Small-sized direct-current circuit breaker with electric operation mechanism

Abstract

The invention discloses a small-sized direct-current circuit breaker with an electric operation mechanism. The small-sized direct-current circuit breaker comprises a first insulation shell and a second insulation shell which are arranged in parallel; a handle, at least one of overload and short circuit protection devices, an operation mechanism, a first tripping rod, a moving contact, a static contact, an arc extinguishing chamber, a wiring terminal and a conductor are arranged in the first insulation shell; the electric operation mechanism, a driving disc and a current collector are arrangedin the second insulation shell; and one end of the conductor is connected with one end of the overload protection device or the short circuit protection device, and the other end of the conductor sequentially penetrates through the hole centers of the first insulation shell, the second insulation shell and the current collector and then is connected with the wiring terminal. The small-sized direct-current circuit breaker can realize electricity utilization information collection and remote switching control on electric equipment.

Description

technical field [0001] The invention relates to the field of low-voltage electrical appliances, in particular to a small DC circuit breaker with an electric operating mechanism. Background technique [0002] With the country's advocacy of energy conservation and emission reduction, different companies are paying more and more attention to the energy efficiency management of power distribution systems. In order to comprehensively improve the multi-dimensional energy saving needs of reducing energy consumption, improving efficiency, and ensuring operation, etc., From the original passive analysis data to active analysis data, in order to better realize energy efficiency management, it is generally necessary to adopt management methods of information digitization and refined management. Enterprises need to collect the electricity consumption information of the loads in the running power distribution system to achieve the purpose of collecting energy consumption data and finding...

Problems solved by technology

Although this solution reduces the complexity of installation, simplifies external wiring, and improves assembly efficiency compared with the previous solution, the module that integrates the circuit breaker function and power consumption information collection function has increased dimensions compared with traditional circuit breakers. It is still necessary to increase the internal space size of the distribution box, which cannot meet the needs of functional upgrading and transformation in the existing distribution box, greatly increasing the transformation cost and reducing the transformation efficiency
