Abstract
The invention discloses a top cover of a pulling frame for a circuit breaker, which comprises a top cover body arranged on the pulling frame. The top cover body is positioned above an arc extinguish chamber of the circuit breaker; and a plurality of insulating separators are arranged on the top cover body in a detachable mode. The top cover of the pulling frame for the circuit breaker has simple structure and is easy to implement; by arranging the insulating separators on the top cover body of the pulling frame, the top cover has a strong arc separation function and is safe and reliable; and the insulating separators are clamped with the top cover body, so that the top cover is convenient to install, is convenient to replace and is economic and practical.
Description
Technical field
The present invention relates to a kind of top cover, relate in particular to a kind of circuit breaker with the top cover of taking out frame.
Background technology
Withdrawable circuit breaker can be divided into two relatively independent parts, promptly breaker body with take out frame.Breaker body has connection, test and separates three different positions in taking out frame.At present, existing withdrawable circuit breaker, its top cover of taking out frame are arranged at a plurality of arc control device top of breaker body; And a chamber is arranged between a plurality of arc control device; When circuit breaker breaks off moment, the electric arc ejection in a plurality of arc control device is in the chamber above the top cover of taking out frame and a plurality of arc control device; Yet its whole chamber connects, and has certain potential safety hazard.
Summary of the invention
The objective of the invention is to the problems referred to above, provide a kind of circuit breaker with the top cover of taking out frame, it has simple in structure, is easy to realize, and is easy for installation, the arc good effectiveness.
The objective of the invention is to realize through following technical scheme:
A kind of circuit breaker comprises being arranged at the top cover body of taking out on the frame that said top cover body is positioned at the arc control device top of circuit breaker, dismountable polylith insulating barrier that is provided with on it with the top cover of taking out frame.
Further, said top cover body is provided with two insulating barriers.
Further, said insulating barrier is processed by the BMC material.
Further, have draw-in groove on the said top cover body, the side that said draw-in groove is positioned at arc control device is provided with opening, and draw-in groove matches with fixture block on the insulating barrier.
Further, said fixture block and insulating barrier are structure as a whole.
Beneficial effect of the present invention does, said circuit breaker is simple with the cap structure of taking out frame, is easy to realize, it is through being provided with insulating barrier taking out on the top cover body of frame; Have very strong arc function, safe and reliable, and insulating barrier engages with the top cover body; Be convenient to install, replacement is convenient, and is economical and practical.
Description of drawings
Fig. 1 is the structural representation of circuit breaker of the present invention with the top cover of taking out frame;
Fig. 2 is the installation site sketch map of circuit breaker of the present invention with the top cover of taking out frame.
Among the figure:
1, top cover body; 2, insulating barrier; 3, fixture block; 4, arc control device.
Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and through embodiment.
Please with reference to Fig. 1 and shown in Figure 2, Fig. 1 is the structural representation of circuit breaker of the present invention with the top cover of taking out frame; Fig. 2 uses the top cover installation site sketch map of taking out frame for circuit breaker of the present invention.In present embodiment, a kind of circuit breaker comprises being arranged at the top cover body of taking out on the frame 1 with the top cover of taking out frame; Said top cover body 1 is positioned at arc control device 4 tops of circuit breaker, dismountablely on it is provided with two insulating barriers 2, and said insulating barrier 2 is processed by the BMC material; Have draw-in groove on the said top cover body 1; The side that said draw-in groove is positioned at arc control device 4 is provided with opening, and draw-in groove matches with fixture block 3 on the insulating barrier 2, and said fixture block 3 is structure as a whole with insulating barrier 2.
Though 1 is provided with two insulating barriers 2 on the top cover body of taking out frame shown in the drawings; But the invention is not restricted to this; The quantity of insulating barrier 2 is decided according to the quantity of arc control device 4, to reach the chamber of a plurality of arc control device 4 tops is separated, and plays the arc effect and gets final product.
Though the top cover body 1 of taking out frame shown in the drawings engages with insulating barrier 2; But the invention is not restricted to this; Insulating barrier 2 also can be installed in top cover body 1 through other modes; As long as be convenient to install, replacement is convenient, and can play the effect that the chamber of arc control device 4 tops is separated and get final product.
The present invention is simple in structure, is easy to realize, it has very strong arc function through insulating barrier 2 being set taking out on the top cover body 1 of frame, and is safe and reliable, and insulating barrier 2 engage with top cover body 1, is convenient to install, and replaces to make things convenient for, and is economical and practical.
Above embodiment has just set forth basic principle of the present invention and characteristic; The present invention is not limited by the foregoing description; Under the prerequisite that does not break away from spirit and scope of the invention, the present invention also has various variations and change, and these variations and change all fall in the scope of the invention that requires protection.The present invention requires protection range to be defined by appending claims and equivalent thereof.
