Abstract
The invention belongs to the technical field of transformer monitoring, relating to a monitoring system of variation condition of water in transformer oil. The monitoring system of the micro-water in the transformer oil comprises at least one micro-water sensor in oil, at least one micro-water monitoring terminal in oil, at least one work station server and at least one access-side client. A design mode of modularization and integration is adopted in the monitoring system; operation is simple; and the monitoring system can be used for high-precise measurement in a wide measuring range and has a function of convenient long-distance browsing.
Description
Technical field
The present invention relates to a kind of utility appliance of power equipment, especially relate to the monitoring system of little water in a kind of transformer oil.
Background technology
Enlarging day by day of structure and improving constantly of voltage apparatus grade along with power industry, the maintenance of transformer is more and more important, and wherein the moisture measurement in the transformer oil become transformer safeguard in a very heavy part, water cut in the oil has decisive action in essence in the safe operation of transformer, the content of moisture plays decisive influence to the insulativity of transformer oil, too much water cut will speed up the aging of insulating material in the oil, and reduction insulativity, and then cause the instability and the potential danger of equipment operation, can cause coil to produce arc ring and short circuit phenomenon when water content is big, even can blast in some cases etc.According to GB50150-2006 " Erection works of electrical installations Standard for handover test of electric equipment ", the measurement of minor amount of water must meet certain regulation in the oil.Micro-water content in the offline inspection insulating oil of laboratory, complicated operation is wayward, and especially oil and water separation link realizes that difficulty is big, and from getting oil to the complicated cost height of testing process, real-time is poor to the laboratory distance for transformer simultaneously; Online little water monitoring is effectively replenishing of the little water monitoring in laboratory and perfect.
Application number be CN200820056711 patent disclosure be used for the injector of transformer oil determination of moisture in a kind of gas chromatograph, this kind detection method is highly sensitive, interference is little, but operation is complicated, general technician be difficult to hold and equipment requirements higher.The present invention calculates wherein micro-water content by the variation of monitoring transformer oil specific inductive capacity, has realized online detection, and is simple to operate, the accuracy height.
Summary of the invention
The invention provides the monitoring system of little water in a kind of transformer oil, it comprises little water sensor at least one oil, is used for the variation of measuring transformer oil specific inductive capacity; Little water monitoring terminal at least one oil, it comprises the analog-to-digital conversion unit that the conversion of signals of little water sensor change detected in the oil can be become the changing value of micro-water content in the oil; At least one workstation servers, it comprises the monitoring of software unit that can collect and manage little water monitoring terminal data in each oil; At least one access end client computer is used for browsing or downloading the Monitoring Data of the little water monitoring terminal of each oil.
Wherein, little water sensor is the polyimide capacitive temperature sensor in the described oil; Little water monitoring terminal is transferred to workstation servers by RS485 bus or gsm wireless mode with Monitoring Data in the described oil; Described workstation servers are transferred to each access end client computer by Ethernet with the Monitoring Data of little water monitoring terminal in each oil.
The present invention has reached easy and simple to handle by the micro-water content in the on-line monitoring transformer oil, and the accuracy of measurement height can conveniently carry out the purpose of remote browse.
