A kind of novel high voltage reactor
This utility model relates to a kind of high voltage reactor, a kind of novel high voltage reactor, belongs to electric component.
The lead-out terminal of existing high voltage reactor all must use sleeve pipe to export, and to solve the Insulation Problems between HV Terminal and iron-clad, the highest sleeve pipe of voltage is the longest, is not suitable for often moving occasion and uses.
Utility model content:
The purpose of this utility model is: propose a kind of novel high voltage reactor.
Implementation method of the present utility model: the iron core of this reactor is quadrilateral structure, air gap is left on the stem stem of two of which horizontal sides, being wound with the coil of horizontal positioned on two stem stems have air gap respectively, it is equipotential link with iron core that the bottom of upper and lower two coils is started after connection；Unshakable in one's determination be placed in metallic oil tank for entirety with coil fastening, at the bottom of unshakable in one's determination and metallic oil tank between have insulating supporting cushion block, iron core and coil entirety are fixed being placed in metallic oil tank base plate；The metal cover board of metallic oil tank is connected with metallic oil tank structure by epoxy insulation cylinder, and the metal cover board of metallic oil tank and metallic oil tank are electric insulation structure；Epoxy insulation cylinder is consistent with the connection cross sectional shape of metallic oil tank, and metal cover board is that flange seal is connected with epoxy insulation cylinder, and epoxy insulation cylinder is that flange seal is connected with metallic oil tank；Upper coil tail head is connected with metal cover board, and for high voltage reactor high-voltage output connector, the tail head of lower planar coil is by low pressure lead-out wire insulator or is connected with metallic oil tank, as reactor low-voltage end connector.
In this utility model: the core construction of reactor is laminated core or rewinding material.
In this utility model: the cross sectional shape of metallic oil tank and epoxy insulation cylinder is circular or square or rectangle.
In this utility model: the corner of the square or square-section of metallic oil tank and epoxy insulation cylinder is right angle or arc-shaped transitional surface.
In this utility model: circular or square or rectangular metal fuel tank lateral surface peripheral device has one or more fin.
In this utility model: epoxy insulation tube outer surface has one or more full skirt.

Detailed description of the invention
Accompanying drawing 1 and Fig. 2 is to have expressed a kind of embodiment of the present utility model, which discloses basic structure of the present utility model without limitation, below in conjunction with legend, this utility model is described further: for reducing iron core vibrations noise, coil, iron core, air gap iron-core and air gap cushion block pass through securing member, fully fasten；After coil and fastening unshakable in one's determination are for entirety, being placed on core inductance lip block, insulating supporting cushion block to meet the insulation of current potential unshakable in one's determination；Reactor high-voltage terminal utilizes the isolation support of epoxy insulation cylinder to accomplish with the insulation of metallic oil tank.
The utility model has the advantage of: solve the difficult problem of lead-out process without sleeve pipe of high voltage reactor, in fields such as extra high voltage network and the mobile high voltage reactors tested, there is wide application prospect.
This utility model is open as above with basic embodiment, in the extension without departing from this utility model technological thought, equally within claims of the present utility model.
