Product details
1、 Product Overview
There are different specifications and applicable scenarios for electric meter boxes. Choosing the appropriate meter box can maximize the functionality and efficiency of the product. At present, there are three main types of watch boxes on the market: plastic, fiberglass, and metal. ZhejiangZhenghongThe ZH series intelligent high protection meter box developed by Electric Co., Ltd. is mainly composed of polycarbonate transparent PC material and ABS engineering plastic; This composite material consists of two parts: a matrix made of polyester resin; Reinforced material (PC), also known as transparent PC material or fiber-reinforced polyester material. Transparent PC material and fiber-reinforced unsaturated polyester are composite materials based on unsaturated polyester resin. These two materials have the characteristics of insolubility, flame retardancy, and recyclability. These two typesThe material has become a high-performance engineering material through functional filler modification and reinforcement with special fibers. In developed countries such as Europe and America, this material has been widely used in the electrical field for decades.2、 Box design
The above advantages of the new meter box all stem from the characteristics of the fiber-reinforced polyester material itself. In addition, in terms of box design, this new type of electric meter box is also endowed with many characteristics that are different from metal boxes:◆ Ventilate the box with ventilation components to prevent excessive distilled water production
Ventilation components are left at the lower and upper ends of the cabinet doors and backboards, as well as between the top plate, cabinet doors, and backboards. With the help of the heat generated by electrical components, the space inside the box can be dehumidified, which can prevent the corrosion of metal parts inside the box and prevent leakage current.
◆ Combination design makes installation easy
The modular design not only makes installation simple,And it is easy to replace box components, simplifying spare parts storage.
3、 Usage characteristics
Thoroughly solve personal injury accidents caused by poor grounding of the box and overlapping of foreign objects;◆ Low comprehensive usage cost, one-time useInvestment is possibleUsed for more than 20 years (exempting metal box replacement time and accumulated costs);
The unique design of the box can effectively resist external impact;
The cost of recycling the box material is relatively high, and it canPrevent the occurrence of theft of the main body;
The splicing method can reduce the size of the boxMaintenance cost (can only bereplaceDamaged components);
Burning at high temperatures does not produce suffocating gases.
In short, the electric meter box made of fiber-reinforced polyester materialIt has many advantages such as good insulation, corrosion resistance, long service life, and easy installation.
4、 Scope of use
This product is widely used in urban and rural power grid renovation projects of State Grid, Southern Power Grid, provincial power companies, construction projects, real estate engineering projects, PetroChina and Sinopec, transportation and finance, railway and shipbuilding, aerospace, photovoltaics, enterprises and institutions, municipal and national large-scale engineering projects.
5、 Functional purpose
Automatically track and compensate for the overload operation rate of low-voltage power grid distribution transformers and types of power users, increasing distribution capacity by 15% -30% while reducing losses by 25% -50%, thus achieving the goal of improving voltage quality, reducing electricity consumption, and fully utilizing electricity. It is widely used in urban and rural power grid construction and renovation projects.
