Problems solved by technology

[0002] At present, short-circuit trips and power outages frequently occur on the low-voltage side busbars of transformers due to small animals and foreign objects overlapping between phases. The original heat-shrinkable insulation sleeves need to be disassembled and put on heat-shrinkable insulation sleeves, which are heated on site at high temperature. Bake the sheath until it shrinks before installing the device
It is labor-intensive and time-consuming, and because it is not resistant to aging, its reliability cannot be guaranteed for a long time
Due to the need for good insulation performance and anti-aging, ordinary adhesives cannot be used for the bonding of transformer low-voltage side busbar sheaths

Embodiment Construction

[0006] The invention comprises the following steps: adding 40-60 parts of fluorine-containing hydroxyl polydimethylsiloxane into a sealable kneader, adding 20-30 parts by weight of reinforcing filler, and 20-30 parts by weight of anti-corrosion filler, 1-3 parts by weight of pigment is heated up, heated to 180 degrees, and decompressed to 0.095MP A After processing for 4 hours, after being milled and passed three times by a three-roller machine, transfer to a double planetary agitator, add catalyst weight parts, crosslinking agent 1-3 weight parts, react for 2 hours, start the hydraulic press under nitrogen protection, and glue Press fit into a sealable tube.

[0007] The trade name of the catalyst is methyl tributylketoxime silane.

[0008] The trade name of the crosslinking agent is dibutyltin oxide.

[0009] The fluorosilicone para-aramid fiber is a rubber compound.

[0010] The pigment is ferric oxide, chromium oxide or titanium dioxide.

[0011] The anti-corrosion fil...

Abstract

The invention relates to a method for producing adhesive glue for a busbar sleeve at low voltage side of a transformer. The method comprises the steps of adding a base material- fluorine-containing hydroxyl dimethyl silicone polymer into an airtight kneading machine, adding reinforcing filler, electric corrosion resistant filler and pigment, raising the temperature, heating up, treating for 4 hours at reduced pressure, milling three times by a three-roller machine, transferring into a stirrer with double planets, adding a catalyst, reacting for 2 hours by a cross-linking agent, starting a hydraulic machine under nitrogen protection and pressing the adhesive glue into an airtight pipe. The method is simple and is convenient to use.

Description

technical field [0001] The invention relates to a production method of adhesive glue, in particular to a production method of adhesive glue for the busbar sheath on the low-voltage side of a transformer. Background technique [0002] At present, short-circuit tripping and power outage accidents frequently occur on the low-voltage side busbars of transformers due to small animals and foreign objects overlapping between phases. The original heat-shrinkable insulation sleeves need to be disassembled and put on heat-shrinkable insulation sleeves, which are heated on site at high temperature. Bake the sheath until it shrinks before installing the device. It is labor-intensive and time-consuming, and because it is not resistant to aging, its reliability cannot be guaranteed for a long time. Due to the need for good insulation performance and anti-aging, ordinary glue cannot be used for bonding the low-voltage side busbar sheath of the transformer. Contents of the invention [...
