Abstract
The utility model relates to a minisize circuit breaker with a remote breaking function, which mainly solves the technical problem that the existing minisize circuit breaker is not provided with the remote breaking function. The minisize circuit breaker is characterized in that a coil of the circuit breaker is a shunt trip coil; and a lead-in wire and a lead-out wire of the shunt trip coil are connected with a load terminal of an N-pole body connected with a zero wire and a phase line of a remote control system respectively. The minisize circuit breaker has the benefits that the coil in the original circuit breaker adopts the shunt trip coil and the lead-in wire and the lead-out wire of the shunt trip coil are connected with the load terminal in the N-pole body connected with the zero wire and the phase wire of the remote control system; therefore, when the breaking of the circuit needs to be controlled, a rated voltage signal is input to the shunt trip coil through the wire by the remote control system so that the shunt trip coil is electrified and generates the magnetic field, thus driving a top rod to impact an operation mechanism so that a movable contact is separated from the static contact; and the operation mechanism drives the operation mechanism of the L-pole body to synchronously link to trip simultaneously, thus realizing remote breaking of circuit breaker.
Description
Technical field
The utility model relates to a kind of circuit breaker, relates to a kind of miniature circuit breaker with long-range disjunction function in particular, is mainly used in the low-voltage electrical apparatus field.
Background technology
Miniature circuit breaker is mainly used in the disjunction of control illuminating line, the type of miniature circuit breaker mainly includes 1P, 1P+N, 2P etc., wherein the 1P+N circuit breaker mainly includes L utmost point body that connects phase line and the N utmost point body that connects zero line, L utmost point body has overload, short-circuit protection function, when overload or short circuit take place in phase line, the tripping coil of the extremely intrinsic electromagnetic system of L produces the field drives push rod makes moving contact separate with fixed contact, realizes the disjunction of circuit; And N utmost point body is not with defencive function, only connects synchronously and the disjunction circuit with L utmost point body; Though the interrupting performance of the circuit breaker of 1P+N is more reliable than 1P circuit breaker, but can't carry out Long-distance Control to circuit, such as can't carry out long-range disjunction to the street lamp between the building, and can only pass through artificial separating brake, so not only increase administrative staff's workload and can not satisfy the demand of urban modernization.
Summary of the invention
Do not have technical problems such as long-range disjunction function in order to solve existing miniature circuit breaker; The utility model provides a kind of miniature circuit breaker with long-range disjunction function, and this circuit breaker not only has overload, short-circuit protection function and also can long-range disjunction function.
For solving above technical problem, the technical scheme that the utility model is taked is a kind of miniature circuit breaker with long-range disjunction function, its L utmost point body that includes the disjunction of control phase line reaches the N utmost point body that is used to control the zero line disjunction with the synchronous interaction of L utmost point body, described N utmost point body includes housing and is installed in the interior electromagnetic system of housing, and this electromagnetic system includes support, static iron core, moving iron core, push rod, back-moving spring, sleeve and coil; It is characterized in that described coil is a shunt opening trip coil, being connected with the N utmost point body load end that is connected zero line and the phase line of tele-control system respectively of this shunt opening trip coil into and out of lead.
The beneficial effects of the utility model are that the coil in original circuit breaker is changed into shunt opening trip coil and advancing shunt opening trip coil, going out lead is connected with the phase line of extremely intrinsic load end of the N that is connected zero line and tele-control system, like this when needing the disjunction of control circuit, as long as import a nominal voltage signal through lead to shunt opening trip coil by tele-control system, make the shunt opening trip coil energising produce magnetic field, thereby driving push rod bump operating mechanism makes moving contact separate with fixed contact, and operating mechanism drives the operating mechanism synchronous interaction separating brake of L utmost point body simultaneously, thereby realizes the long-range disjunction of circuit breaker.

Embodiment
Below in conjunction with accompanying drawing the utility model execution mode is described further:
Extremely shown in Figure 2 as Fig. 1, the utility model is a kind of miniature circuit breaker with long-range disjunction function, its L utmost point body 1 that includes the disjunction of control phase line reaches the N utmost point body 2 that is used to control the zero line disjunction with 1 synchronous interaction of L utmost point body, described N utmost point body 2 includes housing 3 and is installed in electromagnetic system 4 in the housing 3, and this electromagnetic system 4 includes support 41, static iron core 42, moving iron core 43, push rod 44, back-moving spring 45, sleeve 46 and coil 47; It is characterized in that described coil 47 is shunt opening trip coil, being connected with N utmost point body 2 load ends that are connected zero line and the phase line of tele-control system respectively of this shunt opening trip coil into and out of lead 471,472; Coil in original circuit breaker is changed into shunt opening trip coil and advancing shunt opening trip coil, go out lead 471,472 with N utmost point body 2 in zero line and the phase line of tele-control system be connected, like this when needing the disjunction of control circuit, as long as import a nominal voltage signal through lead 472 to shunt opening trip coil by tele-control system, make the shunt opening trip coil energising produce magnetic field, thereby driving push rod 44 bump operating mechanisms 5 makes moving contact 51 separate with fixed contact 52, and operating mechanism 5 drives the operating mechanism synchronous interaction separating brake of L utmost point body 1 simultaneously, thereby realizes the long-range disjunction of circuit breaker.
The foregoing description should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.
