Description
Technical field
The invention belongs to power safety technique field, more particularly to a kind of drainage system for current transformer.
Background technology
Power network arrangement is extensive, and supply load is big, the connection contact of power equipment current carrying element（Abbreviation joint or the wiring palm）
The defects of heating, is more serious.For the current transformer of open air, the situation hinge that the wiring palm of its both sides easily generates heat is serious, reason
Be contact surface aoxidizes serious and current carrying area deficiency.The method handled at present has carries out cleaning polishing to contact surface, stops
The electric time is short but heating defect easily recurs；Another kind is exactly the structure type for changing the wiring palm or the electric current for changing bigger current-carrying capacity
Transformer, this method processing is more thorough but power off time is grown, and cost is larger.
The content of the invention
The present invention is the above-mentioned at least one technological deficiency of solution, there is provided a kind of drainage for current transformer fills
Put, possess anti-corrosion, oxidation resistance, the effect of the conductive current carrying area of increase, and do not changing the primary current mutual inductor interstar connection palm
Structure under the premise of, the device simple installation, shorten time of interruption maintenance.
The technical scheme is that：A kind of drainage system for current transformer, wherein drainage system include connection
Portion and two clinch for being connected to connecting portion both ends, clinch form U-shape structure with connecting portion, and clinch is provided with some spiral shells
Pit, connecting portion are provided with some copper strips, and clinch is overlapped on the wiring palm of current transformer.
The drainage system of U-shape structure is overlapped on the wiring palm of current transformer, is fixedly connected by screwed hole, wherein connecting
Socket part is provided with copper strips.The device adds the area of current loop and conductive current-carrying, and prevention current transformer overheats, and not
Under the premise of the structure for changing the primary current mutual inductor interstar connection palm, simple installation, time of interruption maintenance is shortened.
Further, clinch is embedded in screwed hole by bolt and is fixedly connected with the wiring palm of current transformer.Stable connection,
Convenient disassembly.
Further, a diameter of 13mm-15mm of some screwed holes.The close journey of sufficiently large screwed hole enhancing connection
Degree.
Further, the corner radius of U-shape structure is 19mm -21mm.Clinch is set enough gaps, convenient overlap joint to be present
Portion is overlapped on wiring palm.
Further, the thickness of clinch is 9mm-11mm, length 80mm-90mm.Increase the area of conductive current-carrying, in electricity
Energy fast guiding is radiated when current transformer overheats.
Further, the surface of clinch uses electronickelling or silver.The surface of clinch uses electronickelling or silver, improves anti-
The rotten ability with conduction.
Further, copper strips is tired builds up U-shape structure and is molded with pressure welding of clinch.Closely tied between copper strips and clinch
Close in one, ensure enough excessively stream performances, strengthen conductive capability.
The beneficial effects of the invention are as follows：
（1）Make being conductively connected for current transformer more convenient, reliable, safe, protect each associate device not influenceed by external force.
（2）Absorb noise and vibration caused by current transformer operation.
（3）The area of current loop and conductive current-carrying, prevention current transformer overheat are added, and is not changing former electricity
Under the premise of the structure of the current transformer wiring palm, simple installation, time of interruption maintenance is shortened.
（4）The surface of clinch uses electronickelling or silver, improves anti-corrosion and conductive ability.
