On-load voltage regulation tapping switch tester

The invention relates to an on-load voltage regulation tapping switch tester, which comprises a PC (personal computer), an ARM processor, a programmable gate array unit, a signal conditioning and sampling circuit, a sampling data memory, a high-voltage switch control circuit, a current sensor and a displacement sensor. The PC is connected with the ARM processor through an Ethernet interface. The ARM processor is connected with the programmable gate array unit through a network interface. The programmable gate array unit is connected with the signal conditioning and sampling circuit and the high-voltage switch control circuit. The programmable gate array unit is connected with the sampling data memory through a photoelectric coupler. The signal conditioning and sampling circuit is respectively connected with the current sensor, the displacement sensor and a high-voltage switch. The high-voltage switch control circuit, the current sensor and the displacement sensor are all connected with the high-voltage switch
