Problems solved by technology

Typical converter transformer fire accidents show that none of the above three converter transformer Box-in noise reduction structures can fall off automatically in the event of a fire, seriously affecting external fire fighting
For example, in 2018, a fire in a UHV converter transformer lasted for more than 20 hours, causing serious equipment burnout

[0031] The nylon is nylon 66, the flame retardant is silicon dioxide with a particle size of less than 5 microns, the hydrophobic agent is polysiloxane with a particle size of less than 10 microns, and the anti-aging agent is aluminum oxide, calcium oxide , boron oxide, magnesium oxide, in the present embodiment, described antiaging agent is the calcium oxide that particle size is less than 3 microns, and described antistatic agent is in alkylsulfonic acid, phosphoric acid or dithiocarbamic acid A combination of one or more, in this embodiment, the antistatic agent is an alkyl sulfonic acid, and the anti-low temperature thickener is methyl cellulose, carboxymethyl cellulose, hydroxyethyl cellulose, One or more combi...

Embodiment 2

[0043] The difference between this embodiment and Embodiment 1 is:

[0044] The mass numbers of the components in this example are as follows: 18 parts of nylon, 5 parts of flame retardant, 3 parts of water repellent, 5 parts of antiaging agent, 2 parts of antistatic agent, and 2 parts of anti-low temperature thickener.

[0045] The antistatic agent is dithiocarbamic acid.

[0046] In step s1, weighing: according to the number of parts by mass, weigh 18 parts of nylon, 5 parts of flame retardant, 3 parts of water repellent, 5 parts of antiaging agent, 2 parts of antistatic agent, and 2 parts of anti-low temperature thickener ;

[0047] In step s2, mixing: adding the flame retardant, water repellent, anti-aging agent and antistatic agent to the mixer in sequence and mixing evenly; at the same time, heating the nylon to 275°C through the heating device and keeping it for 4 minutes to completely melt it; Then add the melted nylon and anti-low temperature thickener into the mixe...

Embodiment 3

[0050] The difference between this embodiment and Embodiment 1 is:

[0051] In this embodiment, the converter heat-melt support plate includes the following components by weight: 20 parts of nylon, 3 parts of flame retardant, 2 parts of water-repellent agent, 3 parts of anti-aging agent, 1 part of antistatic agent, anti-thickening agent at low temperature 3 doses.

[0052] The antiaging agent is aluminum oxide with a particle size of less than 3 microns, the antistatic agent is alkylsulfonic acid, and the anti-low temperature thickener is hydroxyethyl cellulose.

[0053] In step s1, weighing: according to the number of parts by mass, weigh 20 parts of nylon, 3 parts of flame retardant, 2 parts of water repellent, 3 parts of antiaging agent, 1 part of antistatic agent, and 3 parts of anti-low temperature thickener .

[0054] In step s2, mixing: adding the flame retardant, water repellent, anti-aging agent and antistatic agent to the mixer in sequence and mixing evenly; at the...

Abstract

The invention discloses a converter transformer hot-melt supporting plate and a preparation method thereof. The converter transformer hot-melt supporting plate comprises the following components in parts by weight: 15-20 parts of nylon, 3-8 parts of a flame retardant, 2-5 parts of a water repellent, 2-8 parts of an anti-aging agent, 1-2 parts of an antistatic agent, and 1-3 parts of a low temperature resistant thickener. The preparation method comprises the steps of weighing, mixing, filling, pressurizing, cooling and soaking. The converter transformer hot-melt supporting plate has the advantages that the converter transformer hot-melt supporting plate is automatically fused and falls off when a fire occurs in a converter transformer, so that the converter transformer is exposed, an external fire-fighting medium can directly act on a fire source conveniently, and damage to equipment and auxiliary facilities which explode at the initial stage of the converter transformer is reduced.

Description

technical field [0001] The invention relates to the field of converter converter noise reduction devices, in particular to a converter converter hot-melt support plate and a preparation method thereof. Background technique [0002] The converter transformer is one of the most important equipment in the converter station, and it is also the main source of noise in the station. The Box-in noise reduction device of the converter transformer is equivalent to reducing the sound source power from the source, which plays an important role in meeting the noise standard of the converter station. However, while the Box-in noise reduction device meets the noise reduction requirements, it also creates new problems. For example, when a fire occurs in the converter transformer, the closed Box-in noise reduction device hinders the effective function of the fire extinguishing medium during the external fire extinguishing process. Due to the fire source, especially the blocking of the top B...
