Functional requirements:

The communication SSPC mainly has the following functions:

a) Front end single-phase two hundred and twentyV AC power input, distributed by AC SSPC to branch loads, load capacity one hundredVA~5kVA (1A, 2.5A, 5A, 10A, twenty-threeA, a total of five specifications):

b) When a short-circuit fault occurs in the branch load, the AC SSPC will quickly take short-circuit protection measures to avoid affecting the common grid load, prevent the fault from expanding, and avoid significant drops in the input side voltage waveform;

c) When a nonlinear load surge occurs in the branch, the AC SSPC will quickly take corresponding overcurrent limiting measures to avoid significant impact on the AC power grid side:

d) Capable of self checking and identifying faults (overload, short circuit, etc.)

DC SSPC mainly has the following functions:

a) Front end 24V DC power input, distributed to branch loads by DC SSPC, with load power ranging from two hundredW to 2kW (5A, 10A, 20A, 42A, 83A, a total of five specifications);

b) When a short circuit fault occurs in the branch load, the DC SSPC will quickly take short-circuit protection measures to eliminate the impact on the common grid load, avoid the expansion of the fault, and avoid significant drops in the input side voltage waveform:

c) When a resistance capacitance load surge occurs in a branch, the DC SSPC will quickly take corresponding overcurrent limiting measures to avoid significant impacts on the DC grid side:

d) Capable of self checking and identifying faults (overload, short circuit, etc.)
