Application method of direct current (DC) monitoring device

Abstract

The invention discloses an application method of a direct current (DC) monitoring device, which is realized by the following steps: (1) switching over all DC loads to a temporary switch-over screen, putting all loads of a station on a temporary charging device and a temporary accumulator cell group, wherein, in an original DC screen, except that a connecting terminal is electrified, other devicesare all out of running; (2) dismantling original monitoring equipment, an original insulated locator and an original insulation current mutual conductor on a feeder circuit, and dismantling all connecting wires among screens and the connecting wires of a control loop; (3) installing a new monitoring equipment, a new insulated locator and connecting wires of the two; (4) replacing a main fuse of accumulator cells into a DC air circuit breaker; replacing a main switch and section switches controlled by the main switch to enable the main switch and the section switches to meet range requirement; (5) testing and debugging all functions of the DC monitoring device ; and (6) uploading DC information, and accessing a background computer and telecontrol equipment. The invention has the advantages that: (1) the monitoring device has an independent circuit board which can be plugged in and out electrically, thereby being more convenient to overhaul; (2) the monitoring device has high accuracy, can alarm accurately and can control the even and float charging procedure of accumulator cells more accurately.

Description

Technical field: [0001] The invention belongs to the field of current monitoring and relates to the application of a direct current monitoring device. Background technique: [0002] The existing GZDK-IV monitoring machine and GZDJ-IV insulation locator have a large number of serious defects such as frequent black screens, crashes, false alarms, and data drift, and are controlled by analog ports. And because there are a lot of defects in the DC equipment, there are many stations that need to be transformed, and the transformation cost is very tight. There is no way to replace the whole screen. If you want to transform the DC monitoring device without replacing the module, many manufacturers do not have the corresponding Technical strength. Invention content: [0003] The purpose of the present invention is to overcome the shortcoming of above-mentioned prior art, provide a kind of DC monitoring device application method, according to the following steps: [0004] (1) Tran...
