The high-voltage supporting insulator has good mechanical performance, can reliably support high-voltage primary equipment, has high anti-fracture performance and the advantages of being rapid and convenient to install and the like, can well prevent the supporting insulator from breaking and prevent occurrence of a converting station primary equipment safe accident, saves a large number of maintenance expenses, and guarantees normal running of the converting station primary equipment. The high-voltage supporting insulator is suitable for electric system high-voltage electric transmission and transformation equipment.
Description
Technical field
The utility model relates to a kind of high-voltage strut insulator, belongs to high voltage power transmission and transforming equipment technology field.
Background technology
In transformer station's high voltage primary equipment was installed, post insulator played important connection and supporting role, is the more High-Voltage Electrical Appliances primary equipment of transformer station's scope of application in the electric power system as high voltage isolator.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.Make isolator operating mechanism corrosion bite at long-term frost sleet in service and airborne filth and corrosive gas, not in place and other faults of closing a floodgate often appear in isolating switch easily, its post insulator bottom, two ends is stressed bigger during disconnecting switch operation, is prone to phenomenon of rupture.Cause transformer station to stop transport, have a strong impact on Supply Security and reliability, even cause the large-area power-cuts event 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 vitals safe and reliable in the secure transformer station only just can reach the purpose of safe power transmission and distribution, can prevent that the large-area power-cuts event from taking place.
Summary of the invention
The purpose of this utility model is to cause the transmission line fluctuation of service, the large area blackout of initiation, the safety in production of guarantee high voltage transmission and distribution network in order to prevent the fracture of power transmission and transforming equipment post insulator effectively; In order to reduce the post insulator fracture probability, promoted the high-tension power transmission and transformation equipment serviceability rate, the utility model discloses a kind of high-voltage strut insulator.
The technical solution of the utility model is, the utility model high-voltage strut insulator 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 inner surface central authorities of lower surface metal flange are provided with reinforced pier; The upper surface metal flange is bonded and fixed at high-strength porcelain upper part of body; Lower surface metal flange reinforced pier is bonded and fixed at the bottom of high-strength porcelain body, and reinforced pier has been strengthened the shearing strength of lower surface metal flange neck greatly, has significantly reduced the fracture situation of post insulator neck.
The cross section of metal flange inner surface reinforced pier can be different shape, as circle, oval polygon etc.; The height of reinforced pier depends on the needs, and the insulator body lower surface that high-strength porcelain is fired is reserved with and is fit to the gap that reinforced pier inserts, and should evenly be full of cement gel in the gap.Improve its neck stress by above technical measures and realize the anti-fracture function of high voltage primary equipment post insulator.Installation method is simple, rapid.
The beneficial effects of the utility model are: by the lower surface metal flange that has reinforced pier of particular design, not only increased the mechanical strength of high voltage primary equipment post insulator, reduce the post insulator fracture probability, promoted the high-tension power transmission and transformation equipment serviceability rate.Thereby effectively prevent the pernicious power outage of large tracts of land because of high voltage primary equipment post insulator fracture initiation, improve electrical network power transmission and distribution safety in production level and ensure electrical network power transmission and distribution safety.
The utility model high-voltage strut insulator has good mechanical performance, can support the high voltage primary equipment reliably, has higher anti-fracture performance, characteristics such as convenience quick for installation, can prevent the post insulator fracture well, prevention transforming plant primary equipment security incident takes place, and saves a large amount of maintenance costs, has ensured the normal operation of transforming plant primary equipment.
The utility model is applicable to electric power system high voltage power transmission and transforming equipment.

Embodiment
The embodiment of a kind of high-voltage strut insulator of the utility model as shown in drawings.
The utility model high-voltage strut insulator is made up of upper surface metal flange 1, high-strength porcelain body 2 and lower surface metal flange 3, and the inner surface of upper surface metal flange 1 is welded with many reinforcements; To have cross section be that hexagon is strengthened pier 31 in the centre on the inner surface of lower surface metal flange 3; Upper surface metal flange 1 is bonded and fixed at the top of high-strength porcelain body 2; Lower surface metal flange hexagon is strengthened the bottom that pier 31 is bonded and fixed at high-strength porcelain body 2, to be hexagonal reinforced pier 31 then strengthened the shearing strength of lower surface metal flange neck as reinforcement to cross section greatly, significantly reduced the fracture situation of post insulator neck.
It is hexagonal reinforced pier that present embodiment lower surface metal flange inner surface reinforced pier is chosen as cross section, and the cross section of lower surface metal flange inner surface reinforced pier can be circle, ellipse or polygon etc., and the hexagonal effect of cross section is better.
