Abstract
The utility model relates to a supporting post insulator seismic-resistant circular-current-preventive structure, which is provided with annular plates arranged between every two sections of supporting post insulators in series connection. Each annular plate comprises two semi-annular plates integrally connected via an insulating connecting device. Each connecting device includes a connecting plate and an epoxy glass fabric plate, and the epoxy glass fabric plates placed among the connecting plates and the semi-annular plates are connected with the connecting plates and the semi-annular plates via fasteners. The fasteners are bolts, insulating gaskets and insulating sleeves are arranged among the fasteners and the semi-annular plates, and one end of each insulating sleeve is abutted to the bottom surface of one bolt head while the other end is fixed via a sealing pad. The structure connects the twelve supporting post insulators into a whole, strengthens seismic resistance of the supporting post insulators, avoids circular current by separating each two annular plates by an insulating structure, and reduces excessive heat.
Description
Technical field
The utility model relates to reactor manufacturing technology field, and specifically a kind of post insulator antidetonation is prevented circulation structure.
Background technology
Usually ± post insulator of the dry smoothing reactor bottom of 400kV and above electric pressure is made up of 12 posts, and to be arranged in diameter equably be to be about on the circumference of 3.6m, every column insulator is about 7～12m height (post insulator that is Φ 280 by about 2.5 meters high diameters of more piece is composed in series, and determines the joint number and the height of post insulator according to different electric pressures).Because the post insulator material is a fiberglass, form by multi-section serial, and also not only high but also thin, do not satisfy shockproof requirements.
In order to strengthen steadiness, improve shock resistance, between post insulator, fix by adding the metal ring plate.But because dry smoothing reactor electric pressure height, electric current is big, causes coil bottom electric field strength height easily, and the metal ring plate produces circulation, and it is overheated to cause.
The utility model content
Exist the metal ring plate to produce circulation after adding the metal ring plate between the post insulator at dry smoothing reactor in the prior art, cause weak points such as overheated, the technical problems to be solved in the utility model provides a kind of anti-circulation structure of antidetonation of post insulator.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is:
The utility model post insulator antidetonation is prevented circulation structure, is the annular slab between every joint of being located at the post insulator that is connected in series, and this annular slab is made up of two semi-circular plates, connects as one by the jockey with insulation property.
Described jockey comprises connecting plate and epoxy resin bonded fiber, and epoxy resin bonded fiber is positioned between connecting plate and the semi-circular plate, connects by securing member; Described securing member is a bolt, is provided with insulating washer and insulating case between itself and the semi-circular plate; One end and the bolt head bottom surface of insulating case connect, and the other end is fixed by sealing gasket.
The utlity model has following beneficial effect and advantage:
1. 12 column insulators are connected as one, strengthened the shock resistance of post insulator;
2. separate with insulation system in the middle of two annular slabs, avoided the generation of circulation, it is overheated to have reduced.
