Abstract
The utility model discloses an indoor bus bar type zero sequence current mutual inductor and belongs to the technical field of zero sequence current mutual inductors. The main problem that currently, the zero sequence current mutual inductor which can be installed indoors in a bus-bar type mode does not exist is solved. The indoor bus bar type zero sequence current mutual inductor is characterized by comprising a mutual inductor main body composed of an inducing iron core and a coil, and a one-time side-penetrating bus bar hole is formed in the center. A cone-shaped insulation column is arranged on the mutual inductor main body. A secondary side connecting terminal is arranged on the insulation column. An umbrella cluster is arranged between the secondary side connecting terminal and the one-time side-penetrating bus bar hole. The mutual inductor main body is fixed on a bus bar through a connecting accessory. The connecting accessory comprises a rectangular iron plate and two screws. The indoor bus bar type zero sequence current mutual inductor has the advantages of being compact and safe in indoor bus-bar type installation and is mainly suitable for being installed in any position on the indoor bus bar.
Description
Technical field
The utility model belongs to the zero sequence current mutual inductor technical field.Be specifically related to a kind of indoor busbar installing type zero sequence current mutual inductor.
Background technology
At present, zero sequence current mutual inductor is current transformer with single-turn cored structure, generally is used for the supporting use of electrical protection apparatus.The zero sequence current mutual inductor of indoor installation on the present market, basically be divided into two kinds of open type and punchings, being primarily aimed at cable type installs, there is not the zero sequence current mutual inductor at indoor busbar formula installation, thereby cause instrument transformer can't be installed, brought inconvenience to installation.
Summary of the invention
The purpose of this utility model is exactly that a kind of zero sequence current mutual inductor that indoor busbar formula succinct, safety is installed of installing is provided at above-mentioned weak point.
Technical solution of the present utility model is: a kind of indoor busbar formula zero sequence current mutual inductor, comprise the current transformer body of being formed by inductive iron core, coil, central authorities are provided with primary side and wear the busbar hole, it is characterized in that: be provided with the taper insulated column in current transformer body, this taper insulated column is provided with the secondary side binding post; Wear between the busbar hole at secondary side binding post and primary side and to be provided with cluster parachute; Instrument transformer is fixed on the busbar by coupling, and this coupling is made up of the square iron plate of a block length and two screws.
The utility model is because by inductive iron core, on the basis of the current transformer body dress that coil is formed, be provided with the taper insulated column in current transformer body, be provided with the secondary side binding post at the taper insulated column, wear between the busbar hole at secondary side binding post and primary side and to be provided with cluster parachute, current transformer body is fixed on the busbar by coupling, this coupling comprises the square iron plate of a block length and two screws, not only increase creepage distance effectively, guarantee one, the safe spacing of secondary side, and under the situation of not damaging busbar, indoor busbar formula zero sequence current mutual inductor is fixed on any position of busbar.The utlity model has the characteristics that indoor busbar formula succinct, safety is installed of installing.The utility model is mainly used in being fit to peace zero sequence current mutual inductor in optional position on the indoor busbar.
Description of drawings
Fig. 1 is the utility model zero sequence current mutual inductor structural representation.
Fig. 2 is the utility model installation side view.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
As shown in Figure 1 and Figure 2.The indoor busbar formula of the utility model zero sequence current mutual inductor is made up of current transformer body 1, taper insulated column, secondary side binding post 2, cluster parachute 3 and coupling 6.Current transformer body 1 is made up of inductive iron core, coil etc., and is identical with existing zero sequence current mutual inductor structure.Current transformer body 1 is flat ring bodies, and central authorities are provided with the rectangle primary side and wear busbar hole 4, and current transformer body 1 is marked with P1.Current transformer body 1 is provided with the taper insulated column.Secondary side binding post 2 is arranged on the taper insulated column in the outer part the position, and the taper insulated column is marked with S1, S2, and secondary side binding post 2 and primary side are worn and be provided with cluster parachute 3 between the cable aperture 4.Coupling 6 is made of the square iron plate of a block length and two screws, is fixed on by set screw on any position of busbar 5.
