Abstract
A fracture-resistant support insulator comprises a high strength porcelain body, an upper end surface metal flange and a lower end surface metal flange, wherein a plurality of reinforcing ribs (11) are welded on the inner surface of the upper end surface metal flange (1), the upper end surface metal flange (1) with the reinforcing ribs is cemented with the high strength porcelain body by cement; the upper end surface metal flange (1) is adhered on he upper part of the high strength porcelain body, and the lower end surface metal flange is adhered on the lower part of the high strength porcelain body. After the plurality of reinforcing ribs are welded on the inner end surface of the upper end surface metal flange of the support insulator, the fracture probability of the support insulator is greatly reduced, and the rate of equipment in good condition is increased; the unstable operation of a transmission circuit due to fracture of the support insulator of electric transmission and transformation equipment is effectively prevented, and furthermore large-area power failure accident is avoided, and the safety production operation of a high voltage transmission and distribution network is ensured. The fracture-resistant support insulator is suitable for high voltage substation primary equipment.
Description
Technical field
The utility model relates to a kind of anti-fracture post insulator, belongs to high voltage power transmission and transformation equipment technology field.
Background technology
In transformer station's high voltage primary equipment was installed, post insulator played important connection and supporting role, as the High-Voltage Electrical Appliances primary equipment that high voltage isolator is use amount maximum in the electric power system, range of application is the widest.Safety when guaranteeing the high-tension apparatus turnaround of unit, between the equipment and other live parts of need maintenance, form a tangible interruption intervals with isolating switch, so not folding of isolating switch load current and fault current, be in "on" position for a long time and less the operation, and its structure is simple relatively, be easy to make, so isolating switch is again least valued electric equipment.Often occur some faults easily at long-term isolating switch in service, rainwater and airborne filth make operating mechanism corrosion bite, and its two ends post insulator neck is stressed bigger during disconnecting switch operation, phenomenon of rupture very easily occurs.Cause circuit, platform district to stop transport, influence power supply reliability, even cause the pernicious power-off event of large tracts of land to take place.
The high voltage installation post insulator is requisite vitals in the electrical network, be the important leverage that substation safety is produced at the anti-fracture post insulator in the important repair and maintenance equipment technology of ultra-high-tension power transmission line field, its safe operation is directly connected to the safety and stability of electrical network and to the reliability of user's power supply.This device is to utilize the post insulator of special construction to realize the anti-fracture function of post insulator.Facts have proved that the only safe and reliable support and connection of vitals in the secure transformer station just can reach the purpose of safe power transmission and distribution, can prevent that the pernicious power-off event of large tracts of land from taking place.
Existing post insulator is that insulator body and the upper and lower end face metal flange gummed fired by high-strength porcelain form, and the insulator body gluing of using cementing technology that upper and lower end face metal flange and high-strength porcelain are fired is one.And rupturing appears in the splicing neck place of the existing post insulator fault in use insulator body that to be upper surface metal flange and high-strength porcelain fire.
Summary of the invention
The purpose of this utility model is, in order to solve the neck breakage problem that existing post insulator in use exists, prevent the fracture of power transmission and transforming equipment post insulator effectively and cause the transmission line fluctuation of service, the large area blackout that causes ensures the safety in production of high voltage transmission and distribution network; Disclose a kind of anti-fracture post insulator, to reduce the post insulator fracture probability, promoted the high-tension power transmission and transformation equipment serviceability rate.
The technical solution of the utility model is, the anti-fracture post insulator of the utility model is made up of upper surface metal flange, high-strength porcelain body and lower surface metal flange, and the inner surface of upper surface metal flange is welded with many reinforcements; The upper surface flange that has many reinforcements is bonded to one by cement and high-strength porcelain body; The upper surface metal flange is bonded and fixed at high-strength porcelain upper part of body; The lower surface metal flange is bonded and fixed at the bottom of high-strength porcelain body.
When making the anti-fracture post insulator of the utility model, the upper surface metal flange that has reinforcement is bonded to one by cement and high-strength porcelain body, reinforcement has then been strengthened the shearing strength of upper surface metal flange neck greatly, has significantly reduced the fracture situation of post insulator neck.
The beneficial effects of the utility model are that the utility model has reduced the post insulator fracture probability greatly after the upper surface of post insulator metal flange inner face has welded many reinforcements, promoted the high-tension power transmission and transformation equipment serviceability rate; Prevented the fracture of power transmission and transforming equipment post insulator effectively and caused the transmission line fluctuation of service, the situation of the large area blackout of initiation has ensured the safety in production of high voltage transmission and distribution network.
The utility model is applicable in transformer station's high voltage primary equipment and uses.

Embodiment
The utility model embodiment as shown in Figure 4.The anti-fracture post insulator of present embodiment is made up of upper surface metal flange 1, high-strength porcelain body 2 and lower surface metal flange 3; On the inner surface of upper surface metal flange, vertically with inner surface be welded with three screw-thread steel reinforcements 11, reinforcement 11 is to be 120 ° of distributions at same circumference in the position of the inner surface of upper surface metal flange 1.
The upper surface metal flange, lower surface metal flange and the high-strength porcelain body 2 usefulness cement gels that are welded with reinforcement are struck up partnership, and upper surface metal flange 1 is bonded and fixed at the top of high-strength porcelain body 2; Lower surface metal flange 3 is bonded and fixed at the bottom of high-strength porcelain body 2; Be welded on reinforcement 11 on the upper surface metal flange 1 with together cement-bonded, strengthened the adhesion strength of upper surface metal flange 1 with high-strength porcelain body 2 greatly.
