Abstract
The utility model discloses a fuse installing structure used in a low voltage power distribution cabinet, comprising a fuse fusible core (1) and a fuse pedestal (2). The lower part of the fuse pedestal (1) is equipped with an L-shaped fuse clapboard (3), the fuse clapboard (3) is a polycarbonate plate, and the fuse pedestal (1) and the fuse clapboard (3) are fixed on a mounting bar together. According to the fuse installing structure used in the low voltage power distribution cabinet having the above special installing structure, the problem is solved effectively that when fuses are in single-phase short circuit, the fuse fusible core may affect the adjacent fuse sets because of arc discharge to thereby expand the accident range, and the safety protection problem caused by that the fuses are arranged to closely to plug the fuse fusible core is solved at the same time.
Description
Technical field
The utility model relates to low-voltage distribution cabinet, especially relates to a kind of low-voltage distribution cabinet and uses the fuse mounting structure.
Background technology
At present, in the low-voltage distribution the complete sets of equipment, can often use a kind of model in the low-voltage cabinet is the High Rupturing Capacity fuse of NT series, and that uses in the low-voltage capacitance cabinet is many especially.
Because the layout of fuse all is side by side to arrange installation in the low-voltage cabinet, the distance between the fuse is very near, and its fusible core arcing possibly have influence on adjacent fuse group during as if fuse generation single-phase short circuit, has enlarged the scope of accident; Simultaneously, if certain fuse has been broken, the charged for replacement fuse, hand is easy to run into adjacent fuse again in the time of operation, causes the danger of electric shock easily.
The utility model content
The utility model technical problem to be solved is to provide a kind of low-voltage distribution cabinet to use the fuse mounting structure to the problem that exists in the prior art; Its objective is that its fusible core arcing possibly influence adjacent fuse group when reducing owing to the fuse single-phase short circuit; The risk of the scope of expansion accident then; Solve because fuse is near owing to installing the problem of the security protection that brings during the plug fusible core simultaneously.
The technical scheme of the utility model is that this kind low-voltage distribution cabinet is used the fuse mounting structure, comprises fuse fusible core and fuse base, and the below of described fuse base is provided with the fuse dividing plate, and fuse base is fixed on the mounting bar with the fuse dividing plate.
Described fuse dividing plate is " L " type structure.
Described fuse dividing plate is a polycarbonate plate.
This kind low-voltage distribution cabinet with said structure has the following advantages with fuse structure:
This kind low-voltage distribution cabinet with the fuse mounting structure through a dividing plate L type, that make with polycarbonate plate is set below the low-voltage distribution cabinet fuse base; Dividing plate is fixed on the mounting bar with fuse base; Possibly influence adjacent fuse group, expansion accident scope owing to the arcing of fuse fusible core when effectively having solved the fuse single-phase short circuit; Simultaneously, it is near owing to installing to solve fuse, the problem of security protection during plug fuse fusible core.
2. this kind low-voltage distribution cabinet is simple with the fuse mounting structure, and effect is obvious, has good application and popularization value.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described further:
Fig. 1 is the structural representation of the utility model.
Fig. 2 is the left TV structure sketch map of structure shown in Figure 1.
In Fig. 1-2,1: the fuse fusible core; 2: fuse base; 3: the fuse dividing plate; 4: mounting bar.
Embodiment
By Fig. 1 for the utility model low-voltage distribution cabinet with fuse mounting structure sketch map, Fig. 2 is the left TV structure sketch map of structure shown in Figure 1.Combined to know that this kind low-voltage distribution cabinet is used the fuse mounting structure that comprise fuse fusible core 1 and fuse base 2, the below of fuse base 1 is provided with the fuse dividing plate 3 of " L " type by structure shown in Fig. 1-2, fuse dividing plate 3 is a polycarbonate plate.Fuse base 1 is fixed on the mounting bar 4 with fuse dividing plate 3.Fuse fusible core 1 when effectively having solved the fuse single-phase short circuit is because arcing possibly influence adjacent fuse group, expansion accident scope.It is near owing to installing to solve fuse simultaneously, the problem of security protection during plug fuse fusible core 1.
Claims (3)
1. a low-voltage distribution cabinet is used the fuse mounting structure; Comprise fuse fusible core (1) and fuse base (2); It is characterized in that: the below of described fuse base (1) is provided with fuse dividing plate (3), and fuse base (1) is fixed on the mounting bar (4) with fuse dividing plate (3).
2. a kind of low-voltage distribution cabinet according to claim 1 is used the fuse mounting structure, it is characterized in that: described fuse dividing plate (3) is " L " type structure.
3. a kind of low-voltage distribution cabinet according to claim 1 and 2 is used the fuse mounting structure, it is characterized in that: described fuse dividing plate (3) is a polycarbonate plate.
