RET6701MRK002816-AB Interval layer measurement and control protection device refers to the automatic device configured according to the electrical interval in the substation to realize the measurement, monitoring, control, protection and other auxiliary functions of the corresponding electrical interval. It directly collects and processes the original data of the site, transmits it to the station control level computer through the network, and receives the control operation command issued by the station control level to realize the operation control of the device. In addition, the spacer layer measurement and control protection device can also independently complete the control operation of the circuit breaker and the isolation switch.

3. Advantages

Limit the influence range of the fault: the RET670 1MRK002816-AB spacer layer device is configured according to the electrical interval, so that the influence caused by the device failure is limited to this interval range and will not spread to other electrical intervals.

Narrow the monitoring object: the monitoring object is reduced from the entire substation to a certain electrical interval, which reduces the volume of the device and makes the installation method of the device more flexible.

Improve the reliability of the system: In addition to the traditional input and output functions, the device also integrates advanced functions such as simultaneous closing and anti-error interlocking, which improves the reliability of the power system.

Iv. Classification

In the hierarchical distributed substation integrated automation system, the spacer layer devices (or spacer layer units) can be roughly divided into the following categories:

Protection and control integrated device: a REC670 1MRK002814-AC is generally used in low and medium voltage (110Kv below) systems, such as transmission line protection and control devices, transformer backup protection and control devices.

Other specific equipment protection measure and control device: such as capacitor protection measure and control device, reactor protection measure and control device.

5. Application and significance

Spacer layer measurement and control protection devices are widely used in various equipment in the power industry, such as substations, distribution rooms, power transmission and transformation systems. Its application can improve the safety, stability and reliability of the equipment, so as to ensure the normal operation of the power system. In addition, the use of the device can also save human and material resources and improve work efficiency.
