Product Details:

SPE-ZLB Loss Deep Current Limiting Device

Product Application:

For occasions where the short-circuit current is too large at the generator outlet, the low-voltage side of the main, the incoming line of the factory transformer, bus section, etc., it replaces the traditional current limiting reactor, avoids the loss caused by the reactor being long-term connected in in the system, and deeply limits the short-circuit current during a fault. It is a core equipment for high reliability power supply and low cost operation and maintenance.

Product features:

Fast response speed: Short-circuit current detection, judgment and current limiting can be completed within 7-1ms;

Large breaking capacity: The fast circuit breaker with eddy current drive is used, combined with the "current zero separation" technology and high-performance arc extingu chamber, the arc time is short, and the short-circuit breaking capacity can reach more than 80kA.;

High current limiting depth: The reactor with4%-100% reactance can be configured according to the system requirements, which greatly increases the system impedance during a short circuit and limits the fault current within the expected value when designing a new system, the selection standard of the load-side circuit breaker can be reduced by increasing the reactance rate, which significantly saves the equipment cost.

Zero energy saving: There is no electric energy loss during normal operation, which can greatly reduce the electricity cost of the enterprise compared with the traditional series reactor.

Long service life: The components adopt electromagnetic repulsion drive mechanism and permanent magnet maintenance technology, with long mechanical life, no heating and no wear during fault-free operation.

Integrated design: The and secondary separation structure is adopted, which eliminates the interference of the primary side temperature and strong magnetic field on the secondary control part, and improves the reliability of the control and drive module at the same time, based on the primary and secondary isolation, the secondary equipment cabinet can be overhauled under the condition of primary operation, which improves the power supply reliability and convenience.

High reliability: The fast circuit breaker is equipped with a forced closing module, which eliminates the damage to the device caused by the circuit breaker refusing to close
