CHINT circuit breaker is a new type of leakage circuit breaker that integrates the functions of leakage relay, leakage circuit breaker, AC contactor, undervoltage and so on.
Product Features:
It can automatically distinguish between slowly variable leakage and abrupt leakage (electric shock) for protection. Maintain the advantages of phase and amplitude detection technology, so that when the three-phase leakage is unbalanced, the relative mutation leakage action value is consistent. Eliminates mutations, leakage, allergies, and insensitivity. It can operate with low line insulation levels, high leakage currents, and poor stability. The digital filtering technology is adopted to enhance the anti-interference ability and make the online operation more reliable.
Digital display of leakage current and fault indication for easy fault analysis and fault search. The numbers show the automatic score, the number of connections, the manual score, and the number of connections. Provide the evaluation basis for on-site operators for power system management departments. Intelligently identify short-term leakage and permanent faults, automatically reclose leakage in a short period of time, and automatically shut down when permanently faulty.
Prevent lightning from inducing high voltage into the low-voltage line and avoid damage to weak current equipment. It can automatically and intelligently track and set the safety value of the upper limit of the line slow leakage current, or manually set the slow leakage and abrupt leakage limits. Abnormal voltage protection, such as phase loss, overvoltage, undervoltage, etc. Significant energy-saving effect: effectively block leakage current and reduce line loss. High circuit breaking capacity. Using foreign advanced technology, it takes the lead in solving the defect that the circuit breaking capacity of similar products is too low, and the breaking current can reach 65KA (the maximum value of the breaking current of similar protectors is 10KA), so as to ensure the reliability of the circuit breaker (protector) under heavy load.
Long life. Using foreign advanced technology, it first solves the defect of short life of similar products (the maximum life of electrical equipment of the same type of protector is 100A3000 times, and more than 200A 1000 times). Significant reduction in operating costs.
The above are roughly the characteristics of CHINT circuit breaker.
