Abstract
The utility model belongs to a radiator of a porcelain pole circuit breaker, which comprises a porcelain sleeve, an upper grading ring, a lower grading ring, an upper wire outlet terminal, a lower wire outlet terminal, an upper flange and a lower flange. Radiators are arranged on the upper flange and the lower flange. Each radiator is formed by a radiating base, radiating fins and fixing holes. The radiating base is in an annular shape and is provided with the fixing holes. A plurality of radiating fins are distributed at one side of the radiating base at intervals. Grooves for horizontally blocking the protrusions on the upper flange or the lower flange are arranged at the other side of the radiating base. The radiator which is added on the radiator of the porcelain pole circuit breaker can improve the performance of radiating outwards of the current system. The radiator of the porcelain pole circuit breaker has the advantages of simple structure, stable performance, quick radiation, good using effect and convenience in adjusting.
Description
Technical field
The utility model belongs to a kind of porcelain knob breaker radiator.
Background technology
Along with the high voltage switchgear trend of miniaturization and high parameterization day by day, electric power system is also more and more higher to the requirement of high voltage switchgear reliability.This just has higher requirement to the through-current capability of high-voltage switch gear major loop.Generally require the specified through-current capability of 252kV porcelain knob breaker will reach 4000A even higher 5000A on the market now.Want to make high voltage switchgear on original size basis, improve through-current capability, just need reduce system's heating and externally dispel the heat with the increase through-flow system.
Porcelain knob breaker, leading electric system all is enclosed in the interrupting porcelain insulator that is filled with SF6 gas.Because the restriction of insulator inner space makes and compares with potting breaker that SF6 tolerance is less, thermal capacity is less, radiating condition is relatively poor, and causes circuit breaker internal temperature rise point temperature rise value too high.Porcelain knob breaker leading body loop is the outlet seat supports by the insulator upper and lower side, and the heat conductivility of insulator itself is very poor, and the insulator outer surface is difficult to outwards distribute a large amount of heat, so be to conduct and thermal radiation with the main heat transfer type in inside.And conduction is wherein occupied an leading position.Inner conductor, electrically contact generation heat mainly with conduction mode, be transmitted on outlet flange, the outlet end plate and distribute to the external world.The method of improving its heat dispersion commonly used is to increase the surface area of going up the lower wire end plate.But the surface area of lower wire end plate is subjected to the volume size and the criteria limit of lower uniform pressure ring in the increase, and the area that increases is limited, and especially big with last outlet end plate contact area, the thermal resistance of heat transfer is little.
Summary of the invention
The purpose of this utility model is a kind of porcelain knob breaker radiator of design, on porcelain knob breaker, set up heat abstractor, can increase the externally performance of heat radiation of through-flow system, have simple in structure, stable performance, the advantage that rapid heat dissipation and result of use are good easy to adjust.
For this reason, the utility model mainly is made up of insulator, last grading ring, lower uniform pressure ring, last leading-out terminal, lower wire end, upper flange plate and lower flange, on upper flange plate and lower flange, be provided with radiator, described radiator is made of heat dissipation base, radiating fin and fixing hole, it is circular that heat dissipation base is, heat dissipation base is provided with fixing hole, numerous radiating fins of spacing distance distribution on one side of heat dissipation base, the another side of heat dissipation base are provided with to keep supplying and protrude the groove that the position card crouches on ring flange or the lower flange.The diameter of described radiator is identical with upper flange plate or lower flange diameter.Said structure has reached the purpose of this utility model.
The utility model is being set up heat abstractor on porcelain knob breaker, can increase the externally performance of heat radiation of through-flow system, have simple in structure, stable performance, the advantage that rapid heat dissipation and result of use are good easy to adjust.

Specific embodiments
As shown in Figures 1 to 4, a kind of porcelain knob breaker radiator mainly is made up of insulator 5, last grading ring 1, lower uniform pressure ring 6, last leading-out terminal 3, lower wire end 7, upper flange plate 4 and lower flange 8.The utility model is provided with radiator 2 on upper flange plate and lower flange.Described radiator is made of heat dissipation base 23, radiating fin 21 and fixing hole 22.
It is circular that heat dissipation base is, and heat dissipation base is provided with fixing hole, and the effect of fixing hole is to wear screw radiator can fixedly be become one with upper flange plate and lower flange easily.Numerous radiating fins of spacing distance distribution on one side of heat dissipation base, two adjacent radiating fin spacers are 10mm～80mm, the thick 4mm of fin, high 50mm, long 80mm, about 100～200 an of week.Fin can make or the area of dissipation at lower wire end plate place increases about 4～5 times.The another side of heat dissipation base is provided with to keep supplying on ring flange or the lower flange protrudes the groove 24 that the position card crouches, and makes heat dissipation base fitted tightly with corresponding upper flange plate or lower flange with the side to be fixed as one.The diameter of described radiator is identical with upper flange plate or lower flange diameter.Radiator is by casting aluminium material integral casting forming (can be better with the effect of copper), can plate one deck tin in spreader surface with out of doors the time, is used for corrosion protection, guarantees the performance of its corrosion-resistant high life.
During use, only need radiator is fixed as one with closely connected the closing of the upper flange plate and the lower flange outside respectively with screw.System's heating of being conducted the porcelain knob breaker that by upper and lower ring flange can be passed through the effective bulk storage of radiator.Two radiators all are in respectively within the shield ranges of upper and lower grading ring, and the adverse effect that cusped edge wedge angle of fin produces above it is all eliminated by upper and lower grading ring shielding, substantially can be not influential to the external insulation of insulator.Install the heat dispersion that radiator must promote product systems greatly additional, through-current capability also can improve thereupon.
In a word, the utility model is set up heat abstractor at porcelain knob breaker, can increase the externally performance of heat radiation of through-flow system, have simple in structure, stable performance, the advantage that rapid heat dissipation and result of use are good easy to adjust.
