摘要（英）：

The utility model relates to a main transformer protection tripping matrix outlet auxiliary tester which comprises a DC power supply VCC, a power supply switch K1, a timing switch K2, an operation indicating lamp, ten detection and sound-light alarm circuits with a same structure, and ten time timing and display circuits with the same structure. The operation indicating lamp is connected with the DC power supply VCC via the power supply switch K1. The input ends of the detection and sound-light alarm circuits are respectively connected with corresponding ends of a tripping pressing plate lower mouth of a detected relay protection device. The power supply end of the detection and sound-light alarm circuits is connected with the DC power supply VCC via the power supply switch K1. The input ends of the time timing and display circuits are respectively connected with a pair of dry contacts of a relay protection testing stand. The power supply end of the time timing and display circuits is connected with the DC power supply VCC via the timing switch K2 and the power supply switch K1 in turn. Advantages of the main transformer protection tripping matrix outlet auxiliary tester are that the main transformer protection tripping matrix outlet auxiliary tester is high in detection accuracy and sensitivity, safe and rapid to operate and easy to carry out.
