The attached drawings indicate the following:
10. battery 20 and rectifier module
30. A control module 40 and an indication module.
Detailed Description
Referring to fig. 1 and 2, a specific structure of a preferred embodiment of the present invention is shown, including a discharge tube TVS, a resistor R1, a capacitor C, a transformer T, a battery 10, a rectifier module 20, a control module 30, and an indication module 40.
One end of the discharge tube TVS and one end of the resistor R1 are both connected with a high-voltage signal; one end of the capacitor C is connected with the other end of the resistor R1, and the other end of the capacitor C is grounded; one end of the primary winding of the transformer T is connected to the other end of the discharge tube TVS, and the other end of the primary winding of the transformer T is grounded.
The first end of the rectifying module 20 is connected to one end of the secondary winding of the transformer T, the second end of the rectifying module 20 is connected to the other end of the secondary winding of the transformer T, and the third end of the rectifying module 20 is connected to the negative electrode of the battery 10. As shown in fig. 2, the rectifier module 20 is a rectifier.
The output end of the control module 30 is connected to the negative electrode of the battery 10 and the fourth end of the rectifying module 20; one end of the indication module 40 is connected to the input end of the control module 30, and the other end of the indication module 40 is connected to the positive electrode of the battery 10. As shown in fig. 2, the control module 30 is a one-way thyristor. The indication module 40 includes an LED41 and/or a buzzer 42, and in this embodiment, when the indication module 40 is composed of an LED41 and a buzzer 42, the LED41 and the buzzer 42 are connected in parallel. And a switch S is connected in series between the indication module 40 and the positive electrode of the battery 10.
Detailed description the working principle of the present embodiment is as follows:
the switch S is always closed whether or not a high voltage signal enters the circuit.
When no high-voltage signal enters the circuit, the discharge tube TVS is in an off state, and the current passes through the resistor R1 and the capacitor C and then is grounded through the iron shell of the RJ45 connector, at this time, although the switch S is closed, the control module 30 (i.e., the one-way thyristor) is in an off state, so that the indication module 40 is in an unresponsive state, that is, the LED41 is not lit and/or the buzzer 42 is not sounded.
When a high-voltage signal enters the circuit, the discharge tube TVS is started, and current flows through the discharge tube TVS and the primary winding of the transformer T and then is discharged through the iron shell of the RJ45 connector in a grounding mode, so that high voltage is intercepted; meanwhile, after the discharge tube TVS is started up by high voltage, the transformer T steps down and shunts, the voltage after step-down is converted into direct current voltage by the rectifier module 20 (i.e., a rectifier), the control module 30 (i.e., a one-way thyristor) is turned on at the moment, and the indication module 40 responds, i.e., the LED41 lights up and/or the buzzer 42 sounds.
When the control module 30 (i.e., the triac) is turned on, even if the high voltage signal entering the circuit has been discharged to ground, the indication module 40 is still in a responsive state, i.e., the LED41 can still be lit and/or the buzzer 42 can still sound; if the indication module 40 is to stop responding, i.e. the LED41 is turned off and/or the buzzer 42 stops sounding, the switch S is turned off; meanwhile, in order to ensure that the user is reminded next time, after the switch S is turned off, the switch S needs to be turned on again.
The utility model discloses a design focus lies in:
by arranging the discharge tube, the resistor and the capacitor in the circuit, when high-voltage current enters the circuit, the high-voltage current can be intercepted, and circuit equipment is protected; through setting up the instruction module in the circuit, when high-voltage current got into the circuit, the instruction module response reminded the operating condition of user's present equipment, made the user can in time make the action of protection equipment to reduce the risk that equipment received the harm.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the technical scope of the present invention, so that any slight modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments are all within the scope of the technical solution of the present invention.
