Technical requirements for explosion-proof distribution box

<

1. The electrical components in the distribution box/cabinet shall comply with their respective requirements and shall also maintain their electrical clearance and creepage distance under normal conditions of use; the exposed live conductors and terminals in the box.
2. The electrical clearances and creepage distances or impulse withstand voltages shall at least comply with the relevant provisions of the electrical components to which they are directly connected.
3. Explosion-proof distribution box is suitable for applications such as explosion-proof power distribution box and explosion-proof lighting distribution box. Explosion-proof distribution box products adopt composite structure, switch box adopts explosion-proof structure, bus box and outlet box use increased safety type. structure. Cast aluminum alloy shell, built-in high breaking miniature circuit breaker, with overload short circuit maintenance function and can increase leakage maintenance and other functions according to requirements. Module structure, a variety of loops can be freely selected combination. Special requirements can be tailored, pipe or cable wiring can be. skills requirement:
4. All the electrical components in the distribution cabinet meet the IEC309-1 and IEC309-2 and DINEN60309CEE17 international specifications, and the GB11918-2001 and GB11919-2001 specifications. The electrical switch adopts ABB products, the terminals adopt Finikes products, and the socket adopts. Mennekes products.
5. The structure of all distribution boxes, electrical device components, and circuit layout must be safe, reliable, easy to operate, and easy to maintain.
6. Distribution box should be equipped with locks and keys.
7. The distribution box adopts the lower entry line and the lower exit line. It has a knockout hole. The size of the knockout hole is determined according to the cable type in the drawing, and it is equipped with a sufficient number of rubber washers.
8. Distribution box enclosure protection: IP55 anti-acid anti-corrosion and waterproof)
9. The distribution box is made of stainless steel box (the stainless steel is Baosteel 304 or above). The color is stainless steel and the box thickness is not less than 2.0mm.
10. The operating switches, gauges and sockets shall be arranged on the front panel of the cabinet/cabinet for ease of operation; the housing and partition of the socket box shall include latching means for the door, and the socket parts shall have sufficient mechanical strength to be able to accept normal use. External forces encountered; anti-corrosion measures should be taken to suit the plant environment.
11. Copper busbars shall be used for the busbars, and copper wires shall be used for the busbars to the outlet terminals and outlets. The terminals, cabinets and screen inner external conductor terminals must meet the normal operating current, the copper row's current carrying capacity should be more than 1.5 times the rated current carrying capacity, and can withstand not less than the short-circuit withstand current of the electrical components in the cabinet. There is enough space for wiring. 9 The air switch and disconnector in the box must meet the requirements of dynamic and thermal stability.
The electrical clearance and creepage distance or impact withstand voltage should at least comply with the relevant provisions of the electrical components directly connected to it.

Organic Perilla Seed Oil

1. Lower lipids and blood pressure

The rich linolenic acid in Perilla Seed Oil can reduce serum cholesterol, triglycerides, low-density lipoprotein and very low-density lipoprotein, thereby inhibiting thrombosis and preventing myocardial infarction and cerebral infarction. In addition, α-linolenic acid Acid can also reduce blood viscosity, increase blood oxygen-carrying capacity, inhibit the synthesis of triglycerides, and increase the metabolism of various lipids in the body. Therefore, perilla seed oil has a particularly obvious effect in lowering lipids and blood pressure, especially for hyperlipidemia. and borderline hypertension, the effect is more prominent.

2. Protect liver

The α-linolenic acid in perilla seed oil can effectively inhibit fat synthesis, break down fat and excrete it from the body. Daily consumption can prevent the formation of fatty liver.

3. Strengthen the brain and protect eyesight

CCTV's "Encyclopedia Quest" reported that α-linolenic acid is one of the basic raw materials for nerve cell synthesis and a key nutrient that determines the development of human intelligence. It is called "brain gold". Correct supplementation of linolenic acid can improve the IQ and intelligence of infants and young children. Increase by 20%-30%, pregnant women and children must supplement.
