The utility model comprises the tapped control transformer of a primary coil and a voltage-stabilizing control device composed of an integrate electronic device and a relay. The primary coil and a secondary coil are independent mutually. When the input voltage of the electric network changes within a certain limit, the output controlling, lighting and signal voltage can be stabilized within the range required by electric equipment for machine tools, such as an alternating current contactor, etc. through the secondary output voltage under the action of the voltage-stabilizing control device. The utility model has the advantages of simple circuit, few devices and compact structure.
Description
The utility model belongs to Machine Tool Electric Appliance, and a kind of specifically conversion lathe exchanges the device of control, illumination, signal voltage.
The control transformer that uses in the existing domestic various controls of lathe, illumination, the signal circuit does not all have voltage stabilizing function and (sees lathe auxiliary equipment sample P662, the P663 of Beijing Machine Tool Inst.'s establishment.Version in 1987).So when the control transformer primary voltage when off-rating 90% changes outside 110%, secondary voltage is also along with variation.So can not guarantee the operate as normal of various Machine Tool Electric Appliances (as A.C. contactor, auxiliary reclay etc.).Commercially available in addition family expenses ac automatic voltage regulator since transformer at the beginning of, secondary coil is same winding, on high-tension side voltage failure directly influences low-pressure side, and the voltage usable range, precision of voltage regulation aspect is former thereby can not use on lathe.
The purpose of this utility model is to provide a kind of AC stabilizer of making to stablize control, illumination, signal circuit voltage in various Machine Tool Circuits to the public.
Technical solution of the present utility model is: be used for the conversion lathe and exchange control, illumination, the voltage stabilizing control transformer accompanying drawing 1 of signal voltage, a voltage-stabilizing controller (1) is arranged, also has a control transformer (2), when voltage-stabilizing controller (1) is exactly the utility model with control transformer (2) after lead is connected both sides' associated end, the winding primary and secondary that it is characterized in that control transformer (2) is separate, and elementary winding has 5 taps at least, described tap all is connected between the relay contact of voltage-stabilizing controller (1), logical circuit in the voltage-stabilizing controller (1) is made up of gate circuit and sample circuit, driving circuit is formed by driving integrated package and two relays at least, rectification circuit is made up of two groups of bridge heaps: wherein the B1 in the control transformer (2) is the induction type transformer of elementary band tap, V1-4 in the voltage-stabilizing controller (1), C1, W, C2 forms the 5V D.C. regulated power supply, so that the operating voltage of 01-09 not gate and Sheffer stroke gate to be provided.V5-8, C3, R9 form the 24V rectification circuit, to provide integrated drive MC, the working power of relay J 1, J2, J3.V3-5 is respectively the back-emf absorption diode of J1-3.R7-8 forms power supply sampling bleeder circuit, and V9-12, R1-6 form sampling and divide voltage rectifier, so that the power supply sampling voltage of the gate circuit of being made up of 01-09 to be provided.
Input voltage of the present utility model is 110V, 220V, 380V, 440V, 660V, and output voltage is 6.3V, 12V, 24V, 48V, 110V to 220V under zero load or load, and the precision of voltage regulation is ± 7%.
Output capacity of the present utility model is 10VA to 2000VA.
Advantage of the present utility model and good effect are:
1, voltage adaptation wide ranges, its voltage adaptation scope of the utility model is 68% to 115% of an input voltage ratings.
2, behind use the utility model, A.C. contactor, industrial electrical equipments such as auxiliary reclay exceed its usable range (especially in summer harvesting and sowing and drought resisting season) and make contactor electromagnet produce vibration to blow contact or melting welding or burn magnet coil and will get with the phenomenon that causes burn-down of electric motor and eliminate owing to mains fluctuations exceed fluctuation.And saved several ton valuable silver alloy for country every year.The shutdown loss that machine tool is caused owing to the voltage fluctuation reason gets to be eliminated.
Besides the A.C. contactor of annual domestic new production, auxiliary reclay just has 1,000 3 one hundred ten thousand, adds original contactor on machine tool, 6,000 ten thousand of solenoids such as relay.If annual just have 3,650,000 because voltage fluctuation is former thereby quantity that burn accounts for 5% of 2 sums, can be country every year with 40 yuan every valuation and economize on the use of funds 1.46 hundred million yuans.
3, application prospect is extensive.Because 611 regulations of Machine Tools Electric Device-General technical conditions BG5226-85 standard; For lathe, must adopt the transformer that separates winding to give control and signal circuit power supply with 5 above solenoids.Again soon with 911 regulations of People's Republic of China's Electrical equipment of industrial machines general technical specifications (exposure draft replaces Machine Tools Electric equipment GB5226-85 standard) of using, control circuit application of power transformer-supplied.Transformer must be an independent winding.So the utility model use prospect is widely.
Concrete structure of the present utility model is described further in conjunction with the embodiments.
Fig. 1 is a schematic diagram of the present utility model.
Fig. 2 is shape figure of the present utility model.
Structure of the present utility model 2 description with reference to the accompanying drawings is divided into 5 parts, control transformer is made up of iron core 1, coil 3, input wires terminal 4 and output wiring terminal 5, iron core 1 inserts coil 3 and constitutes transformer, the transformer tap lead is welded on the input wires terminal 4, its lead-in wire of each independent winding of secondary coil is welded on respectively on the output wiring terminal 5, voltage-stabilizing controller 3 is by integrated-optic device, the pin of relay etc. is welded on the double-clad board, is installed in the flame-proof ABS system of moulding then and forms in the enclosure.When interconnecting associated end with lead after, above-mentioned control transformer and voltage-stabilizing controller just become the utility model.
Effect of the present utility model and effect are (see figure 1)s, when the elementary input of the B1 in the control transformer (2)～380V power supply, its secondary 11V power supply is through V1-4, C1, W, C2 rectification, after filtering, voltage stabilizing become 5V, offer gate circuit 01-09 and make the work power supply.～27V power supply offers integrated drive MC behind V5-8, C3, R9 rectifying and wave-filtering and relay J 1-3 makes the work power supply.Again through V9-12, the R6 rectification and voltage division offers divider resistance R1-5 as the sample of signal voltage of gate circuit 01-09 and form voltage detecting circuit to elementary～380V power supply after the bleeder circuit dividing potential drop that R7-8 forms.When the elementary input of B1～380V power source change, by R1-5, and the voltage detecting circuit that 01-09 forms will obtain voltage variety, output terminal a, the b of gate circuit 01-09, c three name a person for a particular job and present different high-low levels according to different voltage varieties, the tap of going to drive integrated drive MC drive relay J 1 or J2 or J3 switching B1 primary coil reaches the purpose of stable output secondary voltage to change the no-load voltage ratio relation of primary and secondary coil.
