Description

一种隔离开关三相联动装置及隔离开关A three-phase linkage device of isolating switch and isolating switch 技术领域technical field
本发明属于隔离开关领域，具体涉及一种隔离开关三相联动装置及隔离开关。The invention belongs to the field of isolation switches, and in particular relates to a three-phase linkage device of an isolation switch and an isolation switch.
背景技术Background technique
220kV及以下的三相交流隔离开关普遍采用三相机械联动的方式实现一台操作机构同步驱动三相隔离开关分合闸。对于使用量极大的垂直断口隔离开关而言，由于三相隔离开关的排列角度多变，给三相之间的曲柄连杆传动造成了诸多麻烦。Three-phase AC isolation switches of 220kV and below generally use three-phase mechanical linkage to realize that one operating mechanism synchronously drives the three-phase isolation switch to open and close. For the vertical fracture isolating switch, which is widely used, due to the changeable arrangement angle of the three-phase isolating switch, a lot of troubles have been caused to the crank connecting rod transmission between the three phases.
为应对工程现场实际布置方式多变的情况，以往采用的方案主要为：1、采用针对工程布置需求的固定角度联动臂；2、采用无级可调的摩擦盘传动臂。采用针对工程布置需求的固定角度联动臂虽然传动连接可靠，但需要每次与工程布置角度对应匹配，需要花费大量的精力进行针对性设计制造，增加了很多沟通协调及管理成本，且容易出错，出错后现场整改十分不便，有时甚至需要更换隔离开关传动底座。而采用无级可调的摩擦盘传动臂方式虽然可以解决上述问题，但同时也带来了摩擦盘紧固不牢造成传动打滑的问题，增加了长期运行合闸传动不到位的安全风险，同时由于摩擦盘均是无级可调，安装调试时，现场定位初始角度十分不便，容易出错，给现场安装人员带来麻烦，因此以上两种以往的常规方案都存在不少缺点，无法两全。In order to cope with the changing situation of the actual layout of the project site, the main schemes adopted in the past are: 1. The fixed-angle linkage arm is adopted for the needs of the project layout; 2. The stepless adjustable friction disc transmission arm is adopted. Although the fixed-angle linkage arm for engineering layout requirements is reliable in transmission connection, it needs to be matched with the engineering layout angle every time. It takes a lot of energy to carry out targeted design and manufacture, which increases a lot of communication, coordination and management costs, and is prone to errors. On-site rectification is very inconvenient after errors, and sometimes even the isolation switch transmission base needs to be replaced. Although the stepless adjustable friction disc transmission arm method can solve the above problems, it also brings about the problem of transmission slippage caused by the friction disc is not fastened firmly, which increases the safety risk of insufficient closing transmission in long-term operation. Since the friction discs are infinitely adjustable, the initial angle of on-site positioning is very inconvenient during installation and debugging, which is prone to errors and brings trouble to the on-site installers. Therefore, the above two conventional solutions have many shortcomings and cannot achieve both.

参考图1至图6，旋转瓷瓶法兰100安装于隔离开关瓷瓶底座300上。旋转瓷瓶法兰100通过转轴200固定在隔离开关瓷瓶底座300上后，只能绕转轴200的轴线转动。旋转瓷瓶法兰100上设置了多个安装通孔110。联动调节机构400包括了输入端和输出端，联动调节机构400的输入端上设置有多个起始角度调节通孔410，联动调节机构400通过起始角度调节通孔410和安装通孔110连接到旋转瓷瓶法兰100的下表面。起始角度调节通孔410和安装通孔110的连接方式较多，可以直接采用螺栓螺母紧固件进行紧固，也可采用插销等方式进行紧固。三相隔离开关的每相都连接了一个联动调节机构400，多个联动调节机构400的输出端之间通过联动传动机构500连接到一起。Referring to FIGS. 1 to 6 , the rotating porcelain bottle flange 100 is installed on the disconnecting switch porcelain bottle base 300 . After the rotating porcelain bottle flange 100 is fixed on the isolation switch porcelain bottle base 300 through the rotating shaft 200 , it can only rotate around the axis of the rotating shaft 200 . A plurality of installation through holes 110 are provided on the rotating porcelain bottle flange 100 . The linkage adjustment mechanism 400 includes an input end and an output end. The input end of the linkage adjustment mechanism 400 is provided with a plurality of initial angle adjustment through holes 410 , and the linkage adjustment mechanism 400 is connected to the installation through hole 110 through the initial angle adjustment through holes 410 to the lower surface of the rotating porcelain bottle flange 100 . There are many connection modes between the starting angle adjustment through hole 410 and the installation through hole 110 , which can be directly fastened by bolts and nuts, or fastened by means of bolts and the like. Each phase of the three-phase isolation switch is connected with a linkage adjustment mechanism 400 , and the output ends of the multiple linkage adjustment mechanisms 400 are connected together through the linkage transmission mechanism 500 .
