Problems solved by technology

[0002] At present, most of the 10kV power distribution protection devices follow the relay protection devices used in substations and switching stations. The workplaces of such devices are indoors, and most of them adopt rear plug-in structures and are equipped with fragile liquid crystal modules. Requirements for outdoor workplaces; especially in complex and harsh working environments such as salt spray, humid heat, high altitude and small spaces, traditional relay protection devices need to be improved in terms of reliability, convenience of operation and maintenance, and service life.

Abstract

The invention relates to a power distribution protection device. The power distribution protection device comprises a shell, and an alternating current plug-in, an outlet plug-in and a first processorare arranged in the shell in a stacked mode. The alternating current plug-in, the outlet plug-in and the first processor are respectively connected in an occlusion manner through a plug-in pipe and acontact pin; and the plug-in pipe is internally provided with a socket matched with the contact pin, one side of the outer part of the shell, which faces the alternating current plug-in, is providedwith a first connector and a second connector, the first connector is internally provided with a female head which penetrates the shell and is connected with the alternating current plug-in, and the second connector is internally provided with a network port which penetrates the shell and is connected with the alternating current plug-in. The power distribution protection device provided by the invention has the advantages of being convenient to operate, flexible to use and convenient to use in a narrow space and an outdoor environment.

Description

Technical field [0001] The present invention relates to the technical field of power systems, in particular to a power distribution protection device. Background technique [0002] At present, most of the 10kV power distribution protection devices follow the relay protection devices used in substations and switching stations. The working places of these devices are indoors. Most of them use rear plug-in structure and are equipped with vulnerable liquid crystal modules. It is generally difficult to meet the requirements of shielding and Requirements for outdoor workplaces; especially in complex and harsh working environments such as salt spray, damp heat, high altitude, and small spaces, traditional relay protection devices need to be improved and improved in terms of reliability, convenience of operation and maintenance, and service life. perfect. Summary of the invention [0003] The technical problem to be solved by the present invention is to provide a power distribution prote...
