Abstract
A kind of slidingtype arc-control device of high pressure chopper switch, comprise and be fixed on the cutting knife on dwang and the fixed contact for accepting cutting knife, described cutting knife is arranged with an insulating case that can slide along it, insulating case is fixedly connected with a tooth bar extended back, the bearing of fixing dwang is also fixed with the gear with dwang concentric, the lower surface of described tooth bar is meshed with gear, make tooth bar in the process of rotating to the direction away from fixed contact with cutting knife, can be stirred by gear and promote insulating case along cutting knife and slide into its top, and in the process of rotating towards fixed contact with cutting knife, can be stirred by gear and pull insulating case to make it slide backward along cutting knife, thus the front end making cutting knife coordinate with fixed contact is exposed from insulating case.In cutting knife and fixed contact separation process, insulating case can promote reach by tooth bar, and position cutting knife being produced electric arc covers, thus makes electric arc cool rapidly and extinguish.
Description
Technical field
The utility model relates to a kind of high pressure chopper switch, specifically a kind of slidingtype arc-control device of high pressure chopper switch.
Background technology
When supply voltage exceedes tens of volt, drop-out current when tens of peace is above, be reduce the space of electric arc to the scaling loss of contact and the expansion of restriction electric arc, usually need the measure taking to strengthen arc extinguishing ability, for this reason and the device adopted is called arc-control device.And existing arc-control device or complex structure, high cost, or arc quenching effect is undesirable, cannot satisfy the demands.
Utility model content
Technical problem to be solved in the utility model be to provide a kind of can the high pressure chopper switch slidingtype arc-control device of fast arc extinction.
The utility model for solving the problems of the technologies described above adopted technical scheme is: a kind of slidingtype arc-control device of high pressure chopper switch, comprise and be fixed on the cutting knife on dwang and the fixed contact for accepting cutting knife, described cutting knife is arranged with an insulating case that can slide along it, insulating case is fixedly connected with a tooth bar extended back, the bearing of fixing dwang is also fixed with the gear with dwang concentric, the lower surface of described tooth bar is meshed with gear, make tooth bar in the process of rotating to the direction away from fixed contact with cutting knife, can be stirred by gear and promote insulating case along cutting knife and slide into its top, and in the process of rotating towards fixed contact with cutting knife, can be stirred by gear and pull insulating case to make it slide backward along cutting knife, thus the front end making cutting knife coordinate with fixed contact is exposed from insulating case.
The medial surface of the part of described insulating case between cutting knife and fixed contact, is provided with the slit extended along cutting knife length direction.
The beneficial effects of the utility model are: insulating case can in cutting knife motion process, by gear and tooth bar effect and move forward and backward, when cutting knife and fixed contact are closed a floodgate, its front end can be exposed.And in cutting knife and fixed contact separation process, insulating case can promote reach by tooth bar, position cutting knife being produced electric arc covers, thus makes electric arc cool rapidly and extinguish.Achieve fast arc extinction by this structure, and the parts relative cost increased is lower.

Embodiment
Structure of the present utility model composition and connected mode is illustrated below in conjunction with accompanying drawing.
A slidingtype arc-control device for high pressure chopper switch, comprises and is fixed on the cutting knife 2 on dwang 1 and the fixed contact 3 for accepting cutting knife, and dwang 1 is controlled to rotate by operating mechanism, thus drives cutting knife 2 to move, and realizes and the combined floodgate of fixed contact or separating brake.The concrete structure mode of operating mechanism can with reference to mode disclosed in prior art.The key point of the application is, described cutting knife is arranged with an insulating case 4 that can slide along it, and covering is wrapped up rapidly in the position by insulating case cutting knife being produced electric arc, thus realizes arc extinguishing.The material of insulating case 4 can adopt asbestos, pottery etc.The concrete methods of realizing of insulating case 4 motion mode can adopt following structure.Insulating case 4 is fixedly connected with a tooth bar extended back 5, the bearing of fixing dwang is also fixed with the gear 6 with dwang concentric, and the lower surface of described tooth bar is meshed with gear.Because gear 6 maintains static, and tooth bar 5 can with the axis rotation of cutting knife 2 around gear 6, and in rotation process, gear just can stir tooth bar, and then drive insulating case 4 to slide along cutting knife 2.According to data such as the rotational angles in the distance between cutting knife and fixed contact, divide-shut brake process, space width on the size of gear and wheel and rack is set, can make tooth bar in the process of rotating to the direction away from fixed contact with cutting knife, can be stirred by gear and promote insulating case along cutting knife and slide into its top, and in the process of rotating towards fixed contact with cutting knife, can be stirred by gear and pull insulating case to make it slide backward along cutting knife, thus the front end that cutting knife is coordinated with fixed contact be exposed from insulating case.
The medial surface of the part of described insulating case 4 between cutting knife 2 and fixed contact 3, is provided with the slit 8 extended along cutting knife length direction.The effect of this structure is, after the position that cutting knife 2 front end is produced electric arc by insulating case 4 covers, forces the electric arc flowed out from insulating case front end to enter slit and accelerating cooling and extinguishing.
Claims (2)
1. the slidingtype arc-control device of a high pressure chopper switch, comprise and be fixed on the cutting knife (2) on dwang (1) and the fixed contact (3) for accepting cutting knife, it is characterized in that: on described cutting knife, be arranged with an insulating case (4) that can slide along it, insulating case (4) is fixedly connected with a tooth bar extended back (5), the bearing of fixing dwang is also fixed with and the gear of dwang concentric (6), the lower surface of described tooth bar is meshed with gear, make tooth bar in the process of rotating to the direction away from fixed contact with cutting knife, can be stirred by gear and promote insulating case along cutting knife and slide into its top, and in the process of rotating towards fixed contact with cutting knife, can be stirred by gear and pull insulating case to make it slide backward along cutting knife, thus the front end making cutting knife coordinate with fixed contact is exposed from insulating case.
2. the slidingtype arc-control device of a kind of high pressure chopper switch as claimed in claim 1, is characterized in that: described insulating case (4) is positioned at the medial surface of the part between cutting knife (2) and fixed contact (3), is provided with the slit (8) extended along cutting knife length direction.
