10kV switchgear energy storage

Can high-voltage switchgear improve the reliability and safety of power supply?

In order to improve the reliability and safety of power supply and reduce the failure rate of switchgear, this paper designs a novel high-voltage switchgear which is reliable and safe.

What is switchgear used for?

Introduction Switchgear is used for power generation, transmission, consumption, distribution, and energy conversion in the power system to play the role of on–off, control and protection. Switchgear is developing towards high voltage, high current, miniaturization, and long life.

What is the maximum temperature rise of a switchgear?

The heat field results reveal that even in the condition of passing through current with long operation time, the maximum temperature rise of the switchgear is 55.9 K and 48.7 K respectively, which is lower than the standard design requirement 70 K.

What is the model of high-voltage switchgear?

Overall model of new high-voltage switchgear. The busbars in the switchgear are tortuous and it is the focus of current-carrying loads so that its grid should be finely divided. While the shell of the switchgear has a large volume and does not require excessive fine division.

How does the cooling efficiency of the switchgear depend on convection heat dissipation?

As can be seen in Eq. (20), the cooling efficiency of the switchgear depends on the convection heat dissipation and the fan power. In this paper, the German ebmpapst A2E200-AI38-01 axial fan is selected, and its corresponding power curve is shown in Fig. 10.

How to improve the insulation of a switchgear?

It is determined that the connection and the corner is most likely to occur insulation problem, which the electric field is 1.23 × 10 6 V/m and 1.72 × 10 5 V/m respectively. Polishing connection and the corner is a good way to improve the insulation of the new switchgear.
