Embodiment 2

[0145] The difference from Scenario 1 is that if Figure 12 As shown, in the embodiment of the present application, the side of the positioning structure 50 facing away from the circuit breaker 30 is connected to the subframe 20 through an adhesive layer 56 .

[0146] The power distribution system 10 provided in the embodiment of the present application can increase the connection stability between the positioning structure 50 and the subframe 20 by providing an adhesive layer 56 on the positioning structure 50 , and this connection method adopts a simple structure and low cost.

[0147] It should be noted that the adhesive layer 56 can be arranged on the side of the positioning structure 50 facing away from the circuit breaker 30 , or on the side of the subframe 20 facing the outside of the accommodating groove, so that the positioning structure 50 and the subframe 20 can be reliably connected. And ensuring that the address code 55 on the positioning structure 50 corresponds ...

Embodiment 3

[0149] In a further embodiment of the present application, a magnetic material (not shown) is provided on the side of the positioning structure 50 facing away from the circuit breaker 30 , and the positioning structure 50 is connected to the subframe 20 by attracting the magnetic material to the subframe 20 .

[0150] It should be noted that the shape, structure, and quantity of the magnetic material do not limit the protection scope of the technical solution of the present application, as long as the technical solution that connects the positioning structure 50 and the subframe 20 by arranging magnetic materials falls within the protection scope of the application .

[0151] The power distribution system 10 provided in the embodiment of the present application implements the connection between the positioning structure 50 and the subframe 20 by setting magnetic materials, which not only has a simple structure, but also can be reused, which is energy-saving and environmentally ...

Abstract

The embodiment of the invention provides a power distribution system and a circuit breaker position acquisition method. The power distribution system comprises a plug-in frame, a single board located in the plug-in frame and at least one circuit breaker, wherein the single board comprises a plurality of slots, a position signal acquisition device is arranged on the single board, and is used for acquiring the address of any slot on the single board, the first end of each circuit breaker extends into the plug-in frame and is plugged in the slot position of the single board, the second end of each circuit breaker is located at the opening end of the plug-in frame, the opening end of the plug-in frame is provided with an address code, the address code corresponds to the address of the slot position on the single board, and each circuit breaker corresponds to at least one address code. According to the invention, the problem that the existing power distribution system cannot confirm the specific position of the fault circuit breaker is solved.

Description

technical field [0001] The invention relates to the technical field of power distribution systems, in particular to a power distribution system and a method for collecting positions of circuit breakers. Background technique [0002] In the generation, transmission and use of electricity, power distribution is an extremely important link. The power distribution system includes transformers and various high and low voltage electrical equipment, and the circuit breaker is a kind of electrical appliance with a large amount of use. The circuit breaker can cut off the faulty circuit in the power grid according to the signal size of the current and voltage in the power grid system, so as to ensure the normal operation of each line in the power grid and meet the normal power consumption of users. [0003] When the circuit breaker is in use, it is usually assembled in the subrack for power distribution. Specifically, a single board is arranged in the accommodation slot of the subrack...
