  In recent years, the global market demand for transmission and distribution equipment has generally increased. According to research institutions, the power transformer expansion, economic growth and demand for electricity in emerging countries will drive the global power transformer market, from $10.3 billion in 2013 to $19.7 billion in 2020, with a compound annual growth rate. 9.6%.

  Demand for electricity in China, India and the Middle East has grown rapidly, and High Voltage Switch Cabinet Manufacturer has become the main growth driver for growth expectations in the global power transformer market. In addition, the need to replace and upgrade old transformers in North America and Europe has also become the main driver of the market. “The UK power grid is already very backward. Only when the grid is replaced and upgraded, the country will not have a power outage. Similarly, in other European countries, such as Germany, the grid and electronics are undergoing continuous renovation to achieve a stable grid supply. "There are analysts who say so.

  In the eyes of the industry, there are two factors in the growth of the global transformer market. On the one hand, the upgrading of traditional transformers will give rise to a large market share. The elimination of backward products can promote the effective development of bidding work. The economic benefits will show up. On the other hand, the development, manufacturing, sales, use and maintenance of energy-saving and intelligent transformers will become the mainstream, and new products will inevitably bring new development opportunities to the industry.

  Today, as China High Voltage Switch Cabinet Factory, simply talk about the daily maintenance recommendations of the high voltage switch cabinet.

High Voltage Switch Cabinet

  1. Do insulation work according to the environment

  Generally, the temperature range required by the High Voltage Switch Cabinet is between -10 °C and 45 °C. If the ambient temperature is too high, the electrical conductivity of the metal parts will below, and the electrical resistivity will increase, and the oxidation will gradually increase. The insulation strength of the insulating member is also lowered. Of course, an environment that is too cold will also cause large internal stresses on the components of the device, thereby damaging the reliability of the insulation. Therefore, it is necessary to add some reinforced insulation appliances and insulation protection measures according to the situation, and the surrounding environment requires no fire source, no pollution, no corrosive chemicals.

  2. Do the appropriate dust prevention and inspection

  The metal equipment used in the high voltage switch cabinet can be coated with suitable paints in order to prevent rust and corrosion. In order to eliminate the influence of dust on the insulation performance, the dust in the equipment should be cleaned regularly with a brush. Frequently operated electric gates should be regularly checked for looseness of the fixing screws, and lubrication and fastening work should be done.

  3. High voltage switch cabinet internal wiring should be reasonable

  Sometimes, due to production needs, it is necessary to temporarily electrify power from the switchgear for high-voltage equipment. In wiring, it must be in strict accordance with the electrical safety management regulations, and the conductors with good insulation performance should be able to fully meet the needs of the power load. Let the electrical professional operate, require the wiring to be smooth and not knotted, and there is no mutual entanglement between the wires and the wires, and a reliable grounding work is done. When the temporary power supply is not needed, it is necessary to promptly remove the newly added power supply facilities and clean the site.
