Abstract
The utility model discloses an electrical shock controller for experimental electrical equipment. The electrical shock controller is serially connected between experimental equipment and a power supply access end. The device can detect whether a circuit of the experimental electrical equipment is overloaded through a negative resistance light emitting diode, and control and regulate the connection and the disconnection of a relay and control the switching-on and switching-off statuses of a triode, so as to protect the experimental electrical equipment. The electrical shock controller is simple in structure, reliable to operate, comprehensive to protect, convenient to regulate, sensitive to respond and long in service life, and integrates functions of overload protection, short circuit protection and other protection together.
Description
Technical field
The utility model relates to a kind of experiment electric equipment electric shock controller.
Background technology
The electric shock controller of the experiment electric equipment of using on the market is very limited to the protective capability of experiment electric equipment now; can not effectively protect the experiment electric equipment during high pressure overload; and when doing experiment through regular meeting the situation that high pressure transships appears; this just makes the electric shock controller of current experiments electric equipment can not play the protective effect to circuit, so a effective electric shock controller of needs is protected the experiment electric equipment in the operating circuit.
Summary of the invention
The purpose of this utility model is that protection experiment electric equipment avoids being damaged because of situations such as short circuit, overloads.
Concrete technical scheme of the present utility model is as follows: a kind of experiment electric equipment electric shock controller, be connected between experimental facilities and the power access end, described electric shock controller comprises normally closed interlock J1-1, reset button AN, capacitor C 1, load R1, load R2 and the diode VD2 and the relay J of negative resistance light-emitting diode VD1, triode VT, relay J;
The input of described reset button AN is connected with the positive source incoming end, and the output of described reset button AN is connected with an end and the negative pole of described diode VD2, the end of described normally closed interlock J1-1 of an end of described capacitor C 1, the positive pole of described negative resistance light-emitting diode VD1, described relay J;
The other end of described capacitor C 1 is connected with the end of the negative pole of described negative resistance light-emitting diode VD1, described load R1, the end of described load R2;
The other end of described load R1 is connected with an end of power cathode incoming end, described experimental facilities; The other end of described load R2 links to each other with the base stage of described triode VT; The collector electrode of described triode VT links to each other with the positive pole of described diode VD2, the other end of described relay J, and the emitter of described triode VT is connected with the other end of described experimental facilities, described load R1, described power cathode incoming end; The other end of normally closed interlock J1-1 is connected with the other end of described experimental facilities.
Described capacitor C 1 is anti-electromagnetic interference, chooses in the 0.01-0.1uF scope.
Technique effect: the utility model just is being based on provides a kind of electric equipment that electric equipment damages that prevents to test to experiment electric equipment overload situations; the very big electric current that it produces by testing circuit overload back; the conducting of control negative resistance light-emitting diode VD1 and by; then trigger relay J action; cut-out is to the power supply of experiment electric equipment, thereby plays the purpose of protection.
Simultaneously, return to the critical value of voltage when following at external voltage, click reset button AN, negative resistance light-emitting diode VDl is ended, triode VT ends, and relay J discharges, and recovers to power to the load.
Advantage of the present utility model is: the utility model is simple in structure, easy for installation, can be used for any experiment electric equipment, protects for different electrical equipment.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
In conjunction with Fig. 1 the utility model is described: when external voltage did not surpass the critical value of the voltage of setting, negative resistance light-emitting diode VD1 ended, and triode VT also ends because of no base current, not adhesive of relay J, its normally closed interlock J1-1 closure, powering load.When in a single day external voltage surpasses the critical value of setting voltage; negative resistance light-emitting diode VD1 is conducting by ending; the luminous expression electric voltage over press of negative resistance light-emitting diode VD1; its electric current that flows through negative resistance light-emitting diode VD1 provides triode VT base current; triode VT conducting, the relay J adhesive, normally closed interlock J1-1 disconnects; cut off the power supply of load, play a protective role.Return to the critical value of voltage when following at external voltage, click reset button AN, negative resistance light-emitting diode VDl is ended, triode VT ends, and relay J discharges, and recovers to power to the load; The capacitor C 1 in parallel with negative resistance light-emitting diode VD1 is anti-electromagnetic interference, can choose in the 0.01-0.1uF scope.
Wherein reset button AN and negative resistance light-emitting diode VD1, triode VT-9013, normally closed interlock J1-1, capacitor C 1(0.1 μ F), load R1(1k Ω), load R2(10k Ω) and diode VD2-1N4148 and relay J be in series, capacitor C 1 is in parallel with negative resistance light-emitting diode VD1, diode VD2-1N4148 and relay J are in parallel, load R1(1k Ω), load R2(10k Ω) and triode VT-9013 be in parallel, capacitor C 1, negative resistance light-emitting diode VD1 and load R1(1k Ω) be in series, diode VD2-1N4148 and relay J and triode VT-9013 are in series.
