Abstract

The invention discloses a device for emergency protection of a circuit. The device comprises a substrate, a substrate is provided with a working cavity, first fixing blocks which are symmetrical leftand right are fixedly mounted on the bottom wall of the working cavity, a circuit groove is formed in the first fixing block, a conductive plate is fixedly mounted in the circuit groove, a wire connecting hole is formed in the conductive plate, a second fixing block is fixedly mounted above the first fixing block, a third fixing block is fixedly mounted at the upper right part of the second fixingblock, connecting blocks which are symmetrical front and back are fixedly mounted at the upper left part of the second fixed block, a conducting rod is rotationally mounted between the connecting blocks through a first connecting rod, a rolling groove is arranged in the conducting rod, and a rolling block is slidingly installed in the rolling groove. The device is provided with an automatic circuit cut-off mechanism according to the common emergency situations in a circuit so as to improve the practicability of the device, the device can be repeatedly used, fuse elements can be better replaced, the steps of replacing fuses are reduced, and the cost is saved.

Description

technical field [0001] The invention relates to the technical field of electrical emergency protection devices, in particular to a device for circuit emergency protection. Background technique [0002] In the circuit system, the most prone faults are short circuit, overload, grounding and lightning strike, etc. In order to ensure the safe and reliable operation of the power supply system, protection devices must be installed to monitor the working conditions of the power supply system, find faults in time and cut off the power supply of faulty equipment to prevent accidents from expanding. Due to the existence of parasitic inductance in the circuit, sudden changes in current caused by various reasons will generate voltage spikes, resulting in overvoltage. Contents of the invention [0003] In view of the deficiencies of the above-mentioned technologies, the present invention proposes a device for circuit emergency protection, which can overcome the above-mentioned deficie...
