A reactance filter energy saver

Abstract

The invention discloses a reactance filtering energy economizer, comprising a casing, wherein a three-phase / single-phase input joint and an output joint are arranged on the casing; coils, iron yokes and three iron cores are arranged in the casing, three iron yokes are connected to the two ends and the middle of each iron core, a coil is arranged on one iron core between two adjacent yokes, and the three iron cores are arranged between the yokes in the same group in parallel. According to the reactance filtering energy economizer, the electric charge is saved by more than 10% since the day when the energy economizer is installed; the voltage and current are maintained under proper state, so that the service life of loading equipment can be prolonged; a current circuit breaker is improved by more than 10% in the tolerance range; a relatively good and stable working voltage is provided for loads; the heat generated by the loading equipment is reduced, and the service life of the loading equipment is prolonged; the power factor of certain equipment is improved; the loading current is reduced, the safety on electricity utilization is increased, and the power supply capacity of a line is increased; the reactance filtering energy economizer is convenient to install, and the electricity utilization habit of a user is not needed to be changed; energy conservation and emission reduction are realized, the concept of electricity saving and energy conservation is changed, and the reactance filtering energy economizer accords with the conceive of 'virtual power plant'.

Description

technical field [0001] The invention relates to energy-saving equipment in a power system, in particular to a reactance filter energy-saving device. Background technique [0002] At present, there are two sources of electrical pollution: (1) When the power system supplies power, the machine will cause two physical phenomena, transient current and surge, resulting in harmonic phenomena on the sine wave (the AC sine wave should be smooth), which is Electricity pollution, wasted electricity is generated from here. (2) When the electricity is transmitted to the enterprise, there will be a small power grid inside the enterprise. The efficiency of the old motor is very poor, and a large number of transient currents and surges are generated, which flow through the small power grid and waste a lot of electricity. In fact, whether it is an enterprise or a general user, the electricity consumption shown on the meter is higher than the actual electricity consumption, and a considerabl...

Problems solved by technology

(2) When electricity is delivered to the enterprise, there will also be a small power grid inside the enterprise. The efficiency of the old motor is very poor, generating a large number of transient currents and surges, which flow through the small power grid, wasting a lot of power

(2) IC circuit voltage automatic control method: the automatic control of the power saver itself exceeds the burden, and only achieves 5% to 6% power saving.

(3) Transformer voltage drop method: because the device that simply drops the voltage causes a large load on the transformer, causing high heat

(5) Vector balance control: each set of machines must be installed correspondingly, which is not practical and expensive for factories with many machines
