Electronic current and voltage combined transformer

Abstract

The invention discloses an electronic current and voltage combined transformer. The transformer comprises a shell, a voltage transformer element, a current transformer element and a supporting base. The voltage transformer element is installed at the top end of the interior of the shell, the current transformer element is installed at the bottom end of the interior of the shell, the supporting base is fixedly connected to the bottom end of the shell, and a heat dissipation mechanism is installed at the bottom end of the shell. According to the electronic current and voltage combined transformer, through cooperatively using fan blades, a motor, a protective cover, a vertical rod and the like, the use of electrical components is prevented from being influenced by over-high temperature. Through cooperatively using the air outlet pipe, the net plate, the V-shaped plate, the screw and the like, the problem that dust affects the use of electrical apparatus elements is solved. Through the cooperative use of a protective shell, a rubber ring, a pressing plate, a spring and the like, it is avoided that wires are disordered to affect the maintenance of the whole mechanism, and through the cooperative use of a rotating rod, a door plate, a tempered glass plate and the like, the operating conditions of the electrical apparatus elements in a shell are observed through the tempered glass plate.

Description

technical field

[0001] The invention relates to the technical field of current and voltage transformers, in particular to an electronic combined current and voltage transformer. Background technique

[0002] The electronic transformer is one of the key equipment to meet the development of high-voltage electrical equipment in the modern power system to the direction of intelligence, modularization, miniaturization, multi-function, and maintenance-free. The electronic transformer is also the basic sensor of the smart grid, and the combination of voltage and current Transformers can be used in substations, high-voltage lines, switching stations, switchgears, ring network cabinets, etc., but the existing electronic current and voltage combination transformers, the heat generated by the electrical components in the housing If the temperature in the casing is too high, it will affect the work of the electrical components, resulting in a decline in the practicability of the overall...
