Description
Technical field
The utility model relates to low-voltage distribution field, the auxiliary body particularly on a kind of circuit breaker.
Background technology
In low-voltage circuit complete set of equipments power distribution cabinet, usually need multiple stage breaker of plastic casing is installed side by side.Current breaker of plastic casing is substantially all fixedly mounted on the crossbeam of power distribution cabinet, and this manually holes according to the installation dimension of circuit breaker with regard to needing on crossbeam, installs comparatively inconvenience.In addition, after equipment runs, sometimes the quantity of the demand increase and decrease circuit breaker according to client is needed, this will re-move and adjust the position of installing circuit breaker, due to the crossbeam of power distribution cabinet being installed with more low voltage electrical equipment, and each electric equipment is in position, wiring is complicated, therefore operates and bothers very much.
Utility model content
The utility model, for the deficiencies in the prior art, provides a kind of easy for installation and be convenient to adjust the breaker of plastic casing installing mechanism of circuit breaker installation site.
For solving the problems of the technologies described above, technical solution adopted in the utility model is as follows:
A kind of breaker of plastic casing guide rail fixing structure, comprise guide rail equipped mutually and fixed head, breaker of plastic casing is arranged on fixed head, and fixing board card is contained on guide rail, and guide rails assembling is in power distribution cabinet; Described guide rail is strip, and the lower edge place of guide rail has been horizontally disposed with location-plate; Described fixed head is provided with earthing screw hole, fixing circuit breaker screw hole and the hook for fixed head being mounted on guide rail upper edge, the lower edge of fixed head is also provided with and the latch segment that match parallel with guide rail location-plate, and fixed head is fixedly mounted on guide rail by the lock-screw of cross-under on latch segment.
Improvement of the present utility model is: the middle part of described fixed head is provided with radiator window.
Further improvement of the utility model is: described guide rail is dull and stereotyped rectangle structure, and the middle part of guide rail offers the strip louvre of corresponding fixed head radiator window.
Improvement of the present utility model is also: on described guide rail, the both sides up and down of louvre are provided with some lightening holes.
The utility model structure is simple, with low cost, adopt the structure that guide rail is equipped with mutually with fixed head, make the installation of circuit breaker become extremely easy, and to increase and decrease in the future circuit breaker quantity, movement and adjustment circuit breaker installation site time, operate also more for convenience.Application of the present utility model, also for the maintenance of circuit breaker in low voltage complete set running provides conveniently, when circuit breakers need maintenance, dismounting and replacing time, as long as unclamp trip bolt, circuit breaker can easily unload.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is rearview of the present utility model.
In figure, each label is: 1. guide rail, 11. lightening holes, 12. louvres, 13. location-plates, 2. fixed head, 21. hold-down screws, 22. hooks, 23. lock-screws, 24. latch segments, 25. earthing screw holes, 26. radiator windows, 27. trays.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is further elaborated.
As depicted in figs. 1 and 2, comprise guide rail 1 equipped mutually and fixed head 2, breaker of plastic casing is arranged on fixed head structure of the present utility model, and fixing board card is contained on guide rail, and guide rails assembling is in power distribution cabinet.
In the present embodiment, guide rail 1 is dull and stereotyped rectangle structure, and the lower edge place of guide rail 1 has been horizontally disposed with location-plate 13, and the middle part of guide rail offers strip louvre 12, and the both sides up and down of louvre are provided with some lightening holes 11, as shown in Figure 2.
Fixed head 2 is provided with earthing screw hole 25, fixing circuit breaker screw hole, hook 22, latch segment 24 and radiator window 26.Earthing screw hole 25 is arranged on the top of fixed head, for installing earthing screw, the ground wire of circuit breaker can be made to be connected with power distribution cabinet housing after earthing screw is drawn, ensure the shell reliable ground of circuit breaker.Screw hole is used for fixing circuit breaker use, is at least provided with two, and when being set to two, two screw holes diagonally opposing corner on fixed head is arranged, for equipped hold-down screw 21, to ensure circuit breaker to be securely fixed on fixed head.Hook is used for fixed head to be mounted on guide rail upper edge; Be provided with two hooks in the present embodiment, two hooks are horizontally disposed with.Latch segment 24 is arranged on the lower edge of fixed head 2, and latch segment 24 is parallel with the location-plate 13 of guide rail and match, and latch segment 24 is for through lock-screw 23, and lock-screw is connected with nut, and nut is positioned at the below of latch segment; After circuit breaker position is adjusted, by screwing lock-screw, making lock-screw be pressed on the location-plate of guide rail, fixed head can be fixedly mounted on guide rail, as shown in Figure 2.Radiator window 26 is arranged on the middle part of fixed head, and radiator window 26 is corresponding to the louvre position on guide rail, facilitates circuit breaker to dispel the heat.
In the present embodiment, fixed head is also provided with tray 27, tray is arranged on the below of hook, and the distance between tray to hook is corresponding with the height of guide rail, and the setting of tray is for alleviating the bearing capacity of hook.
When the utility model is installed, guide rail is fixed in distribution cabinet, circuit breaker is installed to (circuit breaker of different cage uses different fixed head) on fixed head, then the circuit breaker with fixed head is mounted on guide rail, circuit breaker along guide rail movement arbitrarily in the horizontal direction, can be fixed with lock-screw when correct position.
The utility model be applicable to BKM series 63 to 160 cage all types (pyromagnetic, electric leakage, intelligence, electricity behaviour etc.) breaker of plastic casing, and domestic and international all same industries produce same cage, the maintenance in the installation and operation of breaker of plastic casing of the same type in low-voltage complete switch equipment, replacing, be particularly useful for installing with miniature circuit breaker in distribution system simultaneously, convenient especially.
