Abstract
The utility model relates to a 50kV high-voltage fixture for tests of electrical strength of insulating materials, which comprises an upper electrode and a lower electrode. The upper electrode is arranged in an upper protective cover, the lower electrode is disposed in a lower protective cover, the upper electrode and the lower electrode are connected with an experimental voltage output end of a withstanding voltage tester used for outputting 50kV high voltage through electrode leads, and are disposed on two sides of an experimental sample plate of an insulating material oppositely up and down, and arc preventive adhesive is arranged between a joint surface of the experimental sample plate with the upper protective cover and a joint surface of the experimental sample plate with the lower protective cover. In the 50kV high-voltage fixture, the testing electrodes are surrounded by the high-withstanding-voltage insulating material, the arc preventive adhesive is arranged at the joint surfaces so as to stop paths of arcs, and accordingly a test can be performed in air directly and cannot be affected due to ionization of the air. In addition, the 50kV high-voltage fixture realizes simple and reliable tests of electrical strength.
Description
Technical field
The utility model relates to the technical field of insulating material electrical strength experimental assembly, specifically is a kind of insulating material electrical strength experiment 50kV high pressure anchor clamps.
Background technology
In the check of electric product, the electrical strength test is one must do experiment, and it is to the insulating Design of examination electric product, and material is selected, product structure design, and the electrical safety quality of internal wiring and assembling link has important meaning.
Generally speaking, cause that the reason that the electrical strength test punctures has following several:
One, insulating Design is unreasonable.The design of electric clearance or creepage distance does not reach the requirement of standard, and the insulation system moulding is unreasonable, and the insulating material type selecting is unreasonable, often is ubiquitous owing to the test of the electrical strength of this type of reason punctures.Corrective action just must be changed from design concept.
Two, insulating material is bad.The influence that the product insulating material is subjected to high temperature, electric field and vibration makes insulation outmoded gradually, aging, performance depreciation, and the insulation course part has impurity, micro-pore, crack can cause that all the electrical strength test punctures.Corrective action must be selected good insulating material for use, and key position stops to use feed back.
Three, internal wiring is unreasonable.In internal wiring; circuit is answered rational deployment; wiring groove is answered smooth no sharp edge; in order to avoid the insulation of incised wound inner lead at all connection terminal positions, is used insulating sleeve; so that protection is reliable; the lead that suspends is used wire clamp and is fixed, prevent in transportation or when using vibration cause and come off, cause the electrical strength test to puncture.Corrective action must the strengthening process design.
Four, because the carelessness of assembly quality causes electrical strength to puncture.Electrical strength is a key property of insulating material, owing to need the trial voltage of several ten thousand volts, can't directly test under air condition, test unit need be immersed in the high pressure resistant oil and test, process of the test bothers very much and experimental result is subjected to the influence of hydraulic oil quality.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of simple in structure, insulating material electrical strength experiment of being suitable for significantly improving conventional efficient with 50kV high pressure anchor clamps.
For solving the problems of the technologies described above, the utility model provides a kind of insulating material electrical strength experiment 50kV high pressure anchor clamps, and it comprises: be located at top electrode and the bottom electrode of being located at down in the protective cover in the protective cover; Top electrode and bottom electrode link to each other by the experimental voltage output terminal of contact conductor with the pressure-resistant tester that is used to export the 50kV high-tension electricity; be located at the both sides of the experiment model of insulating material up and down in opposite directions when top electrode and bottom electrode use, and be provided with arc protection glue between the faying face of this experiment model and last protective cover and following protective cover.
Good effect of the present utility model: insulating material electrical strength experiment of the present utility model is with in the 50kV high pressure anchor clamps; anchor clamps use high withstand voltage insulating material that test electrode is surrounded; and the electric arc glue that goes out is used in the junction at experiment model and each protective cover; blocked the path of electric arc; feasible test can directly be carried out in air, and can not influence test because of air ionization.Make that carrying out the electrical strength test simply and reliably and has significantly improved conventional efficient.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
Fig. 1 is the structured flowchart that 50kV high pressure anchor clamps are used in the insulating material electrical strength experiment among the embodiment.
Embodiment
See Fig. 1, the insulating material electrical strength experiment of present embodiment comprises with 50kV high pressure anchor clamps: be located at top electrode 2 and the bottom electrode of being located at down in the protective cover 34 in the protective cover 1; Top electrode 2 and bottom electrode 4 link to each other by the experimental voltage output terminal of contact conductor 5 with the pressure-resistant tester 6 that is used to export the 50kV high-tension electricity; be located at experiment model 7 both sides of insulating material up and down in opposite directions when top electrode 2 and bottom electrode 4 use, and be provided with arc protection glue 8 between the faying face of this experiment model 7 and last protective cover 1 and following protective cover 3.
The foregoing description only is for the utility model example clearly is described, and is not to be qualification to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all embodiments.
