Abstract
The utility model discloses a transformer induced voltage experiment apparatus which comprises an elevating seat with three sleeve mounts where sleeve are installed, wherein lugs are fixed on the lower portions of two sleeve mounts through fasteners. The transformer induced voltage experiment apparatus is simple in structure, convenient for operation, and excellent in versatility, and effective lowers experimental cost. The transformer induced voltage experiment apparatus is applicable to a power transformer, which is three-phase and has a balanced winding and of which the group of Joining is YNyn0+d and the low voltage is higher than 35kV.
Description
Technical field
The utility model relates to the electronic transformer technical field, relates in particular to a kind of transformer induction voltage experimental provision.
Background technology
Along with the kind of power transformer product and increasing of quantity, wherein be with the balance winding, connection set is that the power transformer quantity of YNyn0+d also is being on the increase.When the low voltage voltage grade was higher than 35kV, induced test can't directly apply alternating voltage by transformer low voltage winding terminal, often needed to be powered up by the intermediate transformer of extra coupling, and not only test is complicated, operation inconvenience, has also increased experimentation cost.Therefore, seek a kind of simple in structure, easy to operate, highly versatile, the test unit that effectively reduces experimentation cost is significant.
The utility model content
The utility model purpose is exactly in order to remedy the defective of prior art, transformer induction voltage experimental provision a kind of simple in structure, easy to operate, highly versatile to be provided.
The utility model is achieved through the following technical solutions:
A kind of transformer induction voltage experimental provision includes the seat that raises, and on the described rising seat three sleeve pipe mount pads is arranged, and on the sleeve pipe mount pad sleeve pipe is installed, and wherein fixedly there is lug plate two sleeve pipe mount pad belows by securing member.
Described securing member includes bolt GB5783-M12, nut GB6170-M12, packing ring and dish spring ZL.
Described sleeve pipe adopts 20kV electric pressure sleeve pipe.
The utility model has the advantages that: the utility model is simple in structure, and is easy to operate, and highly versatile effectively reduces experimentation cost, is applicable to three facies tract balance windings, and connection set is YNyn0+d, and low voltage voltage is higher than the power transformer of 35kV grade.
