Abstract

The invention discloses a capacitor voltage transformer with an external error adjusting structure, belonging to the technical field of a voltage transformer. The capacitor voltage transformer comprises a binding post (1), a porcelain bushing (2), an oil tank (3), a secondary terminal box (4) and an adjusting line segment box (5), wherein the porcelain bushing (2) is installed above the oil tank (3); the secondary terminal box (4) and the adjusting line segment box (5) are symmetrically arranged at the two sides of the oil tank (3); and the binding post (1) is positioned above the porcelain bushing (2). The capacitor voltage transformer has the characteristics of being easy in operation during product assembly, simple and sanitary in error adjustment during product test, and convenient in error adjustment on site, omitting the process of assembling and disassembling the product, and the like.

Description

technical field [0001] The invention belongs to the technical field of voltage transformers, in particular to a capacitive voltage transformer with an error external adjustment structure. Background technique [0002] The capacitive voltage transformer is composed of two parts: a capacitive voltage divider and an electromagnetic unit. Since the capacitance of the capacitive voltage divider has a great influence on the product error, it is necessary to debug the error by adjusting the line segment during the finished product test; and because the capacitance of the capacitive voltage divider With the change of external temperature, it will also change accordingly, which will affect the error of the product. Sometimes it is necessary to re-adjust the error of the qualified product on site. [0003] In the past, when adjusting the product error of the capacitive voltage transformer, the capacitive voltage divider needs to be removed, and then the cover of the electromagnetic un...
