Abstract
The invention relates to a water-cooling reactor with an online continuous adjustment function. Cooling water is input into coils wound by copper pipes, so that the section of the coils can be greatly reduced, the effective size of a magnetic core in the coils of the reactor can be changed by smooth lifting of the magnetic core along the axial direction of the coils, so that the reactance value can be adjusted continuously. When alternating-current/direct-current, flat-wave/current-limit reactors are applied to the electric and electronic field, the water-cooling reactor is capable of adjusting the reactance value thereof, particularly suitable for places requiring online continuous adjustment of the reactance value and is universal for single phase and three phases and has the advantages of simple structure, small size, low manufacturing cost and high reliability.
Description
Technical field
When the present invention relates to field of power electronics and using ac/dc, flat ripple/current limiting reactor, the occasion that need regulate the reactor value of reactor is a kind of REgulatable reactor.
Background technology
Present conventional REgulatable reactor basically all is to have a plurality of centre taps.When system need change reactance value, need to have a power failure and switch the reactor tap.The shortcoming of doing like this is that inconvenient operation, cost of manufacture are high, and reactance value is discontinuous.Magnet controlled reactor is also arranged, but this method makes that system bulk is big, cost is high, power consumption is big, and reliability is very poor.
Summary of the invention
But the water cooling reactor that the present invention provides a kind of on-line continuous to regulate can change the volume of magnetic core in the reactor winding through manual or electric operating up-down actuator, to reach the purpose of regulating reactance value.Simultaneously, adopt copper pipe to come coiling, the copper pipe the inside passes to cooling water.That such reactor has is simple in structure, advantages of small volume, cheap, advantage that reliability is high, but especially on-line operation, reactance value is adjustable continuously.
For realizing above-mentioned purpose, technical scheme of the present invention is: but the water cooling reactor that on-line continuous is regulated comprises coil (1), magnetic core (2), support (3), guide rail (5), leading screw (6), shaft coupling (7), torque motor and reduction box (8); Coil forms for the copper pipe coiling, passes to cooling water in the copper pipe, and support is an insulating material, and torque motor connects leading screw through shaft coupling, drives magnetic core along the axial operation of smoothly going up and down of coil by leading screw and guide rail, changes the effective volume of coil inner magnetic core.Wherein, leading-out terminal (4) also will insert the cooling water of being introduced by insulated tube when connecing electrical source of power, reduce the sectional area of coil so greatly, and magnetic core is a soft magnetic material, support fixed end taken about the point of fixation motor, reduction box and coil.Direct current torque motor has the function of lock shaft after rotating, the dead electricity, and the axle of reduction box links to each other with leading screw through shaft coupling, and the center of magnetic core is furnished with nut, and leading screw is screwed into nut, and then magnetic core is realized up-down under the effect of leading screw and guide rail.The axial length of magnetic core is not less than the axial length of coil; The stroke that magnetic core goes up and down is not less than the axial length of magnetic core; Rotation along with torque motor; Relative position between coil and the magnetic core changes, thereby reaches the purpose of regulating reactance value: reactance value is maximum when all being full of magnetic core in the coil; When magnetic core broke away from coil fully, reactance value was minimum.Torque motor and decelerator also can change hand-operated mechanism into, and they make magnetic core slowly smoothly to go up and down, thereby make the continuous variation of reactance value, and the up-down of magnetic core operation can on-line operations through the operation of leading screw to magnetic core.That this method is common to is single-phase, the operating position of three-phase reactor.
When but the magnetic core of the water cooling reactor that on-line continuous according to the invention is regulated was concordant with coil bottom, reactance value was maximum, and the operation hoisting mechanism makes magnetic core progressively promote, and reactance value also decreases, and when magnetic core was pulled out to outside the coil fully, reactance value was minimum.The present invention is simple in structure, and is easy to operate, can realize the online smooth adjustment of reactance value through regulating the relative position of magnetic core and coil.
Description of drawings
Fig. 1 is the structural representation of the preferred embodiment of the present invention, and magnetic core is concordant with coil bottom, the state that reactance value is maximum;
Fig. 2 is the structural representation of the preferred embodiment of the present invention, and magnetic core is in the lifting process, the state of reactance value a certain value between minimax;
Fig. 3 is the structural representation of the preferred embodiment of the present invention, and magnetic core is pulled out outside the coil fully, the state that reactance value is minimum;
Fig. 4 removes support and hoisting mechanism, the vertical view of surplus coil and magnetic core only for the present invention.
Embodiment
The present invention is carried out bright specifically below in conjunction with concrete embodiment.
Like Fig. 1, Fig. 2 and shown in Figure 3, but the water cooling reactor that a kind of on-line continuous is regulated comprises coil (1), magnetic core (2), support (3), leading-out terminal (4), guide rail (5), leading screw (6), shaft coupling (7), torque motor and reduction box (8); Coil is formed by the copper pipe coiling; Also will insert cooling water in the time of the leading-out terminal external wire, magnetic core is a soft magnetic material, stent support coil, torque motor and reduction box; The axle of reduction box links to each other with leading screw through shaft coupling; Magnetic core closes at leading screw under the effect of guide rail, along with the positive and negative of motor then make lifting action, thereby regulates the reactance value of reactor continuously.Adjustment process can onlinely be carried out.Single-phase, three-phase situation that this method is common to.Only get final product the reactance value that on-line continuous is regulated water cooling reactor, have advantage simple in structure, easy to operate, cheap, that reliability is high through the position that changes magnetic core.
