Description
Technical field
The invention belongs to transformer manufacture technology, specifically a kind of high frequency testing transformer that is applicable to the high frequency power transformer test.
Background technology
Along with the application of high-frequency electrostatic dedusting technology, and the development of the flexible power transmission and transformation technology of direct current, high-frequency power transformer output progressively enlarges.And the equipment such as withstand voltage test of high frequency power transformer also do not have supporting at present.Adopt special power frequency withstand test equipment to carry out delivery test at present, perhaps carry out the fictitious load operation and replace withstand voltage test.Power frequency withstand test can not test transformer and after putting into operation, be in withstand voltage under the high frequency state, and the high frequency overvoltage condition that fictitious load can not test transformer after putting into operation.So all can bring hidden danger to the use of transformer.
Summary of the invention
The purpose of this invention is to provide a kind of high frequency testing transformer, this transformer is the special-purpose transformer of a kind of high frequency power transformer withstand voltage test, and is simple in structure, easy to use, can satisfy the withstand voltage test requirement of various high frequency power transformers.
The objective of the invention is to realize through following technical scheme:
A kind of high frequency testing transformer is characterized in that: this transformer comprises iron core, winding, secondary staged winding, high-voltage connection and a low-voltage lead, and winding and secondary staged winding technique are on the iron core frame post; Unshakable in one's determination, winding and secondary staged winding are arranged in the oil tank of transformer, in oil tank of transformer, are marked with transformer oil; Outside high-voltage connection, be set with high-tension insulating bushing, outside low-voltage lead, be set with the low-voltage insulation sleeve pipe, and high-tension insulating bushing and low-voltage insulation sleeve pipe all are arranged on the oil tank of transformer and the oil tank of transformer outside, position.
Among the present invention, in oil tank of transformer, be provided with base, iron core is installed on the base.The present invention's ultra micro amorphous alloy material, single-phase horizontal type structure of adopting unshakable in one's determination.Winding of coiling and secondary staged winding are drawn high and low pressure input and output wiring on upper ledge post unshakable in one's determination, cool off and insulate with transformer oil.
This high frequency testing transformer capacity 50kVA, a rated voltage 0.4kV, secondary rated voltage 85kV, frequency 20～40kHz.The present invention is simple in structure, easy to use, can satisfy the withstand voltage test requirement of various high frequency power transformers.
