Description
Technical Field
The invention relates to the field of transformers, in particular to an open type high saturation voltage transformer which clamps a cable and is convenient to install.
Background
The mutual inductor is also called instrument transformer, and is a general name of current mutual inductor and voltage mutual inductor. The high voltage can be changed into low voltage, and the large current can be changed into small current for measuring or protecting the system. Its function is mainly to convert high voltage or large current into standard low voltage (100V) or standard small current (5A or 1A, both referring to rated value) in proportion, so as to realize standardization and miniaturization of measuring instrument, protection equipment and automatic control equipment. Meanwhile, the mutual inductor can also be used for isolating a high-voltage system so as to ensure the safety of people and equipment; saturation is the iron core magnetic flux that is too large, and when the excitation current increases, the iron core magnetic flux no longer increases linearly or no longer increases. The occurrence of saturation of the inductive transformer is related to the ratio of voltage to frequency. The voltage is over-voltage or the frequency is too low, so that saturation can be caused, and the voltage transformer can not be saturated under the conditions of rated voltage and standard frequency as long as the voltage transformer is not overloaded.
The cable is placed to the center through the cooperation between the upper portion and the lower portion of the existing open type mutual inductor, the purpose that one end is hinged to rotate and the other end is controlled to lock is usually adopted in the cooperation between the upper portion and the lower portion, but the opening direction is limited when the open type mutual inductor is opened, the open type mutual inductor is inconvenient to open under some special conditions, the upper portion and the lower portion are completely separated through the other method, then the upper portion and the lower portion are fixed through other methods, the portions which need to be taken down in installation are separately placed, and the open type mutual inductor is inconvenient to use under the inconvenient environments such as high altitude.
