Problems solved by technology

[0002] For a long time, since the regional power grid feeders are equipped with low-cycle protection, when doing switch protection verification, sampling, and transmission, it is necessary to isolate the lines on and off the panel, especially the voltage lines. So far, there has been no change. Good way to ensure that isolated voltage lines are not shorted

Embodiment Construction

[0013] It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0014] Such as figure 1 As shown, the insulating sheath 1 according to the embodiment of the present invention includes a wire end sheath 11 and an extension sheath 12 . Thread end cover 11 is suitable with thread end. The extension sleeve 12 is connected with the wire end sleeve, and the extension sleeve 12 is used to prevent the wire end from protruding from the insulating sleeve 1 .

[0015] In this embodiment, the inner diameter of the thread end cover 11 is larger than the outer diameter of the thread end. Insulated wire end cover 11 prevents the exposed wire ends from short-circuiting. Preferably, the inner diameter of the extension sleeve 12 is smaller than the outer diameter of the ...

Abstract

The invention provides an insulating bush. The insulating bush comprises a wire end sleeve and an extending sleeve, wherein the wire end sleeve is used for adapting to a protected wire end; the extending sleeve is connected with the wire end sleeve; the extending sleeve is used for preventing the wire end from extending out of the insulating bush. By applying the technical scheme adopted by the invention, the probability of short circuit of the exposed wire end is reduced. Furthermore, the extending sleeve is in fit with a testing wire for connecting the wire end with a testing tool, so that convenience is provided for wiring of the tested wire end and testing efficiency is improved.

Description

technical field [0001] The invention relates to the field of electric power maintenance, and more specifically relates to an insulating sleeve. Background technique [0002] For a long time, since the regional power grid feeders are equipped with low-cycle protection, when doing switch protection verification, sampling, and transmission, it is necessary to isolate the lines on and off the panel, especially the voltage lines. So far, there has been no change. It is good practice to ensure that isolated voltage lines are not shorted. Contents of the invention [0003] The present invention aims to provide an insulating sheath that reduces the probability of short-circuiting of exposed wire ends. [0004] In order to achieve the above object, the present invention provides an insulating sleeve, which includes: a wire end sleeve adapted to the protected wire end; an extension sleeve connected with the wire end sleeve, and the extension sleeve is used to prevent the wire end f...
