Problems solved by technology

In order to prevent dust, moisture, etc. from entering the bus duct, especially the gap between the air-type bus ducts and contaminating the bus duct, especially when there is no current passing through the bus duct to generate heat, if water vapor enters, it will easily corrode the bus duct, but if the bridge Completely closed, no air flow through the busbar to take away heat, and the busway temperature will be too high to cause damage

Embodiment 1

[0023] Such as figure 1 , 2 . As shown in 3, a profile assembled closed busbar bridge includes a profile shell 1, a number of busbars 2 fixed and arranged side by side in the profile, and there are air isolation gaps between the busbars. The busway and the busbar are sealed, and there is an air gap between the busbar and the busbar. A dielectric elastomer sealing structure is arranged at the air inlet at both ends between the two busbars. The dielectric elastomer sealing structure As a bar-shaped body arranged between two busbars, one electrode surface of the dielectric elastomer 3 is fixed on the busbar on one side, and an insulating gasket layer 4 is arranged on the other electrode surface of the dielectric elastomer. Defined as the free electrode surface 5, the free electrode surface is connected to the extended wire 6, and the end of the extended wire is controlled by the telescopic spring 7 to expand and contract relative to the busbar on the other side adjacent to it, a...

Embodiment 2

[0026] Such as Figure 4 As shown, the difference from the above embodiment is that the extended wire is an extended conductive plate body 8, and the conductive plate body is connected to the fixed end of the telescopic spring. When the telescopic spring is extended, the free end of the telescopic spring contacts the busbar. At the same time, the electrode surface is electrically connected to the busbar through the conductive plate body and the telescopic spring, and the current passes through the telescopic spring to generate heat, ensuring that the telescopic spring is always in a telescopic state when there is current passing through, and the telescopic spring shrinks when the busbar does not pass through the working current.

Embodiment 3

[0028] Such as Figure 5 , 6 As shown, different from the above-mentioned embodiments, the profile housing includes two upright sections 9, a beam section is connected between the two upright sections, and the beam section 10 is electrically connected to the busbar in the upright section.

[0029]In the above profile assembled closed busbar bridge, the dielectric elastomer sealing structure is arranged between the busbar plates at the lower ports of the two upright sections, and a vertically upward exhaust pipe 11 is communicated in the middle of the beam section. The nozzle of the pipe is provided with a cone valve, and the valve core 12 of the cone valve is opened and closed by the expansion and contraction control of the control spring 13 arranged in the exhaust pipe. The control spring is a two-way shape memory alloy spring. When the phase transition temperature of the shape memory alloy is high, the control spring stretches to open the cone valve core, and when the tempe...

Abstract

The invention provides a profile assembly type closed bus bridge frame, relates to electrical equipment, and solves the problem of dustproof, waterproof and heat dissipation contradiction of the bus bridge frame in the prior art. The profile assembly type closed bus bridge frame provided by the invention comprises a profile shell, a plurality of bus plates, and a dielectric elastomer sealing structure; the plurality of bus plates are arranged in the profile in parallel; the dielectric elastomer sealing structure is arranged at the air inlets at two ends between two bus plates; the dielectric elastomer sealing structure is a strip-shaped body arranged between the two bus plates; one electrode surface of a dielectric elastomer is fixed on the bus plate at one side; a sealing cushion layer is arranged on the other electrode surface of the dielectric elastomer; and a stretchable spring is a two-way shape memory alloy spring arranged between the two bus plates. According to the profile assembly type closed bus bridge frame provided by the invention, by utilization of the dielectric elastomer and the shape memory alloy, airflow between the bus plates can be automatically controlled to go in and out according to the temperature change.

Description

technical field [0001] The invention belongs to the technical field of electrical equipment, and relates to a busbar bridge, in particular to a profile assembled closed busbar bridge. Background technique [0002] With the emergence of modern engineering facilities and equipment, the power consumption of all walks of life is increasing rapidly, especially the emergence of many high-rise buildings and large workshops. The traditional cables used as power transmission wires can no longer meet the requirements in large current transmission systems. The parallel use of multiple cables brings a lot of inconvenience to the site installation and construction connection. Busbar bridge is a new type of distribution wire, compared with traditional cables, it fully demonstrates its superiority in large current transmission. The bridge frame is connected by bus ducts, and parallel bus panels for transmitting current are arranged in the bus ducts. In order to prevent dust, moisture, et...