联动调节机构400的输入端的多个起始角度调节通孔410在和旋转瓷瓶法兰100上的多个安装通孔110进行安装时，可以通过改变起始角度调节通孔410和安装通孔110连接方式来改变输出端的输出角度。例如：假设起始角度调节通孔410有3个，编号1至3；安装通孔110有3个，编号1至3；第一连接时，可以让1号起始角度调节通孔410和1号安装通孔110连接，2号起始角度调节通孔410和2号安装通孔110连接，3号起始角度调节通孔410和3号安装通孔110连接；第二次连接时，可以让1号起始角度调节通孔410和2号安装通孔110连接，2号起始角度调节通孔410和3号安装通孔110连接，3号起始角度调节通孔410和1号安装通孔110连接，那么在联动调节机构400的输出端必定会发生一定角度旋转。When the plurality of initial angle adjustment through holes 410 at the input end of the linkage adjustment mechanism 400 are installed with the plurality of installation through holes 110 on the rotating porcelain bottle flange 100, the through holes 410 and the installation through holes 110 can be adjusted by changing the initial angle. Connection method to change the output angle of the output terminal. For example: Suppose there are three starting angle adjustment through holes 410, numbered 1 to 3; there are three mounting through holes 110, numbered 1 to 3; when the first connection is made, the starting angle adjustment through holes 410 and 1 of No. 1 can be The No. 1 installation through hole 110 is connected, the No. 2 starting angle adjustment through hole 410 is connected with the No. 2 installation through hole 110, and the No. 3 starting angle adjustment through hole 410 is connected with the No. 3 installation through hole 110; when connecting for the second time, you can Connect the No. 1 starting angle adjustment through hole 410 to the No. 2 installation through hole 110, connect the No. 2 starting angle adjustment through hole 410 to the No. 3 installation through hole 110, and connect the No. 3 starting angle adjustment through hole 410 to the No. 1 installation If the through hole 110 is connected, a certain angle rotation will surely occur at the output end of the linkage adjustment mechanism 400 .
通常三相隔离开关只有一相的转轴200下端连接隔离开关操作机构的垂直连杆，连接了隔离开关操作机构的这一相被称之为操作相。当操作相的旋转瓷瓶法兰100转动时，会通过联动传动机构500带动其它相同步运动。Usually, the lower end of the rotating shaft 200 of the three-phase isolating switch with only one phase is connected to the vertical link of the isolating switch operating mechanism, and the phase connected to the isolating switch operating mechanism is called the operating phase. When the rotating porcelain bottle flange 100 of the operating phase rotates, it will drive the other phases to move synchronously through the linkage transmission mechanism 500 .
此外，为了进一步提高联动调节机构400在旋转瓷瓶法兰100上安装的稳定性，通常会使起始角度调节通孔410和安装通孔110的孔径保持一致。In addition, in order to further improve the installation stability of the linkage adjustment mechanism 400 on the rotating porcelain bottle flange 100 , the diameters of the starting angle adjustment through hole 410 and the installation through hole 110 are usually kept the same.
