Abstract

The invention relates to an electrical fire-proof current-limiting protector, which comprises a main circuit, a plurality of load branches, an AC power supply, a sliding rheostat and a central control unit, the AC power supply and the main circuit connected in series, the main circuit is connected to a plurality of load branches respectively, the plurality of load branches are connected in parallel, the AC power supplies power for a plurality of load branches, and the sliding rheostat is connected in parallel to the AC power , to change the output voltage of the AC power supply. When a short-circuit fault occurs, the electric fire-proof current-limiting protector of the present invention can realize fast current-limiting protection at a speed of microseconds, adjust the voltage by adjusting the sliding resistor, and then adjust Current, so that the working current is limited within the range of several times of the rated working current, so as to effectively prevent and reduce the hidden danger of electrical fire and ensure the safety of the load.

Description

Technical field [0001] The present invention relates to the field of circuit protection, and more particularly to an electrical fire limit stream protector. Background technique [0002] With the increasing demand of electricity, the increasing electrical equipment is increasing, in the electrical equipment, in order to prevent the electrical equipment itself or the body's electric shock and fire accident caused by improper use, the current limit protector must be installed in the circuit. Prevent heat generation and even electrical fire generation of overcurrent phenomena in the circuit. [0003] A current limiter is a device for limiting the current size in the circuit, which enables limits to the fault short circuit current to improve the stability of the grid. The ideal limiting limiter has no effect on the normal operation of the grid, and the short-circuit current can be limited to the rated current value in the fault. The commonly used limiting limiter is a superfluidizer....
