Description

A kind of direct current transportation porcelain bottle insulators

Technical field

The utility model relates to field of electrical equipment more particularly to a kind of direct current transportation porcelain bottle insulators.

Background technique

Porcelain bottle insulators are widely applied in alternating current power grid, and porcelain bottle insulators be used to high-voltage line being fixed on high-voltage line On electric pole, porcelain vase primarily serves the effect of fixed high-voltage line and insulation.DC distribution technology is the development trend of the following power grid, it There is many advantages, such as power generation of support distribution formula and energy conservation.If but D.C. high voltage transmission directly uses the porcelain bottle insulators of alternating current There can be problem, since direct-current electrical field direction is fixed, ionization, which can occur, for the high-voltage line to contact with each other under electric field action makes Metal ion is transferred to porcelain vase surface, and porcelain vase surface will cover one layer of conductive metal layer for a long time, to cannot play Insulating effect.

Summary of the invention

Technical problem to be solved by the utility model is: a kind of direct current transportation porcelain bottle insulators are provided, to solve existing porcelain The problem of bottle insulator cannot play insulating effect for direct current transportation.

The technical solution of the utility model is: a kind of direct current transportation porcelain bottle insulators, including porcelain vase ontology and porcelain vase ontology The groove that top opens up, the fluted external surface are equipped with plastic layer.

Further, the plastic layer stretches out groove notch 30cm.

Further, the porcelain vase body lower part is equipped at least one isolation ring, table in the prominent porcelain vase body lower part of isolation ring Face.

Further, the isolation ring surface is laid with hydrophobic material.

Further, the hydrophobic material is polytetrafluoroethylene (PTFE).

The beneficial effects of the utility model are:

Compared with prior art, the utility model avoids high pressure by the way that plastic layer is arranged in the groove of installation high-voltage line Line directly contacts with porcelain vase and generates galvanic interaction.The utility model structure is simple, is easy to pass through existing alternating current porcelain insulator Son transformation, transmits electricity especially suitable for direct current.

In figure: 1 porcelain vase ontology, 2 grooves, 3 high-voltage lines, 4 isolation rings, 5 hydrophobic materials, 6 plastic layers.

Specific embodiment

With reference to the accompanying drawing and utility model is described further in specific embodiment:

Referring to figs. 1 to Fig. 3, a kind of direct current transportation porcelain bottle insulators, including porcelain vase ontology 1 and 1 top of porcelain vase ontology open up Groove 2,2 outer surface of groove be equipped with plastic layer 6.When two object rubs mutuallies, wherein must there is an object to lose Some electronics, another object obtain extra electronics.Such as with glass bar with silk friction, some electronics transfers of glass bar are arrived On silk, glass bar is positively charged because losing electronics, silk negative electricity such as band due to obtaining electronics.With rubber bar with fur friction, In some electronics transfers to sticking plaster of fur, fur is positively charged, rubber-plastic with equivalent negative electricity.This is because plastics are to electricity The constraint ability of son is stronger, and glass is weaker to the constraint ability of electronics.Since there are plastic layers with porcelain vase ontology 1 for high-voltage line 3 6, the electronics constraint ability of plastic layer 6 is stronger, will mitigate the ionization of high-voltage line 3, thus due to electricity when avoiding direct current transportation Metal ion from effect generation is the problem of porcelain bottle insulators surface forms current conducting layer.

Further, the plastic layer 6 stretches out 2 notch 30cm of groove.The 30cm of stretching can increase high-voltage line 3 and porcelain vase 1 distance of ontology reduces the ionization of high direct voltage line 3 at a dc voltage.

Further, 1 lower part of porcelain vase ontology is equipped at least one isolation ring 4, prominent 1 lower part of porcelain vase ontology of isolation ring 4 Inner surface.Isolation ring 4 plays the role of stopping water two porcelain bottle insulators of connection that two porcelain bottle insulators is caused to be connected, even if in rain It, since the presence of isolation ring is more difficult from but also being connected between insulator.

Further, 4 surface of isolation ring is laid with hydrophobic material 5.Hydrophobic material 5 can make to be adhered to porcelain bottle insulators The water of inner surface is detached from rapidly porcelain bottle insulators inner surface, avoids water in porcelain insulator sub-surface aggregating.

Further, the hydrophobic material 5 is polytetrafluoroethylene (PTFE).Polytetrafluoroethylene (PTFE) has good hydrophobicity, and antiacid Alkali resistant is cheap.

It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined Assert that the specific implementation of the utility model is only limited to these instructions.For the ordinary skill of the utility model technical field For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard To belong to the protection scope of the utility model.