根据本发明实施例的隔离开关三相联动装置，通过旋转瓷瓶法兰100上的多个安装通孔110和联动调节机构400上的多个起始角度调节通孔410可以保证联动调节机构400在旋转瓷瓶法兰100上进行稳固安装；同时，通过改变多个起始角度调节通孔410和多个安装通孔110对应连接关系，可以实现对联动调节机构400输出端的输出角度的有极调节。此外，通过将联动传动机构500连接与每一相联动调节机构400连接，可以实现多个联动调节机构400同步运动。According to the three-phase linkage device of the disconnector according to the embodiment of the present invention, through the plurality of installation through holes 110 on the flange 100 of the rotating porcelain bottle and the plurality of initial angle adjustment through holes 410 on the linkage adjustment mechanism 400, the linkage adjustment mechanism 400 can be ensured The rotating porcelain bottle flange 100 is stably installed; at the same time, by changing the corresponding connection relationship between the plurality of initial angle adjustment through holes 410 and the plurality of installation through holes 110, the output angle of the output end of the linkage adjustment mechanism 400 can be adjusted polarly. In addition, by connecting the interlocking transmission mechanism 500 with each phase interlocking adjusting mechanism 400 , a plurality of interlocking adjusting mechanisms 400 can move synchronously.
在本发明的一些实施例中，联动调节机构400包括：可调联动盘420、可调联动柄430。可调联动盘420，多个起始角度调节通孔410设置于可调联动盘420上；可调联动柄430，其具有连接端和调节端，连接端与可调联动盘420连接，调节端与联动传动机构500连接。可调联动盘420通过起始角度调节通孔410可以和旋转瓷瓶法兰100的下表面稳固连接，然后通过可调联动柄430可以和联动传动机构500连接。在本发明的一些实施例中，可调联动盘420在与可调联动柄430连接的部位延伸出了一个延长柄，通过延长柄可 以更好的完成与可调联动柄430的连接。通常在延长柄和可调联动柄430会同时开设多个对应且口径一致的通孔，然后可通过紧固件进行紧固连接。在本发明的一些实施例中，也可以爱用直接焊接等方式进行连接。在本发明的一些实施例中，在延长柄和可调联动柄430上开设的通孔数量有时候会比较多，这样可以实现延长柄和可调联动柄430连接长度的调节。In some embodiments of the present invention, the linkage adjustment mechanism 400 includes: an adjustable linkage disk 420 and an adjustable linkage handle 430 . The adjustable linkage plate 420, a plurality of starting angle adjustment through holes 410 are arranged on the adjustable linkage plate 420; the adjustable linkage handle 430 has a connection end and an adjustment end, the connection end is connected with the adjustable linkage plate 420, and the adjustment end It is connected with the linkage transmission mechanism 500 . The adjustable linkage plate 420 can be firmly connected to the lower surface of the rotating porcelain bottle flange 100 through the through hole 410 for adjusting the initial angle, and then can be connected to the linkage transmission mechanism 500 through the adjustable linkage handle 430 . In some embodiments of the present invention, the adjustable linkage plate 420 extends an extension handle at the position connected with the adjustable linkage handle 430, and the connection with the adjustable linkage handle 430 can be better completed through the extension handle. Usually, a plurality of corresponding through holes with the same diameter are opened in the extension handle and the adjustable linkage handle 430 at the same time, and then they can be fastened with fasteners. In some embodiments of the present invention, direct welding can also be used for connection. In some embodiments of the present invention, the number of through holes opened on the extension handle and the adjustable linkage handle 430 is sometimes larger, so that the connection length of the extension handle and the adjustable linkage handle 430 can be adjusted.
在本发明的一些实施例中，多个起始角度调节通孔410呈圆形分布。多个起始角度调节通孔410呈圆形分布呈圆形分布时，旋转瓷瓶法兰100上的安装通孔110也会对应呈圆形分布。在联动调节机构400需要改变输出角度时，圆形分布可以更加顺畅和方便的改变连接关系，实际操作时，只需要将联动调节机构400旋转到需要的角度并找到对应的安装通孔110进行紧固安装即可。In some embodiments of the present invention, the plurality of starting angle adjustment through holes 410 are distributed in a circle. When the plurality of starting angle adjustment through holes 410 are distributed in a circle, the installation through holes 110 on the rotating porcelain bottle flange 100 are also distributed in a circle correspondingly. When the linkage adjustment mechanism 400 needs to change the output angle, the circular distribution can change the connection relationship more smoothly and conveniently. In actual operation, it is only necessary to rotate the linkage adjustment mechanism 400 to the required angle and find the corresponding installation through hole 110 for tightening. Fixed installation.
