Description
Technical field
The utility model relates to a kind of distribution box of transformer substation cable screening wire wood properly test device, belongs to substation cable wood properly test technical field.
Background technology
Shielding line uses conductance cloth, the transmission line that netted braided wire wraps up signal wire, pass through shielding line, electromagnetic screen is provided with between interference source and secondary loop, make induction magnetic flux can not enter secondary loop, eliminate the induced voltage of secondary circuit, external magnetic force line major part is displaced in screen layer, and be not associated with screen layer inside conductor, thus induced potential can not be produced on wire, in entering signal source, maskable external interference source, interference is produced to signal transmission, crosstalk in shielding line between each pair of cable, reduce the loss of signal transmission simultaneously.
When shielding line fracture or unshielded line; electromagnetic interference signal easily causes malfunction or the tripping of protective relaying device and automatic safety device; cause the phenomenon such as data corruption and deadlock of supervisory system; the electronic devices and components in the insulation of secondary circuit and protective device can be damaged time serious, the safety of electrical network is constituted a serious threat.
According to related data statistics, the main cause using underproof copper-clad aluminum conductor to substitute pure copper wire to cause its corrosion cracking as cable screening wire.Because shielding line diameter only has 0.1mm, sectional dimension is very little, when using copper-clad aluminum conductor, the layers of copper only having top layer very thin plays a role, often owing to manufacturing or plaiting the hair and occur breakage in installation process, aerial steam effect issues pig copper aluminium electrode reaction and cataclasm rapidly thus lose function, constitutes a serious threat to the safety of electrical network.Therefore, detection streamer shielding line material seems particularly urgent and necessary.
Summary of the invention
The purpose of this utility model is, provides a kind of distribution box of transformer substation cable screening wire wood properly test device, can fast, convenient, accurately differentiate cable screening wire material and structure is simple, practical.
The technical solution of the utility model is, distribution box of transformer substation cable screening wire wood properly test device is made up of worktable, pointing machine, polished machine, microscope, notebook computer and printer.Worktable is divided into two-layer up and down, lower floor workspace has pointing machine and polished machine; Workspace, upper strata is provided with microscope, notebook computer, printer.
Pointing machine is only the cable screening wire of 0.1mm for inlaying diameter, be convenient to sample preparation and observe;
Polished machine be used for sanding and polishing inlay after cable screening wire sample;
Microscope, for observing the cable screening wire sample after sanding and polishing and taking image, is transferred to the notebook computer that cable screening wire Material Identification software is housed;
Printer is for printing testing result.
The beneficial effects of the utility model are, the utility model provides one cable screening wire wood properly test device accurately and reliably, avoid and use underproof shielding line and corrosion cracking occur and then threatens electricity net safety stable.
