Abstract
The utility model provides a totally closed small -size current transformer, it includes that primary coil, secondary coil, secondary binding post, iron core, P1 end binding post, P2 hold binding post, insulator and mounting plate, the iron core is the annular, and secondary coil is around on the iron core, and primary coil passes the iron core and detains mutually with secondary coil, and primary coil sets up in secondary coil's top, and secondary binding post is drawn forth to secondary coil's lower part, and P1 end binding post and P2 end binding post are drawn forth to primary coil's upper portion, and primary coil and secondary coil seal in the inside of insulator, and the insulator bottom sets up primary coil 2. The performance of iron core is superior to semi -closed structure's laminated core performance, and primary coil goes up the bottom phase with secondary coil and detains the design, makes the space obtain the rational utilization, secondary coil seals in inside, need not brush semiconductive varnish, avoids producing the magnetic leakage, improves mutual -inductor life, secondary binding post draws forth the side bottom the insulator, easy to assemble and use.
Description
Technical field
This utility model relates to field of power transformation, is specifically related to a kind of totally-enclosed shape small size current mutual inductor.
Background technology
At present the current transformer of switch cubicle is due to the shape of inner-core and structure, space can not be reasonably utilized, the volume causing current transformer is excessive, can not meet user's requirement to product miniaturization, meanwhile, similar current transformer mostly is semi-closed structure, semi-enclosed voltage transformer leaks outside due to iron core, leakage field is big, and shelf depreciation is the most up to standard, makes life of product be greatly shortened.
Summary of the invention
The defect existed in view of prior art, this utility model provides a kind of totally-enclosed shape small size current mutual inductor, and it can reach optimization Magnet performance, it is to avoid produces leakage field, improves transformer service life.
For reaching above-mentioned purpose, this utility model provides a kind of totally-enclosed shape small size current mutual inductor, and this product is the semiclosed product of LCZ-35() innovative product of type transformer.Its installation dimension is completely the same with LCZ-35 product, facilitates the transformation of original aging equipment, increase-volume, upgrading, only need to be changed by transformer during replacing.A kind of totally-enclosed shape small size current mutual inductor, it includes primary winding, secondary coil, secondary wiring terminals, iron core, P1 terminated line terminal, P2 terminated line terminal, insulator and mounting base；Iron core is annular, secondary coil is centered around on iron core, primary winding interlocks through annular core with secondary coil, primary winding is arranged on the top of secondary coil, and the bottom of secondary coil is drawn secondary wiring terminals and (comprised the terminal of current/voltage, specifically have how many, determine according to design parameter), P1 terminated line terminal and P2 terminated line terminal are drawn in the top of primary winding, and primary winding and secondary coil are encapsulated in the inside of insulator, and insulator foot arranges mounting base.Described secondary wiring terminals is drawn by insulator foot side.Described insulator is the entirety of epoxy resin mixed glue cast.P1 terminated line terminal, P2 terminated line terminal are a leading-out terminal.
Metering coil uses non-crystaline amorphous metal, and precision can meet 0.2S level requirement.
The beneficial effects of the utility model: convenient installation, carrying, cost is lower simultaneously, meets low consumption, environmental requirement；Secondary coil uses toroidal core structures, and the performance of iron core is better than the laminated core performance of semi-closed structure, and primary winding and secondary coil interlock design up and down, make space obtain Appropriate application, reduce the volume of transformer；Using full-closed structure, inside can add shielding processing, reduces shelf depreciation；Secondary coil is encapsulated in inside, without brush semiconductor varnish, it is to avoid produce leakage field, improves transformer service life；Secondary wiring terminals is drawn by insulator foot side, convenient installation and use.
