Abstract
The utility model discloses a thermosensitive color-changing insulating cover and relates to a high-voltage insulation protective device in a power distribution network. The thermosensitive color-changing insulating cover comprises a contact (0) which needs insulation in electrical equipment and is provided with an insulating rubber lining layer (1) and a thermosensitive color-changing insulating rubber layer (2), the thermosensitive color-changing insulating rubber layer (2) is composited outside the insulating rubber lining layer (1), and the thermosensitive color-changing insulating protective cover is arranged outside the contact (0) which needs insulation in the electrical equipment. The utility model is applied to the insulation modification of the power distribution network, not only can insulate and protect the contact in the electrical equipment, but also can warn the fault condition of the equipment in advance and prevent the accidents through the color-changing function.
Description
Technical field
The utility model relates to a kind of High-Voltage Insulation protective device in the distribution network, relates in particular to a kind of thermosensitive colour-changing insulated cover.
Background technology
Nearly two during the last ten years, and the urban power distribution network insulating is transformed, and has solved tree line contradiction, the narrow contradiction in circuit corridor, resident compact district effectively and has weighed down thing contradiction in the air, has significantly improved urban power distribution network safe operation reliability.But, still there is a large amount of insulation blank spots in the urban power distribution network, as: lightning arrester, fuse, disconnecting link or switch, circuit prop up and connect, transformer pile crown and cable rod rising device etc. need electric overlapping part; And owing to be subjected to weighing down thing, toy and branch touching in the air, or since be subjected to workmen's false touch and and the false touch of resident living apparatus and etc. unexpected factor remain and cause the be short-circuited one of the main reasons of fault and the person, equipment breakdown of distribution network, and rate of failure is in rising trend.
In order to eliminate distribution network insulation blank spot, adopt insulating material that electric overlapping part is carried out supplementary insulation usually, obtained certain effect.Because these supplementary insulations block line inspection personnel sight line, and the defective of the electric overlapping part of circuit, as metallic conductor bolted power in the lapping construction process make the conductor contact resistance increase inadequately or running in after the oxidation of bonding conductor contact-making surface contact resistance increase, cause defectives such as contact site local overheating, and the type defective is difficult in time be found by tour personnel and maintainer, finally causes the circuit operation troubles; Even quicken conductor contact site electrochemical corrosion, cause the short-term accident.A lot of similar accidents have taken place in many urban power distribution network, south, seriously threaten the person, device security.Avoid accident to produce so press for a kind of method of this type of fault of can intuitively finding.
Now both at home and abroad research and production unit have been developed some thermosensitive chromotropic materials, and successful Application arrives in the middle of some products, the marker color of these products or appearance color can be varied with temperature and change.
Summary of the invention
The purpose of this utility model is to utilize the temperature of thermosensitive chromotropic material to become characteristic, and a kind of thermosensitive colour-changing insulated cover is provided.
The purpose of this utility model is achieved in that
Comprise the contact in the electric equipment of needs insulation, be provided with electro-insulating rubber inner covering and thermosensitive colour-changing insulated rubber layer;
At the thermosensitive colour-changing insulated rubber layer of the compound one deck in the outside of electro-insulating rubber inner covering; This thermosensitive colour-changing insulated cover is installed in the outside of the contact in the electric equipment of needs insulation.
Operation principle of the present utility model is:
The utility model is installed in electric overlapping part in the distribution network.If these electric overlapping parts exist as metallic conductor bolted power in the lapping construction process when making in increase of conductor contact resistance or the running after the oxidation of bonding conductor contact-making surface defective such as contact resistance increase inadequately, be in operation and the heating phenomenon to occur, its temperature can make thermosensitive colour-changing insulated rubber layer generation obvious color change, make things convenient for timely, convenient, the discovery intuitively of line inspection personnel and maintainer, remove a hidden danger in advance, avoid accident to enlarge.
The utlity model has following advantage and good effect:
1, the thermosensitive colour-changing insulated protective cover of difformity, specification and size be can manufacture and design, electric equipment or distribution line conductor junction supplementary insulation in the transformation of distribution network insulating are applicable to;
2, the discoloring temperature of thermosensitive colour-changing insulated protective cover is 70 ℃～90 ℃, and its color takes place to change significantly, can reflect conductor local overheating defective intuitively;
3, thermosensitive colour-changing insulated protective cover product structure is simple, easy for installation.
In a word, the utility model is applied to during the distribution network insulating transforms, and not only can play the insulation protection effect to the contact in the electric equipment, function that can also the changeable colour of utilization own, and warning in advance equipment fault situation, the accident that prevents takes place.
