Abstract
The utility model provides an AC voltage stabilizing device for the public, being used in the circuits of various mechanical equipment to stabilize the voltage of a control circuit, a lighting circuit and a signal circuit. The utility model is synthesized by a control transformer whose primary coil is provided with a tap and a voltage stabilizing controller composed of an integrated electronic device and thyristor. The primary and the secondary coils are independent, when the input voltage of an electric network ranges from 270V to 440V, under the control of voltage stabilizing device, the secondary output voltage can control the output, and the signal voltage is stabilized within the range required by the industrial electrical equipment, such as a numerical control device, an instrument, etc. The utility model has the advantages of less circuit elements, good stability and compact structure.
Description
The utility model belongs to industrial electrical equipment, and specifically a kind of conversion plant equipment exchanges the device of control in the secondary circuit, illumination, signal voltage.
The existing domestic various control transformers that use in plant equipment all do not have voltage stabilizing function.(seeing 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 industrial electrical equipments (as A.C. contactor, auxiliary reclay, numerical control device etc.).The family expenses ac automatic voltage regulator is because the primary and secondary coil of transformer is same winding in addition, on high-tension side voltage failure directly influences low-pressure side, and the voltage usable range, the precision of voltage regulation, aspects such as voltage responsive time are former thereby can not use on plant equipment.
The purpose of this utility model is to provide a kind of stable control, illumination, AC stabilizer of signal voltage done to the public in various plant equipment control circuits.
Technical solution of the present utility model is: be used for the voltage stabilizing control transformer accompanying drawing 2 that the conversion plant equipment exchanges control, illumination, signal voltage, a voltage-stabilizing controller (1) is arranged, also have a control transformer (2).When voltage-stabilizing controller (1) just becomes the utility model with control transformer (2) after lead is connected both sides' associated end, the elementary winding that it is characterized in that control transformer (2) has a plurality of taps, described tap all is connected each controllable silicon one end of voltage-stabilizing controller (1), and the voltage sample circuit in the voltage-stabilizing controller (1) is by diode V

Input voltage of the present utility model is 110V to 660V, and output voltage is 6.3 to 250V under zero load or load, and the precision of voltage regulation is ± 3% to ± 10%, and voltage rings the shadow time less than below the 10ms.
Output capacity of the present utility model is 40 to 2500VA.
Advantage of the present utility model and good effect are:
1, when primary voltage changes in-68% to+115% scope, its secondary output voltage all can be stabilized in ± 3% to ± 10% in, make various instrument working stabilities, show correct.
2, use the utility model after, industrial electrical equipments such as A.C. contactor, auxiliary reclay are because mains fluctuations exceed its usable range (especially in shortage of electric power area and summer harvesting and sowing and drought resisting season) makes the decline of contactor electromagnet suction be directed at the contact to burn the phenomenon that causes burn-down of electric motor and eliminated.Make numerical control device owing to the shutdown phenomenon that the voltage fluctuation reason causes is eliminated.
3, used the utility model after, domestic many shortages of electric power area, particularly vast township and village enterprises and individual enterprise often can't work owing to the cause of fluctuation of voltage is directed at A.C. contactor, auxiliary reclay, and the electrical equipment of the design of the national standard on the former plant equipment removed and directly use the phenomenon of knife switch will remove the end and eliminate.This electrical equipment that will guarantee standard design has kept short-circuit protection, overload protection, o-volt protection, function such as earth leakage protection and safeguarded operator's personal safety.
4, application prospect is extensive.Its electrical design of machine tool manufacturing firm of existing domestic 95 percent all must peace Machine Tools Electric Device-General technical conditions GB5226-85 standard in 611 regulation designs, promptly for lathe with 5 above solenoids, must adopt the transformer that separates winding to give control and signal circuit power supply.Again in 911 regulations of the People's Republic of China's Electrical equipment of industrial machines general technical specifications that is about to use (exposure draft substitutes Machine Tools Electric equipment GB5226-85 standard), control circuit application of power transformer-supplied.Transformer must be an independent winding.In addition control transformer is rudimentary easily-consumed products, and just no longer repair bad back, and produce 2,500,000 of various control transformers existing domestic every year approximately, and its requirement increases progressively with the amplitude of annual 8%-15%, so the utility model use prospect is widely.
The utility model further specifies in conjunction with concrete structure.
