Abstract
The invention provides a multi-breakpoint circuit breaker. A preset connection mode is adopted, at least a pair of fixed contacts are arranged in a base, at least two sets of fixed contacts corresponding to two sets of movable contacts opposite to the flow direction of current are arranged on the pair of the static contacts, and one set of fixed contacts correspond to one arc extinguishing chamber, a plurality of breakpoints are connected in series in the base of the circuit breaker, so that users do not need to wire outside a wiring terminal for connecting the breakpoints in series. Long time-delay characteristics are also set in the preset wiring mode, so that the motion characteristics of the multi-breakpoint circuit breaker cannot be affected when the multi-breakpoint circuit breaker is used by the users.
Description
Technical field
The present invention relates to breaker of plastic casing, belong to Low Voltage Electrical Apparatus.
Background technology
Along with the development of new energy technology, low voltage component is had higher requirement.Especially along with the development of photovoltaic power plant grows, the performance index of the protection component needed for power plant there has also been higher requirement.In photo-voltaic power supply direct current system, the rated operational voltage of low-voltage electrical apparatus is even up to DC1500V.Adopt the method for breakpoint series connection, the interrupting performance of circuit breaker can be improved.To this, domestic and international many producers have also launched respectively various breaker connection application scheme, carry out wiring at the external wiring terminal place of circuit breaker, and pole, the two poles of the earth making circuit breaker or more is together in series to form series-break.Although this application scheme can reach the requirement of high working voltage, but the length 2m that often wiring at engineer applied middle connecting terminal place can not specify according to 8.3.3.3.4 in GB 14048.2 implements, heat accumulation is herein caused to increase like this, heat is after circuit breaker internal, and directly impact adopts bimetal leaf as the long delay operating characteristics of long delay release.
Summary of the invention
The present invention proposes a kind of multibreak circuit breaker, adopt preset connected mode, Shell of circuit breaker inside multiple breakpoint is connected, need not user in order to series-break is voluntarily in the wiring of binding post place.Long delay characteristic is also adjust under the mode of this preset wiring, and when user uses, its operating characteristics also can not be affected.
The present invention is by the following technical solutions:
A kind of multibreak circuit breaker, comprises pedestal, moving contact, arc control device, wherein:
At least one is placed on the twin fixed contact in pedestal has two groups of fixed contacts;
Two groups of moving contacts that these two groups of fixed contacts are contrary with current direction are respectively corresponding;
One group of corresponding arc control device of fixed contact.
Further:
Two groups of fixed contacts on described twin fixed contact lay respectively in two adjacent chambers of pedestal, and insulation wall between two chambeies has groove.
Described twin fixed contact is made up of solder contacts on the conducting base of one, or is made up of solder contacts on the conducting base combined.
Groove on described insulation wall is between two fixed contacts of twin fixed contact or above two fixed contacts.
The present invention adopts preset connected mode, Shell of circuit breaker inside multiple breakpoint is connected, need not user in order to series-break is voluntarily in the wiring of binding post place.Long delay characteristic is also adjust under the mode of this preset wiring, and when user uses, its operating characteristics also can not be affected.
