But the shortcoming of this existing insulation rod detachable hanging hook device is as follows:
One, this kind of hook is only applicable to hang cylindrical pressure device, and the size radius of detachable device is fixed, and can not change.
Its two, part is more, be not easy to management, part is easily lost.
Its three, for applicable frequency response method measuring transformer winding deformation, this device can not reliable contacts cannula end.
Its four, the length of insulation rod can only lean on insulating bar joint number to adjust, and can not finely tune.
Utility model content
For overcoming the defect existed in above-mentioned prior art, the utility model provides a kind of telescopic high voltage insulating bar.Its objective is and provide one can save the activity duration in a large number, work efficiency is significantly improved, and flexible and convenient operation, the significant a kind of extension type High-Voltage Insulation bar of security performance.
For achieving the above object, the technical scheme that the utility model adopts is:
A kind of telescopic high voltage insulating bar, comprises insulation rod, stainless steel clip, direct current generator battery and fine rule; Described insulation rod is nested together by two insulation rods and forms, every single built-in electrical insulation rod and exterior insulation rod are all that the insulation rod with hollow structure reduced successively by three sections of diameters is formed, wherein one end inner portion of each section of exterior insulation rod is connected with a fixing annulus, first section of exterior insulation rod is respectively equipped with a direct current generator with rear, the axle of direct current generator is wound around fine rule, fine rule through the annulus inside exterior insulation rod, and encloses around one on annulus; Stainless steel clip is arranged at the end of insulation rod, and wherein a fan of clip is connected with exterior insulation rod, and another fan of clip is connected with built-in electrical insulation rod.
The inside of described exterior insulation rod is hollow, and the inside of built-in electrical insulation rod is also hollow, and the length of built-in electrical insulation rod will be longer than exterior insulation rod.
Described direct current generator, direct current generator rotates and drives fine rule motion, because fine rule has friction force with annulus at the volley, therefore drives insulation rod elongated; Because exterior insulation rod is connected by stainless steel clip with the end of built-in electrical insulation rod, in the process of therefore extending at outside insulation rod, built-in electrical insulation rod is and then elongation also; After finishing the work, then crawl direct current generator is according to reverse direction operation, and the length of insulation rod shortens gradually.
Advantage of the present utility model and effect are:
The utility model clamps cannula end line bank owing to using clip, electric expansion rod is used to reduce the volume of insulation rod, therefore can realize hanging test copper cash to be connected with reliable between cannula end line bank, preferably resolve problems of the prior art.The utility model device is applicable to the size characteristics of cannula end outlet row, and can reliable contacts, and eliminate artificial climbing and raise engineering truck, its parts of the utility model is less, and it is more convenient to use, is also convenient to manage simultaneously.Also there is structure simple, easy and simple to handle, variable volume, portable distinguishing feature.The scalable control of the length of insulation rod in the utility model in addition, trickle adjustment.Comparatively prior art have use flexibly, distinguishing feature easily, and due to effective utilization of scalable insulation rod, also substantially increase the Personal Safety of operating personnel, the activity duration can be saved in a large number, work efficiency is significantly improved.
The problem that the telescopic high voltage insulating device of the utility model design mainly solves is, when carrying out deformation of transformer winding test, conveniently on bushing shell for transformer end hangs, test copper cash, reduce the number of times of artificial climbing transformer and rising engineering truck, increase work efficiency, more convenient to carry, and this device applicable can connect more reliably, adds the credibility of data.
Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.
