Description
Technical field
In the present invention relates to, low-voltage electrical cable branch field of accessories, be particularly related to one and exempt to block speediness embranchment device and implementation method, be suitable at the construction field (site) mineral insulated cable being carried out the application of branch's installation, when having solved traditional mineral insulated cable and using mineral cable T to meet feeder pillar branch, in its case, there is the problem that multiple cable point of cut-offs bring, to eliminate potential faults.
Background technology
In, in the laying installation work progress of low-voltage electrical cable, conventionally adopt mineral cable T to connect case and realize mineral insulated cable branch, mineral cable T connects the potential faults that feeder pillar brings.
1, mineral cable T connects feeder pillar inside and comprises binding post, when installation, will block main cable, by the binding post branch cable of transferring, owing to there being multiple cable point of cut-offs, thereby has the potential faults that produces fault.
The conductive material of the binding post that existing branch product adopts, is generally cast iron reverse mould, then through surface finish processing, finally to the zinc-plated processing in metal surface.
Due to material reason, zinc-plated have a larger difficulty, and indivedual binding post surface treatments are only often that simple to be easy to plating color.Here will illustrate especially, plating coloured silk is not the coat of metal, and plating coloured silk is only the silver color bright coating illusion after metal surface formation red copper is zinc-plated.Therefore, make very poor non-conductor material terminal and the cable conductors contact-making surface of conductance originally increase obstruct face, more reduce conductance.Be more prone to produce Carbon Deposit Phenomenon, in use, cause empty connection, and then cause power-off.
In addition, this kind of binding post only emphasized tightness, but ignored unlike material electric conductivity difference, and meanwhile, non-conductor material and cable contact-making surface are little, cause breakout overheated, have electric disaster hidden-trouble.
2, penetrating cable clamp Ye Shi branch product one of,
At present, penetrating cable clamp bans use of in most cities at home.Penetrating cable clamp is introduced French Xi Kamu wire clamp technology the earliest, and this technology explicitly points out as facing electricity application, and feature is that lower end electrical appliance power is little, and it is little to cable cover(ing) infringement that acupuncture point-like punctures cable jacket.
In the time that penetrating cable clamp is applied to cable branch, while differing greatly due to main cable cross section and branch cable cross section, there is very large danger in the method.Because penetrating cable clamp is in the time clamping the larger main cable in cross section, do not clip to the less branch cable in cross section, if continuing reinforcing tightens, until clamping branch cable, but the main cable outside, heavy in section now having clamped, because angle lifts greatly, This move is difficult to discover with range estimation, very easily forms empty connection.
In addition, in power supply-distribution system application, power cable is commonly YJV crosslinked cable, and cross-linked layer is between cable conductor and cable cover(ing).This layer is crosslinked harder.Penetrating cable clamp acupuncture is short and thick, cannot directly pierce through cable cross-linking layer, and when after moment of torsion broken screw, operator takes for wire clamp and cable conducting.Even if the inadequate conducting of wire clamp acupuncture and cable conductor, non-conductor material draw point Multi-contact face is also less than terminal.Cause breakout overheated, exist electric disaster hidden-trouble more obvious.
Above-mentioned traditional mineral cable T connects feeder pillar internal structure and has obvious defect, therefore need the mineral cable branch product of a kind of new structure of design and development to meet the needs of power supply and distribution of electric power system, and domestic there is no surmounts the novel mineral cable branch product appearance that existing product structure collectivity is conceived, how to address this problem and just become the problem that those skilled in the art will study and solve.
