With the development of the economy, motors consume a large amount of electric energy in our country every year. Now explosion-proof motors occupy a large proportion of industrial motors, so a slight improvement in the efficiency of explosion-proof motors can help our country save a lot of energy.
The standard GB18613-2012 "Energy Efficiency Limits and Energy Efficiency Levels of Small and Medium-sized Three-phase Asynchronous Motors" has been enforced since September 1, 2012. In this standard, the energy efficiency level of the motor (level 1, level 2, level 3), the limit value of energy efficiency, and the evaluation value of energy saving are specified. Level 3 is a mandatory index, and level 2 is the evaluation value of energy saving of the motor. The YB3 series motors currently promoted in our country's market only meet the mandatory indicators of Level 3 of this standard. From September 1, 2016, the standard's level 2 index will replace level 3 as a mandatory index, that is, the second-level energy efficiency explosion-proof motor will replace the third-level energy efficiency explosion-proof motor. At that time, YB3 series motors will not meet the requirements of this index. The current focus of work is to develop motors that meet the GB18613 level 2 efficiency level. With the development of science and technology in my country, new high-efficiency energy-saving explosion-proof motors have been produced, that is, YBX3 explosion-proof motors. The main performance indicators of YBX3 explosion-proof motors have reached or approached the international advanced level. Therefore, in the future, the second-level energy efficiency YBX3 explosion-proof motor will replace the third-level energy efficiency YB3 explosion-proof motor. The pace will be accelerated. Of course there will be immediate results in energy as well.
As far as the enterprise is concerned, changing the original low-efficiency explosion-proof motor into a high-efficiency energy-saving motor will also greatly increase the profit of the enterprise. Although the price of the second-level high-efficiency energy-saving explosion-proof motor will be more expensive than ordinary energy-efficient motors, as long as it operates normally, the power saving of one year can save the entire motor, and it can also save the country's burden. Therefore, it is very cost-effective for enterprises to choose YBX3 explosion-proof motors. Therefore, YBX3 explosion-proof motor will be the trend of explosion-proof motor selection in the future.
