A method of forming a calcium chloride and aggregate composition includes providing a calcium chloride compound, adding an aggregate into the calcium chloride compound, and mixing the aggregate and calcium chloride compound to establish a mixed composition having the aggregate substantially uniformly suspended in the calcium chloride compound. The aggregate may comprise any suitable aggregate material, such as sand, salt or rock salt or the like. The aggregate may be mixed with the calcium chloride when the calcium chloride is in a paste form so as to substantially uniformly mix or blend the aggregate and calcium chloride and to substantially uniformly suspend the aggregate in the calcium chloride paste.

The invention discloses an integrated integrated fast switch type current limiter and a method for cooperating with a circuit breaker. The current limiter integrates a fast vacuum switch inside a current limiting reactor and electrically connects it in parallel. The cooperation method is: the current limiter control system monitors the short-circuit current of the system, and controls the fast vacuum switch to open, so as to realize the rapid limitation of the short-circuit current within 20ms. The short-circuit current is limited, and the fast vacuum switch closes after the circuit breaker completes the first opening. If the circuit breaker coincides with a temporary fault, the current limiter is in a micro-loss operation state; if the circuit breaker coincides with a permanent fault, the current limiter operates again, and the circuit breaker breaks the limited short-circuit current again. The invention realizes the integrated integration of the fast-switching current limiter, can greatly reduce its volume cost, and can effectively reduce the dynamic and thermal stability technical index of the current-limiting reactor at the same time.
