Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
Referring to fig. 1, embodiment 1: in the embodiment of the utility model, a multichannel overcurrent and short circuit self-recovery safety device for an electric new energy automobile comprises a resistor R2, a self-recovery fuse R1, a diode D1, a power box, a switch T1 and a buzzer B1, the positive pole of the power box is connected with a switch K1, the other end of the switch K1 is connected with a self-recovery fuse R1, a resistor R2, a resistor R3, a self-recovery fuse R4, a resistor R5, a self-recovery fuse R6 and a buzzer B1, the other end of the resistor R2 is connected with the anode of a diode D1, the cathode of a diode D1 is connected with the cathode of a diode D2, the other end of a self-recovery fuse R1 and a first path of electric equipment, the other end of the resistor R3 is connected with the anode of a diode D5, the cathode of a diode D5 is connected with the cathode of a diode D5, the other end of a self-recovery fuse R5 and a second path of the diode D36, the cathode of the diode D6 is connected to the cathode of the diode D4, the other end of the self-healing fuse R6, and the third electrical device.
Because the electronic element PTC, namely the self-recovery fuse, is adopted to replace the conventional fuse, the PTC current data error is small, and the performance is stable.
The short circuit and overcurrent disconnection speed is ultra fast, 1-50 milliseconds can be quickly disconnected when the circuit is in short circuit and overcurrent, so that the circuit and the electric equipment are protected, the circuit is prevented from being on fire, the buzzer can give out an alarm sound to prompt short circuit after the fuse is disconnected, and then the circuit is known to be in short circuit by looking over the multi-way indicator lamps, so that hidden danger is prevented in timely maintenance. Because the self-recovery insurance is adopted, after the short-circuit fault is repaired, the short-circuit fault is not required to be replaced, and the energy-saving and convenient effects are achieved. In the figure, R1-is a self-recovery fuse PTCR2 is a current-limiting voltage-limiting resistor D1 of a light-emitting diode indicator lamp D2, D3 and D4 are alarm buzzers and multi-path fuse connected one-way diodes.
When the electric appliance works normally, because R1 is that the direct conductor is conductive, the indicator light and the buzzer both ends are zero voltage and can not be lighted and sound, when the electric appliance and the circuit are in short circuit or the current is too large to exceed the safety range of the calibrated value, R1 is quickly disconnected, the two ends of the light-emitting diode and the buzzer have positive and negative voltages, the indicator light can be lighted, and the buzzer sends out the alarm sound
