Voltage transformer with quick-release end cover

Abstract

The invention relates to the technical field of transformer equipment, in particular to a voltage transformer with a quick-release end cover. The voltage transformer comprises a transformer cover body and an end cover, wherein the end cover is correspondingly clamped at the upper end of the transformer cover body, fixing clamping grooves extending inwards are symmetrically formed in two corresponding side edges of the end cover, the side edges, corresponding to the fixing clamping grooves, of the v cover body is provided with clamping and fixing components which are clamped into the fixing clamping grooves in a matched mode so that the end cover can be fixedly clamped at the upper end of the transformer cover body. In a lateral horizontal pressing mode, a clamping plate is pressed by a force application rod, limiting clamping rods relatively slide in the limiting clamping grooves under the cooperation of the acting force of reset tension springs, clamping and unclamping movement is conducted in the sliding process, and the mounting and dismounting process of the end cover and the mutual inductor cover body is achieved; and the voltage transformer is long in service life, and compared with an existing connecting mode, the maintenance efficiency of maintenance personnel is greatly improved, and the maintenance time of the maintenance personnel is greatly shortened.

Description

technical field [0001] The invention relates to the technical field of transformer equipment, in particular to a voltage transformer with a quick-detachable end cover. Background technique [0002] Potential transformer is one of the more common electrical appliances in people's life, and it is an instrument used to transform voltage. The purpose of the voltage transformer to transform the voltage is mainly to supply power to the measuring instrument and the relay protection device, to measure the voltage, power and electric energy of the line, or to protect the valuable equipment and motor in the line when the line fails. and transformers. During the use of the existing voltage transformer, because the circuit may encounter different situations, such as overload, etc., the voltage transformer is very likely to be damaged. Since the voltage transformer shield and the end cover at the upper end of the shield are generally connected by bolts or screws, and the voltage transf...

AI Technical Summary

Problems solved by technology

Since the voltage transformer shield and the end cover at the upper end of the shield are generally connected by bolts or screws, and the voltage transformer is generally used outdoors, this leads to the corrosion and rust of the bolts or screws, making the voltage transformer It is difficult to open the end cover, which seriously affects the maintenance efficiency and maintenance time
