The invention provides an energy supply system of a high-voltage direct current breaker. The energy supply system comprises an alternating current power supply, a cascaded energy delivery transformer,a cascaded interlayer isolation transformer and a low-voltage load-adjusting transformer, wherein the alternating current power supply, the cascaded energy delivery transformer and the cascaded interlayer isolation transformer are connected in sequence. The primary side or the secondary side of the interlayer isolation transformer is connected with the primary side of the low-voltage load-adjusting transformer, and the secondary side of the low-voltage load-adjusting transformer is used for being connected with energy-acquiring equipment of the high-voltage direct current breaker through an energy delivery cable; the primary side of the energy delivery transformer is connected with a first reactive compensation device, and a second reactive compensation device is connected between the secondary side of the interl
