Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a circuit breaker characteristic test connection device. Background Art

[0002] With the development of circuit breakers, various circuit breaker testers have emerged, and the circuit breaker and the circuit breaker tester are usually connected using a test line.

[0003] In traditional technology, most DC field circuit breakers use graphite contacts. Due to the mechanical characteristics of graphite contact circuit breakers, special test lines need to be used. The test lines have special interfaces. Take the Kocos test line and the Wuhan Dayang test line as examples. The Kocos test line is a special test line for graphite contact circuit breakers. The voltage line of the Kocos test line is an ordinary ten-meter line, and the current line uses a connector with a unique shape. The Wuhan Dayang test line integrates the current line and the voltage line into an aviation connector, which makes the two test lines unable to be shared.

[0004] Although this method can connect the circuit breaker and the circuit breaker tester, due to the special connector of the graphite contact circuit breaker test line, it cannot be extended using an ordinary ten-meter line. At the same time, when the test instrument receives the signal inside, the return resistance of the instrument test will increase, and the internal signal of the instrument will always be that the circuit breaker is in the disconnected state.

In addition, the present application is applicable to universal test lines for different circuit breaker time parameter and speed characteristic test instruments, and localizes the KOCOS test line, so that a set of test lines can not only be applied to imported KOCOS instruments, but also to multiple sets of domestic instruments and equipment, thereby improving the adaptability of the test line, reducing the pressure of test instrument management, and reducing the test cost. At the same time, the test line meets the basic requirements of low resistance and large current, increases the length, improves the adaptability of the test line, expands the application scenarios of circuit breaker special test instruments, reduces personnel safety risks, and improves test efficiency.
