Product details:

SPE-MS non-disturbance rapid switching device

Product application:

The incoming circuit of the mediumvoltage power grid, single or grouped power supply switching, used in situations where, in the event of a power outage or short circuit fault on the power supply side, it is necessary quickly switch to a backup power source to ensure the continuous power supply of important sensitive equipment.

Product features:

Fast speed: This device uses a fast vacuum circuit breaker to achieve a break time of less than 5ms, the fast switching controller can judge the fault type, fault current amplitude, voltage current phase angle, predict the time of current zero crossing, and complete the switching within 15~0ms, switching the power supply of the equipment from the fault power supply to the standby power supply.

No disturbance: The power supply switching is completed within 1-30ms by using a fast switching method, and the frequency difference, voltage difference, and phase angle difference between the motor terminal voltage and the standby power supply can be with minimal switching, and the current impact on the original fault system can be almost ignored.

Long life: The fast vacuum circuit breaker is a new type of fast switching, which has a simple structure and uses precise zero-crossing switching technology to greatly reduce the burning of the contact, and the mechanical and electrical life is greatly improved.
