Figure 1 sound light alarm principle and Application
Supply line
According to the application and short-term plan within three years, the power supply can choose aluminum wire, thereby reducing an investment. Large scale use of aluminum wire will consume electricity and lead to a series of problems, so it is not recommended for more than three years of application. Reasonable selection of copper wire rod, through energy saving and cost saving, can generally be in three years to recover the higher part of the investment.
Compared with copper supply line, aluminum wire can cause the following problems:
1., the main line overheating, especially in the copper and aluminum joints, but because of the short life of aluminum wire, the problem will become increasingly serious.
2. the supply voltage is low because of the high resistance of the aluminum wire, especially after five years of use, the resistivity will rise rapidly. The main line adopts aluminum wire, which is the general practice of most agricultural production bases. It is suggested that the rectification should be carried out. Not only will it waste a lot of electricity (usually at 30 degrees per hour or more), but there will also be considerable security risks.
Power Distribution Box
The biggest difficulty in choosing the distribution box is that it does not provide the greenhouse special distribution box products for the greenhouse enterprises. The products which the enterprises can purchase are not professional and targeted.
The distribution box is divided into three grades, the first, is the enterprise of electrical assembly, is at a relatively low (because often see with unnecessary components and material is not reasonable, so the higher the cost), reliability is not high enough, the maintenance workload is large, suitable for this application within three years; second, is made in the electrical materials market, there is no design for greenhouse application characteristics, and the price is very high. Three years planning for the distribution box; third, is a professional distribution box provided by our company, the professional is reflected in the demand for greenhouse design and material selection, reasonable wiring, stainless steel box, and the price is moderate, suitable for ten year plan.
engineering construction
Due to the different Chinese and Europe, modern facilities planting industry development is not mature, has not yet appeared (Shanghai Zhi Nong core should be the first to provide light) professional design, construction and maintenance services of professional enterprises for agricultural enterprises. The Greenhouse Inc does not have the ability to bind to specific crop planting, provide design and service more segments, agricultural production enterprises have been set up on your own light, will make the process not up to the quality standard of ten years of application.
Proposal three years and above application planning, please professional team for construction, and signed several years of quality assurance and auxiliary maintenance agreement, can ensure to improve comprehensive benefits.
