Abstract
The utility model discloses a circuit pin type porcelain insulator, including fitting pin, porcelain spare, hot -galvanize steel foot and iron core cap, porcelain spare sets up as the three consecutive open umbrella structure who describes that is along vertical direction, and the iron core cap is installed at the top of porcelain spare, and hot -galvanize steel foot is installed to the lower part of porcelain spare, and inside porcelain spare was inserted to the upper end of hot -galvanize steel foot, the fitting pin was installed to the lower extreme of hot -galvanize steel foot, porcelain spare is provided with the gasket with hot -galvanize steel foot upper end contacting area, through the bonding of cement river sand glue layer between porcelain spare and the hot -galvanize steel foot, install the spring shim between hot -galvanize steel foot and the fitting pin, the utility model discloses simple structure, reasonable in design, heat dispersion is better, self -cleaning, and the nature is stronger, creepage distance is big, mechanical properties good, the electric property is good, can effectively ensure transmission line's safe operation.
Description
Technical field
The utility model relates to a kind of electric transmission line isolator, specifically a kind of line pin-type porcelain insulator.
Background technology
The P-10T line pin-type porcelain insulator of prior art all can not meet growing transmission line requirement on heat dispersion, creepage distance and self-cleaning property, needs the performance strengthening its each side, to increase the safety in operation of transmission line.
Utility model content
The purpose of this utility model is to provide the line pin-type porcelain insulator that a kind of thermal diffusivity is good, creepage distance long, self-cleaning is stronger, to solve the problem proposed in above-mentioned background technology.
For achieving the above object, the utility model provides following technical scheme:
A kind of line pin-type porcelain insulator, comprise locking pin, porcelain piece, hot-galvanized steel pin and core cap, described porcelain piece is vertically set to three beveled structures in open shape be connected successively, the top of porcelain piece is provided with core cap, the bottom of porcelain piece is provided with hot-galvanized steel pin, porcelain piece inside is inserted in the upper end of hot-galvanized steel pin, and the lower end of hot-galvanized steel pin is provided with locking pin; Described porcelain piece and hot-galvanized steel pin upper-end contact position are provided with pad, bonded, be provided with spring shim between described hot-galvanized steel pin and locking pin between porcelain piece and hot-galvanized steel pin by cement river sand glue layer.
As further program of the utility model: the total height of described porcelain piece and hot-galvanized steel pin is 133mm, the external diameter of porcelain piece is 140mm, and creepage distance is 255mm.
Compared with prior art, the beneficial effects of the utility model are: the utility model structure is simple, reasonable in design, compared with the P-10T line pin-type porcelain insulator of prior art, the porcelain piece of this practicality is set to three umbrellas styles of opening, and heat dispersion is better, and self-cleaning is stronger; Creepage distance is 255mm, and creepage distance adds about 25%; Mechanical bend tolerance load >=2.0KN, porcelain piece bending failure load >=10.6KN, mechanical performance is better; Electric property also improves greatly, lightning impulse withstand voltage >=90KV, one minute power frequency wet withstand voltage >=40KV, particularly frequency breakdown voltage is 130KV, far above the 95KV of P-10T line pin-type porcelain insulator in prior art, improve nearly 35%, the effective guarantee safe operation of transmission line.
