Abstract

The utility model discloses a voltage withstand testing jig of a horizontal transformer, which comprises a fixture body and is characterized in that the fixture body comprises an intermediate installation plate for placement of a plurality of transformers to be tested; a plurality of grooves, the lengths of which are the same to that of the horizontal transformers to be tested, are arranged on the intermediate installation plate; probe sheets for being contacted with an iron core are arranged at the positions of baffles at two sides of the groove; the probe sheets are connected with a detection apparatus through power lines; a first contact device and a second contact device for being contacted with the detection points of the transformers to be tested are arranged on the fixture body and are respectively and symmetrically arranged at two sides of the intermediate installation plate; a plurality of sets of ejector pins in a row, which are simultaneously contacted with the detection points of transformer coil pins, are arranged on the first contact device and the second contact device; and the other ends of the ejector pins are connected with the detection apparatus through the power lines respectively. The voltage withstand testing jig of the horizontal transformer disclosed by the utility model is simple in structure and convenient for use and is capable of testing a plurality of transformers and a plurality of indexes simultaneously, therefore, the testing efficiency is increased.

Description

The horizontal type transformer pressure resistant test tool
Technical field
The utility model relates to a kind of horizontal type 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 comprised of iron core (or magnetic core) and coil, and coil has two or more windings, wherein connects the winding of power supply 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, also can be to equipment and personnel's cause danger 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 voltage-withstand test tool generally only is provided with two test contact pens, each transformer 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.
And for horizontal type transformer, can't contact iron core with probe at side because side is surrounded by adhesive plaster.
The utility model content
The utility model purpose: in order to overcome the deficiencies in the prior art, the utility model provides a kind of horizontal type transformer pressure resistant test tool, and is simple in structure, easy to use, can test simultaneously a plurality of transformers, tests simultaneously a plurality of indexs, improves testing efficiency.
Technical scheme: for solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The horizontal type transformer pressure resistant test tool, comprise chuck body, it is characterized in that: described chuck body comprises for the middle installing plate of placing simultaneously a plurality of transformers to be tested, is provided with and a plurality of grooves of horizontal type transformer to be tested with length on the described middle installing plate; The baffle position on described groove both sides is provided with the spy sheet for the contact iron core, and described spy sheet is connected with detecting instrument by power lead.
Be provided with the first contact device and the second contact device for contact measured transformer check point on the described chuck body, installing plate both sides in the middle of symmetrical being positioned at respectively, be provided with the many groups of row's thimbles that contact simultaneously transformer coil pin check point on described the first contact device and the second contact device, the other end of described thimble all is connected with detecting instrument by power lead respectively.
Described spy sheet is fixed by screws on the middle installing plate.
Beneficial effect: the horizontal type transformer pressure resistant test tool that the utility model provides, simple in structure, easy to use, can test simultaneously a plurality of transformers, test simultaneously a plurality of indexs, improve testing efficiency.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Among the figure: installing plate in the middle of 1; 2 grooves; 3 visit sheet; 4 first contact devices; 5 second contact devices; 6 thimbles.
Embodiment
Below in conjunction with accompanying drawing the utility model is further described.
Be illustrated in figure 1 as a kind of horizontal type transformer pressure resistant test tool, comprise chuck body, described chuck body comprises for the middle installing plate 1 of placing simultaneously a plurality of transformers to be tested, is provided with and a plurality of grooves 2 of horizontal type transformer to be tested with length on the described middle installing plate; The baffle position on described groove 2 both sides is provided with the spy sheet 10 for the contact iron core; Visiting sheet 3 is fixed by screws on the middle installing plate 1; Visiting sheet 3 is connected with detecting instrument by power lead; Be provided with the first contact device 4 and the second contact device 5 for contact measured transformer check point on the chuck body, installing plate both sides in the middle of symmetrical being positioned at respectively, be provided with the many groups of row's thimbles 6 that contact simultaneously transformer coil pin check point on the first contact device 4 and the second contact device 5, the other end of thimble 6 is all respectively by the power lead (not shown) that is connected with detecting instrument.
The above only is preferred implementation of the present utility model; be noted that for those skilled in the art; under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
