Abstract
The invention provides an electric power protection and control device and relates to the technical field of electric power protection devices. The electric power protection and control device comprises a power supply system (1), an overload protector (2) and load electrical appliances (4). The electric power protection and control device is characterized in that the electric power protection and control device further comprises a safety detection device (3) and on-off detection devices (5). The power supply system (1) is connected with the overload protector (2) and the safety detection device (3). The safety detection device (3) is connected with a plurality of load electrical appliances (4), wherein an input end and an output end of each load electrical appliance (4) are respectively connected with one on-off detection device (5), and each on-off detection device (5) is connected with the safety detection device (3). According to the invention, the structure is simple, the on-off detection devices (5) are added, fault parts can be rapidly detected, maintenance personnel can rapidly rush to repair in place, the shutdown time of equipment is shortened, and the economic loss is reduced.
Description
Technical field
The present invention relates to electric protection device technical field, be specifically related to a kind of electric power protection control device.
background technology
After the development experience of relay protection of power system electromechanical type, rectification type, transistor-type and integrated circuit type several stage, develop into now the Microcomputer Protection stage.The development history microcomputer protective relay of microcomputer protective relay refers to the relaying protection formed based on digital computer (comprising microcomputer).It originated from for the 20 actual middle and later periods sixties, was in Australia of Britain and the U.S..After the development experience of relay protection of power system electromechanical type, rectification type, transistor-type and integrated circuit type several stage, develop into now the Microcomputer Protection stage.But existing automatic power protective device is expensive, is not also commonly used, so we have devised a kind of automanual electric protection device.
summary of the invention
The object of this invention is to provide a kind of electric power protection control device, its structure is simple, adds switching detection device, can promptly detection failure part, and maintenance personal can rapid nine tails repairings, have saved the time of equipment downtime, have reduced economic loss.
In order to solve the problem existing for background technology, the present invention is by the following technical solutions: it comprises electric power system 1, overload protective device 2, load electrical appliance 4, it is characterized in that it also comprises safety detection device 3, switching detection device 5, described electric power system 1 is connected to overload protective device 2, safety detection device 3, safety detection device 3 is connected with several load electrical appliance 4, it is characterized in that input and the output point of described each load electrical appliance 4 are connected to a switching detection device 5, each switching detection device 5 is all connected with safety detection device 3.
Operation principle of the present invention: when load electrical appliance breaks down, each switching detection device, by the break-make situation of low current switching detection device, flows to safety detection device for maintenance personal's reference failure judgement part, rushes to repair rapidly.
The present invention has following beneficial effect: its structure is simple, adds switching detection device, can promptly detection failure part, and maintenance personal can be just repairing rapidly afterwards, has saved the time of equipment downtime, has reduced economic loss.
accompanying drawing explanation
Fig. 1 is electrical schematic diagram of the present invention.
