Embodiment 1

[0017] A power distribution box, which includes a box, and the box is prepared according to the following process:

[0018] Add brucite to the crusher in turn for crushing, then mix it evenly with quartz sand at a mass ratio of 1:1, and then grind to obtain a powder with a particle size of 20 microns, which is the material 1;

[0019] Mix diatomaceous earth and kaolin according to the mass ratio of 2:1, then calcinate at 700°C for 10 minutes, then take it out and pulverize to obtain material 2;

[0020] Molybdenum disulfide and graphite were mixed according to a mass ratio of 2:1 to obtain a mixture, then added to N-methylpyrrolidone accounting for twice the weight of the mixture, and stirred at 300 rpm for 5 minutes to obtain material 3;

[0021] Take wood powder, phenolic resin, polyvinyl alcohol, glass fiber, white oil and carbon fiber, put them into the reaction kettle, mix well, then raise the temperature to 90°C, keep it warm for 3 minutes, cool naturally, then add mater...

Embodiment 3

[0031] Box material performance test of the present invention:

[0032] 1. The box body material prepared in embodiment 1-2 is made standard test piece by test standard, carries out following performance test, and the results are shown in Table 1:

[0033] Table 1

[0034]

[0035] Anti-radiation performance: After testing, the shielding rate of the box material to X-rays and ultraviolet rays can reach more than 80%.

[0036] Corrosion resistance: soak the cabinet material in 10% dilute hydrochloric acid solution or 6% sodium hydroxide solution for 360 hours, there is no obvious change in appearance and performance parameters.

Abstract

The invention belongs to the distribution equipment field and discloses a power distribution box. The power distribution box comprises a box body. A box body manufacturing technology comprises the following steps of step1) crushing and grinding; step2) calcining and crushing; step3) mixing and stirring; and step4) stirring, kneading, sizing and demolding. The distribution box possesses a good electromagnetic shielding performance difference, good insulating performance and the like, and an application prospect is wide.

Description

technical field [0001] The invention belongs to the field of power distribution equipment, in particular to a power distribution box. Background technique [0002] The power distribution box is a kind of distribution box. The power distribution box is divided into the power distribution box and the lighting distribution box, which is the final equipment of the power distribution system. The distribution box is a closed or semi-closed cabinet in which switchgear, measuring instruments, protective appliances and auxiliary equipment are combined and installed according to the requirements of electrical wiring. It usually includes a box body and a box door. The shaft connection makes a closed environment in the box, and the electrical components are installed in the box to prevent moisture and protect the internal instrument lines. Most of the existing distribution boxes are made of metal and painted on the outside. Due to long-term exposure to rain and sunlight, the large dis...
