Abstract
The utility model discloses a compact leakage circuit breaker shell provided with a middle cover which is provided with an upper cover (1), a middle cover (2) and a base (3); the upper cover (1) is provided with a tool through hole (5), an indicator lamp hole (6) and a display window hole (7); the middle cover (2) is provided with a handle through hole (11), a motor mounting area and a transformer mounting area; the two ends of the base (3) are provided with an incoming post mounting hole and an outgoing post mounting hole (4); a static contact, a machine head and a mutual inductor mounting area are respectively arranged in the base; the motor mounting area on the middle cover (2) is provided with a motor semi-buried round hole (9) and a support ring (8); the transformer mounting area is provided with a transformer semi-buried square hole (10); screw holes (12) are arranged beside the round hole (9) and the square hole (10); a zero line slot (14) in the base (3) is arranged in the rightmost side; and three live wire slots (13) are arranged in the middle part and the left side of the base. The compact leakage circuit breaker shell is specially used for mounting electric-manual dual reclosing leakage circuit breakers, and has the advantages as follows: the height of the upper cover is lower; the matching area with a distribution box is broad; and the slot arrangement of the base after adjustment is beneficial for earning foreign exchange through export.
Description
Technical field
The utility model relates to a kind of residual current circuit breaker shell, is to be suitable for installing the residual current circuit breaker shell with automatic reclosing function.
Background technology
CN03202803.2 discloses a kind of residual current circuit breaker mounting box of electronic and dual-use manual, have loam cake, middle cover and base three-decker, on the end face of middle cover screw is arranged, with fixed electrical machinery, motor-operating mechanism and transformer, thereby make the clear height of loam cake must be greater than the highest parts setting height(from bottom) among above-mentioned motor, motor-operating mechanism and the transformer three, the insufficient height compactness of shell, can't with the narrow distribution box of some inner rooms coupling.In addition, domestic general three-phase and four-line residual current circuit breaker base, when inlet wire post, dynamic/static contact, arc control device place the top, the wire casing of zero line places the base Far Left, in the middle of the wire casing of three-phase firewire places and the right is arranged in the right of zero line wire casing one by one, and this arrangement is opposite with the mode of a plurality of countries in the world, versatility is poor, the influence foreign exchange earning.
The utility model content
At the above-mentioned deficiency of prior art, thereby the technical problem that the utility model need solve is to design the residual current circuit breaker shell that a kind of loam cake height wire casing that can suitably reduce, zero line places base rightmost and the compact band middle cover that some countries can be general in the world.
The technical scheme that solves the problems of the technologies described above is: the residual current circuit breaker shell of this compact band middle cover, be divided into loam cake, middle cover and base three parts, loam cake includes the manual brake separating through hole, status indicator lamp hole and demonstration fenestra, in cover and include the handle through hole, motor installing zone and transformer installing zone, there are inlet wire post installing hole and outlet column installing hole in the base two ends, also include the fixed contact installing zone in the base, head installing zone and instrument transformer installing zone, it is characterized in that the motor installing zone that covers in said has the motor that motor partly buries on circular hole and this circular hole periphery and holds up ring, said transformer installing zone has transformer and partly buries square hole, there are the supporting fastening motor and the screw of transformer in above-mentioned circular hole that partly buries and square hole side, zero line wire casing in the base places rightmost, and the middle and left side is three live wire wire casings arranging one by one.
The beneficial effects of the utility model are: the shell especially height of loam cake is relatively little, adaptive wide with distribution box, and the exchange of zero line wire casing and three-phase firewire wire casing position in the base has solved and the national versatility problem of part, helps foreign exchange earning.
Description of drawings
Fig. 1 is the utility model overall structure schematic diagram.
Fig. 2,3,4 is respectively loam cake of the present utility model, middle cover, understructure schematic diagram.
Embodiment
The utility model is described in detail below in conjunction with embodiment and with reference to accompanying drawing: with reference to Fig. 1, show that this shell overall structure is the class cuboid, refer again to Fig. 2,3,4, demonstrate the residual current circuit breaker shell of this compact band middle cover, be divided into loam cake 1, middle cover 2 and base 3 three parts, loam cake 1 includes manual brake separating through hole 5, status indicator lamp hole 6 and demonstration fenestra 7, include handle through hole 11 on the middle cover 2, motor installing zone and transformer installing zone, there are inlet wire post installing hole and outlet column installing hole 4 in base 3 two ends, also include the fixed contact installing zone in the base, head installing zone and instrument transformer installing zone, it is characterized in that motor installing zone on the said middle cover 2 has the motor that motor partly buries on circular hole 9 and this circular hole periphery and holds up ring 8, said transformer installing zone has transformer and partly buries square hole 10, there are the supporting fastening motor and the screw 12 of transformer in above-mentioned circular hole that partly buries 9 and square hole 10 sides, zero line wire casing 14 in the base 3 places rightmost, and the middle and left side is three live wire wire casings 13 arranging one by one.Motor in the middle cover partly buries the diameter of circular hole and motor holds up the internal diameter of ring 8 to equate, all than the big 0.5-1mm of motor diameter, transformer partly buries the shape of square hole 10 and shape and the size match that size also should partly be buried the position with transformer, during installation, motor and transformer are placed circular hole 9 and square hole 10 respectively, be screwed into screw 12 with screw motor and transformer are fastened on the end face of middle cover 2, be the state that partly buries, thereby reduced the height of loam cake 1, seemed compact.When the inlet wire of the base 3 of three-phase and four-line residual current circuit breaker in the upper end, outlet is during in the lower end, live wire wire casing 13 is opposite with the present general mode of China with the arrangement of zero line wire casing 14 in it, in brief, is the zero line groove right side, and is left in the live wire groove.
