How does Switchgear Panel work?

Switchgear panel

Switchgear panel

The working of a switchgear panel depends on the effective functioning of its different components.

The main functioning parts of Metal-clad switchgear are the relay and the circuit breaker.

When a fault occurs, the relay swings into action by closing the circuit trip.

This is through the automatic disconnection of the fault line.

Next, the healthy and operative sections ensure there is a flow of the required normal supply load.

Through this, there is a smooth electrical supply throughout the equipment, ensuring there is no damage.

Overloading of the line inhibits the current from making an electromagnetic release action.

However, it initiates the production of heat by the thermal element.

The heater heats the bi-metal sheet causing it to bend upwards.

This pushes the lever upwards, making the hook to lock off.

This breaks off the primary contact, cutting power supply off.

By doing this, when there is an overload, it exceeds the set current causing the electromagnetic tripper to produce suction.

A combination of the suction and the impact lever results in the lap hook to rotate upwards around the

Shaft seat, thereby releasing the lock

What Types of Switchgear Panels are there?

The main types of Switchgear panels available include:

  • Low voltage switchgear panels. They connect and disconnects distribute and interrupt the current flow with a voltage of up to 600V
  • Medium Voltage Switchgear Panels. This Switchgear panel interrupts, connects and disconnect and distributes current with a voltage between 600V and 69kV
  • High Voltage Switchgear Panels. These switchgear panels connect and disconnects interrupt and distribute current with a voltage of between 69kV and 230kV
  • The air-insulated Switchgear panel uses air as the main insulation material.
  • Gas-insulated switchgear panel uses a special gas, FS6, as the main insulation material.

How do you Troubleshoot Switchgear Panel?

· Creepage and Clearance Distance

You need to carry out this test between the live parts of the MV switchgear and also its exposed conductive parts.

You measure the distance between the live parts using the different polarities.

Bolted connections, joints, unsuitable connectors minimize the initial insulation values.

· Protective Circuit Effectiveness

This helps in determining the safety of the MV switchgear.

This test also determines the occurrence of high fault current in case the conductor detaches accidentally.

Effective protective circuits need to withstand optimum short-circuit thermal stress, which happens as per the supply current.

· Current Transformer Core Test

You need to test the ration and polarity of the current transformer core and compare the results to the primary current injection. You need to perform this test phase by phase.

· Dielectric Test

The dielectric test is on the auxiliary circuits.

For this test, apply 500 voltage DC between the terminal blocks and the earth point.

· Voltage Tests on the Main Circuit

You need to check on the dielectric strength to remove causes like damage during handling, wrong fastening, and presence of foreign bodies.

Such issues may result in an internal malfunction of the switchgear of not addressed.
