1. As mentioned above, the function of the ring cabinet is simple, it is to connect different power parts, generally do not use it to realize the control, protection and measurement of specific electrical equipment; If you really need these things, it must be you choose the wrong, should choose the cabinet; Where there is high pressure, high pressure measurement should be given priority over low pressure measurement; When there is no way to measure it, low pressure measurement is considered. At this point, the low voltage measuring cabinet should be placed in the front of the low voltage entry line, behind the transformer, from the surface, it is not under the protection of Jilianggui, but in general, it should be in the transformer.
2. The core current Transformer does not have a primary winding of its own structure. The load current leads from L1 to L2 act as a primary winding through a circular(or other shape) iron core made of rolling Silicon steel. The second winding is wrapped directly and evenly around the circular iron core, and the secondary load of the current coil, such as the instrument, relay and transmitter, forms a closed loop in series. On the other hand, the less the number and the larger the ratio, the rated current is more than I1/n: type I1 -- a rated current at the time of the on-ramp; N-Number of heart-piercing.
3. Multihead current Transformer. This type of current Transformer, the primary winding unchanged, in the winding of the secondary winding, the addition of several pumps to obtain multiple variations. This type of current Transformer, which has no change in the primary winding, is added several pumps to the secondary winding to obtain multiple variation ratios. It has an iron core and an on-ramp ratio fixed primary winding. The secondary winding can be connected with an insulated copper wire around the insulation tube on the core of the suit, and the different types of current are drawn out of the secondary winding and connected to each terminal. Switching the connection of the secondary terminal to change the change ratio without changing the current Transformer is convenient for use.
