The insulation pulse type transformer has reasonable and compact structure, avoids high-voltage sparkling, and runs reliably.
Description
Technical field
The utility model relates to a kind of pulse type transformer, belongs to high voltage electrical apparatus technical field, is a kind of high voltage (110KV electric pressure) insulation pulse type transformer that is applied to electric power system specifically.
Background technology
Pulse transformer is a kind of transformer of specific type.Its conversion be not sinusoidal voltage, neither ac square wave, but near the unipolar pulse of rectangle.Pulse transformer is mainly used in and raises or the reduction pulse voltage; Change the polarity of pulse; Set up the coupling between load resistance and the feeder line characteristic impedance; The flip-flop of insulating power supply part; As the synthetic inverting element etc. that reaches of power.Along with electronic technology development with rapid changepl. never-ending changes and improvements, in fields such as high-rating generator, radar, communication, medical treatment, nuclear physics, more and more to the demand in high pressure, highpowerpulse source, how little, in light weight, the function admirable of design volume, hypermutation are the problems of relatively being concerned about in the industry than, powerful pulse type transformer.Owing to be subjected to the restriction of factors such as dielectric strength, electric clear distance, volume, rarely have high voltage (110KV electric pressure) pulse type transformer on the China market at present.
How to research and develop a kind of insulation pulse type transformer, avoid high voltage arc, reduced volume, assurance reliable, this is the technical problem that needs to be resolved hurrily at present.
Summary of the invention
The purpose of this utility model is the deficiency that exists at prior art, and a kind of insulation pulse type transformer is provided, and it is rational in infrastructure, compact, avoids high voltage arc, reliable.
The purpose of this utility model is achieved by the following technical solution: a kind of insulation pulse type transformer, comprise iron core, coil, coil radome, fixed support, binding post, and it is characterized in that: described coil is wrapped in respectively in the coil radome; With cross-over block isolation and fixing, by insulating end ring isolation and fixing, iron core is fixed on the groove shaped fixed support with insulated bolt between coil and the iron core between coil and the coil.
To improvement of the technical scheme: described insulating end ring has oil duct.
To further improvement in the technical proposal: described cross-over block is " Gui " font sandwich construction.
To further improvement in the technical proposal: described binding post adopts a wrapped with insulation and a vacuum pouring moulding.
To further improvement in the technical proposal: described coil radome is that copper material, aluminium or semi-conducting material are made, and it is shaped as spherical or cylindrical, its edge welding or damascene conductive ring or semiconductive ring.
To further improvement in the technical proposal: described coil radome twines insulating material outward, and the coil radome twines a kind of material that insulating material is selected from high-tension cable paper, cardboard, crimped paper, kraft capacitor paper, winding insulating paper or the oil resistant rubber outward to be made.
To further improvement in the technical proposal: the insulating material of described parcel binding post is resinae or the pourable material of oil resistant rubber class.
The utility model compared with prior art has the following advantages and good effect:
The utility model all wraps up owing to high-tension coil, guaranteed its to earth electric field evenly, the conducting ring that uses high-tension cable paper and cardboard to make is used as insulation reinforcement and cutting oil clearance, adopt insulating end ring and " Gui " font cross-over block of band oil duct to fix coil, make it not influence heat radiation again by fixed coil.The groove shaped fixed support made from insulating material unshakable in one's determination supports, and fix with insulated bolt, binding post also adopts the wrapped with insulation one-time cast-forming, vacuum casting technique makes its pour mass inside not contain bubble, above measure has improved the dielectric strength of high voltage pulse formula transformer, guaranteed the even of end electric field, and saved installing space, it can be used safely under the environment of 110kv electric pressure.
