Embodiment 1

[0016] Embodiment 1: see figure 1 with figure 2 , The portable high-voltage grounding wire operating device includes a grounding clamp 1, an insulating rod 2 and an insulating handle 3, as well as a core rod 4 and a briquetting assembly 9 and other components. The insulating rod 2 and the grounding clamp 1 are fixed parts, and the insulating handle 3 and the core rod 4 are movable parts, which can drive the pressing plate assembly inside the grounding clamp 1 to move by rotating the movable part. The grounding clamp 1 adopts the aluminum grounding clamp 1, the insulating rod 2 adopts the glass fiber reinforced plastic insulating rod 2, and the insulating handle 3 adopts plastic. An upper insulating sleeve 14 and a lower insulating sleeve 15 are sleeved on the outside of the insulating rod 2 and the insulating handle 3 respectively, and an insulating ring 13 is sleeved on the upper side of the upper insulating sleeve 14 . Last insulating cover 14 adopts PVC handle, and lower...

Abstract

The invention discloses a portable high-voltage grounding line operating device, and the device comprises a grounding clamp, an insulating rod, and an insulating handle. The device also comprises a core rod and a press block assembly. The insulating rod and the insulating handle are in rotating connection. The core rod is disposed in a central axle hole of the insulating rod in a sleeved manner. The front end of the core rod is in butt joint with a press block, and the tail end of the core rod is provided with a threaded rod. An inner side of the insulating handle is provided with a threaded tube. The threaded rod at the tail end of the core rod is connected with the threaded tube in the handle. According to the device provided by the invention, an operating rod has a movable part and a fixed part, and the movable part and the fixed part can relatively rotate so as to enable an aluminum grounding clamp and an aluminum grounding clamping head to clamp a bus. There is no need of a frictional force between the grounding clamp and the bus for assisting the clamping. The operation is very convenient and safe, and a grounding device does not need to press the bus during operation, so there is no damage caused to the bus.

Description

Technical field: [0001] The invention belongs to the technical field of grounding tools for electric high-voltage lines, and in particular relates to a portable high-voltage grounding line operating device. Background technique: [0002] At present, the grounding clamp pressing head of the commonly used high-voltage grounding wire operating device is connected to the entire grounding wire operating rod. The movable part is the grounding clamp body. When using it, you can only hold the operating rod. The bus bar is a movable part. When the operating lever is rotated, the grounding clamp will rotate with the operating lever when the grounding clamp is not fixed by external force. However, when the grounding wire is connected, the bus bar is regarded as a charged body and cannot be fixed by hand. grounding clamp, so as to achieve the purpose of clamping; if you want to clamp, you need to rely on the friction between the grounding clamp and the busbar as a basis to rotate the gr...
