件4的灵活性，使得弧形固定件4能够适应不同尺寸的接地导体，提高了接地集节的通用性。
上述实施例只是为了说明本发明的技术构思及特点，其目的是在于让本领域内的普通技术人员能够了解本发明的内容并据以实施，并不能以此限制本发明的保护范围。凡是根据本发明内容的实质所做出的等效的变化或修饰，都应涵盖在本发明的保护范围内。
