Abstract An intelligent alarm device of high-voltage switchgear is developed based on ARM in this paper. It is mainly collected the switching alarm signals of the high-voltage switching circuits in the high-voltage switch circuit by the device, such as low pressure in the air chamber, overheating of the motor, etc., it is firstly collected and processed through signal conditioning and optical coupler isolation technology, ARM series low power microprocessor as the main control chip, which is used to control the sound and light alarm of the local lamp screen, outputs the passive signal of the switching quantity, transmits the alarm signal to the relay protection system of the main control room. It is used as control and state acquisition, so that users can discover and eliminate it in time, prevent expansion of the fault, effectively reduce maintenance costs.
