Abstract

The invention relates to the technical field of the power protection device, especially to a power protection control device comprising a power supply system (1), an overload protection device (2), load electric appliances (4), a safety detection device (3), and on-off detection devices (5). The Safety detection device (3), on-off detection device (5) is connected with the overload protection device (2) and the safety detection device (3); and the safety detection device (3) is connected with a plurality of load electric appliances (4). The device is characterized in that an input terminal and an output point of each load electric appliance (4) are connected with the on-off detection devices (5); and each on-off detection device (5) is connected with the safety detection device (3). According to the invention, the power protection control device has a simple structure; and with the on-off detection devices (5), a fault part can be detected rapidly and the maintenance staff can carry out repairing rapidly at a fault location; and the equipment shutdown time is saved; and the economic losses are reduced.

Description

technical field [0001] The invention relates to the technical field of power protection devices, in particular to a power protection control device. Background technique [0002] The development of power system relay protection has gone through several stages of electromechanical type, rectification type, transistor type and integrated circuit type, and now it has developed into the stage of microcomputer protection. Microcomputer relay protection development history Microcomputer relay protection refers to relay protection based on digital computers (including microcomputers). It originated in the late 1960s in the United States, Australia and the United States. The development of power system relay protection has gone through several stages of electromechanical type, rectification type, transistor type and integrated circuit type, and now it has developed into the stage of microcomputer protection. However, the existing automatic power protection device is expensive and ...