在本发明的一些实施例中，每两个相邻的起始角度调节通孔410之间连线对应的圆心角相同。相应的，也需要旋转瓷瓶法兰100上的安装通孔110也对应呈圆形分布且圆心角相同。圆心角相同即意味着每两个相邻的起始角度调节通孔410之间的距离相同。在实际工程中，也意味着可以更为方便的确定旋转角度，只需要保证每两个相邻的起始角度调节通孔410之间连线对应的圆心角选择合适的值，则可以通过旋转至少一个圆心角的距离来调整联动调节机构400输出角度。In some embodiments of the present invention, the central angle corresponding to the connecting line between every two adjacent starting angle adjustment through holes 410 is the same. Correspondingly, it is also required that the installation through holes 110 on the flange 100 of the rotating porcelain bottle are also distributed in a circular shape and have the same central angle. The same central angle means that the distance between every two adjacent starting angle adjustment through holes 410 is the same. In practical engineering, it also means that the rotation angle can be determined more conveniently. It is only necessary to ensure that an appropriate value is selected for the central angle corresponding to the connection line between each two adjacent starting angle adjustment through holes 410, and then the rotation angle can be adjusted by rotating The distance of at least one central angle is used to adjust the output angle of the linkage adjustment mechanism 400 .
在本发明的一些实施例中，每两个相邻的起始角度调节通孔410之间连线对应的圆心角为45度。参考图2、图4、图6，在实际工程中，垂直断口隔离开关常用标准布置方式有45度布置、135度布置 及一列式布置三种，布置角度皆为每档45度；由于每相隔离开关从分闸到合闸旋转的角度为135度，且为使分合闸状态下联动调节机构400与联动传动机构500的夹角一致，因此分和闸状态下联动调节机构400与联动传动机构500的夹角均保证为22.5度，保证为22.5度还可以避免联动传动机构500与隔离开关旋转瓷瓶法兰100距离太近，进而导致干涉或进入传动死角而无法传动。由于每两个相邻的起始角度调节通孔410之间连线对应的圆心角为45度，因此可以推算出起始角度调节通孔410的个数为8个，8个始角度调节通孔可以每间隔1孔与旋转瓷瓶法兰100上4个孔对齐连接，每跳转1孔可使联动调节机构400的输出角度变更45度，因此可以在不变更任何零部件的情况下，根据布置角度的变换，直接变更安装孔方向。In some embodiments of the present invention, the central angle corresponding to the connecting line between every two adjacent starting angle adjustment through holes 410 is 45 degrees. Referring to Figure 2, Figure 4, and Figure 6, in actual engineering, the commonly used standard layouts of vertical fracture isolation switches include 45-degree layout, 135-degree layout and one-line layout, and the layout angles are all 45 degrees per gear; The rotation angle of the isolation switch from opening to closing is 135 degrees, and in order to make the angle between the linkage adjustment mechanism 400 and the linkage transmission mechanism 500 consistent in the opening and closing state, the linkage adjustment mechanism 400 and the linkage transmission in the opening and closing state are consistent. The included angle of the mechanism 500 is guaranteed to be 22.5 degrees, and the guaranteed 22.5 degrees can also prevent the linkage transmission mechanism 500 from being too close to the isolation switch rotating porcelain bottle flange 100, thereby causing interference or entering the dead angle of the transmission and failing to transmit. Since the central angle corresponding to the connecting line between every two adjacent starting angle adjustment through holes 410 is 45 degrees, it can be deduced that the number of starting angle adjustment through holes 410 is 8, and the eight starting angle adjustment through holes 410 are The holes can be aligned with the four holes on the rotating porcelain bottle flange 100 at intervals of one hole, and the output angle of the linkage adjustment mechanism 400 can be changed by 45 degrees every time the hole is skipped. Changing the layout angle directly changes the direction of the mounting holes.
