The utility model content
The purpose of this utility model is to provide a kind of Intelligent switch cabinet detection system at this, adopt at present popular transient state ground voltage (TEV) and ultrasound wave (AE) to detect the method for shelf depreciation, switch cubicle is realized to uninterrupted monitoring in 24 hours, thus the potential safety hazard of having avoided switch cubicle to cause due to electric discharge.
The utility model is achieved in that a kind of Intelligent switch cabinet detection system of structure, and it is characterized in that: this detection system comprises host computer, server, on-site detecting unit, collecting unit; Described host computer is connected with server; By the GPRS wireless communication, between described on-site detecting unit and collecting unit, by 485 buses, be connected communication between on-site detecting unit and server.
According to a kind of Intelligent switch cabinet detection system described in the utility model, it is characterized in that: described collecting unit comprises:
Sensor, for detection of switch cubicle ground electric wave signal;
Conditioning module; Amplification and filtering for signal;
Capture card; For data acquisition;
Mainboard; For data, process and transmission, and command;
Wherein sensor is connected with conditioning module by signal wire; Conditioning module is connected by signal wire with capture card; Between capture card and mainboard, by bus, be connected.
The utility model, according to effective theory and the experience of practice at home and abroad, has designed the switch cubicle on-line monitoring system detected based on the ground electric wave.Online acquisition unit (monitoring node) can provide permanent and semi-permanent switch cabinet of converting station on-line monitoring function.It is integrated ground radio wave sensor, the amplitude of ground electric wave signal and variation tendency respectively with switch cubicle in local discharge signal have deterministic interconnection, thereby can realize the partial discharge of switchgear state in work is monitored and analyzed.
Owing to adopting the non-intrusion type means of testing, monitoring system, without switch cubicle classification and design are proposed to special change, is a kind of extensively effective scheme of the status monitoring fault pre-alarming of approval that obtains.Have concurrently in addition easy for installation, the multiple advantage such as debugging is simple, and maintenance cost is cheap.System can link up reaching 255 nodes, has that partial discharge of switchgear detects and the comparatively comprehensive ability in localization of fault aspect, and the client can remote access system monitoring analysis result by network, the continuous monitoring of enforcement to crucial electric power asset.
And this product adopts at present popular transient state ground voltage (TEV) and ultrasound wave (AE) to detect the method for shelf depreciation, switch cubicle is realized to uninterrupted monitoring in 24 hours, thereby the potential safety hazard of having avoided switch cubicle to cause due to electric discharge, this product has powerful background data base, can realize lasting the data analysis comparison, whether cabinet that intelligent decision is surveyed surpasses early warning value, and by GPRS, data are uploaded to host computer in time, notify the related personnel, pay close attention in time or maintenance, avoided unnecessary potential safety hazard and economic loss.
The utility model has the advantage of: Intelligent switch cabinet detection system described in the utility model, adopt real time on-line monitoring, avoided unnecessary librarian use and economic the loss by advanced technological means, realization truly in office, just can observe in region within the jurisdiction the operation of all websites and security situation.Increase work efficiency, reduce failure rate.Effectively ensure power supply safety and reliability, reduced personnel cost and the wasting of resources.
