Connecting method of principal and subordinate circuit breakers in power distribution cabinet and power distribution cabinet

Abstract

The invention discloses a connecting method of principal and subordinate circuit breakers in a power distribution cabinet and the power distribution cabinet. The method comprises: step 1, building hand-in-hand communication connection; step 2, carrying out serial numbering to multiple subordinate circuit breakers again by a host; step 3, carrying out the step of retrieval numbering, pairing one by one; and step 4, finishing the whole automatic retrieval numbering process, recovering to a normal mode.

Description

technical field [0001] The invention relates to the field of circuit breaker equipment, in particular to a method for connecting master-slave circuit breakers in a distribution box. Background technique [0002] As we all know, electrical components such as the main engine, branch circuit breakers, and leakage protectors are generally installed in the distribution box. In the distribution box structure, it reasonably distributes electric energy through the main unit and each branch circuit breaker, which facilitates the opening and closing operation of the circuit; at the same time, it has a high level of safety protection and can intuitively display the conduction state of the circuit. [0003] However, there are still some technical defects in the prior art: the connection relationship between the main engine in the existing distribution box and each branch circuit breaker, leakage protection device, etc. has been fixed when leaving the factory, for example, there is a cir...

[0003] However, there are still some technical defects in the prior art: the connection relationship between the main engine in the existing distribution box and each branch circuit breaker, leakage protection device, etc. has been fixed when leaving the factory, for example, there is a circuit breaker in a distribution box 1. Circuit breaker 2, leakage protector 3, leakage protector 4, so that they are installed in the first position, the second position, the third position, and the fourth position in order from left to right. The host defaults Install circuit breaker 1 at the first position; install circuit breaker 2 at the second position; install leakage protector 1 at the third position; install leakage protector 2 at the fourth position; If the location is changed, when the host sends an instruction to location 1, the essence of receiving the instruction is circuit breaker 2, and the instruction itself needs to be sent to circuit breaker 1, which will cause a fault

The status quo is that complex software algorithms can be used to implement the protocol, but the algorithm is too complex, which is not conducive to the implementation of microcontrollers with scarce resources, and when the number of slave devices increases, the running time is long and the probability of failure increases
