Description
Technical Field
The utility model belongs to the electric power test equipment field specifically is an insulating sleeve composite member of frock for alternating current withstand voltage test.
Background
With the rapid development of social economy, electric power resources play an important role in our working life. While the electricity brings convenience to people, people should pay attention to electricity safety. At present, as the number of residential districts increases and the management is more standard, the safety of the power distribution room of the district is also highly concerned by power supply departments and property companies. The power equipment used in the power distribution room needs to be subjected to an electrical test before power transmission to ensure the reliability of the power equipment, the power distribution equipment in operation needs to be subjected to an electrical test in each overhaul period to check the integrity of the equipment, and one test in the electrical test is an alternating current withstand voltage test.
When carrying out the alternating current single-phase test, because the space of switch board leads to alternate safe distance not enough, adopt the guide bar to draw the back experiment with each looks of three-phase cable sleeve department in the high voltage distribution cabinet, the operating personnel touches the guide bar because of work negligence, will cause the personal potential safety hazard.
Disclosure of Invention
An object of the utility model is to overcome the above-mentioned not enough of prior art, and provide an insulating sleeve composite of frock for alternating current withstand voltage test, effectively solved the personal safety who has guaranteed testing personnel, reduce personal safety hidden danger.
The technical scheme of the utility model is that: insulating sleeve composite including the integrated into one piece structure, insulating sleeve composite includes insulating sleeve, insulating shed, pre-buried copper pipe fitting, shielding ground connection stud, the insulating sleeve inner chamber is the step, including the thick cylinder chamber that is located the afterbody, be located the thin cylinder chamber of front portion, the built-in pre-buried copper pipe fitting in thin cylinder chamber, pre-buried copper pipe fitting head stretches out in insulating sleeve's head, the insulating sleeve outer wall is the step, including the small circle post portion that is located the head, be located the big cylinder portion at middle part, be located the thick cylinder portion of afterbody, there is insulating shed on the big cylinder portion that is close to small circle post portion, shielding ground connection stud afterbody inlays in insulating sleeve outer wall middle part.
And the shielding grounding stud is connected with a bolt provided with a grounding wire.
The head of the embedded copper pipe fitting extends out of the head of the insulating sleeve by 20mm, the total length of the embedded copper pipe fitting is 400mm, and the total length of the insulating sleeve is 600mm.
And the thick cylindrical part and the large cylindrical part on the outer wall of the insulating sleeve are transited through the circular table top.
The insulating sleeve and the insulating umbrella skirt are integrally cast and molded by composite insulating silicon rubber materials.
The thick cylinder part corresponds to the thick cylinder cavity.
Due to the space problem of the high-voltage power distribution cabinet, the copper conducting rod is only required to be fixed in a cable sleeve of the high-voltage power distribution cabinet, and the insulating sleeve composite part sleeved outside the copper conducting rod is sleeved outside the cable sleeve through the tail thick cylindrical cavity, so that the insulating distance, the discharging distance and the creepage distance in the test can be met. When alternating current withstand voltage test is carried out, the personal safety of testing personnel is effectively guaranteed, and the working efficiency during the test is improved.
Insulating sleeve outer wall is the step shape, and the insulating sleeve outer wall passes through the effect of reducing design: firstly, dwindle insulating sleeve's clean distance has increased alternate air insulation clearance simultaneously, has secondly increased the creepage distance of copper guide arm to insulating full skirt, and the third is that the pre-buried copper pipe fitting of the fashioned in-process of pouring at insulating sleeve can be inseparabler with silica gel material laminating together, improves insulating sleeve's intensity, simultaneously in the use safe and reliable more.
Insulating full skirt plays and increases creepage distance among the insulation support, and the effect of increase air insulation distance, pre-buried copper pipe spare overall length 400mm plays the effect that increases the holistic intensity effect of insulation support and good electric conductivity, and 4mm are installed with M6 mm's bolt to shielding ground connection stud when the circular telegram test 2 The ground wire is used for safely grounding the leakage current during the test, and plays a role in protecting the equipment and a role in protecting the personal safety of testers and the test equipment.
