Description
Technical field：
The present invention relates to the technical fields of transformer, being applied to dry-type transformer tap terminals more specifically to one kind
Isolation seat.
Background technology：
Transformer is the device for changing alternating voltage using electromagnetic induction principle.Traditional transformer can be divided into oil immersed type
Transformer, full-sealed transformer, combined transformer and dry-type transformer etc..Low capacity high voltage band tap on the market at present
The cast transformer of terminal, high-voltage outlet terminal and high-voltage tap terminals are typically placed in the both sides of transformer coil, in this way, objective
Family can be very inconvenient when using, and since there is an exposed terminal on transformer two sides, the safe distance of transformer also requires bigger.
It is influenced by extraneous factors such as weather in the reduced performance of insulating materials, as air humidity is big, cloudy intermittent drizzles in the rainy season in succession
The influence of the factors such as season, wet environment, charged metal position generate with insulating materials and are climbed along crust as water wave sample electric arc
Phenomenon, i.e. " creepage phenomenon ".To avoid creepage phenomenon from influencing the normal work of dry-type transformer, high-voltage charged body is led with another
Distance between electric body along body surface cannot be below certain value, this value is the minimum range of " creeping ", i.e. " creepage distance ".
The creepage distance of general 10kV is 250mm, and humid environment or the more place of dust will increase distance.However, in the prior art
Dry-type transformer of the low capacity high voltage with tap terminals in HV Terminal and high-voltage tap terminals between along body surface
Distance this minimum standard is but not achieved.To propose to be molded a rectangular-shaped insulation outside dry-type transformer tap terminals
Wall is molded a lofty insulation wall construction in transformer shell outer wall, needs transformer shell again to increase creepage distance
Die sinking, increases manufacturing cost, and pervious transformer shell cannot use and arrive this technology.
Invention content：
The purpose of the present invention and provides a kind of dry-type transformer that is applied to and taps end aiming at the deficiency of the prior art
The isolation seat of son facilitates and realizes installing and dismounting on transformer shell, varies without shape and the die sinking of transformer shell, can save
Cost-saving.
To achieve the above object, the technical solution adopted by the present invention is as follows：
A kind of isolation seat applied to dry-type transformer tap terminals includes the ceramic pedestal of " returning " font, ceramic pedestal
Lower end in there is flange, if forming the groove that font " is returned " in arterial highway on the bottom surface of flange, in the groove of ceramic pedestal grafting consolidate
Surely there is sealing ring, limiting plate is formed on the inside of ceramic pedestal, if forming the guide groove of arterial highway longitudinal direction, limiting plate on limiting plate
Front end face on against there is positioning sleeve, form connector sleeve on the rear end face of positioning sleeve, connector sleeve passes through the guide groove of limiting plate
Sleeve is fixed with stop collar, and the front side of the stop collar is equipped with block plate, is molded and transformer tap end on the rear end face of block plate
Son matched stud forms threaded hole on the front end face of block plate.
Preferably, the positioning sleeve is distributed in the guide groove of limiting plate both sides, the same guiding on limiting plate
Positioning sleeve there are two being set in slot.
Preferably, the positioning sleeve upper joint sleeve exposes the length of limiting plate rear end face less than limiting plate rear end face to flange
The distance of bottom surface.
Preferably, the stop collar is resisted against on the rear end face of limiting plate, and the thickness of stop collar is less than limiting plate rear end
Face to flange bottom distance.
Preferably, the groove on the ceramic pedestal is more than ceramic pedestal fovea superior at least provided with twice, the thickness of sealing ring
The depth of slot.
Preferably, the diameter of the block plate upper stud is less than the aperture of positioning sleeve endoporus.
Preferably, the diameter of the block plate is more than the aperture of positioning sleeve endoporus, and card slot is formed on the opposite outer wall of block plate.
The beneficial effects of the present invention are：
1, it is simple in structure, facilitates and realizes installing and dismounting on transformer shell, to vary without the shape of transformer shell
Shape, also there is no need to be molded again, so as to save cost.
2, it can be installed on the transformer shell for having completed installation, and electricity is climbed in the transformer reduction installed before realizing
Phenomenon.
3, it can be recycled from disassembly ＆ recycling on the transformer shell scrapped, and improve the utilization rate of resource.