在本发明的一些实施例中，调节端设置有多个跳转角度调节通孔431，每个跳转角度调节通孔431皆可单独实现与联动传动机构500的连接。参考图3、图5，对于非一列式布置的情况，除了标准的45度布置、135度布置之外，工程实际情况中还存在数量众多的既不是标准的45度布置，也不是标准的135度布置，由于垂直断口隔离开关一般安装于母线下方，且下层出线与上层母线垂直，由于上层母线与下层出线的相间距离一般不会完全相同，导致实际布置角度经常与标准的45度布置、135度布置存在一定的偏差，常见偏差中，最大偏差角度在10度，对于常用135度传动的隔离开关而言，10度偏差将导致联动调节机构400在合闸或分闸时与联动传动机构500的夹角过小或过大，进而出现干涉问题，甚至无法正常传动。参考图3，当布置角度偏差导致分闸状态下三相联动臂与三相连线夹角 变大超过2.5度以上时，可通过调整联动传动机构500与调节端不同跳转角度调节通孔431的连接使夹角尽可能接近22.5度，从而消除因布置角度偏差带来的影响，且只需直接换孔，无需逐相微调，从而极大的方便了现场安装调试工作。同样，参考图5，则是将联动传动机构500往远离旋转瓷瓶法兰100的方向调整，同样使夹角尽可能接近22.5度。In some embodiments of the present invention, the adjustment end is provided with a plurality of jump angle adjustment through holes 431 , and each jump angle adjustment through hole 431 can be independently connected to the linkage transmission mechanism 500 . Referring to Figure 3 and Figure 5, for the non-in-line layout, in addition to the standard 45-degree and 135-degree layouts, there are also a large number of non-standard 45-degree layouts and 135-degree layouts in actual engineering situations. Since the vertical fracture disconnector is generally installed below the busbar, and the lower outlet is perpendicular to the upper busbar, because the phase-to-phase distance between the upper busbar and the lower outlet is generally not exactly the same, the actual arrangement angle is often the same as the standard 45-degree arrangement, 135° There is a certain deviation in the degree arrangement. Among the common deviations, the maximum deviation angle is 10 degrees. For a common isolation switch with 135-degree transmission, a 10-degree deviation will cause the linkage adjustment mechanism 400 to interact with the linkage transmission mechanism 500 when closing or opening. If the included angle is too small or too large, there will be interference problems, and even normal transmission will not be possible. Referring to Fig. 3, when the deviation of the arrangement angle causes the angle between the three-phase linkage arm and the three-phase line to increase by more than 2.5 degrees in the open state, the through hole 431 can be adjusted by adjusting the linkage transmission mechanism 500 and the different jumping angle of the adjusting end. The connection makes the included angle as close to 22.5 degrees as possible, so as to eliminate the influence caused by the deviation of the layout angle, and only need to change the hole directly, without the need for phase-by-phase fine-tuning, which greatly facilitates the on-site installation and debugging work. Similarly, referring to FIG. 5 , the linkage transmission mechanism 500 is adjusted in a direction away from the flange 100 of the rotating porcelain bottle, and the included angle is also as close to 22.5 degrees as possible.
在本发明的一些实施例中，多个跳转角度调节通孔431呈圆弧形分布。呈圆弧形分布可以降低联动传动机构500与调节端连接的难度，当所有跳转角度调节通孔431皆以可调联动盘420的旋转中心为圆心时，则可以保证每更换一个跳转角度调节通孔431，都可以保证可调联动盘420的旋转中心到跳转角度调节通孔431的距离不变，进而可以保证只要联动传动机构500开设唯一的通孔即可完成与所有跳转角度调节通孔431的配套。而如果多个跳转角度调节通孔431并没有呈圆弧形分布，则需要在联动传动机构500上开设多个通孔，或者根据所有跳转角度调节通孔431的布置在联动传动机构500上开设一个异型的通孔以保证能与所有跳转角度调节通孔431配对。In some embodiments of the present invention, the plurality of jump angle adjustment through holes 431 are distributed in a circular arc shape. The arc-shaped distribution can reduce the difficulty of connecting the linkage transmission mechanism 500 with the adjustment end. When all the jump angle adjustment through holes 431 are centered on the rotation center of the adjustable linkage plate 420, it can be guaranteed that each jump angle is replaced. Adjusting the through hole 431 can ensure that the distance from the center of rotation of the adjustable linkage plate 420 to the jump angle adjustment through hole 431 remains unchanged, thereby ensuring that as long as the linkage transmission mechanism 500 opens a unique through hole, all the jump angles can be connected with each other. Adjust the matching of the through holes 431 . However, if the plurality of jump angle adjustment through holes 431 are not distributed in an arc shape, it is necessary to open a plurality of through holes in the linkage transmission mechanism 500, or according to the arrangement of all the jump angle adjustment through holes 431 in the linkage transmission mechanism 500 A special-shaped through hole is opened on it to ensure that it can be matched with all the jump angle adjustment through holes 431 .
