Online energy-taking monitor of drop-out fuse

Abstract

The invention relates to an online energy-taking monitor of a drop-out fuse. The online power-taking monitor comprises a main engine and an auxiliary engine which are both mounted on a tested circuit; the main engine and the auxiliary engine take electric energy from the tested circuit from respective online high-voltage energy-taking power supply modules; in power failure, supplying of a working power supply for other electrical elements in the machine is performed in a delayed manner; the auxiliary engine and the main engine are in wireless data transmission; the main engine and an upper computer are in wireless communication; in the main engine, the input end of a single chip microcomputer is connected with a first fuse position detection module and a wireless receiving module; the single chip microcomputer is in bidirectional transmission connection with the first online high-voltage energy-taking power supply module; and the output end of the single chip microcomputer is in wireless communication with the upper computer through a GSM module. By taking a supercapacitor as a back-up power supply, the service time of the monitor can be prolonged for 15-20 years; the problems existing in energy-taking of the online monitoring system are solved; and information of short circuit, overload and the like of branches and main lines and transformers of a power distribution line can be obtained in time, so that great convenience is brought to fault searching of maintenance and inspection staffs.

Description

technical field [0001] The invention relates to a monitoring technology of a fuse, in particular to an online energy-taking monitor for a drop-out fuse. Background technique [0002] The existing 10kV drop-out fuse online monitoring system takes power through the lithium battery inside the online monitoring module. When the 10kV drop-out fuse falls and loses power, the online monitoring communication module detects the blown fuse through gravity and horizontal induction, and triggers the MCU single-chip microcomputer. The MCU single-chip microcomputer sends the status of the fuse to the mobile phone of the maintenance personnel through the communication GSM module. [0003] Lithium batteries have a theoretical lifespan of 10 years. Lithium batteries used in the 10kV dropout fuse online monitoring system can only be fully charged once before installation, and cannot be recharged online afterwards; while the online monitoring module continues to work in harsh outdoor environme...
