Abstract
The utility model discloses a circuit breaker with a handcart. The circuit breaker comprises the handcart, wherein two vertical columns are fixed on two sides of the upper part of the handcart; a plurality of installation holes are symmetrically formed in each vertical column from top to bottom; two transverse beams are fixed with the two vertical columns by using a plurality of installation holes; three insulators are fixed on each transverse beam at intervals; the insulators which are arranged in vertical direction are opposite to each other; a conductive column is fixed on each insulator; the conductive columns which are opposite vertically are connected with each other through a conductive plate; an insulating sheath can be arranged at the rear end of each conductive column; and an elastic connecting head can be arranged at the front end of each conductive column. The circuit breaker with the handcart is simple in structure and low in manufacturing cost and can be matched with various switch cabinets.
Description
Technical field
The utility model relates to breaker technical field, especially a kind of circuit breaker with handcart.
Background technology
In breaker technical field; The existing circuit breaker great majority that match with handcart are vacuum circuit-breakers, because vacuum circuit-breaker needs supporting vacuum interrupter, pole and baroque operating mechanism, so manufacturing cost is higher; When vacuum circuit-breaker and switch cubicle match simultaneously; Generally require switch cubicle to adapt to the dimensional requirement of vacuum circuit-breaker, make the design of switch cubicle be restricted like this, it is not very suitable that the lower switch cubicle of some working voltages is selected for use vacuum circuit-breaker.
The utility model content
The technical problem that the utility model will solve provides a kind of circuit breaker with handcart, and is simple in structure, and low cost of manufacture can match with multiple switch cubicle.
For achieving the above object, the technical scheme of the utility model is: a kind of circuit breaker with handcart comprises handcart; Two columns are fixed in the both sides, top of handcart, and two columns are symmetrily processed with a plurality of installing holes from top to bottom, and two crossbeams utilize described a plurality of installing hole and two columns to fix; Three insulators of each fixed interval on two crossbeams; It is corresponding each other to be in insulator position up and down, is fixed with conductive pole on each insulator, and corresponding up and down conductive pole is connected through conductive plate again.
Further, the rear end of said each conductive pole is provided with insulating sleeve.
Further, the front end of said each conductive pole is provided with the degree of tightness connector.
Further again, the rear portion of described two crossbeams also is provided with protective plate.
Further again, the both sides of said handcart respectively are provided with two rollers.
The utility model cooperate handcart move again through conductive pole up and down with is connected about the conductive plate of conductive pole make the end of incoming cables in the switch cubicle and leading-out terminal interconnects or isolation each other; Save baroque operating mechanism in the vacuum circuit-breaker; Structure is comparatively simple; The part that constitutes is also less, so manufacturing cost is lower.
On the other hand, can change the upper-lower position of two crossbeams, cooperate link that the conductive plate of different length can make conductive pole up and down again, can match with multiple switch cubicle, and widen the scope of design of switch cubicle apart from change through a plurality of installing holes of two columns.
Description of drawings
Fig. 1 is the utility model top perspective view;
Fig. 2 is the utility model face upwarding stereogram;
Fig. 3 is that the A of Fig. 1 is to view.
Embodiment
Below in conjunction with accompanying drawing and concrete execution mode the utility model is done further explain.
Fig. 1 is to shown in Figure 3; A kind of circuit breaker with handcart comprises handcart 10, and two columns 1,2 are fixed in the both sides, top of handcart 10; Two columns 1,2 are symmetrily processed with a plurality of installing holes 3 from top to bottom; Two crossbeams 4,5 utilize described a plurality of installing hole 3 and two columns 1,2 to fix, three insulators 6 of each fixed interval on two crossbeams 4,5, and it is corresponding each other to be in insulator 6 positions up and down; Be fixed with conductive pole 7 on each insulator 6, corresponding up and down conductive pole 7 is connected through conductive plate 8 again.
The rear end of each conductive pole 7 is provided with insulating sleeve 71.
The front end of each conductive pole 7 is provided with degree of tightness connector 72.
The rear portion of two crossbeams 4,5 also is provided with protective plate 9.
The both sides of said handcart 10 respectively are provided with two rollers 101.
The utility model can change the upper-lower position of two crossbeams 4,5 through a plurality of installing holes 3 on two columns 1,2, cooperates link that the conductive plate 8 of different length can make conductive pole 7 up and down apart from change again, adapts to the switch cubicle of different size.
Below only be preferred embodiment of the utility model, the change that those skilled in the art does to be equal to by claim all falls into the protection range of this case.
Claims (5)
