Summary of the invention
The objective of the invention is, a kind of machinery and the hybrid-type compensation arrangement of power electronics are provided when low for voltage is instantaneous.Can be used for the demanding user of the quality of power supply.
Technical scheme of the present invention is to adopt permanent magnet mechanism to cooperate the driving mechanism of making the high speed machine switch with repulsive force mechanism, drives the switch arc control device by it and forms the high speed machine switch.Device provides electric energy by mechanical switch for the user when operate as normal, voltage is low or when having a power failure when occurring, the quick disjunction of mechanical switch, and the current limiting characteristic that rely on power electronic device cooperate separate power supplies and start UPS and power for the user simultaneously.
A kind of electro-mechanical mixed voltage wink is hanged down compensation arrangement, and the output of commutating circuit links to each other with high efficiency UPS and constitutes series arrangement, and wherein the input of commutating circuit links to each other with power supply, the other end of high efficiency UPS with receive equipment after inversion system links to each other; This series circuit and speed-sensitive switch, current limliting are cut-off semiconductor and are constituted parallel-connection structure, and this parallel-connection structure links to each other with visual plant; Detecting judge module links to each other with high efficiency UPS; Electric energy is powered by speed-sensitive switch when operate as normal, in that voltage takes place is instantaneous when low, cooperates current limliting to cut-off semiconductor by speed-sensitive switch and comes split circuit, and come to be power devices by detecting judge module, high efficiency UPS, inversion system.
Speed-sensitive switch is linked to each other with permanent magnet mechanism by repulsive force mechanism, and the actuating of again by the insulation column formation that links to each other with arc control device, divide, closing a floodgate is carried out by repulsive force mechanism, realizes that by permanent magnet mechanism the position keeps; Buffer unit links to each other with permanent magnet mechanism, is used for preventing the spring of locking mechanism.
Current limliting is cut-off the series and parallel use that semiconductor is IGBT, GCR, GTO, MOSFET semiconductor device, use in parallel with speed-sensitive switch again; Separate trouble power conducting in advance constantly at needs, and after speed-sensitive switch cut-offs, end at once.
Arc control device adopt arc control device such as vacuum interrupter or employing air type arc control device.Buffer unit adopts buffer units such as spring buffer or employing hydraulic cushion.
Effect of the present invention and benefit are: adopt high speed machine formula switch to combine with power electronic device and realize the instantaneous low compensation of voltage, efficiently solve the power electronic device long-term work under big electric current and produce the infringement of heat that bigger power loss and loss produce, and make the functional reliability of device and discharge capacity obtain large increase for device.The high speed machine switch is simple in structure simultaneously, easy care.
