Abstract

The invention relates to an electrical fireproof current-limiting type protector, which comprises a main circuit, a plurality of load branches, an alternating current power supply, a slide rheostat and a central control unit, and is characterized in that the alternating current power supply is connected with the main circuit in series, the main circuit is respectively connected with the pluralityof load branches, and the plurality of load branches are connected in parallel; the alternating current power supply supplies power to the load branches, the slide rheostat is connected with the alternating current power supply in parallel and used for changing the output voltage of the alternating current power supply, and when a short-circuit fault occurs, the electrical fireproof current-limiting type protector can achieve rapid current-limiting protection at the microsecond-level speed, and the voltage is adjusted by adjusting the sliding resistor, and then the current is adjusted, so thatthe working current is limited within the range of multiple times of the rated working current, the hidden danger of electrical fire is effectively prevented and reduced, and the safety of the load is ensured.

Description

technical field [0001] The invention relates to the field of circuit protection, in particular to an electrical fire-proof current-limiting protector. Background technique [0002] With the increasing demand for electricity and the increasing number of electrical equipment, in the process of using electricity, in order to prevent electric shock and fire accidents caused by the defects of the electrical equipment itself or improper use, a current limiting protector must be installed in the circuit, which is effective To prevent the heat generated by the overcurrent phenomenon in the circuit and even the electrical fire. [0003] The current limiter is a device used to limit the current in the circuit, which can limit the fault short-circuit current and improve the stability of the power grid. An ideal current limiter has no effect on the normal operation of the grid, but can limit the short-circuit current close to the rated current value under fault conditions. The commonl...
