Title:
POWER DISTRIBUTION PLUG-IN FRAME AND POWER DISTRIBUTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/272577
Kind Code:
A1
Abstract:
The present application relates to the technical field of circuits. Disclosed are a power distribution plug-in frame and a power distribution device. The power distribution plug-in frame comprises a frame body and an acquisition board; the acquisition board is provided inside the frame body; the acquisition board comprises multiple connection terminals and multiple controllers. Second ends of at least two of the multiple connection terminals are connected to a same controller. First ends of at least some of the multiple connection terminals are inserted into insertion holes of one or more circuit breakers, and the at least some connection terminals have one-to-one correspondence to the one or more circuit breakers. Each of the at least some connection terminals obtains a state signal of a corresponding circuit breaker, and transmits the state signal to a corresponding controller. The controller sends a control signal to the circuit breaker corresponding to the state signal by means of the corresponding connection terminal according to the state signal, and the control signal controls the on/off of the circuit breaker corresponding to the state signal. According to the solution, the number of controllers on the acquisition board is decreased, and the cost of materials of the acquisition board is reduced.
