Problems solved by technology

This device can realize early warning of fuse failure, but each failure will cause power failure at the load end, and not every failure will cause fuse failure, which is prone to misjudgment, causing unnecessary losses, and no prevention Preventive measures for fuse failures cannot fundamentally solve such failures

Embodiment Construction

[0033] Further description will be made below in conjunction with the accompanying drawings.

[0034] see figure 1 , the measurement and communication unit collects the voltage and current signals of the fuse, analyzes and processes them, and sends the analyzed and processed data to the computer in the information center through wireless transmission. Realize on-line monitoring of fuses, can effectively judge fuse failures, and deal with them.

[0035] see figure 2 , the geographical information of each fuse is set in each measurement communication unit, and each measurement and communication unit, the computer in the information center and the GSM communication terminal constitute a fuse fault monitoring and fault judgment system.

[0036] see image 3, a metering PT fuse fault monitoring device, including a power management unit 3, a data measurement unit 1, a central information processor 2, a GSM communication unit 4, a GSM communication terminal 5, a computer 6, and a...

Abstract

The invention relates to a fuse fault monitoring system, which is mainly characterized in that: a data measurement element installed on a fuse measures voltage data and current data on the fuse; the voltage data and the current data are processed by a central processing unit; and a processing result is sent to a computer of an information center through a global system for mobile communication (GSM) module, so a monitor can timely find and handle a fuse fault. In the invention, geographic information of each fuse is recorded into a central processing unit corresponding to the fuse, a fault fuse can be quickly positioned, a fault type and corresponding measures can be provided, so the fuse fault can be reduced, the maintenance time is saved, the loss caused by the fuse fault is reduced, and the running stability of an electric power system is improved.

Description

technical field [0001] The invention relates to the field of online fault monitoring of electrical equipment, in particular to a method for fault monitoring and fault judgment of metering PT fuses. Background technique [0002] Fuses have the characteristics of simple structure, easy installation and replacement, and high cost performance, and have been widely used in the electric power industry. However, due to other faults in the system and the defects of the fuse itself, the fuse has a fuse failure, especially the fuse failure of the metering PT fuse, resulting in less metering of electric energy and causing major economic losses to the power sector. Therefore, on-line monitoring of metering PT fuses, timely detection of abnormal operating status of fuses and potential hidden troubles, is an important means to improve the reliability of power supply and reduce economic losses in the power sector. Since the fuse blowing time is short and the faults are random, it is the k...
