The invention discloses an intelligent low-voltage vacuum circuit breaker which comprises a casing, an insulating sleeve and a vacuum tube. An insulating pull rod is connected under the vacuum tube, an intelligent controller, an under-voltage electromagnetic switch, a flexible current transformer and a spring operating mechanism are arranged on the casing, and the under-voltage electromagnetic switch and the flexible current transformer are arranged between the intelligent controller and the spring operating mechanism. The spring operating mechanism is connected with the insulating pull rod. By means of he mode, the intelligent low-voltage vacuum circuit breaker can achieve complete zero flashover and is compact in structure, high in reliability, short in overall break time and good in compatibility.
Description
Technical field
The present invention relates to the low-voltage circuit breaker field, particularly relate 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 big short circuit current of appearance passes through; the phenomenon of being ostracised appears in main contact, also is subjected to the constraint of environmental conditions such as high height above sea level, low pressure, salt fog, vibrations simultaneously.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of intelligent type low-voltage vacuum circuit-breaker, can realize zero arcing fully, product with compact structure, reliability height, full break-time weak point.
For solving the problems of the technologies described above, the technical scheme that the present invention 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 instrument transformer and spring operating mechanism, and described under-voltage electromagnetic switch and flexible current instrument transformer 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, on the described insulating cylinder copper bus-bar is arranged fixedly.
The invention has the beneficial effects as follows: the present invention can realize zero arcing fully, and product with compact structure, reliability height, full break-time weak point are compatible good, can prevent the circuit breaker that closes a floodgate under the situation that secondary power supply does not apply.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of intelligent type low-voltage vacuum circuit-breaker of the present invention;
