Detailed Description
The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.
A novel cable test protection device comprises an insulating sleeve, an insulating plugboard 5, a discharge polar plate 4 and a grounding wire 10, wherein the insulating plugboard is transversely inserted into the wall of the insulating sleeve, the insulating plugboard can be plugged and pulled, the discharge polar plate is fixedly arranged above the insulating plugboard in the insulating sleeve, the discharge polar plate is connected with the grounding wire, and the grounding wire penetrates out of a threading hole of the insulating sleeve and is connected with a grounding end wire clamp 11 at the tail end. The cable 7 is threaded from the bottom of the insulating sleeve. And a cable snap ring 8 is arranged at the lower part of the insulating sleeve, the cable penetrates through the center of the snap ring, and the cable snap ring is used for fixing the cable.
The insulating sleeve comprises a top cover 3, a sleeve body 6 and a bottom support 9 which are arranged from top to bottom, wherein the upper end and the lower end of the sleeve body are respectively provided with a threaded connecting part which is connected with the top cover and the bottom support through threads. The cable snap ring is coaxially arranged in the bottom support and made of hard plastic materials, so that the cable cannot be scratched.
A voice alarm 1 and a warning neon lamp 2 are installed in the top cover, the voice alarm and the warning neon lamp are both connected with an electromagnetic inductor, and the voice alarm and the warning neon lamp can be triggered after the electromagnetic inductor senses current.
The use method of the protection device comprises the following steps:
when the cable is tested, the test lead and the single-phase cable terminal are sealed in the insulating sleeve, the single-phase cable terminal and the test lead are directly connected with the metal electrode in the sleeve, and after pressurization, acousto-optic alarm is started to give a safety warning. After the test is finished, the insulating plate is pulled out by the insulating rod to discharge, and after the discharge is fully performed, the warning is eliminated. The tests were then performed sequentially.
The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, many modifications and improvements can be made without departing from the spirit of the present invention, and these modifications and improvements are all within the protection scope of the present invention.
