Description

一种接地开关及其相间联轴装置A grounding switch and its interphase coupling device

技术领域Technical field

本发明属于接地开关技术领域,具体涉及一种接地开关及其相间联轴装置。The invention belongs to the technical field of grounding switches, and specifically relates to a grounding switch and its interphase coupling device.

背景技术Background technique

三相接地开关用于保证整个回路接地安全,为保证接地效果,需要使地刀杆和静触头同步分合闸操作,这就对接地开关的同步传动及加工、传动精度提出更高要求。而且,接地开关在现场安装与调整过程中,需要反复进行三相分合操作,才能将产品调整到最佳使用状态,在调整过程中,需要反复拆装传动机构,并且,在运行过程中如果出现接地开关产品零件之间间隙造成分、合不到位,还需要通过解开传动链,重新调整,调整费时费力。The three-phase grounding switch is used to ensure the safety of the entire circuit grounding. In order to ensure the grounding effect, it is necessary to make the ground cutter bar and the static contact open and close synchronously. This puts forward higher requirements for the synchronous transmission, processing and transmission accuracy of the grounding switch. . Moreover, during the on-site installation and adjustment process of the grounding switch, repeated three-phase opening and closing operations are required to adjust the product to the optimal use state. During the adjustment process, the transmission mechanism needs to be repeatedly disassembled and assembled, and if during operation, If there is a gap between the parts of the grounding switch product, causing the components to not close properly, it is necessary to untie the transmission chain and readjust it, which is time-consuming and laborious.

在授权公告号为CN203013596U的中国实用新型专利中公开了一种安装位置可调的接地开关结构,包括相间连杆,相间连杆由通过抱箍固定连接在一起的子相间连杆构成,相间连杆由操动机构驱动转动,相间连杆通过抱箍抱紧固定三相动触头组件,在相间连杆转动时,驱动三相动触头组件与对应静触头组件分合闸操作。通过抱箍固定装配,使得接地开关为可拆式结构,调整时可松动抱箍,实现调整。上述接地开关中,动触头组件包括支撑板、铝导电压块、抱箍、铝管焊接触指支座及铜材触指,其中,铝导电块和支撑板一起通过螺栓夹紧铝管焊接触指支座,作为整体,再通过抱箍抱紧在相间连杆上。The Chinese utility model patent with the authorization announcement number CN203013596U discloses a grounding switch structure with adjustable installation position, including interphase connecting rods. The interphase connecting rods are composed of sub-interphase connecting rods fixedly connected together through hoops. The interphase connecting rods are The rod is driven to rotate by the operating mechanism, and the interphase connecting rod is tightly held and fixed by the hoop to fix the three-phase movable contact assembly. When the interphase connecting rod rotates, the three-phase movable contact assembly and the corresponding static contact assembly are driven to open and close operations. By fixing the assembly with the hoop, the grounding switch has a detachable structure, and the hoop can be loosened during adjustment to achieve adjustment. In the above grounding switch, the moving contact assembly includes a support plate, an aluminum conductive voltage block, a hoop, an aluminum tube welding contact finger support and a copper contact finger. Among them, the aluminum conductive block and the support plate are clamped together by bolts. The contact finger support, as a whole, is tightly held on the alternating connecting rods through the holding hoop.

上述接地开关中,子相间连杆之间通过抱箍固定连接形成相间连杆,再通过支撑板、抱箍等结构与动触头组件固定连接,子相间连杆的连接位置和动触头组件与相间连杆的连接位置错开,每处装配结构要么仅用于装配相间连杆,要么仅用于装配动触头组件,导致整个传动结构中的装配位置较多,容易积累装配误差,不利于保证装配精度。In the above-mentioned grounding switch, the sub-phase connecting rods are fixedly connected by clamps to form an interphase connecting rod, and then fixedly connected to the moving contact assembly by support plates, clamps and other structures. The connection positions of the sub-phase connecting rods and the connection positions of the moving contact assembly and the phase connecting rods are staggered. Each assembly structure is either only used to assemble the interphase connecting rods or only used to assemble the moving contact assembly, resulting in a large number of assembly positions in the entire transmission structure, which is prone to accumulate assembly errors and is not conducive to ensuring assembly accuracy.
