Locking device and method of use

Abstract

The invention relates to an insulating rod locking device. The insulating rod locking device comprises at least two insulating rods connected with each other, and is characterized in that at the connecting position of the insulating rods, one insulating rod is provided with a conical connecting sleeve, the other insulating rod is provided with a conical connecting rod in clearance fit with the conical connecting sleeve, the clearance fit is 0.2-0.8 mm, the inner end face of the connecting sleeve is at least quartered in the radial direction, correspondingly, the connecting rod is at least quartered in the radial direction, elastic bosses distributed irregularly are arranged at the quartered portions of the inner end face of the connecting sleeve and the connecting rod at intervals, and the height of the elastic bosses is 0.4-1.0 mm. Water, dirt and other impurities on the connecting sleeve or the connecting rod will be stored inside under extrusion of two conical surfaces, under embedding and extruding of the elastic bosses, conical matching surfaces are smoothly connected, and it can be avoided that due to poor cone matching, matching connecting performance is reduced. The insulating rod locking device has the advantages that machining is easy, connection between the insulating rods is reliable, connecting and detaching are convenient, working efficiency is improved, and working time is shortened.

Description

technical field [0001] The invention relates to a power supply tool of a power system, in particular to a locking device and a method for using the locking rods connected between the connecting rods during the power-off operation. Background technique [0002] We know that in order to better serve the society, the power system has established many power supply stations, which are responsible for the maintenance and repair of all power distribution equipment with a voltage level of 10kV and below within their jurisdiction. When stopping the 10kV drop-out fuse or the switch on the pole, it is operated with a gram rod. For the convenience of carrying, the current gram rod uses a combination of 4 sections, and the connecting parts are fastened with screws (bolts) About 3cm), the disadvantages of fastening with screws are that it is inconvenient to operate, and the second is that the force can only be applied up and down along the axis, which is not suitable for lateral radial fo...

Problems solved by technology

When stopping the 10kV drop-out fuse or the switch on the pole, it is operated with a gram rod. For the convenience of carrying, the current gram rod uses a combination of 4 sections, and the connecting parts are fastened with screws (bolts) About 3cm), the disadvantages of fastening with screws are that it is inconvenient to operate, and the second is that the force can only be applied up and down along the axis, which is not suitable for lateral radial force, which limits its scope of use. In addition, due to The connection part of the threaded rod is stuck due to debris such as sediment or uneven force, and the thread of the connecting part is stuck, which makes the connection difficult. If the rod cannot be connected quickly, it will affect the follow-up maintenance work , which is not conducive to the handling of work start and end procedures
