Screwing type hard pressing plate for transformer substation

Abstract

The invention discloses a screwing type hard pressing plate for a transformer substation which comprises a fixing bottom plate, wherein fixing pipes are arranged on the two sides of the fixing bottom plate. oppositely arranged conductive core columns respectively connected with the corresponding fixing pipes; positioning pieces oppositely arranged, wherein the outer sides of the corresponding conductive core columns are sleeved with the positioning pieces respectively; a rotating part one end of which is rotationally connected with the fixed bottom plate, and the other end of which is in a free state; a Z-shaped connecting piece connected with the rotating part, wherein limiting clamping grooves are formed in the two ends of the Z-shaped connecting piece respectively, and the limiting clamping grooves are used for being clamped with conductive core columns; a pressing piece connected with the rotating part. When the rotating part rotates, the rotating part drives the two ends of the Z-shaped connecting piece to make contact with the corresponding conductive core columns respectively, and the rotating part further drives the pressing piece to drive the positioning pieces to fix the two ends of the Z-shaped connecting piece to the corresponding conductive core columns respectively. According to the invention, the input and withdrawal difficulty of the hard pressing plate is greatly reduced, the hard pressing plate is convenient to use by a worker, and the stability of the hard pressing plate during use is ensured.

Description

technical field [0001] The invention belongs to the technical field of equipment for substations, and in particular relates to a twisted hard pressing plate for substations. Background technique [0002] The substation refers to the place where the voltage and current are transformed, received and distributed in the power system. The substation in the power plant is a step-up substation. Its function is to boost the power generated by the generator and feed it to the high-voltage power grid. In the use of substations, it is necessary to use hard pressure plates. The hard pressure plate is also called the protection pressure plate. It is a continuous piece installed on the protective screen. Its closing and opening represent throwing and retreating. The hard pressure plate is generally divided into a function pressure plate and an outlet pressure plate. The function pressure plate is a selection control of the protection function. Its switch-on and withdrawal affect the real...

AI Technical Summary

Problems solved by technology

[0003] At present, the hard pressing plate actually used in the field is composed of a conductive stem, a connecting piece and a protective cover. The hard pressing plate of the connecting piece is manually operated to realize the input (connecting the connecting piece and the conductive stem) and withdrawal (connecting the connecting piece and the conductive stem) of the hard pressing plate. The core column is disconnected), but whether the hard pressing plate is really put in, you can only try the connecting piece by hand, which is inconvenient, and the hard pressing plate is prone to loosening after being put in, which will affect the performance of the hard pressing plate
