Abstract
The utility model relates to a three -phase integral type current transformer, electrically conductive bar copper including the vertical range of three equidistant parallels, three looks current transformer coil is respectively placed around corresponding electrically conductive bar copper, there is the insulator three electrically conductive bar copper middle part pouring, the insulator holds three looks current transformer coil wherein, it has three -phase business turn over wire sleeve to pour into a mould respectively in the electrically conductive bar copper outside of insulator side and below, it has respectively the live test binding post who corresponds with three electrically conductive bar coppers to settle on an insulator side, and settle and to have respectively the secondary binding post who answers with three three -phase current transformer coil pair. The utility model provides a present three -phase integral type current transformer installation need to install respectively earlier the three -phase sleeve pipes, and then installation three -phase integral type current transformer's loaded down with trivial details step, switchgear's reliability and stability when having realized installation three -phase integral type current transformer.
Description
Technical field
The utility model belongs to current transformer technical field, particularly a kind of Integral three-phase current transformer for gas insulation switch cabinet.
Background technology
Along with the Fast Construction of intelligent grid, miniaturized, intelligent gas insulation switch cabinet equipment uses in a large number, in order to meet the needs that intelligent grid is built, switchgear for intelligent grid needs to install threephase current transformer, these instrument transformers are generally all installed to around its vicinity or cable, so just larger demand is proposed to installing space, and the intellectuality of present switchgear and the miniaturized trend having become switchgear development, therefore three-phase sleeve pipe is reduced, the installing space of threephase current transformer becomes the capable starting point solving this problem of gas insulation switch cabinet.The settling mode of current main flow adopts Integral three-phase current transformer, or adopt straight-through current transformer and split type three-phase sleeve pipe partial installation; Although meet the requirement of installing space like this; But install and need first respectively three-phase sleeve pipe to be installed, and then Integral three-phase current transformer is installed, installation steps are more loaded down with trivial details, not only to consider fixing three-phase sleeve pipe, also will design the support of fixed current instrument transformer, installation difficulty is comparatively large, installs careless slightly, sleeve pipe will be subject to the Action of Gravity Field of current transformer, and affect the reliability and stability of switchgear.
Summary of the invention
The purpose of this utility model is for the deficiencies in the prior art, and proposes a kind of Integral three-phase current transformer.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of Integral three-phase current transformer, comprise the conduction copper rod of three equidistant parallel vertical arrangements, three phase current mutual inductor coils are respectively placed around correspondence conduction copper rod, insulator is cast with in the middle part of three conduction copper rods, insulator by three phase current mutual inductor receive coil wherein, three-phase inlet-outlet sleeve is cast with respectively outside the conduction copper rod of side and below on insulator, insulator one side is mounted with and conducts electricity live testing binding post corresponding to copper rod respectively with three, and be mounted with secondary wiring terminals corresponding with three threephase current transformer coils respectively.
And, be shaped with in the upper end of conduction copper rod the screwed hole be connected with gas insulation switch cabinet inner conductor, be shaped with the screwed hole for installing cables annex in the lower end of conduction copper rod.
And described insulator builds by the monomer nylon containing glass 10% rectangular structure formed, and is shaped with seal groove, is equidistantly shaped with installation fixing hole on the surface along the cuboid inside seal groove at the lower surface edge place of this cuboid.
And the three-phase inlet-outlet sleeve above described insulator is the three-phase inlet-outlet sleeve of standard European tapering.
Advantage of the present utility model and good effect are:
The utility model solves the installation of current Integral three-phase current transformer to be needed first to install three-phase sleeve pipe respectively, and then the tedious steps of Integral three-phase current transformer is installed, achieve the reliability and stability of switchgear when installing Integral three-phase current transformer.
