Description

A bus duct for high current transmission

Technical Field

The utility model belongs to the technical field of electric power engineering, in particular to a bus duct for large current power transmission.

Background Art

Bus duct is a device used for power transmission and distribution. It is usually made of metal, in the shape of long strips, with conductive materials such as copper or aluminum bars inside. Bus duct can carry large currents and is used to transmit electrical energy from the power source to different load devices, such as lighting equipment, motors, transformers, etc. It provides a safe and convenient way to distribute electricity, which can reduce the use of wires and simplify the wiring structure of the power system. At this stage, when the bus duct is in use, due to the large current passing through the bus duct during transmission, heat will be generated, and the bus duct needs to be dissipated.

After searching, the authorization announcement number CN218633249U and the authorization announcement date 2023.03.14 discloses a low-voltage, high-current bus duct, which solves the problems of uneven heat dissipation and poor heat dissipation effect of the existing low-voltage, high-current bus duct. It includes a lower shell, an upper shell, side panel one, side panel two and a number of conductive busbars. The lower shell is composed of a support body, a number of strip-shaped limiting heat-conducting plates, side baffle one, side baffle two, a number of heat dissipating fins and a number of heat dissipating fans. The strip-shaped limiting heat-conducting plates are fixedly connected to the top of the support body, and a slot matching the conductive busbar is formed between the strip-shaped limiting heat-conducting plates. The side baffle one and the side baffle two are respectively fixedly connected to the two sides of the bottom end of the support body, the strip-shaped limiting heat-conducting plates and the heat dissipating fan are fixedly connected to the bottom end of the support body, and a liquid cooling groove is opened inside the support body. Through the bus duct, the main body can have better heat dissipation performance, and can achieve uniform heat dissipation, avoiding uneven heat dissipation and affecting the service life.

However, the existing technology has the following shortcomings:

1. When installing the above-mentioned low-voltage and high-current bus duct, it is necessary to insert the conductive bus into the slot, and then install the upper shell, the side plate 1 and the side plate 2. In actual operation, since the upper shell is fixedly connected with the side plate 1 and the side plate 2 by a number of bolts, the operation during disassembly and assembly is relatively troublesome;

2. When the above-mentioned low-voltage and high-current bus duct is in use, heat is absorbed by the strip-shaped limiting heat-conducting plate, and heat is dissipated by the cooperation of the fan and the heat dissipation fins. However, in actual use, when it is installed in an environment with a small space, the heat cannot be discharged, which affects the heat dissipation effect.

Please refer to Figures 1 to 3. The utility model is a bus duct for high current power transmission, including a bus duct body 1, the bus duct body 1 includes a mounting box 103, the upper wall of the mounting box 103 is equidistantly fixed with partition bars 102, a conductive bus is fixed between two partition bars 102, and an insulating isolation layer is provided on the surface of the conductive bus to achieve an insulating effect, an upper cover 101 is provided above the partition bar 102, and the upper cover 101 is rotatably connected to the corresponding partition bar 102 through a hinge, a sealing gasket is fixed between the upper cover 101 and the partition bar 102 to ensure sealing, and baffle bars 1011 are symmetrically fixed on the left and right sides of the front wall of the upper cover 101, and the baffle bar 1011 is L-shaped, and a baffle 106 is provided on the inner side of the baffle bar 1011;

When the above arrangement is used, the two operating plates 1042 are operated to move closer to each other, driving the crossbar 104 to move closer to each other, so that the connecting plate 1041 and the block 106 are moved inward until the block 106 is disengaged from the corresponding block bar 1011. At this time, the upper cover 101 is operated and rotated. Under the action of the hinge, the upper cover 101 is rotated to open the upper cover 101, and then the conductive busbar is placed between the two partition bars 102. Then, the upper cover 101 is rotated in the opposite direction until the upper cover 101 and the partition bar 102 are in a non-rotatable state under the cooperation of the block 106 and the block bar 1011.

A groove 1022 is provided inside the spacer bar 102, and the groove 1022 is communicated with the inside of the installation box 103. Spoilers 1031 are fixed equidistantly from left to right inside the installation box 103. With the above arrangement, the flowing cooling water will enter the groove 1022 under the action of the spoiler 1031 to absorb the heat of the spacer bar 102 for heat dissipation.

The inner side wall of the stopper 106 is fixed with a connecting plate 1041, which provides an abutting platform for the elastic member 105 and is used to connect the stopper 106 and the crossbar 104. The inner side wall of the connecting plate 1041 is fixed with the crossbar 104, and the inner end of the crossbar 104 is fixed with an operating plate 1042. By moving the operating plate 1042 to drive the crossbar 104 to move, the connecting plate 1041 can drive the stopper 106 to move.

The outer portion of the crossbar 104 corresponds to the front wall of the partition bar 102, and a limiting plate 1021 is fixed, so that the crossbar 104 can only move left and right, and the crossbar 104 and the limiting plate 1021 are in clearance, and the stopper 106 is set in a triangular shape. When the upper cover 101 is closed, since the stopper 106 is set in a triangular shape, it is only necessary to operate the front end of the upper cover 101 to move toward the installation box 103, and there is no need to manually operate the stopper 106 to move inward. The stopper bar 1011 moves along the surface of the stopper block 106 and will pass over the stopper block 106, and finally the upper cover 101 and the installation box 103 are in a relatively fixed state by utilizing the cooperation of the stopper block 106 and the stopper bar 1011;

An elastic member 105 is provided outside the cross bar 104, and the two ends of the elastic member 105 are respectively in contact with the corresponding limit plate 1021 and the connecting plate 1041.
