Description

Block terminal protection architecture Technical Field The utility model belongs to the field of arc prevention of power distribution cabinets, and particularly relates to a protection structure of a power distribution cabinet. Background In the field of safe electricity utilization, the distribution box plays a vital role, and an air switch and a circuit breaker are arranged in the distribution box and serve as two main core components in the distribution box, so that the air switch and the circuit breaker are the main daemon appliance for safe electricity utilization. Meanwhile, the power supply can be cut off at dangerous moment, so that potential electric accidents are avoided, and the molded case circuit breaker is focused on the leakage phenomenon in the detection circuit. Once the leakage current is detected to exceed a preset safety range (generally set to 30 mA), the plastic-case circuit breaker can automatically cut off the circuit in an extremely short time, so that the occurrence of personnel electric shock accidents is effectively prevented. The function makes the molded case circuit breaker become important equipment which is indispensable for household electricity safety, a plurality of shunt switches are arranged according to different electricity utilization areas and electric appliance types in order to ensure the safety and stability of household electricity, a plurality of circuit breakers are arranged in the distribution box, and the safety and stability of the electricity utilization can be ensured and the service life of the electric appliance equipment can be effectively prolonged by correctly configuring the empty switch and the circuit breaker in the distribution box. In the distribution box, arc extinguishing baffles are required to be installed on the upper opening and the lower opening of each molded case circuit breaker, if the arc extinguishing baffles are not installed, sundries fall on the surface of the circuit breaker to form two-phase short circuit, an arc between the two phases is formed, the short circuit is caused, the arc extinguishing baffles are effectively blocked, and the use safety of the distribution box is protected; The arc-extinguishing baffle has the size, and the size is according to the electric current difference, and the size of arc-extinguishing baffle installation is also different, when installing, need be according to the installation environment around the moulded case circuit breaker, change the arc-extinguishing baffle of equidimension, can separate between the two phases, and present arc-extinguishing baffle structure as an organic whole, the size of baffle is fixed, can only be according to actual use, change the arc-extinguishing baffle of equidimension, and consequently, then the assembly condition of different block terminal needs to be installed, be equipped with the arc-extinguishing baffle of different regulations.
