Technical Field

The invention relates to the field of circuit breakers, in particular to an intelligent circuit breaker for metering and sampling based on a bimetallic strip.

Background

The circuit breaker is used for monitoring a power supply and protecting a power supply and power grid system, when the load of the power grid system is continuously overloaded within a set time, a switching-off tripping command is sent out, and a mechanical actuating mechanism of the circuit breaker immediately switches off and cuts off the power supply so as to protect the power supply and power grid system.

When the circuit breaker works, current is carried between an incoming line terminal and an outgoing line terminal of the circuit breaker, the current in a circuit can fluctuate, and the current passing through the circuit breaker is an important parameter of the circuit breaker in work, so that the current passing through the circuit breaker is necessary to be monitored.

Disclosure of Invention

In order to overcome the defects of the background art, the invention provides an intelligent circuit breaker for metering and sampling based on a bimetallic strip, which mainly solves the problem that the measurement is troublesome because a measuring strip needs to be added for measuring when the current passing through the circuit breaker is monitored.

The technical scheme adopted by the invention is as follows:

the utility model provides an intelligent circuit breaker based on bimetallic strip carries out measurement sampling, includes the casing, be equipped with bimetallic strip and circuit board in the casing, the circuit board has voltage acquisition module, be equipped with first detection joint and second detection joint on the bimetallic strip, first detection joint and second detection joint with voltage acquisition module on the circuit board is connected.

The casing includes mesochite, protecgulum and hou gai, form the utmost point inner chamber of L between mesochite and the protecgulum, form the utmost point inner chamber of N between mesochite and the back lid, bimetallic strip locates in the utmost point inner chamber of L, the circuit board is located the utmost point inner chamber of N, be equipped with on the mesochite and run through the groove, the utmost point inner chamber of N with the utmost point inner chamber of L passes through run through the groove intercommunication.

The first detection joint is connected with the circuit board through a lead, and the lead penetrates through the through groove.

The double-metal-sheet-type detection device is characterized by further comprising an arc striking sheet and a lock catch, wherein a connecting rod is arranged on the lock catch, the bottom of the double metal sheet is connected with the arc striking sheet, the top of the double metal sheet is arranged corresponding to the connecting rod, the first detection joint is arranged at the middle end of the double metal sheet, and the second detection joint is arranged below the first detection joint.
