Embodiment 1

[0018] A photovoltaic power metering box, which includes a box, and the box is prepared according to the following process:

[0019] Step 1) Mix chlorinated butyl rubber, EPDM rubber, methyl vinyl silicone rubber, polycarbonate and glass fiber according to the mass ratio of 100:60:30:20:1 to obtain a mixture, and mix The materials were blended in a single-screw extruder, granulated to obtain the base resin, and then entered into an internal mixer for banburying. The banburying temperature was 70°C and the banburying time was 3 minutes to prepare the main material;

[0020] Step 2) Mix silicon carbide and alumina according to the mass ratio of 2:1, put them into a ball mill and grind them to 200 mesh powder, which is auxiliary material 1;

[0021] Step 3) Mix molybdenum disulfide and graphite at a mass ratio of 2:1 to obtain a mixture, then add it to N-methylpyrrolidone, which accounts for twice the weight of the mixture, and stir at 300 rpm for 5 minutes to obtain auxiliary ma...

Embodiment 3

[0032] The performance test of the box body of the photovoltaic power metering box prepared by the present invention:

[0033] 1. The tensile strength, elongation at break, high temperature resistance, flame retardancy, and insulation performance of the boxes prepared in Example 1 and Example 2 of the present invention are better, and the specific test results can be seen in Table 1:

[0034] Table 1

[0035]

[0036] 2. Corrosion resistance: soak the box body material in 10% dilute hydrochloric acid solution or 8% sodium hydroxide solution or 8% sodium chloride solution for 480 hours, there is no obvious change in the appearance and performance parameters. The box material has good acid, alkali and salt resistance.

The electric power metering box comprises a box body, wherein the box body is prepared from the following raw materials: chlorinated butyl rubber, ethylene propylene terpolymer, methyl vinyl silicone rubber, polycarbonate, glass fiber, silicon carbide, aluminum oxide, molybdenum disulfide, graphite, N-methyl pyrrolidone, kieselguhr, kaoline, an anti-aging agent 2246 and a hindered phenol antioxidant. Through improvement on a plastic material, the comprehensive performance of the electric power metering box for photovoltaic power generation is improved, and the application range is wide.

Description

technical field [0001] The invention belongs to the field of power metering devices, and in particular relates to a photovoltaic power metering box. Background technique [0002] As one of the emerging clean and efficient energy sources, photovoltaic power generation has become an effective way to promote the application of clean energy and can gradually replace some old power generation devices and technologies. The power meter box is an instrument used to measure electric energy, also known as watt-hour meter, fire meter, electric energy meter, kilowatt-hour meter, and refers to an instrument for measuring various electrical quantities. The box mainly plays the role of protecting the internal parts of the meter, which requires good mechanical properties, good thermal stability and flame retardancy. [0003] At present, flame-retardant ABS is mostly used as the shell material of the box in China. Although flame retardant ABS is cheap, its rigidity is not very good. Chin...
