Description
Technical Field
[0001] The present invention belongs to the technical field of lock tripping mechanisms, and particularly relates to a control system for a high-speed electromagnetic repulsion mechanism. Background Art
[0002] The electromagnetic repulsion mechanism is a new type of high-speed contact driving mechanism based on the principle of electromagnetic induction eddy current. Compared with traditional spring operating mechanisms, emerging permanent magnet mechanisms, and electromagnetic mechanisms, it has the advantages of simple structural principle, short mechanical delay time, and fast initial movement speed.
[0003] The hybrid type current-limiting circuit breaker composed of a high-speed electromagnetic repulsion contact mechanism and a power semiconductor in parallel has the advantages of large current-carrying capacity, fast turn-off speed, and strong current-limiting ability, and is a main development direction of new type current-limiting circuit breakers. In the hybrid type current-limiting circuit breaker, in order to limit and interrupt short-circuit current with a high rate of rise, it is required to have a high reaction speed and operating speed, and be able to cut off the fault circuit at the initial stage of the short-circuit fault. Since the operating speed of the power semiconductor device is extremely fast, the reaction speed of the mechanical contact mechanism has become a bottleneck restricting the performance of the current-limiting circuit breaker. At the same time, when the current-limiting circuit breaker cuts off the short-circuit current, an instantaneous overvoltage much larger than the system voltage will appear at both ends of the contact, so it is required that the mechanical contact can obtain the largest possible initial speed to form an insulating gap as early as possible.
[0004] Since the electromagnetic repulsion mechanism only provides an instantaneous impact force to drive the switch contact to separate at high speed, it is necessary to be equipped with a locking and tripping mechanism to meet the requirements of opening and closing the mechanical contact. However, there are still various problems in various lock hole control systems on the market.
[0005] For example, a hybrid integrated high-potential energy supply system for a high-voltage DC circuit breaker disclosed in the authorized announcement number CN106487043A, although the technical solution provided realizes the electrical isolation condition at different potentials at high potential, can supply energy to the mechanical switch and power electronic devices at the same time, effectively reduces the device volume, has a simple structure, comprehensive functions, adopts high-frequency technology and optoelectronic technology, has simple control and reliable operation, but does not solve the problems existing in the existing lock hole control system that cannot effectively control and adjust, and realize a mechanical lock hole to facilitate detecting data information, etc. For this reason, we propose a control system for a high-speed electromagnetic repulsion mechanism.
