Power cabinet sealing agent self leveling anti condensation

Power cabinet sealing agent self leveling anti condensationWe are all aware that in humid environments, various threats to indoor electrical facilities are becoming increasingly apparent, and the impact on the safe operation of electrical equipment is significant. In electrical engineering, when the relative humidity is greater than 80% RH, it is called high humidity; Excessive humidity is the main factor causing accidents in electrical equipment.

　　
Power cabinet sealing agent self leveling anti condensationBelow is a direct explanation of the construction method:

Anti condensation sealing agent is generally used for sealing the bottom of distribution cabinets such as ring main units. Generally, construction is relatively simple. Use a small amount of fireproof mud or silver electric adhesive cloth to seal the bottom of the cabinet where there are circuit leaks. Then wrap the excess circuit with adhesive cloth, and mix the sealing material AB and AB in a 10:1 ratio to pour directly into the bottom of the cabinet. If the box area is large, a scraper tool can be used to assist in the sealing material to disperse more quickly.

Calculation method for construction usage:

1. Preparation tools: electronic scale, mixer (electric), sealing material

2. Calculate the volume of sealing material to be used, for example: the size of the electrical cabinet is length and width: 50 * 50 cm, and the sealing thickness is 1 cm.

The density of polymer moisture-proof sealing agent is known from the manufacturer to be 1.05-1.1g/cm? What is the density of water 1.0g/cm? It is slightly denser than water.

The weight of the material used is: length x width x height x density=50 x 50 x 1 x 1.1=2750 grams, plus a little 5% loss, a total of 2887.5 grams, a total of 2.9 kilograms.

3. Cost calculation: For example, if the polymer moisture-proof sealing agent costs 100 yuan/kg, the cost of sealing a 50 * 50 * 1cm electrical cabinet is 290 yuan, excluding labor and other expenses.

4. Start mixing AB components, weigh them with an electronic scale, mix AB components in a 10:1 weight ratio, and stir evenly with a blender. If conditions permit, use a scraper, and if conditions permit, use an electric blender. Stir more evenly for 3 minutes. Engineering technicians can directly visually estimate the volume (but it is not recommended).

5. Pour the sealing material directly into the bottom of the box, wait for natural leveling, and let it cure naturally for about 2-3 hours. If the outdoor temperature is high, the curing will be faster.

6. Pack up the tools, lock the electrical cabinet, evacuate, and move on to the next one.
