Abstract
The utility model discloses a busbar suitable for current transformers of different specifications. The busbar comprises a front segment bar, a middle segment bar and a back segment bar, wherein adjacent ends of the front segment bar and the back segment bar are provided with bolt holes; the two ends of the middle segment bar are provided with bolt holes matched with the two bolt holes respectively; bolts pass through the bolt holes at the two ends of the middle segment bar respectively, and are fixedly connected with the bolt holes in the adjacent ends of the front segment bar and the back segment bar; the distance between the front segment bar and the back segment bar is 10 centimeters; the bolt holes in the adjacent ends of the front segment bar and the back segment bar are waist round holes; the axial lines of the two screw holes are positioned on the same straight line; the distance between near ends of the two screw holes is smaller than or equal to 10 centimeters while the distance between far ends is more than or equal to 20 centimeters; and the width of the middle segment bar is smaller than or equal to 10 centimeters. Due to the adoption of a three-segment design, the busbar is suitable for mutual inductors of various models, installation personnel do not need to break bars and open holes on field, the installation quality is improved, and the working efficiency is increased.
Description
Technical field
The utility model relates to the busbar in the power system device mesolow metering cabinet, is specifically related to a kind of busbar of segmented.
Background technology
Distribution transformer low-pressure side metering device and the high dedicated transformer metering device that forces down client's (referring generally to the user of factory) of electric low-temperature measurement in resident's distribution engineering, do not use the common current instrument transformer of client or instrument factory configuration, should unify to install through the qualified metering current mulual inductor of electric company's verification, this just makes each station power distribution step down side, all need the metering current mulual inductor of electric company's assets be installed at the scene by dress table personnel.The inner busbar size of the low-temperature measurement cabinet of present each manufacturer production, the equal disunity of arrangement mode, the low-voltage current mutual inductor specification of the different model of different manufacturers production also is not quite similar, cause the situation that often needs disconnected rows of openings when the metering instrument transformer is installed at the scene, perplexing the metering installation personnel for a long time always.On-the-spot aftertreatment time and effort consuming to busbar, and the technology of field fabrication, precision etc. are had relatively high expectations, make the actual installation effect also relatively poor, problems such as loose contact, the stressed fracture of busbar supporting insulator often appear after the operation.
Summary of the invention
The objective of the invention is to: at the problem of above-mentioned existence, provide a kind of busbar that is applicable to the different size current transformer, adopt the syllogic design, install at the scene of convenient metering instrument transformer.
The present invention is achieved by the following technical solutions:
A kind of busbar that is applicable to the different size current transformer comprises leading portion row, stage casing row, back segment row; Described leading portion row and back segment row's abutting end is provided with bolt hole, and stage casing row's two ends are respectively equipped with the bolt hole that matches, and bolt passes the bolt hole at row two ends, stage casing respectively and the bolt hole of leading portion row and back segment row abutting end is connected and fixed.
As the present invention further optimization scheme, described leading portion row is 10cm with back segment row abutting end spacing.
As the present invention further optimization scheme, described leading portion row is the oval hole with the bolt hole of back segment row's abutting end.
As the present invention further optimization scheme, the axial line of the bolt hole of described leading portion row and back segment row's abutting end is on same straight line, and its phase near-end spacing is less than or equal to 13cm, and phase far-end spacing is more than or equal to 20cm.
As the present invention further optimization scheme, described stage casing row's width is less than or equal to 10cm.
The present invention has following beneficial effect:
One, busbar of the present utility model adopts the syllogic design, and stage casing row couples together leading portion row and back segment row by bolt, makes installation personnel not need on-the-spot disconnected rows of openings, and the quality of installation has obtained guarantee, has also improved operating efficiency simultaneously.
Two, busbar of the present utility model, leading portion row is 10cm with back segment row's spacing, leading portion row arranges with back segment and has circular elongated pore, and the close end distance in two holes is from smaller or equal to 13cm, phase far-end distance is more than or equal to 20cm, and this just makes the utility model can be applicable to the goat's horn instrument transformer of various models.
Three, busbar of the present utility model, stage casing row's width makes the utility model can be applicable to the punching instrument transformer of various models smaller or equal to 10cm.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the vertical view of Fig. 1.
Embodiment
As shown in Figure 1, a kind of busbar that is applicable to the different size current transformer comprises leading portion row 1, stage casing row 2, back segment row 3; Described leading portion row 1 is provided with bolt hole with back segment row 3 abutting end, and stage casing row 2 two ends are respectively equipped with the bolt hole that matches, and bolt passes the stage casing respectively and arranges the bolt hole that the bolt hole at 2 two ends and leading portion row 1 and back segment arrange 3 abutting ends and be connected and fixed.Spacing between leading portion row 1 and the back segment row 3 is 10cm.
Shown in Figure 2, leading portion row 1 is the oval hole with the bolt hole of back segment row 3 abutting end, and the aperture all is 14mm.The axial line in two-screw hole is on same straight line.By investigation and the measurement to the goat's horn instrument transformer of various models on the market, from being designed to smaller or equal to 10cm, phase far-end distance is designed to more than or equal to 20cm with the close end distance in two-screw hole, and this just makes this busbar can be applicable to the goat's horn instrument transformer of various models.
Still as shown in Figure 2, row 2 apertures of tightening up a screw the hole, stage casing are 14mm, and the pitch-row in two holes is at 13cm～20cm.By investigation and the measurement to the punching instrument transformer of various models on the market, stage casing row 2 width is designed to smaller or equal to 10cm, this just makes this busbar can be applicable to the punching instrument transformer of various models.
