Embodiment 1

[0039] Such as Figure 1-Figure 3 A transformer oil-paper insulated intelligent dewatering system shown includes a drying barrel 1, an oil filter 2, an oil inlet valve 5, an oil outlet valve 3, a micro-water transmitter 6, a flow meter 8, an oil pump 7, a main controller, The man-machine interface and the upper computer, the oil outlet of the transformer oil tank 4 is connected to the oil inlet valve 5 through the pipeline, the oil inlet valve 5 is connected to the oil pump 7 through the pipeline, and the oil pump 7 is connected to the oil inlet interface of the drying cylinder through the pipeline , the oil outlet interface of the drying cylinder is connected to the oil filter 2 through the pipeline, the oil filter 2 is connected to the oil outlet valve 3 through the pipeline, and the oil outlet valve 3 is connected to the oil inlet of the transformer oil tank 4 through the pipeline;

[0040] Micro-water transmitter 6 is used to measure micro-water data in oil at oil inlet va...

Embodiment 2

[0048] Such as image 3 As shown, a transformer oil-paper insulation intelligent water removal control method described in Embodiment 2 is realized on the basis of a transformer oil-paper insulation intelligent water removal system described in Embodiment 1, including the following steps:

[0049] Step 1: Establish the above-mentioned intelligent water removal system for transformer oil-paper insulation;

[0050] Step 2: The main controller enters the pre-operation stage, including the following steps:

[0051] Step S1: the main controller reads the micro-water data collected by the micro-water transmitter 6 in real time, and at the same time, the main controller reads the flow data of the flowmeter 8 in real time;

[0052] The main controller takes the micro-water in oil data and flow data at this time as the initial data, stores them and displays them to the user through the human-computer interaction interface;

[0053] Step S2: the main controller opens the oil inlet val...

Abstract

The invention discloses a transformer oil paper insulation intelligent water removal system and a control method thereof, and relates to the technical field of transformers. The water removal system comprises a drying barrel (1), an oil filter (2), an oil inlet valve (5), an oil outlet valve (3), a micro water transmitter (6), a flow meter (8), an oil pump (7), a main controller, a human-computerinteraction interface and an upper computer. The invention solves the technical problem of effective online water removal. According to the invention, an operation stage is additionally set before thenormal operation of the water removal system, so that the water removal action can be well pre-operated before being executed, the working state of each module of the water removal system can be monitored in the pre-operation stage; therefore, the normal execution of the back water removal action is greatly ensured, and the water removal efficiency is improved. In addition, an operation stage isadditionally set after the normal work of the water removal system is finished, so that the situation of incompleted water removal is completely eradicated.

Description

technical field [0001] The invention relates to the technical field of transformers, in particular to a transformer oil-paper insulation intelligent water removal system and a control method thereof. Background technique [0002] The three major factors that affect the life of transformer insulating paper are moisture, oxygen and temperature, among which the role of moisture is the most obvious. [0003] How to remove the moisture in the transformer is one of the important means to prolong the life of the transformer at present. [0004] At present, none of the transformer water removal devices on the market can effectively remove water. The reason is that when the water removal device is turned on and off, the traditional technology adopts the method of directly turning on the water removal or directly closing the water removal, and there is no setting before operation. Pre-running and setting an additional water removal cycle after water removal lead to large measurement ...
