Description
Technical field
The present invention relates to lightning-arrest and insulator technology field, is a kind of lightning protection pillar insulator.
Background technology
China utility model mandate publication number CN2713598Y, discloses name and is called: the utility model patent of lightning rod type insulator.Its structure is, top gold utensil and bottom gold utensil, stove bolt is arranged on the gold utensil of top through acupuncture gland, top gold utensil, housing and bottom gold utensil form a closed chamber, between chamber internal upper part gold utensil and resistor valve sheet, spring is housed, internal clearance is had between resistor valve sheet and bottom gold utensil, tapered electrode, resistance ring are installed in internal clearance, and internal clearance and resistor valve sheet and bottom gold utensil connecting portion are provided with pad, bottom gold utensil is fixed by pin, the inwall of housing has rubber full skirt and insulating cylinder, and king-bolt is enclosed within the gold utensil of bottom.Shortcoming of the present utility model is, the glass steel shell that housing adopts epoxy resin and glass cloth to be composited usually, because lightning voltage is by discharge process during housing, electric arc will be produced to shell inner surface to burn, due in existing housing without preventing arc measure, cause housing to be burnt to be out of shape, even damage.Owing to adopting bell towards the tapered electrode of radial direction, the hard arc of lightning voltage abrupt release easily hits damage electrode, even housing.More seriously, the high pressure flue gas that the hard arc burning of lightning voltage moment produces discharges nowhere, can only suppress in housing, when high pressure flue gas exceedes the bearing capacity of housing, will destroy housing; Even if the pressure of high pressure flue gas is lower than the bearing capacity of housing, in the process of high pressure flue gas step-down diffusion gradually in housing, flue dust falls to hanging on the surface of the built-in resistor disc of housing, resistance ring and sparking electrode, affects its function, reduces useful life.
Summary of the invention
The object of the invention is, overcome the deficiencies in the prior art, substantial improvements and innovation are carried out to prior art, there is provided a kind of and integrate metal oxide arrester and composite insulator purposes, rational in infrastructure, intensity is high, reliability is high, lightning-arrest effective, long service life, guarantees safe lightning protection pillar insulator.
The object of the invention is to be realized by following technical scheme: a kind of lightning protection pillar insulator, it comprises: top gold utensil, bottom gold utensil, housing, top gold utensil, housing and bottom gold utensil are connected the closed chamber of composition one successively, resistor disc and resistance ring is equipped with successively from top to bottom in chamber, sparking electrode is built-in with at resistance ring, spring is equipped with between the top gold utensil in chamber and resistor disc, the outer wall of housing is fixed with rubber full skirt, it is characterized in that, described housing is made up of inner insulating layer, middle carbon fabric reinforcement and external insulation layer compound; Be built-in with the refractory ceramics pipe with housing inner insulating layer matched in clearance at described chamber, described resistor disc and resistance ring are placed in refractory ceramics pipe, and described sparking electrode is axially placed in resistance ring in pairs; The one-way exhaust valve communicated with air is built-in with at bottom gold utensil.
The discharge end of described sparking electrode is arc.
Lightning protection pillar insulator of the present invention and prior art have and identical integrate outside metal oxide arrester and composite insulator purposes feature, more important advantage is, owing to adopting the housing be made up of inner insulating layer, middle carbon fabric reinforcement and external insulation layer compound, enhance the rigidity of the tension of housing, Compressive Strength and resistance to deformation, the high pressure smoke-shock that the hard arc burning can bearing lightning voltage moment produces, guarantees use safety, owing to being built-in with the refractory ceramics pipe with housing inner insulating layer matched in clearance at chamber, at refractory ceramics pipe built-in resistor sheet and resistance ring, sparking electrode is axially placed in resistance ring in pairs, and the discharge end of sparking electrode is arc, sparking electrode is axially opposed in atmospherical discharges gap in pairs, the hard arc energy that lightning voltage can be made to produce instantaneously discharges vertically, again because the discharge end of sparking electrode is arc, hard arc arcuately holds decay release level and smooth, hard arc is thoroughly decayed in the discharging gap of two sparking electrodes, avoid the tapered electrode of existing employing bell towards radial direction, the hard arc easy breakdown potential balk ring phenomenon of lightning voltage abrupt release occurs, refractory ceramics pipe has high temperature resistant, anti-yaw damper ability, can stop and avoid housing failure.It is rational in infrastructure, and intensity is high, and reliability is high, and lightning-arrest effective, long service life, guarantees safety.
