Problems solved by technology

[0004] However, when the input terminals of multiple single-P circuit breakers are connected in parallel through parallel copper bars, it is necessary to design parallel copper bars for each row of single-P circuit breakers, and single-P circuit breakers with different capacities in each row of single-P circuit breakers The width of the parallel copper bar is also different, and the distance between the claws of each copper bar in the parallel copper bar is also different. The parallel copper bar between the power system and each row of single-P circuit breakers occupies a relatively large space; When the P circuit breaker uses cables to realize the parallel connection scheme, there is one cable between each single P circuit breaker and the power system, multiple cables are connected in parallel, and the other end of each cable also needs to be connected to the power system with parallel copper bars , side-by-side cables and parallel copper bars need to occupy more space
[0005] Therefore, for the single-P circuit breaker in the prior art, when multiple single-P circuit breakers are connected in parallel, the circuit needs to occupy a large space

Abstract

The invention discloses a circuit breaker assembly and a single P circuit breaker. The single P circuit breaker comprises a shell and an input end installed on the shell. The shell is provided with a through hole, and a copper bar can be inserted into the through hole. The input end comprises a current conduction piece positioned in the shell; the copper bar which is installed on the shell, wherein the copper bar and the current conduction piece are overlapped, and one end of the copper bar can extend out of the shell; a pressing mechanism which is installed on the shell and tightly presses an overlapped part in the copper bar which is overlapped with the current conduction piece in the shell on the current conduction piece in a pressing state. When the parallel connection of input ends of a plurality of single P circuit breakers is needed, adding a cable for parallel connection, a parallel copper bar and the like are not needed, the parallel connection of a plurality of single P circuit breakers can be realized through the copper bar, the current conduction piece and pressing mechanism of each single P circuit breaker, and a circuit space in the parallel connection of a plurality of single P circuit breakers can be saved.

Description

technical field [0001] The invention relates to the technical field of electric control, in particular to a circuit breaker assembly and a single-P circuit breaker. Background technique [0002] At present, in the electrical control technology industry, the power supply system generally needs to supply power to multiple load devices, so the circuit breaker assembly used for the feeder output has multiple circuit breakers, especially in the case of AC single-phase power supply and DC communication power supply , The circuit breaker in the circuit breaker assembly used for feeder output is generally a single-P circuit breaker. When the power supply system supplies power to multiple load devices, it is necessary to parallel input the input terminals of multiple single-P circuit breakers in the circuit breaker assembly. [0003] In the prior art, when the input terminals of multiple single-P circuit breakers are connected in parallel, an additional parallel copper bar or cable n...
