Embodiment

[0015] The antifreeze agent of the present invention is prepared by adding fillers to methyl basic polysiloxane (commonly known as silicone oil). The mass percentage of the preparation ratio is that the methyl basic polysiloxane accounts for 95.23%; the filler accounts for 4.77%.

[0016] The molecular formula of the methyl basic polysiloxane (commonly known as silicone oil) is C15H32O3Si4.

[0017] The filler is metallic silver powder.

[0018] The metal silver powder is prepared by mass percentage of the following raw materials, zinc oxide 26.32%; aluminum oxide 21.07%; boron nitride 7.89%; silicon carbide 13.15%; aluminum powder 31.57%.

[0019] Test 1 of the present invention, the No. 2 main transformer of the 66kV substation was powered off for equipment inspection. Members of the scientific research team used the antifreeze agent in the temperature measurement system of the transformer. , Complete the monitoring work of transformer oil temperature very well.

Abstract

An antifreeze agent and its application in the temperature measurement system of a transformer, which is prepared by adding fillers to methyl basic polysiloxane; the mass percentage of the preparation is: methyl basic polysiloxane accounts for 95.23%; filler accounts for 4.77% . After the application of the invention, the damage probability of the transformer thermometer is greatly reduced. The problem of freezing and cracking of the oil tank temperature measuring system of the power transformer above 66kV in the prior art is solved. At the same time, improve the performance of the transformer oil temperature measurement system; ensure that the thermometer of the transformer oil temperature measurement system will not be frozen and cracked within minus 50°C; improve production efficiency and ensure the safe and stable operation of the power grid.

Description

technical field [0001] The invention relates to an antifreezing agent, in particular to an antifreezing agent used in a temperature measuring system of a transformer, and is mainly suitable for the temperature measuring system of an oil tank of a power transformer above 66kV. Background technique [0002] At present, the measurement method for measuring the temperature of transformer oil is to separate the transformer box from the special hole for temperature measurement of the transformer, put transformer oil in both containers, and use the transformer oil in the special hole for temperature measurement as heat conduction. At the same time, it is common in this field It is considered that only the same transformer oil as the transformer box can be filled in the special hole for temperature measurement to better complete the heat conduction temperature measurement. [0003] But in the prior art, because the specific gravity of water is bigger than transformer oil in cold win...
