Abstract
The invention discloses a series connection bar and a direct-current breaker with the same. Regular grooves are punched at the front and back surfaces of a traditional flat plate type structure of the series connection bar, and when the product is switched on, the current is accumulated on the surface of the connection bar due to a skin effect. Through densely punching regular grooves in the surface of the connection bar, the surface cooling area is increased, the connection bar surface temperature increase is lowered, and the product performance is improved.
Description
Technical field
The present invention relates to DC circuit breaker field, be specifically related to a kind of coupled in series row and include the DC circuit breaker that coupled in series is arranged.
Background technology
While work under high working voltage, existing DC circuit breaker adopts the mode of connection of multibreak series connection conventionally, to improve the interrupting performance of DC circuit breaker.While work under high working voltage, DC circuit breaker comprises multiple switching units, and user is connected in series multiple switching units to obtain the DC circuit breaker of expectation.Conventionally user uses cable to be connected in series multiple switching units.In prior art, there is the application scheme of various DC circuit breaker wiring, carried out wiring at the external wiring terminal place of multiple switching units of DC circuit breaker, made multiple switching units of DC circuit breaker be together in series to form series connection breakpoint.But because DC circuit breaker use occasion ambient temperature is high, poor radiation, is often directed at coupled in series row surface temperature too high, uses and brings electrical safety shadow to suffer to product.In CN203339078U, disclose a kind of DC circuit breaker that connects row that has, it is provided with aluminum or fin made of copper on connection row, although this structure is conducive to piece surface heat radiation, but its complex structure, be difficult to processing, cause processing difficulties, manufacturing cost is too high uneconomical.
Summary of the invention
In order to solve the deficiencies in the prior art, the one that provides of the present invention is with being beneficial to heat radiation, and coupled in series row's DC circuit breaker is arranged and included to economical and practical coupled in series again.
The technical solution that the present invention adopts is:
A coupled in series row, comprises and connects row's body, and described connection row body is provided with mounting groove, and described mounting groove both sides are provided with installing hole, and described connection row body tow sides are equipped with several radiating grooves.
Described coupled in series row, described coupled in series row is integral type structure.
Described coupled in series row, described radiating groove is cone tank, circular recess or square groove.
A kind of DC circuit breaker that includes coupled in series row, comprise housing, in described housing, be provided with several switching units, in several described switching units, at least two adjacent switching units use coupled in series as claimed in claim 1 to come outside series connection to be fixedly connected with.
The described DC circuit breaker that includes coupled in series row, is also provided with screw on described DC circuit breaker, the mounting groove on described coupled in series row is connected on housing, and described screw is fixedly mounted on housing through the installing hole of mounting groove both sides.
The described DC circuit breaker that includes coupled in series row, the described screw that is fixedly connected as connects, rivets or welding.
The invention has the beneficial effects as follows: the invention provides a kind of coupled in series row and include the DC circuit breaker that coupled in series is arranged, arrange positive and negative two punching rule of traditional plate armature groove in coupled in series, product in making current situation due to poly-skin effect, electric current is all gathered in and connects on row surface, by the distich surface punching rule groove that gathers that runs in, increase surface radiating area, reduce and connect row's surface temperature rise, enhance product performance.
