Definition: The MCHNO2D1AB0004A relay protection device is an automated measure and device used to provide protection in the event of a power system failure.

Features:

Rapid fault removal: Automatically, quickly, and selectively remove the faulty components from the power system to ensure that the normal operation of other trouble-free parts is not affected.

Alarm signal: To respond to the abnormal operation of electrical components, and send alarm signals according to the operation and maintenance specifications, so that the system operator can take appropriate measures to deal with.

Cooperate with automatic device: MCHNO2D1AB0004A and other automatic devices in the power system (such as automatic reclosing device), as soon as possible to restore power supply and equipment operation, improve the reliability of power system operation.

2. Composition and principle

Composition: MCHNO2D1AB0004A relay protection device is mainly composed of a measuring part, a logic part and an executive part.

The measurement part: measures the relevant electrical volume input from the protected object and compares it with the given setting value to determine whether the protection should be activated.

Logic part: According to the logical signal output of the measurement part, it works according to the given logical relationship to determine whether the circuit breaker should be tripped or sent a signal, and the relevant command is transmitted to the executive part.
