Description
Technical field
The utility model relates to a kind of circuit breaker, especially relates to a kind of electronic type plastics case circuit breaker.
Background technology
Circuit breaker is the electric equipment for the overload of AC and DC circuit, short circuit or under voltage protection, when overload, short circuit, can make the electric current disjunction in moment, and protection circuit and power-supply device are not damaged.Chinese patent discloses a kind of short circuit current protector (Granted publication number: CN 201032621Y) of breaker of plastic casing, it comprises the instrument transformer of order connection successively, signal conditioning circuit, single-chip microcomputer and actuator, wherein said instrument transformer is connected with each phase signal of telecommunication of electrical network, in order to export the little current signal of corresponding each phase, signal conditioning circuit is in order to nurse one's health each little current signal, export a plurality of conditioned signal, breaker of plastic casing also comprises a simulation trip circuit, it comprises: a plurality of amplifying circuits, its input are connected with each conditioned signal of signal conditioning circuit correspondingly; One comparison circuit; has an input; one relatively holds and an output; input is connected with the output of a plurality of amplifying circuits; relatively end connects a reference signal; output is connected with actuator; the short circuit current protector of breaker of plastic casing also comprises a power supply; its input is connected with described signal conditioning circuit; its output is connected with single-chip microcomputer with actuator; the simulation trip circuit also comprises a plurality of isolated components; be located at respectively between the output and comparison circuit input of each amplifying circuit, isolated component is diode, and the voltage of reference signal is between 2.OV～2.5V.But the dropout of this circuit breaker is inconvenient with contacting of tripping, and moving contact transmission speed when touching fixed contact or disengagement fixed contact is unhappy, meets accident easily.
The utility model content
The utility model provides a kind of electronic type plastics case circuit breaker, it mainly is the inconvenience that contacts that solves dropout with the tripping of existing in prior technology circuit breaker, moving contact at the touching fixed contact or when throwing off fixed contact transmission speed unhappy, the technical problem that meets accident easily etc.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals:
Electronic type plastics case circuit breaker of the present utility model; comprise shell, described shell is that plastics are made, and is connected with input terminal and outlet terminal on the shell; input terminal is connected with fixed contact; fixed contact is provided with arc angle, and shell is connected with handle, is hinged with the plectrum that can be stirred by handle in the shell; plectrum connects release; release is connected with the moving contact that can contact with fixed contact, and moving contact connects outlet terminal by overload protection arrangement, is provided with arc control device in the shell.Input terminal and outlet terminal can be screwed to be moulded on the shell, can be sealed with sealing plug on the shell of input terminal, outlet terminal outer end.Automatically snap close is opened when overload protection arrangement can make electric current excessive, made the tripping return.
As preferably, described overload protection arrangement includes instrument transformer, and instrument transformer is connected with electronic trip unit by supporter, and electronic trip unit connects moving contact.When circuit is short-circuited electric current, even magnetic force is sent with static iron core in instrument transformer energising back, the armature of static iron core one side is held, make tripping thread off by electronic trip unit, finish and open circuit.
As preferably, the inboard of described input terminal, outlet terminal all is provided with flash barrier.Flash barrier can prevent that the spark that circuit breaker produces from spilling outside the shell when tripping.
Characteristics such as therefore, the dropout that the utlity model has circuit breaker is comparatively convenient with contacting of tripping, and moving contact transmission speed when touching fixed contact or disengagement fixed contact is very fast, is not easy to meet accident, and is simple and reasonable for structure.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model.
Parts, position and numbering among the figure: shell 1, input terminal 2, outlet terminal 3, fixed contact 4, arc angle 5, handle 6, plectrum 7, release 8, moving contact 9, flash barrier 10, arc control device 11, instrument transformer 12, supporter 13, electronic trip unit 14.
Embodiment
Below by embodiment, and by reference to the accompanying drawings, the technical solution of the utility model is described in further detail.
Embodiment: the electronic type plastics case circuit breaker that this is routine as Fig. 1, comprises shell 1; shell is that plastics are made; be connected with input terminal 2 and outlet terminal 3 on the shell, input terminal is connected with fixed contact 4, and fixed contact is provided with arc angle 5; shell is connected with handle 6; be hinged with the plectrum 7 that can be stirred by handle in the shell, plectrum connects release 8, and release is connected with the moving contact 9 that can contact with fixed contact; moving contact connects outlet terminal by overload protection arrangement, is provided with arc control device 11 in the shell.Overload protection arrangement includes instrument transformer 12, and instrument transformer is connected with electronic trip unit 14 by supporter 13, and electronic trip unit connects moving contact 9.The inboard of input terminal, outlet terminal all is provided with flash barrier 10.
During use, earlier handle 6 is down pulled, handle is stirred plectrum 7 and is moved downward, and the tripping on the plectrum is and snap close snaps together, and handle is upwards pulled again, and moving contact 9 contacts with fixed contact 4, input terminal 2 conductings.When circuit is short-circuited electric current when excessive, make static iron core produce magnetic force after instrument transformer 12 energisings, armature is held, armature is held the back by supporter 13, electronic trip unit 14, thereby snap close is opened, and tripping is threaded off, thus open-circuit line.
The above only is specific embodiment of the utility model, but architectural feature of the present utility model is not limited thereto, any those skilled in the art is in field of the present utility model, and the variation of doing or modification all are encompassed among the claim of the present utility model.
