Description
Technical field
The present invention relates to a kind of Industrial Process Monitoring device, especially relate to a kind of Gases Dissolved in Transformer Oil on-Line Monitor Device.
Background technology
Power transformer is one of important operational outfit of electric system, and whether very large on electric power netting safe running impact its normal operation is.From crash analysis, a lot of accidents are that local fault expands the burst accident causing.But at present the criterion of equipment operation condition is depended on to preventive trial, because the preventive trial cycle is long, existing preventive trial project is insensitive to the developing fault reaction of insulation.And speed of development often can not find in time in the local defect of a few days to a few weeks, this local defect even expands the accident causing in shorter time in several weeks and account for larger proportion in Accident of Transformer statistics.Therefore, the on-line monitoring of enforcement transformer has become an important component part of insulation diagnosis.
The system reform of existing China electric system, has higher requirement to the reliability of electrical network transmission of electric energy and economy on the other hand, requires to use minimum cost, builds and has enough transmission and distribution networkses of reliable level.At present transformer online monitoring equipment can't solve can improve reliability, again can effectively control the cost of overhaul, rationally extension device serviceable life etc. problem.
Utility model content
The purpose of this utility model is to provide a kind of Gases Dissolved in Transformer Oil on-Line Monitor Device, solves equipment dependability not high, and the cost of overhaul is high, and serviceable life is short, monitor discontinuous, the problem of the easy loss of the not high gas of precision.
To achieve these goals, the utility model provides a kind of Gases Dissolved in Transformer Oil on-Line Monitor Device, Gases Dissolved in Transformer Oil melting concn is monitored, comprise the gas-oil separation module of integrated setting in housing, gas detection module, data acquisition fault diagnosis module, power module and display module, gas-oil separation module is separated output electrical signals in rear inflow gas detection module Gases Dissolved in Transformer Oil, the concentration value that electric signal calculates mixed gas automatically according to Demarcate Gas data after by the collection of data acquisition fault diagnosis module shows on display module, power module provides power supply to device.
Described data acquisition fault diagnosis module is also provided with wireless communication module and/or the communication interface based on TCP/IP procotol, is separately also provided with eight toggle switchs and sets address.
Gas detection module comprises gas sensor and drift correcting circuit, and the drift of drift correcting circuit automatic calibration gas sensor, is provided with lighting module on display module.
The top inlet valve of gas-oil separation module and transformer, bottom fuel outlet valve, radiator loop or circulating-pump outlet end are connected.
The beneficial effects of the utility model are:
1, install easy for installationly, need not have a power failure, instrument is directly installed on transformer valve.Installation site can be positioned at top inlet valve, bottom fuel outlet valve and radiator loop, circulating-pump outlet end place.The oil of installation site preferably can have convection circulation, so that on-line monitoring instrument can be reacted to power transformer interior fault in time.
2, integrated apparatus design concept, device can depart from background computer isolated operation, installs integrated degree high, innerly containing communication and gas concentration analytic function, reduces unnecessary communication controller, and device communication port can conveniently be realized many networking operations.
3, sensor fluctating automatic calibration, gas sensor is along with the prolongation of service time will inevitably bring drift, thereby produces certain measuring error.This product is compared with transformer online monitoring product on current domestic and international market, and maximum technological innovation is that device can automatic correcting sensor drift before each measurement.
4, consumptive material and maintenance need not be regularly replaced, with the comparison of on-line chromatograph quasi-instrument, the easily-consumed products such as carrier gas need not be regularly replaced, need not regular calibration instrument.
5, multiple communication modes, can realize many transformer online on-line monitorings, wired or wireless communication, and configuration GSM communication function, user can grasp Site Detection data by mobile phone the very first time, realizes real unmanned.
6, liquid crystal display and human induction switch, when technician's execute-in-place, liquid crystal is lighted demonstration automatically, and the keyboard operation of device band is easy to use.
Anti-interference strong, stable performance
7, device can meet outdoor various severe running environment requirements, can resist the various electromagnetic fields of transformer station, radio wave interference simultaneously, and product detects test by national quality testing center electromagnetic compatibility.
8, field device structural design is novel, possesses lightning protection, rainproof, moistureproof, anti-high temperature function.
Sample tap is located at device outside, draws oil sample conveniently.