在本发明的一些实施例中，每两个相邻的跳转角度调节通孔431之间连线对应的圆心角相同。这样可以保证每次调整跳转角度调节通孔431时能够准确的把握调整的角度，而不需要再使用专业工装进行角度测量。In some embodiments of the present invention, the central angle corresponding to the connecting line between every two adjacent jump angle adjustment through holes 431 is the same. In this way, it can be ensured that the adjusted angle can be accurately grasped each time the jump angle adjustment through hole 431 is adjusted, and there is no need to use professional tooling to measure the angle.
在本发明的一些实施例中，每两个相邻的跳转角度调节通孔431之间连线对应的圆心角为5度。以跳转角度调节通孔431数量5个 为例，跳转角度调节通孔431数量5个则具备4个间距，每个间距可以可通过设定完成5度的调整，实际可完成对联动调节机构400和联动传动机构5002.5度的调整，最大调整的范围则可以保证有10度。此外可以通过增设跳转角度调节通孔431的数量来使调整的范围变大。或者减小每两个相邻的跳转角度调节通孔431之间连线对应的圆心角来提高调整的精度。In some embodiments of the present invention, the central angle corresponding to the connecting line between every two adjacent jump angle adjustment through holes 431 is 5 degrees. Taking the number of jump angle adjustment through holes 431 as an example, there are 5 jump angle adjustment through holes 431 with 4 spacings, and each spacing can be adjusted by 5 degrees by setting, and the linkage adjustment can actually be completed. The adjustment of the mechanism 400 and the linkage transmission mechanism 5000 is 2.5 degrees, and the maximum adjustment range can be guaranteed to be 10 degrees. In addition, the adjustment range can be enlarged by increasing the number of the jump angle adjustment through holes 431 . Alternatively, the central angle corresponding to the connection line between every two adjacent jump angle adjustment through holes 431 can be reduced to improve the adjustment accuracy.
在本发明的一些实施例中，联动传动机构500包括：多个联动连杆510、多个连接部件520。多个联动连杆510，用于使多个联动调节机构400进行同步运动；多个连接部件520，同时与联动调节机构400和联动连杆510连接。多个联动连杆510用于实现不同相之间的联动调节机构400的连接，对于三相隔离开关而言，则设置两根联动连杆510即可完成传动和联动。连接部件520可以将联动连杆510的末端与联动调节机构400的输出端连接到一起。In some embodiments of the present invention, the linkage transmission mechanism 500 includes: a plurality of linkage links 510 and a plurality of connecting parts 520 . The plurality of linkage links 510 are used for synchronizing movement of the plurality of linkage adjustment mechanisms 400 ; The multiple linkage links 510 are used to realize the connection of the linkage adjustment mechanism 400 between different phases. For a three-phase isolation switch, the transmission and linkage can be completed by setting two linkage links 510 . The connection part 520 can connect the end of the linkage link 510 and the output end of the linkage adjustment mechanism 400 together.
在本发明的一些实施例中，连接部件520采用了连接销来连接联动调节机构400和联动连杆510。通常在联动连杆510的末端位置会开设通孔，配套的在联动调节机构400的输出端也会设置通孔，然后将通过连接销将联动调节机构400和联动连杆510连接到一起。在本发明的一些实施例中，也可以直接采用螺栓紧固件进行紧固，但是相对于连接销而言，稳固程度会差一些。In some embodiments of the present invention, the connecting member 520 adopts a connecting pin to connect the linkage adjusting mechanism 400 and the linkage link 510 . Usually, a through hole is provided at the end of the linkage link 510 , and a through hole is also provided at the output end of the linkage adjustment mechanism 400 , and the linkage adjustment mechanism 400 and the linkage linkage 510 are connected together by connecting pins. In some embodiments of the present invention, bolt fasteners can also be directly used for fastening, but the degree of stability will be less than that of connecting pins.
