Abstract
The utility model discloses an intelligent type low voltage vacuum circuit breaker comprising a machine shell, insulation cylinders and a vacuum tube, wherein an insulation pull rod is connected below the vacuum tube. The machine shell is provided with an intelligent controller, an under-voltage electromagnetic switch, a flexible current transformer and a spring operation mechanism, wherein the under-voltage electromagnetic switch and the flexible current transformer are arranged between the intelligent controller and the spring operation mechanism, and the spring operation mechanism is connected with the insulation pull rod. Through the above mode, the intelligent type low voltage vacuum circuit breaker can be completely free from flashover and is advantaged by compact product structure, high reliability, short full break time, and good compatibility.
Description
Technical field
The utility model relates to the low-voltage circuit breaker field, particularly relates to a kind of intelligent type low-voltage vacuum circuit-breaker.
Background technology
Low-voltage circuit breaker is as a kind of low-voltage electrical apparatus; be widely used in the distribution network; play the effect of overload, short circuit and the under-voltage protection of circuit and power-supply device; it is air circuit blow-out mode that existing low-voltage circuit breaker adopted more; because the contact arc-extinguishing structure of air circuit is the compensation main contact that main contact adopts the multi-channel parallel mode; when the larger short circuit current of appearance passes through; the phenomenon of being ostracised appears in main contact, also is subject to simultaneously the constraint of the environmental conditions such as high height above sea level, low pressure, salt fog, vibrations.
The utility model content
The technical problem that the utility model mainly solves provides a kind of intelligent type low-voltage vacuum circuit-breaker, can realize fully zero arcing, and product with compact structure, high, the full break-time of reliability are short.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of intelligent type low-voltage vacuum circuit-breaker is provided, comprise casing, insulating cylinder and vacuum tube, be connected with insulated tension pole under the vacuum tube, described casing is provided with intelligent controller, under-voltage electromagnetic switch, flexible current mutual inductor and spring operating mechanism, and described under-voltage electromagnetic switch and flexible current mutual inductor are arranged between intelligent controller and the spring operating mechanism; Described spring operating mechanism is connected with described insulated tension pole.
Preferably, described spring operating mechanism comprises spring mechanism and geared linkage mechanism, and described geared linkage mechanism and described insulated tension pole bottom are fixed.
Preferably, also be provided with combined floodgate electromagnetic switch and separating brake electromagnetic switch between described intelligent controller and the spring operating mechanism.
Preferably, be fixed with copper bus-bar on the described insulating cylinder.
The beneficial effects of the utility model are: the utility model can be realized fully zero arcing, and product with compact structure, high, the full break-time of reliability are short, compatible good, can prevent in the situation that secondary power supply does not apply the circuit breaker that closes a floodgate.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model intelligent type low-voltage vacuum circuit-breaker;
