Abstract
Description
Technical Field
[0001] The invention belongs to the technical field of secondary core penetration of current transformers, and in particular relates to a secondary core penetration cable guide device of a current transformer and a use method thereof. Background Art
[0002] The principle of current transformer is based on the principle of electromagnetic induction. The current transformer is composed of a closed iron core and winding. Its primary winding has few turns and is connected in series in the circuit of the current to be measured. Therefore, it often has the entire current of the circuit flowing through it. The secondary winding has more turns and is connected in series in the measuring instrument and the protection circuit. When the current transformer is working, its secondary circuit is always closed. Therefore, the impedance of the series coil of the measuring instrument and the protection circuit is very small, and the working state of the current transformer is close to short circuit. The current transformer converts the large current on the primary side into a small current on the secondary side for use, and the secondary side cannot be open. The secondary side penetration of the current transformer refers to the conductor to be measured passing through the center hole of the current transformer, thereby changing the transformation ratio of the current transformer. The specific number of turns of the penetration determines the number of times the conductor to be measured passes through. For example, one turn means that the conductor to be measured should pass through once, and two turns mean that the conductor to be measured should pass through twice. When using a current transformer, there is no cable guide device to pass the cable through the secondary side of the current transformer, making it difficult to pass the cable through the secondary side of the current transformer. There can only be one grounding point on the secondary side, otherwise it may cause shunting, resulting in increased measurement errors or affecting the normal operation of the relay.
