Abstract
The utility model discloses an avometer capable of surveying silicon controlled rectifier (SCR). A circuit composed of an electric bulb 1, a direct current power supply 3, a potentiometer 4, a resistor 5, and a three foot socket 2 is attached on the wiring point of a positive-negative electric pen in the existing avometer. The electric current grade of the avometer is utilized to directly survey the triggering current value of random SCR. The utility model has the advantages of convenient operation, and high precision. The avometer capable of surveying silicon controlled rectifier (SCR) solves existing frauds that dedicated devices are depended to judge the main performance of the SCR, or experience is depended for a long tine.
Description
The utility model relates to a kind of improvement of multifunctional testing instrument, is applicable to measure the silicon controlled special parameter.
For a long time, people judge the quality of thyristor or test it related parameter, mainly is to use all kinds of instrumentations.The versatility of these instruments is poor, and carries inconvenience.Existing universal electric meter can not accurately be measured the quality of thyristor triggering and conducting performance.Therefore, under many circumstances, people can only the dependence experience judge the quality of thyristor roughly.Prior art is referring in 1988 fourth phase of " radio " magazine 44 pages of " testing controllable silicon with multimeter " literary compositions.
The purpose of this utility model provides a kind of universal electric meter that can accurately measure the silicon controlled trigger current value.
The utility model is achieved in that on the positive and negative test pencil wiring point of existing universal electric meter inside and connects one by a three-pin socket, a bulb, a direct supply, a resistance and the circuit that potentiometer is formed.Utilize the electric current retaining of universal electric meter, observe that bulb is whether luminous judges that controllable silicon whether can conducting, read the numerical value of trigger current from the indication of universal electric meter.
The utility model has the advantages that by improvement, make it can directly measure silicon controlled trigger current value universal electric meter.Judge the performance of its triggering and conducting, the function of enhancing universal electric meter and easy to use.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is the front elevation that can measure the silicon controlled universal electric meter.
Fig. 2 is the circuit theory diagrams that can measure the silicon controlled universal electric meter.
See figures.1.and.2, on the basis of universal electric meter, set up one, be connected on the positive and negative test pencil wiring point of universal electric meter inside by 3, one potentiometers 4 of 1, one direct supply of 2, one bulbs of a three-pin socket and the circuit that resistance 5 is formed.During use, earlier universal electric meter is pushed the electric current gear, estimate and select range, again with three extremely corresponding insertions in three jacks 2 of tested controllable silicon 6, regulator potentiometer 4, whether bulb 1 is luminous judges that can controllable silicon 6 triggering and conducting by observing.If can conducting, write down bulb and begin universal electric meter indicated value when luminous, be the trigger current value.
Architectural feature of the present utility model is: fixing bulb 1 on the panel of universal electric meter, 4, one three-pin sockets 2 of potentiometer.Three wiring points of three-pin socket correspond respectively to three wiring points of K, A, G in the circuit theory diagrams.Load onto the battery folder of power supply 3 within it on the suitable position of portion.During wiring, the G wiring point of three-pin socket connects the negative test pencil wiring point of universal electric meter, and an end of resistance 5 is connected to the positive test pencil wiring point of universal electric meter, and the other end is received the upper end of potentiometer 4.The sliding end of potentiometer, the lower end of potentiometer, the anodal line of power supply 3, an end of bulb 1 couple together with lead.The other end of bulb 1 is connected to the A wiring point of three-pin socket 2, and the negative pole of power supply 3 is connected in the K wiring point of three-pin socket 2, and potentiometer 4 is connected into resistance value minimizing when turning clockwise.
Universal electric meter after the improvement does not influence existing test function.
Claims (2)
1, a kind of silicon controlled universal electric meter of measuring is characterized in that setting up three jacks on multimeter, a bulb, a direct supply, a resistance and a potentiometer.
2, universal electric meter according to claim 1 is characterized in that: said three jacks can be three-pin sockets; Said bulb can be the element that any one energy indicator current passes through.
