Monitoring system for line protective cabinet

Abstract

The invention discloses a monitoring system for a line protective cabinet. The system comprises a general monitoring unit module, a signal transfer, alarm and display module and a storing and printingmodule. The general monitoring unit module is composed of a voltage and current detection module, a current sensor, a voltage sensor, a frequency tester, a current wavelength detector, an infrared camera, an infrared thermal imaging instrument, a temperature and humidity sensor, an electric quantity recorder, a GPS positioning module and a door magnetism detection module. The signal transfer, alarm and display module is composed of a first signal processing module, a computing chip, an alarm predicting module, a remote wireless alarm module, a liquid crystal signal display, an alarm indicating lamp and an alarming loudspeaker. The storing and printing module is composed of a second signal processing module, a storage chip and a printing module. The monitoring system has the advantages ofsimple structure and high practicality.

Description

technical field [0001] The invention relates to the field of line protection equipment monitoring, in particular to a monitoring system for line protection cabinets. Background technique [0002] The line protection cabinet is a kind of secondary equipment used to monitor and protect the safety of the operating circuit. The existing line protection cabinet mainly monitors and protects the current and voltage in the circuit and ignores the occurrence of its own problems, so it cannot be activated in time. It has the function of monitoring and alarming; when the existing line protection cabinet is running, it is impossible to send people to monitor it all the time, which not only increases the labor burden, but also the manual monitoring is inaccurate; the temperature and humidity of the environment where the line protection cabinet is located Its operation also has a great impact, so now a monitoring system for line protection cabinets is needed, which can not only perform re...

The existing line protection cabinet mainly monitors and protects the current and voltage in the circuit and ignores the occurrence of its own problems, so it cannot be activated in time. It has the function of monitoring and alarming; when the existing line protection cabinet is running, it is impossible to send people to monitor it all the time, which not only increases the labor burden, but also the manual monitoring is inaccurate; the temperature and humidity of the environment where the line protection cabinet is located Its operation also has a great impact, so now a monitoring system for line protection cabinets is needed, which can not only perform remote monitoring, reduce the labor burden, but also have more accurate monitoring effects, timely alarms, equipped with unique display and storage The printing module adds functions to the traditional monitoring system, so that people can intuitively understand the specific information in the monitored line protection cabinet, leaving cumbersome steps such as statistics and calculations, which is more convenient
