Although some dust intrusion won’t not affect the function of the telecom power supply equipment, the intrusion of dust is much more serious when the equipment is placed outside. Too much dust invasion will affect product life or product function. Especially in the northern part of China where often occur sandstorms . If the products are likely to be in the attack of sandstorms, it is necessary to have dust protection measures.

Dust is seamless, so the dustproof is closely related to the structure and packaging of the product cabinet. The working efficiency of the rectifier module is about 90%, and the efficiency of the inverting module (UPS) and the DC/DC module is over 80%. At the same time, the battery will generate heat when charging or discharging, which means that 10% to 20% of the energy must be distributed outward in the form of heat. There are two kinds of heat dissipation in outdoor telecom power supply system: ventilation and shell heat dissipation. Therefore, there are two basic ways for the design of the outdoor cabinet:

Air cooling type
The hot air is forced by the fan. In order to prevent dust, the dust filter network should be installed at the inlet and outlet. Because the filter network is easily blocked by dust. Once it is blocked, the exhaust heat will fail. The power will probably be protected by overheating and shutdown due to the heat can not be emitted and the internal temperature rises. Therefore, it is necessary to clean the filter network dust regularly in order to prevent the filter from blocking.

Enclosed type
The products are encapsulated in all kinds of circuits, completely using the package shell to dissipate the heat, so that it can be very well dustproof. Because of the lead-acid batteries in the products, although these batteries are known to be sealed, in fact, a small amount of corrosive gas (H2SO4) has been emitted. If the battery and circuit are sealed together, these trace of the corrosive gases will corrode the circuit in the long run, reducing the life of products, so the product can only be closed together, each module circuit.

A rectifier is a device that converts AC to DC, and can be used for power supply and detection of radio signals. The rectifier can be made from vacuum tube, ignition tube, solid silicon diode, mercury arc and so on. On the contrary, a set of devices that convert DC into AC is called inverter.

In the standby UPS, only the battery needs to be charged, no need to supply the load, so only the charger. In the dual transform UPS, the device both supplies the power supply for the inverter and recharges the battery, so it is called the rectifier.

Rectifier is a rectifying device. It has two main functions. First, the alternating current (AC) is changed into a direct current (DC), which supplies the load or supplies the inverter after filtering, and second, provides the charging voltage to the battery. As a result, it also acts as a charger.

1.Energy saving, low consumption and green environmental protection are the development direction of the industry
Low energy consumption and green environmental protection have become the development direction of the UPS industry. Along with the gradual promotion of the national energy strategy and information strategy, as the key equipment of information construction, UPS’s high efficiency, energy saving, low c

2.The trend of integration demand will be further strengthened
With the progress of science and technology, users are no longer satisfied with the power protection function of single UPS. They begin to care about the reliability and availability of the whole power supply system, and care for supporting the physical infrastructure and operational efficiency of the whole data center. The integration demand of downstream customers to the products and services of UPS vendors will guide the equipment provider to provide the corresponding solutions. The future main UPS manufacturer is no longer only a single UPS supplier, but a provider of the
overall power quality solution.

3.Cooperation with the upper and lower reaches will be further strengthened
To participate in the competition in the global market, UPS manufacturers must strengthen the integration of upstream and downstream resources and optimize the existing marketing network. By strengthening cooperation with upstream, will enhance the resource integration ability of enterprises, and enhance their competitive advantage in terms of quality assurance, price alliance and collaborative production. By strengthening cooperation with downstream channel providers and industry customers, will closely integrate our own marketing service network and local sales channels, which will better understand customer needs and better adapt to the changing needs of users. The strengthening of the cooperation between the upper and lower reaches will make the market influence of the main manufacturers expand continuously, thus gaining wider market space.

4.Industry concentration will be further improved
With the UPS industry competition intensifies, poor level of equipment, low management level, lack of core competitiveness of enterprises will be forced to withdraw from the market, to accelerate the industry reshuffle, but also has some strong R & D strength, large production scale and brand manufacturers to obtain greater expansion opportunities and market space, UPS industry the concentration of the future will be further improved.

5.The application of homologous technology in the field of new energy
The core technology used by UPS is the inverter technology, which can convert the unstable electric energy into a stable power. The solar inverter technology, which is the same as the UPS inverter technology, is widely applied in the wind turbine generator converter technology. It is a green technology of “new energy, energy saving and environmental protection”, which is actively encouraged by the state, and is in line with the future development trend. It is foreseeable that the application scope of the core inverter technology in the future UPS field will be increasingly expanded.
