Abstract
The invention discloses a low-partial discharge simple high-voltage leading-out bushing, which comprises a bushing body, a flange and a conducting rod, wherein the flange is connected with the bushing body; the conducting rod is used for externally leading out high voltage from the interior of the bushing body; the bushing body is manufactured by performing one-step casting on high temperature-resistant high-insulating plastic particles; the inner surface of the bushing body is very smooth, thus, partial discharge can be avoided happening; the outer surface of the bushing body is designed to be of a skirt structure, thus, the creep age distance of the surface can be effectively increased; the upper part and the lower part of the bushing body are respectively provided with an equalizing ring; the flange is a case cover flange and is arranged at the lower part of the bushing body; the bottom part of the conducting rod is provided with a conducting rod equalizing ball; an upper equalizing ring is arranged between an upper equalizing ring upper sleeve and an upper equalizing ring lower sleeve, and is located at the upper part of the bushing body; the top part of the conducting rod is provided with a high-voltage lead bolt; and an equalizing ring is arranged in the bushing body. In the scheme disclosed by the invention, the low-partial discharge simple high-voltage leading-out bushing is manufactured by performing the one-step casting on the high temperature-resistant high-insulating plastic particles, thus, the low-partial discharge simple high-voltage leading-out bushing is not easy to deform, has high strength and low manufacturing cost and can be produced in batch.
Description
Technical field
The present invention relates to a kind of high pressure extraction tube, simple and easy high pressure extraction tube is put in particularly a kind of low office, belongs to electrical technology field.
Background technology
In high-tension testing apparatus, resemble testing transformer, excitation transformer is put in no office, all needs the high pressure extraction tube; The high pressure extraction tube all adopted porcelain vase sleeve pipe or condenser-type terminal in the past; Though porcelain vase sleeve pipe cost is low, easy to be broken once colliding, the sleeve pipe leakage of oil that makes. and condenser-type terminal often cost is very high, and technology relative complex.
Summary of the invention
Technical problem to above-mentioned existence the objective of the invention is: proposed a kind of not yieldingly, the intensity height can be produced in batches, and simple and easy high pressure extraction tube is put in the low office of inexpensive.
Technical solution of the present invention is achieved in that a kind of low office puts simple and easy high pressure extraction tube, comprises union body, the flange that is connected with union body, by the conducting rod of outwards drawing high pressure in the union body; Described union body is once cast by high temperature resistant high ambroin particle and processed, and is very smooth at the union body inner surface, the generation of can the office of avoiding putting; The outer surface of said union body is arranged to the shirt rim structure, can effectively increase the creepage distance on surface.
Preferably, the top and the bottom of said union body are provided with grading ring.
Preferably, said flange is the case lid flange, is arranged on the bottom of union body.
Preferably, the bottom of said conducting rod is provided with a conducting rod voltage equalizing ball.
Preferably, last grading ring is arranged on the grading ring between cover and last grading ring trap, and is positioned at the top of union body.
Preferably, the top of conducting rod is provided with the high-voltage connection bolt.
Preferably, be provided with grading ring in the union body.
Because the utilization of technique scheme, the present invention compared with prior art has advantage:
Simple and easy high pressure extraction tube is put in the present invention program's low office, processes by can high temperature resistant high ambroin particle once casting, and not yielding, the intensity height can be produced in batches, inexpensive.
Description of drawings
Below in conjunction with accompanying drawing technical scheme of the present invention is described further:
