Problems solved by technology

At present, the intelligence of transformer monitoring devices used in power transformation and distribution systems in my country is not high. The monitoring method of the main transformer operating in the substation still uses the traditional relay high-voltage control method, and is used in the main control room of the substation. The central signal screen is used for monitoring, and each control signal must be connected to the central signal screen with cables
This traditional monitoring method requires special personnel to monitor, the labor intensity of the staff is high, and t

Embodiment Construction

[0027] refer to figure 1 , the present invention is a system that uses a computer to remotely monitor transformers in power transformation and distribution systems.

[0028] In this system, the multi-channel terminal type signal collector 20 is a bus terminal, which includes digital input and output terminals, analog input and output terminals, special function terminals and communication terminals, and its main function is to collect various signals of transformers, Including transformer temperature, gas pressure, start and stop of cooling unit, etc. The bus terminal can adopt various commercially available field bus terminals. The present invention adopts the products of German Beckhoff Company, wherein the digital input and output terminals can adopt KL1002, KL1012 and other models, which can be used for transmission and monitoring of 5VDC, 24VDC, 48VDC, 120V AC / DC, 230AC and 400VAC and other signals. Analog input and output terminals can use KL3062, KL3022 and other mod...

Abstract

The invention relates to an intelligent remote monitoring system for transformer in power distribution system. The system includes multi-path terminal type of signal collector and multi-path coupler that connects computer controler center to each transformer. The signal collector is type of bus terminal including terminals for inputting and outputting digital quantity, terminals for imputting and outputting analog quantity, special functional terminal and communication terminal. The coupler is bus type. Plug-joint type of connection is adopted by each component piece. The remote monitoring the transformers is power distribution system is realize by using computer in the invention. The invented system provides features easy to collect accurate data, reliable control, normally running system without watching.

Description

technical field [0001] The invention relates to a transformer for a power transformation and distribution system, in particular to an intelligent remote monitoring system for a transformer of a power transformation and distribution system which is networked with a computer and realizes real-time monitoring by a remote computer. Background technique [0002] In the power transformation and distribution system, the transformer is one of the most commonly used and most important equipment, and the monitoring of the transformer is an important condition to ensure the normal operation of the power transformation and distribution system. At present, the intelligence of transformer monitoring devices used in power transformation and distribution systems in my country is not high. The monitoring method of the main transformer operating in the substation still uses the traditional relay high-voltage control method, and is used in the main control room of the substation. The central si...
