Abstract
The utility model relates to a bus duct connection reversed phase preventing structure for preventing reversed phase sequence of joints when in sectional connection of a bus duct. The structure comprises two bus ducts, a shell is sleeved on the outside of a joint insertion position of the two bus ducts, two sides of both an upper cover plate end portion and a lower cover plate end portion of casings of the bus ducts are provided with casing mounting holes for being connected with the shell, and the shell is provided with shell mounting holes corresponding to the casing mounting hole, the casing mounting holes on two sides of each cover plate end portion of each casing are asymmetrical while number and position of the shell mounting holes are corresponding to the those of the casing mounting holes. The bus duct connection reversed phase preventing structure has simple fabrication and low processing cost.
Description
Technical field
The utility model relates to a kind of bus duct that prevents that when the bus duct segmentation connects the joint phase sequence from putting upside down and connects the mistake proofing phase structure.
Background technology
The profile of bus duct is generally symmetrical structure, when pegging graft, two sections bus ducts because of the butt joint direction misphase takes place on the contrary mutually easily, cause the phase line of bus to follow the zero line connection to break down, existing bus duct generally is to do special mark on the bus duct joint in order to address this problem, perhaps joint is made asymmetric, make that like this processing and manufacturing of bus groove case and busbar is very inconvenient, strengthened processing cost.
Summary of the invention
Technical problem to be solved in the utility model is that a kind of bus duct connection mistake proofing phase structure simple, that processing cost is low of making is provided.
Bus duct of the present utility model connects the mistake proofing phase structure and comprises two bus ducts, joint splicing position outer cover one case at two bus ducts, on the housing of described bus duct, following two patch ends both sides are provided with and are used for the housing installing hole that is connected with case, relative position just with the housing installing hole is provided with the case installing hole on case simultaneously, patch ends at each housing, the housing installing hole that is positioned at both sides is asymmetric, the housing installing hole quantity difference or the position that promptly are positioned at patch ends both sides are asymmetric, and the quantity of case installing hole and position are corresponding with the housing installing hole.
Bus duct of the present utility model connects the mistake proofing phase structure and does not use special mark, and bus duct and inner busbar need not make more form in order to distinguish position, the left and right sides yet, makes to provide cost savings convenient processing and manufacture.
Description of drawings
The structural representation of Fig. 1 when to be two sections bus ducts of the present utility model do not install case under the state that misphase is installed;
The structural representation of Fig. 2 when to be two sections bus ducts of the present utility model do not install case under the correct state of installing;
Fig. 3 is the structural representation that two sections bus ducts of the present utility model are connected with case under the correct state of installing.
Embodiment
As shown in Figures 2 and 3, bus duct of the present utility model connects the mistake proofing phase structure and comprises two bus ducts 1, joint splicing position outer cover one case 2 at two bus ducts, on the housing of described bus duct, following two patch ends both sides are provided with and are used for the housing installing hole 11 that is connected with case 2, relative position just with the housing installing hole is provided with case installing hole 21 on case 2 simultaneously, patch ends at each housing, the housing installing hole 11 that is positioned at both sides is asymmetric, the housing installing hole quantity difference or the position that promptly are positioned at patch ends both sides are asymmetric, and the quantity of case installing hole 21 and position are corresponding with the housing installing hole.
Have only when two sections bus ducts connect in position shown in Figure 2, the case installing hole at case two ends can all be aimed to finish and be connected with the housing installing hole.If during the installation site misphase of two sections bus ducts, then the position of housing installing hole as shown in Figure 1, at this moment case can't be connected simultaneously with two sections bus ducts.Therefore, when installing as long as the misphase phenomenon of bus duct just can not take place in being installed on two sections bus ducts 1 that case 2 can be correct.
Claims (1)
1. a bus duct connects the mistake proofing phase structure, comprise two bus ducts (1), joint splicing position outer cover one case (2) at two bus ducts, upper and lower two patch ends both sides of the housing of described bus duct are provided with and are used for the housing installing hole (11) that is connected with case (2), go up relative position just at case (2) simultaneously and be provided with case installing hole (21) with the housing installing hole, it is characterized in that: in the patch ends of each housing, the housing installing hole (11) that is positioned at both sides is asymmetric, and the quantity of case installing hole (21) and position are corresponding with the housing installing hole.
