Problems solved by technology
[0004] However, in the prior art, the testing of each alarm contact of the hydraulic high-voltage circuit breaker is performed manually, and the above-mentioned alarm contacts are tested by gradually reducing the hydraulic pressure supplied to the high-voltage circuit breaker by the staff. The process operation is complicated and inefficient

The invention relates to a contact sequencing device and relates to the technical field of automatic testing. The main technical scheme is as follows: a contact sequencing device comprises a common terminal binding post, N binding posts, a sequencing circuit and a display module; the common terminal binding post is used for connecting the common connection end of a circuit breaker, and the first binding post to the Nth biding post of the N binding posts are used to sequentially connect with the M alarm connection points which alarm in turn during the driving pressure drop with the circuit breaker; the display module is respectively connected with the output end of a first logic circuit to the output end of an Nth logic circuit, and is used to display the connection sequence from the first logic circuit to the Nth logic circuit, wherein N is a positive integer greater than or equal to 3, and M is a positive integer greater than or equal to 2 and less than or equal to N. The contact sequencing device provided by the present invention is capable of automatically and quickly sequencing the connection sequence of alarm contacts of a hydraulic high-voltage circuit breaker.
Description
technical field [0001] The invention relates to the technical field of automated testing, in particular to a junction sequencing device. Background technique [0002] A circuit breaker is a switch used to cut off the circuit, connect the load circuit and cut off the fault circuit. It can prevent accidents from expanding and ensure safe operation. Therefore, circuit breakers are widely used, especially in substations, where high-voltage circuit breakers are often used to ensure the safe operation of the substation. [0003] Among them, there are many forms of high-voltage circuit breakers, and the hydraulic form of high-voltage circuit breakers is the more commonly used one. For hydraulic form of high-voltage circuit breakers, only when a certain hydraulic pressure is met can the high-voltage circuit breaker work normally, so its own setting There are multiple alarm contacts with different pressures, such as the lock reclose connection point, the lock close connection point,...
