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 the low-voltage electrical apparatus field.
Background technology
Along with the development of new energy technology, low voltage component is had higher requirement.Especially along with constantly the developing of photovoltaic power plant, the performance index of the protection component that power plant is required have also had higher requirement.In the photo-voltaic power supply direct current system, the rated operational voltage of low-voltage electrical apparatus even up to DC1500V.Adopt the method for breakpoint series connection, can improve the interrupting performance of circuit breaker.To this, domestic and international many producers have also launched respectively various breaker connection application schemes, carry out wiring at the external connection terminal place of circuit breaker, make the two poles of the earth of circuit breaker or more multi-stage series connection get up to form the series connection breakpoint.Though this application scheme can reach the requirement of high working voltage; But often the wiring at practical applications middle connecting terminal place can not implemented according to the length 2m of 8.3.3.3.4 regulation among the GB 14048.2; Cause the heat accumulation here to increase like this; Heat is behind circuit breaker inside, and directly the long delay operating characteristics of bimetal leaf as the long delay release adopted in influence.
Summary of the invention
The present invention proposes a kind of multibreak circuit breaker, adopt and to preset connected mode, a plurality of breakpoints are connected in Shell of circuit breaker inside, need not the user for the breakpoint of connecting voluntarily in the wiring of binding post place.The long delay characteristic also is under this mode that presets wiring, to adjust, and its operating characteristics can not be affected yet when the user used.
The present invention adopts following technical scheme:
A kind of multibreak circuit breaker comprises pedestal, moving contact, arc control device, wherein:
At least one places on the twin fixed contact in the pedestal has two groups of fixed contacts;
Two groups of moving contacts that these two groups of fixed contacts are opposite with current direction respectively are corresponding;
One group of corresponding arc control device of fixed contact.
Further:
Two groups of fixed contacts on the said twin fixed contact lay respectively in two adjacent chambers of pedestal, and have groove on the insulation wall between two chambeies.
Said 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 of combination.
Groove on the said insulation wall between two fixed contacts of twin fixed contact or two fixed contacts above.
The present invention adopts and to preset connected mode, in Shell of circuit breaker inside a plurality of breakpoints is connected, need not the user for the breakpoint of connecting voluntarily in the wiring of binding post place.The long delay characteristic also is under this mode that presets wiring, to adjust, and its operating characteristics can not be affected yet when the user used.
