Single-phase high-voltage pouring type reactor

Technical Field

The utility model relates to the technical field of reactors, in particular to a single-phase high-voltage casting type reactor.

Background

Reactors, also called inductors, are electrical conductors that, when energized, generate a magnetic field in a certain spatial area occupied by a conductor, so that all electrical conductors capable of carrying current are inductive in the general sense. However, the inductance of the electrified long straight conductor is small, and the generated magnetic field is not strong, so that the actual reactor is in a mode that a conducting wire is wound into a solenoid, and is called as an air-core reactor; in order to make this solenoid have a larger inductance, a core, called a core reactor, is sometimes inserted into the solenoid. Reactance is divided into inductive reactance and capacitive reactance, and the more scientific classification is that inductive reactance (inductor) and capacitive reactance (capacitor) are collectively called reactor, however, since the inductor is existed in the past and is called reactor, the capacitor is called reactor, and the reactor is specially called inductor.

The existing reactor is often rusted due to the fact that an iron core is wetted and water enters the iron core, and therefore fire accidents are caused due to overhigh temperature.

For this reason, we propose a single-phase high-voltage cast reactor.
