The purpose of s11 oil-immersed transformer quick-break protection is to get rid of overcurrent protection in close proximity to the switch power supply end of the protection equipment posture period long, choose to enhance the rectification value to limit the posture scope of the method to maintain route.
There are three kinds of protection scope: working voltage quick-break protection, current quick-break protection, transformer differential protection quick-break protection. Many electronic products are a rated voltage, can not exceed the rated voltage, or it will burn the special equipment.
Therefore there are some machines and equipment on the electric flow protection module, when the electric flow exceeds the set electric flow situation, the machine and equipment automatically power off, in order to maintain the machine and equipment.
Zero sequence protection means that after the ground fault is generated in the large short-circuit capacity grounding protection, there will be zero sequence current, zero sequence voltage and zero sequence output power occurs, the use of this amount of electrical equipment consists of maintenance of grounding short-circuit generation group is commonly known.
Long-term overload makes the distribution equipment s11 oil-immersed transformer temperature rise, the temperature rises, the oil malignant, the insulation layer decreases, drives the electromagnetic coil insulation layer and the insulation resistance between the iron pin aging, reduces its use period, incinerates the processing distribution equipment s11 oil-immersed transformer.
