Abstract
The adjustable reactance energy-saving coil comprises master coils and a control coils on a same iron core. The control coil uses DC control current. Two C-shaped iron cores in mirror symmetry are wound into two master coils. The two master coils are connected in series or in parallel. one end of each iron core approaches to each other. A control coil winds around the other ends of the two iron core simultaneously. DC current of the control coil control magnetic saturation status of the master coil namely inductance. Magnetic flux of the two iron core sets off each other. Effect of the master coil on the control coil is reduced to the minimum level. Voltage changes on the master coil dose not generate high tension on the control coil. The adjustable reactance energy-saving coil can maintain a constant equipment voltage to save energy when it is connected in an electric line such as city light system. The product is characterized in simple structure, low cost, significant energy saving. Therefore, it is widely applicable.
Description
(1) technical field
The utility model relates to the electric elements field, is specially a kind of regulative reactance Energy-saving coil.
(2) technical background
The regulative reactance Energy-saving coil is mainly used in voltage drop in the control circuit in reasonable level, thereby reaches energy-conservation purpose.The regulative reactance Energy-saving coil main winding of connecting in the line has the galvanic control coil of feeding on same iron core.Force down or just often, regulative reactance Energy-saving coil main coil is in saturation condition when line electricity, its inductance value is minimum, and voltage drop thereon is also minimum, on the main power consumption equipment of the voltage on the circuit.And when the voltage rising, when line current increased, regulative reactance Energy-saving coil main coil was rapidly near undersaturated condition, inductance value strengthens, and voltage drop increases on it, and the voltage of equipment remains unchanged on the circuit and make, because of the caloric value of Energy-saving coil little, thereby reach energy-saving effect.
The main coil inductance value of regulative reactance Energy-saving coil is directly proportional with the iron core permeability, and permeability is directly proportional with the electric current of control coil.Therefore the electric current of control coil is by very little direct current, and promptly may command regulative reactance Energy-saving coil main coil is in magnetic saturation or undersaturated condition, and after main coil reached saturation point, it is infinitely small that its inductance value is tending towards.Controlled the inductance value of main coil, also just can be controlled at the pressure drop size on the Energy-saving coil main coil, to adapt to the variation of voltage on the circuit.
But because main coil and control coil be on same iron core, the voltage drop meeting on the main coil reflects on control coil.The turn ratio of the two coil is big more, and voltage ratio is also just big more.Voltage on the control coil even can reach more than 10,000 volts.So control circuit just must adopt high withstand voltage equipment, cost improves greatly, and security performance also descends many.Make the application of regulative reactance Energy-saving coil be restricted.
(3) utility model content
The purpose of this utility model is a kind of regulative reactance Energy-saving coil of design, and its control coil can be controlled the magnetic saturation degree of main coil, but main coil offset in a large number to the influence of control coil voltage, and control coil can not produce high voltage.
The regulative reactance Energy-saving coil of the utility model design is included in main coil and the control coil on the same iron core, control coil inserts the DC control electric current, two are mirror two main coils of difference coiling on the C of symmetry sections core, two main coils are in series or in parallel with each other, the other end of two iron cores is drawn close, and a control coil is wound on the other end of two iron cores simultaneously.Because of the magnetic flux in two iron cores of symmetry is cancelled out each other, main coil drops to minimum to the influence of control coil, and the change in voltage on the main coil can not produce high voltage on control coil.Thereby this regulative reactance Energy-saving coil can use low withstand voltage, low power element, reduced product cost, also improved security performance.This regulative reactance Energy-saving coil is applicable in the electric appliance circuits that change in voltage rises and falls, and keeps the power on voltage of device equipment of circuit constant, reaches purpose of energy saving.As can be used for the urban lighting system, the magnetic saturation state of the size of current control main coil of the control coil of this regulative reactance Energy-saving coil also just can be controlled at the pressure drop size on the main coil that is connected in the circuit, to adapt to the variation of voltage on the lamp wiring.Voltage on the lamp is remained unchanged, steady operation, thus reach energy-saving effect.And this regulative reactance Energy-saving coil is pressure regulation amplitude modulation in electrical network, and electrical network is had significant protective effect.This regulative reactance Energy-saving coil is simple in structure, and is with low cost, and obvious energy saving effect is arranged.Be suitable for applying.
