Abstract
The invention provides a high-voltage vacuum circuit breaker support frame device with rhombic fins. The high-voltage vacuum circuit breaker support frame device comprises a vacuum arc extinguishing chamber (1) and an upper support fame (2), wherein the upper support frame (2) is arranged on the vacuum arc extinguishing chamber (1) and is connected by adopting a fastening screw (3), the upper support frame (2) can be matched with the closing action of the vacuum arc extinguishing chamber (1), and the upper support frame (2) is provided with a plurality of rhombic fins (4) used for heat radiation. The high-voltage vacuum circuit breaker support frame device has the advantages that the higher current-carrying capacity of a high-voltage vacuum circuit breaker can be realized, the conductivity is obviously improved, and the contact resistance can be reduced; the heat radiation area can be increased through the plurality of rhombic fins, the temperature rise heating of the vacuum arc extinguishing chamber is reduced, and the loop heat energy gathering of the whole circuit breaker is reduced.
Description
Technical field
The invention belongs to high voltage electrical apparatus technical field, relate to high-pressure vacuum breaker, be specifically related to a kind of high-pressure vacuum breaker holder device with rhombus wing.
Background technology
Reciprocal high-pressure vacuum breaker switch all has a wide range of applications at high pressure and national economy every field, in the part of high-pressure vacuum breaker, divide-shut brake cam is conducting element, and be also the vital part in high-pressure vacuum breaker switch, traditional bracing frame is arranged on vacuum interrupter, for conduction, but because the little heat radiation of its surface area is bad, the easy temperature rise of long-time use is overheated, and insulating part will be caused to burn, dangerous, cause great waste; And conductance is not high, also cause electric energy loss, uneconomical.
Summary of the invention
Occur the problem such as heating, not high, the electric energy loss of conductance for overcoming upper bracket, the present invention adopts upper bracket to carry out the thinking of installing.Concrete technical scheme is as follows:
There is the high-pressure vacuum breaker holder device of rhombus wing, comprise vacuum interrupter (1), upper bracket (2), it is characterized in that: described upper bracket (2) is installed on described vacuum interrupter (1), and adopt holding screw (3) to connect, described upper bracket (2) can coordinate the closed action of described vacuum interrupter (1), and described upper bracket (2) has multiple rhombus wing (4) for dispelling the heat.
Further, described rhombus wing (4) is symmetrical, and monolateral is 9.
Further, the material of described upper bracket (2) is copper, and the material of described screw (3) is steel.
Further, described upper bracket (2) is T2 red copper, and the steel of described screw (3) are Q235.
Compared with the prior art, the technique effect that the present invention is useful is, the present invention can realize the higher ampacity of high-pressure vacuum breaker, significantly improves conductance, can reduce contact resistance; Multiple rhombus wing can increase area of dissipation, and reduce vacuum interrupter temperature rise heating, the loop heat energy reducing whole circuit breaker gathers.
Accompanying drawing explanation
