Abstract
The invention discloses a voltage-withstanding testing jig of a vertical transformer, wherein the voltage-withstanding testing jig comprises a fixture body and is characterized in that the fixture body comprises a sample bracket for simultaneously putting a plurality of transformers to be tested; a plurality of grooves the same as the transformers to be tested in width are arranged on the sample bracket; a first contact device and a second contact device for being contacted with detection points of the transformers to be tested are arranged on the fixture body and respectively and symmetrically arranged at two sides of the sample bracket; a plurality of sets of thimbles for being simultaneously contacted with the detection points of the transformers are arranged on the first contact device and the second contact device; and the other ends of the thimbles are respectively connected with a detection apparatus through a power line. The voltage-withstanding testing jig of the vertical transformer provided by the invention has the advantages of being simple in structure and convenient for use and is capable of simultaneously testing a plurality of transformers; simultaneously, a plurality of indexes can be tested; and the testing efficiency is increased.
Description
Technical field
The present invention relates to a kind of vertical transformer pressure resistant test tool.
Background technology
Transformer is the device of conversion alternating voltage, exchange current and impedance, when being connected with alternating current in the elementary coil, just produces exchange flux in the iron core (or magnetic core), makes and induces voltage (or electric current) in the secondary coil.Transformer is made up of iron core (or magnetic core) and coil, and coil has two or more windings, and the winding that wherein connects power supply is primary coil, and remaining winding is secondary coil.
Transformer withstand voltage test (executing high-potting outward) mainly is whether the major insulation of check transformer is qualified, is exactly between primary coil, the secondary coil, the insulation status between they and iron core, the shell.If defective, not only entail dangers to transformer itself and other continuous electric tools damage, and also can cause danger to the equipment and the personnel of electricity consumption.
Withstand voltage test is to add certain ac high voltage with power frequency testing transformer, continues one minute, if insulation does not puncture or leakage current is no more than certain value, is exactly qualified.
Existing transformer pressure resistant test tool generally only is provided with two test contact pens; Each transformer all will be tested respectively three times; Between the primary coil of transformer, the secondary coil, between primary coil and the iron core and carry out voltage-withstand test between secondary coil and the iron core; Troublesome poeration, testing efficiency is low.
Summary of the invention
Goal of the invention: in order to overcome the deficiency that exists in the prior art, the present invention provides a kind of vertical transformer pressure resistant test tool, and is simple in structure, easy to use, can test a plurality of transformers simultaneously, tests a plurality of indexs simultaneously, improves testing efficiency.
Technical scheme: for solving the problems of the technologies described above, the technical scheme that the present invention adopts is:
Vertical transformer pressure resistant test tool comprises chuck body, it is characterized in that: said chuck body comprises the sample holder that is used for placing simultaneously a plurality of transformers to be tested, and said sample holder is provided with and a plurality of grooves of transformer to be tested with width.
Said chuck body is provided with first contact device and second contact device that is used for contact measured transformer check point, and symmetry is positioned at the sample holder both sides respectively; Said first contact device is provided with the many groups of thimbles that contact the transformer check point simultaneously with second contact device, and the other end of said thimble all is connected with detecting instrument through power lead respectively.
Said chuck body comprises a base plate, and said first contact device is fixedly installed on the base plate, and second contact device passes the cross bar and corresponding the laterally arranging of first contact device that is fixedly connected with first contact device with sample holder.
Said chuck body also comprises and being used for compressing the thrust unit that first contact device and second contact device make thimble contact with transformer.
Said cross bar is respectively arranged with the spring that is used to cushion with balance thrust between first contact device and sample holder and second contact device and sample holder.
Beneficial effect: vertical transformer pressure resistant test tool provided by the invention, simple in structure, easy to use, can test a plurality of transformers simultaneously, test a plurality of indexs simultaneously, improve testing efficiency.
