High voltage and reliability: column high voltage vacuum circuit breaker has the characteristics of high voltage break, its arc extinguishing ability is strong, medium strength is high, single break high voltage, makes the number of series breaks required under the same rated voltage level than air circuit breaker or less oil circuit breaker less. , for example, 220kv SF6 circuit breakers only need 1 or 2 breaks, and air circuit breakers or less oil circuit breakers need 4 breaks.
Long life: using imported outdoor epoxy resin as external insulation material, makes the life of the column circuit breaker more than 15 years, good weather resistance, no oil, no SF6, meet the requirements of environmental protection.
Environmental protection: no oil, no SF6 design meet the requirements of environmental protection, is conducive to environmental protection.
Automatic reclosing function: has automatic reclosing function, can effectively avoid the power failure caused by instantaneous fault, makes the distribution network without the cooperation of the main station, can also automatically complete the fault isolation and power supply recovery function.
Easy operation: easy operation, can be manually divided/closed operation, can also be wireless remote control operation, remote control distance is greater than 50 meters.
Flexible communication interface: flexible communication way, support GSM short message, GPRS , CDMA general wireless, fiber , twisted-pair, , carrier and other wireless communication mode, supports a variety of communication protocol.
The main function of the column circuit breaker is to automatically cut off the current when there is an abnormal situation such as short circuit or overload in the circuit to protect the circuit and equipment from damage. This type of circuit breaker not only has automatic operation function, but also can be manually controlled, so as to achieve flexible management of the circuit.
