12kV Fast Current Limiter

IEE-Business Product Introduction

A switching device with extremely fast breaking speed

Reduce the investment in substations

• Solve the short-circuit current problems encountered during the construction of new substations and the expansion of existing substations.

• When paralleled with reactors, it is the most economical and effective way to limit short-circuit currents.

• An ideal method for interconnecting switch cabinets and substations.

• The only technical solution in most cases.

• Reliability has been verified in the operation of thousands of engineering projects.

• Has been put into use worldwide.

• The short-circuit current will never reach the maximum expected peak value.

• The short-circuit current is restricted during the initial rising stage.

Functions

With the growth in global energy demand, there is a need for higher-power power supplies, additional transformers and generators, and increased interconnection between independent power grids. This often leads to short-circuit currents exceeding the allowable values of equipment, resulting in dynamic and thermal damage to the equipment. Replacing existing switchgear and cable connections with new equipment that has a higher short-circuit current withstand capacity is usually technically infeasible or uneconomical for users. However, using fast current limiters to reduce short-circuit currents in new or existing systems not only solves the short-circuit capacity problem but also saves investment. Due to their slow operation, circuit breakers cannot provide protection against the excessive peak value of the first half-cycle of short-circuit currents in the system. Only fast current limiters can detect and limit the short-circuit current at the initial stage of its rise (within 1ms), so that the maximum instantaneous value of the actual short-circuit current flowing through is much lower than the expected peak value. Compared with complex conventional solutions, fast current limiters applied in transformer or generator feeder circuits, whether as bus connections or bypass current-limiting reactors, have technical advantages and economic benefits. In power plants, large industrial facilities, and grid substations, fast current limiters are ideal switchgear in all aspects for solving short-circuit current problems.
