An embodiment of the invention provides an auxiliary plug board for a circuit breaker test. The auxiliary plug board for the circuit breaker test comprises a board body, wherein a contact plane is arranged on the board body; connection holes which correspond to pins on an aviation plug are formed in the contact plane and are connected with an output end of the auxiliary plug board; fixed columns which are in clamped connection with fixed bolts on the aviation plug are arranged on two sides of the board body; waterproof projections are arranged at the edge of the contact plane on the board body; and an infrared sensing module is further arranged on the contact plane. The auxiliary plug board is arranged between the aviation plug and followed-up power supply and control equipment, and directional transmission of different data in the aviation plug can be realized, so that a cover plate of a circuit breaker mechanism does not require to be opened during test; the number of operators is reduced; labor and time costs are reduced; closing and locking are not required to be relieved manually in a test process; and therefore, operation risks of maintainers are reduced.
