The SPAE010 RS49301-MA relay protection device is a specific model of relay protection equipment mainly used for grounding fault protection of transformers, generators, and motors in power systems. The following is a detailed analysis of the relay protection device:

1、 Basic Overview

Model: SPAE010 RS493001-MA

Type: High impedance differential type ground fault protection relay

Application field: Widely used for grounding fault protection of transformers, motors, and generators

2、 Technical features

High impedance differential protection:

Stable protection is achieved through a resistor in the differential circuit to prevent misoperation caused by fault currents beyond the protection range.

When a fault occurs within the protection range, the two current transformers supply current through a differential current circuit to operate the protection function.

High stability and anti-interference ability:

The device has a short total operating time and high stability, and can resist various mechanical and electronic interferences.

Comply with the latest IEC standards to ensure the accuracy and reliability of protective actions.

Digital and Software Design:

By adopting digital and software design, the accuracy and long-term stability of protective actions have been improved.

3、 Technical parameters

(Note: Due to limited specific technical parameter information for the SPAE010 RS49301-MA model, the following parameters are based on the general characteristics of the SPAE010 series for explanation.)

Rated and test voltage:

The voltage for relay type certification may vary depending on the specific model, but generally has a wide voltage setting range (such as 0.4... 1.2 x Un).

Current carrying capacity:

The current carrying capacity at 0.5 seconds of connection and current carrying may reach 30A (specific values may vary depending on the model).

The current carrying capacity at 3 seconds of connection and current carrying may decrease to 15A (specific value may vary by model).

The continuous current carrying capacity is usually 5A.

Contact rating:

The tripping contact may have a rated voltage of 250V AC or DC.

Signal contacts may also have corresponding rated voltage and current carrying capacity.

Auxiliary power supply:

The auxiliary power supply voltage of the SPAE010 series may vary, but typically includes ranges such as 80V AC or DC.

Operation and disconnection time:

The running time of the relay may depend on specific settings and fault conditions.

The disconnection time may be relatively fast, such as 120ms, to ensure a quick cut-off of the fault current.

4、 Application scenarios

This relay protection device is mainly used in the following scenarios:

Grounding fault protection for transformers, motors, and generators.

In power systems that require high impedance differential protection to prevent equipment damage or system collapse caused by fault currents.
