Abstract
The invention discloses a magnetically-controlled reactive load box which comprises a box body, wherein a current transformer, a control device, an excitation device and a magnetically-controlled reactor are arranged in the box body; the current transformer is externally connected with a test switch and internally connected with the control device and the excitation device; and the excitation device is connected with the magnetically-controlled reactor. The magnetically-controlled reactive load box has the benefits as follows: the reactive load box adopting a magnetically controlled reactor control manner directly adopts a magnetically-controlled reactor control device for control, and requirements for device accuracy, reliability, safety, quick reaction capability, small size, simplicity in mounting and low operating cost can be met.
Description
Technical field
The present invention relates to electrical equipment technical field, particularly relate to a kind of magnetic control reactive load case.
Background technology
At present, two kinds of the existing reactive load case fixed reactor of inner employing or adjustable reactors.Fixed reactor because of capacity be certain value, dirigibility is poor, range of application is narrow.REgulatable reactor governing speed is slow, regulate the deficiencies such as unsmooth, three-phase equilibrium degree is poor, cost is high, volume is large, automaticity is poor, increases user's buying expenses, maintenance cost, erected cost, and complicated operation in use is very inconvenient.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of magnetic control reactive load case, this load box has that output harmonic wave is little, low in energy consumption, non-maintaining, simple in structure, reliability is high, cheap, floor area is little, its inner for full static structure, movement-less part, functional reliability high, and this device performance is stable, life-span is long, the advantages such as non-maintaining after putting into operation, overload capacity is strong, and range of adjustment is wide, reaction velocity is fast.
The technical solution adopted in the present invention is: a kind of magnetic control reactive load case, comprise casing, in casing, comprise current transformer, control device, excitation unit, magnet controlled reactor, the external Test Switchboard of described current transformer, inside connect control device and excitation unit, excitation unit connects magnet controlled reactor.
As preferably, described casing is provided with control button, controls button and connects control device.
Compared with prior art, the invention has the beneficial effects as follows: the reactive load case of magnet controlled reactor control mode, directly adopt the control of magnet controlled reactor control device, can meet the precision of equipment, reliability, security, quick-reaction capability (QRC).Volume is little, installs simply, and operating cost is low.
Brief description of the drawings
Fig. 1 is structural drawing of the present invention.
In figure: 1. current transformer, 2. control device, 3. excitation unit, 4. magnet controlled reactor.
Embodiment
In order more clearly to understand technical scheme of the present invention, below in conjunction with accompanying drawing, the present invention is further described.
A kind of magnetic control reactive load case as shown in Figure 1, comprise casing, in casing, comprise current transformer 1, control device 2, excitation unit 3, magnet controlled reactor 4, the described external Test Switchboard of current transformer 1, inside connect control device 2 and excitation unit 3, excitation unit 3 connects magnet controlled reactor 4, described casing is provided with control button, control button and connect control device 2, load power source flows to excitation unit 3 through current transformer 1, control device 2 is according to the current value presetting, automatically control excitation unit 3, excitation magnet controlled reactor 4 magnetic fluxs, and then adjusting magnet controlled reactor 4 amount of capacity, so that reach the electric current that will load.Current signal access control apparatus 2 in this structure, the electric current obtaining by sampling and the current value ratio presetting, increase or reduce the magnetic flux density of reactor, automatically with the size of magnet controlled reactor electric current according to the size of sample rate current.Adopt excitation system to change the mode of magnet controlled reactor magnetic flux density, change rate of current fast, precision is high, and good stability can regulate arbitrarily in range of capacity.
The above is only preferred embodiments of the present invention, and the equivalence of doing according to structure, feature and principle described in patent claim of the present invention therefore all changes or modifies, and is included in patent claim of the present invention.
