Abstract

The invention discloses a circuit breaker with a vertical structure. A handle (1) of the circuit breaker is installed on an operating mechanism (19); the operating mechanism (19) drives an A phase rotating shaft (15) to rotate, so that moving contact systems (18) installed on the A phase rotating shaft can be driven to perform closing and opening operation; an insulated pull rod (10) is connectedto the A phase rotating shaft through an A phase shaft (7), and also connected to a B phase shaft (7) and a C phase shaft (7), so that the effect of linkage operation on A, B and C phase moving contact systems (18) can be achieved, and therefore, synchronous closing and opening of the A, B and C phase moving contact systems (18) can be guaranteed under the action of the operating mechanism (19); and the layout mode of the circuit breaker A, the circuit breaker B and the circuit breaker C is in a vertical structure mode. The power circuit of a single power distribution cabinet can be increasedby 2 times by using the circuit breaker with vertical structure, and therefore, the cost of user building electrical input can be greatly reduced, power distribution cabinet steel input can be saved,and the impact of reducing costs and improving effect can be achieved.

Description

technical field [0001] The invention relates to the technical field of structural design of a low-voltage circuit breaker in a power system, in particular to a vertical structure circuit breaker. Background technique [0002] In the field of low-voltage electrical appliances, the internal structure of circuit breakers only has horizontal wiring, that is, two-pole circuit breakers, three-pole circuit breakers, and four-pole circuit breakers are all wired horizontally from left to right, so the width of the circuit breaker is relatively large. As a result, the number of circuits for power distribution in the same width distribution cabinet is relatively small, and most of the space in the actual depth direction of the distribution cabinet is empty and not fully utilized. To set up more circuits can only be realized by adding power distribution cabinets, so the building electrical investment will increase accordingly. [0003] According to statistics, almost all types of build...
