Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric reactors, in particular to an electric reactor for suppressing circuit closing inrush current. BACKGROUND

[0002] The electric reactor is also called inductor. When a conductor is electrified, a magnetic field will be generated in a certain space range occupied by the conductor. Therefore, all current-carrying conductors have inductance in general sense. However, the inductance of a long straight conductor is small, and the generated magnetic field is not strong. Therefore, the actual electric reactor is a wire wound into a solenoid form, which is called a hollow electric reactor. Sometimes, in order to make the solenoid have greater inductance, an iron core is inserted into the solenoid, which is called a core electric reactor. Electric reactance is divided into inductive reactance and capacitive reactance. The more scientific classification is inductor (inductor) and capacitor (capacitor) collectively referred to as electric reactor. However, because the inductor was developed first in the past, and was called electric reactor, the capacitor is now called capacitor, and the electric reactor specifically refers to the inductor.

[0003] In the power grid circuit system, a series reactor is often needed to suppress the instantaneous inrush current when closing. The electric reactor connected in series in the circuit can suppress and absorb harmonic current, has a filtering effect, and greatly improves the reliability of the power grid operation. However, when the electric reactor is installed and used outdoors, birds often build nests on the smooth top of the electric reactor, which needs to be cleaned frequently. In addition, the high temperature of the top shell of the electric reactor during operation will accelerate the aging of the polyester film. When rainwater seeps into the cracked epoxy of the lead-in line or the horizontal surface, the aging will be accelerated, and the mechanical strength will be lost, causing turn-to-turn short circuit and fire burning. Therefore, in order to solve such problems, the present application provides an electric reactor for suppressing circuit closing inrush current. SUMMARY

[0038] The model of the reactor main body in the present application is: Lu Cup XKSG1-0.8 three-phase limited inrush current reactor.

[0039] In use, when the reactor body 2 is running, the heat and vibration generated by the reactor body 2 during operation heat the water-absorbing and expanding rubber plate 11, and the water-absorbing and expanding rubber plate 11 expands upward under the restriction of the lower reactor body 2, thereby driving the connecting plate 14 to move upward, the connecting plate 14 drives the fixed plate 15 to move upward, and the fixed plate 15 drives the extrusion plate 19 to move upward; through the cooperation of the extrusion plate 19 and the outer wall of the air bag 12, the extrusion plate 19 is driven to move upward to tilt and extrude the outer wall of the air bag 12, and the bottom end of the air bag 12 is extruded to contact the top of the reactor body 2; at the same time, the liquid pump in the conveying pipe is started to convey the collected rainwater in the collecting box 5 into the air bag 12; the rainwater in the air bag 12 is used to quickly cool the outer shell of the reactor body 2, so as to avoid the temperature of the top shell of the reactor body 2 being too high to accelerate the aging of the polyester film and affect its normal use; and the vibration generated by the reactor body 2 during operation shakes the rainwater in the air bag 12, so that the rainwater filled in the air bag 12 uniformly cools and radiates heat to the top shell of the reactor body 2, avoiding the accumulation of rainwater in the air bag 12, which makes it difficult for the heated rainwater at the bottom of the air bag 12 to mix with other rainwater in the air bag 12 and quickly radiate heat to the top shell of the reactor body 2.
