Description

A kind of cross interconnected anti-mistaking of high-tension cable connects cross interconnected case
Technical field
The present invention relates to cross interconnected case applied technical fields, more particularly, to a kind of cross interconnected system of high-tension cable The system cross interconnected case of error connection proof.
Background technology
Urban distribution network generally use high voltage single-core cable transmit electricity, when cable core have electric current by when, in electrical cable aluminium sheath On have induced voltage generation, and cable load is bigger, circuit is longer, and induced voltage is higher.If threephase cable circuit is completely right Electric current is also full symmetric in title, three-phase circuit, then the voltage incuded in threephase cable aluminium sheath is full symmetric, their vector sum It is zero.Using this principle, three-phase aluminium sheath interconnection is arranged in joint location in longer cable run, by intersecting company twice It connects so that entire cross interconnected section of induced voltage is smaller, Fig. 3 show cross interconnected section of three company of intersecting of electrical cable aluminium sheath Binding composition.
If but there is wiring error in three-phase interconnection position so that entire cross interconnected section of voltage can not be offset, and be incuded Voltage will generate excessive circulation in sheath, cause cable jacket ablation, or even breakdown.In practice, three intersections of cable Fork connection realizes that cable connector both ends aluminium sheath connects coaxial cable " core " and " skin " respectively, by coaxial by cross interconnected case Cable introduces in cross interconnected babinet, and coaxial cable " core " and " skin " are separately connected two groups of wire clamps in babinet, pass through copper between wire clamp The different connection types of row realize the cross interconnected of electrical cable aluminium sheath.
Existing cross interconnected case has no error connection proof design, when one cross interconnected section two cross interconnected case connections differ When cause, entire cross interconnected section of induced voltage will occur can not offset, circulation it is excessive it is existing as.Have a power failure in cable preventative It needs frequently to disconnect cross interconnected case in experiment, it is careless slightly wiring error occur, prestige is caused to high-tension cable safe operation The side of body.
