Abstract

The invention provides a conducting cooling bar comprising a conducting bar and a cooling mechanism connected with the conducting bar. The bottom surface of the cooling mechanism and the conducting bar are fixed in a superimposed manner, and the bottom surface area of the cooling mechanism is greater than the superimposed area of the cooling mechanism and the conducting bar. According to the invention, the conducting bar is connected with the cooling mechanism to reduce the temperature rise of the conducting bar to make a circuit breaker used fully without being used in a derating manner; and at the same time, the conducting cooling bar of the invention adopts the minimum heat transfer area to achieve the maximum cooling effect, so the production cost can be reduced.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a conductive radiator. Background technique [0002] In order to improve the breaking capacity of the circuit breaker, multi-pole series connection is often used to increase the arc voltage during the breaking process of the circuit breaker. The method of multi-pole series connection generally uses a conductive bar to connect the first terminal of the first pole with the first terminal of the second pole. This connection method has the advantage of keeping the circuit breaker compact in the shortest distance, but the terminal connection The heat dissipation area is small, making the temperature rise higher. [0003] The existing conductive row is generally a flat plate structure, which reduces the temperature rise through its own transition part. Due to the limitation of space size and cost, the size of the transition part of the conductive bar is small, so that...
