Energy-saving transformers have very prominent advantages in terms of technical performance. China is currently vigorously promoting the popularization stage, but it is not optimistic about market acceptance. Power transformers are the key electrical equipment for power transmission. Transformer losses account for 30% to 40% of the power grid losses, while all transformers in China account for more than 3% of the national power generation. Therefore, the state has been focusing on energy saving and consumption reduction of transformers and has been vigorously promoting energy conservation and emission reduction.
As early as August 21, 2012, the State Council issued a detailed draft of the “12th Five-year Plan for Energy Conservation and Emission Reductionâ€, which clarified the specific goals and investment plans for energy conservation and emission reduction during the 12th Five-Year Plan period, and required the reduction of power transformer losses during the 12th five-year period. Which no-load loss decreased by 10% to 13%, load loss decreased 17% to 19%.
On November 6, 2012, the Ministry of Finance, the National Development and Reform Commission, and the Ministry of Industry and Information Technology issued Cai Jianjian [2012] No. 854 to issue the Implementation Rules for the Promotion of Energy-Saving Products Huimin Engineering High-Efficiency Energy-Saving Distribution Transformers. The “Implementation Rules†divides the scope and conditions of promotion products, promotion of enterprise conditions, promotion deadlines, promotion and subsidy standards, promotion qualification applications, subsidy fund applications and disbursement, and penalties. The promotion product is a three-phase 10 kV application pressure level. Non-excitation regulator, energy efficiency grade 2 and above, rated capacity of 30 kVA to 1600 kVA oil-immersed type and rated capacity of 30 kVA to 2500 kVA dry type transformer.
In fact, the transformer energy efficiency standard is one of the focuses of power standardization work. In 2005, the power industry introduced a guideline for the economic evaluation of industry-standard distribution transformer energy efficiency technologies, which played a positive role in promoting the replacement of old transformers and lowering of energy efficiency. Fortunately, the current energy efficiency standard for 10-kilovolt three-phase distribution transformers has been submitted for approval; the guideline for the economic evaluation of the energy efficiency of distribution transformers has been implemented since July 1, 2013; the design guidelines for transformers' environmental awareness since June 2013 It will be implemented on the 1st.
Gear Reducer Motor is a small precision reducer, and the size and specification can be customized below 38mm. Shenzhen shun cheong electrical co., LTD. 15 years engaged in the design, development, manufacture Dc Gear Motor, products applicable to the smart home, widely used in intelligent robot voice interaction, children's education escort robot, intelligent sweeping machine robot, intelligent robot adaptability, independent motor, intelligent medical robot project.
Application field:
Method of use: the best stable in horizontal plane, installed on the gear reducer motor output shaft parts, cannot use a hammer to knock,knock prone to press into the gear reducer motor drive, may cause damage to internal components, and cannot be used in the case of blocked.
Operating temperature range:
Gear reducer motor should be used at a temperature of -10~60℃.
The figures stated in the catalog specifications are based on use at ordinary room temperature catalog specifications re based on use at ordinary room temperature (approximately20~25℃.
If a geared motor is used outside the prescribed temperature range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.Depending on the temperature conditions ,it may be possible to deal with them by changing the grease of the motor's parts.Please feel free to consult with us about this.
Storage temperature range:
Gear reducer motor should be stored ta a temperature of -15~65℃.
In case of storage outside this range,the grease on the gearhead area will become unable to function normally and the motor will become unable to start.
Service life:
The longevity of gear reducer motor is greatly affected by the load conditions , the mode of operation,the environment of use ,etc.Therefore,it is necessary to check the conditions under which the product will actually be used .The following conditions will have a negative effect on longevity.Please consult with us should any of them apply.
â—Use with a load that exceeds the rated torque
â—Frequent starting
â—Momentary reversals of turning direction
â—Impact loads
â—Long-term continuous operation
â—Forced turning using the output shaft
â—Use in which the permitted overhang load or the permitted thrust load is exceeded
â—A pulse drive ,e.g.,a short break,counter electromotive force,PWM control
â—Use of a voltage that is nonstandard as regards the rated voltage
â—Use outside the prescribed temperature or relative-humidity range,or in a special environment.
â—Please consult with us about these or any other conditions of use that may apply,so that we can be sure that you select the most appropriate model.
when it come to volume production,we're a major player as well .each month,we rurn out 600000 units,all of which are compliant with the rohs directive.Have any questions or special needed, please contact us, we have the engineer group and best sales department to service to you Looking forward to your inquiry.
