Abstract

The invention discloses an electrical protection device, which comprises an insulating shell, a fuse tube, a resistor, an electromagnetic coil and a mechanical connecting rod. The insulating shell isprovided with a first wiring terminal, a lead-in terminal and a lead-out terminal. After the resistor and the electromagnetic coil are connected in series, a first end is electrically connected to thefirst wiring terminal, and a second end is electrically connected to the lead-out terminal. The electromagnetic coil is provided therein with a metal rod connected to the mechanical connecting rod. The mechanical connecting rod is connected to the fuse tube and is used for driving the fuse tube to rotate. The first end of the fuse tube can be electrically connected to the lead-in terminal the first wiring terminal, and the second end of the fuse tube can be electrically connected to the lead-out terminal. When the fuse tube is fused due to overcurrent or overvoltage, the current flows throughthe electromagnetic coil and causes the electromagnetic coil to generate a high-intensity magnetic field. The high-intensity magnetic field drives the mechanical connecting rod through a metal rod, thereby disconnecting the fuse tube from the first wiring terminal and the lead-in terminal, realizing the automatic trip-out after the fuse tube is fused, and improving an electrical protection effect.

Description

technical field [0001] The invention relates to the technical field of electrical protection, in particular to an electrical protection device. Background technique [0002] In the power system, in order to improve the safety of electricity use, it is generally necessary to install electrical protection devices. At present, miniature circuit breakers are usually used as electrical protection devices in the low-voltage section of power systems. However, the overcurrent protection current value of miniature circuit breakers is generally greater than 10A. For power systems with operating currents less than 10A, miniature circuit breakers cannot achieve overcurrent protection. Features. In order to realize overcurrent protection with working current less than 10A, some power systems use fuses as electrical protection devices. However, fuses do not have the second-stage protection function of circuit breakers, nor can they achieve good electrical protection effects. Contents o...
