Abstract
The utility model relates to a small-bus connecting structure for a switch cabinet. The connecting structure comprises a plurality of copper bars are in pairwise connection, and is characterized in that threaded rod heads are arranged at the end parts of the copper bars, and the end parts of every two adjacent copper bars are in threaded connection through a screw cap pipe with internal threads. The small-bus connecting structure for the switch cabinet has the advantages that the structure is simple, the technical problems of heating, looseness and virtual connection at joints, large conductive resistance and much current loss are radically solved through simple threaded connection, normal operation of small buses is ensured, and the service life is prolonged.
Description
Technical field
The utility model relates to switch cubicle, the little bus connection structure of especially a kind of switch cubicle.
Background technology
The indoor armored withdraw type metal enclosed switchgear of KYN28A-12 type is 3.6kV～12kV three-phase alternating current 50Hz single busbar connection and bus sectional lized the complete sets of equipment; be mainly used in power plant, medium and small generator and send being subjected to electricity, sending electricity and large-scale high-tension motor starting etc. of secondary substation of electricity, industrial and mineral enterprises and institutions distribution and electric industry system; carry out the usefulness of control, protection, monitoring; function admirable; moderate; can adapt to the electricity market development need; filled up the blank of this rank mesohigh switchgear of China effectively, be highly commended by customers deeply.Cabinet pushes up the top that little bus is installed in switch cubicle in the KYN28A-12 Medium Voltage Switchgear, be to run through the control power supply that connects whole mesohigh switchgear, generally have 10 ~ 15 the tunnel, select for use the 6 square copper rods the same to couple together usually, form the conductive carrier that runs through connection with the switch cubicle width.Traditional connected mode as shown in Figure 1, adjacent two copper rods 1 use fixture 4 fixedly connected after misplacing mutually again.But such syndeton can cause the joint heating, loosening virtual connection, and conductive resistance increases, and current loss is also big, the electricity wasting energy.In view of the foregoing, provide a kind of novel switch cubicle little bus connection structure.
Summary of the invention
The purpose of this utility model is to solve existing the problems referred to above in the prior art, provides a kind of switch cubicle little bus connection structure.
The utility model is achieved in that the little bus connection structure of a kind of switch cubicle, comprise: some interconnective in twos copper rods, it is characterized in that: the end of described copper rod is the threaded rod head, and the end of adjacent two copper rods is connected by a nut gas thread with internal thread.
Advantage of the present utility model: simple in structure, by simply being threaded, thoroughly solved joint heating, loosening virtual connection, conductive resistance is big and current loss is big technical problem, guarantee the operation of working normally of little bus, and prolong its useful life.
Description of drawings
Fig. 1 is the schematic diagram of prior art.
Fig. 2 is a structural representation of the present utility model.
Below in conjunction with drawings and Examples the utility model is elaborated.
Embodiment
Among Fig. 2, the little bus connection structure of a kind of switch cubicle, comprise: some interconnective in twos copper rods 1, it is characterized in that: the end of described copper rod 1 is a threaded rod head 2, the end of adjacent two copper rods is threaded by a nut pipe 3 with internal thread, promptly be machined as screw head, join the cover capped pipe of an internal thread, two copper rod screw thread butt joints at two of existing copper rod.Since adopt the fixed form that is threaded, more solid and reliable than previous with fixed block and bolt, and can not produce the situation of heating, improved the problem of existing connection.
Below only expressed execution mode of the present utility model, it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model patent scope.Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model design, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
Advantage of the present utility model: simple in structure, by simply being threaded, thoroughly solved joint heating, loosening virtual connection, conductive resistance is big and current loss is big technical problem, guarantee the operation of working normally of little bus, and prolong its useful life.
Claims (1)
1. little bus connection structure of switch cubicle, comprising: some interconnective in twos copper rods is characterized in that: the end of described copper rod is the threaded rod head, the end of adjacent two copper rods is connected by a nut gas thread with internal thread.
