Abstract
The invention discloses a convenient-to-mount current transformer which comprises an annular transformer body and a rubber fixing sleeve. A central hole of the transformer body is provided with a spring clamp, mounting holes are uniformly arranged on two sides of the transformer body circumferentially, fixing pins matched with the mounting holes are arranged on the inner wall of the rubber fixing sleeve, and ribbon holes used for allowing ribbons to penetrate and pass are arranged at two ends of the rubber fixing sleeve. The convenient-to-mount current transformer has the advantage that the transformer is enabled to be simple to mount and firm in fixing.
Description
Technical field
The present invention relates to a kind of instrument transformer that detects the electric current of transformer, specifically a kind of current transformer of being convenient to installation.
Background technology
Cable straight-through current transformer is the product often adopting in electric power system, as current measurement or relaying protection, use, because what its line adopted is high voltage insulation cable, supporting current transformer is that form of bus bars is set in high voltage insulation cable outside one time, realizing current measurement uses, in order to prevent that instrument transformer body and high-tension cable from sliding, generally with holder, realize the fixing of instrument transformer body now, so not only need separately for instrument transformer body is set up fixed head, the higher place of cable particularly, position itself is bad to be determined, re-use bolt or screw is fixed, make to install the whole process of current transformer comparatively loaded down with trivial details.
Summary of the invention
The object of the invention is, provide a kind of use at transformer primary side, to be convenient to the current transformer of installing.
In order to achieve the above object, technical scheme proposed by the invention is: the current transformer of being convenient to installation, comprise annular instrument transformer body and rubber fixed cover, described instrument transformer body centre bore is provided with spring clip, in instrument transformer body both sides, hoop is evenly provided with installing hole, described rubber fixed cover inwall is provided with the fixing feet coordinating with installing hole, and these rubber fixed cover two ends are provided with the tie-hole for interspersed band.
The invention has the advantages that, in installation process, fixing feet and installing hole cooperation are buckled together rubber fixed cover and instrument transformer body, instrument transformer body is wrapped in rubber fixed cover, then electric wire needs being detected is through the centre bore of instrument transformer body, strain relief clamp is located in spring clip at the beginning of one, rubber fixed cover two ends are provided with the tie-hole for interspersed band, band can be penetrated in tie-hole, by band, rubber fixed cover two ends are closely fixed on cable, and the secondary cable of instrument transformer body also can be fixed in rubber fixed cover in the lump.
Further, in order to make rubber fixed cover and cable fixing tightr, described rubber fixed cover two ends are respectively provided with three tie-hole, and six roots of sensation band is penetrated in tie-hole, a plurality of positions and the cable of rubber fixed cover link together, and make rubber fixed cover be connected more firmly with cable.
Finally, in order to make the secondary cable of instrument transformer body that rubber fixed cover is produced and be disturbed, described secondary leading-out terminal is arranged on the side of instrument transformer body, and rubber fixed cover inwall is provided with rubber groove.Secondary leading-out terminal is arranged on the side of instrument transformer body, make secondary leading-out terminal in rubber fixed cover, have enough spaces, can not disturb the connection of rubber fixed cover and instrument transformer body, secondary wire is stuck in rubber groove simultaneously, cable can not collected together in rubber fixed cover.
Accompanying drawing explanation
Fig. 1: be convenient to install and the structural representation of the casing of the transformer of lifting for of the present invention.
Embodiment
As shown in Figure 1 be a kind of current transformer of installing be convenient to, comprise annular instrument transformer body 1 and rubber fixed cover 2, instrument transformer body 1 centre bore is provided with spring clip 3, at instrument transformer body 1 both sides hoop, be evenly provided with installing hole 4, rubber fixed cover 2 inwalls are provided with the fixing feet coordinating with installing hole 4, and these rubber fixed cover 2 two ends are provided with the tie-hole 6 for interspersed band.
In the installation process of instrument transformer body 1, fixing feet and installing hole 4 cooperations are buckled together rubber fixed cover 2 and instrument transformer body 1, instrument transformer body 1 is wrapped in rubber fixed cover 2, then electric wire needs being detected is through the centre bore of instrument transformer body 1, make strain relief clamp spring clip 3 interior as one at the beginning of location, rubber fixed cover 2 two ends are provided with the tie-hole 6 for interspersed band 7, band 7 can be penetrated in tie-hole 6, by band 7, rubber fixed cover 2 two ends are closely fixed on cable, and the secondary cable of instrument transformer body 1 also can be fixed in rubber fixed cover 2 in the lump.
Rubber fixed cover 2 two ends are respectively provided with three tie-hole 6, and six roots of sensation band 7 is penetrated in tie-hole 6, and a plurality of positions and the cable of rubber fixed cover 2 link together, and make rubber fixed cover 2 be connected more firmly with cable.
Secondary leading-out terminal 5 is arranged on the side of instrument transformer body 1, and rubber fixed cover 2 inwalls are provided with rubber groove 8.Secondary leading-out terminal 5 is arranged on the side of instrument transformer body 1, make secondary leading-out terminal 5 in rubber fixed cover, have enough spaces, can not disturb the connection of rubber fixed cover 2 and instrument transformer body 1, secondary wire is stuck in rubber groove 8 simultaneously, cable can not collected together in rubber fixed cover 2.
