First, summary

DDS311 type single-phase electron type electric energy meter, developed on the electron type serial standard foundations of electric energy meter of limited company of southern electric wire netting in China, have adopted the super large-scale digital signal to deal with the chip, keep the storing device of information, advanced technology of encrypting etc. of isolating communication interface and infrared communication and information security of standard RS485 completely permanently. Realized the electric energy is measured, long-range control and putting and stealing functions such as the electricity,etc., meet electric department's standardization, the demands of electronization, automation, intelligent measuring and management.

Third, main function

1,Measure the function: Have, not reverse and the intersection of timesharing and meritorious electric energy measure function, store 12 historical the intersection of electric consumption and data for account day.

2,Measurement: Record parameters of running such as the voltage, electric current, power, power factor,etc. at present, the error does not exceed & plusmn; 1%.

3,The period of rate: Two sets of rates can time and change automatically, each set supports 8 periods of period, 4 rates.

4,Incident record: While recording the zero clearing incident, programming, school, lose the electricity, draws and shuts the floodgate, uncaps 10 times respectively.

5,Freeze the function: Freeze regularly, freeze instantly, agree to freeze, freeze in Japan, freeze on the hour.

6,Long range control: The built-in on-load switch can be carried on openly and cut out through RS485, and protect the electric function long-rangely.

7,Line zero is measured: The battle line is sampled separately, measure separately in Line zero; As the power differs by 10%, switch over automatically.

8,Safe protection: Programming switch and programming password are protected doubly, prevent it is not licensor's programming operation.

Manufacturing Co., Ltd's main management of electric energy meter of west strength of Hangzhou, the electric energy can count the case, the single-phase electron type electric energy meter, electric energy meter and power consuming information gather the system the terminal, electric energy measure the case, DDS311 type single-phase electron type electric energy meter of branched case of cable;

Manufacturing Co., Ltd's predecessor of electric energy meter of west strength of Hangzhou is a factory of kilowatt-hour meter of Hangzhou, firstly appeared in 1968, reformed system, registered on December 30, 1999, RMB registered capital is 60 million.
Company it specializes in electric energy meters and power consuming to be terminal to gather system in information and electric energy measure case, the intersection of cable and branched case,etc. mix the intersection of network and the intersection of automation and relevant research and development of product, produce and sell, already had a history of more than 40 years so far, it is a national-level new high-tech enterprise, successively made ISO9001 quality management system, ISO10012 measures management system, ISO14001 Environment Management System and OHSAS18001 job health and safety management system to authorize. West strength & ldquo;” Brand electric energy meter is the leading brand products of Zhejiang Province, west strength & ldquo;” The trade mark is a famous trade mark of Zhejiang Province.

Unit of incumbent Zhejiang Province managing director of employer's organization of instrument and apparatus of the company, branch's managing director's unit of the instrument and apparatus of electrician of Chinese instrument and apparatus employer's organization, standardized technology of national electrician's instrument and apparatus? ? ? Person last committee member unit meeting electric energy, participate in the country (trade) many times The standard is drafted, it is South Africa STS and Swiss DLMS technological association member.
The company complies with & ldquo; Based on quality, science and technology wins victory & rdquo; Management theory,regard science and technology as enterprise the sources of the developments, quality souls that enterprise survive, expense of the proportion go on new product development, technological transformation and scientific and technical innovation with higher than 6% income from sales every year, carrying on the maintenance, operation of company's quality certification system and improving, improving. The research and development technique center that the company set up in 2002 is research institute, provincial enterprise research and development centre and technique center of provincial enterprise at present, is equipped with in Germany EMH high-accuracy standard device, measures the standard testboard, tests apparatus and various dependability life-span testing equipment intactly and electromagnetic and compatibly, there is table taking the course of its own in trades that counts the operation laboratory of dependability; Have large quantities of to research and develop technicians while being high-quality, and regard developing in market demand and enterprise as the direction, launch every research and development, multiple technical research are in leading the level at home; There are 62 product design patents and 43 products software copyright card at present, 29 kinds of new products have passed the scientific and technological scientific and technical assessment of results of drawing room of Zhejiang Province, some scientific research projects are listed in the demonstration project of industrialization of national Torch Program, market & ldquo of Zhejiang Province, Hangzhou; Special & rdquo of technological innovation; , & ldquo; Enterprise's informationization employs & rdquo; , & ldquo; Industrialization & rdquo of new and high technology; Wait for the government to support specially and reward the project category, is well received by governments at all levels; And set up uniting laboratory and production, teaching, research project to cooperate with the technical colleges of University of Hong Kong, Zhejiang University, Zhejiang, rely on the academic advantage of university talent's information, offer the solid assurance for company's industry's technical development.
