Abstract
Provided is a high-repeatability standard along surface discharge model device which is characterized by comprising an organic glass circular tube (5). The upper and lower ends of the circular tube (5) are respectively sealed by upper and lower end covers (4,9). The upper periphery of the upper end cover (4) is provided with ventilation holes (2), the middle part is connected with a high-voltage electrode (3) via threads, and a tungsten pin (6) is arranged below the high-voltage electrode. The middle of the lower end cover is provided with a grounding electrode (8). A crystal ball (7) is pasted on the upper surface of the grounding electrode by pouring glue. A discharge gap is arranged between the tungsten pin and the crystal ball. The actual measurement indicates that the discharge model device is low in discharge capacity, stable in discharge and high in repeatability.
Description
Technical field
The utility model relates to the gas discharge device in a kind of high-voltage insulation technique field.
Background technology
GIS partial-discharge ultrahigh-frequency on-line monitoring system need to be according to the various electric discharge type development in GIS inside standard discharging model, the particularly demarcation of on-the-spot on-line monitoring system, an amplitude stability, and the standard discharge source that emissive power is constant is indispensable device.The problems such as existing creeping discharge modelling is more coarse, there is no unified technical standard, and exists discharge capacity larger, discharges stable not, and repeatability is bad.
Utility model content
Technical problem to be solved in the utility model, is just to provide a kind of high duplication standard creeping discharge model equipment.
Solve the problems of the technologies described above, the technical solution adopted in the utility model is as follows:
A kind of high duplication standard creeping discharge model equipment, it is characterized in that: comprise an organic glass pipe 5, pipe Shang Xia 5 two ends use respectively, bottom end cover 4,9 sealing, upper end cover 4 upper peripheries have air hole 2, middle for the high-field electrode 3 that has been threaded, the below of high-field electrode is tungsten pin 4; In the middle of bottom end cover, be provided with earthing pole, above earthing pole, with encapsulating, be bonded with crystal ball; Between tungsten pin and crystal ball, leave discharging gap.
Described upper and lower end cap 4,9 use screws 1 are fixed on pipe wall.
Beneficial effect: it is prototype that this model equipment be take the defect fault of actual field, adopts pin-spherical structure, and material adopts respectively tungsten pin and crystal ball, has a small unsettled setting (not contacting between pin, ball) between same hour hands-ball.The innovative point of this scheme is: pin-spherical structure trigger position that makes to discharge is fixed, and retains the development that slight void contributes to electric discharge between pin and ball, and creeping discharge is more easily occurred; Use tungsten pin and crystal ball to guarantee that the damaged condition of electrode and dielectric surface is very low, realized to greatest extent the repeatability of electric discharge; Simultaneously ball shape structure makes can alive dynamic range very greatly, and discharge capacity is very little and be difficult for puncturing.
Actual measurement shows that this creeping discharge model discharge capacity is little, discharge stability, favorable repeatability.
