Shenzhen Shajing transformer installation company said that in the actual power consumption, because of the power loss and the large gap between peak and trough power consumption, it is easy to cause the output voltage of the transformer to fluctuate. The ups and downs of the power supply voltage have a great impact on the performance, production efficiency and product quality of various electrical equipment. In order to ensure the qualification rate of the power supply voltage, it is necessary to adjust the output voltage of the transformer in time. Next, Shenzhen Shajing transformer installation company will introduce the steps of transformer voltage regulation. Let's have a look

1. Power failure. Disconnect the load on the low-voltage side of the transformer, open the drop fuse on the high-voltage side with an insulating rod, take necessary safety measures, unscrew the protective cover of the tap changer of the transformer, and place the locating pin in the neutral position

2. When adjusting the gear, adjust the tap changer to the corresponding position according to the output voltage:

when the output value of the transformer is lower than the allowable value, adjust the tap changer from gear I to gear II, or from gear II to gear III

when the output value of the transformer is higher than the allowable value, adjust the tap changer from gear III to gear II, or from gear II to gear I

3. After adjusting the gear, measure the DC resistance of each phase winding with a DC bridge, and check whether the current between the windings is balanced. If the difference in resistance between the phases is greater than 2%, it must be readjusted, otherwise after operation, the dynamic and static contacts will heat up due to poor contact and damage the transformer

with the maturity of power technology, the voltage also gradually tends to be stable, and there is no need to frequently adjust the transformer to disconnect key projects: COFCO Biochemical Co., Ltd. plans to invest 851 million yuan in the 30000 ton polylactic acid product project; Changchun bicecheng biomaterials Co., Ltd. plans to invest 174 million yuan in the 60000 ton biological thermoplastic composites and products project; Changchun Shengda biomaterials Co., Ltd. plans to invest 22million yuan in the 10000 ton bio based fully degradable plastic packaging film special material modification and product project; Changchun Leiguan environmental protection plastic products Co., Ltd. closed the 700 ton degradable plastic products project with a planned investment of 11million yuan. If we want to adjust the output voltage of the transformer, many regulations related to phthalate plasticizers have been issued internationally, which should be done by experienced technicians
