Description
Technical field
The present invention relates to electric field, and in particular to a kind of insulating boot for low-voltage live line work.
Background technology
In low-voltage live line work, exposed live wire is carried out temporary insulation parcel be the work that must complete in the industry
Hold.It is to take most commonly used method at present using insulated electro adhesive plaster parcel live wire.It is dielectrically separated from using electric adhesive plaster
Protection, mainly there is following shortcoming：
First, insulated using electric adhesive plaster and wrap up trivial operations, wasted time and energy by mutually parcel, insulation processing process is easy in itself
Cause accidental shock, there is larger security risk；
Second, operating personnel is easily in the case where idea of leaving things to chance is driven, and clear-cut operation of taking a risk is without insulation processing；
3rd, packing technology is varied with each individual, and electric shock accidents is easily caused in the case of parcel is incomplete, has certain safety
Hidden danger；
4th, insulating tape belongs to consumptive material, and Material Cost is added during use.
The content of the invention
The technical problems to be solved by the invention are that practical electric adhesive plaster carries out parcel trivial operations, wasted time and energy, and are used
Larger potential safety hazard in journey be present and Material Cost is higher, and it is an object of the present invention to provide a kind of insulation for low-voltage live line work
Cover, in low-voltage live line work, to substitute the electric adhesive plaster used in powered operation process, reaching to the temporary of powered nuditing wire
The effect of when property insulation parcel, plays a part of the be dielectrically separated from protection good to electrical body, high-definition can improve powered
Operating efficiency, potential safety hazard is reduced, and beneficial to material is saved, reduce cost of manufacture.
The present invention is achieved through the following technical solutions：
A kind of insulating boot for low-voltage live line work, the insulating boot include the outer cylinder body and inner cylinder being set-located
Body, the outer cylinder body and inner barrel connect at axial one end open, and are between outer cylinder body madial wall and inner barrel lateral wall
Annular hollow chamber.
It is set-located by the outer cylinder body and inner barrel that are connected at axial port and forms insulating boot agent structure, is used
When, directly insulating boot is located on live wire, and live wire is directly contacted with inner barrel inwall, interference fits clamping is set
Put.This insulating boot is used in low-voltage live line work, to substitute the electric adhesive plaster used in powered operation process, reaches to powered exposed
The effect of the temporary insulation parcel of wire, plays a part of the be dielectrically separated from protection good to electrical body, can be high-definition
Livewire work efficiency is improved, reduces potential safety hazard；To be annular hollow chamber between outer cylinder body madial wall and inner barrel lateral wall,
Ensure that insulation is covered with enough overall radial thickness, and outer cylinder body and inner barrel separate setting, insulating boot is in long-term use of mistake
Inner barrel causes decreasing insulating with live wire abrasion in journey, does not interfere with outer cylinder body insulating properties, there is good safety
Performance, it is additionally favorable for saving Material Cost；In addition the inside and outside footpath size of insulating boot according to the size of wire diameter, can be adjusted, so as to
The insulating boot of different size is produced, there is diversity.
Preferably, the outer cylinder body and the inner barrel radially smooth excessively connection at axial one end open.
By outer cylinder body and inner barrel, the radially smooth excessively connection at axial one end open, can be formed with certain radian
Smooth structure, both ensure when live wire is inserted into inner barrel by opening and to be contacted with less frictional resistance, and can
Prevent the opening of corner angle from causing necessarily to damage to live wire cable.
Preferably, the side wall of the outer cylinder body by the axial one end open successively radially, axially in outer cylinder body
Extension forms the inner barrel.
Inner barrel is extended by outer cylinder body to be obtained, and outer cylinder body and inner barrel is smoothly connected in cover mouth, is formd with certain
The insulating boot cover mouth of thickness, ensure that enough support forces form the cover mouth-shaped with live wire form fit, be easy to staff
Quickly insulating boot is located on live wire.
Preferably, the closing of the outer cylinder body axial direction other end, the inner barrel axially another end opening, and the axle of inner barrel
It is less than the axial length of outer cylinder body to length.
The outer cylinder body of now one end closing mainly plays good closing insulation protection, and what axial both ends were open
Inner barrel mainly plays fixed live wire, beneficial to saving material.
Preferably, the internal diameter of the inner barrel is inwardly gradually reduced by opening vertically.
According to the structure of above-mentioned insulating boot, its using when there is anti-drop function, the reliability of insulation parcel can be increased.
The principle of anti-drop function is that inner barrel internal diameter is gradually reduced, and insulating boot inwall can be squeezed power during use, so as to be formed
Frictional resistance prevents live wire from coming off；Also it can use the material with certain elasticity and ductility that inner barrel is made simultaneously, then
Anti-dropout is better.
Preferably, two are offered in the side wall of the inner barrel vertically and breaks line, described two break line with inner cylinder
Plane where body axis is that basal plane is in specular.
Opened up on inner barrel and break line, ensured that insulating boot has the characteristic easily won, practicality can be strengthened.When completion makes
When needing to remove insulating boot after, it is only necessary to apply modest pressure to outer cylinder body, its inner cylinder body sidewall can be made to break line along twice
Open, reach the effect of separation inner barrel inwall and wrapped wire, you can easily outwards remove insulating boot.
Preferably, the outer cylinder body and inner barrel are made of electro-insulating rubber.
This insulation is covered with to be made up of electro-insulating rubber, has good insulation properties, and inside and outside wall has certain elasticity and prolonged
Malleability.Live wire and inner barrel internal wall transitions are coordinated during use, insulating boot inner barrel can be squeezed power, be rubbed so as to be formed
Wiping resistance prevents from coming off.
Preferably, the insulating boot also includes exterior visual data separation coding, and the coding of distinguishing is used for for differentiation
The insulating boot of different scenes and different live wire targets.
Preferably, the outside can make information include color, outer logo code.
The exterior visual information such as its color, outer logo code can be carried out coding differentiation by insulating boot, be applicable more with facilitating
Application scenarios, strengthen its practicality.For example, in low voltage three-phase application, can be by three or four insulating boots make respectively and electric power
Yellow, green, red, blue color corresponding to phase color；In the application scenarios of charged for replacement single-phase electric energy meter, four insulating boots can be added respectively
Add identification code " L enters " " L goes out " " N enters " " N goes out " to be distinguish between (L identifies for live wire, and N identifies for zero line), be easy to quick distinguish to distinguish
Not.
Preferably, two or more insulating boots are interconnected to constitute insulating boot group.
Multiple insulating boots can be applied in combination, two, three or four insulating boots are connected from structure, be easy to take and
Keeping, enhances easy-to-use degree, is more applicable single-phase and three-phase low-voltage electricity system.
