Abstract
An intelligent energy-saving apparatus of harmonic reactive power compensation used in oil field system solves the problem of the present compensation apparatus that the harmonic reactive wave in electric network can not be removed, and is characterized in that power terminals (A, B and C) are connected with the input end of the controller (1) in a shell body(U#-[A],U#-[B] and U#-[C]); a plurality of harmonic wave modules consist of a first series connection, a second parallel connection of a silicon controlled rectifier(V), an inductor (L), and a capacitor (C); a plurality of common compensation modules are composed of the parallelly connected the silicon controlled rectifiers(V) which are also connected with a three-phase capacitive (C1); the output end of the controller (1) is connected with the control pole of the silicon controlled rectifier(V) in the harmonic reactive wave modules and the common compensation modules; a current transformer is connected with the terminals of the controller (1) (I#-[0],I#-[A],I#-[B] and I#-[C]). The utility model can remove the harmonic waves of the grid and reach the industry standard, prevents the automatic instruments in the system from loss of control, reduce the overhaul workload and the costs, achieve the safety and reliability, and meet the requirement of environment protection.
Description
Technical field:
The utility model relates to a kind of energy saver that oil field system uses, and belongs to harmonic elimination wave mode reactive power compensation energy saver.
Background technology:
Field produces is used a large amount of motors at present, consumes a large amount of electric energy, and facilities such as the energy-conservation cabinet of conventional use install by way of compensation to reach energy-saving effect.Can in use generally can not eliminate mains by harmonics with compensation arrangement owing to existing, and sometimes harmonic current be amplified, cause the automation instrument in the network system out of control, increase maintenance workload, in case instrument and meter damages, just cause cost to raise, have a strong impact on the oil field ordinary production.
Summary of the invention:
Can not eliminate the deficiency of mains by harmonics in order to overcome existing compensation arrangement, the utility model provides a kind of harmonic elimination wave mode reactive power compensation energy saver, this device can be in use can harmonic carcellation, good stability.
Technical solution adopted in the utility model is: this harmonic elimination wave mode reactive power compensation energy saver, comprise power supply terminal and housing, power supply terminal connect the housing internal controller input and some by the harmonic elimination mode piece that composes in parallel again after controllable silicon, inductance and the capacitances in series, somely connect the common complementary modulus piece that the three phase capacitance terminal composes in parallel again respectively, and the output termination harmonic elimination mode piece of controller and the silicon controlled control utmost point in the complementary modulus piece altogether by controllable silicon; And power transformer connects the terminal of controller.
Above-mentioned harmonic elimination mode piece is four, and the complementary modulus piece is two altogether.
The beneficial effects of the utility model are: because this device is made up of some harmonic elimination mode pieces and common complementary modulus piece, when making on-the-spot the use, the harmonic wave of electrical network can be eliminated, reach industry standard, do not cause intrasystem automation instrument out of control, maintenance workload significantly reduces, and cost descends, safety, reliable reaches environmental protection requirement.
Description of drawings:
Accompanying drawing 1 is the wiring schematic diagram in the utility model housing.
Embodiment:
The utility model is described in further detail below in conjunction with accompanying drawing:
In conjunction with the accompanying drawings shown in 1, this harmonic elimination wave mode reactive power compensation energy saver comprises that (C) and housing, (A, B C) connect the input (U of housing internal controller 1 to power supply terminal to power supply terminal for A, B
A, U
B, U
C), so that power supply in time, and be composed in series harmonic elimination mode piece by controllable silicon V, inductance L and capacitor C in the housing, but the control of controllable silicon V extremely must connect the output of controller 1 in the harmonic elimination mode piece, can eliminate simultaneously the harmonic wave of electrical network, energy-conserving and environment-protective, good stability reaching the reactive power compensation purpose.Harmonic elimination mode piece can be formed together for some groups according to actual conditions, better effects if, generally being set at four groups at Daqing oil field at present gets final product, the value of controllable silicon V, inductance L and the capacitor C of each group can according to circumstances be selected, the extremely corresponding output that connects controller 1 of the control of each controllable silicon V; And controllable silicon V has promptly formed common complementary modulus piece after connecing three phase capacitance C1 terminal respectively, being chosen to be two gets final product, the control utmost point of the interior controllable silicon V of complementary modulus piece connects the output of controller 1 altogether, compensating power, better effects if does not cause intrasystem automation instrument out of control, and maintenance workload significantly reduces, cost descends, and is fit to apply.
And the output termination current transformer of controller 1 meets the terminal (I of controller 1
O, I
A, I
B, I
C), identical during actual the use with existing energy saver, only existing energy saver is replaced to this utility model and get final product.
