Intelligent combiner box detector

Abstract

An intelligent combiner box detector disclosed by the present invention comprises a master control box, a master control CPU is assembled in the master control box, a support is fixedly installed at the top of the master control box, a guide rail seat is arranged at the top of the support, four current transformers are assembled on the guide rail seat, a measuring groove is formed in each current transformer, rotating rods are sleeved in the four current transformers, and a clamping sleeve matched with the specification of the current transformer is sleeved in each current transformer; according to the intelligent combiner box detector, through arrangement of each component on the current transformers, the states of the plurality of current transformers can be regulated and controlled by rotating the rotating rod, so that the plurality of current transformers can be turned on at the same time, and the effect of conveniently measuring a plurality of electric wires is achieved; and the problem that an existing device is poor in current measurement efficiency is solved. In addition, through the arrangement of the guide rail seat, current and voltage in multiple branches can be measured synchronously and efficiently.

Description

technical field [0001] The invention relates to the technical field of circuit detection, in particular to an intelligent combiner box detector. Background technique [0002] For photovoltaic power plants that have been in operation for more than 3 years, some combiner boxes have communication failures, and the maintenance time is long and the cost is high. The background monitoring system of the station cannot receive the detection data of the combiner boxes in real time. When the solar panel or insurance is damaged, the monitoring background cannot give an alarm in time. If the amount of damage is too large, it will affect the power generation of the whole field. Since the combiner box brings together multiple solar panel arrays, the positive and negative poles of all the arrays are connected to the positive busbar and the negative busbar respectively. [0003] In response to the above problems, this project designs a portable device for quickly detecting photovoltaic ar...
