Technical field
The utility model relates to a kind of device of technical field of power systems, specifically is that a kind of magnet controlled reactor triggers control device.
Background technology
Magnet controlled reactor (MCR) mainly is made up of magnet controlled reactor body, trigger control module and controller.The magnetic circuit of magnet controlled reactor is " valve formula " structure, and its iron core is in series by area bigger part and the less part of area.The direct current size is level and smooth in the trigger control module control winding changes small size degree of saturation unshakable in one's determination, thereby changes reactance value and reactor output capacity.The magnet controlled reactor major function is: (1) absorption system surplus is idle, keeps idle in-situ balancing; (2) reduce voltage fluctuation, systems stabilisation voltage; (3) can realize imbalance compensation, reduce the negative-sequence current of loading; (4) can raise by confinement end voltage in the extra high voltage network, guarantee equipment safety operation.Magnet controlled reactor use in parallel with the capacitor group can realize the real-time dynamic compensation of reactive power.Magnet controlled reactor control winding is come out by a direct tap of winding, adopts the self coupling power-supply rectifying to obtain the needed direct current of control.Between winding and the homophase core limb, the direct current size was exported in control about controllable silicon and diode (led) module were connected across.Because controllable silicon and diode are directly hung high potential, it triggers power supply and obtains with the trigger impulse transfer ratio difficult.Conventional method adopts pulse transformer to isolate triggering or passes through to increase assist control winding mode.Adopt pulse transformer to isolate and trigger to exist volume big, poor anti jamming capability causes false triggering easily, influences system reliability.Increase the assist control winding, not only increase magnet controlled reactor volume and cost, also increase the reactor running wastage.
Summary of the invention
The utility model is at the deficiencies in the prior art, provide a kind of magnet controlled reactor to trigger control device, for magnet controlled reactor provides safe and reliable triggering power supply and trigger impulse transmission means, solve power supply and pulse high potential isolating problem, effectively reduce the reactor manufacturing cost, guarantee that controllable silicon reliably triggers.
The utility model is achieved through the following technical solutions, and the utility model comprises: binding post, fast acting fuse, controllable silicon, diode, radiator, triggering drive plate, optical fiber, temperature detect switch (TDS), fan, support, shell, insulation column and RC absorption circuit.Binding post is connected with fast acting fuse, fast acting fuse is connected with controllable silicon, diode respectively, controllable silicon, diode, RC absorption circuit, temperature detect switch (TDS) and triggering drive plate are arranged on spreader surface, radiator integral is fixed in support and the shell, optical fiber is connected with the triggering drive plate, trigger drive plate output and connect the controllable silicon gate pole, temperature detect switch (TDS) is connected in the fan power supply loop, directly held against heat sink setting, fan is arranged on the radiator downside, and its power supply is in parallel with triggering drive plate power supply.The device insulation against ground, by the insulation column support fixation, device integral body is in high potential.
The utility model magnet controlled reactor triggers control device and installs and uses near the magnet controlled reactor coil.Binding post always has 5, first terminal connects fast acting fuse, connect the silicon controlled anode A by fast acting fuse again, silicon controlled negative electrode K directly connects second binding post, the 3rd terminal connects the another one fast acting fuse, connected the anode A of diode again by this fast acting fuse, the negative electrode K of diode connects the 4th binding post, the power supply input of the 5th binding post and second binding post constituent apparatus.
Trigger drive circuit power supply powerup issue for solving controllable silicon, the utility model adopts the structure and the working method of magnet controlled reactor main winding tap power taking, integral insulation.Take out certain number of turn coil from magnet controlled reactor body winding and draw tap, when reactor powered on, tap voltage was about alternating current 220V.Tap of power supply another one and SCR control winding are shared, because about silicon controlled rectifier voltage 200V, maximum voltage difference is about 420V in the module like this, general insulated conductor can meet the demands.Power supply is used for to triggering the power supply of drive plate and radiator fan.When radiator temperature height to 60 ℃, temperature detect switch (TDS) node closure, starting fan dispels the heat.Because this alternating current 220V has high potential (suitable with system voltage) over the ground, so all circuit that power supply links all are to be in high potential, comprises shell.Whole device adopts integral insulation pillar mounting means to support and is fixing.Owing to be overall isolation, circuit board power transformer T1 uses withstand voltage 2000V typical transformer to get final product.Cause that for preventing the fan short circuit and triggering the drive plate internal short-circuit fault enlarges, the 5A fuse is installed in the alternating current 220V loop.Adopt the structure of magnet controlled reactor main winding tap power taking, module whole insulation to solve controllable silicon triggering isolating problem, compare, saved installing space and volume greatly, and reduced whole cost, improved reliability with adding isolating transformer.
For solving the trigger impulse transmission problem, the utility model adopts optical fiber to isolate and the constant-current source triggering mode.Controller sends the trigger impulse of respective angles according to the three-phase synchronizing voltage, and conversion becomes light pulse and enters optical fiber through electric light.Because optical fiber is non-conductive, has insulating effect, this light signal enters the triggering drive plate through optical fiber, is reduced to electric pulse through after the opto-electronic conversion again, becomes the trigger current source after the further processing and amplifying of this electric impulse signal controllable silicon is triggered.Compare with existing pulse transformer triggering controllable silicon mode, adopt winding power supply, optical fiber to isolate the strong triggering mode of constant current and have advantages such as volume is little, reliability is high, the triggering dispersiveness is little.This mode had both solved the high potential controllable silicon and had triggered isolating problem, had strengthened anti-interference again, had further improved the triggering performance.
The utility model adopts the power taking of reactor body, optical fiber to isolate triggering mode, and adopts the constant-current source hard pulse that controllable silicon is triggered, and is simple in structure, reliable trigger, and antijamming capability is strong.
