Low-voltage cable branch box working condition online adjustment alarm system

Abstract

A low-voltage cable branch box working condition online adjustment alarm system comprises a working condition information collection module, a temperature / humidity adjustment system, a working condition indicator, a front-end controller, a background server and alarm management application software. When it is detected that the temperature / humidity index in the box exceeds the early warning line and the detection data still exceeds the limit after continuous waiting for a period of time, a temperature / humidity adjusting system is started to adjust the temperature / humidity in the box, so that the branch box operates in the technical parameters; the self-temperature / humidity adjusting system is started; over time, the temperature / humidity information collection unit and the front-end controller carry out detection and working condition judgment on the temperature / humidity in the box again; if the mobile phone APP module is still in the early warning state, the front-end controller actively sends corresponding alarm signals to an administrator and a safety inspector, prompt is repeatedly carried out at certain time intervals in the mobile phone APP module, and alarm is stopped until the mobile phone APP module is queried manually. According to the invention, the uncertainty and blindness of the maintenance plan can be effectively avoided, and the work intensity of an administratoris reduced.

Description

technical field [0001] The invention relates to the technical field of low-voltage cable branch box monitoring, in particular to an on-line adjustment and alarm system for working conditions of a low-voltage cable branch box. Background technique [0002] With the deepening of distribution network transformation, more and more overhead low-voltage lines have been transformed into buried cables. Therefore, the low-voltage cable branch box is widely installed outdoors in the distribution line, and it is a common branch box without any control switch or detection equipment. The incoming and outgoing lines of this type of branch box are physically connected together and have the same electrical potential, and are used for branching or branching wiring. Because the taps in the box are subject to unfavorable factors such as on-site manufacturing process and operating environment, the proportion of cable accidents caused by taps is as high as 90%. [0003] The monitoring of low-v...

Problems solved by technology

The ambient air temperature will have a great impact on the performance parameters of the branch box, sometimes resulting in excessive humidity in the box, resulting in condensation and serious corrosion of the wiring terminals; or due to overload and other factors, the temperature in the box is too high, and the heat in the sealed It is difficult to discharge in a timely manner in the box, and this state usually leaves many unfavorable hidden dangers such as a decrease in the insulation strength of the box
