Series filter reactor protection device

Abstract

The invention provides a series filter reactor protection device, which comprises an outer shell. A first fixing plate is mounted at the bottom end of the interior of the outer shell; a three-phase series filter reactor is mounted at the top of the first fixing plate; a second fixing plate is mounted at the top of the three-phase series filter reactor; three wiring posts are mounted at the top ofthe three-phase series filter reactor; the top ends of the wiring posts penetrate through the second fixing plate and the outer shell and extend to the top of the outer shell; shells are mounted on the two side edges of the interior of the outer shell; commutators are fixedly installed in the shell and located on one side edge of the outer shell; wires are fixedly mounted at the top and the bottomof the commutators correspondingly; the ends, away from the commutators, of the wires are connected with a first refrigeration sheet and a second refrigeration sheet correspondingly; the joint of thefirst refrigeration sheet and the second refrigeration sheet is sleeved with a refrigeration bin; and a flow guide plate is fixedly mounted at the end, away from the commutator, of the refrigerationbin.

Description

technical field [0001] The invention relates to a protection device for a series filter reactor, which belongs to the technical field of reactors. Background technique [0002] A reactor is also called an inductor. When a conductor is energized, it will generate a magnetic field in a certain space it occupies, so all electrical conductors that can carry current have a general sense of inductance; however, the inductance of a long and straight conductor that is energized is small. The generated magnetic field is not strong, so the actual reactor is a wire wound into a solenoid, which is called an air-core reactor; sometimes in order to make the solenoid have a larger inductance, an iron core is inserted into the solenoid, which is called a reactor. Core reactor. Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductive reactance and capacitive reactance are collectively referred to as reactors. However, since...

Reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is that inductive reactance and capacitive reactance are collectively referred to as reactors. However, since inductors first existed in the past and were called reactors, what people call capacitors now It is a capacitive reactor, and a reactor refers specifically to an inductor; the long-term normal operation time of the reactor under the rated load is the service life of the reactor; the service life of the reactor is determined by the material used to make it; There are two types of metal materials and insulating materials; metal materials are resistant to high temperatures, while insulating materials will gradually lose their original mechanical and insulating properties at higher temperatures for a long time. The higher the temperature, the weaker the mechanical and insulating properties of insulating materials The faster it ages, the faster it ages, which leads to a shorter service life of the reactor, so now a series filter reactor protection device is needed
