Abstract

The invention relates to a mechanical characteristic test system of a high voltage circuit breaker. A branch channel of a tester in the system is connected with one end of a second normally open switch, the other end of the second normally open switch is connected with a first test line connector, a combined channel of the tester is connected with one end of a fifth normally open switch, the otherend of the fifth normally open switch is connected with a second test line connector, and a common channel of the tester is connected with a third test line connector through a test line. The mechanical characteristic test system provided by the invention is provided with a control circuit to automatically switch the test channel during the test to realize the one-key test, an operator only needsto press a contact switch to perform one-button start on the test system, cooperative control is performed on the circuits by a relay, when the branch channel is tested, a first relay controls the combined channel to disconnect, when the combined channel is tested, a second relay controls the branch channel to disconnect, so that it can be ensured that the branch channel and the combined channelare not tested at the same time, therefore the test can be effectively protected from being damaged, the mechanical characteristic test system provided by the invention can be operated by one key, thereby being convenient and efficient, and manual operations can be effectively saved.

Description

technical field [0001] The invention relates to the field of electric equipment testing devices, and more specifically, relates to a mechanical characteristic testing system of a high-voltage circuit breaker. Background technique [0002] The mechanical characteristic test of the high-voltage circuit breaker includes the time parameter test of the circuit breaker, the operating voltage test of the opening and closing electromagnet, and the speed characteristic test of the circuit breaker. It is necessary to replace the test wiring several times during the test; since there are other secondary circuits on the terminal block where the control circuit of the circuit breaker is located, special care must be taken during the wiring process to prevent the secondary circuit from being short-circuited or grounded due to wrong terminals. [0003] At present, the common practice is to set a switch on the test line, and then change the position of the switch to switch the test items af...
