Description
Technical Field
The invention relates to the field of expansion joints, in particular to a telescopic component in an expansion joint.
Background
In actual use, the bus duct is provided with an expansion joint at intervals of 60m according to regulations, and the expansion joint is used for absorbing deformation of the bus duct caused by heat expansion and cold contraction.
The research direction of expansion joints at home and abroad is how to improve larger expansion capacity under the condition of not influencing power transmission capacity, and the current solutions have two kinds: 1. an elastic component is adopted; 2. a more excellent mechanical structure is adopted. However, the existing elastic component with certain electric conduction capability is often expensive, so that the most economical and effective solution is to adopt a better mechanical structure at present.
Compared with the straight line shape and the round shape, the omega-shaped has better expansion performance, but when a plurality of omega-shaped are connected, the structure is often unstable, and in actual use, the situation that the deformation of each of a plurality of omega-shaped notches is different often occurs, under the situation, the deformation of the omega-shaped notch positioned in the middle is far more than that of the omega-shaped notch positioned in the middle of two ends, at the moment, the middle omega-shaped notch can be excessively deformed to cause the breakage of a copper sheet conductor at a dangerous point in the middle of the omega-shaped notch, so that the use is influenced, and unnecessary production accidents are caused.
Disclosure of Invention
The invention aims to solve the defects in the prior art and provide the expansion joint with strong expansion performance and good stability.
The bus duct connecting structure with the compensation function comprises a duct body, wherein a plurality of copper sheet conductors which are distributed at equal intervals are arranged in the duct body, insulating baffles are arranged between two adjacent copper sheet conductors, a plurality of first omega-shaped notches which are distributed at equal intervals are arranged on the copper sheet conductors along the length direction, and a second omega-shaped notch which is opposite to the opening direction of the first omega-shaped notch is arranged between every two adjacent first omega-shaped notches; soft filling columns are arranged in the first omega-shaped notch and the second omega-shaped notch. The copper sheet conductor is used for connecting copper bars in the two bus grooves.
In order to improve the elastic deformation capacity of the soft filling column, the soft filling column is made of PU or silica gel.
In order to provide better expansion deformation and ensure structural stability, the length of the copper sheet conductor is 200-400mm.
The beneficial effects are that:
1. the linear structure is changed into a plurality of omega-shaped notches which are distributed at intervals, and the characteristic that the omega-shaped notches are telescopic is utilized to provide a certain elastic deformation capacity for the copper sheet conductor with poor elastic deformation performance, so that a better length compensation capacity can be provided for the bus duct.
2. Compared with the traditional single-sided arrangement, the double-row array distribution mode is adopted, and the omega-shaped notches arranged at intervals in two directions can improve the structural stability of the whole device to a certain extent, and the installation requirement is reduced.
3. And a filling column is filled in each omega-shaped notch, so that the deformation can be uniformly dispersed into each omega-shaped notch to prevent the occurrence of overlarge deformation of each omega-shaped notch, and the insulating material with good elastic performance is used for providing elastic force to prevent the omega-shaped notch from excessively deforming to cause the breakage of a copper sheet conductor, thereby affecting the use and causing unnecessary production accidents.

Detailed Description
The present invention will be further described in detail with reference to the following examples and drawings for the purpose of enhancing the understanding of the present invention, which examples are provided for the purpose of illustrating the present invention only and are not to be construed as limiting the scope of the present invention.
As shown in fig. 1-2, a bus duct connecting structure with a compensation function comprises a duct body, wherein a plurality of copper sheet conductors 1 which are distributed at equal intervals are arranged in the duct body, an insulating baffle 2 is arranged between every two adjacent copper sheet conductors 1, a plurality of first omega-shaped notches which are distributed at equal intervals are arranged along the length direction of each copper sheet conductor, and a second omega-shaped notch which is opposite to the opening direction of the first omega-shaped notch is arranged between every two adjacent first omega-shaped notches; the first omega-shaped notch and the second omega-shaped notch are respectively internally provided with a soft filling column 3 made of PU, and the length of the copper sheet conductor is 200-400mm.
The working process comprises the following steps:
taking a 600m long wire conveying pipeline as an example, the bus duct is not extruded and deformed in order to ensure the deformation of the bus duct due to thermal expansion and contraction. A connecting mechanism with compensation function is arranged between two bus ducts at intervals of about 60m to connect the bus ducts.
The copper bars in the bus duct are specifically connected with the copper sheet conductors 1 in the connecting structure one by one, and the other ends of the copper bars are operated in the same way, so that the circuits are guaranteed to be communicated one by one and are not interfered with one another.
As shown in fig. 3, when the bus ducts in the circuit expand with heat and contract with cold, the deformation amount between the bus ducts is absorbed by the connection mechanism. The copper sheet conductor 1 in the connecting mechanism provides a certain compensation amount for the bus ducts through omega-shaped deformation, and the soft filling column 3 distributes the deformation amount of each part into each omega-shaped notch uniformly so as to prevent the copper sheet conductor from being damaged due to overlarge deformation of a single omega-shaped notch.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
