Abstract
The utility model discloses a pillar combined type insulator, including last metal accessories, lower metal accessories, cylindric plug and the outer full skirt of plug, the plug is epoxy glass fiber winding layer, the plug inner wall has the annular protruding structure of a plurality of. The longitudinal section of the protruding structure is square or rectangular or trapezoidal. The protruding structure is arranged as follows: the creepage distance in the vertical direction of the inner wall of the core rod is 1.5 to 2 times of the height of the core rod. The material of the protruding structure is epoxy resin. By adopting the scheme, the cylindrical core rod of the pillar composite insulator is internally provided with the plurality of annular protruding structures, so that the creepage distance of the inner wall of the core rod is effectively increased. In addition, the material of the protrusion structure is epoxy resin, and the protrusion structure can be well combined with the core rod. Therefore, compared with the prior art, the utility model discloses a pillar combined type insulator has that electrical property is good, production is convenient, low in manufacturing cost's advantage.
Description
Technical field
The utility model relates to a kind of pillar combined type insulator that is used for the high-tension electricity conveying equipment, belongs to power domain.
Background technology
Insulator is the necessary supply on high pressure, the ultrahigh voltage power conveying circuit, have only porcelain and glass insulator the earliest, to nineteen seventies, the high-temperature silicon disulfide rubber composite insulator at first comes out in Germany, compare with conventional insulators such as porcelain, glass, have that in light weight, intensity is big, advantages such as resistant dodges that ability is strong, maintenance and convenient transportation.In recent years, the composite line pillar insulator is also developing rapidly in China, but working voltage is restricted to 110kV and following mostly.
The existing high-tension electricity conveying circuit upper supporting column combined type insulator that is used for is by upper and lower metal-ware, and the full skirt of plug and mandrel outer constitutes, and plug generally has following two kinds.The one, adopt solid drawing of epoxy resin fiberglass to dial rod, owing to be subjected to the restriction of existing epoxy resin fiberglass technology, this pillar combined type insulator with solid mandrel production is difficult to satisfy the bending resistance of the above electric pressure isolating switch of 220kV pillar, antitorque requirement, and the pillar combined type insulator production cost of this solid mandrel production, transportation, installation cost are all than higher.Another kind is hollow plug, and in plug, fill sulfur hexafluoride gas, the pillar combined type insulator subject matter of this plug production is: often need detect sulfur hexafluoride gas content in the plug, caused the inconvenience in the use, and sulfur hexafluoride gas affects also to environment.
State Intellectual Property Office's on October 31st, 2007 disclosed " compound insulator with hollow bamboo-like pillar " (publication number: CN200969258), the disclosed post composite insulator of document is made of the full skirt of upper and lower metal-ware plug and mandrel outer, plug is made of ring element that links together and outer epoxy resin fiberglass winding layer thereof, and the ring element connects the back and forms hollow chamber.This kind insulator has good electric property, flexural strength and anti-torsional strength advantages of higher.But because in the generative process of insulator, the temperature of hollow chamber raises and causes the air expansion that hollow chamber is interior, gas can overflow from the junction of ring element, can influence the electric property and the mechanical performance of insulator like this, also there are deficiencies such as consumptive material is big, complex manufacturing technology in this in addition insulator in production process.
The utility model content
At above-mentioned situation, the problem that the utility model quasi-solution is determined provides the pillar combined type insulator of a kind of good electric property, convenient for production, low cost of manufacture.
For achieving the above object, the utility model is by the following technical solutions: a kind of pillar combined type insulator, comprise metal-ware, following metal-ware, the full skirt of plug cylindraceous and mandrel outer, described plug is the epoxy resin fiberglass winding layer, and described plug inwall has the raised structures of several ringlike.
The vertical section of raised structures is square or rectangle or trapezoidal.Being set to of described raised structures: the creepage distance of plug inwall vertical direction is 1.5-2 a times of plug height.The material of described raised structures is an epoxy resin.
Adopt such scheme, the plug cylindraceous inside of pillar combined type insulator of the present utility model is provided with the raised structures of several ringlike, being set to of described raised structures: the creepage distance of plug inwall vertical direction is 1.5-2 a times of plug height, effectively improved the creepage distance of plug inwall, and the quantity of inner process structure, width setting can be set according to the needs of producing and using.In addition, the material of raised structures is an epoxy resin, can good binding be arranged with plug.Therefore, compared with prior art, pillar combined type insulator of the present utility model has advantages such as good electric property, convenient for production, low cost of manufacture.
Description of drawings
Fig. 1 is the structural representation of pillar combined type insulator of the present utility model.
Among the figure: the last metal-ware of 1-, metal-ware under the 2-, 3-plug, 4-full skirt, 5-raised structures.
Embodiment
As shown in Figure 1, pillar combined type insulator of the present utility model, comprise metal-ware 1, following metal-ware 2, the full skirt 4 of plug 3 cylindraceous and mandrel outer, described plug 3 is the epoxy resin fiberglass winding layer, the pillar combined type insulator structure of said structure and prior art is similar, therefore no longer launches to describe.
Characteristics as the novel pillar combined type insulator of this usefulness are: described plug 3 inwalls have the raised structures 5 of several ringlike, and the vertical section of described raised structures 5 is square or rectangle or trapezoidal.Present embodiment is example (referring to Fig. 1) with the rectangle.The quantity of described raised structures 5, width setting can be set according to the needs of producing and using.In general, the setting of raised structures 5 make the creepage distance of plug 3 inwall vertical direction be plug 3 height 1.5-2 doubly, simultaneously, the material of raised structures 5 is an epoxy resin, can have good binding like this with plug.Make the interior wall energy of the novel pillar combined type insulator of this usefulness satisfy the requirement of the above electric pressure isolating switch of 220kV pillar plug 3 creepage distances like this, and bending resistance, antitorque requirement.
