Description

technical field [0001] The invention relates to a circuit breaker function test device, in particular to a cost-controlled circuit breaker function test intelligent test device, which belongs to the technical field of circuit breaker testing. Background technique [0002] A low-voltage circuit breaker, referred to as a circuit breaker, is a switching device that can not only switch on and off normal load current and overload current, but also switch on and off short-circuit current. In addition to the control function in the circuit, the low-voltage circuit breaker also has certain protection functions, such as load, short circuit, undervoltage and leakage. According to the needs of my country's power supply network intelligence, the State Grid Corporation of China requires the power supply network intelligence. Therefore, it is necessary for the terminal actuator of the power supply network—the fee-controlled circuit breaker to execute the upper-end signal to have the func...
