Portable direct-current looped network searching and unlooping instrument

Abstract

The invention provides a portable direct-current looped network searching and unlooping instrument which comprises a box body structure, the box body structure comprises a box body and a box cover movably connected with the box body, wherein a signal collector, a branch detector and a system analyzer are arranged in the box body, the signal collector is connected with the branch detector through awire. The box body is divided into a plurality of placement areas by a partition structure, the signal collector, the branch detector and the system analyzer are all correspondingly arranged in one placement area, and the branch detector and the system analyzer are used for realizing detection of different branches. The signal collector, the branch detector and the system analyzer are arranged ina partitioned mode, so that an operator operates conveniently during work, all the devices are independent of one another, inconvenience in taking or mutual interference during use is avoided, the layout is reasonable, the occupied space is saved, and the instrument is convenient to take, store and release in time according to needs; and the bearing capacity of the box body structure is expanded.

Description

technical field [0001] The invention relates to the technical field of circuit maintenance equipment, in particular to a portable DC ring network search and release device. Background technique [0002] The current loop closure search indirectly reflects the information of the two DC loop closures through other abnormalities. If DC grounding occurs, both sets of DC systems will report a grounding signal, and a loop in the DC system can only be found in the process of pulling the circuit to find the DC grounding. The search process is usually by pulling the road, and the protective device of the running equipment needs to be disabled for a short time, which is dangerous and time-consuming. On-site staff generally rely on experience or power outage maintenance to de-loop the DC power system. When a ring network fault occurs, the substation does not have a special DC system ring network alarm device to issue an early warning and troubleshoot the ring network fault. There is n...

Problems solved by technology

[0003] The accommodating space of the ring solution instrument is usually limited, which cannot be well utilized. It is more cumbersome to use and it is easy to cause scattering problems during use, which causes a lot of inconvenience to the actual detection work of the operator, and the overall expansion performance of the device needs to be improved.
