A method for connecting master-slave circuit breakers in a distribution box and the distribution box

Abstract

The invention discloses a method for connecting master-slave circuit breakers in a power distribution box and the power distribution box, comprising: Step 1: Establishing a hand-in-hand communication connection; Step 2: The host re-numbers a plurality of sub-circuit breakers in sequence; Step 3 : Then execute the step of retrieving the number, and perform pairing one by one; Step 4: End the whole process of automatic retrieving and retrieving the number, and return to the normal mode.

Description

Technical field [0001] The invention relates to the field of circuit breaker equipment, and in particular to a method for connecting master and slave circuit breakers in a distribution box. Background technique [0002] As we all know, electrical components such as the main engine, sub-breaker, and leakage protector are generally installed in the distribution box. In the distribution box structure, it reasonably distributes electric energy through the main engine and each sub-breaker to facilitate the opening and closing operations of the circuit; at the same time, it has a higher safety protection level and can intuitively display the conduction status of the circuit. [0003] However, there are still some technical shortcomings in the prior art: the connection relationship between the host in the existing distribution box and each sub-breaker, leakage protection device, etc. has been fixed before leaving the factory, for example, a circuit breaker in a distribution box 1.

[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
