Abstract

A low voltage multi-pole breaker with a double shield, each pole where With a single-pole circuit breaker unit (11) with a rectangular box with six sides (12) with two large faceted faces (15,16) made of cast plastic material and the contact (19,22,23) is assembled. To match the circuit breaker room (24) that is encapsulated in unit (11), multiple units (11) will be installed side Connect the inside of the formwork (10) to make a multi-pole electric cutter. It is set up as a rotating contact bridge (19), which will operate with two opposite fixed contact parts (22,23), which this contact bridge (19) will be supported by a section. Rotation bar (20) where the cross-section is suitable In the center of the box (12) it is inserted in between and Was directed laterally by the two large faces (15,16) of the box (12), while it could In limited horizontal motion parallel to these large faces (15,16), this rod section (20) of the adjacent units (11) is mechanically attached by the rods. Continue Two parallel bars (28) that protrude perpendicular to the aforementioned large surface (15,16) and pass through a small gap across the opposite opening in diameter (29) provided in the bar section. Two consecutive (20) connecting rods (28) are then connected to a crank (42) with arms opposite each other in the line. The two-arm diameter (43) and the operating mechanism (32) are fixed to the upper (14) section of the unit (11), consisting of two metal flanges (34) supporting the slip support (40). Of the crank (42) and of the lower resistance provoke the crank

Claims (8)

1.Low-voltage multi-pole electric cutters with double shielding Each terminal where With a single-pole circuit breaker unit (11) with a rectangular box with six sides (12) with two large faceted faces (15,16) made of cast plastic material and movable and fixed contact parts ( 19,22,23) are fitted to the circuit breaker room (24) that is encapsulated in unit (11). Several (11) units will be installed side by side. Connect the inside of the casting frame (10) to make a multi-pole electric cutter. The moving contact parts are classified as A rotating contact bridge (19), which is operated with two opposing fixed contacts (22,23) and is supported by a rotating rod section (20), which will form a cross section of Suitable in the center of the box (12) it is inserted in-between and laterally guided by the two large faces (15,16) of that box (12), while being able to move in horizontal motion. Where the limit will be parallel With these large faces (15,16), characterized by the presence of this rod section (20) of the adjacent units (11) mechanically joined by two parallel connecting rods. Bars (28), which will protrude perpendicular to Such a large surface (15,16) and passes through a small gap across the opposite cavity (29) arranged in the two consecutive bars (20). (28) is directed to a crank (42) with two opposite arms in diameter (43), two large front surfaces (15, 16), each containing two curved cutouts (30 ) For a passage with a gap And movement Of the two connecting rods (28) and the operating mechanism (32) are fixed to the top (14) of the unit (11), it consists of two metal flanges (34) supporting the section The crankcase (40) of the said (42) crank and the bottom connecting rod will activate the crank. 2. Electric cutters according to clause 1 have characteristics that such mechanisms (32) are limited in their Side by such two parallel flanges (34), the distances between them are correspondingly Between such large faces (15,16) of one (11) unipolar unit 3.Electric cutters according to clause 1 have a feature where the front face of the bar section (20) faces the large (15,16) face that is also provided to cover such curved cutouts (30). Small gaps to limit gas leaks through these cutouts to the outside of the box (12) and to achieve the box where the middle part is almost non-leaking. 4. Electric cutters according to Article 3 have features that between the front surface And the large surface (15,16), a self-supporting plate (46), was inserted into place that would be firmly fixed in the The rotation of the aforementioned bars (28) and where it covers the bore in a way that will form a sealed valve. That hole is when an excess pressure occurs in the box. 5. Electric cut-offs, according to any of the above claims, have a feature in which a pad (27) is inserted between adjacent single-pole (11) units. All of the single pole units (11) and pads (27) are connected by alignment bars (37), and they consist of curved cutouts (30) for passage of the connecting rods (28). 6.Electric cut-offs according to clause 5 have the characteristics in which the orientation bar (37) will pass without gaps throughout the cavity (38) provided in the flange (34) of the mechanism (32). 7. The electric mowers, according to either of the above claims, has a feature where the mechanism (32) consists of a hand-operated lever (31) and this mechanism is encased in such a frame (10) where Which consists of a cutout for a lever that will pass through 8. The electric cut-off, according to either of the above claims, has a feature where such rod sections (20) are made of insulating material with openings (33) for the contact bridge (19) to pass through the right. Install floats along the diameter of the section (20) as follows and the hole (29) for the two connecting rods (28) to pass at an angle from the center relative to the diameter. 9. In accordance with either of the above claims there is a feature where the crank (42) fits snugly on each side of the box (12) and the connecting rod (28) passes through the entire rod (20) section and the crank.
