Description
Technical field
The utility model relates to a kind of creeping discharge model equipment, especially a kind of creeping discharge model equipment changing degree of combining closely between electrode and medium.
Background technology
Creeping discharge refers to the electric discharge phenomena that the interphase of the different medium such as solid (or liquid) and gas (or liquid) in flashover electric field occurs.Creeping discharge develops into perfoliate puncturing between electrode and is called flashover.The electric discharge of insulator is the creeping discharge phenomenon in modal a kind of gas.Because the voltage breakdown of the voltage's distribiuting Bu Jun Yun ﹐ edge flashing voltage ratio gas on dielectric interface or solid individualism is all low.Spark in flashover passage or electric arc make insulating surface local overheating cause charing, and damaging surface insulate.
In order to improve the edge flashing voltage of insulation system, General Requirements electrode and medium-tight combine, to reduce between electrode and medium due to not closely sealed and air gap that is that leave.But this degree of combining closely generally does not have quantitative target, be also difficult to detect.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of creeping discharge model equipment changing degree of combining closely between electrode and medium, and it can quantitative measurment and study degree of combining closely between difform electrode and different medium easily.

Preferably, described dielectric-slab 5 can be glass plate, ceramic wafer or epoxy resin board.
Preferably, described battery lead plate 1 is tubular relative at the bottom of cylinder with battery lead plate 3.
When using device of the present utility model, by rotating metallic Rotatable base 6 and metal rotatable portion 7, the degree of combining closely between adjustable pin electrode 403 and dielectric-slab 5, and the deformation causing spring 402.The degree of known spring deformation and the elasticity coefficient of spring, can calculate the pressure suffered by pin electrode 403, and can using this pressure as the index of combining closely between electrode and medium.
Beneficial effect:
1. use spring needle, by the pressure changing the deformation of spring and can change and between surveyingpin electrode and medium, thus easily change the degree of combining closely between pin electrode and medium;
2. the electrode part in the spring needle electrode tube described in can be changed, and can more easily observe dissimilar pin electrode, the development of creeping discharge under degree of combining closely as different between electrode and medium in tylostyle electrode, Tip-headed needle electrode etc.;
3. the spring section in the spring needle electrode tube described in can be replaced with the spring of different elasticity coefficient, can adjustable elastic coefficient, thus the impact of degree of combining closely opposite creeping discharge that can be more easily different with medium with more fully Electrode;
4. because the elasticity coefficient of used spring is known, and can the deformation of measuring spring, easily can calculate the pressure suffered by electrode; Electrode pressure can be used as the index of combining closely between electrode and medium, compensate for the blank of prior art;
5. Rotatable base and dielectric-slab are separate design, rotate the height of the adjustable dielectric-slab 5 of Rotatable base 6, upwards back-pressure pin electrode cylinder, cause spring deformation, but dielectric-slab can not be caused to rotate, also would not cause surface of contact change in location and the wearing and tearing of pin electrode and dielectric-slab, thus holding electrode and medium surface state is stable.
