Description
Technical field
The invention belongs to reactor, be particularly applicable to the Controlled Reactor of low pressure static reactive equipment.
Background technology
Usual low voltage dynamic reactive-power compensation mainly adopts thyristor switch to carry out quick-switching capacitor (being called for short TSC), and its response speed the soonest can within 40mS.But because it belongs to step evolution switching, its compensation precision is not high, in order to avoid inrush phenomenon and switching overvoltage are to the impact of reverse-blocking tetrode thyristor and capacitor, need to detect through zero passage transitional processes before every group capacitor switching, require high to control testing process, in the system that some on-the-spot harmonics level are higher, often there is the situation that reverse-blocking tetrode thyristor or capacitor batch damage.In recent years, the static passive compensation device of low pressure started to be applied, and its control core is phased iron core reactor (thyristor control linear reactor is called for short TCR), has got good dynamic passive compensation effect.Iron core reactor magnetic field forms loop by iron core and air gap, and whether its inductance value linearly depends on the magnetic field operating state of iron core.When magnetic saturation appears in iron core, then will there is nonlinear change in air gap internal magnetic field, cause inductance non-linear, and had influence on silicon controlled Linear Control, in order to prevent this situation, it is larger that the iron core of general phased iron core reactor and volume do, and cost is very high.In addition, the magnetic hysteresis that also there is iron core is stretched the noise problem caused, and Heavy Weight, assembling are complicated, can not the problem such as direct outdoor use.And phased air core reactor due to volume excessive, the problem that external leakage field is serious, loss is excessive, cannot be directly installed in low pressure cabinet, is unsuitable for the dynamic compensating device of low pressure.
Summary of the invention
Poor in order to solve existing phased iron core reactor control linear, cost is high, Heavy Weight, the problem that noise is large and phased air core reactor volume excessive, external leakage field serious deficiency, the object of this invention is to provide a kind of phased half-iron-core reactor of low pressure for low pressure static reactive equipment, this phased half-iron-core reactor of low pressure being used for low pressure static reactive equipment is in conjunction with the advantage of air core reactor and iron core reactor, not only can accomplish that volume is little but also inductance can be made linear in a big way, can be arranged in low pressure cabinet or be directly used in open air.
The technical solution adopted for the present invention to solve the technical problems is: a kind of phased half-iron-core reactor of low pressure for low pressure static reactive equipment, it is characterized in that: Controlled Reactor adopts semi-core type structure, form by coil with containing an iron leg core in coil, the annular core be arranged between interior insulating cylinder and external insulation cylinder is made up of radiation lamination, iron core upper and lower side is perfused with insulation filler, wedging end, interior insulating cylinder two ends briquetting, the reactor winding of encapsulated type structure is provided with outside iron core, insulated end portions briquetting is adopted to realize the fixing colligation of coil and iron core and the mechanical connection with insulator, coil in encapsulating holds to fill through insulation and forms entirety, encapsulating end and iron core upper, bottom is filled to ramped shaped by insulation filler, heat radiation air flue is had between encapsulating, each coil lead be connected to be positioned at upper and lower end parts briquetting side binding post on.
The described end briquetting being positioned at lower end is fixed on lower margin by insulated support, insulator.
Reactor winding adopts encapsulated type structure, adopts insulation pressing to realize the fixing colligation of coil and iron core and the mechanical connection with insulator.Coil in encapsulating holds to fill through insulation and forms entirety, to resist outside atmospheric environment.The upper end of encapsulating end and iron core is filled to ramped shaped by insulation filler, prevents rainwater, dirt accumulation.In order to satisfied heat radiation, between encapsulating, there is heat radiation air flue, encapsulating is split mutually with encapsulating.Inner-core adopts annular core, radiation lamination, and is cast between inside and outside two insulating cylinders, and iron core is sealed completely.The outdoor scene end of iron core adopts circular arc or broken line shape, avoids end to occur wedge angle, prevents iron core from occurring local magnetic saturation phenomenon.Insulating cylinder wedging end briquetting inside iron core, thus ensure that iron core is not shifted when operation or fault.The coil of semi-core type reactor and iron core are all in epoxy insulation thing and insulation filler sealed envelope, coil and iron core and external environment completely isolated.Iron core is only equivalent to an encapsulating of air core reactor.Product closely has mechanical connection between line terminal and end briquetting, and remainder is formed overall after solidification, and therefore, the mechanical property of half-iron-core reactor is very excellent.
Half core Controlled Reactor can regard the reactor between air core reactor and iron core reactor as, and its performance too between.Relative to air, the relative permeability of iron core is more than tens times of air, and the inductance of semi-core type reactor still linearly.Because iron core is only to the short circuit of part magnetic circuit, the magnetic control in iron core is lower, not easily occurs magnetic saturation, so the linearity of semi-core type reactor will due to iron core reactor.The contrast of the linearity of semi-core type Controlled Reactor and hollow, iron core reactor, loss, noise, leakage field, volume, weight, occupation of land, cost, mounting means, environment for use, sees the following form.
| The linearity | Loss | Noise | Leakage field | Volume | Weight | Take up an area | Cost | Mounting means | Environment for use | |
| Air core reactor | Excellent | Greatly | Little | Greatly | Greatly | Little | Greatly | Little | Independent installation | Outside indoor |
| Iron-core reactor | Good | Little | Little | Slightly large | Little | Heavy | Little | In | In level, cabinet | Outside indoor |
| Half-iron-core reactor | Difference | Little | Appropriateness | Little | Little | Heavy | Little | Do | In fixing, cabinet | Indoor |
The invention has the beneficial effects as follows, semi-core type mechanism, form by coil with containing an iron leg core in coil, there is the advantage of iron core reactor and air core reactor, not only can accomplish that volume is little but can make inductance linear in a big way, can be arranged in low pressure cabinet or be directly used in open air, relative iron core reactor cost is lower.
