Description
Technical Field
The utility model relates to a power equipment's technical field especially relates to an adjustable angle formula G type wire clamp anchor clamps of earth potential live working.
Background
Because the line camber of G shape fastener is great, simple structure and ingenious, therefore under the intermediate potential operating condition, the operating personnel who is located on insulating bucket arm car and other insulating ascending vehicle or platforms can use the G shape fastener overlap joint drainage line on the main circuit very smoothly, accomplish the maintenance task of not cutting off the power supply.
In many cases, an insulated arm car in a mountain area cannot reach a work site, or the terrain and wiring conditions of the work site are not suitable for live working at an intermediate potential. In this case, the maintainers can only adopt the ground potential live working method to carry out maintenance work. The ground potential live working method is a non-power-outage maintenance operation which is carried out by means of manual ascending and adopting an insulating rod operation method, and in the live working of a 10kV distribution network, the maximum moving range of a human body must be 0.4m away from a charged body, and the effective insulation length of an insulating operating rod is not less than 0.7 m. In the case where such an operator cannot directly contact the electrified body through the insulating glove, it is difficult for the operator on the pole to mount the G-clamp to the main line-to-line by means of the existing tool.
Since the operator must not cross the live line in order to ensure safety when conducting live work under earth-working potential conditions, the operator must always be located under the main line and the fuse cross arm or pole top switch bracket and maintain a sufficient safety distance. In the whole operation process, most of the personnel on the rod are in the upward-looking posture in the operation process. Therefore, the G-shaped clamp lock must securely fix the clamp, and the tail of the fastening bolt must face downward or at a proper angle thereof in order for the worker on the pole to perform the work of fastening the screw using the insulated operating rod.
When the traditional insulating operating rod is adopted to carry out the work of lapping the drainage wire in an electrified way, an electrician on the rod must use one hand to upwards prop the drainage wire against the upper piece of the wire clamp through the insulating locking rod, so that the drainage wire is prevented from being separated from the groove of the wire clamp. And the other hand pulls the wire clamp lock downwards to firmly buckle the wire clamp lock on the main line conductor. The operation method is simple in principle, but the physical consumption of operators on the pole is huge, and the overhauling quality can be different along with the operation process level of the operators and the different operation field environments. And the traditional lapping method has certain limitation in the application range. Therefore, it is urgently needed to design a novel wire clamp lock, so that the functions of the traditional insulating lock rod and the wire clamp lock are organically combined together, and the drainage wire can be reliably fixed in a wire clamp groove while the wire clamp is fixed.
When the branch leads of the distribution network 10kV line are in live lapping connection under the ground potential working condition, when the included angle between the tangential direction of the main line lead at the lapping point and the horizontal line exceeds +/-5 degrees or the distance between the lapping point and the cross arm exceeds 1.3 meters, the operator on the rod can not use the conventional horizontal fixed wire clamp lock to install the wire clamp in place. Therefore, there is a need to develop an angle-adjustable G-type wire clamp for earth potential live working to solve the problems in the prior art.
