It is shown.1Q, 2Q, 3Q in Fig. 2 are breaker, and normality is closing position, are mainly used in carrying out short circuit and overload protection, 1KM,
2KM is contactor, is mainly used in alternating current circuit control；GTO is turn-off thyristor, and its triggering and conducting is made with gate pole positive signal,
Turned it off with gate pole negative signal, be mainly used in DC circuit control.GTO rated current (i.e. anode can cut-off current most
Big value IATO) should be by 3 times of selections not less than load current, the rated voltage (i.e. anode peak voltage Vp) of GTO should be by not small
In 2 times of selections of line voltage distribution；The DC input voitage of inverter is identical with the DC voltage that battery charging and discharging panel is provided, and its exchange is defeated
Depending on going out voltage and capacity by AC load.In Fig. 2, during main distribution board normal power supply, contactor 1KM automatic picks, contact
Device 2KM is blocked, and AC load is directly powered by main distribution board；During main distribution board dead electricity, contactor 1KM is automatically releasable, and is answering
Before anxious panel is not yet powered (about 30 seconds or so time), GTO triggering and conductings are made with gate pole positive signal, provided by battery charging and discharging panel
Dc source becomes AC power and is powered to AC load through inverter；After emergency switchboard starts power supply, contactor 2KM is certainly
Dynamic adhesive, contactor 1KM is blocked, while turning off GTO with gate pole negative signal, AC load is directly supplied by emergency switchboard
Electricity；When main distribution board and emergency switchboard all dead electricity, contactor 1KM, 2KM are automatically releasable, and the gate pole of GTO controllers 1 is just

After main distribution board or emergency switchboard restore electricity, contactor 1KM or 2KM automatic pick, while GTO controllers 1 use gate pole
Negative signal turns off GTO, and AC load is directly powered by main distribution board or emergency switchboard.
The utility model has that three tunnels are interactive and two-way is interactive, three tunnel interactions refer to main distribution board power main power source,
The public direct current power supply that the emergency power supply and battery charging and discharging panel that emergency switchboard is powered are powered is interactive, and its control principle is as previously described.
Two-way interaction refers to that the public direct current power supply that the emergency power supply that emergency switchboard is powered and battery charging and discharging panel are powered is interactive, such as Fig. 3 institutes
Show.
The specific embodiment one of GTO controllers 1 is as shown in figure 4, when main distribution board and emergency switchboard all dead electricity, contact
Device 1KM, 2KM are automatically releasable, and its normally closed auxiliary contact is connected, positive supply through resistance R and normally closed auxiliary contact 1KM, 2KM extremely
GTO gate poles, produce positive current to make GTO triggering and conductings, while energy storage is carried out to inductance L, the direct current for now being provided by battery charging and discharging panel
Power supply becomes AC power and is powered to AC load through inverter；After main distribution board or emergency switchboard restore electricity, contact
Device 1KM or 2KM automatic pick, its normally closed auxiliary contact 1KM or 2KM disconnect, and the electric energy being stored in L discharges negative electricity and flow to
GTO gate poles are turned it off, and now AC load is directly powered by main distribution board or emergency switchboard.During using which, great Rong
The GTO of amount requires larger inductance L to produce larger storage energy.
The another specific embodiment one of GTO controllers 1 is as shown in figure 5, when emergency switchboard is powered, contactor KM inhales automatically
Close, AC load is directly powered by emergency switchboard；When emergency switchboard dead electricity, contactor KM is automatically releasable, and its is normally opened auxiliary
Contact KM is helped to disconnect, positive supply charges through resistance R to capacitor C, producing positive electricity to flow to GTO gate poles makes its triggering and conducting, by filling
Discharge electrode offer dc source becomes AC power and is powered to AC load through inverter；When emergency switchboard restores electricity,
Contactor KM automatic picks, its normally opened auxiliary contact KM closure, capacitor C electric discharges, producing negative electricity to flow to GTO gate poles closes it
Disconnected, AC load is directly powered by emergency switchboard.Adopt when in this way, if GTO drives capacity larger, it is required that capacitor
Capacity it is also larger.
The parameter determination that the signal of GTO door-plate triggering and conductings can be provided by GTO products, typically require trigger voltage for 3-
15V, trigger current is tens to hundreds of milliamperes.
It is to characterize a strong and weak important spy of GTO turn-off capacities that one important parameter of GTO is off gain beta off, β off
Levy, β off are equal to the ratio between the maximum anode current IATO being turned off negative current-IGM maximum with gate pole, i.e.,：
β off=IATO/ |-IGM ︱
β off are several times to tens times.β off values are bigger, illustrate that gate current is stronger to the control ability of anode current.
The brand and size of current of GTO can all have an impact to β off, in physical circuit, should according to the parameter determination resistance of GTO products,
The parameter of the elements such as electric capacity.
Another important parameter of GTO is latching current, and latching current refers to just to be transferred to on-state from off-state and cut off gate pole
After electric current, the minimum anode current needed for on-state can be maintained.To prevent the dc source provided by battery charging and discharging panel through inverter
When becoming AC power and being powered to AC load, load current causes GTO voluntarily to turn off less than latching current, the utility model
In load-side compensating electric capacity module in parallel, can not only prevent GTO from voluntarily turning off, and can prevent by the electric discharge of capacitor
The of short duration power-off for occurring only is possible in interactive process, while power factor can be improved.The capacity of compensating electric capacity module can be by negative
10-15% selection of capacity is carried, depending on its capacitive reactance is than the harmonic wave by being likely to occur.
In addition to the implementation, the utility model can also have other embodiment, all use equivalents or equivalent change
The technical scheme to be formed is changed, is all fallen within the protection domain of the utility model requirement.
