preparation example Construction

[0025] The preparation method of the deicing agent for power transmission lines of the present invention comprises the following steps:

[0026] Step 1, add sodium chloride, ammonium chloride and potassium oxide to soda ash and stir and mix evenly to obtain powdery mixture A;

[0027] Step 2. After mixing trichloroacetic acid and other components, heat and dry at 80°C for 20-30 minutes, and then crush it into powder to obtain mixture B;

[0028] Step 3. Stir and mix mixture A and mixture B evenly under dry conditions to obtain the ice-melting agent.

Embodiment 1

[0031] Get 58 grams of sodium chloride powder and 23 grams of soda ash, 4 grams of ammonium chloride and 3 grams of potassium oxide and mix evenly to obtain powdery mixture A, then mix 11 grams of trichloroacetic acid and 1 gram of sodium benzoate at 80 ° C Heating and drying at low temperature for 20 minutes, and then breaking into powder to obtain mixture B, and finally stirring and mixing mixture A and mixture B under dry conditions to obtain 100 g of ice-melting agent.

Embodiment 2

[0033] Get 53 grams of sodium chloride powder and 20 grams of soda ash, 7 grams of ammonium chloride and 6 grams of potassium oxide and mix evenly to obtain powdery mixture A, then mix 13 grams of trichloroacetic acid and 1 gram of sodium benzoate at 80 ° C Heating and drying at low temperature for 23 minutes, and then breaking into powder to obtain mixture B, and finally stirring and mixing mixture A and mixture B under dry conditions to obtain 100 grams of ice-melting agent.

Abstract

The invention discloses an ice melting agent for an electric transmission line. The ice melting agent is powdery solid and is mainly prepared from the following ingredients in percentage by mass: 53 to 60 percent of sodium chloride, 20 to 23 percent of sodium carbonate or sodium bicarbonate, 4 to 7 percent of ammonium chloride, 3 to 6 percent of potassium oxide and 11 to 13 percent of trichloroacetic acid. The ice melting agent for the electric transmission line provided by the invention can achieve the technical effect of fast ice melting. At the temperature of 5 DEG C, the ice melting speedin the primary ice melting stage can reach 63.3 mL / min and is much greater than the ice melting speed of 24.5 mL / min in the primary ice melting period of calcium chloride type ice melting agents; thedefect of the existing ice melting agent is solved. Meanwhile, due to the existence of jelly materials, the electric transmission line can be protected; secondary icing of the electric transmission line can also be prevented; the excellent ice removal and snow thawing capability can be realized.

Description

technical field [0001] The invention relates to the technical field of deicing power transmission lines, in particular to a deicing agent for power transmission lines and a preparation method thereof. Background technique [0002] The icing of power grid transmission lines is a widely distributed natural phenomenon. Every winter in mountainous areas, there are many accidents of downed poles and disconnection of transmission lines due to severe icing and strong winds, which pose a serious threat to the safe operation of the power system. For the deicing of transmission lines, the current common deicing methods can be basically divided into three categories: thermal deicing, mechanical deicing and natural deicing. In practice, manual deicing is the most commonly used method. , but there is also the dielectric loss of the ice itself caused by the excitation of about 33kV and 100kHz, which can melt the ice on the ice-coated transmission line. There is also the latest high-curren...
