Current Transformer HPT
Introduce:
Protection current transformer measures the large current of the alternating current, it needs to be converted into a relatively uniform current for the convenience of the secondary instrument measurement.
Whether the current transformer can correctly transfer the primary current in the short-circuit transition process plays a decisive role in the correct action of the relay protection.
The protective current transformer mainly cooperates with the relay protection device, and provides a signal to the relay device to cut off the faulty circuit when a fault occurs in the line, so as to protect the safety of the power system.
Features:
Shell is made of flame-retardant, 140 temperature-resistant polycarbonate injection molding.
The iron core is made of directional cold rolled silicon steel strip.
The secondary conductor is high-strength electromagnetic enameled wire.
The product structure is novel, beautiful in appearance, easy to install,small in size, light in weight, high in accuracy, and large in capacity.
Applications:
It is used to collect low voltage overload and short-circuit signals, and is used with protection relays.
The primary measurement range is 200-6300A, and the secondary output is 5A, 1A. class:5P5,5P10,5P15,5P20
Collect low-voltage overload and short-circuit signals, which can be used in conjunction with the motor protection unit.
Used in places where there is no direct rain or snow, no serious pollution and severe vibration.
