Description

A kind of coils of high-voltage transformers lead terminal
Technical field
The utility model relates to high-tension transformer technical fields, and in particular to a kind of coils of high-voltage transformers lead terminal.
Background technique
Transformer is the device for changing alternating voltage using the principle of electromagnetic induction, and main member includes primary coil, secondary Grade coil and iron core, according to the difference of the type of cooling, transformer can be divided into dry-type transformer and oil-immersed transformer.
Since transformer voltage is higher, if creepage distance not enough will lead to transformer pressure resistance and insulation distance not enough, Biggish leakage current even spark phenomenon can even occur when serious, be not able to satisfy the safety standard requirements of high-tension transformer, it is right The personal safety of technical staff will also result in potential threat.For the length for guaranteeing creepage distance, need dry-type transformer height The extended length of crimping circle lead terminal.However high pressure dry transformer at this stage is all made of high-tension coil one moulding by casting Technique, since the length of lead terminal is longer, when transformer high-voltage coil demoulding, it is easy to cause lead terminal to be broken, shadow Ring high-tension transformer high-tension coil qualification rate.
Utility model content
For the above-mentioned deficiency of the prior art, the utility model provides a kind of coils of high-voltage transformers lead terminal, with solution When certainly high-tension coil demoulds the technical issues of lead terminal easy fracture.The utility model structure is simple, easy to use, can reduce and draw Easy fracture phenomenon in line terminals manufacturing process.
A kind of coils of high-voltage transformers lead terminal, lead terminal include ontology and extension, described ontology one end and are become Depressor connection, body interior are equipped with tapped copper tip, and the extension includes creep distance slot and is arranged inside creep distance slot Copper bar, copper bar both ends expose, copper bar be equipped with external screw thread.
Further, the ontology is truncated cone-shaped structure, and one end that ontology is relatively large in diameter is connect with transformer.Truncated cone-shaped one Aspect can make the connection of ontology and transformer more firm, on the other hand also can reduce the degree of difficulty of demoulding.
Further, the length of the ontology is 3cm, and the length of the creep distance slot is 6cm.It adds creep distance slot and is meeting height Under the premise of voltage creep distance requires, the length of ontology is shortened, to promote the yield rate of ontology.
Further, 1cm is exposed at copper bar both ends respectively.Copper bar one end is threadedly coupled with ontology, and exposing 1cm can avoid Expose that size is too short is difficult to the problem of connecting;In use, the annulus terminal needs of electric wire cover on the other end of copper bar and pass through Nut is fixed, therefore the other end of copper bar needs to expose enough length.
Further, the creep distance slot is bellows-like structure.Creep distance is two conductions zero measured along insulating surface Shortest path between part or between conductive parts and equipment protection interface, creep distance slot is set as bellows-like structure can be effective Increase creepage distance.
Further, the creep distance slot is epoxy resin.The electrical insulation capability of epoxy resin is high, structural strength is big, sealing Property is good.
The beneficial effects of the utility model are that the utility model provides a kind of coils of high-voltage transformers lead terminal, Under the premise of meeting coil creep distance, shorten lead terminal ontology length, thus reduce be broken in ontology manufacturing process it is several Rate improves high-tension transformer high-tension coil product qualified rate, facilitates going on smoothly for transformer production.
