Abstract
The invention discloses a pressure drum of a capacitive divider, which is applied in the capacitive divider and is arranged between a core of the capacitive divider and a bottom plate, and comprises an insulation drum body, a middle-voltage wire-incoming hole and a low-voltage wire-incoming hole are formed in the drum wall of the insulation drum body, fixing parts are arranged under the drum wall, and the pressure drum is fixed on the bottom plate through the fixing parts. Compared with the structure of the traditional insulation body, the pressure drum of the capacitive divider has the advantages that the structure is simple, the implementation is easy, the insulation property is good, the pressure resistance strength is high, and no deformation is caused.
Description
Technical field
The present invention relates to a kind of capacitor voltage divider, especially relate to a kind of capacitor voltage divider and receive pressure cylinder.
Background technology
As everyone knows, in order to guarantee capacitor voltage divider safety, normal work, in the porcelain bushing of packing the capacitor voltage divider fuse into; To between the metal base plate of voltage divider fuse and porcelain bushing, place an insulating bodies, to guarantee the insulation of fuse and metal base plate, at present; The method of generally using is to be cut into identical shape to tens carpenter's insulating boards; Stack then, tie up bulk, in the capacitor voltage divider sleeve pipe of packing into after handling through tens hours oven dry again with cloth; But the intensity of this insulating bodies that is made up of tens carpenter's insulating boards is not high; Easy deformation, and possibly have moisture in carpenter's insulating paper, and then cause the insulating properties of insulator also not high.
Summary of the invention
To above-mentioned technical problem, the object of the present invention is to provide a kind of capacitor voltage divider to receive pressure cylinder, it has simple in structure, is easy to realize; Intensity is high, can not be out of shape and the characteristics of good insulation preformance.
The objective of the invention is to realize through following technical scheme:
A kind of capacitor voltage divider receives pressure cylinder; Be arranged between capacitor voltage divider fuse and the base plate; It comprises insulating cylinder body, in offering on the barrel of said insulating cylinder body, the low pressure entrance hole, said in voltage lead wires with during low-voltage lead passes through respectively, the low pressure entrance hole is connected with the interior mesolow terminal of insulating cylinder body; And the barrel of said insulating cylinder body below is provided with fixture, and said fixture is fixed on insulating cylinder body on the base plate.
Especially, said insulating cylinder body is formed by the cast of epoxy resin one.
Especially, said in, the low pressure entrance hole is two the relative holes one on the other that are opened on the insulating cylinder body, the low pressure entrance hole is arranged in the below of pressing entrance hole.
Especially, said mesolow terminal is an integral structure.
Beneficial effect of the present invention does, it is to form insulating cylinder body by the cast of epoxy resin one that said capacitor voltage divider receives pressure cylinder, and on insulating cylinder body, offering, the low pressure entrance hole; Insulator than tens carpenter's insulating boards formations of Traditional use; It is good insulation preformance not only, and compressive resistance is high, can not be out of shape; And simple in structure, be easy to realize.
