Battery industry to actively promote technology innovation
In accordance with a new base stations to be equipped with a set of communication power laptop battery consumption is usually calculated, if the count of new operators to take over the replacement of the original power supply, then the 3G communication power requirements during the construction period at least more than 35 million units. But the telecom power supply industry in the face of the huge market potential, also need to face 3G brought about by a series of new problems.
3G industrial chain to actively seize the opportunity to
Full-service carriers will be the development of communication power supply market, and further rapid growth of pulling power. As an information network infrastructure and security equipment, communication power supply and other equipment usher in a very good opportunity for development. Another data shows that in the next five years, China's communication power supply market, the external environment will be further favorable direction. The whole building 3G base stations will be built nearly 350,000. In accordance with a new base stations to be equipped with a set of communication power consumption is usually calculated, if the count of new operators to take over the replacement of the original power supply, then the 3G communication power requirements during the construction 346970-001 period at least more than 35 million units. Expected that by 2012, communication power supply market size will reach 40 million units, sales of 50 billion, while the base station construction, UPS sales, is expected to reach a new peak.
3G network, building Jianzhan speed, power small power AC-DC power supply co-exist and so on. Low-power level of DC power supply and AC inverter power is bound to become a key technology platform for 3G network-powered products. Currently, power companies need to actively guide the integration of AC and DC operators use power, speed Jianzhan speed to meet different power requirements. As the 3G brought about by many of the new situation, 3G power supply products need the spirit of serialization and standardization of the direction, it is necessary to adapt to different operators, different demands on the power supply, but also in line with the needs of enterprise-scale production, rapid and large-scale operators to respond to Omnibook XE3 market needs.
Beijing Power Source Technology Co., Ltd. DC Power Supply Division, told reporters Yang Jun, deputy general manager, 3G's large-scale construction, so that operators have a certain communication power demand growth, while the new power supply is still in the exploration of ways phase. Power source based on 3G network operators to the different needs of the power to accelerate research and development speed, actively cooperate with the equipment operators to use small quantities to ensure that the new 3G products to market quickly to meet the practical engineering requirements.
3G is currently building in full swing, the increase of the phenomenon of a total of base stations, enabling operators to increasingly focus on miniaturization of the volume of F2024A power supply products.
Group pairs of Deng Zhou Ping, director of marketing, told reporters the current telecommunications room, the base station within the communications equipment tend to be small and lightweight, standards integration, safe and reliable. Particularly in the field of back-up power supply, required to adapt to the use of a larger temperature range, and better weight and size of energy ratio and longer life products. Substitute for the traditional lead-acid battery research for several decades, have never stopped, through the major breakthroughs in key technologies, iron, lithium batteries is gradually becoming the ideal small-capacity lead-acid battery substitutes. After double-posted the tireless efforts of several generations of researchers, in 2008, successfully developed communications lithium iron battery system for UPS uninterruptible power supply, broadband access, integrated cabinets, wireless base stations, FTTB, FTTH and other areas with a reliable back-up power supply F2024B guarantees.
A total of base station will pose new challenges
The "TD-building, for example, 3G base stations to the whole building and supporting equipment brought some new challenges." Tianjin, China Putian, deputy director of the Office of the fields pointing to a base station in Tianjin suburbs of the city, told reporters.
Under the guidance of the field, the reporter walked into this wall covered with barbed wire on the outskirts of the base station. Through the actual inspection, the reporter found, Putian, TD equipment and many years ago Motorola, par written for the production of GSM equipment, sharing the same room, air conditioning and power systems.
"TD-building, 90% of the base station sites, should be shared with the GSM." Fields, told reporters, "and sharing to the relevant facilities will bring some new requirements."
Schneider's of APC's China-related person in charge told reporters, TD and the vast majority of GSM base stations have adopted a total station site and to share a package of equipment, Omnibook XE construction nets, this should be the operator in order to save duplication of input waste, improve the efficient use of existing equipment concerned. For this standard with the base station contains two kinds of telecommunications, the power load is bound to be higher than a single base station signals, and with the increase in the local telecommunications users, the base station load will increase.
The Yang Jun has put forward different views, he told reporters, 3G equipment, power consumption typically small, operating only in the original power supply based on the expansion of the rectifier can meet the power requirements, basically there is not much communication power supply impact.
It should be noted, a total base station power programs, but still a certain degree of risk. Because the load on the two systems are put together, would be supporting equipment or other infrastructure to bring greater pressure on the event of overload, power failure or accidental human-induced accidents, F1739A the impact is double The.
Thus, for communication base stations, the choice of quality clearance and related ancillary equipment, communication power becomes critical.
Distributed base station programs that require special power supply
ZTE's TD Tianjin Office Project technical manager Zhang Lei in the Hongqiao District, Tianjin, Beijing-Tianjin inter-city high-speed railway next to an engine room told reporters, "As high-speed railway train running faster, RRU + BBU has been distributed base station widely used. "
He put his hand pointing to the engine room of the BBU baseband equipment, told reporters: "That's a BBU BBU placed in the engine room, a number of optical fiber connections RRU radio unit has been deployed in various places to strengthen the coverage."
Just as Zhang Lei said, because the 3G band used in generally high, resulting in poor penetration, as well as high-speed rail coverage and coverage of major sports OmniBook 6000 venues and other reasons, carriers are increasingly using distributed base station equipment and technology.
In order to TD indoor coverage, for example, in order to strengthen the effect of indoor coverage, telecommunications carriers, launched a radio-frequency technology and micro-cellular Zoom technology, key equipment of the power supply all have ongoing requirements. On the one hand, each device (power from 200W to 300W or so) are required to configure the appropriate UPS. The UPS power but also in the 1kVA around, allowing the main device to ensure 2-4 hours of electricity.
On the other hand, these RRU devices typically installed in the outdoor poles F2019B and H-type base station platform, so the UPS package to install under the conditions required to meet such a small size, light weight, wall-mounted, etc. to adopt stringent requirements.
Section Hengsheng sales center vice president of Lin Hua-min, told reporters, according to RRU's power requirements, the need for specialized RRU in accordance with the "three defenses" to design power supply equipment. First, to design an integrated chassis, integrated chassis need to contain the exchange of UPS and back-up battery, and supports two kinds of wall and floor installation. Second, as the special place the site in order to prevent misuse unrelated persons causing the battery to the line connection is bad, with special design uses a terminal to connect input and output lines. Thirdly, since the RRU field generally do not have air conditioning, therefore, an integrated chassis should have a certain F2019A degree of cooling.
