Abstract
In the invention, the insulator comprises core rod, umbrella skirt outside the core rod and metal ends at two ends of core rod. Inner umbrella skirt is added to umbrella skirt, and metal coating layer covers surface of inner umbrella skirt. The inner umbrella skirt is covered by outer umbrella skirt. Inner umbrella skirt increases metal part of composite insulator, improving evenness of electric field, increasing mechanical strength of umbrella skirt, reducing illegible flashover of composite insulator, increasing stress part of core rod, and mechanical strength of core rod, enhancing external insulation capability of insulator so as to add backup protection of creep for external umbrella skirt.
Description
Technical field the present invention relates to the used insulator of a kind of ultra-high-tension power transmission line
The effect of background technology insulator is that current potential conductor inequality is separated, and not allowing has electric current to pass through between the conductor, to keep current potentials different between them.Insulator is generally made by the high insulating material of resistance, can isolate conductor charged or different potentials with this material, and electric current can be circulated by certain direction.
According to the difference of insulating material, insulator can be divided into porcelain insulator, glass insulator and composite insulator three major types.Composite insulator is made of plug, full skirt and metal termination three parts.The full skirt of composite insulator is an insulator external insulation part, its role is to provide leakage distance of necessity and the invasion and attack that the protection plug exempts from atmospheric environment, so that insulator keeps sufficiently high pollution flashover voltage and insulation property reliably and with long-term.
The basic demand of full skirt condition of work and full skirt material is:
1, gas performance requirement
What insulator bore when normally moving is operating voltage, but, because a variety of causes, the phenomenon that raises in short-term appears in voltage in the electric power system sometimes, promptly produces overvoltage, though superpotential action time is very short, but superpotential numerical value substantially exceeds normal working voltage, thereby the destruction of easily causing insulation, so insulator except that the continuous action that should be able to tolerate operating voltage, also must can tolerate superpotential effect;
High-tension insulator is in operation usually also can be subjected to the effect of various filths and moist atmosphere condition, and for example therefore mist, drizzle, clog snow, ice, condensation, industrial filth and salt fog etc. require the full skirt of insulator should have enough durability against pollutions;
Under disadvantageous condition, local arc may appear in the surface of insulator, and under its effect, might be burnt and residual trace occur conducting electricity in the surface, reduced the electrical strength of insulator, so require the full skirt of insulator should have very high anti-electric arc ability;
1, hot property requirement
Insulating material all has definite temperature capacity, and when variations in temperature, insulating material inside will produce very big stress, causes insulator breakdown, therefore requires the full skirt of insulator should have the ability of the cold-resistant hot sudden turn of events;
2, learn stability
The insulator of working out of doors should be able to withstand long term exposure the erosion of atmospheric factors such as sunshine, wind sand, misty rain, ice and snow, at the insulator of plateau work, must consider the influence of the change of air pressure, temperature, humidity to insulating material.The insulator of under specific condition, working, for example at the environment that contains the organic chemistry etchant gas or at the insulator of humid tropics environmental work, also should be as the case may be, guarantee that it has enough tolerances to various adverse factors, so, should require enough chemical stabilities to the full skirt of insulator.
Summary of the invention the objective of the invention is at above-mentioned present situation; aim to provide a kind of Electric Field Distribution evenly, plug, the mechanical strength height of full skirt, the unidentified flashover that can reduce composite insulator, external insulation ability be strong, aging or damage has the composite insulator that interior umbrella skirt construction is arranged of backup protection effect to external shed.
The implementation of the object of the invention is, the composite insulator of interior umbrella skirt construction is arranged, and is made of the full skirt of plug 1, mandrel outer and the metal termination at plug two ends.The interior full skirt 3 that is formed by organic resin material is arranged on the plug, and interior full skirt surface coverage has metal coating 4, the peripheral external shed 2 of interior full skirt.
Full skirt of the present invention is made of inside and outside full skirt, adopts the present invention, and following advantage is arranged:
1, traditional composite insulator is single structure, only there is the gold utensil termination at two up and down, they and middle plug and the common interelectrode capacitance that constitutes of full skirt are much smaller than the porcelain of equal length, the electric capacity of glass suspension insulator string, therefore the electric field problem of non-uniform of composite insulator is very distinct issues, interior umbrella skirt construction has increased the metal part of composite insulator, has improved the uneven problem of electric field pole of conventional composite insulator;
2, full skirt is aging is the insulation fault that occurs in the composite insulator running, often with phenomenons such as full skirt variable color hardening, crackings, cause core rod of insulator to make moist, the line accident rate is increased, the external insulation ability of insulator has been strengthened in the existence of interior full skirt, forms the backup protection after the aging or damage of a kind of external shed;
3, traditional external shed has flexibility, and it will have better mechanical strength under the support of interior full skirt;
4, the shape of the full skirt of conventional composite insulator and layout all adopt the planform on bar-shaped porcelain insulator surface basically, full skirt is less than normal, spacing between the full skirt is also less than normal, can cause between full skirt creepage distance by the air short circuit with arcing short circuit between full skirt takes place like this, the mechanical strength of external shed has been strengthened in the existence of interior full skirt, the outer umbrella disk structure of gamp footpath and long spacing can be provided, reduce the edge effect of full skirt, reduce the unidentified flashover of composite insulator;
5, traditional composite insulator only depends on plug to bear mechanical load, and interior umbrella skirt construction has increased the part of the force of plug, has increased the mechanical strength of plug;
