Attentions in Use of Open and Close Mounted Transformer

发布时间:    浏览次数:次

    

  The open and close mounted current transformer is a precision transformer, and the following points must be taken into account during use:

  1. The appearance must be check for deformation before use, otherwise the precision of the test may be affected;

  2. Check if the end face of the iron core is clean before use, and wipe it with a dry silk cloth (alcohol and water are strictly prohibited);

  3. The use environment requires that it shall stay away from the strong magnetic field so as not to affect the test accuracy. The ambient temperature for use is -30℃~+40℃, and the relative humidity shall be less than 80%. It is strictly forbidden to use in the wet and corrosive gas environment;

  4. There is a clamping screw at the opening of KH series open and close mounted transformer, please tighten the screw after determining the installation location, to prevent the transformer from falling;

  The SKH series transformer is of split design, please pay attention to check the number when installing, install according to numbers. When installing, gently push and pull, do not push and pull vigorously, so as not to cause transformer damage which affects the use.

  Part of the transformer is equipped with support and installation accessories, please install firmly, so as not to drop the transformer.

  5. Polarity

  The KH series open and close mounted transformer (hereinafter referred to as the KH Series) has a current flow mark “→” at the label position, and the primary current shall pass through the transformer in the direction indicated by the arrow (namely, the tail face of the arrow is "P" and the primary current passes through the transformer from face "P").

  The SKH series open and close mounted transformer (hereinafter referred to as the SKH Series) has a mark of “P” on the shell, and the primary current passes through the transformer from face "P".

  When the output end is a terminal, S1 and face “P” are the same name ends; when the output end is a tail wire, the red (blue) wire and face “P” are the same name ends.

  6. Secondary open circuit is strictly prohibited in use;

  During the installation of the open and close mounted transformer, ensure that the transformer is installed only after the secondary circuit connection has been completed, so as not to cause the secondary opening of the current transformer.

  7. Secondary load shall not be too large.

  When the secondary current of the open and close mounted transformer is 5A, the secondary load is 2.5VA; if the secondary load is more than 2.5VA, the test precision will be affected.

  8. The end face of the iron core must be kept clean and closed in good condition in the process of use;

  9. Handle with care in use, prevent heavy objects from colliding so as not to affect the precision;

  10. After use, it must be preserved in a clean environment.
