Description
Technical field
The utility model belongs to electric energy metrical field, relates to current transformer, and copper bar installed by especially a kind of instant-plugging current transformer.
Background technology
Along with the development of electric power system, new requirement is proposed to measurement of power and measurement.Current transformer is the visual plant of electric energy metrical and measurement in electric power system, and safe, the reliable and economical operation of its accuracy and reliability and electric power system is closely related.But existing current transformer only could detect current transformer and change under the state of system blackout, impact is produced, life.
By retrieval, find following disclosed patent documentation:
A kind of current transformer fixed structure (CN203085346U), comprise current transformer, current transformer supporting component, current transformer fixed mount, also comprise current transformer supporting bracket, current transformer is fixed on current transformer fixed mount by described current transformer supporting bracket and current transformer supporting component; Described current transformer supporting bracket is fixed on current transformer fixed mount by insulator.Advantage of the present utility model: while the safe and reliable installation component adopting current transformer device producer to provide, and can not magnetic disturbance be caused for around Sensitive Apparatus.
Above-mentioned patent is different from the technical problem that the application solves, and technical scheme is different, not yet finds that there is identical patent literature of dealing with problems with the application.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, and copper bar installed by the novel instant-plugging current transformer provide a kind of and can detect current transformer without the need to having a power failure, changed.
The technical scheme that the utility model technical solution problem adopts is:
Copper bar installed by a kind of instant-plugging current transformer, comprise base, a multipair bindiny mechanism and multiple secondary and connect jack, laterally a multipair bindiny mechanism is fixedly mounted with in uniform interval at the end face of base, often pair of bindiny mechanism's equal interval symmetry is packed in longitudinal both sides of base top surface, between often pair of bindiny mechanism, the end face of base is all shaped with two secondaries connection jacks, connects jack be all shaped with a secondary wiring terminals at the sidewall of base each secondary corresponding.
And, a described bindiny mechanism comprises four square frame underframe, clamping plate and primary connection copper coin, four square frame underframe are packed in the end face of base, separately and respectively to upper right-angle bending extend in the middle part of the top board of four square frame underframe and make two clamping plate, press-fit primary connection copper coin at the plate top surface of four square frame underframe.
And bottom connects a spring between two clamping plate.
Advantage of the present utility model and good effect are:
This copper bar connects current transformer by the mode of grafting, without the need to coiling direct on current transformer, wiring, makes it can carry out changing, detecting under system band electricity condition, avoids the economic loss having a power failure and cause, improves operating efficiency.

Embodiment
Below in conjunction with accompanying drawing, also by specific embodiment, the utility model is described in further detail, and following examples are descriptive, are not determinate, can not limit protection range of the present utility model with this.
Copper bar installed by a kind of instant-plugging current transformer, comprise base 6, a multipair bindiny mechanism and multiple secondary and connect jack 8, laterally a multipair bindiny mechanism is fixedly mounted with in uniform interval at the end face of base, often pair of bindiny mechanism's equal interval symmetry is packed in longitudinal both sides of base top surface, between often pair of bindiny mechanism, all install a current transformer 9, P1 end and the P2 end of current transformer insert in two slots of a pair bindiny mechanisms respectively.Between often pair of bindiny mechanism, the end face of base is all shaped with two secondaries connection jacks, and secondary connects the jack current transformer S1 end corresponding with it and S2 end is connected by conductor 10.Connect jack at the sidewall of base each secondary corresponding and be all shaped with a secondary wiring terminals 5.
A described bindiny mechanism comprises four square frame underframe 3, clamping plate 1 and primary connection copper coin 4, four square frame underframe are packed in the end face of base, separately and respectively to upper right-angle bending extend in the middle part of the top board of four square frame underframe and make two clamping plate, slot is formed between two clamping plate, the once end of plug-in mounting current transformer between two clamping plate, press-fits primary connection copper coin at the plate top surface of four square frame underframe.Four described square frame underframe and clamping plate are made by elasticity copper coin, and in order to increase the clamping force between two clamping plate, between two clamping plate, bottom connects a spring 2.
Fixing for the ease of installing, an installing hole 7 is respectively shaped with in the corner of base.
The using method of this copper bar is:
Between the three couples bindiny mechanism three current transformers being arranged on respectively copper bar, P1 end and the P2 end of each current transformer are inserted between two clamping plate of a bindiny mechanism corresponding thereto respectively, and bus is connected with two primary connection copper coins respectively; The S1 end of each current transformer is all inserted into the secondary corresponding with it by conductor with S2 end and is connected in jack, and detecting instrument is connected with the secondary wiring terminals of base side wall.This copper bar avoids direct coiling or line on current transformer, when needs maintenance or when changing current transformer, does not need power-off, takes out stitches, directly upwards extracted by current transformer, very convenient.
Above-described is only preferred implementation of the present utility model; it should be pointed out that for the person of ordinary skill of the art, under the prerequisite not departing from utility model design; can also make some distortion and improvement, these all belong to protection range of the present utility model.
