There are many kinds of protection for baoding dry type transformer. For the protection of dry type transformer, there is one kind of protection, namely differential protection. It is an important way to protect transformer from various faults and losses. The differential protection of the dry type transformer is relatively sophisticated. As long as there are dangerous signals or factors that are adverse to the current and voltage, the power supply will be cut off and a warning will be issued, which is its main feature and an important type of protection. What is the differential protection of baoding dry type transformer? Here we give you a detailed introduction:
For transformer equipment, the differential protection of baoding dry type transformer is the main protection of transformer. The transformer differential protection is mainly used to protect the transformer windings of double or triple windings and various kinds of interphase short faults occurring on the winding and its leading line.
The current transformer is installed on both sides of the winding transformer. The second side is connected according to the circulating current method. That is, if the equal end of the current transformer on both sides is facing the bus side, the equal end is connected and connected in parallel between the two wires to access the current relay. The current flowing through the relay coil is the secondary current difference of the current transformer on both sides, that is to say, the differential relay is connected to the differential loop. The range of transformer differential protection is the electrical equipment between the current transformer which constitutes the transformer differential protection and the conductor connecting these equipment. Since the differential protection does not operate on the fault outside the protection zone, the differential protection does not need to cooperate with the protection of adjacent elements outside the protection zone on the action value and time limit, so the instantaneous action can be performed in the fault inside the zone.
Baoding dry type transformer differential protection is the protection of all the most accurate one, as a result of baoding dry type transformer differential protection is basically by its various parts are protected, as a result of the baoding dry type transformer differential protection type, more complex work, accurate, has become common for installation of an important protection type.
