The utility model which has the advantages of small size, light weight, convenient installation and low cost can stably provide the voltage, current given value required for the loads, and the voltage and the current are inphase with the mains supply.
Description
The utility model is a kind of homophase vector voltage current regulator that is used to provide the electric current and voltage set-point on electrician's type instrument verification device.
At present, the voltage and current regulator that is adopted in electrician's type instrument verification device is all decided with JJG124-82 ammeter, voltmeter and wattmeter vertification regulation, and each adjuster is made up of a self-coupling type inductive type fine tuning voltage regulator, self-coupling type inductive type coarse adjustment voltage regulator and a fine tuning transformer, (stream) device that boosts.This adjuster exists the labile weak point of electric current and voltage phase place that volume is big, inconvenience, output are installed.
Task of the present utility model is, substitute self-coupling type inductive type fine tuning voltage regulator in the existing voltage and current regulator with a fine tuning potentiometer and compensation condenser, provide a kind of volume little, in light weight, can stably export the homophase vector voltage current regulator with mains supply in-phase voltage electric current.
The utility model homophase vector voltage current regulator is made up of fine tuning voltage regulator and coarse adjustment voltage regulator, fine tuning transformer, (stream) device that boosts.It is characterized in that described fine tuning voltage regulator is made of fine tuning potentiometer and compensation condenser.The fine tuning potentiometer is connected between the input and output of this fine tuning voltage regulator, and compensation condenser is connected in parallel between two outputs of this fine tuning voltage regulator.Another input of this fine tuning voltage regulator communicates with another outlet internal.Two outputs of this fine tuning voltage regulator join with two inputs of above-mentioned fine tuning transformer respectively; Two outputs of fine tuning transformer, an input of one of them output and above-mentioned boosting (stream) device joins, an output of another output and above-mentioned coarse adjustment voltage regulator joins, and another input of another output of coarse adjustment voltage regulator and (stream) device that boosts joins; Two of (stream) device output terminations of boosting load; Slightly, fine tuning voltage regulator two inputs separately join with mains supply separately.
The advantage of the utility model homophase vector voltage current regulator is: 1. owing to adopted with fine tuning potentiometer and the alternative self-coupling type inductive type fine tuning voltage regulator of the prior art of compensation condenser, so obviously reduced the volume and weight of whole voltage and current regulator, also reduced cost.2. under the 50HZ alternating-current power supply, because the effect of compensation condenser, make the mains supply homophase of output and the input of fine tuning transformer, the while also can make whole voltage and current regulator stably export required and the electric current and voltage set-point civil power homophase to load.
Accompanying drawing is the utility model homophase vector voltage current regulator internal circuit diagram.
Following adjoint is done further embodiment explanation:
The utility model homophase homophase vector voltage current regulator, by thin, coarse adjustment voltage regulator T1, T2, fine tuning transformer B1 boosts (stream) device B2 and thick, the fine tuning turn-knob 17,18 that are on this adjuster panel are formed.Wherein, Fine tuning voltage regulator T1 is made of fine tuning potentiometer R and compensation condenser C, and fine tuning potentiometer R is connected between its input 1 and the output 3.Compensation condenser C is connected in parallel between output 3 and 4.Input 2 and output 4 inner straight; Two outputs 3,4 of fine tuning voltage regulator T1 join with two inputs 5,6 of fine tuning transformer B1 respectively; Output 7 in two outputs 7,8 of fine tuning transformer B1 joins with the input 13 of (stream) device B2 that boosts, another output 8 joins with the output 11 of coarse adjustment voltage regulator T2, and another output 12 of coarse adjustment voltage regulator T2 joins with another input 14 of (stream) device B2 that boosts; Two outputs 15,16 and the load of (stream) device of boosting joined.Here two inputs 9,10 of two of fine tuning voltage regulator T1 inputs 1,2 and coarse adjustment voltage regulator T2 join with 220 volts of civil powers, 50HZ alternating current respectively, and the induction reactance that the capacitive reactance that the capacitance of compensation condenser C is produced by capacitor C under 50HZ alternating current situation equals to be produced on the fine tuning transformer B1 is calculated gained.Because both capacitive reactances equate with induction reactance, so voltage, electric current on the compensation condenser C and the phase difference that is produced on the fine tuning transformer B1 obtain complementation, both parallel impedances are resistive, make fine tuning transformer B1 and the voltage of (stream) device output of boosting, electric current all the time with the mains supply homophase.The coarse adjustment turn-knob of regulating during use on this adjuster panel 17 can make mains supply be divided to by no-load voltage ratio on the input 13,14 of (stream) device B2 that boosts through self-coupling type inductive type coarse adjustment voltage regulator T2.The fine tuning pressure regulation turn-knob 18 that adjusting is on this adjuster panel can make mains supply be divided to the input 5 of compensation condenser C and fine tuning transformer B1 through fine tuning potentiometer R, on 6, and the vector of acquisition and mains supply homophase, after the output of fine tuning transformer B1 no-load voltage ratio, make (stream) device B2 input 13 that boosts again, voltage on 14 (electric current) boosts (stream) through output 15 through (stream) device B2 no-load voltage ratio of boosting again for voltage (electric current) stacking value of coarse adjustment voltage regulator T2 and fine tuning transformer B1 output, 16 to load output required with the voltage mains supply homophase, the electric current set-point.
