Abstract
The utility model discloses a drawer modular active power filtering device, which comprises a breaker, a fuse, a contactor and a soft start resistor. The soft start resistor is connected in parallel with the contactor to be used as a controllable switch, a connecting copper busbar of the contactor is divided into three branches, namely an AN phase, a BN phase and a CN phase, each branch has two buses, and installing holes are arranged on the copper busbar to be connected with a module. Each power module adopts drawer structure design, a guide track is arranged on an interface circuit, each power module can be drawn out in back and front directions, and a radiating fan is arranged on top of each power module. The drawer modular active power filtering device has functions of traditional active filters, is convenient for production, suitable for installing, flexible in capacity selection and adaptive to large-scale production and processing.
Description
Technical field
The utility model relates to a kind of active filter, in particular to a kind of drawer type modular active electric filter device.
Background technology
Along with the extensive use and the development of power electronic technology, the nonlinear load in the electric power system is increasing, like rectifier, frequency converter, UPS, household electrical appliance and computer etc.These nonlinear loads can produce harmonic current and be injected in the electrical network, make the voltage waveform in the electrical network produce distortion, thereby cause the harmonic pollution of electrical network.In addition, impact, fluctuating load, being in operation like arc furnace, welding equipment etc. not only can produce a large amount of high order harmonic components, and makes voltage fluctuation, flickering, three-phase imbalance serious day by day, the safe operation of harm electrical network.
And the perfect way that solves power quality problem at present is an active filter.Active filter not only can be eliminated the harmonic wave of the overwhelming majority in the electric power system, and reactive power can be provided, and suppresses voltage flicker, and the balance three-phase is the comprehensive treatment device of the quality of power supply.Yet the traditional active filter is structural load together, is difficult for producing and processing, and construction is also comparatively complicated.Be unfavorable for the large-scale production of active filter and popularize.
The utility model content
The utility model purpose is:
A kind of drawer type modular active electric filter device is provided, different with traditional active filter structure, adopt the parallel single-phase pattern, by unified controller control, convenient, flexible then, be fit to produce and construction.
The utility model adopts following technical scheme for realizing above-mentioned purpose:
A kind of drawer type modular active electric filter device is characterized in that: comprise circuit breaker, fuse, contactor, soft start resistance, power model; Soft start resistance is connected in parallel on the contactor as controlled switch, and contactor connects copper bar and is divided into 3 the tunnel, two on every road; Being divided into is the AN phase, BN phase, CN phase; Leave installing hole on the copper bar, in order to the linking of power model, each power model adopts drawer-type structure design; Interface circuit is equipped with guide rail, can on fore-and-aft direction, power model be extracted out, and radiator fan is equipped with at the top.
The drawer type modular active electric filter device of technique scheme can be made up of 3～18 power models; Each power model all is connected in parallel on the bus of device, does not influence each other.
Above-mentioned drawer type modular active electric filter device gets final product on construction the time only need be directly installed on power model the interface circuit of device; Each power model is realized Comprehensive Control by the controller control of interface circuit.
The power model mounting means of this device adopts the drawer-type structure design, and interface circuit is equipped with guide rail, can on fore-and-aft direction, power model be extracted out.
The control strategy of power model is: the detection system electric current, isolate its first-harmonic and idle composition, and the electric current of output and system harmonics and idle composition anti-phase, thus reach the purpose of filtering harmonic compensating reactive power.
The beneficial effect of the utility model is:
1,2 to 60 subharmonic in can the filtering power distribution network of dynamic real-time, the system's reactive power of can instantaneously handling up continuously improves the quality of power supply, guarantees the power consumer Electrical Safety, and energy savings is brought direct economic and social benefits.
2, this structure has realized the modularization of device, and each power model is relatively independent, only need module be directly installed on the interface circuit of device during construction to get final product.Flexible operation is easy to install and maintenance.
Description of drawings
Fig. 1 is a drawer type modular active electric filter device overall structure sketch map;
Fig. 2 is the interface circuit of drawer type modular active electric filter device.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, further illustrate the utility model;
Shown in accompanying drawing 1, accompanying drawing 2, drawer type modular active electric filter device interface circuit is made up of 18 power models;
Drawer type modular active electric filter device interface circuit comprises circuit breaker, fuse, contactor; Soft start resistance is connected in parallel on the contactor as controlled switch, and contactor connects copper bar and is divided into 3 the tunnel, two on every road; Being divided into is the AN phase, BN phase, CN phase; Leave installing hole on the copper bar, in order to the linking of module, radiator fan is equipped with at the top.
The power model mounting means of this device adopts the drawer-type structure design, and interface circuit is equipped with guide rail, can on fore-and-aft direction, power model be extracted out.
It is relatively independent that this structure is compared each power model with the traditional active filter, only need module be directly installed on the interface circuit of device during construction to get final product; Compare with original modular active filter, each module has realized Comprehensive Control by the controller control of interface circuit, is the optimization to the modular active filter.
