Embodiment Construction
[0014] The present invention will be further explained below in conjunction with the drawings:
[0015] by figure 1 Combine figure 2 , image 3 As shown, the moving contact system of the universal circuit breaker includes a moving contact support 1 and a moving contact 2. The moving contact 2 is composed of a plurality of mutually parallel contact pieces 3 stacked on at least two positioning shafts 4, and each contact Two contacts 5 are provided on the sheet 3, and the movable contact 2 and the movable contact support 1 are connected by the guide shaft clamping plates 6 on both sides. The guide shaft clamping plate 6 is provided with a waist-shaped hole 7 corresponding to the positioning shaft 4 , Both ends of the positioning shaft 4 are located in the waist-shaped hole 7 and can slide to ensure the over-travel of the moving contact 2 when the circuit breaker is closed. The moving contact support 1 is provided with the contact piece 3 on the moving contact 2 Each contact piece ...

The invention discloses a universal circuit breaker moving contact system, which mainly solves the problems that the contact of the conventional circuit breaker has lower arc voltage during break and the breaking capacity is difficultly improved. The universal circuit breaker moving contact system is characterized in that: a moving contact (2) is connected with a moving contact support (1) through guide shaft clamping plates (6) on two sides; waist-shaped holes (7) corresponding to a positioning shaft (4) are formed on the guide shaft clamping plates (6); two ends of the positioning shaft (4)are positioned in the waist-shaped holes (7) and can slide; spacers (9) matched with contact plates (3) on the moving contact (2) are arranged on the moving contact support (1); each contact plate (3) is positioned between the spacers (9); and a spring (10) is respectively arranged between each contact plate (3) and the moving contact support (1). The contact of the universal circuit breaker moving contact system has a dual-break structure, and the arc voltage is improved during the break. Therefore, the breaking capacity is improved, simultaneously the modular and combined circuit breaker isconvenient to assemble and disassemble.
Description
Technical field [0001] The invention relates to a universal circuit breaker, in particular to a universal circuit breaker moving contact system. Background technique [0002] Universal circuit breakers are used to distribute electrical energy and protect lines and power equipment from overloads, undervoltages, short circuits, etc. Under normal conditions, they can be used for infrequent switching of lines. The main technical performance that determines the performance of a universal circuit breaker is the rated ultimate short-circuit breaking capacity Icu, the rated operating short-circuit breaking capacity Ics and the rated short-circuit withstand current Icw. Therefore, it is very necessary to adopt various technologies to improve the main technical performance, whether from the aspect of improving the technical level of low-voltage electrical appliances or improving the market effectiveness of low-voltage electrical appliance manufacturers. The movable contact of the existing...
